This is a computer version that lets you set the speed of play and the size of objects on the screen, and even offers voice-recognition control of the player's bat.

Aimed at very young children who can't move independently, this scooter is steered via a sensitive control jack mounted prominently on the front of the board.
Kids can use their chin or their feet to steer, depending on their position.
The scooter can carry kids weighing up to 95 pounds in a slow straight line or in circles along carpets or hard floors, lying on their bellies or on a special seat. The design even allows riders to wear braces or other physical aids. This software game built from a three-dimensional perspective provides simulation training for a power wheelchair.
