Jakob Nielsen, a cofounder of the Nielsen
Norman Group, is a consultant on the usability of
the World Wide Web and holds a PhD. in human-
computer interaction. He studies user interactions
and proposes quick and easy ways to implement
software functions that increase user productivity.
Early in his career, Dr. Nielsen worked mostly on
large-scale software applications. However, while
at Sun Microsystems in the 1990s, he switched
to studying the usability of what was then the
emerging technology of the World Wide Web. While
his focus has been on the Internet, his advice to
keep common actions performed in the same way
is a key concept in the design of user interfaces.
Dr. Nielsen has published many books and articles.
His 1989 text Coordinating User Interfaces for
Consistency is considered a standard in how to y
design a consistent look and feel for software. It is
still in demand and frequently cited.
