Switch access to technology - A comprehensive Guide.

By Simon Judge and David Colven


When most of us use a computer we use the standard interface of a keyboard and mouse. However, what do you do if you cannot use a keyboard or mouse? A number of alternative access systems exist, for example: alternative keyboards, tracker balls, touchscreens, head pointers etc. But for some people these devices are also an impossibility, and this is where switches 'kick in'. The main subject of this document is the switch user. For completeness we have include a brief mention of other input devices, which may be grouped together as 'alternative access systems'.We aim to: - Encourage developers to include switch access into their products - Standardise practice and terminology. This document explains some of the issues involved for people with severe physical difficulties who access computers and other electronic devices with switches. It details the ways in which switch users interact with computer programs and other technology designed to be directly accessible to them. The document includes some precise definitions of terms. It also attempts to survey the whole range of issues associated with switch use. As such it should be useful to professionals working or entering the field, those software developers considering switch users for the first time and also for those already developing in this area
