Patent ID: 7821494

Claim:
An inertial mouse, comprising: a housing; a circuit substrate enclosed within the housing; a first accelerometer, coupled to a micro-controller and the circuit substrate, for measuring a first linear movement along a first axis and for measuring a first rotational movement around a second axis, and transmitting information corresponding to said measured first linear movement and said measured first rotational movement to the micro-controller; an auxiliary accelerometer, coupled to the micro-controller and the circuit substrate, for measuring a second linear movement along the first axis, wherein said auxiliary accelerometer is distanced away from said first accelerometer by a first distance, and transmitting information corresponding to said measured second linear movement to the micro-controller; a second accelerometer, coupled to the micro-controller and the circuit substrate, for measuring a third linear movement along said second axis and for measuring a second rotational movement around said first axis, and transmitting information corresponding to said measured third linear movement and said measured second rotational movement to the micro-controller; and the micro-controller, coupled to the circuit substrate, for calculating a rotational movement value reflecting movement on around a third axis based on the magnitude of said first linear movement, the magnitude of said second linear movement, and the magnitude of said first distance, and transmitting said rotational movement value to an electronic device to effect movement of a display cursor.
