Abstract
A Hall-effect system for providing inputs into a processor includes at least one magnet for establishing a magnetic field, a remote sensor unit and a receive station. The magnet is sized and adapted to be worn on a user's finger, while the remote sensor unit is adapted to be worn on a user's thumb. The remote sensor unit includes a Hall-effect sensor that senses changes in the magnetic field due to the motion of the magnet relative to the Hall-effect sensor. The Hall-effect sensor detects the magnetic field changes, and the remote sensor unit generates a sensor output corresponding to the magnetic field changes. The receive station is connected to the processor. The receive station receives the output from the remote sensor unit and converts the sensor output into an input for the processor.
