    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: 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.
