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

USE-Ing. stands for usability engineering. It expresses our passion for designing techology for and with professional 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 created 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.
