Effects of a Pitched Field Orientation on Hand/Eye Coordination

摘要

Ten subjects judged eye level by making verbal and pointing responses while looking into a box that was pitched at angles of approximately -15,-7.5,0,7.5 and 15 degrees. The mean verbal judgement changed as a function of the box's pitch angle according to the relationship: Judged Eye Level = 0.48 (Box Pitch 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 responses change at approximately 40 percent of the rate of the perceptual responses, as indicated by the verbal judgements, and are in the opposite direction. These errors have implications for the design of displays and controls for vehicles that operate in environments where pitched visual fields are encountered.
