Indoor Positioning Techniques in 2014: Where Are They Now?
The geolocation capabilities of smartphones are fantastic and well documented, so if your project requires you to locate people outside, you’re pretty well covered. But what do you do if you need to locate and identify participants indoors? This presentation will provide an introduction to a range of techniques for finding people within a predefined space. It will cover everything from optical tracking and WiFi monitoring to the more recently available iBeacon, and discuss how you can incorporate these techniques into your creative coding projects.
