Abstract :
In order to test the viability of the wheelchair aerobic fitness trainer (WAFT) as an interface for motivational video games, a simple computer game was developed. The game ran on a PC computer running ASYST software. Two signals were provided from each set of rollers of the WAFT. One was proportional to wheel velocity, and the other indicated direction (forward or reverse). These signals were sampled at 20 Hz and used to calculate position of an image on the computer screen. The object of the game was to drive the image around a track in the least amount of time. The results demonstrated the effectiveness of WAFT. The motion of the images was very easily controlled even by first time users with no wheelchair experience
