“…This researcher may be involved by asking the participant questions and providing assistance or only taking notes and remaining silent during the trial. In order to determine the participant responses to the system, another commonly employed technique is the use of think-aloud exercises during which the participant is asked to speak their thoughts as they use the system (Simpson, 1990;Jaspers et al, 2004). Whether retrospective (after the event) or concurrent (during the event), the use of think-aloud exercises provide an insight into the mind of the user, supplying researchers with high-quality usability data helping to understand and anticipate potential problems (Dillow, 1997;van den Haak et al, 2003).…”

A dietary assessment website for use in the primary healthcare setting has been developed. The website allows patients, referred from their GP, to self-report their dietary intake. Data from the website feeds to a dietitian who develops individualised dietary advice for the patient. The aim of this paper is to describe the usability testing of the dietary assessment website with its potential users. Testing was broken into two phases. Fortytwo free-living adults with metabolic syndrome volunteered, 17 completed phase one and 10 completed phase two, with a 64% rate of completion. Phase one participants spoke aloud as they progressed through the selfadministered dietary assessment website under researcher observation. Observed difficulties in website use and need for assistance was recorded and the website underwent modifications between phases. Only four participants in phase 1 required large amounts of assistance. Phase two participants progressed through the website without observation or using the think-aloud protocol. This simulated the environment in the GP practice within which the website was to be implemented. All participants completed pre-and post-use questionnaires assessing feelings toward use, computer experience and problems encountered. Questionnaires were thematically analysed for relationships between website use and participant feelings. Time taken to use the website was recorded automatically. Website features were grouped into 'action classes' e.g. selecting food items, and times taken were calculated for each class. Comparisons (t-tests) were made between the action classes for the two phases. Average time taken to select the food items was 31mins and 24mins for phase one and two respectively. Total time taken was approximately 1 hour and varied by four minutes between phases. Time taken to complete the dietary assessment was comparable to a face-to-face diet history with a dietitian. The website was found to be highly user-friendly with little assistance being required for most levels of computer experience. Dietary management may be overlooked by GPs, yet by offering different methods of accessing dietitians, management may improve. completed phase one and 10 completed phase two, with a 64% rate of completion.Phase one participants spoke aloud as they progressed through the self-administered dietary assessment website under researcher observation.

“…The site was piloted before it was made fully available to the intended group (Hochheiser & Shneiderman, 2001;Shneiderman, 1998); through a carefully designed questionnaire the team received feedback on the usabilityof the site (Simpson, 1990). Therefore the discussion board was selected for it user-friendly design.…”

It was establkhed early on in this study that aLanguage, Literacy and Culture Program (LLC) site is needed to keep the community connected. A communi&-centered design was considered, and implemented in the fall of1999. The current study was implemented to assess why the site failed and what could be done to revive it.The findings of the current study indicated that the community did not develop as expected despite the team's effort to follow a community-centered approach. In this paper we consider the reasons for the site's failure, and what could be done to revitalize the community. Through surveys, and interviews it was determined that the communiy needed more active participation from the moderator and faculty. They also required a more interactive and better developed design, and special care should be taken to train the members who need it on the use oftechnology involved.
