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.
