Abstract

The present disclosure describes a method and apparatus that can be used to determine whether an object is in proximity of an electronic device. When an object is not in proximity to the electronic device, the arrangement of two sensors at different distances from the optical emitter results in a higher strength of a reflection signal received in the sensor closer to the optical emitter and a lower strength of a reflection signal received in the sensor further from the optical emitter. The system uses this difference in reflection signals to calculate a ratio between the signals that are being reflected to both sensors, and based on the ratio whether an object is in proximity to the electronic device.
