LightAnchors array: LEDs in routers, power strips, and more, can sneakily ship data to this smartphone app

Talk about gone in a flash


Video A pentad of bit boffins have devised a way to integrate electronic objects into augmented reality applications using their existing visible light sources, like power lights and signal strength indicators, to transmit data.


In a recent research paper, "LightAnchors: Appropriating Point Lights for Spatially-Anchored Augmented Reality Interfaces," Carnegie Mellon computer scientists Karan Ahuja, Sujeath Pareddy, Robert Xiao, Mayank Goel, and Chris Harrison describe a technique for fetching data from device LEDs and then using those lights as anchor points for overlaid augmented reality graphics.


As depicted in a video published earlier this week on YouTube, LightAnchors allow an augmented reality scene, displayed on a mobile phone, to incorporate data derived ..
