- 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
causes:
- nausea (vomiting, dizziness)
- visual symptoms (eyestrains, blurred vision, headaches)
- 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
HUMAN SENSOR SYSTEM
VESTIBULAR SYSTEM
- Balance and control
- Gaze stabilization
VISUAL SYSTEM
- co-ordination
PROPRIOCEPTIVE SYSTEM
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
