Abstract
A virtual pointer (VP) alignment task at designated probe points on a cylinder real object surface was carried out in a stereoscopic augmented reality environment. The object was to evaluate subjects' sensitivity to surface texture, target position on the curved surface, VP orientation relative to the surface, and binocular disparity. The main findings were: a) surface texture had a significant effect, with highly textured surfaces facilitating less error than low textured surfaces; b) target position had a significant influence, with the central position relative to the observer being better for locating surface positions than the off-centre position. Results are discussed in terms of hypothesised visual perceptual interactions.
