Users in immersive virtual environments (VEs) with head-mounted displays (HMDs) often perceive compressed egocentric distances compared to the real world. Although various factors have been identified that affect egocentric distance perception, the main factors for this effect still remain unknown. Recent experiments suggest that miscalibration of the field of view (FOV) have a strong effect on distance perception. Unfortunately, it is not trivial to correctly set the FOV for a given HMD in such a way that the scene is rendered without mini- or magnification. In this paper we test two calibration techniques based on visual or visual-proprioceptive estimation tasks to determine the FOV of an immersive HMD and analyze the effect of the resulting FOVs on distance estimation in two experiments: (i) blind walking for long distances and (ii) blind grasping for arm-reach distances. We found an impact of the FOV on distance judgments, but calibrating the FOVs was not sufficient to compensate for distance underestimation effects.
