Family Centered

This is the latest article in a series of research on the family-centered design concept. The theoretical context was revisited and expounded to support its usefulness in conjunction with a user-centered design approach within distinct application domains. A very important contribution is applied through the development of the instruments—website capture, a public testing platform, results processing and the Web Content Accessibility Guide 2.1 recommendation tool—to conduct unmoderated remote testing of user interfaces that corresponds to the requirements of general digitalization efforts as well as the response to current and future health risks. With this set of instruments, an experiment was conducted to address the differences in usage, and performance-wise and user-based evaluation methods, of the eDavki public tax portal, among two generations, adults and elderly citizens, and between an original and an adapted user interface that respects accessibility and other recommendations. The differences found are further discussed and are congruent to particularities that have been modified within interfaces.

The Web

Web services are an emerging technology that has attracted much attention from both the research and the industry sectors in recent years. The exploitation of Web services as components in Web applications facilitates development and supports application interoperability, regardless of the programming language and platform used. However, existing Web services development standards do not take into account the fact that the provided content and the interactive functionality should be accessible to, and easily operable by, people with disabilities. This chapter presents a platform named myWebAccess, which provides a mechanism for the semi-automated “repair” of Web services' interaction characteristics in order to support the automatic generation of interface elements that conform to the de facto standard of the Web Content Accessibility Guidelines 2.0. myWebAccess enhances interaction quality for specific target user groups, including people with visual and motor disabilities, and supports the use of Web services on diverse platforms (e.g., mobile phones equipped with a browser). The Web developers can build their own design templates and the users of myWebAccess can create a personalized environment containing their favourite services. Thus, they can interact with them through interfaces appropriate to their specific individual characteristics.

“Pluggable user interfaces” is a software concept that facilitates adaptation and substitution of user interfaces and their components due to separation of the user interface from backend devices and services. Technically, the concept derives from abstract user interfaces, mainly in the context of device and service control. Abstract user interfaces have been claimed to support benefits such as ease of implementation, support for User Centered Design, seamless user interfaces, and ease of use. This paper reports on experiences in employing pluggable user interfaces in the European project i2home, based on the Universal Remote Console framework, and the Universal Control Hub architecture. In summary, our anecdotal evidence supports the claims on the benefits, but also identifies significant costs. The experience reports also include some hints as to how to mitigate the costs.

Design And Testing

This is an opinion piece about the relationship between the fields of human-computer interaction (HCI), and artificial intelligence (AI). The ultimate goal of both fields is to make user interfaces more effective and easier to use for people. But historically, they have disagreed about whether "intelligence" or "direct manipulation" is the better route to achieving this. There is an unjustified perception in HCI that AI is unreliable. There is an unjustified perception in AI that interfaces are merely cosmetic. This disagreement is counterproductive.This article argues that AI's goals of intelligent interfaces would benefit enormously by the user-centered design and testing principles of HCI. It argues that HCI's stated goals of meeting the needs of users and interacting in natural ways, would be best served by application of AI. Peace.

High Level

AbstractModel Based User Interface Development offers the possibility to design User Interfaces without being concerned about the underlying implementation. This is achieved by devising models at a high level of abstraction, thus creating the potential for involving users or domain experts to achieve a user-centered design process. Obtaining a running interactive application from such models usually requires several model transformations. One of the current problems is that while a user interface is generated after these transformations, other parts of the interactive system such as the application logic need to pre-exist or they must be written manually before the interface can be tested in a realistic scenario. This leaves the domain experts dependent on programmers and increases the time between iterations. In this paper we work with Query Annotations, which were previously used only for modeling at low levels and for generating fully functional interfaces, and we aim to generalize them for the high-level modeling approach called Discourse Modeling. The direct expected benefit of this generalization is the possibility to generate complete, readily testable interactive prototypes, rather than just their user interfaces. In addition, Query Annotations can serve as the mapping between the various levels of abstraction and bring to the domain experts a better understanding of the transformation process, as well as the possibility to modify the interfaces and models directly.

( Part 1 of this three-part series on Best Practices appeared in the winter 2007 issue.) The IBM Global Services Usability Engineering National Practice (UENP) group has focused on the application of industry-based, user-centered design (UCD) best practice techniques and principles to solve user interface and usability problems in a variety of industry contexts. UCD techniques and principles have been applied across different industries, application domains, and user interface styles. We have learned valuable lessons with regard to consistent and effective use of a rigorous, proven, and repeatable design process in system and Internet projects. The use of our design process results in cost-effective solutions for satisfied customer users. Although the findings generally apply to many styles of user interfaces and systems, this article shares some of our lessons, experiences, best practices, and results with a focus on recent Web-based projects.

Usability Evaluation Methods

A high-fidelity prototype of an extended voice mail application was created. We tested it using three distinct usability testing paradigms so that we could compare the quantity and quality of the information obtained using each. The three methods employed were (1) heuristic evaluation, in which usability experts critique the user interface, (2) think-aloud testing, in which naive subjects comment on the system as they use it, and (3) performance testing, in which task completion times and error rates are collected as naive subjects interact with the system. The three testing methodologies were roughly equivalent in their ability to detect a core set of usability problems on a per evaluator basis. However, the heuristic and think-aloud evaluations were generally more sensitive, uncovering a broader array of problems in the user interface. Implications of these findings are discussed in terms of the costs of doing the evaluations and in light of other work on this topic.
