Results of Experiment 4. The same box positions have been tested at the same pointing zones, but differed in the wall orientation (a) versus (e) or (d) versus (h). Dashed gray lines indicate walls that appeared after the participant left the start zone. (b) Pointing errors are plotted for all the paired conditions with an ‘East-West’ wall versus the corresponding condition with a slanted ‘North-West’ wall (pointing from at zone C). (c) Similar comparison but now for a ‘North-East’ wall and pointing from zone E (emerald diamond). (f) Histogram of pointing differences between paired trials for the two different wall orientations pointing from zone C. (g) Same for zone E. (i),(j) show the same as (f),(g) respectively, except that they plot pointing differences with respect to the projection-plane model rather than with respect to ground truth. See Fig S1 for numbered list of scene configurations.
