  • Publication number: 20160259474
    Abstract: Touch and hover switching is disclosed. A touch and hover sensing device can switch between a touch mode and a hover mode. During a touch mode, the device can be switched to sense one or more objects touching the device. During a hover mode, the device can be switched to sense one or more objects hovering over the device. The device can include a panel having multiple sensors for sensing a touching object and/or a hovering object and a touch and hover control system for switching the device between the touch and hover modes. The device's touch and hover control system can include a touch sensing circuit for coupling to the sensors to measure a capacitance indicative of a touching object during the touch mode, a hover sensing circuit for coupling to the sensors to measure a capacitance indicative of a hovering object during the hover mode, and a switching mechanism for switching the sensors to couple to either the touch sensing circuit or the hover sensing circuit.

  • Publication number: 20150338964
    Abstract: Detecting a signal from a touch and hover sensing device, in which the signal can be indicative of concurrent touch events and/or hover events, is disclosed. A touch event can indicate an object touching the device. A hover event can indicate an object hovering over the device. The touch and hover sensing device can ensure that a desired hover event is not masked by an incidental touch event, e.g., a hand holding the device, by compensating for the touch event in the detected signal that represents both events. Conversely, when both a hover event and a touch event are desired, the touch and hover sensing device can ensure that both events are detected by adjusting the device sensors and/or the detected signal. The touch and hover sensing device can also detect concurrent hover events by identifying multiple peaks in the detected signal, each peak corresponding to a position of a hovering object.
