Patent number: 10073518Abstract: An apparatus for calibrating an eye tracking system of a head mounted display displays a moving object in a scene visible through the head mounted display. The object is displayed progressively at a plurality of different points (P) at corresponding different times (T). While the object is at a first point of the plurality of different points in time, the apparatus determines whether an offset between the point P and an eye gaze point (E) satisfies a threshold. The eye-gaze point (E) corresponds to a point where a user is determined to be gazing by the eye tracking system. If the threshold is not satisfied, the apparatus performs a calibration of the eye tracking system when the object is at a second point of the plurality of different points in time. The apparatus then repeats the determining step when the object is at a third point of the plurality of different points in time.Type: GrantFiled: January 23, 2014Date of Patent: September 11, 2018Assignee: QUALCOMM IncorporatedInventors: Md Sazzadur Rahman, Kexi Liu, Martin H.

Publication number: 20160127460Abstract: A method is disclosed for discovering communication devices. The method includes broadcasting, with a first communication device, a message that can be detected by one-hop neighbors. The first communication device listens for data indicating that it has at least one two-hop neighbor, and constructs and stores a list of its one-hop and two-hop neighbors. In addition, the method may also include selecting a subset of the set of one-hop neighbors such that all of the two-hop neighbors of the first communication device can be reached by the first communication device through the subset of one-hop neighbors. Then the selected subset is stored on a list on the first communication device. Next, the first communication device broadcasts to one-hop neighbors in the selected subset, the data indicating that a one-hop neighbor is part of the selected subset. The method also allows the discovery of multi-hop neighbors by utilizing the selected subset.Type: ApplicationFiled: November 3, 2014Publication date: May 5, 2016Inventors: Gang Ding, Richard Oliver Farley, Md Sazzadur Rahman
