  • Patent number: 11112875
    Abstract: Methods and apparatus for gesture-based control of a device in a multi-user environment are described. The methods prioritize users or gestures based on a predetermined priority ruleset. A first-user-in-time ruleset prioritizes gestures based on when in time they were begun by a user in the camera FOV. An action-hierarchy ruleset prioritizes gestures based on the actions they correspond to, and the relative positions of those actions within an action hierarchy. A designated-master-user ruleset prioritizes gestures performed by an explicitly designated master user. Methods for designating a new master user and for providing gesture-control-related user feedback in a multi-user environment are also described.

  • Patent number: 11106312
    Abstract: A method of predicting the behaviour of one or more objects on a touch surface of a touch-sensitive apparatus comprises outputting an object position value of a first time series describing a position of the one or more objects on the touch surface. The method further comprises outputting an object position value of a second time series describing a position of the one or more objects on the touch surface. The object position value of the second time series is outputted before the corresponding object position value of the first time series. The method yet further comprises predicting the behaviour of the one or more objects based at least on the object position values of the second time series.

  • Patent number: 11099677
    Abstract: Embodiments of the disclosure relate to touch display devices. The difference in parasitic capacitance due to the difference in length between the touch routing lines may be reduced by separately arranging touch electrode lines in the active area and connecting the touch routing line connected with each portion of a touch electrode line with the touch routing line connected with each portion of another touch electrode line. Therefore, it is possible to reduce loads and the differences in touch sensing depending on the connection structure and position of the touch routing line by driving the touch electrode line in a double-routing structure. By so doing, the performance of touch sensing may be enhanced.
