Institute for Experimental Psychophysiology

The Institute for Experimental Psychophysiology (IXP) is a private research institute and scientific consultancy based in Düsseldorf, Germany. Founded in 2014 as a spin-off from the University of Wuppertal by Prof. Dr. Jarek Krajewski and Prof. Dr. Sebastian Schnieder, IXP operates at the intersection of academic research and industrial application. Its mission, "Measuring the Impossible," reflects a focus on objectively capturing emotional, cognitive, and health-related aspects of human–technology interaction using multimodal sensors and AI-driven analysis. IXP provides a range of services including experimental user studies, technology scouting, dataset engineering, and the development of affective computing demonstrators. The institute specializes in psychophysiological methods such as EEG, ECG, EMG, EDA, and thermal imaging, combined with computer vision, audio signal analysis, and machine learning. Its work spans domains such as driver state detection, social robotics, digital health, human factors, and chronobiological lighting. Since 2015, IXP has been located in the center of Düsseldorf, where it operates laboratories and living-lab facilities. The institute serves both academic and industrial partners, offering scientific consulting, product evaluation, and research-on-demand services. Its founders continue to lead the organization as owners and CEOs, ensuring close ties to academic rigor and methodological expertise.

The Institute for Experimental Psychophysiology (IXP) was founded in 2014 as a spin-off from the University of Wuppertal by Prof. Dr. Jarek Krajewski and Prof. Dr. Sebastian Schnieder. Both founders brought academic expertise in psychophysiology and affective computing to the venture, aiming to bridge the gap between scientific research and industrial application. Since 2015, IXP has been headquartered in the center of Düsseldorf, Germany, where it established offices and laboratories. The institute's mission, "Measuring the Impossible," encapsulates its focus on developing and applying state-of-the-art affective computing methods. These methods rely on audio, video, and biosignal sensors to objectively determine and optimize emotional, cognitive, and health aspects of digital products. Over the years, IXP has built a portfolio of services including experimental user studies, technology scouting, dataset engineering, and the creation of proof-of-concept demonstrators for affective computing. IXP has engaged in projects across various domains, such as aircraft cabin lighting simulation, driver state detection, social robotics, and digital health. The institute emphasizes high methodological expertise, particularly in digital health and human–technology interaction, and offers scientific consulting and research-on-demand services to partners of all sizes. Its founders continue to lead the organization, ensuring a strong foundation in academic rigor and innovation.
