“…Our observations were consistent with earlier results indicating the importance of informative, well-designed link text (Ceaparu and Shneiderman, 2004). As screen-reader users often do not listen to the entire text of a link, pertinent terms should be placed as early as possible in links (Theofanos and Redish, 2003).…”

a b s t r a c tNumerous studies have investigated task performance times for selection from hierarchical menus, with structures containing many choices at each of a few levels (broad, shallow structures) generally outperforming structures containing fewer choices at each of many levels (narrow, deep structures). To see if these results applied to blind users who rely on screen reader software for computer access, we replicated an earlier published study, using 19 blind screen-reader users. Consistent with earlier studies, broader, shallow hierarchies outperformed narrow, deep hierarchies. Task performance times and hypertext lostness measures were correlated. Although further work will be needed to understand specific determinants of task performance rates, these results support the use of broad, shallow menus for blind as well as sighted users.

ObjectivesTo elucidate current issues related to health statistics dissemination efforts on the Internet in Indonesia and to propose a new dissemination website as a solution.Methods:A cross-sectional survey was conducted. Sources of statistics were identified using link relationship and Google™ search. Menu used to locate statistics, mode of presentation and means of access to statistics, and available statistics were assessed for each site. Assessment results were used to derive design specification; a prototype system was developed and evaluated with usability test.Results:49 sources were identified on 18 governmental, 8 international and 5 non-government websites. Of 49 menus identified, 33% used non-intuitive titles and lead to inefficient search. 69% of them were on government websites. Of 31 websites, only 39% and 23% used graph/chart and map for presentation. Further, only 32%, 39% and 19% provided query, export and print feature. While >50% sources reported morbidity, risk factor and service provision statistics, <40% sources reported health resource and mortality statistics. Statistics portal website was developed using Joomla!™ content management system. Usability test demonstrated its potential to improve data accessibility.Discussion and conclusion:In this study, government’s efforts to disseminate statistics in Indonesia are supported by non-governmental and international organizations and existing their information may not be very useful because it is: a) not widely distributed, b) difficult to locate, and c) not effectively communicated. Actions are needed to ensure information usability, and one of such actions is the development of statistics portal website.

“…Previous research (Card et al 2001, Blackmon et al 2002, Brumby and Howes 2008 has demonstrated that people have lower success rates and require more time to complete the task when they are presented with weak scent compared to high scent. Ceaparu and Shneiderman (2004) report study results in which users' performance nearly doubled and frustration levels dropped when the wording of link-labels was changed.…”

New Review of Hypermedia and Multimedia

Following information scent has been established as a metaphor to describe a user's behaviour while navigating an information space by successively selecting hyperlinks. This metaphor suggests that users assess the profitability of following a particular hyperlink based on its perceived semantic association with their goal. The purpose of this paper is to study how information scent, this important attribute of hypermedia navigability, influences concurrently four aspects of users' behaviour while exploring a website: (1) distribution of attention; (2) confidence in choice of link; (3) efficiency; and (4) effectiveness. It was found that in webpages with high scent, users were significantly more focused, confident of their choices, efficient and effective compared to webpages with ambiguous scent. The findings of the study are discussed in comparison with results obtained from a previously conducted analysis using InfoScent Evaluator (ISEtool), a tool that has been proposed to facilitate scent evaluation of websites. This comparison provided support for the effectiveness of ISEtool in indicating potential scent-related navigability problems. We argue that such a tool-based approach can facilitate hypermedia design by reducing the resources and expertise required, and by providing the necessary flexibility for practitioners.
