Perception of Shared Visual Space: Establishing Common Ground in Real and Virtual Environments
نویسندگان
چکیده
When people have visual access to the same space, judgments of this shared visual space (shared vista) can facilitate communication and collaboration. This study establishes baseline performance on a shared vista task in real environments and draws comparisons with performance in visually immersive virtual environments. Participants indicated which parts of the scene were visible to an assistant or avatar (simulated person used in virtual environments) and which parts were occluded by a nearby building. Errors increased with increasing distance between the participant and the assistant out to 15 m, and error patterns were similar between real and virtual environments. This similarity is especially interesting given recent reports that environmental geometry is perceived differently in virtual environments than in real environments.
