text: I agree on using this type of technology because you could tell how people and students are feeling. This is also helpful because it would be easier for teacher to help you out when your confused and having trouble with things when some students are to shy to ask for help. These classifieds 6 basic emotions of people like disgusted, happy, sad, fearful, angry, and surprise. Computers can even know if your happy or sad, some people don't really talk and mostly spend time on their computer so also for the computer to know if their happy or sad is helpful.
