A Study on the Effects of Head Mounted Displays Movement and Image Movement on Virtual Reality Sickness

Virtual Reality sickness will make users discomfort. We tested 26 volunteers wearing Oculus Rift. Three different experiments were conducted: (1,2) the effect of VR head-mounted display device (HMD) movement (un)synchronizes with inclination of the image on VR sickness; (3) the effect of image movement direction on VR sickness. The Simulator Sickness Questionnaire was filled by the participants. The results showed that the VR sickness symptoms are relieved when VR HMD doesn’t synchronize with inclination of the image. In addition, the different image movement direction will affect the vertigo feeling. The results will be of help for VR content creation.
