PatternTrack: Multi-Device Tracking Using Infrared, Structured-Light Projections from Built-in LiDAR (CHI ’25)

As augmented reality devices (e.g., smartphones and headsets) proliferate in the market, multi-user AR scenarios are set to become more common. Co-located users will want to share coherent and synchronized AR experiences, but this is surprisingly cumbersome with current methods. In response, we developed PatternTrack, a novel tracking approach that repurposes the structured infrared light patterns…
