Why is good UX/UI design a decisive factor for success?

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

Efficiency & safety: It helps to avoid operating errors, speed up work processes, and significantly increase user safety.
Cost-effectiveness: It increases customer satisfaction, reduces support costs, and gives you a clear competitive advantage.
Ease of use: It ensures a shorter training period and greater acceptance among users.

Our interface designers and usability experts work closely with your application experts. This ensures that creative design, intuitive user guidance (usability), and forward-looking trends are optimally combined.

An iterative approach is a matter of course for us. After each loop, we evaluate the results together. To save on later development costs, we ideally only start

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° – HMI design taken to the next level

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

Physical controls such as buttons, rotary knobs, or joysticks
Grip and service areas
Touch and display interfaces
Digital software interactions

This integration is particularly crucial for complex machines, special-purpose vehicles, or technical systems.

We call this holistic approach UX720° – because we view interaction as comprehensive and cross-system.

Operator HMI

Komplexe Technik. Klar bedienbar.

Mit steigender Systemkomplexität werden intuitive, ergonomische Bedienoberflächen zum entscheidenden Erfolgsfaktor.
Kurze Einarbeitungszeiten und geringe Fehlbedienungen sichern Effizienz, Sicherheit und Wirtschaftlichkeit.

Wir entwickeln moderne Operator HMIs, die technische Funktionen strukturiert und verständlich abbilden.

Durch die enge Zusammenarbeit von Industrial Design und UI/UX entstehen robuste, leistungsstarke und intuitiv bedienbare Interfaces – für Maschinen, Sonderfahrzeuge und technische Anlagen.

Optimal user experience in medical technology

We support you in the normative implementation of the usability of medical devices in accordance with DIN EN 62366-1.

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

Developed with the user in mind – We are auditors at the UIG

This year, we became a member of UIG e.V. (Usability in Germany), an association that promotes the integration of user-centered development in organizations.

The “User-Centered Development” seal was created specifically for this purpose. The seal is intended to help medium-sized companies obtain visible proof of the successful establishment of a user-centered development process. And we at BUSSE Design+Engineering are auditors for this seal, enabling our customers and interested parties to obtain proof of intuitively operable products.

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.

Operator HMI Lab at the HfG

Is it possible to develop a complex user interface consisting of hardware, electronic and software components in just one week? Students at the HfG Schwäbisch Gmünd have proven that it is. In just a few days, they designed, tinkered, drew, modelled and built their creation.

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.

Accessibility

Whether in a vehicle, on a medical device or on a touch panel in building technology: we encounter human-machine interfaces (HMIs) everywhere - often in the form of specialised displays or operating elements that are not based on classic operating systems.
