ABSTRACT
The research that the author describes so far seems to be consistently showing that the spontaneous gestures that accompany speech can both represent and conveys meaningful information to an addressee, and that addressees process this gestural information and combine it with the information in the speech itself. This research has also clearly demonstrated that many iconic gestures are highly communicative but it also shows that some gestures are significantly more communicative than others. Although Gullberg and Holmqvist's study found that participants' tendency to fixate the gestures was very low, certain types of gestures were found to reliably attract higher levels of fixation. Each participant's point of gaze on the screen was determined by the camera combining the position of the pupil and the corneal reflection. The remote camera in the eye tracker fed into a screen for the experimenter's observation of the positioning of camera observing the eye.
