This paper describes a video annotation tool based on a new and flexible model, that gives several perspectives over the same video content. The model was designed in a way that allows having multiple views over the same video data, enabling users with different requirements to have the most appropriate interface. These views, video-lenses, highlight a(More)
In this paper we describe a visualization system for an emergency simulation. We start by presenting a flooding emergency case scenario and all the elements that are involved in it. Then we describe the design decisions that were made in order to create a credible representation of the scene. This includes using a game engine to render the scenario using a(More)
The introduction of interaction technology in museum settings requires special care in different aspects including the relations with the different participants (public, artists, and curators), and the ability of the technology to provide rewarding experiences over extended periods of time for a demanding audience. This paper describes a hardware and(More)
