When Geolocation Gets Too Clever
Geo-redirecting -- redirecting users to different parts of your website depending on their own geographical location -- is a neat trick. It is handy when your website has different messages or product offers for users from different countries or regions. But many website owners mistakenly assume that their geolocation software works every time. It doesn't!

When Products Become Easy to Use, What's Next for Writers?
People who follow the right trends will someday lead them. Such an opportunity now lies in the hands of technical writers, as the computer field moves toward standardized, graphical, easy-to-use interfaces.

Why Consumer Products Have Inferior User Experience
Physical products, from consumer electronics to cars, are needlessly complex because they're developed by insular companies that continue to ignore the growing usability trend.

Zipf Curves and Website Popularity
Much available data suggests that Web use follows a Zipf distribution. The figure shows the distribution of incoming page requests to www.sun.com during a one-month period last year. Each datapoint represents one page, with the x-axis showing pages sorted according to popularity: the first page is the most popular one (the home page), the second page is the one that received second-most requests that month, and so on until we reach page number 10,000 which was only requested a single time that month.

我们常常看到这样的新闻报道：飞机坠毁夺走了好几百人的生命，某次工业事故导致几百万英镑的损失，某新发现的系统医疗错误致使数千病患重返医院。几个月后，公布的调查结果如下：操作机器设备时的人为错误导致了这些事故。人们使用‘人为错误’一词来表达‘操作上的错误’，而经常的情况是，这些‘人为错误’ 根本就是机器设备的人机界面设计或安装上本身固有的问题。低劣的人机界面会导致使用效率降低或者容易发生错误，严重的则会造成财产和生命损失。

你有没有怀疑过你的同事或者客户是否真的理解“可用性”？在我们和同事的在商务、技术和设计讨论中谈论‘可用性’是什么时，经常充斥着一些标准和指导方针替代品。在本文中，我们通过了解可用性的五个维度，我们便能够围绕可用性目标达成一致的看法，并开始以这个可用性的定义为基础，来计划用户中心设计的工作。

In my work with Bumblebee I use an approach I call 'User-Guide-Driven Development,' or UGDD for short. The mechanics of UGDD is similar to that of Test-Driven Development (TDD), but before I write the test for a feature, I write a snippet of the user guide describing the feature I am about to implement.

Switching Between Tools in Complex Applications 
Usability practice needs a procedure to identify, record, count, and highlight tool switch events for study. This paper describes one that supports the trained observers on which User-Centered Design relies to detect problems and causes, and evaluate design changes.

Usability Evaluation of a University Portal Website
This article provides a summary of a usability evaluation of a university portal website. University faculty, staff, and student users were asked to complete representative search tasks and provide feedback on the portal usability. Several user interface design issues were found to impact user performance in terms of task success and perceived task difficulty, in addition to overall satisfaction. From these results, recommendations are made for university portal design related to the default 'home' page, channel customization and configuration, and placement of user-specific functions.

Making Decisions About User Research
We know that we should do user research for projects. All the user-centred design material says so, we talk about it at conferences, we put it in proposals. We just know that it is a good thing to do. But when I talk to people about their actual projects, I find that very few people actually do user research. There are many many reasons (no time, no money, already know what users need etc etc etc). I think that part of the reason it doesn’t happen is also that we don’t have good tools to tell us just how much research to do, and even when it isn’t necessary at all to do research.

Why Users Can be Hard to Design For 
To know the mind of others is one of the fundamental problems of being human. Much of our energy is spent trying to do so. For web designers, knowing the mind of users is complicated by having very little interaction with them. It is possible, on some projects, to design and redesign web sites without ever talking to one user.

Designing for the "Average User"
User advocacy is one of the central goals of usability. User advocacy can be defined as the process an IT professional (with an interest in user experience) goes through in re-sensitizing herself to the world of the "average user."

Five Things to Know About Users
Over the years, we've studied the usability of hundreds of product and web site designs. We've seen designs that were incredibly effective for users and designs that fell tremendously short. One emerging pattern in our ongoing research is that design teams that know a lot about their users are more likely to produce user experiences that are usable, effective, and pleasing.

One of the most overlooked aspects of designing a Web site is how users get to it. Separate factions are often devoted to promoting, designing, and maintaining a Web site, and the lack of communication and involvement can lead to apathy or confusion. Too frequently is it assumed that visitors are knowledgeable about the company and Web site, and that they enter through the home page. False assumptions about visitor entry can plague even a well-planned, well-designed site.

Everyone is mad for personas. They’ve permeated the highest and deepest levels of organizations, and have become a standard interaction design tool. Whole projects are now built around creating them, and there’s a feeling that once you get a half dozen or so, your design problems will be solved. Presumably, your personas solve them for you. The problem is, most teams build personas from the wrong kind of user information, or worse, base them on assumptions. It’s no surprise that a Web search for personas brings up an amazing variety of persona sets, and most of them are terrible.

What is an End-User Software Engineer? 
To address the challenge of developing a shared understanding of the users that participate in each scenario we have developed a set of personas that describe the work styles, characteristics and motivations that are common to particular groups of people using our products. The personas help us communicate these characteristics by humanizing them, increasing the empathy that team members have for these fictional users.

Out of Box Experience: Getting it Right First Time
The out of box experience (OOBE) describes the users first interaction with a product or service. In the technology sector this first experience invariably involves plugging stuff in, installing some software and crossing your fingers in the hope that the product will work. The problem is that, in far too many cases, it doesn’t.

Usability Spotter #5: HP Laptop Touch Pads with Scroll Zones- Absence of Tactile Cue
Summary The issue with HP laptops that have a touch pad with a scroll zone contained it (as shown in image A) is that they do not provide a tactile cue for the user to help interpret what section of the touch pad the finger is positioned at. In the absence of a tactile cue, it is difficult for the user to determine whether the finger is on touch pad or the scroll zone without looking at it, resulting in the accidental scrolling on the screen when actually the user simply wants to move the cursor. The issue and multiple solutions are discussed ahead.

Documentation Usability: A Few Things I’ve Learned from Watching Users
Even though your customers may not read manuals, your tech support team probably does, which means someone is reading the manuals and using them to help others. But if your users find it easier to call someone, wait on hold for an agent, and then ask the agent a question rather than find the answer in the help, maybe your help materials aren’t very usable. Maybe increasing the usability of your company’s documentation could alleviate the need users feel to seek answers from another source.

This may sound a little harsh, but you'll see, when you do usability tests, that there are quite a few users who simply do not read words that you put on the screen. If you pop up an error box of any sort, they simply will not read it.

The Foundation of a Great User Experience
I’m part of the AEC User Experience Team at Autodesk. Our goal is to design a great user experience for our customers, but just what does that mean? Our definition of user experience focuses on all the touchpoints that current or new users have with our product. For example, the downloading of software trials is often the beginning of one’s user experience with a product. If you have to fill out forms that ask for too much information, (should “cell phone number” be a required field on a trial download form?) or present you with too many obstacles, the likelihood of a positive user experience will be low. Your interactions with technical support, documentation, the product, and even other products that you use, are all aspects of the user experience.
