Most abstract information spaces work poorly in 3D because they are non-physical. If anything, they have at least a hundred dimensions, so visualizing an information space in 3D means throwing away 97 dimensions instead of 98: hardly a big enough improvement to justify the added interface complexity.

大きい画面の利点についてのテストには、2 つの間違いがあった。現実的なタスクでテストしていなかったことと、現実的な利用方法でテストしていなかったことだ。生産性は、労働環境のユーザビリティを語る上で重要な項目になるが、それを計測する場合は、注意深く行わなければいけない。

"About Us" -- Presenting Information About an Organization on Its Website
Study participants searched websites for background information ranging from company history to management biographies and contact details. Their success rate was 70%, leaving much room for usability improvements in the 'About Us' designs.

A strict focus on accessibility as a scorecard item doesn't help users with disabilities. To help these users accomplish critical tasks, you must adopt a usability perspective.

Accessible Design for Users With Disabilities
Making the Web more accessible for users with various disabilities is to a great extent a matter of using HTML the way it was intended: to encode meaning rather than appearance. As long as a page is coded for meaning, it is possible for alternative browsers to present that meaning in ways that are optimized for the abilities of individual users and thus facilitate the use of the Web by disabled users.

Alternative Interfaces for Accessibility
The key difference between user interfaces for sighted users and blind users is not that between graphics and text; it's the difference between 2-D and 1-D. Optimal usability for users with disabilities requires new approaches and new user interfaces.

Amazon: No Longer the Role Model for E-Commerce Design
Many design elements work for Amazon.com mainly because of its status as the world's largest and most established e-commerce site. Normal sites should not copy Amazon's design.

The Anti-Mac: Violating the Macintosh Human Interface Guidelines
Graphical computer interfaces have become the norm. They are based on a number of principles such as metaphor, see-and-point, direct manipulation, user control, and WYSIWIG. The Anti-Mac project explored alternative interfaces that might result from violating the principles behind conventional graphical interfaces. What emerges is a human-computer interface based on language, a richer representation of objects, expert users, skilled agents, and shared control.

Most usability practitioners don't derive full value from their user tests because they don't systematically archive the reports. An intranet-based usability archive offers four substantial benefits.

Opponents of the usability movement claim that it focuses on 'stupid' users and that most users can easily overcome complexity. In reality, even smart users prefer pursuing their own goals to navigating idiosyncratic designs. As Web use grows, the price of ignoring usability will only increase.

Authentic Behavior in User Testing
Despite being an artificial situation, user testing generates realistic findings because people engage strongly with the tasks and suspend their disbelief.

Automated Email From Websites to Customers
Transactional email can be a website's customer service ambassador, but messages must first survive a ruthless selection process in the user's in-box. Differentiating your message from spam is thus the first duty of email design.

On the Web, users have a clear mental model for a hypertext link: it should bring up a new page. Within-page links violate this model and thus cause confusion.

Avoiding Bias from the Survivor Effect
Only a few of the survey sites we analyzed in 2000 are still around. We can safely assume that the surviving sites are not a random sample of the original group, but rather that significant differences exist between the sites that made it and those that died. Survival might be due partly to luck, but it is mainly a result of good management and an understanding of Internet fundamentals. Thus, the surviving sites are likely to be disproportionately clued-in about what it takes to run an online business.

Banner Blindness: Old and New Findings

Bass Curves for the Diffusion of Innovations
Uptake of hypertext is likely to happen somewhat differently than the standard Bass curve. First, the market for hypertext use is highly dependent on the number of people who have computers with certain minimum capabilities (typically at least a graphical user interface; for WWW use it is also necessary to have Internet access). Second, the influence of other hypertext users is almost certainly not linear.

Be Succinct! (Writing for the Web)
The three main guidelines for writing for the Web are: be succinct: write no more than 50% of the text you would have used in a hardcopy publication; write for scannability: don't require users to read long continuous blocks of text; use hypertext to split up long information into multiple pages.
