”Creative & Purposeful - A strong team is the driver for success“

USE-Ing. (spoken like the English word for "use") stands for usability engineers and at the same time expresses that our focus is always on representative users and their interaction with various technical products in the respective context of use. The scientific background of the USE-Ing. GmbH makes it possible to transfer the latest findings of human-machine interaction research into industrial practice. USE-Ing. was founded in 2017 as a spin-off of the research and teaching area "Technical Design" of the University of Stuttgart and was founded in response to the high industrial demand for the integration of representative users into the product development process. Today, USE-Ing. successfully supports companies in the medical technology, aeronautical engineering, software engineering, mechanical engineering, mobile machinery and geronto-technology sectors in the human-centered technology development of interactive systems.

Dr. Julia Moritz

User Researcher

Dr. Julia Moritz, who holds a doctorate in psychology, is a user researcher at USE-Ing. GmbH, Julia Moritz is responsible for all topics concerning test person studies, usability evaluations and user integration into the product development process.

Her focus is on the planning and conception of study contents and procedures, the acquisition of representative test participants and the execution of the studies. Besides formative and summative usability evaluations, the integration of users into the design process is a typical use case.

In her scientific research she investigated how the use of interactive operating functions makes it possible, to present spatial information according to the situation and needs. It continues to participate in scientific and industrial research through regular publication of research results in national and international journals and congresses.

Would you like to involve your users in product development?

She brings your target groups on board and supervises the implementation of the study for you.

Stephan Mayer (M.Sc.)

Usability Engineer

Stephan Mayer is a usability engineer at USE-Ing. GmbH, responsible for product development and human-machine interaction.

With his master's degree in engineering and his strong specialization in HMI design and usability engineering, he brings deep understanding and enthusiasm to human-centered product development. His roots as a trained technology manager help him to keep an eye on the field of tension of a holistic product development.

From the implementation of ergonomic workstations in production, to the close-knit design of human-robot collaboration, to the fine design of hand grips on hand-held machines, he has already contributed and demonstrated his experience in a wide variety of fields.

He invests his creativity in innovative ideas and likes to think outside the box.

He follows this path with you until the successful product launch.

Santiago Pecha (M.Sc.)

User Interface Designer

At USE-Ing. GmbH, user interface designer Santiago Pecha is responsible for the design of human-machine interfaces.

In doing so, he draws on his expertise in both industrial design and interaction design, which he has honed through his international studies and numerous successful projects.

The development of user-centered, innovative concepts thus flows through his capable hands to fully mature the usability and user experience of physical and digital interfaces.

He understands the complexity of product design, which, in addition to pure ergonomics and usability, brings the product and the associated operating concept closer to the user through adequate emotionality. At an early stage in the development process, he attaches importance to the sensible degree of interface prototype fidelity and to making it possible to experience the product through the necessary design dimensions of form, color, materials and surfaces.

He uses the skills required for this for the benefit of optimal user-centered product development.

You want a tangible interaction concept through low or high fidelity prototypes?

He creates HMI solutions for you, which will inspire your customers and users.
