text: If a person is not blatantly showing his emotions with body language and facial expressions, then the person wold likely prefer not to express what he is feeling or thinking. All human beings have a natural right to keep their thoughts and emotions to themselves as they please, and technology that can reveal emotions at their deepest depths can be intrusive. An example of this can be how computers use cookies to track what people are searching on the Internet in order to produce advertisements directed toward the user later on, which often disturbs people and makes them feel uncomfortable. This may be the same situation if computers have access to human emotions. The private feelings of a human should not be exploited by a computer, and therefore trespasses a basic right of humans which allows them to have their own private thoughts and emotions.
