Does Motion Parallax Improve Communication Efficiency in Video Chats?
As video communication has become more prevalent in our day-to-day lives, it becomes evident that face-to-face communication vastly outclasses video chat in terms of peer communication. Motion parallax is a perceptual effect that arises when an observer moves relative to their surroundings, or …
