Cette thèse s'inscrit dans le domaine de l'ingénierie des Environnements Virtuels pour l’Apprentissage Humain (EVAH). Les jeux épistémiques numériques (JEN) sont une catégorie des jeux sérieux dédiés à la résolution de problèmes complexes, pluridisciplinaires et non-déterministes afin de proposer des situations d'apprentissage plus authentiques.La première partie de la thèse est consacrée à l’exploration des dimensions spatiales, temporelles et sociales des interactions dans un JEN. Des expérimentations ont été menées en milieu écologique et ont montré un apport pédagogique par une augmentation de l'engagement des apprenants. La conception des prototypes expérimentés a mis en évidence que le développement informatique des interactions immersives d'un EVAH demeure actuellement réservé à des spécialistes en Réalité Mixte ou Virtuelle (RMV).Ainsi la seconde partie de la thèse a été dédiée à la proposition d'un environnement de développement (MIREDGE). Une interface de programmation visuelle permet aux développeurs de modéliser des interactions sans connaissance spécifique en RMV par réutilisation de blocs. Des expérimentations ont permis d'évaluer l'efficacité et l'efficience de MIREDGE pour le profil des développeurs RMV ainsi que celui des développeurs non-initiés à la RMV. Les développeurs RMV ayant une nécessité à poursuivre leur algorithme au-delà de la programmation visuelle, MIREDGE permet une génération automatique de code dans leur moteur de jeu. L'approche garantie une large compatibilité avec les environnements de développement et les périphériques, ouvrant ainsi des perspectives sur l'étude de logiques d'interactions universelles. / This thesis is in the field of the virtual environments for human learning. Digital Epistemic Games (DEG) are a category of serious games dedicated to solving complex, multidisciplinary and non-deterministic problems. The objective of DEGs is to propose authentic learning situations in terms of interactions so that learners can construct and anchor knowledge in their context of use.The first part of the thesis is devoted to exploring spatial, temporal and social dimensions of DEG interactions. Experiments were conducted in ecological environment and showed an educational contribution through an increase in the learner engagement. The design of the prototypes showed that the development of the immersive interactions of a virtual environment for human learning currently remains reserved for specialists in Mixed Reality or Virtual (MVR).So the second part of the thesis was the proposal of a development environment named MIREDGE. A visual programming interface allows developers to model interactions without specific knowledge in MVR through the reuse of blocks. Experiments have evaluated the effectiveness and efficiency of MIREDGE for specialist and non-specialist developers in MVR.As specialist developers in MVR have to continue their algorithm beyond visual programming, MIREDGE allows automatic generation of code providing the corresponding script being totally re-editable in their game engine. The MIREDGE approach ensures wide compatibility with development environments and peripherals. This opens perspectives on the study of the logics of universal interactions.

[pt] Jogos pervasivos móveis são jogos que combinam os mundos real e virtual em um espaço híbrido, permitindo interações não apenas com o mundo do jogo virtualmente criado, mas também com o ambiente físico que envolve os jogadores. A Internet de Coisas Móveis (IoMT) especifica situações em que os dispositivos na Internet das Coisas (IoT) podem ser movidos ou se moverem de forma autônoma, mantendo conectividade remota e acessibilidade de qualquer lugar na Internet. Seguindo o enorme sucesso dos recentes jogos pervasivos móveis e a iminente expansão de IoT, nós fornecemos uma integração para toda a tecnologia envolvida no desenvolvimento de um jogo pervasivo móvel que incorpora dispositivos IoT. Também propomos um jogo móvel pervasivo que avalia os benefícios da união de ambos os campos. Este protótipo de jogo explora maneiras de aumentar a experiência dos jogadores através de mecânicas pervasivas, aproveitando a motivação dos jogadores para realizar tarefas de sensoriamento. O jogo também incorpora aplicações sérias na jogabilidade, tais como a localização de instalações e serviços. / [en] Mobile pervasive games are a game genre that combines the real and virtual worlds in a hybrid space, allowing interactions with not only the virtually created game world, but also with the physical environment that surrounds the players. The Internet of Mobile Things (IoMT) specifies situations in which devices on the Internet of Things (IoT) can be moved or move autonomously, while maintaining remote connectivity and accessibility from anywhere on the internet. Following the huge success of recent mobile pervasive games and the coming IoT boom, we provide an integration for all the technology involved in the development of a mobile pervasive game that incorporates IoT devices. We also propose a mobile pervasive game that evaluates the benefits of the union of both fields. This game prototype explores ways of increasing the experience of players through pervasive mechanics while taking advantage of the player s motivation to perform sensing tasks. It also incorporates serious applications into the gameplay, such as the localization of facilities and services.

Proceeding from a framing of theater as collaborative storytelling, I argue for defining role-playing games as a kind of performance and for their value in structuring experiential and participatory theater. Building on the impulse at the heart of experiential and immersive theater to place the audience within the world of the performance and center their experience, I explore what it means for theater artists to cede control over how audiences make meaning of their work in favor of letting narrative emerge from the participation of the audience during the performance event. I propose a framework called pervasive performance that merges theatrical frames and methods with pervasive gaming, which expands the magic circle of play and blurs the distinction between the game and everyday life. This union of ideas puts audience members in contact with one another and allows them to be playful and co-author the overall performance experience. Further, the blurring of the performance and everyday life transforms audience members’ relationship to the real world and gives them space to imagine and experiment with other worlds and ways of being in them. I devised an alternate reality game (ARG) at UMass Amherst in May 2023, and in my thesis I analyze this project and the process of creating it as a case study in pervasive performance.
