Abstract: An electronic device may include a proximity sensor and a display. In particular, the display may be deactivated when the device is near a user's head. However, the proximity sensor may operate through or near the display and may detect the user's finger. Therefore, to distinguish between the user's finger and head, a motion sensor, such as an inertial measurement unit (IMU) may be used. For example, the position, acceleration, and rate of rotation of the device may be measured by the IMU, and a machine-learning algorithm may take the position, acceleration, and rate of rotation as inputs to determine whether the proximity sensor is triggered by the user's finger or head. In response to determining that the proximity has been triggered by the head, the display may be deactivated. Alternatively, in response to determining that the proximity sensor has been triggered by the finger, the display may remain on.

Abstract: An input device includes a keycap, a first electrode disposed to move in response to movement of the keycap, a planar array of electrodes extending at least partially under the keycap, and a sensor. The planar array of electrodes includes a second electrode, a third electrode, and a fourth electrode extending between the second electrode and the third electrode. The sensor is coupled to at least one of the second electrode or the third electrode and configured to generate a signal indicative of a change in capacitive coupling between the second electrode and the third electrode. The change in the capacitive coupling may result from movement of the first electrode.
