Figure 3. Final pointing position as a function of conditions and angles of tilt.

a) Single conditions (S_fwd, S_bwd and B_fwdS) relative to the angle of tilt. b) Combined conditions (B_fwdS_bwd and B_fwdS_fwd) relative to the angle of tilt. Symbol positioned below a given value of a specific angle and condition represents a statistical difference with 0 deg in this specific condition (*: p<.05; ‡: p<.01; †: p<.001). Note that final positions are also statistically different for B_fwdS_bwd between 6 deg vs. 12 deg or 18 deg (p<.001 and p<.01, respectively) and for B_fwdS_fwd between 6 deg vs. 18 deg (p<.01). Conditions are illustrated on the right side of each figure with pink lines representing the scene orientation (N.B., scene depth distance was not at scale). Vertical bars denote positive standard errors.
