HIGH FIDELITY REMOTE CONTOLLER DEVICE FOR DIGITAL LIVING ROOM
First Claim
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 first three-axis motion sensor and the second three-axis motion sensor are encompassed on a single module.

Abstract
Described herein is an intelligent remote controlling device. The device can include a six-axis motion sensor to accurately track three dimensional hand motions. For example, the sensors can include a three-axis accelerometer and a three-axis gyroscope. The remote control device can also include a processing unit integrated with the motion sensors in a single module. The processing unit can convert data regarding the hand motion to data regarding a cursor motion for a cursor that will be displayed on a screen of an electronic device. The processing unit can be integrated with the motion sensors in a single module. The processing unit can include at least two modes of functionality corresponding to different types of hand motion: a one to one mode where the cursor directly tracks the hand motion and a non-linear mode that filters data from the motion sensors to eliminate hand jitter.
