This prevents him from controlling his electric wheelchair, but it didn't prevent him from teaming up with two other people (one also a quadriplegic) to design a way around the limitation. Eyegaze hardware is what lets people speak through a computer using only their eyes. Eyedrivomatic is an open source project that uses common materials to connect the Eyegaze to the joystick of the wheelchair without altering the chair (which is rented equipment in most cases). A 3D-printed gimbal is strapped over the existing joystick, but does not prevent it from still being used normally by caregivers. The gimbal's servo motors actuate the joystick with commands from the Eyegaze.
