Researchers develop High-Speed Virtual Table Tennis Game

Virtual Reality systems can perform at slow and medium speeds that make the humans interacting with the game feel that they are in a virtual environment.

Scientists Stephan Rusdorf, Guido Brunnett, Mario Lorenz and Tobias Winkler from the Chemnitz University of Technology in Germany wanted to test the limits of a virtual environment using no more than standard hardware components. There aim was to create a system that can make the humans forget that they are in a virtual environment.

For the setup they used no more than a standard PC with an up to date graphics card that can run two LCD beamers. They attached polarization filters in front of the beamers. These beamers project the image from behind onto an acryl screen.

The human counterpart stands in front of the screen and wears polarization glasses and paddle. Both of them have sensors that can track the movements of the human and the paddle. The information is then sent to a software program that determines the exact movement of the human.

The scientists found out that the system can determine precise movements from the information that is fed into the computer.

The competing humanoid avatar is also human like and it can adjust its own difficulty level by comparing that with the human.

This technology can be used for playing some more games and also in simulated tests. The virtual reality system developed by these scientists is so good that the humans try to keep the paddle onto the virtual table after completing the game.

Moreover the system is so fast to respond that it can respond to high ball speeds that are of the order of 15-meters per second.
