text: Another reason facial recognition can be useful, is in relationships and partnerships . Many people say that they can't tell how their friend or partner is feeling, but with this new software you just might be able too. In the passage it states that "you can probably tell how a friend is feeling by the look on his/her face. Of course, most of us would have toruble actually describing each facial trait that conveys happy, worried, etc." We might have had trouble detecting those emotions in the past, but not anymore. With this software you can always tell if your friend or partner is angry, sad, worried, or in trouble.
