Laiennutzer

Laiennutzer is a German term that translates literally to "lay user" and refers to people who use software, systems, or technologies without professional training or specialized knowledge. The concept is rooted in the broader distinction between experts and non-experts that has been examined in fields such as ergonomics, human–computer interaction, and information science.

The term emerged in the late 20th century as computer systems proliferated beyond corporate and research settings. In contrast to Fachnutzer (professional users) who rely on software for specific business or scientific tasks, Laiennutzer engage with applications for everyday purposes such as communication, entertainment, or personal organization. Research on Laiennutzer often focuses on usability, accessibility, and interface design to accommodate diverse cognitive and physical capabilities.

In the design of consumer electronics, operating systems, and web services, understanding the needs of Laiennutzer has guided the development of intuitive navigation, context‑aware help systems, and default configurations that minimize user error. Studies have shown that when interfaces align with common mental models, Laiennutzer experience fewer frustrations and higher satisfaction.

Compliance with legal frameworks such as the European Union's General Data Protection Regulation (GDPR) has also prompted companies to ensure that lay users can easily understand privacy settings and consent mechanisms. In education and public policy, initiatives that promote digital literacy target Laiennutzer populations, aiming to reduce the digital divide.

Overall, the field of Laiennutzer research supports the creation of technology that is inclusive, safe, and adaptable, recognizing that most technology interactions occur in contexts where users possess only basic or incidental expertise.
