This paper surveys the set of techniques developed in Computer Graphics for animating human walking. First, we focus on the evolution from purely kinematic \knowledge-based" methods to approaches that incorporate dynamics constraints, or use dynamics simulations to generate motion. Then, we review the recent advances in motion editing, that enable the(More)
In this paper, we propose a new approach to simulate the small intestine in a context of laparoscopic surgery. The ultimate aim of this work is to simulate the training of a basic surgical gesture in real-time: moving aside the intestine to reach hidden areas of the abdomen. The main problem posed by this kind of simulation is animating the intestine. The(More)
In this paper, we propose an approach based on visualization to support the teacher to observe the students' activities. After comparing the teaching in classical rooms and in e-learning systems, we present some visualization techniques used in various domains. The paper then focuses on visualization techniques in order to help the teacher to better(More)
In this paper, we present a system dedicated to the simulation of various physically-based and mainly deformable objects. Its main purpose is surgical simulation where many models are necessary to simulate the organs and the user's tools. In our system, we found convenient to decompose each simulated model in three units: The mechanical, the visual and the(More)
The work reported here takes place in the educational domain and deals especially with observation of pedagogical activity. User behavior is observed through the raw traces (log files) of their activity from multiple sources. The main point of this paper deals with a very important stage, generally not described: the preparation of an observed experiment by(More)
The development of the tools of Business Process Management (BPM) arises from the spread of the notion of process in the managemen tu niverse. The application of BPM to strategic processes is blocked by the tools' rigidity. They have difficulty in handling the processes of which the structure is not clearly defined and/or those for which all information is(More)
