Approximate play scene of the task.
Area 1: status of the character controlled by participants (i.e., skill cooldown time and remaining health points). Area 2: mini-map showing the overall flow of the task. Area 3: main play area of the task. Area 4: play time and score.

Normalization of the gaze movement.
(A) Four markers are attached to the monitor. (B) Example of a gaze position.

Example of the gaze movement and the distance between the center of the monitor screen and the center of the heatmap.
(A and B) Examples of gaze movement during the task. Each black dot shows the location of the gaze movement on the monitor. The heatmap shows the density of the gaze position (red: higher density of the gaze position; blue: lower density of the gaze position. (A) Center of the monitor screen. (B) Distance between the center of the heatmap and the center of the monitor. (C) Center of the heatmap. The values of the x-axis and y-axis are calibrated using a number between 0 and 1 based on the actual monitor size. (C and D) The average distances (center of the monitor and center of the heatmap) of the expert and low-skill players. The bar shows the average distance (center of the monitor and center of the heatmap) of expert and low-skill players. The error bars represent the standard deviation (SD) of each value.
Fig 4.
Standard deviations (SDs) of the horizontal and vertical gaze movements.
The error bars indicate the between-participant SDs of the individual values. The significance level was set at *p < .05.

Each graph indicates the percentage of fixation in each area.
Fig 6.
The bar plots show the average fixation duration (A and D). (B and E) The average within-participant SD of the fixation duration. Error bars indicate the between-participant SD of the individual values. The significant levels were set at *p < .05 and **p < .01.
