text: Technology is taking over the world and i understand that, but i feel as technology should not get involved with the human features. Reading students emotional expressions in the classroom is not valuable. This system could give teachers the wrong impressions on how their students are thinking or feeling. For example a student in your class could be very sickand look sad because their not feeling good. You as the teacher might think that he/she is sad because of some other reason such as a personal reason.
