English: Video showing administration of the trail-making test Part B using the eye-tracking equipment. The subject’s head is apposed comfortably in the frame at a fixed distance from the screen. The target being fixated turns red and its border fades to grey to denote successful sequencing. As the camera pans to the left, the administrator’s screen is seen which shows the subject’s progress, followed by a screen showing the position of visual fixation at any moment as a white moving cursor.
