X-Max Game Controller
The Need:
The client has cerebral palsy which inhibits his motor skills to the point where it is impossible for him to play video games, specifically Xbox, using traditional control systems. Our controller aims to enable him to play X-Box with minimal external assistance.
The Solution:
Our current solution is an array of mechanical switches suspended around Max’s head which allow him to control 4 of the 10 buttons on a traditional Xbox controller. The switches are covered with large foam pads to enable comfortable head operation. The recent update includes an inline companion controller so that an occupational therapist or friend can play the game with Max and aid him as he learns to use the device. We have currently also been working on myoelectric controls and updating it into the prototype. Also, a preliminary concept involved an off-the-shelf joystick. The movement of a comfortable pad would be translated to a joystick input through a sliding physical connection. A spring is used to help re-center the pad: the spring is unstretched in the neutral (centered) pad position and applies a tensile force between the sliding contacts when stretched (Pad is moved). This design promotes simplicity using purchased parts.
