The theory that language evolved from manual gestures, termed Gestural Theory, dates back to the work of 18th-century philosopher and priest Abbé de Condillac, and has been revived by contemporary anthropologist Gordon W. Hewes, in 1973, as part of a discussion on the origin of language.
The concept implies that the gesture, "the actual motion of the gesture itself", is a dimension of meaning. This enhancement is possible if the gesture "is" the very image; not an "expression" or "representation" of it, but "it". From this viewpoint, a gesture is an image in its most developed: that is, its most materially, naturally embodied form.
Gestures are distinct from manual signs in that they do not belong to a complete language system. [6] For example, pointing through the extension of a body part, especially the index finger to indicate interest in an object is a widely used gesture that is understood by many cultures [7] On the other hand, manual signs are conventionalized—they are gestures that have become a lexical element ...
Gestures are culture-specific and may convey very different meanings in different social or cultural settings. [2] Hand gestures used in the context of musical conducting are Chironomy, [3] while when used in the context of public speaking are Chironomia. Although some gestures, such as the ubiquitous act of pointing, differ little from one ...
Use of the broadest definition of gesture (not restricted to hand movements) allows Hockett’s “rapid fading” design feature of human language to be accommodated as a type of sign in semiotic theory. But if an articulatory gesture is to be considered a true gesture in the above sense, it must be meaningful.
Gesture recognition is an area of research and ... but some companies are challenging this theory. Software-based gesture recognition technology using a standard 2D ...
In scuba diving, the thumbs-up gesture is a specific diving signal given underwater, in which the diver indicates that he or she is about to stop his or her dive and ascend. This occasionally confuses new divers, who might automatically gesture thumbs-up when trying to indicate approval—actually indicating a desire to stop diving and to ascend.
Symbolic communication includes gestures, body language and facial expressions, as well as vocal moans that can indicate what an individual wants without having to speak. Research argues that about 55% of all communication stems from nonverbal language. [2] Symbolic communication ranges from sign language to braille to tactile communication skills.
