Experiments were conducted on 23 subjects using actual controllers in order to study direction-of-motion stereotypes for rotary control. The results of these experiments showed on the whole strong stereotypes for each control side with the exception of the bottom side, in the following relationships: 1) for the semi-circular indicator, when the rotating indicator (except the downward pointing semi-circular indicator) and the control were moved in the same direction, 2) for the geometric figure, when the control was moved clockwise in response to an indicator moving to the right, and counterclockwise in response to one moving to the left, 3) for the bar indicator when the control was moved clockwise in response to an upward pointing horizontal indicator sliding to the right, and counterclockwise in response to one sliding to the left; additionally, there were strong stereotypes for some left hand controls in response to an upward pointing vertical indicator moving downward. In these strong stereotypes positive reversibility were observed. On the other hand for controls located on the bottom side only one instance of strong stereotype and negative reversibility were found.
