In 2021, Google unveiled Project Starline, a physical booth designed to make video conversations feel like you’re in the same room with the other participant. Unlike a traditional monitor or videoconferencing station, Starline’s booths are powered by a dozen depth sensors and cameras (together producing seven video streams from four viewpoints and three depth maps), as well as a fabric-based, multilayered light-field display, and four spatial audio speakers. These features allow participants to be captured and then rendered using volumetric data, rather than flattened 2D video.
