Design Principles for Effective HMI Display Screen Layouts


Design Principles for Effective HMI Display Screen Layouts


In today's digital age, Human-Machine Interfaces (HMIs) have become an integral part of various industries. From automotive and aviation to manufacturing and healthcare, HMIs play a crucial role in providing a user-friendly interface for controlling complex systems. One of the key elements of an HMI is the display screen layout, which greatly impacts the user experience and functionality. In this article, we will explore the design principles for creating effective HMI display screen layouts. These principles will help designers maximize efficiency, usability, and user satisfaction.

Understanding User Tasks and Workflows

Before delving into the design principles, it is vital to understand the tasks and workflows of the intended users. By gaining a deep understanding of the users' needs and the tasks they need to perform, designers can create intuitive and efficient HMI display screen layouts.

1. Defining User Goals and Objectives

The first step in designing an effective HMI display screen layout is to define user goals and objectives accurately. Identifying what users are trying to accomplish through the interface will allow designers to prioritize information and controls on the screen accordingly. Conducting user research and usability testing can help gather insights and ensure the design meets user expectations.

2. Analyzing Workflows

Analyzing the workflows involved in using the HMI is crucial for creating an efficient display screen layout. By mapping out the sequence of tasks and interactions, designers can determine the optimal placement of information and controls on the screen. This analysis also helps identify potential pain points, allowing designers to find solutions that streamline the user experience.

Guidelines for Effective Display Screen Layouts

Once the user tasks and workflows are understood, designers can follow several key guidelines to create effective HMI display screen layouts. These guidelines ensure that information is presented clearly, controls are easily accessible, and the overall user experience is seamless.

3. Visual Hierarchy

Establishing a clear visual hierarchy is essential in HMI display screen layouts. By organizing information based on importance and relevance, users can quickly locate and interpret the displayed data. Designers can achieve visual hierarchy through techniques such as varying font sizes, colors, and whitespace. Emphasizing critical information while de-emphasizing less important elements helps users focus on what matters most.

4. Grouping and Alignment

Grouping related elements and aligning them cohesively helps users perceive relationships and reduces cognitive load. Designers should group information and controls that are functionally related, making it easier for users to locate and interact with them. Consistent alignment and the use of grids create a visually pleasing display screen layout, enhancing user comprehension and efficiency.

5. Consistency of Controls and Symbols

Consistency plays a vital role in creating an intuitive HMI. Users expect controls and symbols to have consistent meanings and behaviors throughout the interface. Designers should adhere to established industry standards and conventions, making sure that controls and symbols are familiar and easily recognizable by users. This consistency reduces the need for users to learn new interactions repeatedly, enhancing usability and reducing errors.

6. User-Friendly Navigation

Efficient navigation is critical for users to move seamlessly through different screens and functionalities. Designers should provide clear navigation paths, ensuring easy access to various sections of the HMI. Intuitive icons, breadcrumbs, and menus can aid users in understanding their current location within the interface and how to navigate to desired destinations.

Optimizing Display Screen Real Estate

With the limited screen real estate available in HMIs, designers must optimize the use of space to present information effectively without overwhelming users.

7. Information Density

Finding the perfect balance between information density and readability is crucial in HMI display screen layouts. Designers should present information that is relevant to the user's current tasks while avoiding clutter. Using appropriate font sizes, spacing, and visual cues, designers can maximize the display of information without sacrificing legibility and comprehension.

8. Progressive Disclosure

Progressive disclosure is a design technique that reveals information gradually, only when needed. This technique allows designers to present essential information prominently while keeping additional details hidden until requested by the user. Progressive disclosure prevents information overload, enabling users to focus on immediate needs and reducing cognitive load.


Effective HMI display screen layouts are crucial for enhancing user experience, usability, and overall system efficiency. By understanding user tasks and workflows, following design principles, and optimizing display screen real estate, designers can create intuitive and efficient HMIs. These principles, when applied thoughtfully, result in interfaces that empower users, improve productivity, and minimize errors. Designers must continuously gather user feedback and iterate on their designs to ensure an optimal experience for users interacting with HMIs.
