The wiseDX may be suitable for people who can use switches and want to drive a powered chair in the most effective way that their abilities allow. They may use a single switch. They may use two or more switches. They maybe have good control over one or two switches but be able to operate another switch 'with some effort'.

Such people may want to operate a communication aid or other equipment with the same switch or switches through the wiseDX (it has a built in infrared transmitter). It could be that the wiseDX is only required as a 'special controls for driving' device and that operating other equipment with the same switch is not necessary or has not yet been considered.

If such integration was required, it could take place at a later date once driving skills had been mastered.
