Nonverbal communication is the process of communication through sending and receiving wordless (mostly visual) cues between people.
Messages can be communicated through gestures and touch, body language or posture, physical distance, facial expression and eye contact, which are all types of nonverbal communication. Speech contains nonverbal elements known as paralanguage, including voice quality, rate, pitch, volume, and speaking style, as well as prosodic features such as rhythm, intonation, and stress.
Likewise, written texts have nonverbal elements such as handwriting style, spatial arrangement of words, or the physical layout of a page. However, much of the study of nonverbal communication has focused on face-to-face interaction, where it can be classified into three principal areas: environmental conditions where communication takes place, physical characteristics of the communicators, and behaviors of communicators during interaction.
