What happens if you go to the cinema wearing Google Glass?

Technology correspondent Rory Cellan-Jones finds out what happens if you wear Google Glass to watch a film in the UK.

His trip to the cinema follows a call by head of the Cinema Exhibitors' Association (CEA) Phil Clapp that smart glasses should be banned in UK cinemas.

The CEA has no power to enforce a ban, but instead makes recommendations to most of the country's cinema industry.
