MOUNTING ANGLE OF A VJ REMOTE RADAR INDICATOR AND ITS EFFECT ON OPERATOR PERFORMANCE.
Abstract
A VJ remote radar indicator was mounted at seven angles (scope-face with respect to the floor: 0, 15, 30, 45, 60, 75, 90 degrees) and tests were made to discover whether there is an optimum mounting angle for operator performance. The results of the experiment show that the angle at which a VJ is mounted has no significant effect on an operator's speed and/or accuracy in target indication. A questionnaire was given to the group of subject-operators used in the experiment to determine which mounting angle they preferred. An analysis of these results gave the following rank order (from most to least preferred): 15, 45, 30, 60, 0, 75, 90 degrees. The 0 degrees position is the conventional mounting angle. (Author)
