The arrangement of Augmented Reality (AR) labels on mobile displays can cause problems when the labels over populate the screen space. This can result in occlusion, not only of real scene, but also of other labels annotating the scene. We are developing view management systems that arrange and display AR content based on user attention. We present a pilot user study that tests speed and accuracy on a simple information retrieval task on simulated AR scenarios. We varied the presentation in two ways: a naive approach and a gaze-based approach. The results did not show statistical differences between the two methods, yet results from this study provide valuable insight for subsequent studies.
