On the back cover:

Recent developments in three-dimensional (3D) display and 3D input hardware have brought Virtual Reality (VR) within the reach of many scientists and engineers. Potentially, VR systems can improve the user experience of 3D data exploration in a Virtual Environment (VE).
However, the transfer of existing desktop application functionality to an interactive, 3D VE is not straightforward. Where mouse-based interaction dominates the view of graphical user interfaces on the desktop, 3D interaction in VEs is relatively unexplored and introduces new challenges.
These challenges of 3D interaction are discussed in the two parts of this thesis. The first part discusses issues of usability and proposes improvements of existing 3D Interaction techniques. In the second part, issues of design and development of software for 3D application and interaction techniques are discussed and an interactive development approach is proposed.
The results presented in this thesis contribute to the design and development process for improved 3D exploration environments and may also have wider application in other highly interactive systems.

Context

In a broad sense, this is a continuation of the work I did in 2002 during my final MSc project, "Interactive Visualization on the Virtual Reality Responsive Workbench (PDF). The official description of my PhD work, according to the bsik-brick project description states:"Investigate new interaction concepts, tools and scenarios, especially suitable for active-space virtual environments. The interaction consists of navigation, object selection and manipulation, and application control. Visual and physical feedback, and physically based simulation will be used to create natural and intuitive responses of the environment to user actions. The Virtual Workbench will be used as an environment for the interaction functionality." Here you can find the recent developments in the overall project.

Additional Material

Chapter 2 and 3: IntenSelect and Hybrid Interfaces: video 1 (avi, 3 MB), video 2 (avi, 5 MB).
- These videos illustrate the IntenSelect technique being used on the hybrid interface elements on the Virtual Workbench. The second video demonstrates the application of these techniques in the Cloudexplorer application.
Chapter 4: Consistent Multi-User Viewing and Interaction: video (WMV, 11 MB)
- This video demonstrates how two users share the use of the Virtual Workbench. Both users are headtracked and have a interaction stylus. A slider allows users to transfer the virtual camera and the correct visual perspective between the two users. The styli remain corrected for each user so they can still select and manipulate objects within the Virtual Environment.
Chapter 6: StateStream Model and Architecture: video (WMV, 28 MB)
- This video is a screencast from a StateStream session. It shows the visual front-end and the Virtual Environment (VE) as a small inset. The VE is controlled by special interaction tools. As the user interacts with objects, the visual front-end displays the changes in states and streams at run-time.
