Rate the following essay on its writing, argument, and language skills:
There are many differences in telling which is a geniune smile and which is a false smile, and technology can help with differentiating the true meaning of smiles. The professors in the article help show how computers can understand what people like and dislike. The professors in the article explain how computers can identify facial expressions and the result could be a long term effect. According to Professor Huang and Professor Sebe, a computer would be able to identify if someone is faking a smile or is geniunely happy in their life. A computer that can recognize facial expressions can greatly help people by showing if they are unhappy or depressed, and show advertisements that people are interested in.

Faking a smile can mean multiple emotions are present. If someone is faking a smile, then that person could be depressed. In paragraph eight, "in a false smile, the mouth is stretched sideways ... using a different muscle." Computers and facial experts can tell if someone is unhappy by examining the subject's face and deciding whether they used their zygomatic major and the risorius muscle to smile. The subject's life is affected by an expert or computer telling the person that they are unhappy, which can lead to the person getting help. Achieving better health could all be from the idea that a computer is able to tell if someone is unhappy and a result of that is the person seeking help. In paragraph nine, "moving [one's] facial muscles not only exresses emotions, but may also even help produce them." Computers can recognize if someone is making a facial expression and that works by making emotions for the person to feel any type of feeling. Because of computers recognizing what a person is feeling, computers should be able to communicate with a person and express to that person what they are feeling or experiencing.

Advertisements also help show emotions. In paragraph six, smiling when a Web ad appears, might make "a similar ad ... follow." Computers can tell if someone is enjoying the advertisements and might add another similar ad that could be enjoyable for that person again. Advertisements can add to the health of a person by allowing that person to experience happiness and adding another ad to the web is just increasing their health. However it is different for a person in a workplace or classroom, according to paragraph six, such as a classroom computer can "recognize when a student is becoming confused or bored." Boring ads can decrease a persons health by making that person have less motivation to do their job or work. Advertisements have an effect on people's health in which so adds to why computers should be able to communicate with people about their feelings.

Computers should be able to communicate with people about their feelings, because it can help people greatly in the aftermath. Computers can help by discovering if the person is unhappy in life or can increase their health by allowing that person to experience a happy moment. A person who discovers that they are depressed from a computer that tells them, can expect so much. A person can expect to achieve happiness by seeking help. Computers also increase a persons happiness level from the advertisements that pop up on a computer. What goes to show is that computers should be able to continue communicating with people about their feelings for it helps people recognize the greater meaning in life such as happiness.
