Research into interaction techniques for on screen keyboards
Form many people with a physical disability, once they are unable to use a mouse or joystick (in the conventional manner) they are forced to use switches.
This is a rather slow and often frustrating input method (in some/many cases).
Apart from the addition of head and eye gaze systems, users had more input options in the 1980s!
Some people with a physical disability, e.g. muscular dystrophy, have poor gross motor movement but retain pretty good fine motor control. The goal of this work was to exploit this capability to provide them with better access.
The presentation discuss these issues and incorporated a live demo of On Screen Keyboards and alternative input devices with a PowerPoint presentation.
