Non-verbal communication refers to communicating through gestures, body language, tone of voice, and other wordless means. It accounts for over 90% of total communication. Some key aspects of non-verbal communication include facial expressions, eye contact, posture, tone of voice, touch, distance between individuals, clothing choices, and use of time. There are several types of non-verbal communication such as paralanguage, kinesics, proxemics, and haptics. Non-verbal signals can provide additional meaning or context to what is said verbally.
