The future of VR? US researchers may hold the answer

MINNEAPOLIS, Minnesota - At the Mall of US' arenasized Smaaash amusement arcade, people wait in line to slip on headsets that resemble blacked-out ski goggles and spend a couple of minutes feeling transported.

They experience the sensations of flying a jet in combat, rescuing a kitten about to fall from a skyscraper or looping in circles on a roller coaster.

Not far away, the mall's Best Buy carries a range of consumer-level virtual-reality equipment. Salespeople explain how VR works, how it feels and how you might make it a part of your home entertainment collection.
