This client uses the joystick on his wheelchair as a cursor on the computer however he also needs a way to activate the right and left click features. His joystick is on the left side of the chair and the buttons would need to be mounted beside it on the chair.

Your task is to design some mouse buttons that can easily be mounted on a power chair and be easily activated. The device must be robust and securely mounted. It must be able to be installed and removed from the chair quickly. It must also be able to be cleaned. Ideally it would have both a bluetooth and usb option to connect to the computer but one is sufficient.
