LightAnchors: Appropriating Point Lights for Spatially-Anchored Augmented Reality Interfaces (UIST ’19)
Augmented reality requires precise and instant overlay of digital information onto everyday objects. We present our work on LightAnchors, a new method for displaying spatially-anchored data. We take advantage of pervasive point lights – such as LEDs and light bulbs – for both in-view anchoring and data transmission. These lights are blinked at high speed to encode data. We built a proof-of-concept application that runs on iOS without any hardware or software modifications. We also ran a study to characterize the performance of LightAnchors and built eleven example demos to highlight the potential of our approach.
