BBBeat

BBBeat is an audio game designed for the visually impaired. As such it has no video display. The player wears a pair of headphones and must use sound to locate a bee and then swat it. Sensors attached to the wrist indicate whether or not the "bee" was swatted. The game was developed by Makato Ohuchi at Tohoku Fukushi University in Japan.

The game is designed for schools and rehabilitation centers for blind people, to assist with sound location and learning to navigate base on sound source, not for personal entertainment. The game requires extensive hardware, and is expected to cost in the thousands of US dollars.
