British Airways tests a ‘Happiness Blanket’ to help judge the mood of the airline’s passengers

British Airways is testing a new blanket, which was used recently as a test on a flight from London to New York City, that measures how you’re feeling on the flight via the colour of the blanket. It reacts to the levels of enjoyment whist eating or watching a movie. A brainwave measuring headband is linked to fibre optics in the blanket.
