HMI Touch Screen Panel Design Best Practices


HMI Touch Screen Panel Design Best Practices


As touch screen technology becomes increasingly prevalent in various industries, designing intuitive and efficient Human-Machine Interface (HMI) touch screen panels is crucial. An effective HMI allows users to interact seamlessly with complex machines, improving productivity and reducing user errors. In this article, we will explore the best practices for designing HMI touch screen panels, ensuring a user-friendly experience and optimizing overall functionality.

Understanding User Needs

1. User-Centered Design Approach

To create an effective HMI touch screen panel, it is vital to adopt a user-centered design approach. This involves understanding the needs, goals, and capabilities of the end-users. Engage with potential users through interviews, surveys, and usability testing to gain insights into their preferences and expectations.

2. Task Analysis

Perform a comprehensive task analysis to identify the actions users must perform regularly. This helps determine the most critical functions that should be easily accessible on the touch screen panel. Prioritize these functions and optimize their placement to enhance productivity and efficiency.

Design Considerations

3. Visual Hierarchy

Establishing a clear visual hierarchy is essential for an intuitive touch screen design. Employ size, color, and contrast to emphasize important elements such as buttons, icons, and labels. Ensure that essential functions are more prominent, guiding users' attention effectively.

4. Consistency and Familiarity

Maintaining consistency in the design elements throughout the touch screen panel creates a familiar interface. Consistency contributes to a sense of predictability and reduces cognitive load for users. Use standardized icons, symbols, and terminology to enhance users' understanding and make interactions more comfortable.

5. Intuitive Navigation

Develop an intuitive navigation system by organizing functions and screens logically. Allow users to navigate through the touch screen panel effortlessly, ensuring they can easily find the required information or perform specific actions. Incorporate a well-structured menu hierarchy and provide clear visual cues for navigation, such as breadcrumbs or a back button.

Layout and Interaction

6. Effective Use of Space

Optimize the use of available screen space by carefully balancing elements on the touch screen panel. Avoid clutter by arranging elements with sufficient spacing to reduce accidental touches and improve touch accuracy. Remove unnecessary buttons and information that may distract or confuse users.

7. Touch Target Size and Accuracy

Design touch targets (such as buttons or icons) with an appropriate size to accommodate various finger sizes accurately. Consider the average adult fingertip size of 10-14mm and ensure that touch targets have a minimum size of 9mm. Add padding around touch areas to prevent accidental selections and account for potential slight touch deviations.

8. Feedback and Responsiveness

Provide instant visual feedback to acknowledge user input and actions promptly. Incorporate animations, color changes, or sound effects to indicate that an action has been recognized. Additionally, ensure the touch screen panel responds quickly and accurately to users' touch, minimizing any perceivable lag.

Error Prevention and Recovery

9. Clear Error Messages

When users encounter errors or input mistakes, display clear and understandable error messages. The messages should describe the problem accurately and offer possible solutions to correct the issue. Avoid using technical jargon and provide specific guidance to help users navigate through any errors encountered.

10. Undo and Redo Capability

Implement an undo and redo capability to allow users to rectify mistakes easily. Users should be able to reverse unintended actions without causing any additional errors or negatively impacting their overall workflow. The undo/redo feature provides a safety net and reduces frustration by allowing users to return to a previous state.


Designing intuitive and user-friendly HMI touch screen panels is vital to improving productivity, reducing errors, and enhancing the user experience. By following best practices such as adopting a user-centered design approach, creating a clear visual hierarchy, and incorporating intuitive navigation, designers can develop effective HMIs. Additionally, by considering layout and interaction, offering responsive touch targets, and providing error prevention and recovery features, the HMI touch screen panel becomes a valuable tool, facilitating seamless interaction between humans and machines.
