Technically powerful products often fail due to usability. We help companies make complex systems understandable, safe, and efficient to use.

UI/UX Design
UI/UX Design for Industrial Products & Special Vehicles
Intuitive operation. Maximum safety. Measurable efficiency.
We develop user interfaces for Human-Machine Interfaces in mechanical engineering, medical technology, SaaS applications, apps, and special vehicles so that complex technology can be operated reliably, safely, and efficiently.
✔ Reduced operating errors
✔ Faster onboarding
✔ Higher process security
✔ Stronger product differentiation
We consider the software interface and, if necessary, the hardware control interface. We pay equal attention to easy operation, a positive user experience, and ergonomics.
From the initial idea to the finished product, we design solutions according to the proven method of usability engineering in compliance with the DIN ISO 9241 standard.

Typical challenges in HMI & user interface concepts
HMI solutions for complex products and industries
Each industry presents specific requirements for user interfaces. We develop HMI and UX solutions that function in real use – 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 also economically more successful. An intuitive and professionally designed HMI (Human-Machine Interface) offers decisive advantages:
Efficiency & Safety: It helps to avoid operating errors, accelerate work processes, and significantly increase user safety.
Economicalness: It increases customer satisfaction, reduces support effort, and gives you a clear competitive advantage.
Easy operation: It ensures shorter onboarding times and higher acceptance among users.
But many interfaces are technically designed – not user-centered.
We translate technical complexity into intuitive interaction.
Contact usOur 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.

Our impulses - additional services with added value
We offer a range of innovative additional services that go beyond classical product development.
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.
To the Operator HMI Impulse pageOptimal usage experiences in medical technology
We support you in the normatively required implementation of the usability of medical products according to DIN EN 62366-1.
We create precise use specifications and user interfaces for you, conduct necessary risk analyses, and validate your product in formative as well as summative tests. Every step is carefully planned, evaluated, and used to optimize the final design of your medical product.

"User-centered developed" - We are an auditor at UIG
We have been a member of UIG e.V. (Usability in Germany) since this year, which promotes the integration of user-centered development in organizations.
Eigens dafür wurde das Siegel „Nutzerzentriert entwickelt“ ins Leben gerufen. Das Siegel soll mittelständischen Unternehmen dabei helfen, einen sichtbaren Nachweis der erfolgreichen Etablierung eines nutzerzentrierten Entwicklungsprozesses zu erhalten. Und wir als BUSSE Design+Engineering sind Auditor für dieses Siegel und ermöglichen unseren Kunden und Interessierten einen Nachweis für intuitiv bedienbare Produkte zu erhalten.
Ich möchte mein Produkt zertifizieren lassenOur services
Our UI/UX designs are based on the Human Centered Design Process (DIN 9241). The result is error-free and user-friendly products that guarantee an effective, efficient, and satisfying user experience.
We consider the entire user experience – from the first interaction to post-use service. Your guarantee of the highest quality is our proven expertise in usability engineering for highly regulated areas such as medical technology.
To achieve these goals, we rely on the following components:
