  • Patent number: 11126315
    Abstract: A touch electrode layer and a touch display device are provided. By setting first and second electrodes of a touch electrode unit to a trunk and a branch structure, respectively. First electrode branches are electrically connected to first electrode trunks. Second electrode branches are electrically connected to second electrode trunks. The first electrode branches and the second electrode branches form “a homocentric squares pattern” of a limit coupling shape, which can increase rate of change of a basic mutual capacitance value when a finger touches it. In addition, third electrodes having “a homocentric squares pattern” are disposed between the first branch electrodes having a homocentric squares pattern and the second branch electrodes having a homocentric squares pattern and are not connected to the first branch electrodes and the second branch electrodes. This effectively reduces a basic mutual capacitance value Cm and can effectively reduce parasitic capacitance to ground.

  • Patent number: 11086406
    Abstract: A hand interaction system can use a three-state model to differentiate between normal hand movements, such as reaching for an object, and hand input gestures. The three-state model can specify a sequence of states including: 1) a neutral state, 2) a tracking state, and 3) an active state. In the neutral state, the hand interaction system monitors for a gesture signaling a transition to the tracking state but does not otherwise interpret a gesture corresponding to the active state as input. Once a gesture causes a transition to the intermediate tracking state, the hand interaction system can recognize a further active state transition gesture, allowing active state interaction. Thus, the monitoring for the intermediate tracking state provides a gating mechanism, making it less likely that the hand interaction system will interpret hand movements as input when not so intended by the user.
