text: The facial expression machine would be fun to have until we need something more new that can read facial expressions and nonfacial expressions. The reason we need something more new i becuase the fact that the machine can get it wrong if the person isn't showing a facial expression. Like you can't just tell by that becuase they can go wrong. The person may not show emotions that much so they can hide it really well. Also people don't really like to tell people how they are feeling.
