LightAnchors: Appropriating Point Lights for Spatially-Anchored Augmented Reality Interfaces
Proceedings of the 32nd Annual ACM Symposium on User Interface Software and Technology(2019)
摘要
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 ap-plication 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.
