Depth judgments by reaching and matching in near-field augmented reality

In this abstract we describe an experiment that measured depth judgments in optical see-through augmented reality (AR) at near-field reaching distances of ~ 24 to ~ 56 cm. The 2×2 experiment crossed two depth judgment tasks, perceptual matching and blind reaching, with two different environments, a real-world environment and an augmented reality environment. We designed a task that used a direct reaching gesture at constant percentages of each participant´s maximum reach; our task was inspired by previous work by Tresilian and Mon-Williams [6] that found very accurate blind reaching results in a real-world environment.
