text: This system is not valuable in the classroom because computers aren't always right. Computers are not human, you can not program a computer to have empathy or any human emotion. So you can not program a computer to read a humans face and accurately tell them their emotion. Also computer programs tend to have a lot of bugs in them, so this system could have a few hidden bugs that could make the system broken and unusable. Finally, the article states that, "Your home PC can't handle the complex algorithms...", so what kind of computers are students going to use that are capable to run the system?
