They do not include these movements as gestures with the premise that they are
neither significant nor observed. In this assumption the role of the ‘observer’ is of
great importance, it depends on him to evaluate the received information and decode
it into meaningful movements, hence, based on the same definition, becoming
gestures. Furthermore, the production of identifiable characters or of words is not
absolutely separable from the graphical function in the case of handwriting or from
the articulation/sequence of event characteristics, but these are essential to their
realization. (Cadoz, Wanderley 2000).
