Medical prac-titioners usually encounter usability difficulties while using a health information system like other systems. There are different usability factors, which are expected to influence systems’ usability. Errors preventions, patient safety and privacy are vital usability factors and should not be ignored while developing a health information system. This study is based on a comprehensive analysis of published academic and industrial literature to provide the current status of health information systems’ usability. It also identifies different usability factors such as privacy, errors, design and efficiency. Usability factors are then assessed. Those factors are further examined through a questionnaire to study the priorities of them from medical practitioners’ point of view in Saudi Arabia. The statistical analysis shows that the privacy and errors are very critical than the other usability factors. The study results further revealed that availability and response time are the main challenges faced by the medical practitioners when using the HIS. However, flexibility and customizability were claimed to ease the use of the HIS. In addition, a number of statistical correlations were established. Overall, the study findings seemed helpful to designers and implementers to consider these factors for successful implementation of HIS.展开更多

Nevertheless, many tools, which could help them to access the web, are available. E-commerce websites have been also intensively and widely used. The e-commerce market in Saudi Arabia will hit $13.3 billion by 2015. This huge investment requires e-commerce websites to be accessible by different types of users. This paper explores the tools that usually used by disabled users while using the web. It also discusses a number of available tools that help designers, developers and testers to assess web accessibility. It also evaluates the accessibility of 3 popular Arab e- commerce websites using 5 accessibility testing tools;namely Achecker, TAW, Eval Access, MAUVE and FAE. This research has found that Most accessibility guidelines are covered by Achecker tool. Navigation, readability, input assistance and timing are the common found accessibility problems while assessing the accessibility of the targeted websites. It has been also revealed that HTML can influence accessibility evaluation as HTML errors are considered as accessibility problems. It has been clearly observed that improvements are needed for better web accessibility, although some tools did report a small number of accessibility problems for some websites.展开更多

Usability of software applications is one factor that reduces security and privacy up to a substantial level. This paper examines the differences between usability factors and aspects related to security and privacy. A clear understanding of gaps between these two opposing factors has been presented in this paper. In addition, an account of efforts carried out to bridge these gaps has also been presented. We have divided these efforts into the categories of guidelines, frameworks and use of technology. The fields of e-banking and social networks have been considered specifically for identification of gaps in these particular fields.展开更多
