single switch control method – although this can become very complex and many wheel-
chair control systems are unlikely to support this well.
There are also examples of this integration mode in other devices – for example, some
individuals have used their eye-gaze-controlled communication aid to control a wheel-
chair (e.g., Eyedrivomatic and Rolltalk wheelchair controller ). In this mode, the com-

munication aid is the primary device and the wheelchair the secondary (see James’s Case
Study). The benefits and disadvantages of such system are listed in Table 10-3.

Example devices for wheelchair as base include BJoy Ring, RNET Bluetooth mouse
