This paper details the findings from a study of airline compliance with Department of Transportation (DOT) regulations requiring that persons with disabilities not be discriminated against in the pricing of airline travel. These regulations mandate that if an airline website is inaccessible for persons with disabilities, the airline must charge the same price that is available on the website and may not charge a fee for purchasing tickets over the phone. To evaluate compliance, the websites of leading airlines were examined for accessibility in terms of the ability to check flight schedules and order tickets. Among the four airlines with barriers to accessibility on their websites, a series of phone calls were made by researchers to assess whether the DOT regulations would be followed. Two of the airlines, USAirways and United, practiced discriminatory pricing, even after being made aware of the regulations, in over one-third of the phone calls. This paper details the findings from the study and analyzes the data in terms of website accessibility, civil rights for travelers with disabilities, and policy implications. 相似文献

ABSTRACTThe Michigan State University (MSU) Libraries' Website has a case of TMI: too much information organized by librarians for librarians. Finding relevant information about various library services, including the 24/7 Distance Learning Support Line, and access points to scholarly resources is often cumbersome, and given the limited time and staffing available in Web Services, it was impractical to embark on a comprehensive Website redesign. Instead, the implementation of two systems, LibAnswers and the A–Z Database List in LibGuides v2 CMS, served as a means for addressing the TMI issue and improving the usability of the MSU Libraries' Website. This case study will map the MSU Libraries' experience of implementing the LibAnswers and the A–Z Database List from early vision to launching the end product, as a means for resolving the “too much information” issue and improving the usability of the library's Website. 相似文献

Information on Wheels is an outreach service of the Medical College of Wisconsin Libraries. A mobile cart loaded with professional books and journals is taken weekly to the hospital unit and outpatient clinic of the Milwaukee County Hospital and Froedtert Hospital. The targeted audience is primarily nurses since (1) their job demands usually allow little time flexibility, and (2) they make up the largest percentage of hospital health care professionals. After one year of service, a survey was undertaken to determine the usefulness of the service. The results were very positive. One comment repeated was, "This is an excellent service because is provides easy access to pertinent information to people who are sometimes too busy or don't think to go to the library." 相似文献

SUMMARY Electronic resources (ER) constitute an increasingly significant portion of library collections, both in usage and cost. It is vital to design easy, efficient access to these collections as users have other online options to meet their information needs. Thus, an important goal for ER librarians is to provide a usable ER site. Formal usability testing is a powerful tool to help librarians create the most useful site for their customers. This chapter will cover the basic components of usability testing and suggest ways in which ER librarians can lead efforts in their institution to improve the customer experience with library Web sites. ER librarians can create buy-in from library staff for usability testing as a worthwhile method to improve access to ER through involvement in the process and sharing results of the testing. The responsibilities of ER librarians vary from one institution to another, but all share in the mission of the profession to serve its customers' information needs. This chapter addresses the possibilities of usability testing as a force to maximize the user experience with the collections ER librarians manage. 相似文献

ABSTRACT The new, social Web is fun and easy to use. The same cannot usually be said of library Web sites and digital resources. Libraries would benefit from incorporating aspects of the Read/Write Web into their services. This article examines how libraries currently erect barriers to service and provides an example of how these barriers could be eliminated by the creation of a social library research environment. 相似文献

Contrary to system-controlled multimedia learning environments, hypermedia systems are characterized by a high level of interactivity.
This interactivity is referred to as learner control in the respective literature. For several reasons this learner control
is seen as a major advantage of hypermedia for learning and instruction. For instance, learner control might increase students’
interest and motivation, facilitate adaptive instruction, or provide affordances for active and constructive information processing.
In this paper we analyze the instructional potentials of learner-controlled hypermedia environments as well as possible reasons
for the ambiguous results of studies that have aimed at determining the effectiveness of hypermedia learning. According to
our analysis, the potential effectiveness of self-controlled learning with hypermedia might be difficult to demonstrate due
to (1) usability problems (i.e., disorientation, distraction, cognitive overload), (2) moderating learner characteristics
(i.e., prior knowledge, self-regulatory skills, cognitive styles, and attitudes towards learning), (3) a lack of conceptual
foundations, and (4) methodological shortcomings of many hypermedia studies. The findings reviewed in this paper and the corresponding
claim that hypermedia may be effective only if used in a sensible way are used to derive a couple of guidelines for further
research on hypermedia learning. 相似文献

The strongest tradition of IR systems evaluation has focused on system effectiveness; more recently, there has been a growing interest in evaluation of Interactive IR systems, balancing system and user-oriented evaluation criteria. In this paper we shift the focus to considering how IR systems, and particularly digital libraries, can be evaluated to assess (and improve) their fit with users’ broader work activities. Taking this focus, we answer a different set of evaluation questions that reveal more about the design of interfaces, user–system interactions and how systems may be deployed in the information working context. The planning and conduct of such evaluation studies share some features with the established methods for conducting IR evaluation studies, but come with a shift in emphasis; for example, a greater range of ethical considerations may be pertinent. We present the PRET A Rapporter framework for structuring user-centred evaluation studies and illustrate its application to three evaluation studies of digital library systems. 相似文献

Advances in the publishing world have emerged new models of digital library development. Open access publishing modes are expanding their presence and realize the digital library idea in various means. While user-centered evaluation of digital libraries has drawn considerable attention during the last years, these systems are currently viewed from the publishing, economic and scientometric perspectives. The present study explores the concepts of usefulness and usability in the evaluation of an e-print archive. The results demonstrate that several attributes of usefulness, such as the level and the relevance of information, and usability, such as easiness of use and learnability, as well as functionalities commonly met in these systems, affect user interaction and satisfaction. 相似文献
