Predisposition to "motion sickness" in adults or children is multifactorial: genetic, certain medical conditions, recent or concurrent illness. Exposure to real or perceived motion (virtual, large video screens) can precipitate symptoms. Motion sickness may not be obvious at first, particularly in children: yawning, belching, paleness of skin, flushing, sweating, increased salivation, nausea. Children between 3-12 years old have the highest incidence. Children under 2 and elderly have reduced incidence. Motion stimuli that may precipitate illness include acceleration (instant torque), horizontal translational (quick turns), fore- and aft- surge movements (regen, go pedal, regen, go pedal)
