Here is another one that might invite the "cool or creepy" question. It is British Airways' happiness blanket. It features fiber optic sensors that can "read" your emotional state. If you are tense, it turns red. If you are content, it is blue.
The goal is to help flight attendants monitor passengers' emotions and adjust the in-flight experience in real time -- including, for example, the level of cabin lighting and the timing of meal service.
Will this technology help next winter when you are stuck on the tarmac at LaGaurdia for 2 hours and boiling mad? Probably not. Right now, it is just an experiment. But it seems like an interesting step toward improving air travel, which too often is a downright dreadful experience.
