N1 - 99 N2 - The DEFFINUM RVRC 4.0 project is a customer-relations training system that combines virtual reality (VR) with generative artificial intelligence (GAI). Through a serious game, a GAI-driven non-player character (NPC) engages in natural-language dialogue with the learner, while an authoring tool lets instructors freely create contextualised scenarios (customer type, history, environment, etc.). The platform targets the acquisition of key psychosocial skills – professional posture, service orientation, emotional regulation, negotiation – via interactive role-play and factual analysis of actions. GAI provides dynamic personalisation of interactions and generates a mission report, leaving final assessment to the trainer to comply with GDPR, the AI Act and ethical guidelines. An experimental protocol involving 2,000 learners and 40 instructors (October 2025 – February 2026) will compare VR versus flat-screen modalities, different GAI models and effects on disengaged learners, aiming to measure performance gains and pedagogical transferability across diverse sectoral and regional contexts UR - https://shs.cairn.info/revue-innovations-2025-HS1-page-95?lang=en&redirect-ssocas=7080 ER -
