Directing Attention in Open Scenes
Stephen Hughes, Michael Lewis · Proceedings of the Human Factors and Ergonomics Society Annual Meeting · 2002
Attention direction is particularly difficult in open scenes such as detailed aerial photographs, wide angle/multiple video feeds, or high-resolution digital imagery. Unlike conventional displays that have single parameters with definable set points, open scenes lack easy criteria for directing attention. The present study investigates the effects of varying levels of highlighting for correctly and incorrectly designated targets. The results suggest that linking the intensity of highlighting to degree of confidence may be an effective display strategy to maximize efforts to draw attention to objects in an open scene.
