A Virtual Reality Sickness Reduction based on Real-time Individual Characteristics

Abstract

The virtual reality (VR) sickness occurring while watching the VR head-mounted display (HMD) video is one of the reasons that does not have a positive effect on the distribution and spread of the VR content. To solve this, various methods are being studied for reducing VR sickness in the content, whereas the effects are insufficient. In addition, studies have also not been conducted to reduce VR sickness based on real-time individual characteristics while watching the VR HMD video. Therefore, this study proposed a VR sickness reduction method based on real-time individual characteristics. The proposed method was verified by comparing the effect of various methods for VR sickness reduction using two experiments. In the first experiment (Experiment Ⅰ), a dynamic visual guide (VG) effectively reduced VR sickness among various methods (static VG, dynamic VG, sound, and field of view (FOV)). In the second experiment (Experiment Ⅱ), the effects of VR sickness reduction of the five dynamic VGs were compared to derive the most effective dynamic VG properties. From these results, VR sickness significantly reduced when the properties of the dynamic VG was 30% of the size of the aspect ratio and positioned to move clockwise (CW) every second, or size changed every second between 30% and 50% of the size of the aspect ratio and positioned in the viewpoint direction.
