Active Table-of-Contents Control for Content Navigation and Customization 
This report illustrates the design of a novel user interface feature to provide simple and rapid navigation and user customization of the contents of a complex, multipart document. Within a performancesupport application for classroom teachers, the objective was to provide an efficient and instantly learnable scheme for direct user control over the parts to be included in the document as well as quick access to any part of the document. The design relies on the techniques of instructive interaction, an innovative approach for making user interfaces self-teaching even when they incorporate novel or non-standard features.

The concept of an affordance was coined by the perceptual psychologist James J. Gibson in his seminal book The Ecological Approach to Visual Perception. The concept was introduced to the HCI community by Donald Norman in his book The Psychology of Everyday Things from 1988. There has however been ambiguity in Norman's use of the concept, and the concept thus requires a more elaborate explanation.

Assessing the Usability of a User Interface Standard
User interface standards can be hard to use for developers. In a laboratory experiment, 26 students achieved only 71% compliance with a two page standard; many violations were due to influence from previous experience with non-standard systems. In a study of a real company's standard,developers were only able to find 4 of 12 deviations in a sample system, and three real products broke between 32% and 55% of the mandatory rules in the standard. Designers were found to rely heavily on the examples in the standard and their experience with other user interfaces.

A Breakdown of the Psychomotor Components of Input Device Usage
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.

Many usability problems are instances of what we call 'conceptual gaps.' A conceptual gap arises because of some difference between the user’s mental model of the application and how the application actually works.If the gap is large enough, it can stop the user’s work. For example, a user who wants to search the web for free local concerts may not know how to formulate a query that will yield this information. The gap between the search engine’s syntax and the user’s understanding of that syntax may prevent the user from accomplishing their goal.

A Car for All - or Mobility for All? Part I
Population aging and environmental concern are two important factors that will effect the design of vehicles in the future. In response to the potential conflict between them, the authors propose a shift in focus from individual vehicles to transport services, from '€˜A Car for All'€™ to '€˜Mobility for All'€™, and offer strategies, scenarios and case studies of how this might be achieved. New service and vehicle typologies are introduced and discussed, and an area of future research and development is identified.

Defining an Effective Electronic Performance Support System
Most businesses have seen a dramatic increase in the amount of information employees require to perform tasks. Traditional approaches to training such as paper documentation, instructor-led training, or computer-based training (CBT) may have been effective in the past, but are not suitable to respond to the rapid changes in time, cost, and delivery of information today’s marketplace requires. At Unisys Corporation we have piloted an electronic performance support system that provides self-instruction for our clients at their point of need.

Designing Minimalist Principles Into User Interfaces
Designing a user interface using minimalist principles for guided exploration can reduce the amount of paper and text necessary to document the system. Graphics in the interface can help the user grasp the concepts of the system, while dialog boxes, status information, and error messages can aid in recognition of success and recovery from errors. Online help can then be used as a backup for users if they get stuck. Reducing text and paper can reduce translation and printing costs, making this process very attractive.

This article discusses turn signals and how they are used. Turn signals improve safety because they give people time to react and they reduce driving ambiguity. However, they are only effective when people actually use them. Several lessons are applied to web usability.

Electronic Voting: Usability, Communication, Trust
Beyond just the undeniable importance of a usable form and voting mechanism, is the need to consider the comfort and satisfaction of voters dealing with sometimes radically changed voting systems, especially when the move is from paper-based voting systems to electronic systems.

Empirical Evaluation of a Popular Cellular Phone's Menu System: Theory Meets Practice 
A usability assessment entailing a paper prototype was conducted to examine menu selection theories on a small screen device by determining the effectiveness, efficiency, and user satisfaction of a popular cellular phone's menu system. Outcomes of this study suggest that users prefer a less extensive menu structure on a small screen device. The investigation also covered factors of category classification and item labeling influencing user performance in menu selection. Research findings suggest that proper modifications in these areas could significantly enhance the system's usability and demonstrate the validity of paper-prototyping which is capable of detecting significant differences in usability measures among various model designs.

Ergonomic Mice: Comparison of Performance and Perceived Exertion
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.

What do customers want from our software and documentation? They want to accomplish tasks, and to obtain information about tasks, as quickly and painlessly as possible. Do they also expect to be entertained along the way? No, not when there is work to be done. Years of usability analysis in the software industry indicates very clearly that clarity and ease-of-use is topmost on the minds of software users.

Users have goals when they use software applications. Their goal is NOT to 'use' the application. Their goal is to complete an activity or task using the application. Performance support is defined as providing users what they need to be successful in completing their activity or task when they need it – at the point of need. Technical communicators can benefit from incorporating performance support elements into their work, even if they are not creating a performance support system.

"More is Less" for Many Home Entertainment System Users
The days of a single remote for the TV or cable box are long gone. Like ants at a picnic, the control pads have invaded the nation's coffee tables. But unlike ants, remotes evolve rapidly. Not only are there more, but many sport added buttons and complexity added each time a model is upgraded with new features.

Several new user interface technologies and interaction principles seem to define a new generation of user interfaces that will move off the flat screen and into the physical world to some extent. Many of these next-generation interfaces will not have the user control the computer through commands, but will have the computer adapt the dialogue to the user's needs based on its inferences from observing the user. This article defines twelve dimensions across which future user interfaces may differ from the canonical window systems of today: User focus, the computer's role, interface control, syntax, object visibility, interaction stream, bandwidth, tracking feedback, interface locus, user programming, and software packaging. Keywords: Agents, Animated icons, BITPICT, DWIM, Embedded help, Eye tracking, Generations of user interfaces, Gestural interfaces, Help systems, Home computing, Interactive fiction, Interface paradigms, Noncommand based user interfaces, Prototyping, Usability heuristics, Virtual realities, Wizard of Oz method.
