Visualizing dynamic graphs are challenging due to the difficulty to preserving a coherent mental map of the changing graphs. In this paper, we propose a novel layout algorithm which is capable of maintaining the overall structure of a sequence graphs. Through Laplacian constrained distance embedding, our method works online and maintains the aesthetic of individual graphs and the shape similarity...
Based on general researches regarding visualization theory and application practices, this paper concentrates on the visualization techniques in business process simulation (BPS) and presents a review of visualization in BPS. It gives the procedures of BPS, summarizes the three kinds of typical visualization techniques. According to the BPS steps, different visualization usage in different BPS phase...
In typical scenarios of construction planning, engineers communicate ideas primarily using paper based media (e.g. drawings) spread across table surfaces. Even though the traditional communication approach offers convenient interaction among participants, the media used are cumbersome to handle. Moreover, they present static information that cannot reflect the dynamic nature of a jobsite. These limitations...
Co-located collaborative tasks allow teams to leverage the skills of each individual member. While numerous guidelines exist to develop visualizations for individuals working on desktops, very little is known about how groups of individuals interpret and comprehend diverse types of visual constructs on larger displays. To study whether group size impacts the collective understanding of relationships...
This paper proposes virtual metaphors, appearance features, gestures and animations that can be used for avatars in Computer Supported Collaborative Learning three dimensional Environments. Our aim is to enrich avatars' support to nonverbal communication, as well as to enhance and improve students' collaborative interaction. Within this context, by implementing virtual avatars representations and...
E-Learning has the potential for providing significant improvements in accessibility and opportunity to learning because of its distributed nature. Educators have been using storytelling as an effective mode of teaching since long time. Collaborative activities promote conversation among the learners, and this assists learning by providing each one of them with a slightly different view of the subject...
New and innovative opportunities for teaching and learning are offered by MUVEs [multi user virtual environments]. Built on gaming technologies MUVEs are primarily a synchronous 3D social platform operating without goals and objectives wherein all content is user created and owned. They are increasingly being used by educators all around the globe as a new and more advanced platform for 3/4D data...
