Depth cueing for augmented reality

Computer-augmented reality systems promise to overcome some of the problems inherent in virtual reality and, in addition, to provide numerous other application possibilities. However, if augmented reality is to become fully practicable a number of hurdles need to be surmounted. Not least of these is the ability to achieve convincing real-time visual integration of virtual objects within real scenes. To this end, it is particularly important that virtual entities appear to exist at their appropriate depth within a real environment. This article outlines an experimental system to determine the efficacy of alternative static monocular depth cues in an augmented reality display
