Surface effects on alignment of graphic and real objects in a stereoscopic augmented reality environment

This poster provides the latest experimental result of a virtual pointer (VP) alignment task at designated probe positions on a cylinder real object surface in a stereoscopic augmented reality environment. The purpose was to evaluate subject's sensitivity to surface texture, target position on the curved surface, VP form, and binocular disparity. The main findings were: a) surface texture had a significant effect, highly textured surface facilitated higher localization accuracy than low textured surface; b) target position had a significant influence, with the central position relative to the observer had less error than the off-centre position; c) binocular disparity had a perceptual interaction with the target position.
