I'm curious about the tests to measure our emotions.
What kind of test is it that can measure an emotional change before and after reading a story, which I guess takes 20min to read. Do they ask the same questions?. Anyone know more about this?

I've often thought that an interesting use of facial recognition would be a component of phone UI. So if I get a call and the phone sees my face looks angry when I see the caller ID, it autoroutes to voicemail.
