    摘要: A bias value associated with a sensor, e.g., a time-varying, non-zero value which is output from a sensor when it is motionless, is estimated using a ZRO-tracking filter which is a combination of a moving-average filter and a Kalman filter having at least one constraint enforced against at least one operating parameter of the Kalman filter. It achieves faster convergence on an estimated bias value and produces less estimate error after convergence. A resultant bias estimate may then be used to compensate the biased output of the sensor in, e.g., a 3D pointing device.

    摘要: Systems and methods according to the present invention describe 3D pointing devices which enhance usability by transforming sensed motion data from a first frame of reference (e.g., the body of the 3D pointing device) into a second frame of reference (e.g., a user's frame of reference). One exemplary embodiment of the present invention removes effects associated with a tilt orientation in which the 3D pointing device is held by a user.

    摘要: A 3D pointing device for use with a content delivery system is provided. The pointing device can operate in one of at least one of two modes: a first 3D or scrolling mode, and a second non-3D mode that can also be referred to as an up-down-left-right (UDLR) mode. The pointing device can include one or more directional sensors, to provide orientation and movement information. For either of the at least two modes, an optical finger navigation module is provided that can detect movement of a user's finger or object across its screen, and provides a predetermined threshold that must be exceeded before movement information is generated from the OFN module. The pointing device can generate scroll and UDLR commands based on the information from the orientation and movement sensors, as well as the OFN module, or can provide the information from the orientation and movement sensors to a user interface that can generate the appropriate scrolling or UDLR commands for use by the content delivery system.
