Pictorial Depth Cues for Outdoor Augmented Reality
This paper presents and evaluates a set of pictorial depth cues for far-field outdoor mobile augmented reality (AR). We examine the problem of accurately placing virtual annotations at physical target points from a static point of view. While it is easy to line up annotations with a target point's projection in the view plane, finding the correct distance for the annotation is difficult if the target point is not represented in an environment model. We have found that AR depth cues, such as vertical and horizontal shadow planes, a small top-down map, or color encodings of relative depth, have a positive impact on a user's ability to align a 3D cursor with physical objects at various distances. These cues aid the user's depth perception and estimation by providing information about the 3D cursor's distance and its relationship in 3space to any features that may already have been annotated. We conducted a user study that measures the effects of different depth cues f...
