text: Technology is advancing more and more each day. In no time, we will improve schools and work areas. The way we communicate will better and the way we read expressions will too. As said in paragraph 8 "to an expert, faces don't lie: these muscle clues are sometimes used to spot when a "smiling" politician or celebrity isnt being truthful"; the same could be applied to students. Facial expressions are important. With these computors or devices put in every class room, students will soon be performing at their top best. Soon enought the decives will be used in work areas, while texting and more.   I disagree with the value of using this technology to read students emotional expression because a picture may be susposed to make you laugh but it only shows what the computer can do.
