Outline of the verification process used with the eye-tracking method. Coordinates (x, y) on the large screen were set up upper left (0, 0), lower left (0, 960), and upper right (1280, 0). Fixation and saccade were judged from the viewpoint coordinates (px) on the x and y axes obtained by the eye tracker. We analyzed a series of processes, from confirming the dispensing information in the prescription area (40 cm × 160 cm) to pointing at the target spot in the drug rack area (80 cm × 160 cm)
