Patent ID: 7907838

Claim:
A handheld electronic device, the device comprising: a set of motion sensors provided on a single sensor wafer, the motion sensors including at least one gyroscope sensing rotational rate of the device around at least three axes of the device and at least one accelerometer sensing gravity and linear acceleration of the device along the at least three axes of the device; memory for storing sensor data derived from the at least one gyroscope and the at least one accelerometer; and a computation unit capable of determining motion data from the sensor data stored in the memory, the motion data derived from a combination of the sensed rotational rate around at least one of the three axes and the sensed gravity and linear acceleration along at least one of the three axes, wherein the memory and the computation unit are provided on an electronics wafer positioned vertically with respect to the sensor wafer and substantially parallel to the sensor wafer, the electronics wafer being vertically bonded to and electrically connected to the sensor wafer, and wherein the motion data describes movement of the device including a rotation of the device around at least one of the three axes of the device, the rotation causing interaction with the device.
