British Airways introduces the Happiness Blanket

British Airways invited seven people on a flight from London to New York and seated them across World Traveller Plus, Club World through to First Class, so they could measure the effect of refinements made in all cabins. A Myndplay headband was used to measure tiny electrical fluctuations in the neurons of the brain. This information was sent via Bluetooth, every second, to fibre optic lights woven directly into each Happiness Blanket. When the blanket goes red, the wearer is stressed and if it goes blue, the wearer is relaxed.

Now that is so much better than filling out a comments card.
