POINTING DEVICE

摘要

A gyroscopic pointing apparatus for an electronic device, particularly a games console, that is provided with means to detect when the mobile component is pointing at the screen upon which it controls a cursor to provide a mechanism to correct for drift in gyroscope readings and an improved method of dynamically recalibrating the zero point of the gyroscopes. The pointing detection mechanism may be provided by the combination of an infra-red LED and an infra-red sensor in either permutation on the mobile component and fixed component respectively.
