Blippar's augmented reality app put to the test

Augmented reality app-maker Blippar has found a lucrative use for augmented reality by offering leading brands new ways to connect with consumers.

Point its app at a Coke can, for instance, and it may play you a tune from Spotify.

The software does this by recognising objects and then superimposing information or triggering an action.

The firm's founder Ambarish Mitra gave the BBC's technology correspondent Rory Cellan-Jones a demo.
