Cerebral Palsy and Adaptive Technology

I have a new student who has cerebral palsy.  He is unable to use a computer mouse to do programs on the computer.  Our school has an adaptive switch for him to use; however, no internet program such as stafall.com, works with the adaptive switch.  The only program I have found that works involves him hitting the switch and a ball kicks into the goal.  Obviously, this is not educational and is serving no purpose for him expect mere enjoyment.  Does anyone know of any good adaptive equipment for a child with cerebral palsy that works with internet sites?  Does anyone know of any good programs that work with an adaptive switch?
