Adam Jones will be giving the first talk in the INST 2006 Colloquium Series entitled "Egocentric Depth Judgments in Optical, See-Through Augmented Reality":

Augmented reality (AR) is a method of mixing computer generated graphics with real-world environments. In AR, observers retain the ability to see their physical surroundings while additional (augmented) information is depicted with simulated graphical objects matched to the real-world view. AR has numerous potential applications including medical imaging, navigation, military strategy, and entertainment.

When viewing objects in an AR environment, observers are presented with conflicting depth cues. Many of these inconsistencies are due to the engineering limitations present in the design of head mounted displays. Before practical AR systems can be implemented, we must understand what limitations are present and if there are ways we can compensate for these shortcomings. A key factor in this process is determining how observers perceive egocentric depth relations in augmented environments. Our goal is to utilize methods of perceptual measurement to determine how observers map the positions of real-world and virtual objects.

In our study, subjects are presented with varied real, virtual, and combined stimuli. The apparent locations of the stimuli are then measured using quantitative methods of egocentric depth judgment. The data collected from this experiment provides information as to how subjects perceive egocentric depth with respect to both real-world and virtual objects, as well as further insight into how more functional, ubiquitous augmented environments can be engineered.

Adam's talk will be Thursday, October 26th, at 3pm in the INST classroom.
