INVESTIGATION OF NATURAL MOVEMENTS IN AZIMUTH AND ELEVATION LEVER CONTROL ADJUSTMENTS FOR HORIZONTAL AND VERTICAL POSITIONS

摘要

This study was designed to:n1、Determine population stereotypes or “natural” movements involved in the operation of levers designed to control Elevation and Azimuth movements.n2、Determine in which plane levers should be placed to better effect control;i.e., the HORIZONTAL or the VERTICAL plane.nThe results indicated that there is a consistent relationship between RIGHT and LEFT control movements and RIGRT and LEFT movements of a display in both the HORIZONTAL and VERTICAL positions. However, the major finding was that there is no such consistency or “natural” movement or population stereotype with vertically positioned lever controls which move FORWARD and BACKWARD when these controls are associated with an UP and DOWN display movement.nThe HORIZONTAL control position was found to be more conducive to better performance although the VERTICAL control position was preferred by most subjects.
