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. The device can switch modes based on a condition of the device, such as an expiration of a timer or a relative distance of an object from the panel.
