AUDITORY DISPLAYS ON THE DEPTH OF HYPERTEXT

This study presents an overview of work on the effects of auditory displays on the navigation of hypertext and the results of 2 new experiments. In the present study, auditory information was pertinently mapped with the depth dimension of structural hierarchy in the hypertext. The general finding of the experiments is that auditory displays have the possibility of the redundant effect facilitating the performance on target search tasks, especially difficult target search situations in website navigation. These findings will be discussed and related to the theoretical framework of multimodality effect in the information processing theories.
