text: You could argue that the use of the technoloy is valuable cause maybe they used that to make Mona Lisa Smile thats the name the article. So they could've used that as a advantage.I beleieve that the use of this technology in classrooms is valuable. This new technology can read emotional expressions of students in a class setting. The technology could help teachers know if the students understand or not. This could also improve grades. Even police officers could use this instead of liar detecters. I say this could be a good tool.
