For many people with a physical disability, switch control of an on-screen keyboard is the default solution for computer access. The work described here explores how people with a very limited range of movement, but with strong skills in both small movements and the timing of those movements (e.g. Muscular Dystrophy in its later stages), can control a computer using means other than switches.
Some of this work has come out of a visit to a school and hospital in northern Japan where there are over 100 people with muscular dystrophy from young people to some over 40 years old. The work is being fed into a number of products from Claro Software including OSKA, a new on-screen keyboard system which is currently working in both English and Japanese.
