Abstract
An electronic device includes a housing, one or more processors, and one or more proximity sensor components, each having an infrared signal receiver to receive an infrared emission from an object external to the housing. The proximity sensor component is disposed by a first aperture and a second aperture, the first aperture having a first axis oriented in a first direction and the second aperture having a second axis oriented in a second direction. Attenuation of infrared emissions can occur through one of the first aperture or the second aperture. The one or more processors can determine whether a received infrared emission is attenuated to detect whether the received infrared emission was received from the first direction or the second direction.
