Jakob Nielsen - Jakob Nielsen Jakob Nielsen (Born 1957 in Copenhagen, Denmark) is a writer, speaker, and consultant on software and web-design usability. He earned a Ph.D. in user interface design and computer science from the Technical University of Denmark. Nielsen worked at Bellcore, IBM, and as a senior researcher at computer company Sun Microsystems. He subsequently co-founded usability consulting company Nielsen Norman Group with fellow usability expert Donald Norman. He is noted for his (often stern) criticisms of popular websites, pointing out how he feels many concentrate too heavily on gimmicky features such as animation, flash, and graphics at the expense of usability, particularly for disabled visitors. Nielsen writes a monthly newsletter on web design matters and has published several books on the subject of web design. His.
Information foraging - the expected outcome. When the information scent stops getting stronger (i.e. when users stop finding useful additional information and don't expect to find it soon), people move to a different information source. Some tendencies in users' behaviour are easily understood from the information foraging theory standpoint. On the Web, each site is a patch and information is the prey. Leaving a site has always been easy, but finding a good one was not. Google has changed this fact by reliably providing relevant links and altered the searching strategies of the users. When users expect that sites with lots of information are easy to find, they have less incentive to stay in one place. The growth of broadband connections had a similar effect. With dial-up, connecting to Internet was difficult and users.
Heuristic evaluation - with recognized usability principles (the "heuristics"). The main goal of heuristic evaluations is to identify any problems associated with the design of user interfaces. Jakob Nielsen developed this method on the basis of several years of experience with teaching and consulting about usability engineering. Heuristic evaluations are one of the most informal method of usability inspection in the field of Human-computer interaction. A small group of evaluators examine a user interface and determine whether the interface conforms to established usability principles, called heuristics. There are many sets of usability design heuristics, they are not mutually exclusive and cover many of the same aspects of interface design. Quite often, usability problems that are discovered are categorized according to their estimated impact on user performance or acceptance. Often the heuristic evaluation is conducted.
Usability testing - aim is to observe users function in a realistic setting, performing realistic tasks, so that developers can see where they face problems, and what they like. The technique popularly used to gather data during a usability test is called a talk aloud protocol. What to Measure. Usability testing generally involves measuring how well test subjects respond in four areas: time on task, accuracy, recall, and emotional response. The results of the first test are the baseline or control measurement; all subsequent tests are compared to the baseline. Time on Task -- How long does it take users to complete a set of basic tasks? (For example, find something you want to buy, create a new user account, and order the item.) Accuracy -- How many mistakes did users make? (Can the.
Usability engineering - to the field of human-computer interaction and industrial design. See also usability, usability testing. Among the leading proponents of this field of study are Donald Norman and Jakob Nielsen. Nielsen has written a book on the subject, aptly titled Usability Engineering, which was published in 1994. The subject is considered of sufficient importance that a number of universities include a usability engineering course as part of the computer science curriculum..

Anti-Mac - of the Apple Macintosh graphical user interface. The term comes from an essay by Don Gentner and Jakob Nielsen. Gentner and Nielsen argue that the standard interface for personal computers was conceived when most users had no experience with computing, and the computers themselves were limited, stand-alone devices. Now, an entire generation has been raised with computers, and the PC has evolved into a powerful, connected device. The old WIMP (Windows, Icons, Menu, Pointer) interface has not changed to keep up with users or technology, sticking with clumsy metaphors like the desktop. Proposed solutions include a command line interface that can understand simple instructions, more metadata on files and objects, etc..
