Serious games (SGs), the confluence of e-learning and videogames, have been developing very fast these past years. Indeed, SGs combine aspects of tutoring, teaching, training, communication and information, with entertainment elements derived from videogames, in order to capture people’s attention for purposes that go beyond pure entertainment. However, the creation of a SG for educational purposes and professional training is a very time-consuming and expensive process. The challenge is to combine learning objectives and fun characteristics with an acceptable budget and time. For these reasons, we propose an interactive authoring environment, called EDoS (Environment for the Design of Serious Games), designed to assist SG authoring team.

The EDoS is based on three models:(1) a formal domain-specific model of pedagogical objectives (competencies, knowledge, and behaviours) at which a SG aims;(2) IMS-LD-SG, an extension of the IMS-LD specification made specifically for SGs and (3) a task model formalized with CTT (Concurrent Task Trees) used to formalize Human-Computer Interactions sequences for screens of the game.
