The paper describes an animation approach where synthetic vision is used for navigation by a digital actor. The vision is the only channel of information between the actor and its environment and offers a universal approach to pass the necessary information from the environment to an actor in the problems of path searching, obstacle avoidance, and internal knowledge representation with learning and forgetting characteristics. For the general navigation problem, we propose a local and a global approach. In t

In the context of cognitive and behavioural therapies, the use of immersion technologies to replace classical exposure often improves the therapeutic process. As it is necessary to validate the efficiency of such a technique, both therapists and VR special ...

This paper presents an evaluation of the benefits and user acceptance of a multimodal interface in which the user interacts with a game-like interactive virtual reality application "The Enigma of the Sphinx". The interface consists of a large projection screen as the main display, a "magic wand", a stereo sound system and the user's voice for "casting spells". We present our conclusions concerning "friendliness" and sense of presence, based on observations of more than 150 users in a public event

An innovative way of animating actors at a high level based on the concept of synthetic vision is presented. The objective is simple: to create an animation involving a synthetic actor automatically moving in a corridor avoiding objects and other synthetic actors. To simulate this behaviour, each synthetic actor uses a synthetic vision as its perception to the world and so, as the unique input to its behavioural model. This model is based on the concept of displacement local automata (DLA), which is similar
