central nervous system that control voluntary muscle movement. The
disorder causes muscle weakness and atrophy throughout the body.” He writes and speaks using the software Equalizer, which he operates via a single button. It uses an

In order to continue to be able to function should his outdated
hardware fail, he approached some software companies, requesting that they

company that Vickram Crishna and I started, was happy to take up this

problem with Equalizer should never reoccur.
The importance of such software in the life of a disabled person can hardly be overstated. Indeed, Professor Hawking himself is the best example of this. He has been able to become not only one of our leading scientists, but also an immensely successful author and motivator, only because software allows him to write and to speak. Who knows how much genius we have left undiscovered, ...
