This work was funded by the Stanford Regional Visual Analytics Center, through the U.S. Department of Energy's Pacific Northwest National Laboratory. Portions of this research were supported by NSF grants HHC 0905417, IIS-0725223, IIS-0855995, and REC 0440103. Our eye tracker was funded by the Stanford MediaX project and the Stanford School of Engineering. Some of the data from the aural presentation condition of all three experiments were presented at the Eye Tracking Research and Applications conference (Klingner, Kumar, & Hanrahan, 2008). The experiments described in this article were conducted in compliance with the policies of Stanford's institutional review board. All participants gave informed consent, and their rights and safety were protected.
