Jakob Nielsen

Users experience the usability of a web site before they have committed to using it and before making any purchase decisions. The web is the ultimate environment for empowerment, and he or she who clicks the mouse decides everything. Designing Web Usability is the definitive guide to usability from Jakob Nielsen, the world's leading authority. Over 250,000 Internet professionals around the world have turned to this landmark book, in which Nielsen shares the full weight of his wisdom and experience. From content and page design to designing for ease of navigation and users with disabilities, he delivers complete direction on how to connect with any web user, in any situation. Nielsen has arrived at a series of principles that work in support of his findings: 1. That web users want to find what they're after quickly; 2. If they don't know what they're after, they nevertheless want to browse quickly and access information they come across in a logical manner. This book is a must-have for anyone who thinks seriously about the web.

Describes Web site usability through critiques of real-world sites, covering such factors as legibility, navigability, searchability, and design.

The book begins with a briefing on Jakob's web usability principles, themselves culled from years of research. The 50 sites fall under such categories as Fortune 500 Sites, Highest-Traffic Sites, and E-Commerce Sites.The content is simply presented: Four book pages are devoted to each homepage. The first page is a clean screenshot of the site's homepage (for readers to make their own, unbiased judgments), followed by a page that explains the site's purpose and summarizes its success--or failure--at usabilty. The third and fourth pages are devoted to crtiques, where Jakob and Marie present no-holds-barred commentary for specific usability practices, as well as suggestions for improvement. Although only the homepage of each site is analyzed, many of the critiques can be applied to overall website design.

Eyetracking Web Usability is based on one of the largest studies of eyetracking usability in existence. Best-selling author Jakob Nielsen and coauthor Kara Pernice used rigorous usability methodology and eyetracking technology to analyze 1.5 million instances where users look at Web sites to understand how the human eyes interact with design. Their findings will help designers, software developers, writers, editors, product managers, and advertisers understand what people see or don’t see, when they look, and why.With their comprehensive three-year study, the authors confirmed many known Web design conventions and the book provides additional insights on those standards. They also discovered important new user behaviors that are revealed here for the first time. Using compelling eye gaze plots and heat maps, Nielsen and Pernice guide the reader through hundreds of examples of eye movements, demonstrating why some designs work and others don’t. They also provide valuable advice for page layout, navigation menus, site elements, image selection, and advertising. This book is essential reading for anyone who is serious about doing business on the Web.

L'informatica è sempre più presente, nelle attività lavorative come nella vita quotidiana, mentre il tempo che si può dedicare allo studio e alla formazione è sempre più ridotto. I libri della serie Pocket Apogeo rispondono alla sfida: volumi da portare con sé, brevi corsi per imparare tutto quello che serve di un linguaggio, di un sistema operativo, di un programma applicativo o di un particolare campo delle tecnologie dell'informazione e della comunicazione. Volumi compatti, dunque, ma non a scapito della qualità: la brevità è ottenuta eliminando il superfluo ed escludendo l'inessenziale, puntando invece a quanto serve veramente per avere le idee chiare e sapersi orientare. In questo volume: "Web usabilità 2.0"

In the years since Jakob Nielsen's classic collection on interface consistency first appeared, much has changed, and much has stayed the same. On the one hand, there's been exponential growth in the opportunities for following or disregarding the principles of interface consistency-more computers, more applications, more users, and of course the vast expanse of the Web. On the other, there are the principles themselves, as persistent and as valuable as ever. In these contributed chapters, you'll find details on many methods for seeking and enforcing consistency, along with bottom-line analyses of its benefits and some warnings about its possible dangers. Most of what you'll learn applies equally to hardware and software development, and all of it holds real benefits for both your organization and your users.

Based on his best-selling HyperText and HpyerMedia, Jakob Nielsen takes hypertext a step further--to the Internet. Multimedia and The Internet and Beyond explores new and developing applications in multimedia and hypertext as well as offering coverage of the use of HTML (hypertext markup language) and the World Wide Web with interfaces such as Mosaic and Netscape.* Includes a large number of richly illustrated examples of a wide variety of new hypermedia systems.* Provides a range of strategies for overcoming information overload.* Thorougly discusses a number of new applications, including distribution of hypertext tools via the Internet.* Explains copyright issues for users and develeopers, and usability issues for hypertext.* Forecasts the future of the field in the long and short term.

Increasing technological sophistication in many countries and the resulting larger world trade has indicated a need to pay greater attention to the international aspects of user interfaces. Many American companies are approaching a situation where half of their sales are outside the United States, and companies in smaller countries often have a much larger proportion of their sales outside their own country. This means that software sales will increasingly depend on their international usability and not just their domestic usability. Seen from a user's perspective more than half of the world's software users will be using interfaces which were originally designed in a foreign country. Usability for this large market of users will depend upon increased awareness of the issues involved in designing user interfaces for international use. As the European community aims to establish the so-called Single Market by the end of 1992, international software will become even more important in that part of the world. And as if it wasn't hard enough to design user interfaces for use in Europe, there are a further set of problems connected with user interfaces for Asia. Both of these issues are examined in depth. This is the first publication of its kind to appear on the topic of international user interfaces, and presents both general guidelines and a number of detailed case studies on the many aspects entailed. The book will be of considerable interest to project managers, lecturers, students, developers of basic software and user interface designers.

You can’t sell a product that your customers can’t find. Your site must accommodate all types of searches and return relevant results for categories, products, and product characteristics. Search is a critical element of building a profitable website. In our recent e-commerce usability study, 83% of users searched on one or more sites.This 148-page report contains 62 design recommendations based on our usability research. Discussions and 130 screenshot illustrations supplement the findings.Even though some of the design guidelines are specific to searching for products, many of the guidelines apply to all forms of web searches, including general websites and intranets.Topics Exploiting search to meet customer needs Feeling for breadth or depth of the site's product selection Quickly locate a product category or something specific Fallback option to site navigation Narrow options Return to an item previously located Customer queries Search queries, what people type Query length Within site searches versus web-wide searches Best practices for search on e-commerce websites Placement of search Accommodating different lengths and types of searches Interpreting the query Narrowing options Returning useful results Advanced and scoped searches Presenting search results Sorting results Narrowing product choices Guided navigation versus faceted searchResearch MethodThe information in these reports is based on two separate rounds of e-commerce studies, including: One-on-one usability testing Diary-based longitudinal study EyetrackingRepresentative users tested 206 e-commerce websites. The studies took place in the United States, the United Kingdom, Denmark, and China (Hong Kong).

Die Informationstechnologie im Zeitalter nach Gutenberg bedeutet neue Herausforderungen für Autoren, Journalisten und Medienschaffende jeglicher Provenienz.
