Head-mounted mouse design using accelerometers.
John George Albrecht, M. Woodman · Digital WPI · 2003
The goal of this project is to create a computer mouse that can be used by a person who lacks use of their extremities. An accelerometer is used to measure the head tilt. When a 30-degree tilt is detected, the mouse cursor begins to move across the screen in that direction and continues to do so until the head moves upright again. The entire design was completed with a network of comparators with a microprocessor as the data interpreter.
