Patent number: 8704766Abstract: Methods for processing information transmitted from a pointing device with at least one button towards a graphical interface operating according to received display motion coordinates and notifications are provided. A method includes intercepting sensed motion coordinates and the button status transmitted from the pointing device. The method further includes determining the display motion coordinates and the notifications based on an evolution of the sensed coordinates and an evolution of the button status, to remove an unintentional motion included in the sensed motion coordinates. The method then includes outputting the display motion coordinates and the notifications towards the graphical interface.Type: GrantFiled: October 28, 2011Date of Patent: April 22, 2014Assignee: Hillcrest Laboratories, Inc.Inventors: Matthew G. Liberty, Bryan A. Cook, Pouyan Amirshahi

Publication number: 20140078059Abstract: 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.Type: ApplicationFiled: November 26, 2013Publication date: March 20, 2014Applicant: Hillcrest Laboratories, Inc.Inventor: Matthew G.

Patent number: 8649999Abstract: 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.Type: GrantFiled: December 27, 2010Date of Patent: February 11, 2014Assignee: Hillcrest Laboratories, Inc.Inventors: Hua Sheng, Bryan A.

Publication number: 20140020028Abstract: A method of returning target scenes from a user link request is disclosed. The method comprises the steps of: receiving a user link request on a user interface; comparing the received user link request to a plurality of entries in a lookup table; for each entry in the plurality of entries in the lookup table that matches the received user link request, identifying a target scene that corresponds to the matched entry in the lookup table; determining a closest one of the target scenes if multiple entries in the lookup table match the user link request; and transitioning to the closest target scene.Type: ApplicationFiled: September 17, 2013Publication date: January 16, 2014Applicant: Hillcrest Laboratories, Inc.Inventor: Scott Anthony STANCHFIELD

Patent number: 8601396Abstract: Systems and methods according to the present invention provide a control framework for organizing, selecting and launching media items including graphical user interfaces coupled with an optional 3D control device for collection of the basic control primitives of point, click, scroll, hover and zoom which permit for easy and rapid selection of media items, e.g., movies, songs etc., from large or small collections. The remote control maps natural hand movements and gestures into relevant commands while the graphical display uses images, zooming for increased/decreased levels of detail and continuity of GUI objects to provide easy organization, selection and navigation among the media items by a user.Type: GrantFiled: January 30, 2004Date of Patent: December 3, 2013Assignee: Hillcrest Laboratories, Inc.Inventors: Frank A.

Patent number: 8581841Abstract: 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.Type: GrantFiled: January 15, 2013Date of Patent: November 12, 2013Assignee: Hillcrest Laboratories, Inc.Inventors: Daniel S.

Publication number: 20130245984Abstract: Apparatuses and methods calibrate attitude dependent magnetometer alignment parameters of a magnetometer mounted together with other angular position sensors on a device without prior knowledge of the local magnetic field and allowing a constant but unknown offset of the yaw angle in the reference attitudes with respect to an earth-fixed coordinate system. The method includes acquiring magnetic field measurements from the magnetometer and corresponding estimated angular positions subject to an unknown yaw offset relative to a gravitational reference system. The method further includes iteratively computing a scale and vector components of a quaternion representing a misalignment matrix, an inclination angle of local magnetic field, and a yaw angle offset, using an extended Kalman filter (EKF) infrastructure with a specific designed model and constraints, based on the magnetic field measurements and the corresponding estimated angular positions.Type: ApplicationFiled: November 17, 2011Publication date: September 19, 2013Applicant: Hillcrest Laboratories, Inc.Inventor: Hua Sheng
