Abstract: Methods, systems and devices are provided for receiving input in a wearable electronic device from positioning an object near the wearable electronic device. Embodiments include an image sensor receiving an image. An input position of the object near the wearable electronic device may be determined with respect to a frame of reference. The determined input position may be one of a plurality of positions defined by a frame of reference and may be associated with an input value. A visual indication regarding the input value may be provided on a display of the wearable electronic device. At least one of an anatomical feature on the wearer and a received reference input on the anatomical surface may be used to determine the frame of reference.

Abstract: Techniques and systems described herein provide for improved clock drift calibration of two or more clocks of two or more wireless devices. According to one example method, a first packet is received at a first wireless device from a second wireless device sent at a first time. The method may also include determining a first time-of-arrival estimate for the first packet. The method may further include receiving, at the first wireless device, a second packet from the second wireless device sent at a second time. The method may also include determining a second time-of-arrival estimate for the second packet and determining a relative clock drift between the first wireless device and the second wireless device based at least in part on the first time-of-arrival estimate and the second time-of-arrival estimate.
