Dancing with physio: a mobile game with physiologically aware virtual humans

Abstract

This study presents an evaluation of a mobile game with physiologically aware virtual humans as an approach to modulate the participant's affective and physiological state. We developed a mobile version of a virtual reality scenario where the participants were able to interact with virtual human characters through their psychophysiological activity. Music was played in the background of the scenario and, depending on the experimental condition, the virtual humans were initially either barely dancing or dancing very euphorically. The task of the participants was to encourage the apathetic virtual humans to dance or to calm down the frenetically dancing characters, through the modulation of their own mood and physiological activity. Results from our study show that by using this mobile game with the physiologically aware and affective virtual humans the participants were able to emotionally arouse themselves in the Activation condition and were able to relax themselves in the Relaxation condition, during the same session with only a brief break between conditions. The self-reported affective data was also corroborated by the physiological data (heart rate, respiration and skin conductance) which significantly differed between the Activation and Relaxation conditions.
