—We present an empirical usability experiment studying the relative strengths and weaknesses of three different occlusion management techniques for discovering and accessing obje...
User-to-User Communication within Internet-based 3D Virtual Environments is usually difficult mainly due to the trade-off between the capability and the complexity of the interface...
We present a new approach for enhancing local scene contrast by unsharp masking over arbitrary surfaces under any form of illumination. Our adaptation of a well-known 2D technique...
The most common technique for resizing 3D objects in virtual environments is the use of 3D widgets. However, such techniques often exhibit usability problems due to difficulties i...
We present a task-based taxonomy of navigation techniques for 3D virtual environments, used to categorize existing techniques, drive exploration of the design space, and inspire n...
