Figure 3.

Mixed reality photo of our HoloLens 2 applications for all three settings which are presented to the participants. The fixation grid for settings I and II is displayed at a fixed distance from the user and resized such that the angular size is identical for all distances (a). The sphere in setting III is positioned 15 cm above the table and stays fixed on top of the visual marker when the participant moves (b). These screenshots are 2D projections which do not reflect the field-of-view and depth perception of a participant in augmented reality (AR).
