Abstract
A method performed by an apparatus includes scanning at least one of multiple radio frequencies using at least two beamforming antennas of a plurality of beamforming antennas coupled to the eyewear and detecting, on a first scanned radio frequency, first externally emitted radio energy. The method further includes identifying a first wireless device using the detected first externally emitted radio energy and determining a first direction of the first wireless device relative to the eyewear.
