Filed:

Oct 15, 2008

Appl. No.:

12/252322

Inventors:

DAVID SACHS - SUNNYVALE CA, US
STEVEN S. NASIRI - SARATOGA CA, US
JOSEPH JIANG - SAN JOSE CA, US
ANJIA GU - STANFORD CA, US

Assignee:

INVENSENSE - SUNNYVALE CA

International Classification:

G06F 3/01

US Classification:

715863

Abstract:

Mobile devices using motion gesture recognition. In one aspect, processing motion to control a portable electronic device includes receiving, on the device, sensed motion data derived from motion sensors of the device and based on device movement in space. The motion sensors include at least three rotational motion sensors and at least three accelerometers. A particular operating mode is determined to be active while the movement of the device occurs, the mode being one of multiple different operating modes of the device. Motion gesture(s) are recognized from the motion data from a set of motion gestures available for recognition in the active operating mode. Each of the different operating modes, when active, has a different set of gestures available. State(s) of the device are changed based on the recognized gestures, including changing output of a display screen on the device.

Appl. No.:

13/164747

Inventors:

Steve Nasiri - Saratoga CA, US
Joseph Jiang - Sunnyvale CA, US
Shang-Hung Lin - San Jose CA, US
Yuan Zheng - Fremont CA, US

Assignee:

INVENSENSE, INC. - Sunnyvale CA

International Classification:

G06F 3/033

US Classification:

345157

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.

International Classification:

H03K 17/94
H03M 11/00

US Classification:

341 20

Abstract:

Interfacing application programs and motion sensors of a device. In one aspect, a high-level command is received from an application program running on a motion sensing device, where the application program implements one of multiple different types of applications available for use on the device. The high-level command requests high-level information derived from the output of motion sensors of the device that include rotational motion sensors and linear motion sensors. The command is translated to cause low-level processing of motion sensor data output by the motion sensors, the low-level processing following requirements of the type of application and determining the high-level information in response to the command. The application program is ignorant of the low-level processing, and the high-level information is provided to the application program.
