Abstract

ITU-T G.1070 [7] is widely cited for evaluating the subjective quality of the video conferencing, but its findings cannot be applied to the tele-immersion. The reasons are two fold. First, a tele-immersive system offers end users an unmatched realistic and immersive experience by allowing them to collaborate in the joint virtual space. Second, the human activities in the shared space are not limited to the conferencing conversation. In this paper, we conduct a user study with 19 participants to investigate the human perceptions of two tele-immersive shared activities, where media samples of different qualities are evaluated using the comparative category rating method [9] in case of each activity. We compare our subjective results to those presented in G.1070, and demonstrate heterogeneous human perceptual impacts in different activities.
