With the advance of mobile computing and wireless technology, a user's intent to interact with the interface of a mobile device is motivated not only by its intuitional operation, but also by the emotional perception induced by its aesthetic appeal. A graphical interface employing icons with suitable visual effect based on the users' emotional…

The purpose of this exploratory study was to determine how the use of multimedia components, such as graphics, audio and video, in online courses was related to perceived learner satisfaction and learning effectiveness. The use of retrospective data provided self reported perceived satisfaction measures and total score representing objective…

Learning environments commonly offer aids to address learners' lack of knowledge or skills. However, learners are not or sub-optimally using these aids when these are non-embedded or segregated (Aleven, Stahl, Schworm, Fischer, & Wallace, 2003; Clarebout & Elen, 2006). This lack of optimal usage has been related to variables as…

The purpose of this study was to determine whether or not the use of solid modeling software increases participants' success in solving a specified technical problem and how visualization affects their ability to solve a technical problem. Specifically, the study sought to determine if (a) students' visualization skills affect their problem…

Educational hypertexts usually include graphical overviews, conveying the structure of the text schematically with the aim of fostering comprehension. Despite the claims about their relevance, there is currently no consensus on the impact that hypertext overviews have on the reader's comprehension. In the present paper we have explored how…

The increasing complexity of human body models enabled by advances in diagnostic imaging, computing, and growing knowledge calls for the development of a new generation of systems for intelligent exploration of these models. Here, we introduce a novel paradigm for the exploration of digital body models illustrating cerebral vasculature. It enables…
