Comm105-Facial expressions

The human face has so many muscles in it to help show what kind of emotion we are feeling.  You ever wonder what our face looks like the moment we feel confused, angry, sad, or amused.  I think it won't be the same if you try to recreate it in a mirror.  The same goes for eye movements.  Whenever someone feels like they are uncomfortable or trying to hide something, they almost never look you in the eye in a face to face interaction.  Some people might call it a tell, if they thought the person was lying about something.  Eye movement can also tell you if someone is intoxicated or under the influence of a a substance.  Eye movement can be very rapid or look like they are very heavy to a person.  Vertical nystagmus is a way of seeing if a persons eyes start shifting very rapidlly when they are told to look directly to the side without any signs of rapid shakiness to their eyes.

There are so many ways to show emotion in the face and eyes that without this capability, we could not communicate effectively to other people, exactly how we feel.
