Effects of head-mounted and scene-oriented video systems on remote collaboration on physical tasks

This study assessed the value of two video configurations—a head-mounted camera with eye tracking capability and a scene camera providing a view of the work environment—on remote collaboration on physical (3D) tasks. Pairs of participants performed five robot construction tasks in five media conditions: side-by-side, audio-only, head-mounted camera, scene camera, and scene plus head cameras. Task completion times were shortest in the side-by-side condition, and shorter with the scene camera than in the audio-only condition. Participants rated their work quality highest when side-by-side, intermediate with the scene camera, and worst in the audio-only and head-camera conditions. Similarly, helpers’ self-rated ability to assist workers and pairs’ communication efficiency were highest in the side-by-side condition, but significantly higher with the scene camera than in the audio-only condition. The results demonstrate the value of a shared view of the work environment for remote ...
