The computer game controller is an adaptable solution for somebody who can not use a keyboard and mouse comfortably. The user can control the computer by simulating keyboard presses and mouse clicks by pressing large buttons and using a joystick. These interfaces are more user friendly for somebody with low arm mobility.
Given the large number of keys needed to play a game properly and the limited space on the armchair a solution was to set up nine select-able keys displayed on a screen where a joystick controls which button is highlighted, when the user presses an action button the key that is highlighted will be pressed on the computer.
The controller's display first shows a menu screen where nine different profiles can be selected. These profiles hold different key presses for the game and other special features. For example Alien requires the left and right mouse buttons to be held together, this is done using one of the nine keys on the display.

- Wireless control from wheelchair to the computer
