Abstract

Virtual reality (VR) has long been used to impart a heightened sense of reality to the user by artificially generating various stimuli. We hypothesize that generating emotions during a VR experience helps to enhance the immersive experience. Therefore, we developed an interactive walk-through system named Emotion Hacking VR (EHVR) that measures user heart rate and provides false vibrotactile feedback to amplify the VR fear experience. To determine the effectiveness of the false vibrotactile feedback, we conducted a comparative experiment to evaluate three calculation methods used to generate the false heart rate. We adapted the most effective method to accelerate the user heart rate in the EHVR system and conducted a hands-on exhibition at the Asia Digital Art Award 2017 exhibition at Fukuoka Asian Art Museum. The objective and subjective results obtained from participants indicate that the increased real heart rate caused by EHVR affected the VR fear experience.
