Thus, in addition to effective, efficient and easily accessible use, the promotion of human health and well-being is ensured.

Key Value Propositions of our approach:

  • Cutting Edge HMI-Solutions
  • Quick Wins for the User
  • Resilient Marketing Claims
  • Secured Management Decisions
  • Project Management Support

Innovation process

Understand and plan
human-centered Project Goals


The foundation of effective, human-centered development is a shared understanding of the strategic Thrust of development activities. The most important thing here is to clarify relevant Constrains and define coordinated roles & interfaces between all players in the entire Project Team.

The main activities include:

  • Delimitation and containment
  • Time factors and budgets
  • Responsibilities

You want your usability project to be in competent Hands and thus support the project management?
We take care of the necessary framework conditions.

ind insights and connections by means of
User Research & Application Analysis

Application Analysis

The primary goal is to gain comprehensive knowledge and understanding of the products Context of Use. Initially, however, the focus of analysis is primarily on the recording of handling Situations, body postures and movements, right through to the identification of user needs.
By means of a task-based approach (task analysis) and the use of suitable testing and measuring equipment, these findings range from recorded working postures to motion sequences (e.g. forces to be endured & joint angles) to cognitive processes (e.g. intuitiveness & cognitive usability).
This in combination with ergonomic criteria such as the demographic & ethnographic classification of users (e.g. in anthropometry & human performance) enables the definition of HMI quality.

The main activities include:

  • On-Site Observations
  • Expert-based ergonomic Analyses
  • Hand Pressure Mappings
  • Body- & Motion Tracking
  • Muscle activity Measurements (EMG)

Are you looking for a sound Basis to improve your product through the correct & early inclusion of users and their needs?
We provide you with the right access to the user world.

Leveraging optimization potentials through
Synthesis & User Interface Specification

Interface Specification

The condensation of information already gained from human-centered development activities is essential for the clean derivation of specifiable Design Requirements (so-called User Interface Specifications).
These represent the result of identified Optimization Potentials of investigated human-machine interfaces.
Load-stress assessments can be used, for example, to optimize the comfort of pressure distribution or to improve controllability.
Whether control elements or handles, each user interface can thus be ideally adapted to the user and the application through targeted Design Parameter Adjustments.

Key findings include:

  • HMI Design Recommendations
  • User Interface Specifications
  • Usability Problems
  • HMI Strengths & Weaknesses

Do you need the concrete HMI Optimization Potentials of your product to plan future development activities?
Whether ergonomic quick win or visionary product innovation, we show the way.

Generate Inspired and inspiring
generate innovative Ideas


Whether User researcher, HMI Designer or Usability Engineer, each role in the human-centered product development team can generate the decisive solution idea.
That's why we rely on the Interdisciplinarity of our entire team, especially in creative development phases - and with demonstrable success.
Because the sustainable development of great and innovative Products is only possible through team creativity, which optimally plays off the strengths of each discipline.
In ideation phases, we create creative spaces for our development teams through workshops, methods and guidance in order to tap into these strengths - and we would be happy to do so with you. Whether it's a clever Micro-Innovation of a control element or an innovative Operating Concept, we always measure ourselves against the applicability of the solution from the user's point of view.

The main activities include:

  • Mind-Sketching
  • Intuitive Prototyping
  • Interaction Design Workshops
  • Usability Outside of the Box
  • Engineering meets Design Sessions

You want a creative Partner who not only designs HMI ideas for the presentation drawer?
Together we create HMI concepts for which we are always accountable to users and customers.

Truly experiencing ideas is the purpose of
Prototyping & Concept Design


In compact Pretotyping and Prototyping Sprints, we efficiently and effectively generate a tangible decision-making Basis for previous concept ideas.
Our particular claim is to generate the adequate HMI Fidelity as quickly as possible and with conscientious use of resources, in order to enable a resilient decision-making basis for the existing Design Options for the entire project team.
For both physical and digital HMI concepts, our expertise coupled with the latest Prototyping Tools enables true added value in this crucial phase of human-centered product development - and all this at USE-Ing. in-house.

Our key prototyping tools include:

  • 3D Printer for Handles, Actuators & Mechanics
  • Laser Cuter for Packaging & Supporting Structures
  • Electronics & Electromechanics for Displays & Interactivity
  • Digital Prototyping Tools & Click Dummies
  • Interaction Design Simulations in VR & AR

You need competence and guidance in "bringing potential product innovations to life"?
We are your partner for the right prototypical implementation of HMI concepts.

User and expert-based


Our experts at USE-Ing. act as an objective partner for the evaluation of the ergonomic interface quality of your products or product concepts in our Usability & Ergonomics Test Laboratory.
Similar to analytical phases, methods are used to objectively Measure Human Factors parameters.
Our review activities focus primarily on the comparison of the HMI properties with the defined user interface requirements, ergonomic acceptance criteria, as well as ergonomic and normative guidelines and recommendations.
If it is necessary for product development to obtain valuable real-world feedback on usability through user evaluations, we are happy to conduct usability tests in one of our laboratories or on-site.
The goal is to ensure transparency about the current quality of the product HMI for the entire project team. For this reason, USE-Ing. also acts to certify Product ergonomics.

The main activities include:

  • Regulatory and normative Alignment
  • Force and vibration Measurements
  • Interaction Simulations
  • Analyses of Macro- and Microergonomics
  • Ergonomic Certifications

You need a reliable Statement about your product ergonomics or usability, or for strategic Marketing Claims?
We evaluate and certify the ergonomics and usability of your product.
