text: By using this technology in classrooms, it is useless. It can not read in deatail of how the students are actually feelings, it cannot tell in dept of emotions. In paragraph three it states "Eckman has calssified six basic emotions- happiness, surprise, anger, disgust, fear, and saddness, and then associated each with characteristic movements of the facial muscles". Here one can see that these computers only reads basic emotions. These basic emotions can be read by humans. We have our fellow humans to be able to tell how we feel, more than a computer.
