About

Holger Langer’s research centers on human-robot interaction, user experience (UX) design, and the integration of psychological needs into technology development. His major contribution lies in bridging the gap between abstract user-centered design principles and practical, need-driven design processes—particularly for robotic systems like shopping assistants. In his most-cited work, “Positive User Experience: Novices Can Assess Psychological Needs,” Langer demonstrates how non-experts can effectively evaluate psychological needs within the design cycle, challenging traditional reliance on expert-only assessments. This work builds on his earlier critical analysis of DIN EN ISO standards, where he questioned how truly “human-centered” current design frameworks are. Though his citation count (3 for his top paper) reflects an emerging career, Langer’s impact is notable for advancing a more inclusive, novice-friendly approach to UX evaluation—a shift that could democratize design feedback in robotics. His ongoing efforts to operationalize psychological needs in real-world contexts mark him as a thoughtful advocate for user empathy in technology, making his research particularly relevant for students and practitioners seeking to humanize autonomous systems.
