Facial expression is an important tool for face-to-face communication. The different expressions you make with your face can explain your words in more detail. The people that you are communicating with receive many clues from your facial expression that your words may not give. These clues can be a sneering smirk or slight smile that tell your true feelings about what you are communicating.
It is very important that the people whom we are communicating with understand the meaning of the message we are trying to get across. Words help you give meaning to a message that you have in your head. Words can be the most effective type of face-to-face communication because most of the time you can say exactly what you are thinking in your head and get the exact message across without confusion.
Gestures are a form of face-to-face communication that uses physical movements to convey messages. Smiling is a good example of how a gesture can convey a message without using any words or any other body language. A simple smile can convey a positive message that anyone can understand. Gestures allow you to use your hands for nonverbal communication in a face-to-face situation.
Body language is using your body movements and motions to convey a message. Body language is an important face-to-face communication tool because you can communicate almost anything by using your entire body to express different emotions. For instance, looking down at your watch during a face-to-face conversation conveys the message that you are uninterested and may be considered rude. Almost any motions you make while conversing can be taken as body language and conveys a message.
