text: It seems unnecessary to use this technology when emotions are already fairly easy to identify without the use of a computer. Body language and facial expressions can already easily be analyzed by humans themselves to reveal emotions. To quote the writer of the article, "In fact, we humans perform this same impressive "calculation" every day. For instance, you can probably tell how a friend is feeling simply by the look on her face" (D'Alto 5). This depicts that technology is not required to identify the basic emotions of a human being and is therefore unnecessary.
