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.
