Virtual environment used during Experiment 3 and Experiment 4. (a) In the HMD, participants viewed an environment depicting a living room with realistic furniture, and a large picture display on the wall at a distance of 2 meters, meant to simulate real-life picture viewing, with vergence remaining inside the VR comfort zone40. The screen covered most of the participant’s field of view. (b) In Experiment 4, each picture depicted on the virtual screen from (a) showed a realistic scene with some furniture and a red ellipsoid. Viewers were instructed to fixate on a specific location (indicated by a green cross) and to judge whether the ellipsoid was wider or narrower than a perfect sphere. Viewing slant and eccentricity were varied across the experiments.
