Abstract
Abstract A hand-held controller employing inertial sensors is proposed for controlling toys, computers and other equipments requiring accurate steering signals. The use of inertial sensors (accelerometers and gyroscopic devices ) means that the angular and lateral movement of the hand-held controller in space provides the control signals and allows a large number of separate parameters to be varied simultaneously by one hand.
