We aim at examining how communication mode
influences the production of gestures under specific
contextual environments. Twenty-four participants were
asked to present a topic of their choice under three
instructional settings: a blackboard, paper-and-pencil, and a
tablet. Participants’ gestures were investigated in three
groups: deictic gestures that point to entities,
representational gestures that present picturable aspects of
semantic content, and beat gestures that are speech-related
rhythmic hand movements. The results indicated that
gesture production of the participants was influenced by the
mode of instruction (i.e., board, paper-and-pencil, tablet).
