Claim:
1. A method for determining direction information for one or more wireless devices relative to eyewear by using a plurality of beamforming antennas, the method comprising: scanning, using a detection beam, at least a first radio frequency of multiple radio frequencies using at least a first beamforming antenna and a second beamforming antenna of the plurality of beamforming antennas that are mechanically integrated with, and communicatively coupled to, the eyewear; detecting, on the first scanned radio frequency, first externally emitted radio energy using the first and second beamforming antennas; identifying a first wireless device using the detected first externally emitted radio energy; and determining a first direction and estimated distance of the first wireless device relative to the eyewear based on a signal strength of the detected first externally emitted radio energy detected using the first and second beamforming antennas.
