text: But in some other cases, it should not be used in schools or in working areas, dont you think that the students will kind of be scared of that? theres no use for it, maybe some people will make use out of it but some people dont want you "reading" their emotions at all, and you have to respect that. Have you ever wondered exactly what other people were thinking or feeling? Do you know students who are often confused when they learn? Have you ever considered what it would be like if you could tell what other people were feeling exactly? A new technology called Facial Action Coding System has been tested to find the exact emotions of other people. For example, in the first sentence of the first paragraph it describes Mona Lisa's exact emotions in percentages. Many people wonder if this new technology could be useful in a classroom to detect whether children reallly understand a concept or if they just say they understand.
