A motion mapping system includes a motion sensing device and a receiving device. The motion sensing device may include an accelerometer, a rotational sensor, a microcontroller, and an RF transmitter. The microcontroller may output processed motion data to the receiving device. The receiving device may include an RF receiver, a microprocessor, and a Universal Serial Bus interface for connection to a computer. The receiving device's microprocessor may output the processed motion data to motion mapping software. The motion mapping software may map the motion data to a corresponding predetermined input event defined by the motion mapping software and transmit a control signal back to the receiving device's microprocessor indicating the corresponding predetermined input event. Upon reception of the control signal from the mapping software, the receiving device's microprocessor may generate a hardware input event according to the control signal and transmits the generated hardware input event back to the computer.
