The article presents a study which examines the usability of multi-touch tablet computer by adults with down syndrome for work-related tasks. It states that usability testing methodology was used during the investigation. Results show that adults with down syndrome can use multi-touch devices effectively for workplace-related tasks, formal computer training can influence the performance of the participant, and that password usability remains a challenge for Down syndrome patients.

When hard-to-use computers cause users to become frustrated, it can affect workplace productivity, user mood and interactions with other co-workers. Previous research has examined the frustration that students and their families face in using computers. To learn more about the causes and measure the severity of user frustration with computers in the workplace, we collected modified time diaries from 50 workplace users, who spent an average of 5.1 hours on the computer. In this exploratory research, users reported wasting on average, 42 – 43% of their time on the computer due to frustrating experiences. The largest number of frustrating experiences occurred while using word processors, email and web browsers. The causes of the frustrating experiences, the time lost due to the frustrating experiences, and the effects of the frustrating experiences on the mood of the users are discussed in this paper. Implications for designers, managers, users, information technology staff and policymakers are discussed. [ABSTRACT FROM AUTHOR]

Abstract: User frustration with information and computing technology is a pervasive and persistent problem. When computers crash, network congestion causes delays, and poor user interfaces trigger confusion there are dramatic consequences for individuals, organizations, and society. These frustrations, not only cause personal dissatisfaction and loss of self-efficacy, but may disrupt workplaces, slow learning, and reduce participation in local and national communities. Our exploratory study of 107 student computer users and 50 workplace computer users shows high levels of frustration and loss of 1/3–1/2 of time spent. This paper reports on the incident and individual factors that cause of frustration, and how they raise frustration severity. It examines the frustration impacts on the daily interactions of the users. The time lost and time to fix problem, and importance of task, strongly correlate with frustration levels for both student and workplace users. Differences between students and workplace users are discussed in the paper, as are implications for researchers. [Copyright &y& Elsevier]

This paper reports on a study of 50 homepages in the Mid-Atlantic United States to determine what accessibility problems exist. The 50 homepages were evaluated using both the U.S. government’s Section 508 guidelines as well as the Web Accessibility Initiative’s (WAI) Priority Level 1 of the Web Content Accessibility Guidelines (WCAG). According to both sets of guidelines, 49 out of 50 sites were found to have accessibility problems, although some of the accessibility problems were minor and easy to fix. There are two troubling findings from this study. The Web sites that had the most accessibility problems were organizations in the Web development and information technology field, which ideally should be the leaders in making the Web more accessible. The Web accessibility software testing tools, which are available to assist people in making their Web sites more accessible, are flawed and inconsistent and require large numbers of manual checks, which many developers may not be able to do. More people need to become aware of the topic of Web accessibility, and the testing tools need to be improved so that once people are aware, it is easier for them to move their sites toward full accessibility.
