Abstract
A motion sensing system includes a hand-held device and a receiver device. The hand-held device includes a microcontroller, a G-sensor (one 3-axis accelerometer), only one 2-axis gyroscope, and a wireless transmitter. The receiver device is preferably a dongle and includes a microcontroller and a wireless receiver. A first axis of the 2-axis gyroscope is parallel to the Z axis of the hand-held device and the second axis of the 2-axis gyroscope forms an acute angle α with the X axis of the hand-held device. The acute angle α allows the microcontroller of the receiver device to calculate rotational data around each of the three axis of the hand-held device.
