  • staircases
  • backwards or quick lateral movement
  • minimal shifts to the horizon line
  • head bobbing


Over 80% of individuals exposed to VR simulations of 20 minutes reported increases in sickness symptoms

GENERAL

reverse to motionsickness (Seekrankheit) not an illness: the ones, who don't have it suffer by a disfunction

  1. nausea (vomiting, dizziness)
  2. visual symptoms (eyestrains, blurred vision, headaches)
  3. disorientation (vertigo, imbalance)

long list, very subjectiv: general discomfort, difficulties in the ability to focus, increased salivation, excessive sweating, feelings of heaviness in the head region, stomach awareness, panic

virtual helmet: closeness of the screen, stereoscopic

THEORY

1. SENSORY CONFLICT

2. INTOXICATION

IMPACTS

Individual's characteristics

  • Physical characteristics (age, gender, ethnic, health)
  • Prior experience
  • Concentration

System's characteristics

  • Helmet comfort
  • Framerate
  • Beginning and ending

Simulation's characteristics

  • Visual stress (sudden stopps, brightness, resolution and contrasts, observed regions)
  • Virtual display (metaphors, frames, horizont, own body)
  • Periods


military quote: 'suggestions for pilots in simulators'

  • don't suggest to users they will get sick or let them see someone else getting sick (it's contagious)
  • don't get into a VE if you are hung over or have an upset stomach
  • Adaptation is a good fix - do VE every day
  • don't do the real thing the same day you do it in a VE
  • get set before turning the VE on
  • try low light intensity, e.g. night flying
  • don't roll or pitch too much
  • don't move your head too much
  • turn off the VE before getting out
