Emotions are also a tricky thing, as people sometimes try to hide them or fake them. While D'Alto states that "to an expert, faces don't lie," in a educational setting, that often doesn't matter. Most students are often relatively reluctant to learn, possibly putting their face in a perpetual cycle of anger, disgust, sadness, or even fear. In school, education carries on regardless of emotional state. While teachers do care about the emotional wellbeing of their students, they still must teach like the do any other. In general, emotions are often ignored in the face of studying and education - students study what they need to, no questions asked. This raises the question of truly how useful would facial analysis be in an online classroom? There isn't much computers can do to adjust to human emotions. Computers also lack a soul, so they therefore lack emotions and empathy and sympathy. Without those, how could they possibly understand what a student needs? Humans, as D'Alto states, indeed "perform this same impressive "calculation" every day." However, humans can also react much more appropriately. Also, there is no guarantee that the technology would read emotions correctly. And unlike fingerprint scanners or facial recognition, there is no second chance with emotions. Either the computer interprets them incorrectly or correctly. The fact remains that having a facial recognition from an online, unemotional avatar simply would not provide many advantages over a regular online classroom.
