Controls on mobility scooter
The control difficulty was solved by interchanging the left and right hand functions. The inability to look to the left and the right was solved by installing a small TV monitor above the handlebars (but facing the rider at all times) and a camera, which rotated in sympathy with the handlebars. Power was derived from the scooter batteries.
The client is now able to use the scooter because the controls had been reconfigured and because she could look to left and right by appropriately rotating the handlebars.
