Sign languages are not an artificial system of communication, since each one has its own rules, lexicon, structure and grammar.

While sign language is perceived visually and is expressed through gestures, spoken language is expressed through sounds and is received through an audible signal. For this reason, sign language has some characteristics derived from its communication channel, such as that it is expressed through gestures, hands, head and body movement; uses the space; and can be iconic as well as abstract.
