Industrial HMI Design and Operator Experience: UI/UX Discipline on Factory Floors
Operators who effortlessly navigate smartphones in their daily lives often struggle with industrial machine panels, not because of a lack of technical skills, but because of poor HMI design and cognitive overload. When interface design is neglected during automation commissioning, screens become cluttered with disorganized buttons, jarring colors, and data dumps. This practical guide outlines key engineering principles for reducing cognitive load, establishing a consistent design system, enforcing alarm discipline, and structuring role-based screen architectures on the factory floor.
