Abstract:
1. A remote control device, comprising: at least one button configured to input a gesture motion or a handwriting motion; a first three-axis motion sensor that senses a rotational rate of the remote control device related to the gesture motion or the handwriting motion; a second three-axis motion sensor that senses gravity and linear acceleration of the remote control device related to the gesture motion or the handwriting motion; a processing unit configured to receive three-dimensional sensor data from the first three-axis motion sensor and the second three-axis motion sensor regarding the hand motion and to convert the sensor data to a device orientation, a cursor motion derived from an orientation change of the device, or a gesture command; and a radio frequency (RF) unit configured to transmit the device orientation, the cursor motion derived from the orientation change of the device, or the gesture command to an electronic device, wherein the processing unit, the first three-axis motion sensor and the second three-axis motion sensor are integrated in a single integrated circuit chip; wherein the processing unit calculates a three dimensional orientation corresponding to a hand motion with a high accuracy.
