For example, a quick examination of the Firefox 3.0 browser, shown in Figure 1 in its standard configuration, yields eight examples of arrows—Forward, Back, and Reload buttons, scroll bar controls, and drop-down menus that reveal search engine, history, and bookmark choices. http://tc.eserver.org/35574.html http://tc.eserver.org/35574.html Touchscreen devices can only work well if both hardware and software are uniquely optimized for touch interaction. Simply adding touch interaction to an existing device will make the user experience worse instead of better. http://tc.eserver.org/35487.html http://tc.eserver.org/35487.html It's not uncommon to hear people complaining about the poor user experience of some B2B and enterprise applications. Read through these top tips to help you design enterprise applications that offer a better user experience and increase productivity. http://tc.eserver.org/35493.html http://tc.eserver.org/35493.html 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. http://tc.eserver.org/35498.html http://tc.eserver.org/35498.html The future of how we interact with computers is exciting to say the least. What once seemed like nonsense outside of Hollywood and Science Fiction is now starting to find it’s way into reality, and some of the technology is a bit overwhelming. Have a taste of what the future of interface design has to offer: http://tc.eserver.org/35291.html http://tc.eserver.org/35291.html The issue of accidentally activating the browser back button through the keyboard while interacting with a long web form is applicable to users across expertise levels. The time and effort wasted by the user can be said as proportional to the number of input fields filled by the user before accidentally exiting the page. Since no application feedback indicating cause of the error to the user is provided, depending upon user expertise, the user may or may not realize the cause of the error. Realizing what went wrong does not guarantee the possibility of reverting the error either. This leads to unnecessary loss in form conversions despite favorable user intent. A solution to resolve this issue (that the author hopes becomes standard practice) to plug the hole for lost conversion that translates to big numbers in absolute terms for high traffic websites is also provided. http://tc.eserver.org/34879.html http://tc.eserver.org/34879.html 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. http://tc.eserver.org/34471.html http://tc.eserver.org/34471.html Human-computer interaction (HCI) is an area of research and practice that emerged in the early 1980s, initially as a specialty area in computer science. HCI has expanded rapidly and steadily for three decades, attracting professionals from many other disciplines and incorporating diverse concepts and approaches. To a considerable extent, HCI now aggregates a collection of semi-distinct fields of research and practice in human-centered informatics. However, the continuing synthesis of disparate conceptions and approaches to science and practice in HCI has produced a dramatic example of how different epistemologies and paradigms can be reconciled and integrated. http://tc.eserver.org/34439.html http://tc.eserver.org/34439.html 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. http://tc.eserver.org/33571.html http://tc.eserver.org/33571.html Photo albums from previous presentations of Games To Explain Human Factors. http://tc.eserver.org/33467.html http://tc.eserver.org/33467.html Computer glitches would be a lot less annoying if the machines were programmed to acknowledge errors gracefully when something goes wrong, instead of merely flashing up a brusque "you goofed" message. http://tc.eserver.org/33469.html http://tc.eserver.org/33469.html The popularity of touch input devices for use in a wide variety of information, telecommunication, and other systems applications warrants a review of the role of human factors in the design and use of these devices, particularly touch screens and touch pads. This report reviews empirical research into the human interface design issues of touch input devices including display mounting angle, touch biases, touch area size and shape, feedback, and touch key interaction strategies. The limitations and capabilities of the devices for supporting a variety of tasks are examined as are comparisons between these devices and more conventional input devices such as keyboards. Attempts to improve the user interaction with these devices are also reviewed. Conclusions and recommendations regarding the use and design of touch input devices are provided. http://tc.eserver.org/33434.html http://tc.eserver.org/33434.html My most recent captology course at Stanford focused on 10 ways computers manipulate people. In total, I've found about 60 strategies that software can use to change what people think and do. http://tc.eserver.org/33438.html http://tc.eserver.org/33438.html Our lab has been investigating how computer-based narratives can change people's beliefs and behaviors. http://tc.eserver.org/33439.html http://tc.eserver.org/33439.html Computer technology opens new doors for researching, creating, and distributing WIN (interactivity and narrative) experiences. Increased insight in this area could create a potential to change people’s attitudes and behaviors in ways never before possible. For example, in researching WIN experiences, our online system can now test stories to identify which stories have an impact on specific types of people. Alternately in creating WIN experiences, a computer could glean information from an interaction in order to select a specific story from a large database of proven stories. From a distribution standpoint, WIN experiences could be delivered through mobile handsets, increasing reach beyond the desktop. The potential for impact is significant. Computer-supported WIN experiences could lead to large-scale interventions to improve health, enhance learning and training, boost workplace performance, and motivate participation in civic life. http://tc.eserver.org/33353.html http://tc.eserver.org/33353.html It is easy to be complacent about the future in this climate and to forget the lessons of the dotcom crash of a few years ago. At that time, usability professionals struggled in a market that was dominated by cost-cutting. The problem then was that usability had a limited business offering that focused on optimisation. http://tc.eserver.org/33293.html http://tc.eserver.org/33293.html Are touchscreens always good news for users? Our consultants suggest guidelines to ensure touchscreen devices are both usable and useful. http://tc.eserver.org/33294.html http://tc.eserver.org/33294.html An ever increasing range of mobile phones are appearing on the market, each with their own features, designs and interfaces. Our extensive experience of working with a wide range of phones suggests that, despite their many differences, there are some user interface requirements common to all mobile phones. These requirements are presented as guidelines below. http://tc.eserver.org/33300.html http://tc.eserver.org/33300.html In this paper we critically review task analysis models and techniques. These approaches to task analysis are discussed in order to develop a richer picture of human activity, while analyzing their limitations, general weaknesses, and possibilities for improvement. We consider their ability to determine the appropriate set of atomic actions in a task, their effect on workers’ motivational needs, their support of users’ cognitive and sociocultural processes, and their effectiveness in supporting interface design. We note that the major approaches have focused on very different levels of analysis, and call for greater integration of these different levels in task analysis theory. http://tc.eserver.org/33245.html http://tc.eserver.org/33245.html Videotape has become one of the CHI community's mostuseful technologies: it allows us to analyze users' interactions with computers,prototype new interfaces, and present the results of our research andtechnical innovations to others. But video is a double-edged sword. It isoften misused, however unintentionally. How can we use it well, without compromising our integrity? This paper presents actual examples of questionable videotaping practices. Next, it explains why we cannot simply borrow ethical guidelines from otherprofessions. It concludes with a proposal for developing usable ethical guidelines for the capture, analysis andpresentation of video. http://tc.eserver.org/33193.html http://tc.eserver.org/33193.html the European Thematic Network for the human-centered design of interactive technologies. Convivio supports and promotes the development of "convivial technologies", ICT products, systems and services that enhance the quality of everyday life and human interaction. http://tc.eserver.org/33210.html http://tc.eserver.org/33210.html Evaluation is a fundamental part of human-computer interaction (HCI). Good HCI practice tells designers to evaluate: evaluate requirements, evaluate designs, evaluate prototypes. The purpose of evaluation is to improve the usability of a software system; that is to make it easy to use, easy to learn, effective and enjoyable. But what is usability and what makes one device easier to use than another? Traditional HCI theory has produced a number of evaluation techniques and guidelines. These are based on some basic psychological assumptions which date back to the sixties. http://tc.eserver.org/33042.html http://tc.eserver.org/33042.html 很多人难以理解我的那篇“以人为中心的设计是有害的”文章。 （哈哈，下面这样说可能有些保守！关于这个问题，肯定有五百篇评论和博客文章。） 特别地，我没能够清楚地说明“以活动为中心的设计”是什么意思，以及它和“以人为中心的设计”是如何的不同。 一些人好像认为我彻底抛弃了我以前说过的话。另外一些人则简单地认为我疯了。还有一些人则急匆匆地出来解释我那样说的含义。 http://tc.eserver.org/32974.html http://tc.eserver.org/32974.html Although ethnography has become a common approach in HCI research and design, considerable confusion still attends both ethnographic practice and the metrics by which it should be evaluated in HCI. Often, ethnography is seen as an approach to field investigation that can generate requirements for systems development; by that token, the major evaluative criterion for an ethnographic studies is the implications it can provide for design. Exploring the nature of ethnographic inquiry, this paper suggests that “implications for design” may not be the best metric for evaluation and may, indeed, fail to capture the value of ethnographic investigations. http://tc.eserver.org/33008.html http://tc.eserver.org/33008.html Human-Centered Design has become such a dominant theme in design that it is now accepted by interface and application designers automatically, without thought, let alone criticism. That’s a dangerous state – when things are treated as accepted wisdom. The purpose of this essay is to provoke thought, discussion, and reconsideration of some of the fundamental principles of Human-Centered Design. These principles, I suggest, can be helpful, misleading, or wrong. At times, they might even be harmful. Activity-Centered Design is superior. http://tc.eserver.org/33009.html http://tc.eserver.org/33009.html 在设计界，以人为中心的设计已经成为一个占统治地位的主题，以至于它经常被界面和应用设计人员不加思考地加以采用，更不要说是用一种带有批判的眼光加以采用。这是一种危险的状态――当某些事情被当作是被广泛认可的知识来对待时。这篇文章的目的就是要引起人们对于以人为中心设计方法的基本原理的重新思考和讨论。我认为，这些原理可能是有益的，有误导性的，或是是错误的。有时候，它们甚至可能是有害的。以活动为中心的设计是更好的一种方法。 http://tc.eserver.org/33010.html http://tc.eserver.org/33010.html HCD has developed as a limited view of design. Instead of looking at a person’s entire activity, it has primarily focused upon page-by-page analysis, screen-by-screen. As a result, sequences, interruptions, ill-defined goals – all the aspects of real activities, have been ignored. And error messages – there should not be any error messages. All messages should contain explanations and offer alternative ways of proceeding from the message itself. http://tc.eserver.org/32802.html http://tc.eserver.org/32802.html First-person shooter (FPS) games have become increasingly popular, and the player’s ability to accurately control their weapon is very important in these games. This study assesses players’ accuracy on eliminating targets in the FPS game Star Wars Battlefront II using three different input devices (mouse, Playstation 2 controller, and joystick) with two different rifle types (sniper and blaster rifle). No significant performance differences were found between input devices although subjectively participants believed they peformed the worst with the joystick. http://tc.eserver.org/32676.html http://tc.eserver.org/32676.html As UX professionals, we often take for granted the fact that our users will be dealing with a keyboard, mouse or track pad, and monitor. We think about users’ physical relationship with their digital devices very selectively, if at all. But, as we explore new human interface devices and incorporate new interactions into our designs, we have the opportunity to create deep connections between users and their technology. http://tc.eserver.org/32377.html http://tc.eserver.org/32377.html They're rarely helpful. Actually, they usually add insult to injury. But what would computing be without 'em? Herewith, a tribute to a baker's dozen of the best (or is that worst?). http://tc.eserver.org/32375.html http://tc.eserver.org/32375.html Why are virtual worlds increasingly relevant to technical communicators? What human factors influence the design of virtual worlds? This article explores these two important questions from a technical communication perspective. http://tc.eserver.org/32363.html http://tc.eserver.org/32363.html This study used an applied ethnographic research method to investigate human-computer interaction (HCI) between call center agents and agent-facing software in the context of contact-center culture. Twenty semi-structured interviews were completed, along with non-participant observation at two contact centers, one that followed a user-centered design (UCD) process for software development and another that did not. Agent productivity and satisfaction at the non-UCD center were hampered by poor task-UI integration, ambiguous text labels, and inadequate UI standardization. Agents required multiple applications to complete a single task, leading to long task times and cognitive strain. In contrast, the UCD center used a unified UI that reduced task times and decreased cognitive strain. In both centers, the workflow was reported to be stressful at times; however, management at both companies employed high involvement work processes that mitigated this stress. Implications for possible high-involvement UI design are considered and a strategy for applied ethnographic research is discussed. http://tc.eserver.org/32364.html http://tc.eserver.org/32364.html This paper describes a tool for log file recording and a method for quickly and easily analysing human-computer interaction with mobile devices. The tool logs screenshots and quantitative interaction data, such as number of clicks and timestamps. The analysing tool provides the ability to evaluate the interaction sequences and to export an MS Excel®-sheet for statistical analysis. To evaluate the tool, a usability study was conducted comparing the effectiveness of this tool in the laboratory and in the mobile context. Findings show that the tool is the first step toward a very effective, unobtrusive analysing method for user interaction in the mobile context. Combined with debriefing methods, it would be an optimized way for usability testing with mobile devices. http://tc.eserver.org/32238.html http://tc.eserver.org/32238.html I recently conducted a study into the helpfulness (or lack thereof) of zebra striping—the shading of alternate rows in a table or form. The study measured performance as users completed a series of tasks and found no statistically significant improvement in accuracy—and very little statistically significant improvement in speed when zebra stripes were implemented. http://tc.eserver.org/32073.html http://tc.eserver.org/32073.html A pretty interface doesn’t make an application or website. Even the early releases of Microsoft Vista looked amazing. The graphics, interface, and 'look' of the system were much more impressive than XP. But looks alone don’t make the package. It lacked in usability, creating error messages and not having a standard navigation schema. Users didn’t know if they were to click a button, an image, or text to complete their task. It is important to create a standardized and intuitive interface, as well as nice looking, so that users can navigate your site or application. http://tc.eserver.org/31907.html http://tc.eserver.org/31907.html Should the OK button come before or after the Cancel button? Following platform conventions is more important than suboptimizing an individual dialog box. http://tc.eserver.org/31916.html http://tc.eserver.org/31916.html Application usability is enhanced when users know how to operate the UI and it guides them through the workflow. Violating common guidelines prevents both. http://tc.eserver.org/31869.html http://tc.eserver.org/31869.html Computing technologies are becoming so familiar it can feel as if they have always been here. It is strange to think that the mouse, for instance, was invented by Doug Englebart in the seventies. He must encounter a degree of incredulity when he mentions this to people. “You invented the mouse? Really? How nice. Did you also invent the pen?” http://tc.eserver.org/31875.html http://tc.eserver.org/31875.html Over the past three decades of computer/human interaction, we’ve seen digital technology evolve from a curiosity to a convenience to an integral part of our everyday lives. For UX professionals, the demand for our skill sets and the opportunities to practice seem only to grow, whether we be designers or developers, usability specialists or information architects, working in fields as diverse as Web, mobile, desktop, and embedded software systems. The UX professions are at a stage that could very well be a tipping point—where the rapid rise of digital devices, services, and connectivity converge to create a massive need for UX professionals. The mobile space alone could generate demand that we can only begin to imagine. http://tc.eserver.org/31573.html http://tc.eserver.org/31573.html The Human Research Institute has conducted extensive studies of the proper form of Machine-Human Interaction (MHI). Most of our work has been summarized in our technical report series and was presented at the last global MHI symposium. This report summarizes the key findings in nontechnical language, intended for wider distribution than just the specialized designer machines. http://tc.eserver.org/31574.html http://tc.eserver.org/31574.html 编者：本书最后部分，作者比较了由机器开发的设计原则和由人总结的设计原则。下文中是机器对于如何与人交流的想法。 http://tc.eserver.org/31147.html http://tc.eserver.org/31147.html 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. http://tc.eserver.org/30479.html http://tc.eserver.org/30479.html A vital skill for designers is to notice fine detail in the other designs which form part of the technological ecosystem in which their design will live. For example, on Mac OS there are now two different styles of text entry fields for forms. One has square corners, and is used for general data entry. The other has rounded ends, and is used for entering searches. I was recently outraged to find a piece of software which used the rounded style for data entry. This kind of design vandalism muddies the rules which users would otherwise learn, and devalues all software on the platform. http://tc.eserver.org/30502.html http://tc.eserver.org/30502.html Throughout the history of the computer, human-computer interaction has taken many forms; from gears and levers to electronic desktops and virtual reality. Development of the computer has been driven by advances in technology making the computer smaller, cheaper, more powerful, but not necessarily easier to use. Today, the computer is ready for an evolutionary change from a number cruncher to a true communications medium. Sound, voice, and video are the future of the computer and technical communicators will become important in making this technology easier and more practical to use. http://tc.eserver.org/30448.html http://tc.eserver.org/30448.html An action possibility available in the environment to an individual, independent of the individual's ability to perceive this possibility. http://tc.eserver.org/30447.html http://tc.eserver.org/30447.html In the fields of HCI and interaction design the term is however most often used as 'making something material from something abstract.' In other words 'thingifying' something abstract (like an idea, a work practice, a social relationshiop) or at least making a representation of it. http://tc.eserver.org/30308.html http://tc.eserver.org/30308.html 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). http://tc.eserver.org/30180.html http://tc.eserver.org/30180.html This panel segment focuses on applying human-computer interaction (HCI) skills to the creation of online message help information for the IBM RSl6000 product. Online message help allows users to easily understand and diagnosis errors that they receive on the job, without them ever having to pick up a message manual. The HCI skills used in creating the online help were learned in the Introduction to HCI Usability class thut Rensselaer Polytechnic Institute offered as the first class of four offered in 1996 in their newly created HCI Certificate Program. http://tc.eserver.org/30011.html http://tc.eserver.org/30011.html This paper addresses the problem of designing service interaction for multiplatform operations and is based on a qualitative study of the services offered by a large retail Portuguese bank in four channels: bank branches, telephone, ATM, and Internet. The functionality of bank services across such channels was captured with essential use cases, which are technology free. When customers are free to decide in which channel they are going to get the service they need, customer experience (non-functional) requirements becoming ever more important. Essential use cases were extended to take account of such customer experience requirements. This additional information in essential use cases is very helpful, as it provides concrete and objective guidelines regarding the most suitable channel for implementing and offering each particular service. Doing essential use case modeling for multiplatform service interaction helps service providers allocate resources to the most likely channels that customers will use. It also allows them to identify areas of interaction experience that need to be improved if services offered are likely to be effectively used in the platform. http://tc.eserver.org/30008.html http://tc.eserver.org/30008.html Trust emerges from interaction. If trust in information systems is to be promoted, then attention must be directed, at least in part, to interaction design. This paper explores issues of trust in the interactions between users and systems from the perspective of interaction design. It considers a variety of pragmatic aspects in interaction design that impact user trust, including, predictability, interface stability, user control, and the match between expectations and performance. It critically examines contemporary design practices, such as adaptive interfaces, in terms of their impact on user trust. http://tc.eserver.org/30000.html http://tc.eserver.org/30000.html 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. http://tc.eserver.org/29822.html http://tc.eserver.org/29822.html In this paper, we introduce a general framework for product experience that applies to all affective responses that can be experienced in human-product interaction. Three distinct components or levels of product experiences are discussed: aesthetic experience, experience of meaning, and emotional experience. All three components are distinguished in having their own lawful underlying process. http://tc.eserver.org/29423.html http://tc.eserver.org/29423.html The trick is to make data-entry forms clear enough that workers understand what you require of them without having to ask. This understanding alone can drastically reduce the frequency of errors, but to turn that understanding into a payback, you'll have to design a label for each field that is truly obvious to the workers. Information designers call these clues "affordances", and if you're lucky enough to have technical writers or editors in your organization, you can probably enlist their aid in designing these clues. http://tc.eserver.org/29354.html http://tc.eserver.org/29354.html Discusses the various opportunities for eye-movement studies in future HCI research, and details some of the challenges that need to be overcome to enable effective application of the technique in studying the complexities of advanced interactive-system use. http://tc.eserver.org/29356.html http://tc.eserver.org/29356.html This is a summary of a talk on eyetracking for HCI students at Lancaster University in the UK. Feedback showed that students felt more able to conduct eye tracking research after attending the session. http://tc.eserver.org/28582.html http://tc.eserver.org/28582.html Why does a web site that rarely changes need HCI people? Learn about the experiences of a new employee, Josh Mittleman, which he shared with the UsabilityNJ meeting in October. http://tc.eserver.org/28496.html http://tc.eserver.org/28496.html Selections of 'least favorite' designs from graduate students of the George Mason University Department of Psychology. http://tc.eserver.org/28413.html http://tc.eserver.org/28413.html One of the most fundamental factors in designing for screen-based media is: No-one likes looking at a computer screen. http://tc.eserver.org/28367.html http://tc.eserver.org/28367.html Human-computer interaction in the large is an interdisciplinary area which attracts researchers, educators, and practioners from many differenf fields. Human-computer interaction studies a human and a machine in communication, it draws from supporting knowledge on both the machine and the human side. This paper is related to the human side of human-computer interaction and focuses on animations. http://tc.eserver.org/28323.html http://tc.eserver.org/28323.html 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. http://tc.eserver.org/28305.html http://tc.eserver.org/28305.html HCI Vistas presents cartoons that illustrate the interesting relationship between the human and computer. http://tc.eserver.org/28291.html http://tc.eserver.org/28291.html This website is meant to provide insights into various multi-disciplinary aspects of Human-Computer Interaction (HCI). It looks at this subject particularly from Indian perspective. HCI Vistas publishes at least two original articles every month. It offers latest research papers as downloads. It also presents Comptoons and survey reports. The website is meant to provoke new thinking in the HCI domain. http://tc.eserver.org/28191.html http://tc.eserver.org/28191.html The human factors specialist and the technical communicator find themselves making similar decisions or weighing similar issues. For example, often it is difficult to decide when to use symbols versus words. Sometimes you cannot shortcut and use pictures because pictures do not convey enough information. http://tc.eserver.org/27543.html http://tc.eserver.org/27543.html 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. http://tc.eserver.org/27542.html http://tc.eserver.org/27542.html This study reports a psychophysical comparison of four ergonomic mouse-type devices to the standard mouse. It was hypothesized that muscle activity transferred from the distal to proximal limbs for some of the ergonomic mice may result in increased load on the shoulders and declines in target acquisition performance. Results revealed a potential tradeoff between performance and safety with the devices as participants performed the best with the standard mouse but reported more wrist exertion with this device. http://tc.eserver.org/27531.html http://tc.eserver.org/27531.html This study examined the effects of mouse pad usage on performance of a target acquisition task. Results indicated no performance difference between three specialized mouse pads, a traditional mouse pad and no mouse pad. In addition, no significant differences were found between each of the mousing surfaces based on kinematic data. The results suggest that manufacturer claims of increased performance cannot be supported by empirical evidence. http://tc.eserver.org/27538.html http://tc.eserver.org/27538.html This study evaluates the usability of computer-based avionics system using a methodology described by Schvanevelt, Berringer & Leard (2004) which calculates the accessibility of information based upon the priorities users place upon the individual information sources. We discuss some of the unique usability issues facing engineers designing hardware and software for technically-advanced avionics systems. http://tc.eserver.org/27394.html http://tc.eserver.org/27394.html Usability is more and more critical to online success, but most developers have no formal training in it and most companies have no formal program for it. http://tc.eserver.org/27377.html http://tc.eserver.org/27377.html Whenever I hear someone making a general statement about what older people can or cannot do I think of my father-in-law. He's 80 years old and regularly runs marathons and competes in triathlons. He wins too. So I'm always suspicious about stereotypes involving technology and older users. http://tc.eserver.org/27361.html http://tc.eserver.org/27361.html 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. http://tc.eserver.org/27362.html http://tc.eserver.org/27362.html 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. http://tc.eserver.org/26984.html http://tc.eserver.org/26984.html The website of the Bay Area Chapter of the Human Factors and Ergonomics Society. http://tc.eserver.org/26959.html http://tc.eserver.org/26959.html 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。 http://tc.eserver.org/26953.html http://tc.eserver.org/26953.html I will examine this unfortunate side effect, Repetitive Strain Injury (RSI), of the Digital Age in this essay.

This paper provides the essence of the opinions and advice of the panelists and the questions from the audience. It is not meant to serve as a transcript of the discussion. Three key recommendations emerged from the panelists’ discussion: (1) be prepared for your search by developing a skill set you can use to market yourself to an employer, (2) be open to change and take advantage of opportunities as they arise, and (3) network. Each recommendation is discussed in its own section, followed by examples of how these recommendations helped the panelists in their own job searches. http://tc.eserver.org/25672.html http://tc.eserver.org/25672.html Students are always asking what they can do to position themselves for a professional career in human factors.

Within Human-Computer Interaction, the challenge is usually to give control of technology to users; be it through accessible design, or, more generally, by making paths clear and choices apparent. http://tc.eserver.org/25325.html http://tc.eserver.org/25325.html One hundred eight university and non university personnel participated in a comparison of single monitor, multi-monitor and multi-monitor with Hydravision display configurations. Respondents edited slide shows, spreadsheets and text documents in a simulation of office work, using each of the display arrays. Performance measures, including task time, editing time, number of edits completed, and number of errors made and usability measures evaluating effectiveness, comfort, learning ease, time to productivity, quickness of recovery from mistakes, ease of task tracking, ability to maintain task focus and ease of movement among sources were combined into an overall evaluation of productivity. Multi-screens scored significantly higher on every measure. http://tc.eserver.org/25239.html http://tc.eserver.org/25239.html The study reported here assessed the effects of isolation on attention. Is it true, in other words, that isolating an element in a visual display—moving an element away from other elements and surrounding it with white space—will inspire a greater allocation of attentional resources to the isolated element than to other elements on a page or screen? http://tc.eserver.org/25119.html http://tc.eserver.org/25119.html What are human factors?

Surveys are worth little, since those surveyed tend to tell you what they think you want to hear. Staff opinions are nice, but biased and they are not typical users. Heuristic (general guidelines-based) evaluation is helpful, but remains theoretical until tested on actual, representative users as they attempt to find information or perform tasks at your site. http://tc.eserver.org/24499.html http://tc.eserver.org/24499.html The proliferation of online information complicates information retrieval for users, who must first learn to use the information system itself. Multi-window online information systems compound this problem further by complicating an already-unfamiliar interface. However, research and practical experience suggest some design principles that can help to maximize the benefits of a multi-window system. http://tc.eserver.org/24498.html http://tc.eserver.org/24498.html An STC-funded study of computer users in an R & D organization attempts to identify users who reflect a high degree of productive integration of computers into workplace tasks. The study reveals user stratification along the lines of low-strategic and high-strategic users: users who choose to use computers to accomplish information and communication-oriented tasks. The study attempts to confirm this stratification by indicating that users identified in this way also use computers to perform a higher frequency of information-related computer behaviors, such as use of email, electronic information transfer, archiving, and software learning. Identifying users in this way can help writers and documention designers by providing models of integrated computer use. http://tc.eserver.org/24398.html http://tc.eserver.org/24398.html The cases of expert systems and intelligent agents illuminate two dimensions of the dwelling-place we have built for ourselves with our technologies. http://tc.eserver.org/24349.html http://tc.eserver.org/24349.html Planet HCI is a web aggregator of feeds from HCI-related blogs. http://tc.eserver.org/24115.html http://tc.eserver.org/24115.html A blog on user experience, HCI, and usability in India. http://tc.eserver.org/23911.html http://tc.eserver.org/23911.html This article discusses the results of surveys that indicate the IBM Lotus Sametime instant messaging product is a successful 'walk-up-and-use' application, requiring little documentation and no training. Users achieve a commercially significant level of performance within three months. In addition, over a much longer period, users continue to develop their skills (chat behaviors), social networks (chat partners), and attitudes toward the technology (reasons for using IM). This combination of attributes — ease of learning and sustained development of skills and strategies — is unusual in Human-computer interaction, and poses some unique challenges for creating a product that experienced users continue to find useful and usable. http://tc.eserver.org/23562.html http://tc.eserver.org/23562.html This paper reports the results of a survey of senior Business and Engineering majors conducted at the University of Cincinnati.

Participants completed the task in anonymous dyads as they were exposed to either Classical music, Punk music, or No Music. Results indicate that those in the Classical music condition performed better on the problem solving-task than those in the Punk music or No Music conditions. However, those listening to the Classical music offered more off-task comments during the task than those listening to No Music. Implications for website designers are discussed. http://tc.eserver.org/23305.html http://tc.eserver.org/23305.html One of the primary challenges confronting designers of mobile computing devices is the issue of efficient text entry. One potential solution is to group multiple letters onto single keys, similar to the T9 keyboard currently used on telephones. Two experiments examined the effects of perceptual grouping on soft keyboard transcription rates. Results from Experiment 1 showed significantly slower transcription rates for QWERTY keyboards with grouped keys. Results from Experiment 2 showed various levels of perceptual interference due to the different Gestalt grouping effects. These results indicate that perceptual grouping can negatively affect text entry performance, and placing multiple letters onto single keys reduces the speed at which users can transcribe words. http://tc.eserver.org/23300.html http://tc.eserver.org/23300.html Blog on all aspects of HCI, technology, design, usability, and its impact of society, users, ethics and life. http://tc.eserver.org/23278.html http://tc.eserver.org/23278.html 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. http://tc.eserver.org/23118.html http://tc.eserver.org/23118.html An increasingly popular component of modern graphical human-computer interfaces are graphical command buttons. Studies have shown that graphical command buttons can enhance user productivity. However, two factors, the time required to acquire a working knowledge of the graphical command set and the need for frequent use to maintain the knowledge limit the effectiveness of graphical command buttons as a user interface strategy. This study attempts to quantify the effects of four types of help (balloon style, a mouse documentation line at the bottom of the screen, a help browser, and hardcopy documentation) on the ability of novice users to acquire a working knowledge of a graphical command set. The study did not find any significant difference (based on the anova and manova tests) between the four treatments. http://tc.eserver.org/23075.html http://tc.eserver.org/23075.html The purpose of this study was to examine the effect of depth and breadth of web site structure on the user response time. http://tc.eserver.org/22809.html http://tc.eserver.org/22809.html AIPO es una organización abierta a todas las personas de nivel universitario e interesadas en la Interacción Persona-Ordenador de España e Iberoamérica. http://tc.eserver.org/22786.html http://tc.eserver.org/22786.html Job postings in Human-Computer Interaction, organized by geographic region. http://tc.eserver.org/22523.html http://tc.eserver.org/22523.html This site is meant to be an online museum of graphical interfaces, especially those old, obscure and in desperate need of preservation.
