Abstract

A novel system, called MM+Space, is presented for recreating multiparty face-to-face conversation scenes in the real world. It aims to display and playback pre-recorded conversations as if the people were talking in front of the viewer(s). This system consists of multiple projectors and transparent screens, which display the life-size faces of people. The key idea is the physical augmentation of human head motions, i.e. the screen pose is dynamically controlled to emulate the head motions, for boosting the viewers' perception of nonverbal behaviors and interactions. In particular, MM+Space newly introduces 2-Degree-of-Freedom (DoF) translations, in forward-backward and right-left directions, in addition to 2-DoF head rotations (nodding and shaking), which were proposed in our former MM-Space system. The full 4-DoF kinetic display is expected to enhance the expressibility of head and body motions, and to create more realistic representation of interacting people. Experiments showed that the proposed system with 4-DoF motions outperformed the rotation-only system in the increased perception of people's presence and in expressing their postures. In addition, it was reported that the proposed system allowed the viewers to experience rich emotional expressibility, immersion in conversations, and potential behavioral/emotional contagion.
