Facial expression recognition. I was talking with one big data analysis vendor who claimed they installed expression recognition software outside toilet stalls in the Dubai airport. If you exited the khazi with a disgusted expression, the system would recognize it and dispatch a cleanup crew.

They also claimed they could detect if students were bored in class and feed this info back to the teacher. Up next: thoughtcrime.

I wouldn’t have lumped expression recognition with what one is thinking.

It’s feasible that a person could leave a toilet with a displeased expression while pondering some peculiar nuance of some specific domain of knowledge.

But maybe in this context you’re right, the article meant to refer to expression recognition.

Amazing anecdotes.

> even what she thinks

I don't think the cameras can track your mind. I think it is a little bit of exaggeration, and refers to e.g. knowing one's political leanings by analyzing online accounts.

It's given away by your eye saccades.
