The purpose of this paper is to identify the problems to solve in order to simulate real-time crowds in a virtual environment. We try to classify these problems and study how they have been addressed until now by the research community and our lab in particular. We then discuss for each problem what are the future challenges and how to address them.
The increasing use of virtual reality in the treatment of phobias translates in a just as expanding need for realism in its scenes and characters. Virtual characters need to seem gifted with intelligence. A first step in achieving this is by giving them the possibility to interact with real people. In this paper we present an eye-tracking based method to obtain interactive virtual characters. We use...
This article presents a simple and intuitive way to represent the eye-tracking data gathered during immersive virtual reality exposure therapy sessions. Eye-tracking technology is used to observe gaze movements during virtual reality sessions and the gaze-map chromatic gradient coding allows to collect and use these important information on the subject's gaze avoidance behavior. We presents the technological...
This paper presents a solution to interactive navigation planning and real-time simulation of a very large number of entities moving in a virtual environment. From the environment geometry analysis, we deduce a structure called navigation graph, which is the base to our method. After the description of this structure, we introduce a set of algorithms dedicated to answer navigation queries with a set...
