At present, to run VE applications we have been developing in our laboratory, we use PC (dual Celeron/400 MHz and accelerated graphics card Matrox G400) with Linux. Visualization part including stereo uses OpenGL. With this configuration we achieve average speed 20fps in stereo display mode of the scene with 8000 triangles.
For interaction experiments we have used following hardware. Polhemus was used to track the position and orientation of user's hands. 5th Data Glove enabled to detect fingers motion. Original glove sensor was replaced by Polhemus sensor to get more precise data of hand orientation. Polhemus sensor was used to control origin of selection ray. Ray direction was derived from the direction of index finger on the right glove.
Currently we have connected left and right glove and we may test more complex manipulation techniques in future. Crystal EYEs were used for visual feedback. They provide smooth and natural depth view into scene.
Typical VR session is shown in Figure 10.
