iBeacons techniques
» Trilateration in theory can obtain exact location from 3 distances from known locations. http://upload.wikimedia.org/wikipedia/commons/6/6f/Trilateration.png
» Tripwires – used to identify movement between key areas and provide relevant proximity-aware content. Passed Lunchroom tripwire, highlight lunchroom on map.
» Nearables – finding and gathering content about specific nearby objects, e.g. printer, stationary cupboard, where is Nick?
