This paper discuses the use of video analysis software and computer generated animations for student activities. The use of artificial video affords the opportunity for students study phenomena for which a real video may not be easy or even possible to procure, using analysis software with which the students are already familiar. We will present three example activities: two lab activity "add o...

This paper presents a new model for trajectories in video sequences using mixtures of motion fields. Each field is described by a simple parametric model with only a few parameters. We show that, despite the simplicity of the motion fields, the overall model is able to generate complex trajectories occuring in video analysis.

In this paper a collaborative music game for two pen tablets is studied in order to see how two people with no professional music background negotiated musical improvisation.
