Submission + - British Airways Experiments with Electronic Mood Reading Blankets (bloombergview.com)
A British Airways video (embedded in the article) http://www.businessweek.com/ar... describes how its gizmo monitors "neurons in the brain" sensing when a passenger is enjoying a state of well being. Information is transferred via bluetooth to microfibers in the blanket, which turn bright red if the passenger feels anxious. Now, the video explains, British Airways knows — scientifically — that people like to sleep during their flight.
