Tasks assessing the ability to judge distance (A1–C1) and to perceive 3D (D1) in AR. For the distance judgment tasks, either objects of Activities of Daily Living (ADL) were used (A2–C2) or geometric spheres were presented (A3–C3). A1–D1 show two-dimensional illustrations of the tasks, A2–C2 and A3–C3 show screenshots from the visual field of the user while wearing the Microsoft HoloLens®. CAVE: Screenshots deviate from the real projection of objects via the Microsoft HoloLens®. The impression of depth as displayed with the Microsoft HoloLens® cannot be displayed on a two-dimensional screen
