Abstract:
1. A handheld electronic device, the device comprising: three linear accelerometers and three gyroscope sensors provided on a single sensor wafer, the three gyroscopes sensing rotational rate of the device around at least three axes of the device and the three accelerometers sensing gravity and linear acceleration of the device along the at least three axes of the device; and memory for storing sensor data derived from the three gyroscopes and the three accelerometers, 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 sensor 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.
