Abstract
Embodiments of the invention are directed to control devices configured for use with computing devices. More specifically, the present invention relates to methods and devices for performing presence detection of an object body near a device. The methods and devices described herein may include comparing a reference signal against an over the air signal to determine whether a phase difference exists between the reference signal and the over the air signal. The existence of a phase difference may be indicative of a object or body in proximity to the device.
