Nonverbal communication (NVC) is usually understood as the process of communication through sending and receiving wordless messages.

NVC can be communicated through gesture and touch (Haptic communication), by body language or posture, by facial expression and eye contact. NVC can be communicated through object communication such as clothing, hairstyles or even architecture, symbols and infographics. Speech contains nonverbal elements known as paralanguage, including voice quality, emotion and speaking style, as well as prosodic features such as rhythm, intonation and stress. Dance is also regarded as a nonverbal communication. Likewise, written texts have nonverbal elements such as handwriting style, spatial arrangement of words, or the use of emoticons.

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, the physical characteristics of the communicators, and behaviors of communicators during interaction.
