Questions & Answers

Q: How does the multi-user virtual reality projection system work?

The system uses a large screen and camera-like glasses to display a 3D scene for up to six users, providing individual perspectives. The users' movements are tracked, allowing for accurate pointing and tracing gestures.

Q: How does the system improve the viewing experience in comparison to traditional VR systems?

In traditional VR systems, only one user's perspective is tracked, leading to distorted views for other users. However, in the multi-user system, each user has their own individual perspective, leading to a more immersive and shared experience.

Q: What technology is used to enable precise pointing and tracing gestures?

The system utilizes high-frequency projectors running at 360 Hz to display images for different users. This allows users to accurately understand and interpret each other's pointing and tracing gestures.

Q: Can the system be used for remote communication?

Yes, the system allows groups of people at different locations to meet in a virtual environment. Real-time 3D video avatars can be created using multiple perspectives from Kinect cameras, enabling face-to-face interactions.
