Conference Paper
Cognitive load (CL) when using Virtual Reality (VR) requires more experimental inputs, especially to determine how VR affects human psychophysiology depending on the task. Classifying humans' physiological variations in a controlled setup is essential. We randomly assigned 92 participants to three experimental conditions: control, stereoscopy, and...

Our ultimate purpose is to train individuals, in virtual environments, to handle critical situations. One of these critical situations are dilemmas. They refer to situations that lead to negative consequences whichever is the choice made by the protagonist. In critical contexts, it is crucial to know how to handle this kind of situations in order t...
Article
Although virtual reality (VR) has many applications, only few studies have investigated user acceptance of this type of immersive technology. We propose an extended version of the Technology Acceptance Model (TAM) that addresses some aspects of VR. Our model includes variables from the TAM, user experience, variables specific to VR, and variables r...

The artificial intelligence used for opponent non-player characters in commercial real-time strategy games is often criticized by players. It is used to discover the game but soon becomes too easy and too predictable. Yet, a lot of research has been done on the subject, and successful complex behaviors have been created, but the systems used are to...
Conference Paper
Full-text available
The use of storytelling for learning is widely approved and encouraged. Yet, in virtual environments for training, there are difficulties to build a story when there is no global control over the course of events. We present in this paper an approach called diegetization. Supported by structuralist narrative theories, this approach aims to dynamica...
Conference Paper
Full-text available
Some working contexts have such a complexity that initial training cannot prepare the workers to handle every kind of situation they migh encounter. This lack of training comes at a high price and leads to productivity loss or low quality manufacturing in industry. Above all, it may be the cause of major accident in high-risk domains. To prevent th...

Technological maturity allows, nowadays, to plan increas-ingly complex applications. However, on the one hand, such complexity increases the difficulty to propose simultaneous, pedagogical and nar-rative control as well as some freedom of actions. On the other hand, that complexity makes difficult the tracking of a learner's path. To over-come this...

In high risk industries, risk management training has become a major issue. It requires not only to teach rules and procedures, but also to promote a real understanding of the risks that are at stake and to train learners to work in degraded situations (stress, difficult co-activity, damaged equipment...). In this paper, we present the outcomes of...

In complex simulations, multi-agents systems allow to model virtual humans with an explicit cognitive process representation. However, this cognitive process is hard to model and is therefore generally simplified in an application-dependant way. In order to improve the realism of individual and collective behavior of these agents, we propose to int...
