There is no doubt that, in pro-disabled accessibility discourse, certain groups are privileged above others. Whilst there is increasing sensitivity to this in Computer Science, with developers and researchers working to close the distance, this reasons for this divide are under-theorised within ICT discourse.
How shall we design accessible GUIs? Which are the main problems, which are the right paths and techniques for doing this? The article is a story about an experience, about the development of an accessible GUI and an analyses of the procedures.

I will examine this unfortunate side effect, Repetitive Strain Injury (RSI), of the Digital Age in this essay. It has probably affected someone you know. I hope this information will cause you to pause, look at your computer setup and initiate changes that make your computing safer and more comfortable. And if you've already experienced some of RSI's disabling and career-threatening effects, I hope that this article eases some of your anxieties by describing methods, approaches and treatments that have helped others.
Interview with John Carroll, best‑known among technical communicators as “The Father of Minimalism,” a title he earned as a result of his popular book, The Nurnberg Funnel.
The development of 3D animation systems has been driven primarily by a hyper-realist ethos, and 3D computer graphic (CG) features have broadly complied with this agenda. As a counterpoint to this trend, some researchers, technologists and animation artists have explored the possibility of creating more expressive narrative output from 3D animation environments. This article explores 3D animation aesthetics, technology and culture in this context.
An artifact simply means any product of human workmanship or any object modified by man. It is used to denote anything from a hammer to a computer system, but it is often used in the meaning 'a tool' in HCI or Interaction Design terminology. The term is also used to denote activities in a design process.
Writers and editors in particular put in an awful lot of miles at the keyboard every day. One serious problem is the risk of so-called 'repetitive-stress injury' (RSI)--simplistically, any injury that results from overuse of a body part without giving it time to recover. In fact, 'overuse injury' is probably a more immediately obvious term, and given how much time many of us spend using computers, overuse is indeed a risk.
Writers and editors in particular put in an awful lot of miles at the keyboard every day. For example, I commonly spend a solid 8 hours typing. Writers and editors in particular put in an awful lot of miles at the keyboard every day. For example, I commonly spend a solid 8 hours typing. Then there's that darned mouse. W. Wayt Gibbs, writing in the June 2002 Scientific American, used the Mouse Odometer software (www.modometer.com) to monitor his habits and found that in a single 5-day period, he'd recorded 2440 feet of mouse movement and nearly 22 000 mouse clicks. It's no wonder computer users sometimes experience serious physical problems.It's no wonder computer users sometimes experience serious physical problems.
What if something neither looks nor quacks like a duck, but users think it is a duck? The cranky user comments on baby duck syndrome and how it can trap users with systems and interfaces that don't really meet their needs.
Making thoughts, ideas and plans explicit by writing them down or by developing an artifact, we create situations which talk back to us. For example, architects use the backtalk of their work extensively. When sketching, unexpecting patterns emerge, which are incorporated and maybe elaborated on in the drawing. Thus, the act of sketching is not only the conscious act of sketching the intended subject, but an interplay between the sketcher, the materials and possibly other situational constraints.
Abgeflachte Bürgersteige, Rampen statt Stufen, tiefergelegte Busse - an den alltäglichen baulichen Barrieren für Kinderwägen und Rollstuhlfahrer wird gearbeitet. Im IT-Bereich dagegen ließ Barrierefreiheit bislang auf sich warten: Viele Websites sind nicht für jeden zugänglich. Mit dem Gesetz zur Gleichstellung behinderter Menschen sind öffentliche Institutionen seit Anfang Mai 2002 verpflichtet, ihre Websites barrierefrei zu gestalten.
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.
We humans are biological animals. We have evolved over millions of years to function well in the environment, to survive. We are analog devices following biological modes of operation. We are compliant, flexible, tolerant. Yet we people have constructed a world of machines that requires us to be rigid, fixed, intolerant. We have devised a technology that requires considerable care and attention, that demands it be treated on its own terms, not on ours. We live in a technology-centered world where the technology is not appropriate for people. No wonder we have such difficulties.
As a growing and integral part of America's corporate workforce, technical writers increasingly share general employee benefits and burdens. Negative trends that affect the workforce in many companies now threaten serious damage to the teams that technical writers work on, the projects they develop, and ultimately the revenues that pay their salaries. The structural and secondary effects of such trends are explained; an illustration is given in the case of one company; and predictions are made about where such trends will lead.
Given the choice, how many people would swap a gloriously sunny Saturday in Cambridge, England, for a 7-hour long tutorial about—wait for it—qualitative user research and analysis methods? Yet thirty odd people did just that, electing to closet themselves in one of the nicer rooms at Churchill College to listen to what UCD researcher David Siegel had to say. This tutorial turned out to be a highly motivating, fast-paced, and anecdote-rich journey through the process of designing and analyzing qualitative field work in a user-centered design (UCD) context.
This study investigates the breakdown of the psychomotor components of three different input devices, the mouse, trackball, and RollerMouse™ using the Stochastic Optimized Submovement Model. Primary movement time (PMT), Total Movement Time (TMT), Primary Movement Distance (PMD), and Total Movement Distance (TMD) were examined for each device. Results showed that psychomotor variables related to the primary phase of movement help to pinpoint how performance efficiency is affected by a particular device. For example, the relationship between %PMD and efficiency suggests that a device that affords users an initial accurate movement decreases the need for more or longer corrective submovements, thus reducing movement time.
Have you ever been working at the computer so long that your eyes 'went buggy?' Or so intensely that you could barely move when you got up? Working long hours at a computer may be more hazardous than you know. One real possibility is that you will develop Carpal Tunnel Syndrome (CTS).
When writing software, *please* don't give error messages that are only meaningful to developers of the software. Microsoft used to be awful for this: "System fault at DEAD:BEEF, please contact your system administrator". Which would've been cool, except that I *was* the system administrator.
Mobile phones become part of the most intimate and personal space with its users unlike any other computer devices or software applications. Mobile phones accompany the individuals almost everywhere be it home, office, public places or even the most private locations. It connects us with the worlds beyond our physical reach as well as the worlds within our vicinity. The need for culture-friendly mobile interfaces and applications is felt when we are interacting with the worlds within our vicinity (local culture) or when the user interacts with another culture. Considering the intimate relation of mobile phones with its users, the quality of “culture-friendliness” becomes very critical for a successful interaction within the personal as well as social space.
The file system has been a trusted part of most computers for many years, and will likely continue as such in operating systems for many more. However, several emerging trends in user interfaces indicate that the basic file-system model is inadequate to fully satisfy the needs of new users, despite the flexibility of the underlying code and data structures.
The purpose of this research is to investigate the usability of DVD interfaces via their menus and navigation, inspired by Donald Norman who has had a pivotal role in user-centred design and usability. The paper encompasses theoretical aspects of interactivity, usability and DVD technology. A usability test was administered with the DVDs chosen. The results from the usability test were the main focus in this research. Such results were supportive of Norman's claims, as participants experienced varying degrees of usability issues. Furthermore, the findings were used to develop a set of guidelines and recommendations designers could follow. If these were adhered to, it would have significantly alleviated the difficulty the participants had in interacting with the DVDs.
The IL-HUMASS survey on information literacy has been designed, based on and aimed to be applied to a population of students, teachers and librarians holding various degrees in social sciences and humanities at Spanish and Portuguese universities. The case-study method, experts’ opinions, and a literature review were used to prepare an initial version that was refined through student focus groups, interviews with librarians, and academics’ reports. A final version contained 26 items grouped into four categories (information search, assessment, processing and communication/dissemination) and three self-reporting dimensions (motivation, self-efficacy and favourite source of learning). The self-reporting nature of the IL-HUMASS survey involves a self-assessment approach that has until now been proposed rarely and only in a limited way. This will enable a better understanding of user groups through a mixed analysis including two quantitative dimensions (motivation and self-efficacy) and one qualitative dimension (the preferred source of learning).
