Problems:
• The process of setting up a customised mounting cradle was a complex, timely
process and the mounting caused problems with wheelchair stability.
• Speakers were difficult to mount due to bulk, but were attached with Velcro to the
side of the chair.
Case 2
No client background.
This laptop system provides a means of communication and is also used for schoolwork
eg: written work. The computer is on for most of the day allowing for both response and
initiation of conversation. The wheelchair joystick is used to access the computer, using a
customised system. Using a switch the joystick can be toggled between computer and
driving mode. The computer screen needs to be lowered by an attendant to allow visibility
when driving. This means the lid is left slightly ajar to be able to see clearly when driving
but also to “speak” readily if required.
