The Worringham and Beringer 'visual field' principle for rotary controls

Area of Science:

• Human-Computer Interaction
• Ergonomics
• Machine Design

Background:

• Compatibility between control input and display output is crucial in machine design.
• The Worringham and Beringer principle (1989, 1998) established compatibility for horizontally moving controls with displays in different planes.
• Previous research highlighted the importance of aligning operator's visual field with control-display relationships.

Purpose of the Study:

• To demonstrate the applicability of the visual field principle to vertically moving translational controls and rotary controls.
• To extend the Worringham and Beringer principle to a wider range of control types.
• To provide a comprehensive design principle for optimizing control-display compatibility in non-coplanar configurations.

Main Methods:

• Analysis of past data from the current authors.
• Experimental validation of the visual field principle across different control types (horizontal, vertical, rotary).
• Comparison of operator performance and compatibility metrics under varying control-display plane configurations.

Main Results:

• The visual field principle was shown to be operational for vertically moving translational controls.
• The visual field principle was also demonstrated to be effective for rotary controls.
• These findings extend the original principle, confirming its broad applicability.

Conclusions:

• The visual field principle is a powerful and versatile design guideline for non-coplanar control-display systems.
• Its application ensures high compatibility across horizontal, vertical, and rotary controls.
• This principle significantly enhances operator performance and reduces errors in diverse machine interfaces.
