The ability to direct a viewer's attention has important applications in computer graphics,data visualization,image analysis,and training. Existing computer-based gaze manipulation techniques,which direct a viewer's attention about a display,have been shown to be effective for spatial learning,search task completion,and medical training applications. This work extends the concept of gaze manipulation beyond digital imagery to include controlled,real-world environments. This work addresses the main challenges in guiding attention to real-world objects: determining what object the viewer is currently paying attention to,and providing (projecting) a visual cue on a different part of the scene in order to draw the viewer's attention there. The developed system consists of a pair of eye-tracking glasses to determine the viewer's gaze location,and a projector to create the visual cue in the physical environment. The results of a user study show that the system is effective for directing a viewer's gaze in the real-world. The successful implementation has applicability in a wide range of instructional environments,including pilot training and driving simulators.
