When a user participates in a video conference while using a multi-monitor setup, the user’s video feed often shows the user looking away from the camera when the user views a monitor that is in a different direction than the camera, even when such a monitor includes another camera. This disclosure utilizes computer vision techniques, such as face detection and head pose estimation, to automatically switch between multiple available cameras based on detecting the one that the user is looking toward. Such automatic switching ensures that the user’s video feed in the video conference shows the user looking towards the camera, thus enabling better eye contact.
