Feedback about actions in augmented reality (AR) is limited and can be ambi due to the nature of interacting with virtual objects. AR devices also have a restricted field of view (FOV), limiting the amount of available visual information that can be used to perform an action or provide feedback during or after an action. We used the Microsoft HoloLens 1 to investigate whether perceptual-motor, collision-based outcome feedback calibrates judgments of whether one can pass through an aperture in AR. Additionally, we manipulated the amount of information available within the FOV by having participants view the aperture at two different distances. Feedback calibrated passing-through judgments at both distances but resulted in an overestimation of the just-passable aperture width. Moreover, the far viewing condition had more overestimation of just-passable aperture width than the near viewing condition.
