Why staring at screens is making us feel sick

We can watch HD films on the train and play games in VR headsets but there's a hitch - motion sickness

When we come to define the overarching feeling of the early part of the 21st century, it may come down to one word: queasiness. Some of the most exciting advances in technology - virtual reality, wearable tech, superfast smartphones and 3D films and operating systems - may all be scuppered by a basic human weakness: motion sickness.

"If you walk into a room, you see the visual input that shows us we're moving, and our vestibular system, the organs of balance, tell us we're moving, [as does] the perception from your muscles and bones," says Dr Cyriel Diels, human factors specialist at the Centre for Mobility and Transport at Coventry University. "Below deck on a ship, you are physically moving, but because you are moving with the boat, the visual field seems to be stationary. The two seem to conflict. Your body responds with motion sickness: vomiting, feeling dizzy."
