GAZE‑2 is a novel group video‑conferencing system that uses eye‑controlled camera direction to ensure parallax‑free transmission of eye contact. The study aims to enable eye contact in group video calls using a single video stream per user and to evaluate whether automated camera direction affects perception. GAZE‑2 uses a video tunnel with cameras positioned behind participant images, an eye tracker that automatically selects the camera closest to the user’s gaze, and a virtual meeting room that rotates images toward the looked‑at participant to maintain eye contact. The evaluation shows that camera shifts do not significantly affect eye contact perception and are not highly distracting.
GAZE-2 is a novel group video conferencing system that uses eye-controlled camera direction to ensure parallax-free transmission of eye contact. To convey eye contact, GAZE-2 employs a video tunnel that allows placement of cameras behind participant images on the screen. To avoid parallax, GAZE-2 automatically directs the cameras in this video tunnel using an eye tracker, selecting a single camera closest to where the user is looking for broadcast. Images of users are displayed in a virtual meeting room, and rotated towards the participant each user looks at. This way, eye contact can be conveyed to any number of users with only a single video stream per user. We empirically evaluated whether eye contact perception is affected by automated camera direction, which causes angular shifts in the transmitted images. Findings suggest camera shifts do not affect eye contact perception, and are not considered highly distractive.
