The usability problems of CSCW system mainly come from two aspects of limitation. On the higher level, it lacks sufficient simulation of the use-context influenced by social, political and organizational features; on the lower level, it lacks suitable measurement and description of basic collaborative behavior happened in common cooperative activities. However, the traditional task-based user interface...
Usability is an important measurement of software quality. Effective usability evaluation method and analysis technique on usability data always help to achieve high usability. A numerical measurement in usability evaluation can facilitate the comparison between different designs of product prototype. In this paper, we propose a simulation approach based on FSM to abstract the user interface rules...
Most undergraduate IT education in China, including computer science, informatics engineering and automation, always ignores the role of usability engineering in product design at present. This paper examines the development and trend of usability engineering aspect research in Western countries, describes the close and important relationship between usability engineering and IT (especially in computer...
Usability evaluation is traditionally used in the late stage of software development process. However, to some high-cost complex distributed collaborative software, such late-usability-evaluation or single-user-oriented usability inspection are unsuitable in modern situation. The early stage of evaluation always relies on a task model (interface model) to simulate the actions of real user. However,...
Usability is a three-dimensional quality of software product, encompassing efficiency, effectiveness and satisfaction. Satisfaction always relies on subjective judgment, but on some degree, the measurement of efficiency and effectiveness is able to be objectively calculated by some approaches, which can help designers to compare different prototype design candidates in the early stage of product development...
