Perceiving and controlling simulated ego-rotations by optic flow: Influence of field of view (FOV) and display devices on ego-motion perception

Generally, all target angles were undershot (see Fig. 3). For turn error as the dependent measure, a 3 (visualization conditions) × 5 (target angles) × 4 (velocities) × 2 (turn directions) repeated-measures ANOVA showed the following results: The effect of visualization condition was significant, as well as target angle. The presentation order of the three conditions had no significant effect (see Table 1). Bonferroni-corrected post-hoc tests revealed significant differences between the full screen and the HMD (p<0.001), and also between HMD and blinders (p<0.01), but not between screen and blinders (p=0.407). Thus, FOV did not affect performance on the projection screen. The interaction between visualization condition and target angle was also significant (see Fig. 3).
