You have an innovative idea and are looking for an interaction concept to make it fly. Or maybe you want to optimize the Human-Machine-Interface (HMI) of an existing product. No problem! We can help you make this happen.

We systematically examine how your product performs in the customer test against that of your competitors. This will help us to understand the strengths and weaknesses of the current concept and to develop a specific user-friendly solution.


Then we go deeper into the functionality of the system in order to translate all use cases into corresponding operating steps. Finally, the entire dynamics of the interaction is illustrated and presented in story boards, which describe a complete operating scenario.


HMI Concept Development

  • Information Architecture

    Information Architecture defines the distribution of functions, information and control operations on displays and switches. This is how we build an understandable HMI in which your users can find their way around.

  • Ergonomics

    Ergonomic assessments and consultations are conducted in line with the relevant standards (e.g. ISO and DIN). These assessments include a detailed analysis of reachability of controls, readability of displays and accessibility for abled-bodied and/or people living with a disability.

  • Wireframes

    The interaction design illustrates and defines the logic of an operation. In wireframes, we can show what happens on the screen as a response to an action (e.g. pressing a button). Doing a good job here ensures the product can later be intuitively understood by the customer.

  • Interaction Design

    Translation of the interaction concept and wireframes into an attractive and ergonomic Visual Design and Sound Design are your product’s calling card. This is one of the key factors creating a feel for the quality of your product and the motivation to buy.




We make all ideas and concepts tangible. That is why we build prototypes with partial or full functionality. We integrate the controls and use them to manage the dialogues on the display. If necessary, we can also produce specific moulded parts in 3D

You can determine the extent of integration of the HMI concept solutions. Depending on how extensive you want to test, you can choose from: stand-alone solutions with a simulated user environment (such as a driving simulator for transportation HMIs) to complete “Client Hardware Integration” where the HMI prototype controls your function in a real environment.




We carry out qualitative and quantitative studies which allow your concept to be put through its paces by test users.

These can be done in a simulated or real environment. The endurance test includes gathering objective data, such as time on task as well as error rates. These findings are complemented with subjective data obtained through interviews conducted for the assessment of usability
and product acceptance.

This forms a valid basis for your final production decisions and leads to the ultimate success of your product.
