Evaluation study on realistic sensation in tele-communication environment with ultra-resolution video by multiple cameras on tiled display wall

Abstract

To enhance a high-realistic sensation for participants in tele-communication over the Internet, space sharing by displaying super-quality video is effective. However, in commonly used tele-communication systems, participants have found it difficult to feel an ordinary presence and realistic sensation in real environments, and an effective solution has still not been proposed. We have constructed a tele-communication environment to display an ultra-resolution video which realizes a display resolution over 4K on a tiled display wall by multi-transmitting each video captured by multiple cameras. Nonetheless, the need for objective evaluation and analysis on the realistic sensation that participants feel in tele-communication has been increasing. However, there are only a few case studies on detailed analysis and evaluation of the factors required for realistic sensation in tele-communication. In this paper, we have conducted an experiment to evaluate and analyze the effectiveness of realistic sensation and its effect on participants in this tele-communication environment. From experimental results, we have shown that this tele-communication environment has a strong tendency to provide higher realistic sensation for estimators.
