Tele-immersion is a new technology that combines virtual reality, 3D videoconferencing, and other media to allow users in different locations to interact and collaborate in a shared virtual environment as if they were in the same physical space. It integrates collaborative virtual reality with audio and videoconferencing to give users the feeling of being together face-to-face. Tele-immersion aims to enhance collaboration and interaction beyond what is possible with traditional videoconferencing alone. It faces challenges related to the need for high-bandwidth networks and advanced computing power to support its real-time, interactive virtual environments.
