Ten subjects eye level by making verbal and pointing responses while looking into a box that was pitched at angles of approximately -15, -7.5, o, 7.5 and 16 degrees. The mean verbal judgements changed as a function of the box's pitched angle according to the relationship: Judged eye level = 0.48 (Box pitched angle) - 0.31 degrees which agrees with the results of previous studies. the mean pointing responses were also a function of the box's pitch angle: pointing response = 0.19 (Box Pitch Angle) - 5.39 degrees. Thus, the mean pointing response change at approximately 40 percent of the rate of the perceptual responses, as indicated by the verbal judgements, and are in the opposite direction. There errors have implications for the design of displays and controls for vehicles that operate in environments where pitched visual fields are encountered.
