We measured the reaction time to detect a circle (0.6deg arc in diameter), presented for 0.5msec on two dimensional still and motion pictures, and the frequency of response errors to oversight it. The pictures were views of shore which was videotaped from a deck in the small boat, whose vessel speed was 0, 5, or 18kt, at two different sea roads (near scenery and far scenery). Ten observers viewed the pictures projected on a big screen (27deg arc x 43deg arc) with the intention to simulate the navigation of the small boat. The results showed that 1) the reaction time for the still picture was less than those for the motion pictures and 2) the percentage of the oversight of the stimulus in the motion picture of near scenery with the highest speed was much higher than those in other pictures. Some implications of these results on the role of visual attention during the navigating are discussed.
