text: Over all The people that you can ask for advice is very large. But always ask multiple people before making any decision,so that you can make the best one. Ask them becasue they have experience, they might get asked that question all the tme,or they know you very well.                                               I think that the "Facial Action Coding System" may actually be valuable. The machine detects emotions from using a picture and that can help with knowing how a person feels. The machine uses the muscles in your face to detect your emotions, it calulates all emotions found, and has most of the common emotions so the FACS has a very good chance of being accurate and valuable.
