Simulator Sickness is a type of Motion Sickness that occurs when using VR and AR devices. The symptoms of simulator sickness are dizziness, headache, nausea, vomiting and other discomforts. Simulator Sickness occurs when the VR devices fails to completely fool our vestibular system, the sensory system responsible for balance and spatial orientation. It is caused by the discrepancies between the motion perceived from the screen of HMD and the actual motion of the user's head and body. In other words simulator sickness from VR is developed when what our eyes see does not match how our heads move. Even minute discrepancy can cause these unpleasant sensations. Simulator sickness is one of the major problems to the wide adoption of Virtual Reality. As hardware and software improve, VR Devices hope to reduce and eventually eliminate simulator sickness.

Gabe Newell from Valve has claimed that its HTC Vive, unveiled in GDC 2015, is the first VR Device that has eliminated simulator sickness from its users. HTC Vive has Lighthouse Motion Tracking system that utilizes lasers to improve the accuracy of the head tracking to under 1/10 of a degree.

What causes simulator sickness

  • Large and frequent acceleration
  • Lack of control from user
  • Using HMDs for prolonged periods without breaks
  • Low altitude or filling FOV with ground
  • Some users find certain stereoscopic images uncomfortable
  • Narrow/low field of view
  • High latency
  • Distortion correction????
  • Flickering or flashing images rapidly
  • Lack of VR experience
