This study presents a method that displays selectively-blurred images to users wearing a VR Head Mount Display (HMD), for reducing their VR sickness while maintaining rich-presence they feel as much as possible. Our proposed method blurs displayed images selectively based on a specific length and direction of optical flow at each point in the image to not only reduce the VR sickness but also preserve the original rich-presence of the displayed images. The optical flow direction of each point is opposite to that of the whole image, such areas are not blurred in our proposed method. Our proposed method was verified via two types of experiments, the results proved that our method is effective appropriately for both VR sickness reduction and rich-presence preservation.
