Preliminary Test of Affective Virtual Reality Scenes with Head Mount Display for Emotion Elicitation Experiment

機関リポジトリ HANDLE

抄録

Emotion elicitation experiments are conducted to collect biological signals from a subject who is in a state　of emotion. The recorded signals are used as training/test dataset for constructing an emotion recognition system by　means of machine learning. In conventional emotion elicitation experiments, affective images or videos were provided　for a subject to draw out an emotion from them. However, the authors have concerns about the effectiveness. To surely　evoke a specific emotion from subjects, we have produced several Virtual Reality (VR) scenes and provided the　subjects with the scenes through a Head Mount Display (HMD) in emotion elicitation experiments. Usability and　effectiveness of the VR scenes with the HMD for emotion elicitation were experimentally verified. It was confirmed　that experience of the VR scenes with the HMD was effective in evoking emotions, but we have to improve how　subjects learn a way of playing VR scenes and provide measures against VR sickness at any cost. Moreover, Support　Vector Machine classifiers as an emotion recognition system were constructed using the biological signals measured　from the subjects in the emotion elicitation experiments.
