The Effect of a Bio-signal Interactive Virtual Reality on Subjective Impression - A Preliminary Study

摘要

We developed a bio-signal interactive virtual reality (VR) system to investigate the impression of users as a pilot study. In this study, three different VR scenes were given to the subjects of 20 healthy university students: bonfire (regulated with Electrocardiogram), firefly and butterfly (regulated with respiration signal). The subjective outcomes were assessed using the visual analogue scale. For the purpose of comparison, each subject also experienced the same scenes regulated with sinewave and random signals. The experiment was conducted by within-subject design: each subjects experienced three VR scenes and three input signals (bio-signal, sinewave, and random) in a counter-balanced order. As a result of the experiment, bio-signal interactive VRs can be observed as most comfortable and natural for subjects compared with the sinewave and random conditions.
