Nonverbal communication is the process of communication through sending and receiving wordless (mostly visual) cues between people. It is sometimes mistakenly referred to as body language (kinesics), but nonverbal communication encompasses much more, such as use of voice (paralanguage), touch (Haptic-s), distance (proxemics), and physical environments/appearance. Typically overlooked in nonverbal communication are proxemics, or the informal space around the body and chronemics: the use of time. Not only considered eye contact, oculesics comprises the actions of looking while talking and listening, frequency of glances, patterns of fixation, pupil dilation, and blink rate. Even 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. http://en.wikipedia.org/wiki/Nonverbal_communication
