I have always used IBM compatible computers, on my wheel chair. They run from batteries under the wheel chair, although an internal battery will keep the computer running for an hour if necessary. The screen is mounted on the arm of the wheel chair where I can see it, more recent systems have the whole computer in a box on this arm. The original systems were put together for me by David Mason, of Cambridge Adaptive Communications. This company manufacture and supply a variety of products to help people with communication problems express themselves.

On the computer, I run a program called Equalizer?, written by a company called Words Plus inc. A cursor moves across the upper part of the screen. I can stop it by pressing a switch in my hand.
