British Airways conducted an experiment on passengers at 30,000 feet using neuro-sensitive device that reads the electrical activity in their brain.
The airline company was able to identify whether the customer was comfortable and content or feeling slightly more unnerved.
The information was then relayed via bluetooth to the fibre optics woven into the blanket’s fabric, causing it to glow a certain colour accordingly. The blankets turned red if the passengers were feeling stressed and blue if they were more comfortable. Watch the video below.
