HaloTouch: Using IR Multi-Path Interference to Support Touch Interactions with General Surfaces

Published in Proceedings of the 2025 CHI Conference on Human Factors in Computing Systems (CHI '25), 2025

We developed HaloTouch, a vision-based system which exploits a multipath interference effect from an off-the-shelf time-of-flight depth camera to enable fast, accurate touch interactions on general surfaces.
