Apports perceptivo-cognitifs des avatars dans des environnements virtuels familier, semi-familier et non familier

摘要

The fundamental studies of perceptivo-cognitive type on the contributions of the avatars in the virtual scenes are generally carried out in situations of laboratory. For our own projects, we needed to evaluate these contributions in complex industrial scenes. This document is the synthesis of this applicative study.The study presented treats of the appreciation of the avatars carrying qualitative information ; they do not carry the principal information but populate virtual environments. This study aims to better know information than these avatars convey by their presence in order to reinforce the messages contained in the application and to avoid the misinterpretations or ambiguity they could bring if this factor is not controlled.The principal results of the experimentation are the following: ? In any type of virtual environment, the avatars bring realism and "life". In a nonfamiliar environment, they also allow to provide indications on the work and the activity in environnement, in particular with their working clothes and actions. ? Nevertheless, to be appreciated and effective, these avatars will be sufficiently realistic and their behaviors must be relevant compared to environnement. Mobility alone is not enough, their actions must be coordinated, fluid and be centered on an identifiable objective of task. The clothes of the civil avatars must also be considered because it conveys a significant psychosociological dimension.
