Towards Dynamic Perspective Exchange in Physical Games

Video has been used to give people sensations or insights into another person's perspective via providing real time feeds of first person viewpoints. Less explored is rapid and dynamic perspective changing that can introduce uncertainty for users concerning whether their feeds are manipulated, and if they are viewing themselves or another. We report on initial trials of a 3-person wireless headset system. Each headset incorporated an external video camera and an internal screen that provides its wearers with visual information. Camera transmissions are rapidly and automatically switched to be received by different headsets, thus providing wearers with a continuous cycling through 1st, 2nd and 3rd person perspectives. Based upon testing several physical games activities, we offer suggestions to assist developers in designing intense embodied perspective changing experiences.
