Emotion detector could reveal if a date really finds you attractive: Is this the kind of world we actually want?
Scientists are considering an emotion detector which, potentially, can tell whether a person really finds you attractive on a first date. Ref. Source 2p.
While this will be cool how will you be able to work it without the other person knowing you have it? I think body language can give you clues more than any 'detector' can because some people are just really good actors!
Why rely so much from technology? In the end we will forget how to be humans. The internet has already alienate us from our immediate environment… but I guess there will be people who will buy such devices. Sad…
While it may seem "Sad" there are people who cannot tell if someone is attracted to them or not and this device may be a help for them specially if its developed for other applications like telling when someone is angry at you..
