1. Skopik, Amy Caroline. Improving memorability in fisheye views.

Degree: 2004, University of Saskatchewan

Interactive fisheye views use distortion to show both local detail and global context in the same display space. Although fisheyes allow the presentation and inspection of large data sets, the distortion effects can cause problems for users. One such problem is lack of memorability – the ability to find and go back to objects and features in the data. This thesis examines the possibility of improving the memorability of fisheye views by adding historical information to the visualization. The historical information is added visually through visit wear, an extension of the concepts of edit wear and read wear. This will answer the question “Where have I been?” through visual instead of cognitive processing by overlaying new visual information on the data to indicate a user’s recent interaction history. This thesis describes general principles of visibility in a space that is distorted by a fisheye lens and defines some parameters of the design space of visit wear. Finally, a test system that applied the principles was evaluated, and showed that adding visit wear to a fisheye system improved the memorability of the information space. Advisors/Committee Members: Gutwin, Carl, Saucier, Deborah M., Kusalik, Anthony J. (Tony), Schneider, Kevin.

2. Schafer, Wendy Ann. Supporting Spatial Collaboration: An Investigation of Viewpoint Constraint and Awareness Techniques.

Degree: PhD, Computer Science, 2004, Virginia Tech

Spatial collaboration refers to collaboration activities involving physical space. It occurs every day as people work together to solve spatial problems, such as rearranging furniture or communicating about an environmental issue. In this work, we investigate how to support spatial collaboration when the collaborators are not colocated. We propose using shared, interactive representations of the space to support distributed, spatial collaboration. Our study examines viewpoint constraint techniques, which determine how the collaborators individually view the representation, and awareness techniques, which enable the collaborators to maintain an understanding of each other's work efforts. Our work consists of four phases, in which we explore a design space for interactive representations and examine the effects of different viewpoint constraint and awareness techniques. We consider situations where the collaborators use the same viewpoints, different viewpoints, and have a choice in viewpoint constraint techniques. In phase 1, we examine current technological support for spatial collaboration and designed two early prototypes. Phase 2 compares various two-dimensional map techniques, with the collaborators using identical techniques. Phase 3 focuses on three-dimensional virtual environment techniques, comparing similar and different frames of reference. The final phase reuses the favorable techniques from the previous studies and presents a novel prototype that combines both two-dimensional and three-dimensional representations. Each phase of this research is limited to synchronous communication activities and non-professional users working together on everyday tasks. Our findings highlight the advantages and disadvantages of the different techniques for spatial collaboration solutions. Also, having conducted multiple evaluations of spatial collaboration prototypes, we offer a common set of lessons with respect to distributed, spatial collaboration activities. This research also highlights the need for continued study to improve on the techniques evaluated and to consider additional spatial collaboration activities.
