Nielsen's affiliations include
Bellcore, teaching at the
Technical University of Denmark, and the
IBM User Interface Institute at the
Thomas J. Watson Research Center. From 1994 to 1998, he was a distinguished engineer
Sun Microsystems.
Website usability writing Beginning in 1996, Nielsen published a
fortnightly column about
website usability called Alertbox on his now-archived personal website useit.com. Alertbox was syndicated to, and eventually replaced by, the weblog and email newsletter on the Nielsen Norman Group website during the 2000s. Nielsen has published several books on the subject of
web design. Nielsen founded UX Tigers in 2023 where he currently publishes articles on the topics of usability, with a heavy focus on the intersection of digital usability and artificial intelligence, and publishes video content about usability.
Nielsen Norman Group (NNG) After his regular articles on his website about usability research attracted media attention, he co-founded usability consulting company
Nielsen Norman Group (NN/g) of
Fremont, California in 1998 with fellow usability expert
Donald Norman. The company's vision is to help designers and other companies move toward more human-centered products and internet interactions, as experts and pioneers in the field of
usability. mainly on ways of improving usability for technology. In the early 1990s, Nielsen popularized the principle that five test users per
usability test session is enough, allowing numerous tests at various stages of the development process.
Jakob's law Users will anticipate what an experience will be like, based on their
mental models of prior experiences on websites. When making changes to a design of a website, try to minimize changes in order to maintain an ease of use. Nielsen published an updated set in 1994, and the final set still in use today was published in 2005: • Visibility of system status • Match between system and the real world • User control and freedom • Consistency and standards • Error prevention • Recognition rather than recall • Flexibility and efficiency of use • Aesthetic and minimalist design • Help users recognize, diagnose, and recover from errors • Help and documentation In his book
Usability Engineering (1993), Nielsen also defined the five quality components of his "Usability Goals": • Learnability • Efficiency • Memorability • Errors (as in low error rate) • Satisfaction
Windows 8 usability Nielsen has been quoted in the computing and the mainstream press for his criticism of
Microsoft's Windows 8 (2012) user interface. Tom Hobbs, creative director of the design firm
Teague, criticized what he perceived to be some of Nielsen's points on the matter, and Nielsen responded with some clarifications. The subsequent short and troubled history of Windows 8, released on 26 October 2012, seems to have confirmed Nielsen's criticism: the sales of Windows-based systems plummeted after the introduction of Windows 8; Microsoft released a new version, Windows 8.1, on 18 October 2013, to fix the numerous problems identified in Windows 8, and later released
Windows 10, a complete overhaul, in July 2015.
Criticisms As Nielsen's newsletter and website grew, and with his use of "
acronomic platitudes" to describe his concepts, some critics like
Philip Greenspun argued that Nielsen's work was more about marketing himself than any particular research. There has never been any research-based validation of Nielsen's heuristics. Nielsen has been criticized by some
visual designers and
graphic designers for failing to balance the importance of other
user experience considerations such as typography, readability, visual cues for hierarchy and importance, and eye appeal.
Responsive design Nielsen's 2012 guidelines, "
Repurposing vs Optimized Design" that web sites made for mobile devices be designed separately from their desktop-oriented counterparts has come under fire from
Webmonkey's Scott Gilbertson, as well as Josh Clark writing in
.net magazine, and
Opera's Bruce Lawson, writing in
Smashing Magazine, and other technologists and web designers who advocate
responsive web design. In an interview with
.net magazine, Nielsen explained that he wrote his guidelines from a usability perspective, not from the viewpoint of implementation. Nielsen has been accused of taking a "
puritanical" approach to usability, and not being able to keep up his usability evaluations in step of technological changes. In recognition of Nielsen's contributions to usability studies, in 2013
SIGCHI awarded him the Lifetime Practice Award. ==References==
