ABSTRACT In the past decade, academic libraries have struggled with the design of an effective library home page. Since librarians' mental models of information architecture differ from those of their patrons, usability assessments are necessary in designing a user-centered home page. This study details a usability sequence of card sort and paper and online survey methods conducted at the Auraria Library, which serves the University of Colorado Denver, the Metropolitan State College of Denver, and the Community College of Denver. The three top complaints about the existing Web page included information overload, lack of visual cues and guidance, and difficulty getting to what students knew was the heart of the library's Web page: online resources. Using qualitative and quantitative data from the card sorting sessions, the Web librarian, under the direction of the Web Advisory Committee, was able to create a more user-centered home page. Unique to this study are the use of undergraduate students in creating test instruments and a means of gathering information about what students value most in their library's home page. 相似文献

Web portals act as a single point of access to information and services relevant to person's work or personal interests. Market research findings related to Croatian web context report that nowadays horizontal information portals are the most visited sites. Whether they reach their aim of facilitating users’ access to diverse resources and to which extent, remains an open question. In this paper, this issue is addressed by two case studies conducted for summative assessment of Croatian horizontal information portals. Approach assembled expert inspection and user assessment that integrated a number of empirical methods into laboratory-based testing. We report that the results of inspection method were not in agreement with the ones obtained from user test methods. Although differences of this kind have been reported elsewhere, these were not as evident as in these studies. What is very interesting and represents a main contribution of the research is that in both rounds of evaluations this outcome is very sharp and clear. This suggests that we should conduct both kinds of assessments as they seem to be complementary. Evaluation provided some general findings and know-how from the experience and we believe that many readers, both practitioners and researchers, can learn from it. 相似文献

Many government organizations use web heuristics for the quality assurance of their websites. Heuristics may be used by web designers to guide the decisions about a website in development, or by web evaluators to optimize or assess the quality of an existing website. Despite their popularity, very little is known about the usefulness of heuristics for web designers and evaluators. In this study, five government heuristics are examined with special attention to their presumed use, content, validity, and presentation format. Our findings raise questions about the usability of heuristics for web design and web evaluation purposes. More research into the actual use and effects of web heuristics is needed. 相似文献

Today there are thousands of electronic shops accessible via the Web. Some provide user-friendly features whilst others seem not to consider usability factors at all. Yet, it is critical that the electronic shopping interface is user-friendly so as to help users to obtain their desired results. This study applied heuristic evaluation to examine the usability of current electronic shopping. In particular, it focused on four UK-based supermarkets offering electronic services: including ASDA, Iceland, Sainsbury, and Tesco. The evaluation consists of two stages: a free-flow inspection and a task-based inspection. The results indicate that the most significant and common usability problems have been found to lie within the areas of ‘User Control and Freedom’ and ‘Help and Documentation’. The findings of this study are applied to develop a set of usability guidelines to support the future design of effective interfaces for electronic shopping. 相似文献

This paper focuses on usability evaluation of information and communication technologies applications in education (ICTE applications).
Various classes of teaching and learning systems are discussed in terms of technologies used and pedagogical approaches. Their
usability is analyzed according to various dimensions and the impact of system usability on the learning effectiveness is
studied. We argue that various classes of ICTE applications such as multimedia/hypermedia applications, open educational environments
and CSCL environments, based on different theoretical perspectives, require fundamentally different approaches in evaluating
their usability. The paper is structured as follows: an overview of different usability evaluation approaches is presented
first, followed by a discussion on applicability of these techniques in various categories of teaching and learning computer
systems. Typical case studies that engage both usability experts and users themselves (students and teachers) are also discussed.
The objective is to describe both the methods, and the way to apply them effectively in order to certify the usability of
an ICTE application with respect to its teaching and learning objectives. 相似文献

This study used two successive phases of usability testing to evaluate two different versions of a Communication 430 course LibGuide. The first version of this guide had a longer, more visually complex navigation menu, with more course-related research information directly accessible through this menu. The second version had a shorter, less complex menu that offered less directly accessible information. Twenty-four of the 33 students enrolled in the class (73%) tested either one version or the other for usability in completing tasks that simulate course-related research assignments, ultimately indicating they found the longer navigation menu more usable. This paper may be the first to describe the engagement of students enrolled in a course in testing a LibGuide dedicated specifically to that course. As such, it will be of interest to many academic librarians and instructional design professionals. 相似文献
