HMDを用いた360度動画視聴時の座面の回転がユーザ体験に及ぼす影響

抄録

The authors examined the effects of chair swiveling with the psycho-physiological effects of viewing short segments of 360° videos using a head-mounted display (HMD) in terms of the type of content. Twenty participants viewed 360° videos with varying features using an eye-tracking HMD consisting of a smartphone fitted in a case containing optics. Ten participants were seated on a swivel chair and the others on a fixed one. Objective indexes on gaze and body rotation and subjective indexes on simulator sickness, emotional reaction and immersion were measured. It was found that the features of content, especially camera motion, affect psychological effects like discomfort and observation behavior, and chair swiveling affects the behavior looking around, the reception of visual information and emotional response. It turns out that the rotating chair, which is easy to think that it supports the action the user sees, does not necessarily contribute to the user experience.
