Abstract

Display devices including motion sensing and processing. In one aspect, a handheld electronic device includes a subsystem providing display capability and a set of motion sensors provided on a single substrate and including at least one gyroscope sensing rotational rate of the device around three axes of the device and at least one accelerometer sensing gravity and linear acceleration of the device along these axes. A computation unit is 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 axes and the sensed gravity and linear acceleration along at least one of the axes. The motion data describes movement of the device including a rotation of the device around at least one of the axes, the rotation causing interaction with the device.
