Abstract: An electronic device such as a pair of headphones may be provided with ear cups having speakers for playing audio to a user. Capacitive proximity sensor electrodes having acoustic openings may overlap the speakers. The capacitive proximity sensor electrodes may include electrodes that are arranged in a ring. Control circuitry in the electronic device may use the capacitive proximity sensor electrodes to measure ear patterns of a user when the headphones are being worn on the head of the user. The control circuitry may include switching circuitry that allows the electrodes to be dynamically combined to form electrodes of enlarged area to enhance detection range or to form separate electrodes to enhance spatial resolution.

Abstract: Embodiments are directed to a user input device and methods for expanding an input area in response to an estimation of the accuracy of touch input or the likelihood that a series of touches will hit an intended touch target area. In one aspect, an embodiment includes a first capacitive area defined by a first electrode and a second capacitive area defined by the first electrode and a second electrode. The embodiment further includes a processing unit that may be configured to, in a first mode, execute an operation in response to a touch received in the first capacitive area. The processing unit may be configured to, in a second mode, execute the operation in response to the touch received in the second capacitive area.
