For some people their joystick control is just about OK to drive a powered chair but not accurate enough to operate a computer or a communication aid - as a joystick. These people may like the joystick to behave as a discrete switch (say when pushing forward) or as a few discrete switches when not driving. They would then be able to operate switch-scanning programmes on a computer or a communication aid with the wheelchair's joystick.

Furthermore the wiseDX will enable infrared environmental control to be used (already built into the unit) with the joystick acting as a switch.
