text: The technology could also help improve the quality of students' learning because it can make sure students are not confused. Often, when teachers ask if everyone understands the material, students who do not understand, will be too emabrassed to ask for help, or the teachers, with such a large class, will not notice if one or only a few students are falling behind. Furthermore, in the article, Dr. Huang states that "'most human communication is nonverbal, including emotional communication" meaning that most communication is picked up in other ways, such as visually. Unfortunately, often in a classroom setting, teachers must face away from their students when writing on a white board at the front of the classroom, or in similar situations, which means that without the visual connection, much of the communication between students and teachers is lost. The new technolgoy could help with this problem, as it could identify students' emotions even when a teacher's back is turned, and thus could alert teachers and help them improve their lessons to fit their students' needs. It could also help evaluate emotions that teachers do not notice, such as if a student is confused, they may try to hide it. This new technology could identify these emotions and help the teacher make sure all of their students understand the material, which would lead to an improved quality of teaching and learning.
