N2 - We rely on our sight when manipulating objects. When objects are occluded, manipulation becomes difficult. Such occluded objects can be shown via augmented reality to re-enable visual guidance. However, it is unclear how to do so to best support object manipulation. We compare four views of occluded objects and their effect on performance and satisfaction across a set of everyday manipulation tasks of varying complexity.The best performing views were a see-through view and a displaced 3D view. The former enabled participants to ob-serve the manipulated object through the occluder, while the latter showed the 3D view of the manipulated object offset from the object’s real location. The worst performing view showed remote imagery from a simulated hand-mounted cam-era. Our results suggest that alignment of virtual objects with their real-world location is less important than an appropriate point-of-view and view stability.
