4. Introduction
Gestures are a type of non-verbal communication used by a
speaker to aid communication. McNeill (1985) interprets
gestures as the second channel of communication, in
which the first channel of communication is actual speech,
thus implying that gestures add on to speech production.
Alibali et al. (2001) conducted a series of experiments to
see whether speakers would use gestures differently
depending on the need to see gestures when
communicating. The results revealed that speakers would
continue to use gestures when communicating regardless of
the listener’s visibility of their gestures.

communication in which visible bodily
actions communicate particular messages,

human interaction, both interpersonally
and in the context of man-machine
interfaces.
