A Study of Depth Visualization Techniques for Virtual Annotations in Augmented Reality
K. Uratani, Takashi Machida, Kiyoshi Kiyokawa, Haruo Takemura · 2006
In this paper, we discuss depth visualization techniques for virtual annotations to alleviate the depth ambiguity problem. We begin by describing the depth ambiguity problem with regard to virtual annotations. Then a number of possible solutions are discussed by introducing a metaphor of monocular depth cues, and the effectiveness and characteristics of the three visualization techniques are shown through the preliminary experiments.
