• 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:

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

HUMAN SENSOR SYSTEM

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
