Directing Attention And Influencing Memory With Visual Saliency Modulation

In augmented reality, it is often necessary to draw the user's attention to particular objects in the real world without distracting her from her task. We explore the effectiveness of directing a user's attention by imperceptibly modifying existing features of a video. We present three user studies of the effects of applying a saliency modulation technique to video; evaluating modulation awareness, attention, and memory. Our results validate the saliency modulation technique as an alternative means to convey information to the user, suggesting attention shifts and influencing recall of selected regions without perceptible changes to visual input.
