text: The technology is able to identfy a human's true emotions, but that will not alter the way that person feels. Humans can often acknowledge how they are feeling, but the acknowledgement itself does not allow them to feel better. As stated in the article, "They even indicate the difference between a genuine smile and a forced one" (D'Alto 7). This line states that the lab partner will be able to tell a difference netween a genuine and meaningful smile from a harshly forced smile. There is a difference between the two because smiling will not make you happy although it is a happy gesture. The machine informing someone that they need to smile will not actually change the emotions of that person. Politicians and celebrities are major culprits of this action. They often smile as they are told to do, but they are not always genuine. They are typically hiding something from their spectators such as when they are not being truthful (D'Alto 8). Just because famous people smile when talking or looking at their audience does not change whether or not they are happy individuals. If humans themselves are unable to change their emotions when they can detect that something is wrong, then machines will be unable to do that also. Although it can give people a precise measurement of their emotions, it will not change how they feel. Therefore, investing in this system would be extremely useless and wasteful.
