The Oregon Research Institute (ORI) has available free software for use in training children (and adults) with multiple or severe orthopedic disabilities in use of a power wheelchair. All they ask in return is for you to keep data (on children between 5 and 21) and share it with them. The software can be used with a specialized computer joystick, an unadapted gaming joystick, a gaming joystick adapted using the free JoytoSwitch software from One Switch.
