▼ Automated traffic light recognition is a key technology of interest in applications involving
autonomous vehicles and safe driving. There are other important applications such asassistive
technology for visually impaired pedestrians w he re traffic recognition is relevant. Crossing
streets and navigating in crowded environments like cities can b e very hard for the significant
segment of population that is
blind or visually impaired. In the past few years, several research
efforts were undertaken and papers published on regular traffic light detection. Some attempts
have been made to detect traffic light signals but a comprehensive method still has to b e
develop ed. The main goal of the work in this thesis was to develop technology to b e integrated
in a simple wearable device for
blind people to help them navigate outdoors to perform their
everyday life activities and in particular to cross streets safely. The problem of automated traffic
light in the absence of infrastructure is addressed. The proposed method examined various
alternatives and an algorithm was devised to detect traffic lights by first selecting possible
candidates by performing traffic light color extraction, pruning the large candidate set using
traffic light properties, next carrying out recognition and classification of lights before finally
making a decision on the traffic light signal. When tested on a set of image data, the algorithm
achieved go o d results with the estimated correct detection rate of the prototype determined
to b e above 90 %. The detection of pedestrian traffic signals indicating “walk and don't walk"
was also considered and the algorithm devised for this problem also yielde d go o d results, again
with an estimated correct detection rate better than 90 %

▼ The World Health Organisation estimates 36 million are blind worldwide; in addition, 217 million have severe or moderate visual impairment. Over the past decades, there has been substantial research in alleviating blindness and visual impairment. However, the blind community has yet to widely accept a single electronic travel aid (ETA) solution; the low cost white cane still remains the most popular device for orientation and mobility. One major limitation of current ETAs is their poor cost-benefit ratio. However, semiconductor advances may have reached a point where previous limitations are now surmountable as miniaturisation, flexible, low-cost and low-power circuits have been key enablers of wearable technology. Sonar has consistently been the preferred modality for single-sensor ETAs. The thesis aims to study performance characteristics of various beamforming aspects in their relation to developing a wearable-sonar system for blind aid applications. The scope of analysis covers 1)
Classical Beamfomers 2) Beamforming Augmentation (Geometry, Shading, Adaptive Algorithms) 3) Spherical (3D) Beamsteering and Conformal Arrays
Subjects/Keywords: beamforming; array; signal processing; acoustic; ultrasound; phased array; sonar; beamsteering; beamformers; delay and sum; adaptive; conformal; wearable; blind aid; ETA; rehabilitation

▼ Hearing aid devices are used to help people with hearing impairment. The number of people that requires hearingaid devices are possibly constant over the years, however the number of people that now have access to hearing aiddevices increasing rapidly. The hearing aid devices must be small, consume very little power, and be fairly accurate.Even though it is normally more important for the user that hearing impairment look good (are discrete). Once thehearing aid device prescribed to the user, she/he needs to train and adjust the device to compensate for the individualimpairment.We are within the framework of this project researching on hearing aid devices that can be trained by the hearingimpaired person her-/himself. This project is about finding suitable noise cancellation algorithm for the hearing-aiddevice. We consider several types of algorithms like, microphone array signal processing, Independent ComponentAnalysis (ICA) based on double microphone called Blind Source Separation (BSS) and DRNPE algorithm.We run this current and most sophisticated and robust algorithms in certain noise backgrounds like Cocktail noise,street, public places, train, babble situations to test the efficiency. The BSS algorithm was well in some situation andgave average results in some situations. Where one microphone gave steady results in all situations. The output isgood enough to listen targeted audio.The functionality and performance of the proposed algorithm is evaluated with different non-stationary noisebackgrounds. From the performance results it can be concluded that, by using the proposed algorithm we are able toreduce the noise to certain level. SNR, system delay, minimum error and audio perception are the vital parametersconsidered to evaluate the performance of algorithms. Based on these parameters an algorithm is suggested forheairng-aid.

▼ The objective of this research was to increase the independence and safety of the sight impaired by developing an enhanced travel
aid in the form of a sensor embedded long-cane to reduce the risk of injury from walking into suspended or overhanging objects while providing the sight impaired community with a familiar and well accepted tool.
Prior research at the Electromechanical Systems Laboratory had established a theoretical framework for ultrasound-based ranging and spatial obstacle localization from the moving reference frame of a long-cane. A prototype was implemented using analog threshold detection techniques.
This research focused on a new approach. A coded pulse was transmitted and correlation techniques were used to identify echoes and determine time of flight. Compared to the prior effort this new approach was more sensitive, had greater noise immunity, and provide greater spatial resolution for obstacle detection. The first step in the coded pulse approach was to generate a transmit pulse with an embedded binary code that is highly distinguishable. A transmit pulse generated by phase modulating a 40 kHz carrier signal with a 13-bit Barker code word, with each bit consisting of 4 cycles of the 40 kHz carrier was used. Digitized representative echoes were used as reference vectors for correlation to account for the effect of the impulse responses of the transducers, the air, and the reflection, on the transmitted pulse. In a detection cycle, the coded pulse was transmitted, the A/D converters took 2600 samples at the 150 kHz sampling rate to capture any echoes from objects between 1 and 4 meters in front of the cane. The receiver data was cross-correlated with the stored echo image to find echoes in the received signal. The correlation peak positions from the upper receiver were then compared to the peak positions from the lower receiver and if they collaborated within the synthetic aperture, the range and height were calculated annunciation was made by a synthesized voice.
The new obstacle detection system described above was designed and a prototype was constructed and embedded into the shaft of an 18 mm diameter body of a long cane.

▼ Information seeking on websites has become
more and more challenging for people who are
blind. Screen readers
attempt to make that task easier by introducing new commands and
functionality but there still exists a fundamental gap in the
difficulty for people who are
blind compared to their sighted
counterparts. This research identifies the strategies used by
people who are
blind and sighted to create an information seeking
model, develop the Keywords Expected for Your Search (KEYS)
conceptual model for assisting task performance and evaluate a KEYS
prototype of this concept for information search and
retrieval. This information seeking model was
developed by conducting an initial experiment and then validating
the model using data from a similar study. The model defines
information searching strategies used for both participants that
were sighted and
blind. Primary information search strategies for
the web were identified. The model demonstrated the primary search
strategies in the model were keyword based and are the foundation
for information seeking on websites for both groups of
participants. The KEYS conceptual model for
assisting task performance was developed. It includes rules and a
keyword library to support information searching for users who are
blind. A KEYS prototype was developed to test the conceptual model.
The prototype was implemented by controlling the results of the
list of links and virtual find commands, which are two of the more
commonly used primary search strategies for users who are
blind.
The evaluation sought to determine the aids' impact on workload,
number of commands used, search success, path direction and time to
complete a task. Comparisons of the participants who were
blind
with and without the KEYS prototype were made as well as
comparisons to sighted participants. Age group comparisons and age
of blindness onset were also compared. The
results of the experiment demonstrated that the KEYS prototype
significantly improved information searching for users who are
blind by lowering all measured variables. A
primary contribution of this research was to demonstrate that
providing keyword support improves information searches.
Implementing the KEYS can produce a significant difference in how
users who are
blind search for information on
webpages.

▼ The performance of outdoor positioning has become excellent with the emergence of Global Positioning System (GPS), but GPS is not reliable indoors. The ability of a system to perform indoor positioning without GPS is still challenging and has gained a lot of attention in recent years.
Indoor positioning has become a focus of research during the past decade. Despite a lot of research efforts, existing indoor positioning systems based on different technologies are still limited because most of them either require expensive infrastructure (ultrasound), offer limited coverage (Wi-Fi, Bluetooth) or provide low accuracy (audible sound). On the other hand, machine vision offers the potential for a cheap and effective solution for robust indoor positioning.
This thesis describes the research, experiments and analysis conducted to develop a machine vision based system, known as "Indoor Positioning System (iPoS)", which can provide reliable positioning in indoor environments. iPoS is based on a client server model where the client is a smartphone application and the server uses the proposed "BoWLocator" algorithm to match the incoming query image from the application. The key approach to the system is the use of minimum information i.e. a single image of a location from the phone camera for localisation. The main purpose of iPoS is to use it as a navigation
aid for
blind people and guide them while they move in unfamiliar indoor environments because they often feel lost in the absence of current location information.
To create a reliable indoor positioning, iPoS uses three proposed components (1) voting module, (2) homography verification method, and (3) post-verification method. iPoS has been demonstrated to localise on four realistic datasets covering a total of 50 indoor self-similar locations with a correct acceptance rate of 72-93% with few wrong matches depending on the test set and queries typically require 5-14 seconds on average to return a result. iPoS gives a very low localisation error with an average wrong match rate of 5.5%.

▼ Introduction: The maintenance of good oral hygiene among orthodontic patients is a challenge. The purpose of this study was to compare the oral hygiene habits, gingival health, and preference of orthodontic patients when using a floss
aid compared to conventional finger flossing with a floss threader. Methods: Thirty-four adolescent and young adult patients with fixed orthodontic appliances and poor oral hygiene were enrolled from the Loma Linda University Graduate Orthodontic Clinic. This was a single
blind crossover study. The patients were randomly assigned to one of two treatment groups (floss
aid or finger floss) in phase I. After prophylaxis, subjects were instructed to use the floss
aid or finger floss once a day and continue brushing for 4-5 weeks. Patients then had a washout period of 4-5 weeks. In phase II, patients were assigned to the alternate treatment group for another 4-5 weeks. Clinical measurements of gingival index (mGI), plaque index (mQPI) and full mouth bleeding score (FMBS) were recorded at baseline prior to prophylaxis and after 4-5 weeks of each treatment. A survey to assess oral hygiene habits and product preference was given at the end of each treatment and results were analyzed using the McNemar and McNemar-Bowker test. Statistical analysis for mGI, mQPI and FMBS was performed
using Paired Sample t-test and a mixed model procedure. Results: The Paired Sample t-test indicated no significant difference between baseline scores for mGI, mQPI and FMBS at phase I and phase II. The mixed model procedure analyzed data for the effects of time, treatment and treatment sequence on mGI, mQPI and FMBS. Results revealed statistically significant improvements in mGI, mQPI and FMBS for both treatment groups over time, with the floss
aid showing more improvement (P <0.05). Percent frequency of mGI and mQPI scores after treatment for test (floss
aid) and control (finger floss) groups showed improvements in both interproximal and middle regions of the teeth. Treatment sequence was not statistically significant for any of the indices. The McNemar test indicated a statistically significant difference in the time to complete flossing between the two treatment groups (P =0.002). After using both the test and control products, 85.3% of subjects preferred the test product. Conclusions: Both the floss
aid and conventional finger flossing were effective at reducing plaque, gingival inflammation and bleeding over time. Although the statistical analysis model showed more improvement in all indices with the floss
aid, the improvements were small and not clinically significant.

▼ This thesis explores the relationship between architecture and the
blind people. For better clarity and understanding of the topic, The work has been divided into five distinctive parts. In the first, introduction part, I approach space sensation of a
blind person from the physiological and psychological angle. This analysis is very important for the understanding of imagination, which the
blind person has. Another important fact to understand is the way in which the
blind person gets the information about the space and what is his ability to process it. Further, I explain the basic principles of the
blind person’s movement through space and describe instructions of how to help
blind people in the concrete spatial situations. In the next part, I give a short information about the historical progress of the relation between the society and the
blind people. An important fact is that, as late as 200 years ago, the
blind people were considered as “sub men” and did not have the full freedom privilege. This relation has been modified over time and nowadays, the
blind people have the freedom of movement and all the rights to enjoy their lives. To meet the needs of the
blind people, many associations have been created that act on their behalf. The associations have different modes of functioning, but their common goal is to help
blind people with their social rehabilitation, looking for employment and removing architectural barriers. The core of my work is divided into two parts. In the first one, I focus on the problematic of the
blind people and architecture from the functional aspect. The functional aspect is vital for the
blind people. It corresponds to their safety in the environment. In this chapter, I treat in detail basic elements for designing buildings, for specifying barriers and principles of design for
blind people. Furthermore, I describe the help tools the
blind people need in order to move in the space. I evaluate the future of these tools and indicate the rapid technological progression which makes the life of
blind people more comfortable. In the next part, I focus on the problematic of the
blind people and architecture from the aesthetic aspect. This question has not been much explored yet, but is, nonetheless, very important. In this part of my work, I use more my personal experience and the knowledge coming from the exploration of space. Aesthetical values are subjective for all the people, with or without a handicap. Therefore, in this final chapter, I try to note the facts that can be used in the process of the aesthetical perception and to reflect on them. In the domain of aesthetical research, there also exist tools and institutions that help
blind people in their comprehension of architecture. The division of my work emerged from the compilation of diverse facts in the process of writing. This thesis has an informative and practical character. It is intended for people who want to understand and to be informed about how to design architecture for the

▼ The need for assistive devices has, had and
will have a large merit in many engineering research arenas. This
dissertation deals with the design, modeling, implementation and
experimentation of the navigation component of a wearable assistive
system for
blind and visually impaired people, called TYFLOS
(ΤΥΦΛΟΣ) which is the Greek word for “Blind”. The
current prototype consists of two mini cameras attached to a pair
of conventional eye-glasses, a 2D tactile display vibration array)
which consists of 16 vibrating elements arranged in a 4x4 manner,
attached to an elastic vest worn on the user‟s abdomen, a portable
computer, an ear-speaker and a microphone. The
Tyflos Navigator is an Electronic Travel
Aid (ETA) with primary
goal to help users towards their independent mobility in indoor
environment. Its main sensor unit, the stereo vision system,
captures environmental information from the user's field-of-view.
3D representations are created and moving objects are identified
using stereoscopic vision and motion detection methodologies. The
high resolution output of the methodologies is projected on the low
resolution vibration array via a high-to-low methodology based on
navigation criteria and modeled with a formal language called
Vibration Array Language (VAL). The spatial distribution and
temporal characteristics (varying frequencies) of the vibrating
elements of the vibration array can inform the user for safe
navigation paths and obstacles, giving distance and location
information. All parts of the system will be
continuously adapted until the users' needs are fulfilled or the
technological constraints are reached. A step towards that goal
will be shown at the last part of this work with the development of
a tactile vocabulary and the experimentation with users where they
provide feedback giving us directions for refinements, changes and
future work.
