A Visual Feedback Method of Motion Information on Alpine Skiing Experience in Head Mounted Display

One of the sports training methods is VR training, where users watch a video image to recognize the situation, estimate the timing to move, and move their bodies by the situation. In this paper, we propose a real-time visual feedback method for sports motion information on the VR experience of Alpine skiing. We prepare a carefully designed visual feedback panel that presents the user's center of gravity and head height as sports motion information. An HMD presents the skiing situation on the slopes in VR180 style. The load sensor of our preliminary system is placed under the user's feet, and it acquires the center of gravity position. The tracking function of the HMD estimates head height. In the evaluation experiment, we investigated the appropriate parameters to realize the good visibility of the visual feedback panel during VR training.
