text: Technology is big nowadays, which mean more and more new inventions would come into the future. Yes, this invention can work pretty good but it can also cause problems. Just by looking at the muscles of the human face on a computer doesn't mean you can tell that one person is angry or happy, there's so many emotions in one person and you can guess angry but instead they're sad. I think that students in class that has this technology should look at people's faces and tell if they're sad or happy. The Mona Lisa is an amazing example, it's hard to tell if she's either mad or happy, and instead of using technology to figure that out, look at her face and see if she's either angry or happy.
