last year showed growing interest in using modern tool to make interaction with computer more natural. Different approaches are used to do this. for example, Herbelin, Cigar and Brooks [1] built various interfaces for disabled people to give them possibility to play the game Planet Penguin racer. they made possible to control the game with the use of one of three motion sensing devices (a camera, a sound beam ultrasonic distance sensor, and three-axis accelerometers). A commercial Silver fit system [2], in which a motion-sensing camera is used to acquire action of human who plays one of several built-in games, is available since January 2009. the system is targeted at old people after stroke and their therapists, and it serves as a rehabilitation tool. the Aurora project studies whether and how robots can become a toy that might play an educational or therapeutic role for children with autism [3]. recently, gesture-based interfaces are starting to appear in computer games [4]. review of the use of modern technologies to support disabled people can be found in online proceedings of international conference series on disability, Virtual reality and Associated technologies (ICDVRAT).
