This child has severe cerebral palsy. His only method of communication was through a speech synthesising computer and he needed the next level of computer to continue progress but this was unable to be mounted on his powered wheelchair.
An aluminium tube was mounted on the lower left side of the wheelchair with provision for adjusting its angle. The computer was mounted on an L-shaped steel tube which slid into the tube and an adjustable collar on the tube locked into a slot on top of the tube. This locking action stops the tube from rotating and the computer can be put in the correct position by adjusting the collar height and angle of the tube.
The boy can now learn to use a very sophisticated computer to communicate and it can be easily removed when necessary.
