Eye contact is when two people look at each other's eyes at the same time; it is the nonverbal way of indicating engagement, interest, attention and involvement.
Body language is a kind of non verbal communication, where thoughts, intentions, or feelings are expressed by physical behaviors, such as facial expressions, body posture, gestures, eye movement, touch and the use of space.
A gesture is a movement of part of the body, especially a hand or the head, to express an idea or meaning.
Facial expressions are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species.
