text: Teaches do not need technology to tell if their students are bored, as the text says, people just know what the emotions of others are. The teacher would know when, and how to modify the lesson to keep their students interested, and engaged. Would we know what the technology would do to modify the lesson? Would the students just be able to be angry at the lessons until the computer just stops giving the student lessons? Using this tech is not an alternative to having a real person tell how you feel. The teacher can help you feel better because they know how you really feel, because they have empathy. The computer can tell how you feel, but it does not what it is like to feel, so in the end it can't really help.
