VISUAL SEARCH WHILE CLIMBING OR DESCENDING THE STAIRCASES AT A SUBWAY STATION

Experiments were conducted concerning fixation movements while climbing or descending the staircases at a subway station. In climbing or descending, fixation movements differed, but tended to occur near the stairs and at occluding edges of floor or walls, and were greatly changed depending on if they were visible or not. When climbing the staircases, fixation also changed depending on where the subject was located at the stairs, whether making a turn or walking straight at landing. Fixation movements on the occluding edge, blocking off the turn following immediately after the stairs, inform us the danger that exists.
