Virtual reality headsets raise some real concerns about people's behaviour

New York

EVERY Friday, a dozen or so people strap on virtual reality headsets, log on to the Internet and do something that would normally require driving to a local multiplex: watch a movie with a bunch of strangers.

Their avatars all sit in the seats of a virtual movie theatre, staring at a screen playing a movie from Netflix. The sound from the theatre is so accurate that if participants munch potato chips into their microphones, it sounds as though it is emanating from their avatars.
