This ‘Happiness Blanket’ Measures the Well-Being of British Airways Passengers

To that end, the airline made these not-at-all-awkward brainwave-measuring headbands and connected them to light-up blankets that change color based on how passengers are feeling. Like a mood ring for your whole body.

Stressed is red. Comfy is blue. Because wearable technology is so hot right now, even at 35,000 feet. Also because it's always so much fun to hurtle through space in a tin can that it's only natural to want a device to tell you how good of a time you're actually having, and to broadcast your state of mind to all the other humans crammed in like sardines next to you.

But as nifty as the technology is, and as dazzling as the pretty LEDs are, the whole exercise in self-congratulation would be a whole lot cooler if it told us something more revelatory than the fact that people are at their happiest when they can manage to sleep through the whole ride.

Then again, at least it's more intriguing than just saying outright that the food and seats have improved—especially when the bar for airline food is usually so high.
