Movement Compatibility for Rotary Control and Digital Display

— Using real mechanical controls, this experiment studied strength and reversibility of direction-of-motion stereotypes and response times for different configurations of digital display and rotary control. The effect of instruction of change of number direction (I) and control plane (P) on movement compatibility was analyzed with precise quantitative measures of strength and reversibility index of stereotype. A comparison between the results obtained in this experiment with that of rotary controls and circular display was made. There was similarity in the results of the two tests that both setups contain strong and reversible stereotypes. It was demonstrated that strong and significantly reversible clockwise-for-clockwise (CC) and anticlockwise-for-anticlockwise (AA) stereotypes were found with the use of circular display, and strong clockwise-for-increase (CI) and anticlockwisefor-decrease (AD) stereotypes were found with the digital display. Subjects’ response times were found t...
