Abstract:
1. A handheld electronic device, the device comprising: a subsystem providing display capability; a set of motion sensors provided on a single sensor wafer substrate, the set of motion sensors for sensing rotational rate around at least three axes and linear acceleration along at least three axes, wherein the motion sensors sensing rotational rate are gyroscopes and the motion sensors sensing linear acceleration are accelerometers; memory for storing sensor data derived from the gyroscopes and the accelerometers; and a computation unit capable of determining motion data from the sensor data stored in the memory, wherein the memory and the computation unit are provided on an electronics wafer positioned vertically with respect to the sensor wafer substrate and substantially parallel to the sensor wafer substrate, the motion derived from a combination of the sensed rotational rate around at least one of the three axes and the sensed gravity and linear accelerator along at least one of the three axes, the electronics wafer being vertically bonded to and electrically connected to the sensor wafer substrate.
