▼ Despite a recent focus on understanding cumulative load, researchers still prefer to analyze the data using mean and peak values. At the same time, technological advancements have provided biomechanists with methods of collecting large amounts of data pertaining to joint loading. Waveform analysis offers another option that will become increasingly relevant, as wireless data collection devices become common place and provide access to waveforms from many hours of recording. The overall objectives of this research were to demonstrate some of the limits of current methods of biomechanical analysis, and introduce an alternative, and secondly, to propose a wireless system for use in field-based studies. An exploratory study using Functional Data Analysis (FDA) was completed on experimental lifting data. The results demonstrated that FDA can elucidate subtle differences in the curve shape outside of the peak areas typically used for statistical analysis that were attributed to fatigue. These findings support the need for a better understanding of how workers change their movement strategies as time progresses throughout the length of the workshift. To achieve this type of knowledge, a wireless data collection device utilizing inertial motion sensors (IMS) was introduced and validated for field use in the remaining three chapters. The IMS units in conjunction with an anthropometric model were tested against a traditional link segment model recorded in a gold-standard, video system. Testing that occurred in the entire reach space volume yielded errors as low as 5% for the lumbar moment, but errors also greatly exceeded 50% RMS error in some cases. Three hand switch alternatives were tested for their potential to provide external hand force timing and duration information to the link segment model, but none were found to be perfectly suitable in the current configuration. In conclusion, a wireless system based on IMS units has the potential to provide long-term data collection, but the development of the calibration routines and complexity of the underlying model must be improved. FDA was shown to have good potential for identifying subtle differences in curve shapes, and may become useful when long-term field-based data are readily available with the proposed IMS system.

▼ Representing upper extremity posture has posed a great challenge in the field of analytical biomechanics due to their great freedom of motion, which allows for large rotations in multiple directions. The Euler and quaternion methods, which are two commonly used methods for describing joint angles and body segment postures and movement, have great limitations when dealing with upper extremities. The planar projection method has also been used to represent joint angles and body segment postures and movement. The advantages of this method over other common methods are that it yields rotations with anatomical meaning that make it easy to understand from a clinical standpoint, it is not affected by Gimbal lock phenomenon, and is more accurate at large multi-axis rotations, which make it a good candidate for representing upper extremity posture. The disadvantages of this method are that it has some accuracy limitations when dealing with multi-axis rotations beyond 60 degrees, with complex rotation of the body structures inside of soft tissue, and has error associated with it when projecting onto global planes. This thesis investigated a modified planar projection approach using a simplified opto-electronic marker configuration to improve the accuracy when calculating upper extremity orientations. One modification of the method was that anatomical planes were calculated by defining orthogonal axes at the chest and rotating the axes to account for the slope of the chest. By defining the anatomical axes using anatomical landmarks of the upper torso, the body can move freely without disturbing the anatomical plane calculations. Projecting onto planes that are defined locally for different body segments rather than global segments, eliminated the angle errors previously associated with the planar projection method. This modified method was tested using human and mechanical tests and was applied to data pertaining to laparoscopic surgical hand tool use. The biomechanical risk exposure of the tasks was quantified from the postural results using a threshold technique and a novel approach to the Rapid Upper Limb Assessment.

▼ Digital humans in CAD systems can facilitate product and workspace designs through timely virtual ergonomic analyses. Currently, digital humans lack the capability of faithfully simulating human motions and motor capabilities. Existing methods are limited in that they do not provide: (1) planning of different types of motions on a unified framework, (2) consideration of alternative movement techniques, and (3) automatic adoption of new motions. To overcome these limitations, this research proposes a new approach for human motion planning termed Memory-based Motion Simulation (MBMS). In this context, motion planning utilizes joint angle templates stored in memory as the roots for producing new motions while conserving the properties of natural motions. The MBMS system consists of a motion database, a root motion finder, a movement technique classifier, and a motion modification algorithm. Given an input simulation scenario, the root motion finder searches the database for motions likely to approximate the scenario within specified limits. The selected motions are called root motions. Root motions may represent a mixture of fundamentally different 'alternative movement techniques.' To represent them, a Joint Contribution Vector (JCV) was developed to characterize a motion by quantifying the contributions of each joint motion to its movement goal achievement. Once characterized as JCVs, root motions can be grouped by statistical clustering to reveal alternative movement techniques. A motion modification algorithm alters root motions to meet given task requirements. The algorithm first identifies a root motion's underlying structure by resolving joint angle trajectories into sequences of motion primitives. This allows parameterization based on amplitude- and time-scaling for generalization of a root motion. An optimization scheme then modifies the root motion's joint motions according to new scenarios while maintaining the original structure, and minimizing changes in the angular velocity profiles and the terminal postures. Experimental testing was performed for validation. The MBMS was found to accurately predict various seated reaches and whole-body load transfer motions. The robustness of the JCV was demonstrated by its ability to distinguish lifting techniques and identify alternative movement techniques for whole-body motions. A case study demonstrated the utility of MBMS in improving the ergonomics of manual handling tasks. Advisors/Committee Members: Chaffin, Don B. (advisor).

O objetivo do presente trabalho foi avaliar comparativamente parâmetros biomecânicos (tanto antropométricos, quanto cinemáticos) de dados obtidos a partir do console Microsoft Kinect (2010). A avaliação destes parâmetros foi realizada para validar seu uso para obter informações complementares à Análise Ergonomica do Trabalho (AET) e em outras pesquisas, cujos objetivos envolvem o diagnóstico de uso de produtos ou ambientes de trabalho a partir da análises posturais e interações da população que o utiliza. A pesquisa com este console em particular é justificada uma vez que seu lançamento modificou o cenário da biomecânica, já que se trata de um equipamento acessível e portátil. Porém, sua precisão em relação à outros equipamentos ainda está em aberto, sendo inclusive, objeto de estudo de muitas pesquisas em andamento. Os dados obtidos por meio de sistemas de captura de movimentos tridimensionais permitem a avaliação de produtos, atividades e análises de interações homem-objeto. No campo do Design, é uma importante realização, uma vez que permite que profissionais tenham acesso à ferramenta que, anteriormente, era limitada à nichos especializados. O console foi comparado com o sistema de captura de movimentos inercial MVN Biomech (XSENS TECHNOLOGIES) e com o tradicional registro por meio de vídeo. Para obter dados do console Kinect, um software disponível no mercado foi selecionado a partir de critérios predefinidos para obter dados cinemáticos do console. Dois experimentos laboratoriais foram realizados: o primeiro, teve como objetivo obter dados operacionais dos equipamentos e suas limitações de uso; e o segundo foi realizado de forma a obter dados biomecânicos e compará-los a partir de três parâmetros estáticos e um dinâmico. Os parâmetros estáticos envolveram ângulos articulares e segmentares em posturas selecionadas e dimensões segmentares, onde a proposta foi avaliar dados antropométricos e as características do modelo biomecânico referente à manter os corpos rígidos durante a movimentação. O parâmetro dinâmico foi realizado de forma a obter dados de deslocamento global das articulações em movimentações selecionadas. Para possibilitar esta análise, uma plataforma digital foi desenvolvida, constituindo um campo neutro para o tratamento dos dados. A plataforma mantém os dados originais dos sistemas, permitindo a distinção entre os modelos biomecânicos e a retirada de dados que possam ser comparados. Os experimentos realizados permitiram avaliar a usabilidade do console, fornecendo diretrizes para seu uso. Para avaliar a utilização do console em ambientes reais de trabalho, foram realizados registros preliminares em laboratórios químicos, os quais se mostraram viáveis se as limitações, semelhantes às de sistemas baseados em tecnologia ótica, sejam consideradas. Futuras análises devem ser conduzidas para validar estatisticamente os resultados obtidos. Porém, considerando o objetivo do trabalho, pode-se concluir que o sistema avaliado é uma alternativa confiável no contexto proposto.

The aim of the present study…

Dissertação de Mestrado em Enfermagem de Reabilitação apresentada na Escola Superior de Saúde do Instituto Politécnico de Viana do Castelo

O estado de saúde, a segurança e o bem-estar dos trabalhadores de saúde estão diretamente relacionados com a qualidade dos serviços prestados aos clientes. Assim, perante a preocupação com a incidência das Lesões Músculo-esqueléticas Relacionadas com o Trabalho (LMERT) em Saúde nas Auxiliares de Ação Médica (AAM) de uma Unidade de Cuidados Continuados Integrados de Longa Duração e Manutenção (UCCILDM), tornou-se indispensável proceder à promoção da saúde e prevenção da doença neste local de trabalho. Deste modo, foram definidos os seguintes objetivos: conhecer as posturas adotadas aquando das mobilizações de clientes; promover mudanças ao nível das posturas adotadas durante as mobilizações de clientes; informar e formar sobre o risco de LMERT no desempenho da sua atividade profissional; formar para aquisição de posturas corretas durante os posicionamentos e transferências de clientes; avaliar a recetividade à correção da mecânica postural durante os posicionamentos e transferências de clientes. Optou-se por uma metodologia de investigação-ação, realizada com uma amostra constituída por 7 indivíduos (AAM) duma UCCILDM. Os dados foram recolhidos com recuso a um Questionário Sociodemográfico e Clínico; captura de imagens fotográficas sobre posturas adotadas durante a mobilização de clientes; formação em grupo e individual durante as atividades mencionadas anteriormente para esclarecer e aprofundar conhecimentos, finalizando-se com a análise ergonómica e postural recolhida através de Checklist, e aplicação de Questionário de Avaliação da Eficácia das Sessões de Formação. Os dados evidenciaram que estes profissionais de saúde apresentam uma multifatorialidade de riscos de desenvolverem LMERT, destacando-se os constrangimentos de natureza física e biomecânica (posturas adotadas), e de natureza individual (relativos à escassez de formação para a função que desempenham). A utilização dos músculos das pernas e das ancas e a utilização de equipamentos auxiliares foram identificadas como as estratégias menos eficazes na mobilização de clientes. Assim, perante a necessidade de implementar estratégias mais eficazes, que produzam melhores resultados, sugere-se a implementação de planos de formação enquanto momento de reflexão em equipa, com reciclagem periódica, a contratação sempre que possível de profissionais qualificados para a função e a aquisição de equipamentos auxiliares de mobilização.

The state of healthcare, safety and well-being are directly related with the quality of the services provided to the costumers. Thus, given the concern with the rate of work-related Musculoskeletal Disorders in the health of nursing assistants of long-term healthcare centers, it has become indispensable to diagnose the needs in order to promote health and prevent disease in this workplace. In this respect, the following objectives were defined: to know the postures adopted during mobilizations of…

Les troubles musculo-squelettiques (TMS) sont un problème majeur dans la société moderne, avec près de la moitié des travailleurs en industrie touchés. Ces troubles sont dus à des postures jugées à risques, tel que le travail avec les bras en hauteur ou le torse penché, aux poids de charges transportées, ou encore la répétitivité des tâches. Il est donc nécessaire de trouver des solutions permettant de diminuer le risque de TMS en limitant les mouvements et les postures à risques, et en améliorant ainsi l’ergonomie des postes de travail. Nous proposons dans cette étude des outils pour aller vers cette amélioration. L’objectif est d’automatiser l’évaluation de l’ergonomie à l’aide d’algorithmes d’apprentissage automatique. Nous avons pour cela collecté des bases de données du mouvement humain corps complet en s’inspirant d’activités provenant du monde industriel. Grâce à ces données, nous proposons une méthode d’apprentissage supervisé basée sur des modèles de Markov cachés pour reconnaître les postures et les actions d’un utilisateur. Puis nous proposons des métriques pour évaluer de façon automatique l’ergonomie ainsi qu’une méthode pour compresser les données du mouvement qui est une base pour aller vers la prédiction future de l’ergonomie. Enfin, nous présentons des interfaces qui permettraient de prévenir en temps réel un opérateur s’il effectue un mouvement à risque. Avec l’ensemble de ces outils, la finalité est de prévoir en temps réel l’ergonomie d’un opérateur afin de le prévenir s’il risque de se blesser, et qu’il puisse corriger son mouvement.

Musculoskeletal disorders (MSDs) are a major health issue in modern society, with almost half of workers in industry affected. These disorders are due to postures deemed to be at risk, such as overhead work or working with the torso bent, the weight of the carried loads, or the repetitiveness of the tasks. It is therefore necessary to find solutions to reduce the risk of MSD by limiting dangerous movements and postures, and thus improving the ergonomics of workstations. We propose in this study tools to move towards this improvement. The objective is to automate the evaluation of ergonomics, using machine learning algorithms. To do this, we collect databases of the whole human body movement inspired by activities from industrial environment. With these data, we propose a supervised learning method based on Hidden Markov Models to recognize postures and actions of a user. Then we propose metrics to automatically evaluate ergonomics and a method to compress the movement data. This is a brick to go towards the prediction of ergonomics. Finally, we present modalities to allow an operator to be warned in real time if he performs a risky movement. With all these tools, the final goal is to predict in real time the ergonomics of a user in order to warn him before risking to be injured. Thus he can correct his movement.

▼ Accurate risk assessment tools and methods are necessary to understand the relationship between occupational exposure to physical risk factors and musculoskeletal disorders. Ergonomists typically consider direct measurement methods to be the most objective and accurate of the available tools. However, direct measurement methods are often not used due to cost, practicality, and worker/workplace disruption. Inertial measurement units (IMUs), a relatively new direct measurement technology used to assess worker kinematics, are attractive to ergonomists due to their small size, low cost, and ability to reliably capture information across full working shifts. IMUs are often touted as a field-capable alternative to optical motion capture systems (OMCs). The error magnitudes of IMUs, however, can vary significantly (>15°) both within and across studies. The overall goals of this thesis were to (i) provide knowledge about the capabilities and limitations of IMUs in order to explain the inconsistencies observed in previous studies that assessed IMU accuracy, and (ii) provide guidance for the ergonomics community to leverage this technology. All three studies in this dissertation systematically evaluated IMUs using a repetitive material transfer task performed by thirteen participants with varying movement speeds (15, 30, 45 cycles/minute) and magnetic disturbance (absent, present). An OMC system was used as the reference device. This first study systematically evaluated the effects of motion speed and magnetic disturbance on the spatial orientation accuracy of an inertial measurement unit (IMU) worn on the hand. Root-mean-square differences (RMSD) exceeded 20° when inclination measurements (pitch and roll) were calculated using the IMU’s accelerometer. A linear Kalman filter and a proprietary, embedded Kalman filter reduced inclination RMSD to < 3° across all movement speeds. The RMSD in the heading direction (i.e., about gravity) increased (from < 5° to 17°) under magnetic disturbance. The linear Kalman filter and the embedded Kalman filter reduced heading RMSD to < 12° and < 7°, respectively. This study indicated that the use of IMUs and Kalman filters can improve inclinometer measurement accuracy. However, magnetic disturbances continue to limit the accuracy of three-dimensional IMU motion capture. The goal of the second study was to understand the capability of IMU inclinometers to improve estimates of angular displacements and velocities of the upper arm. RMSD and peak displacement error exceeded 11° and 28° at the fastest transfer rate (45 cycles/min) when upper arm elevation was calculated using the IMU accelerometer. The implementation of a Kalman filter reduced RMS and peak errors to < 1.5° and < 2.3°, respectively. Similarly, the RMS and peak error for accelerometer-derived velocities exceeded 81°/s and 221.3°/s, respectively, at the fastest transfer rate. The Kalman filter reduced RMS and peak errors to < 9.2°/s and < 25.1°/s, respectively. The third study was conducted to evaluate… Advisors/Committee Members: Fethke, Nathan B. (supervisor).

Hoje em dia, com os avanços constantes na indústria, novas áreas começam cada vez mais a ser foco de atenção por parte das organizações. Motivados pela procura de melhores condições para os seus colaboradores e por todos os benefícios que este tipo de intervenção oferece, tanto a curto, como principalmente a médio e longo prazo, a Grohe Portugal, mais especificamente o seu departamento de montagem, achou relevante potenciar a aplicação da Ergonomia nos seus postos de trabalho. Posto isto, esta dissertação pretende apresentar o trabalho desenvolvido junto da organização que teve como objetivo projetar e executar uma linha de montagem que tivesse em consideração os seguintes aspetos: • Ergonomia; • Automatização ou semi-automatização de operações; • Simplificação de aspetos operacionais; • Sistemas de abastecimento mais robustos e de fácil uso; • Simplificação de setups; • Definição de dimensões normalizadas para futuros projetos. As soluções encontradas tiveram como objetivo primordial satisfazer o maior número possível de colaboradores, sendo que para tal foram utilizados dados referentes a antropometria da população Portuguesa. Para a realização e conclusão deste projeto, o trabalho foi decomposto em varias etapas, de entre as quais se destacam: • Analise e estudo dos métodos de montagem; • Levantamento de todos os componentes e operações que constituem o processo de fabrico das diversas famílias onde foram implementados novos projetos; • Definição e uniformização da estrutura das novas linhas de montagem; • Estudo e definição da disposição dos componentes na nova linha, bem como da sua forma de abastecimento; • Projeto da linha de montagem em 3D com recurso ao software SolidWorks (DassaultSystemes, 2014); • Montagem final da linha, bem como o acompanhamento da sua fase de arranque. Durante o estagio foi ainda pensado e implementado um projeto paralelo com vista a constante manutenção e melhoria do departamento de montagem cujo objetivo, através de “plant walks”, e detetar de entre outras, situações de falta de identificação de componentes ou equipamentos, degradação de ferramentas, fugas ou derrames nas linhas, etc. O balanco final do trabalho foi bastante positivo, tendo-se alcançado melhorias em alguns índices de qualidade, tempos de abastecimento e condições ergonómicas dos postos de trabalho que sofreram intervenção, tendo essas melhorias resultado numa avaliação positiva por parte dos colaboradores que integram essas mesmas linhas.

Nowadays, with the constant advancements in industry, new areas begin increasingly to be the focus of organizations. Driven by the demand for better conditions for its employees and all the benefits that this kind of intervention receives, either in the short as mostly in the medium and long term, Grohe Portugal, more specifically its Assembly department thought relevant to potentiate the application of ergonomics in its workstations.

▼ Hoje em dia, e com os avanços tecnológicos a surgirem de forma constante, existem novas áreas que têm de ser consideradas com um foco importante por parte de todas as organizações, sendo uma delas a robótica industrial. Motivada em aumentar o seu output, as condições de trabalho para os seus colaboradores, bem como todas as condições de organização da logística interna, a Grohe Portugal, mais especificamente o departamento da montagem, achou relevante fazer um estudo de métodos e tempos, calculando os ganhos potenciais de aumento de output com introdução de robótica nas linhas dos cartuchos. Os objetivos principais seriam então, fazer uma restruturação de todo o layout dessas linhas, tendo como foco automatizar alguma(s) operação(ões), conseguindo assim uma melhoria significativa do output dessas linhas com o menor payback possível. Posto isto, esta dissertação pretende apresentar o trabalho desenvolvido junto da Grohe Portugal, que teve como objetivo fazer os estudos e a automatização de linhas de montagem de cartuchos, bem como melhorar algumas linhas de montagem tendo em conta fatores ergonómicos. Relativamente à automatização da linha dos cartuchos, foi importante estudar todos os seguintes aspetos:  utilização de unidades robóticas;  ergonomia;  ganhos de produtividade;  automatizar ou semi-automatizar operações;  simplificar processos de montagem;  simplificar setups;  solicitar orçamentos;  elaborar caderno de encargos. Para a realização deste projeto, o trabalho desenvolvido foi decomposto em várias etapas, entre as quais se destacam:  análise e estudo dos métodos e sequências de montagem;  levantamento de todos os componentes e operações de montagem até à obtenção do cartucho final;  estudo de tempos de todas essas operações de montagem;  caraterização de um novo layout para as linhas com a introdução de unidades robóticas, tanto quanto possível, mais adequadas;  elaboração de caderno de encargos para ser enviado a empresas, para estas poderem apresentar uma orçamentação, bem como indicar as unidades robóticas mais adequadas para as tarefas pretendidas;  automatização da linha dos cartuchos. Relativamente ao projeto de novas linhas de montagem tendo em conta fatores ergonómicos, de forma a melhorar os sistemas de abastecimento e as condições de trabalho por parte dos operadores, foram postos em prática diferentes passos, nomeadamente:  identificação de todos os processos de montagem realizados pelos operadores na linha a melhorar;  estudo e definição da disposição dos componentes na nova linha, bem como a sua forma de abastecimento;  projeto da nova linha de montagem em 3D com recurso ao software SolidWorks;  realização prática da linha, acompanhando e ajudando a equipa da ferramentaria. O balanço final do trabalho foi bastante positivo, tanto na automatização das linhas de montagem dos cartuchos, em que todo o seu estudo foi alcançado com sucesso, como no melhoramento ergonómico das linhas de montagem, tendo-se alcançado melhorias em alguns índices de qualidade, tempos de abastecimento,… Advisors/Committee Members: Guedes, Pedro Manuel Barbosa, Silva, Manuel Fernando dos Santos.

▼ Ο αξιόπιστος και αποτελεσματικός ανθρωποκεντρικός σχεδιασμός προϊόντων και διαδικασιών παραγωγής αποτελεί μείζον ζήτημα της κατασκευαστική βιομηχανίας. Για το λόγο αυτό, πλήθος ελέγχων που αφορούν στη λειτουργικότητα, την ασφάλεια και την άνεση, τόσο των προϊόντων που χρησιμοποιούνται από τον άνθρωπο, όσο και των διαδικασιών παραγωγής που συμμετέχει ο ανθρώπινος παράγοντας, πραγματοποιούνται και αξιολογούνται σε περιβάλλον Η/Υ με τη χρήση λογισμικών προσομοίωσης και εικονικής πραγματικότητας. Η ρεαλιστική και αξιόπιστη αναπαράσταση της ανθρώπινης κίνησης μέσα σε εικονικό περιβάλλον, αποτελεί στις μέρες μας επιτακτική ανάγκη. Στο πλαίσιο αυτό, η παρούσα διατριβή επικεντρώνεται στο σχεδιασμό και την ανάπτυξη μιας νέας μεθοδολογίας μοντελοποίησης της ανθρώπινης κίνησης, που βασίζεται στην προσαρμογή μιας υπάρχουσας κίνησης σε νέα ανθρωπομετρικά δεδομένα και περιορισμούς του περιβάλλοντος εργασίας (εικονικού πρωτοτύπου ή σταθμού εργασίας). Η προτεινόμενη προσέγγιση αποσκοπεί στη δημιουργία ρεαλιστικών και αξιόπιστων κινήσεων ψηφιακών ανθρωποειδών με στόχο την προσομοίωσή τους σε εικονικό περιβάλλον, ώστε να εξαχθούν αξιόπιστα αποτελέσματα κατά την εργονομική αξιολόγηση του σχεδιασμού προϊόντων και σταθμών εργασίας σε γραμμή παραγωγής. Αρχικά, γίνεται εισαγωγή τόσο στη σπουδαιότητα, όσο και στα προβλήματα του εργονομικού σχεδιασμού με χρήση ψηφιακών ανθρωποειδών, που αποτέλεσαν και το κύριο έναυσμα της παρούσας έρευνας. Παρουσιάζονται τα αποτελέσματα της βιβλιογραφικής ανασκόπησης, που αφορούν σε μεθόδους μοντελοποίησης της ανθρώπινης κίνησης με χρήση τεχνολογίας ψηφιακών ανθρωποειδών, καθώς και σε λογισμικά προσομοίωσης ανθρώπινης συμπεριφοράς και εργονομικού σχεδιασμού. Στη συνέχεια, παρατίθεται μια εκτεταμένη ανάλυση που έχει ως στόχο τη βαθύτερη κατανόηση της ανθρώπινης κίνησης. Η ανάλυση αυτή βασίζεται στη θεωρία του Στατιστικού Σχεδιασμού Πειραμάτων και χρησιμοποιεί πειραματικά δεδομένα καταγραφής ανθρώπινων κινήσεων. Η Ανάλυση της Διακύμανσης χρησιμοποιήθηκε για τον καθορισμό των ανθρωπομετρικών χαρακτηριστικών που επηρεάζουν περισσότερο την ανθρώπινη κίνηση, καθώς και για την ποσοτικοποίηση της επιρροής τους στη διαφοροποίηση της κίνησης. Βάσει των αποτελεσμάτων της Ανάλυσης της Διακύμανσης, γίνεται ανάπτυξη ημι-εμπειρικών, προσθετικών μοντέλων κίνησης, τα οποία συσχετίζουν την επίδραση των ανθρωπομετρικών χαρακτηριστικών με τις τροχιές των αισθητήρων που τοποθετούνται πάνω στο ανθρώπινο σώμα για την καταγραφή της κίνησης. Ακολουθεί η στοιχειοθέτηση της προτεινόμενης μεθοδολογίας μοντελοποίησης. Δεδομένου ότι η ανθρώπινη κίνηση αναλύεται σε ένα σύνολο διαδοχικών στιγμιοτύπων, η μεθοδολογία μοντελοποίησης αποσκοπεί στη δημιουργία στάσεων σώματος ψηφιακού ανθρωποειδούς για κάθε στιγμιότυπο του επιθυμητού σεναρίου κίνησης. Ως σενάριο κίνησης ορίζεται κάθε δυνατός συνδυασμός “εργασίας – ψηφιακού ανθρωποειδούς – περιβάλλοντος εργασίας”. Για τη δημιουργία ενός στιγμιότυπου της νέας κίνησης, ο αλγόριθμος της μεθοδολογίας παράγει τυχαίες εναλλακτικές στάσεις σώματος, διασφαλίζοντας ταυτόχρονα την… Advisors/Committee Members: Χρυσολούρης, Γεώργιος, Pappas, Menelaos, Χρυσολούρης, Γεώργιος, Ανυφαντής, Νικόλαος, Παπαδόπουλος, Χρήστος, Ασπράγκαθος, Νικόλαος, Δέντσορας, Αργύρης, Αθανασίου, Γεώργιος, Παπαθεοδώρου, Θεόδωρος.

▼ Work-related shoulder disorders represent a significant subset of work-related musculoskeletal disorders. Shoulder tendinitis has a high prevalence in major populations of employees. There is an urgent need for hints and directions on how to evaluate risks for developing chronic work-related shoulder disorders, as well as for methods of assessing hazardous working conditions.The aims of this work were to assess usability and accuracy in techniques and methods for exploring arm positions and shoulder muscle activity and to investigate the pattern of shoulder muscle interplay regarding voluntary control. The aims were also to elucidate the relations between the external physical demands originating from working tasks and internal load on different structures in the shoulder and to propose a model for estimating the risk of developing acute and chronic work-related musculoskeletal disorders of the shoulder, by using observable data which characterize the exposure.Electromyography (EMG) and intramuscular pressure (IMP) measurements were used to assess shoulder muscle activity. Bipolar electrodes were used for acquisition of EMG from the superficial muscles and for deep lying muscles indwelling wire electrodes were used. Acquisition of IMP was accomplished by microcapillary infusion technique. A 3D motion analysis system (MacReflex) has been used for control and registration of arm postures.The results indicate that IMP and EMG measurements produce similar estimates of muscle load and that there were substantial differences in IMP generation between shoulder muscles. Extremely high IMPs were recorded in the supraspinatus muscle. The MacReflex motion analysis system was found to produce position data with an angle error less than 1.8( in biomechanical and ergonomic application. It was demonstrated that the activity of the descending part of the trapezius muscle could be voluntarily reduced to 56% of the initial activity, without altering external conditions, and that the main part of the trapezius load was transferred to the rhomboid major and minor and the transverse part of the trapezius. IMP measurements showed that accumulated muscle fatigue might occur in the infra- and/or supraspinatus, if the upper arm exceeds 30( of arm elevation and that impaired muscle blood flow might occur if the upper arm exceeds 50(. In the validation of the biomechanical shoulder model, it was established that the shoulder muscle forces estimated by the model acceptably agree with the shoulder muscle forces estimated by the EMG measurements, except for the levator scapulae and the supraspinatus, where estimations from EMG measurements were 53% and 207%, respectively, of the activity calculated by the model. In conclusion: feedback assisted reduction of trapezius activity will affect other shoulder muscles, MacReflex motion analysis system possesses adequate accuracy for biomechanical and ergonomic purposes and IMP recordings from the infra- and supraspinatus indicate the necessity of restricted arm positions in static or repetitive work.

▼ Although the automation level is high within the automotive industry, there is still a high number of manual labour tasks such as in assembly areas. Taking ergonomics programs into account is essential to improve the workstation designs and conditions, which should result in increases in worker output and reductions of discomfort. Work-related musculoskeletal disorders continue to be one of the main problems in the industry today. Exoskeletons are a new technology becoming increasingly important due to its potential reducing loads, they suppose a possible promising solution to advantage in manufacturing environments. The purpose of this study is to evaluate and compare how the use of three different models of exoskeletons affects the range of motion of workers at overhead assembly operations. EksoVest from EksoBionics, Paexo from Ottobock and MATE from Comau have been the passive upper body exoskeletons involved in the present project. To develop the comparison analysis an experiment was designed in which seventeen subjects participated including factory operators and students. The experiment consists of performing three different tasks (drilling operation and stretching) four times, one with each of the exoskeleton models and another without them. Observations, interviews and video and motion capture (Xsens equipment) recordings have been the elements involved in collecting the data. The results have shown that all the subjects agree that exoskeletons help in this specific overhead task, on the contrary, for tasks requiring a larger range of motion the performance decreases. Paexo was the preferred model followed by EksoVest and MATE respectively. However, none of the models got a complete positive valuation. In addition, statistical analysis of the motion capture recorded data have described a trend of keeping the arms raised when using the exoskeletons during the tasks than performing it without them. Positive and negative aspect, activation zone and uses of each of the exoskeleton models are also discussed. To conclude, the results of this thesis highlight the need for design improvements in order to allow a full range of movement to workers and increase user performance in a broader number of applications or tasks as well as to assure a more suitable implementation.

▼ Denna studie handlar om personalvårdsförmånen friskvårdstimmen parallellt med motionsvanor i allmänhet. Vi har i studien utgått från ett generellt hälsoperspektiv, för att sedan smalna av till att inrikta oss på hälsa inom arbetslivet, närmare bestämt friskvårdstimmen. Vår studie följer därmed en så kallad ”Top-down modell”. Syftet med denna studie är att undersöka vilka som nyttjar friskvårdstimmen samt vad som motiverar individer till att motionera. För att utforska detta har vi utgått från tre frågeställningar: vilken kategori av människor är det som motionerar och använder sig av friskvårdstimmen? Vad motiverar dessa individer? Hur kan man motivera anställda till motion och användandet av friskvårdstimmen? Studien är baserad på en kvantitativ undersökning i enkätform, inom en statlig organisation i centrala Karlstad. 169 respondenter besvarade enkäten. Vi anser oss ha ett brett urval då hela kontoret var med i undersökningen, vilket gjorde att vi fick en spridd fördelning i ålder och kön. Bland våra respondenter kan vi se att det finns en positiv inställning och en hög medvetenhet till motionens och friskvårdstimmens effekter. Dock är nyttjandet i praktiken inte lika stort i förhållande till respondenternas medvetenhet. Vi ser att man har en omgivande miljö som är motionsfrämjade, inte minst i och med att organisationen erbjuder friskvårdstimmen som personalvårdsförmån. Av de framkomna resultaten kan vi bland annat se att ålder är en bidragande faktor till hur mycket man använder friskvårdstimmen. Av våra respondenter motionerar kvinnor mer än män och motivationsfaktorer till motionen är för att hålla sig i form och för att förebygga skador och sjukdomar. Vidare är tidsbrist en bidragande orsak till varför man inte motionerar och nyttjar friskvårdstimmen. Vi menar att om organisationen vill utveckla friskvården bör man uppmärksamma att till en början koncentrera sig på dem som aldrig nyttjar friskvårdstimmen. Att erbjuda personlig rådgivning till dessa anställda anser vi skulle kunna vara en tänkbar motivationsfaktor till ökad motion. Detta eftersom det i vår studie framkom att mer information om motion inte skulle leda till ett högre motionsutövande. Vi är medvetna om att endast friskvårdstimmen i sig inte kan förändra ett beteendemönster, men att den kan vara ett inledande steg till att förbättra sin levnadsstil.

L’interaction Humain-Robot est un domaine de recherche en pleine expansion parmi la communauté robotique. De par sa nature il réunit des chercheurs venant de domaines variés, tels que psychologie, sociologie et, bien entendu, robotique. Ensemble, ils définissent et dessinent les robots avec lesquels nous interagirons dans notre quotidien.Comme humains et robots commencent à travailler en environnement partagés, la diversité des tâches qu’ils peuvent accomplir augmente drastiquement. Cela créé de nombreux défis et questions qu’il nous faut adresser, en terme de sécurité et d’acceptation des systèmes robotiques.L’être humain a des besoins et attentes bien spécifiques qui ne peuvent être occultés lors de la conception des interactions robotiques. D’une certaine manière, il existe un besoin fort pour l’émergence d’une véritable interaction humain-robot ergonomique.Au cours de cette thèse, nous avons mis en place des méthodes pour inclure des critères ergonomiques et humains dans les algorithmes de prise de décisions, afin d’automatiser le processus de génération d’une interaction ergonomique. Les solutions que nous proposons se basent sur l’utilisation de fonctions de coût encapsulant les besoins humains et permettent d’optimiser les mouvements du robot et le choix des actions. Nous avons ensuite appliqué cette méthode à deux problèmes courants d’interaction humain-robot.Dans un premier temps, nous avons proposé une technique pour améliorer la lisibilité des mouvements du robot afin d’arriver à une meilleure compréhension des ses intentions. Notre approche ne requiert pas de modéliser le concept de lisibilité de mouvements mais pénalise les trajectoires qui amènent à une interprétation erronée ou tardive des intentions du robot durant l’accomplissement d’une tâche partagée. Au cours de plusieurs études utilisateurs nous avons observé un gain substantiel en terme de temps de prédiction et une réduction des erreurs d’interprétation.Puis, nous nous sommes attelés au problème du choix des actions et des mouvements qui vont maximiser l’ergonomie physique du partenaire humain. En utilisant une mesure d’ergonomie des postures humaines, nous simulons les actions et mouvements du robot et de l’humain pour accomplir une tâche donnée, tout en évitant les situations où l’humain serait dans une posture de travail à risque. Les études utilisateurs menées montrent que notre méthode conduit à des postures de travail plus sûr et à une interaction perçue comme étant meilleure.

Human-Robot Interaction (HRI) is a growing field in the robotic community. By its very nature it brings together researchers from various domains including psychology, sociology and obviously robotics who are shaping and designing the robots people will interact with ona daily basis. As human and robots starts working in a shared environment, the diversity of tasks theycan accomplish together is rapidly increasing. This creates challenges and raises concerns tobe addressed in terms of safety and acceptance of the robotic systems. Human beings havespecific needs…

L'intérêt pour la robotique a débuté dans les années 70 et depuis les robots n'ont cessé de remplacer les humains dans l'industrie. L'automatisation à outrance n'apporte cependant pas que des avantages, car elle nécessite des environnements parfaitement contrôlés et la reprogrammation d'une tâche est longue et fastidieuse. Le besoin accru d'adaptabilité et de ré-utilisabilité des systèmes d'assemblage force la robotique à se révolutionner en amenant notamment l'homme et le robot à interagir. Ce nouveau type de collaboration permet de combiner les forces respectives des humains et des robots. Cependant l'homme ne pourra être inclus en tant qu'agent actif dans ces nouveaux espaces de travail collaboratifs que si l'on dispose de robots sûrs, intuitifs et facilement reprogrammables. C'est à la lumière de ce constat qu'on peut deviner le rôle crucial de la génération de mouvement pour les robots de demain. Pour que les humains et les robots puissent collaborer, ces derniers doivent générer des mouvements sûrs afin de garantir la sécurité de l'homme tant physique que psychologique. Les trajectoires sont un excellent modèle pour la génération de mouvements adaptés aux robots collaboratifs, car elles offrent une description simple et précise de l'évolution du mouvement. Les trajectoires dîtes souples sont bien connues pour générer des mouvements sûrs et confortables pour l'homme. Dans cette thèse nous proposons un algorithme de génération de trajectoires temps-réel basé sur des séquences de segments de fonctions polynomiales de degré trois pour construire des trajectoires souples. Ces trajectoires sont construites à partir de conditions initiales et finales arbitraires, une condition nécessaire pour que les robots soient capables de réagir instantanément à des événements imprévus. L'approche basée sur un modèle à jerk-contraint offre des solutions orientées performance: les trajectoires sont optimales en temps sous contraintes de sécurité. Ces contraintes de sécurité sont des contraintes cinématiques qui dépendent de la tâche et du contexte et doivent être spécifiées. Pour guider le choix de ces contraintes, nous avons étudié le rôle de la cinématique dans la définition des propriétés ergonomiques du mouvement.[...]

It was in the 70s when the interest for robotics really emerged. It was barely half a century ago, and since then robots have been replacing humans in the industry. This robot-oriented solution doesn't come without drawbacks as full automation requires time-consuming programming as well as rigid environments. With the increased need for adaptability and reusability of assembly systems, robotics is undergoing major changes and see the emergence of a new type of collaboration between humans and robots. Human-Robot collaboration get the best of both world by combining the respective strengths of humans and robots. But, to include the human as an active agent in these new collaborative workspaces, safe and flexible robots are required. It is in this context that we can apprehend the crucial role of motion…

Repetitive tasks, awkward hand/wrist postures and forceful exertions are known risk factors for work-related musculoskeletal disorders (WMSDs) of the hand and wrist. WMSD is a major cause of long work absence, productivity loss, loss in wages and individual suffering. Currently available assessment methods of the hand/wrist motion have the limitations of being inaccurate, e.g. when using self-reports or observations, or expensive and resource-demanding for following analyses, e.g. when using the electrogoniometers. Therefore, there is a need for a risk assessment method that is easy-to-use and can be applied by both researchers and practitioners for measuring wrist angular velocity during an 8-hour working day. Wearable Inertial Measurement Units (IMU) in combination with mobile phone applications provide the possibility for such a method. In order to apply the IMU in the field for assessing the wrist velocity of different work tasks, the accuracy of the method need to be examined. Therefore, this laboratory experiment was conducted to compare a new IMU-based method with the traditional goniometer and standard optical motion capture system. The laboratory experiment was performed on twelve participants. Three standard hand movements, including hand/wrist motion of Flexion-extension (FE), Deviation, and Pronationsupination (PS) at 30, 60, 90 beat-per-minute (bpm), and three simulated work tasks were performed. The angular velocity of the three methods at 50th and 90th percentile were calculated and compared. The mean absolute error and correlation coefficient were analysed for comparing the methods. Increase in error was observed with increase in speed/bpm during the standard hand movements. For standard hand movements, comparison between IMUbyaxis and Goniometer had the smallest difference and highest correlation coefficient. For simulated work tasks, the difference between goniometer and optical system was the smallest. However, for simulated work tasks, the differences between the compared methods were in general much larger than the standard hand movements. The IMU-based method is seen to have potential when compared with the traditional measurement methods. Still, it needs further improvement to be used for risk assessment in the field.

Upprepade uppgifter, besvärliga hand- / handledsställningar och kraftfulla ansträngningar är kända riskfaktorer för arbetsrelaterade muskuloskeletala störningar (WMSD) i hand och handled. WMSD är en viktig orsak till lång frånvaro, produktivitetsförlust, löneförlust och individuellt lidande. För närvarande tillgängliga bedömningsmetoder för hand / handledsrörelser har begränsningarna att vara felaktiga, t.ex. när du använder självrapporter eller observationer, eller dyra och resurskrävande för följande analyser, t.ex. när du använder elektrogoniometrarna. Därför finns det ett behov av en riskbedömningsmetod som är enkel att använda och som kan användas av både forskare och utövare för att mäta handledens vinkelhastighet under en 8-timmars arbetsdag. Wearable Inertial…

Ever wondered how trains arrive and depart on time? Traffic Control systems are there to help control the traffic flow, with many operators monitoring and taking actions when necessary. Operators of the traffic control systems use a keyboard and a mouse to interact. Current user interface and work setup consist of many usability issues that can be improved in order to increase operator’s efficiency and productivity in controlling the traffic. Interviewing users of the system and researching on related topics led to a newly proposed design in interaction, user interface as well as some suggestions for increasing productivity. Gesture-based interaction is introduced and simulated for traffic control systems that tend to improve the operation. Various gestures are designed such as panning, zooming and hovering the map using Leap Motion controller which enables intuitive interaction. These gestures aim to solve identified usability issues discovered during the interview with the user. The project aims to answer the following question: Can gesture-based interaction solve usability issues and establish the intuitive use of the CTC system? Performing exploratory research on this topic involved designing, implementing and testing hand gestures with users. From an ergonomic perspective, body posture and hand position of the operator is examined and suggested to use sit-to-stand workstations in order to reduce pain and discomfort while working. Gesture-based interaction eliminates finding mouse cursor on large screens, it enables fast request of detailed information and also it provides a better overview of the map surroundings. Laboratory tests confirm that gesture-based interaction brings more natural and intuitive use of traffic control systems. There is a big potential for gesture-based interaction to increase usability and bring efficient controlling for operators. It would reduce delays of the train and maintain safe traffic flow.

Har du någonsin undrat hur tåg anländer och avgaå i tid? Trafikledningssystem (CTC-system) hjälper till att kontrollera trafikflöet där operatörer övervakar och vidtar åtgärder vid behov. Operatörer av ett trafikledningssystem använder idag ett tangentbord och en mus för att interagera. Det nuvarande användargränssnittet och arbetsinstallationen består av många användbarhetsproblem som kan förbättras för att öka operatörens effektivitet och produktivitet för att kontrollera trafiken. Intervjuer med användare av systemet samt forskning om ämnet ledde till ett nytt föreslag av interaktion, utformning av användargränssnitt samt några förslag för att öka produktiviteten. Den gestbaserade interaktionen som infördes och simulerades för trafikkontrollsystemet tenderar att förbättra funktionen. Olika gester utformades som möjliggör för användaren att panorera, zooma och sväva över kartan. Gesterna implementerades med hjälp av Leap Motion Controller som möjliggör intuitiv interaktion.

▼ BACKGROUND and OBJECTIVES: Low-back overexertion injuries represent a large proportion of fireground “strains, sprains and muscular pains” and are a leading cause of disability and early retirement in firefighters. Given the inherently hazardous and unpredictable nature of many fireground activities, it is often infeasible to implement “task-focused” ergonomic controls and there are limited options to accommodate injured firefighters. Accordingly, effective and practical “worker-focused” injury prevention approaches are needed. Toward this end, four studies were conducted to address the following global thesis objectives: 1) Examine the possible role that firefighters’ personal movement strategies could have on their occupational low-back loading demands and injury potential; and 2) Compare the effects of two different exercise approaches on firefighters’ occupational low-back loading demands and injury potential. STUDY 1: Low-Back Loading Demands during Simulated Firefighting Tasks – Inter-Subject Variation and the Impact of Fatigue and Gender. Background: Non-modifiable fireground duties are considered hazardous for low-back health, but personal movement strategies could modulate low-back loading demands and injury potential. Study objectives were to quantify low-back loading demands during simulated firefighting tasks and to examine the impact of fatigue and gender on the peak loading response. Methods: Ten men and 10 women performed a battery of laboratory-simulated firefighting tasks before and following repeated bouts of a fatiguing stair-climbing protocol. An EMG-assisted three-dimensional dynamic biomechanical model was used to compute peak L4/L5 joint forces during task performance. Results: Peak low-back loading demands varied considerably between subjects and tasks, but 70% of all loading variables examined were of greater magnitudes in male subjects and 40% of all loading variables were of lower magnitudes in both males and females after stair-climbing. Some inter-subject variation in low-back loading was attributed to body size differences, but between- and within-subject differences in movement strategies also contributed to low-back loading variability between subjects and over time. Conclusions: Results of this study suggest that characteristics of individuals, tasks performed, and physical fatigue may influence peak low-back loading demands and injury potential in firefighters. Despite considerable inter-subject variation in the internal low-back loading response to fixed external task and environmental constraints, opportunities to attenuate low-back loading demands through movement behaviour adaptations alone may be limited to only a subset of fireground activities. STUDY 2: Ankle Immobilization alters Lifting Kinematics and Kinetics – Occupational Low-Back Loading Demands and Potential for Injury. Background: Firefighters with lingering lower extremity functional impairments could be forced to move in ways that increase their potential for sustaining occupational…

▼ The efficient and reliable human-centred design of products and processes is a major goal of the manufacturing industry. Thus, numerous aspects related to performance, safety and ergonomics, need to be verified using Simulation and Virtual Reality techniques, in the context of the product development procedure. The realistic and accurate representation of human motion in Virtual Environment is crucial for the reliability of the simulation results. In this context, this dissertation focuses on the design and development of a novel methodology for human motion modelling, based on the adaptation of a given motion of a digital human model to new anthropometrics and environment’s constraints (related to virtual prototype or workspace). The proposed approach aims at the generation of realistic and reliable digital human motions in order to drive computer manikins into a Virtual Environment, so as to obtain reliable evaluation results during ergonomic design of a product or a production line’s workspace. The introductory chapter presents both the importance and the limitations of the ergonomic design using computer manikins, which consisted the major motivation of this research work. State-of-the-art is presented next, concerning other approaches related to human motion modeling using computer manikins, as well as software tools for digital human modeling and ergonomic design. Next chapter presents an extensive analysis, which focuses on the better understanding of the human motion. This analysis is based on a Statistical Design Of Experiments (SDoE) and makes use of experimental motion captured data. Analysis of Variance (ANOVA) was performed for the determination of the impact factor of the anthropometric parameters influencing the human motion path. Semi-empirical additive models was developed next, based on the results of this analysis, which connects the effect of anthropometrics with the trajectories of the markers that are attached on the human body during the motion capture procedure. The composing of the proposed motion modelling methodology is following. Given that human motion is analysed by a set of sequential motion frames, the modelling methodology aims at the generation of digital human’s postures for each frame of the desirable motion scenario. Motion scenario is each possible combination of “task – computer manikin – environment”. For the creation of a new motion’s frame, the algorithm of the methodology generates alternative postures, ensuring the rejection of non-realistic and constraint-violating postures. The basic concept of the modelling methodology is based on the multi-criteria decision making, which is used for the alternatives’ evaluation and the selection of the best-ranked human postures that constitute the new human motion. The criteria concern both the extensionality of the new motion and the satisfaction of the new constraints, related to the geometric modifications of the working environment. The description of the primary and secondary components of the implemented system, as well as their…

▼ An ergonomically designed work environment may decrease work related musculoskeletal disorders, lead to less sick leaves and increase production time for operators and companies all around the world. Volvo Construction Equipment wants to deepen the knowledge and investigate more carefully how operators are actually sitting whilst operating the machines, how this affects placement of controls and furthermore optimize controls placements accordingly. The purpose is to enhance their product development process by suggesting guidelines for control placement with improved ergonomics based on operators’ sitting postures. The goal is to deliver a process which identifies and transfers sitting postures to RAMSIS and uses them for control placement recommendations in the cab and operator environments. Delimitations concerns: physical ergonomics, 80% usability of the resulted process on the machine types, and the level of detail for controls and their placements. Research, analysis, interviews, test driving of machines, video recordings of operators and the ergonomic software RAMSIS has served as base for analysis. The analysis led to (i) the conclusion that sitting postures affect optimal ergonomic placement of controls, though not ISO-standards, (ii) the conclusion that RAMSIS heavy truck postures does not seem to correspond to Volvo CE’s operators’ sitting postures and (iii) and to an advanced engineering project process suitable for all machine types and applicable in the product development process. The result can also be used for other machines than construction equipment. The resulted process consists of three independent sub-processes with step by step explanations and recommendations of; (i) what information that needs to be gathered, (ii) how to identify and transfer sitting postures into RAMSIS, (iii) how to use RAMSIS to create e design aid for recommended control placement. The thesis also contains additional enhancements to Volvo CE’s product development process with focus on ergonomics. A conclusion is that the use of motion capture could not be verified to work for Volvo Construction Equipment, though it was verified that if motion capture works, the process works. Another conclusion is that the suggested body landmarks not could be verified that they are all needed for this purpose except for those needed for control placement. Though they are based on previous sitting posture identification in vehicles and only those that also occur in RAMSIS are recommended, and therefore they can be used. This thesis also questions the most important parameters for interior vehicle design (hip- and eye locations) and suggests that shoulder locations are just as important. The thesis concluded five parameters for control categorization, and added seven categories in addition to those mentioned in the ISO-standards. Other contradictions and loopholes in the ISO-standards were identified, highlighted and discussed. Suggestions for improving…
