Figure 3.

A sample gaze and waypoint time series from a single participant. Top panel: Horizontal screen positions in respect to CURV-SEG. Gaze tracking is depicted as green points while the yellow lines indicate the saccades that were derived using the NSLR-HMM algorithm. Blue lines indicate the location of WP_const, red the location of WP_alt, and purple the location of WP_prev. Solid lines indicate the WP in question is visible, whereas dashed lines indicate that it is missing/virtual. WP_const is always visible except when CURV-SEG = 9 and the MISS condition does not apply. WP_alt is only visible when CURV-SEG = 9 and the VIS condition applies. WP_prev is visible when the previous WP_const (CURV-SEG $\ne$ 9) or WP_alt (CURV-SEG = 9) is visible. In the sample times series, the sienna-colored sections highlight the MISS manipulations and the cyan-colored sections highlight the part of the VIS condition that was included in the data analysis (i.e., when the furthest WP is visible and the last three WPs have all been visible). Bottom panel: Same as top panel but with vertical positions depicted instead.
