PERSONAL SPACE-BASED MODELING OF RELATIONSHIPS BETWEEN PEOPLE FOR NEW HUMAN-COMPUTER INTERACTION
Toshitaka Amaoka, Hamid Laga, Suguru Saito, Masayuki Nakajima · 2009
In this paper we focus on the Personal Space (PS) as a non-verbal communication concept to build a new Human Com-puter Interaction. The analysis of people positions with re-spect to their PS gives an idea on the nature of their relation-ship. We propose to analyze and model the PS using Com-puter Vision (CV), and visualize it using Computer Graph-ics. For this purpose, we define the PS based on four pa-rameters: distance between people, their face orientations, age, and gender. We automatically estimate the first two pa-rameters from image sequences using CV technology, while the two other parameters are set manually. Finally, we cal-culate the two-dimensional relationship of multiple persons and visualize it as 3D contours in real-time. Our method can sense and visualize invisible and unconscious PS dis-tributions and convey the spatial relationship of users by an intuitive visual representation. The results of this paper can be used to Human Computer Interaction in public spaces.
