| Abstract | The ability to direct a viewer’s gaze about a scene has important ap-plications in computer graphics and data visualization. The Subtle Gaze Direction (SGD) technique developed by Bailey et al. [2009] provides the ability to guide a viewer’s gaze to specific regions of a display. The technique, which combines real-time eye-tracking with subtle image-space modulation, has minimal impact on view-ing experience as it does not change the overall appearance of the scene being viewed. Subtlety is achieved by presenting the modu-lations only to the low-acuity peripheral regions of the field of view so the viewer is never allowed to scrutinize the modulations. The technique has been shown to be quite fast and accurate: viewers typically attend to target regions within 0.5 seconds of the onset of the modulation and the resulting fixations are typically within a single perceptual span of the target. While this shows that the tech-nique is successful at directing gaze, it does not necessarily mean that the viewer fully processed the visual details of those regions or remembered them. To gain a better understanding of the level of visual processing involved, we conducted a study to determine the impact of SGD on short-term spatial information recall. |
