326. #27107 Helping Your Visitors: A State of Mind Remember your site visitors won't find your website as easy to use as you do. Change your state of mind and you'll improve the user experience for all visitors. Usborne, Nick. Webcredible (2006). Design>Web Design>User Centered Design>Usability 327. #14881 Heuristic Evaluations vs. Usability Testing How many of the usability problems identified in a heuristic evaluation are true usability problems? Several years ago, I published an article suggesting that many of the 'problems' identified by heuristic evaluators were not problems at all (Bailey, Allan and Raiello, 1992). Even so, many of us have continued to waste time and go to the expense of fixing many usability problems that were not problems. Recently, three research papers were published that provided some insights into the validity of heuristic evaluations (Catani and Biers, 1998; Rooden, et.al., 1999; Stanton and Stevenage, 1998). The articles discussed usability testing in three totally different domains with very similar results. Bailey, Robert. Human Factors International (2002). Articles>Usability>Web Design 328. #27487 At a time when the customer service culture has penetrated every level of business, and businesspeople fret endlessly over issues such as customer loyalty, companies are extremely susceptible to worries that they are, without even knowing it, turning customers away. Eliot, Ben. Spiked Online (2002). Articles>Web Design>Usability 329. #27476 Research indicates that most users never find the majority of the functionality in any given application. Learning tends to reach a plateau early on, and is rarely expanded upon. And what that means is that most customers consistently undervalue the software products they purchase and use. Farrell, Tom. Frontend Infocentre (2006). Design>Web Design>Usability>User Centered Design 330. #25098 Home Stayers And Trench Diggers This paper offers some observations on the ways 9 to 12 year children search for information on websites and how this may differ from the search behaviour of adults. Hudson, Roger. Usability.com.au (2002). Articles>Web Design>Usability>Search 331. #18455 Homepage Real Estate Allocation On average, sample sites evenly distributed valuable screen space between content, navigation, fluff, blank areas, and system overhead. Areas of user interest should occupy more than the current 39%. Nielsen, Jakob. Alertbox (2003). Design>Web Design>Usability 332. #21766 How Big is the Difference Between Websites? The average difference in measured usability between competing websites is 68%. This is smaller than expected, but makes sense given the dynamics of design within individual industries. Nielsen, Jakob. Alertbox (2004). Articles>Usability>Web Design 333. #27387 Discusses how Anthem attained the training, standards, and resources they needed to create a sustained usability effort.

Seiden, Alan. Usability Professionals Association (2005). Articles>Web Design>Usability>E Commerce 335. #19428 How Good are Designers at Predicting User Performance? Having designers guess the best way of achieving optimal user performance is very difficult. Their design decisions can be improved by ensuring that designers are familiar with the research literature, and by effectively using performance-based usability testing. Bailey, Robert. Web Usability (2001). Design>Web Design>User Centered Design>Usability 336. #23058 How Good Does Your Web Site Look on Paper? Paper prototyping is a fast, low-cost method of testing web site designs. It involves creating rough sketches of a web site design and inviting some of your users to take the design for a test drive using their pen, instead of a mouse, to complete important tasks. Janisch, Troy. Icon Interactive (2004). Articles>Web Design>Usability 337. #13343 How Important is Visual Feedback When Using a Touch Screen? From check station point-of-sale devices (restaurants, grocery stores, etc.) to information kiosks, to the cars we drive (navigation systems), touch screens have become the input device of choice. While the versatility of the touch screen is highly desired, the poor performance it achieves relative to the mechanical keyboard has been something that users have been forced to deal with. Empirical research studies have found that touch screens consistently produced slower and less accurate performance when compared with keyboards (Barrett & Krueger, 1994; Wilson, Inderrieden, & Liu, 1995). Schneiderman (1998) outlines the many advantages and disadvantages to using a touch screen. Deron, Michael. Usability News (2000). Articles>Usability>Design 338. #19435 How Long Should Users Have to Wait? In a well-designed website, how long should users have to wait for pages to download? Bailey, Robert. Web Usability (2001). Design>Web Design>Usability 339. #10142 Bradley Dilger writes that making computers 'easy' may also make them less useful. 'Ease is never free: its gain is matched by a loss in choice, security, privacy, health, or a combination thereof,' he says. He urges professors to understand the inimical effects of ease and explore pedagogical practices that can counter those effects. Dilger, Bradley. Journal of Electronic Publishing (2000). Design>Usability>Technology 340. #22110 How Not to Make Your Site Accessible Web sites are designed by people with fast, powerful computers, modern browsers, IT staff to keep verything running, their choice of software, and local disk storage -- or at worst, a fast network. They are browsed by people with any of a variety of computers, whatever browser the machine shipped with, software that may have been installed by an IT department that thinks Web browsing is counterproductive, and modems. In fact, it's so easy to ignore this gap that it's easier to offer advice for how to flaunt it than it is to give advice for closing it. Following is a set of principles for doing just that -- making your site as inaccessible as possible. Seebach, Peter. IBM (2001).

Design>Documentation>Information Design>Usability 342. #27406 How to Avoid Being Blinded By Your Own Design: Seeing the Forest for the Trees If you design something for your company, organization or department, or help influence the direction of a design, it regularly can become very difficult for you to separate yourself from the design. And chances are, you are not even aware of it most of the time! This entry looks at why this seems to happen and what you can do about it (if anything at all). Spillers, Frank.

Get the lowdown on how to achieve this within your organisation. Ismail, Ismail. Webcredible (2007). Articles>Usability>User Centered Design 344. #26548 How to Improve Your Site Search (...or ‘looking for jamie oliver’) Site search engines should always allow for common user errors. By taking these errors into account, users should be able to always find what they're looking for through the site search. Fidgeon, Tim. Webcredible (2005). Design>Web Design>Usability>Search 345. #21048 How to Make URLs User-Friendly One of the worst elements of the web from a user interface standpoint is the URL. However, if they're short, logical, and self-correcting, URLs can be acceptably usable. Baker, Adam. Merges.net (2001). Design>Web Design>User Centered Design>Usability 346. #20233 Dynamic websites are great. Dynamically-generated URLs stink. In Part One of a new series, Till Quack shows how to use PHP to convert machine-generated URLs into human-friendly ones. Quack, Till. List Apart, A (2001). Design>Web Design>Usability 347. #18398 Human Error and the Design of Computer Systems People err. That is a fact of life. People are not precision machinery designed for accuracy. In fact, we humans are a different kind of device entirely. Creativity, adaptability, and flexibility are our strengths. Continual alertness and precision in action or memory are our weaknesses. We are amazingly error tolerant, even when physically damaged. We are extremely flexible, robust, and creative, superb at finding explanations and meanings from partial and noisy evidence. The same properties that lead to such robustness and creativity also produce errors. The natural tendency to interpret partial information -- although often our prime virtue -- can cause operators to misinterpret system behavior in such a plausible way that the misinterpretation can be difficult to discover. Norman, Donald A. JND.org (1999). Design>Human Computer Interaction>Usability 348. #25074 The phrase 'human error' is taken to mean 'operator error', but more often than not the disaster is inherent in the design or installation of the human interface. Bad interfaces are slow or error prone to use. Bad interfaces cost money and cost lives. Dix, Alan. uiGarden (2005). Articles>Human Computer Interaction>Usability>User Centered Design 349. #19179 Human-Computer Interaction for Kids How is designing computer software and hardware for kids different from designing for adults? At the time of this writing, little formal research has been done on this topic. Most research done to date has focused on designing educational software, and evaluation is primarily of learning outcomes, not usability. However, usability is a prerequisite for learning.
