Résumé
Training is one of the main domain applications of Virtual Reality (VR). Simulation and visual realism provide training situations very close to practice with real systems but at reduced cost and with greater safety. Furthermore VR offers the possibility of change time or space scales, visualize from different perspectives, experience inaccessible real environments, under the control of the user, without risks, progressing at her own pace. This allows to develop skills and to have confidence to work in a later stage in real conditions with real equipment. Many interaction technologies are now more widely available and affordable. But generally devices are conceived for "standard" people leaving behind people with impairments and further accentuating the digital gap. In this paper, we present our work in the development of an accessible wheelchair simulator designed to allow children with multiple disabilities to familiarize themselves with the wheelchair, and practitioners to better understand children capabilities.
