British Airways has been testing the “happiness blanket”, a high-tech blanket that changes colors according to the passenger's emotions. The blanket has optical fibers woven into it that can sense the brainwaves of the user with the use of neuro-sensors measuring a person’s brainwaves. It then changes color, from red to blue, to show when they are at their most relaxed and meditative to anxious. The blanket connects with a headset via Bluetooth that tracks the brainwaves. The tiny LEDs glow according to the feed it receives from the headset.
Why? “Using technology like the ‘happiness blanket’ is another way for us to investigate how our customers’ relaxation and sleep is affected by everything on board, from the amount of light in the cabin, when they eat and their position in the seat,” British Airways said in a news release.
