text: People want to know how to make the best decision and the way that they do that is by asking for advice. When someone is unsure about whether or not their choice is the right one and they ask another person, that person is boosting their confidence. The reason that people ask more than one person for advice, is so that they can be confident in their choice, have a variety of opinions, and know what other people have experienced. There are many ways for a human being to convey an emotion with a facial expression. Someone can indicate happiness by smiling, sadness by frowning, or, confusion by furrowing their eyebrows. Each facial expression signifies someone's emotions or thoughts to others. The Facial Action Coding System (FACS) is a new technology that allows computers to recognize and identify human emotions. Although the FACS is a creative and unique way of identifying human emotions, using the FACS to read emotional expressions of students in a classroom is not valuable.
