UI/UX Design

UI/UX design for industrial products & special vehicles

Intuitive operation. Maximum security. Measurable efficiency.

We develop user interface concepts for human-machine interfaces in mechanical engineering, medical technology, SaaS applications, apps, and special vehicles – so that complex technology is operated reliably, safely, and efficiently.

✔ Reduced operating errors
✔ Faster onboarding
✔ Higher process reliability
✔ Stronger product differentiation

In doing so, we consider the software interface and, if necessary, the hardware control interface as well. We pay equal attention to ease of use, a positive user experience, and ergonomics.

From the initial idea to the finished product, we design solutions following the proven method of usability engineering according to DIN ISO 9241.

HMI solutions for complex products and industries

Each industry has specific requirements for control concepts. We develop HMI and UX solutions that work in real-world applications – technically, ergonomically, and contextually appropriate.

Good UX/UI design is a crucial success factor

A well-thought-out design not only makes products more user-friendly but above all, economically more successful. An intuitive and professionally designed HMI (Human-Machine Interface) offers decisive advantages:

Efficiency & Security: It helps to avoid operating errors, accelerate work processes, and significantly increase user safety.
Economic efficiency: It increases customer satisfaction, reduces support effort, and gives you a clear competitive advantage.
Easy operation: It ensures a shorter onboarding time and higher acceptance among users.

But many interfaces are designed technically—not user-centered.

We translate technical complexity into intuitive interaction.

Our design process

User-centered. Holistic. Validated.

Our work is based on the human-centered design process.

We consistently put the user at the center of our work—while also taking ergonomics, technical requirements, and your brand identity into account.

This results in interfaces that are secure, intuitive, and economical.

Iterative & low-risk

We develop iteratively and validate concepts early on with prototypes.
The final design is only developed after successful validation.
This reduces development risks and saves on later adaptation costs.

Interdisciplinary & practical

Our interface designers work closely with your application and development teams.

This is how we combine:

Technical expertise
Intuitive user guidance
Future-proof interface design

The result: robust, implementable solutions with high acceptance.

UX 720° - Rethinking HMI Design

We design all relevant interfaces of your product – integrated and coordinated:

Physical controls like buttons, rotary knobs, or joysticks
Reach and service areas
Touch and display interfaces
Digital software interactions

Especially with complex machines, special vehicles, or technical systems, this integration is crucial.

We call this holistic approach UX720° – because we consider interaction completely and across systems.

Operator HMI

Complex technology. Easy to operate.

With increasing system complexity, intuitive, ergonomic user interfaces become a critical success factor. Short training periods and low operation errors ensure efficiency, safety, and profitability.

We develop modern Operator HMIs that represent technical functions in a structured and understandable way.

Through the close collaboration of Industrial Design and UI/UX, robust, powerful, and intuitive interfaces are created – for machines, special vehicles, and technical systems.

Optimal user experiences in medical technology

We support you in the normatively prescribed implementation of usability of Medical products according to DIN EN 62366-1.

We create precise use specifications and user interface concepts for you, carry out the necessary risk analyses, and validate your product in formative as well as summative testings. Every step is carefully planned, evaluated, and used to optimize the final design of your medical device.

From individual role to team player: UX done right

Many companies still place UX as an individual role in marketing, thereby squandering enormous potential. In the product context, good User Experience arises only in an interdisciplinary team and plays a crucial role in efficiency and quality in development. Why this is and what role external partners play is shown in the full article.

VR and AR in product presentation: bringing products to life digitally

VR and AR open up new ways of presenting products: products can be experienced digitally, complex content becomes understandable and variants can be compared directly – either without physical prototypes or in combination with them. At BUSSE DESIGN+ENGINEERING, we use immersive VR and AR solutions to make trade fairs, sales, showrooms and decision-making processes more efficient and vivid.

Corporate User Experience (CUX)

Corporate user experience is not a cosmetic exercise, but a strategically effective corporate management tool. In a world where users switch between touchscreens, hard keys, voice inter-faces and apps, a consistent CUX creates trust, recognizability and efficiency - across all prod-ucts and touchpoints.
