Cette thèse propose des modèles, méthodes et outils destinés aux game designers de jeux thérapeutiques. Le problème de conception le plus fondamental des jeux thérapeutiques est le gameplay, c'est-à-dire des objectifs de jeu et des actions que le joueur doit effectuer pour atteindre ces objectifs. Dans un jeu thérapeutique, le gameplay doit à la fois produire l'effet thérapeutique et motiver le patient à suivre son protocole. Les problèmes sous-jacents de celui-ci sont l'évaluation médicale et ludique du jeu, et l'échange de connaissances entre game designers et experts santé. Nous proposons une méthode de game design de jeu thérapeutique allant de la définition du problème à l'évaluation. Cette méthode intègre les autres solutions que nous proposons, notamment le modèle player/game/therapy et une méthode de formalisation du gameplay. / This PhD thesis explores the field of therapeutic games in order to propose methods and tools for the game designer of such games. The most fundamental design problem of therapeutic games is the gameplay, ie. the game objectives and the actions the player does to address the objectives. In therapeutic game, the gameplay must, at the same time, provide the therapeutic effects and motivate the patient to follow his protocol. The sub-problems of this are 1. the two-fold evaluation (medical and motivation), 2. the exchange of knowledge between game designers and health experts. We propose a therapeutic game design method which begins with the problem definition and ends with the two-fold evaluation. This method integrates the other solutions we propose, particularly the player / game / therapy model and a method to formalize the gameplay.

Le jeu casual est un phénomène majeur de l’industrie vidéoludique, pourtant il reste peu étudié et mal considéré. Les quelques définitions scientifiques recensées présentent des divergences importantes, ainsi qu’un décalage par rapport aux jeux produits. Les modèles théoriques en design de jeu, centrés sur le gameplay, semblent inadéquats face à ce phénomène. En utilisant le modèle du praticien réflexif de Donald Schön, l’objectif de notre recherche est d’apporter un nouvel éclairage sur le jeu casual grâce au savoir professionnel des designers de jeux. Notre approche est qualitative, d’inspiration phénoménologique : nous avons recueilli l’expérience de huit designers de jeux par l’intermédiaire d’entretiens semi-dirigés proches du récit de pratique. Nos résultats montrent que les concepts utilisés dans les modèles vidéoludiques traditionnels restent pertinents pour définir le jeu casual, mais demandent à être retravaillés afin de rendre compte des mutations de l’expérience de jeu. Ainsi, un challenge dans un jeu casual n’est pas un obstacle mais une opportunité d’action pour le joueur. De plus, la progression se fait par la variation des challenges plutôt que par l’augmentation de la difficulté. Ensuite, certains concepts qui semblaient pertinents pour définir les jeux casual, tels que la fiction positive, ont été rejetés par nos participants. Enfin, notre étude a permis de rassembler des informations sur le rôle du designer de jeu casual et le contexte dans lequel il exerce, ce qui permet d’expliquer certaines causes de la vision péjorative du jeu casual. / Casual games are one of the main phenomena in the video game industry, but remain under-explored and are not highly regarded. Scientific definitions are scarce, inconsistent, and often disconnected from actual games. Further, theoretical models for game design, centered on gameplay, often fall short in defining casual games. The objective of this study is to use Donald Schön's model of the reflective practitioner to shed a new light on casual games through the collection of professional knowledge of game designers. This study follows a qualitative approach with phenomenological inspiration. Eight one-on-one semi-structured interviews were conducted with casual game designers who were asked to provide a narrative of their professional practice. Results show that traditional game design concepts remain relevant for understanding and defining casual games, but need to be reworked in the light of new experiences and contexts in gaming. Namely, challenge is no longer synonymous with obstacle, but should be considered as an opportunity of a player’s action. Progression should be based on the variation of challenges instead of increasing difficulty. In addition, participants rejected some concepts that were previously considered appropriate for defining casual games, like positive fiction. Finally, this study provides insight into the role of casual game designers and the context of their work, which can help explain the often negative perception of casual games.

[pt] A complexidade inerente ao desenvolvimento de um jogo digital demanda a formação de equipes interdisciplinares. Para atingir os resultados esperados nessa tarefa, os profissionais envolvidos criam diversos protótipos durante o processo de design, cada um testando um ou mais aspectos do objeto final. Um dos componentes mais importantes a ser avaliado em um game é a mecânica do jogo, porque é principalmente dela que emerge o desafio numa partida. Para que o designer possa avaliá-la adequadamente nos seus diversos estágios de desenvolvimento é preciso que tais protótipos sejam funcionais, o que usualmente se define como protótipos de teste. Diversos tipos de protótipos podem cumprir esta função, desde os mais rudimentares até os digitais de alta fidelidade. Sendo a mecânica do jogo um dos primeiros elementos a serem elaborados em um projeto de design de games, tanto protótipos de papel, quanto os protótipos digitais de baixa fidelidade podem ser utilizados logo no início do processo. No entanto, os estudantes de design nem sempre possuem a capacitação técnica adequada ou mesmo um conhecimento elementar em programação computacional para construir protótipos digitais. Uma alternativa, portanto, é construir protótipos a partir de materiais mais rudimentares, um procedimento que, para este fim, é menos usual na indústria de jogos do que a criação de protótipos digitais. Por meio de um experimento com alunos do curso de Design de Games, esta pesquisa teve por objetivo investigar se a mecânica de jogos de diferentes gêneros pode ser criada e avaliada por meio de protótipos analógicos mais simples, mas que não usam programação computacional. Paralelamente, a pesquisa ainda nos permitiu indagar se, na construção destes protótipos, o aluno de design de games trabalharia apenas intelectualmente na concepção projetual ou se também exerceria, de alguma forma, uma atividade produtiva. Notou-se que, por serem protótipos rápidos, os protótipos analógicos são adaptativos e permitem mudanças instantâneas, possibilitando que os estudantes exercitem a prática do design por meio de um processo iterativo de geração de ideias, construção de protótipos, testes avaliativos e recriações. Deste modo, concluiu-se que tais protótipos não são somente instrumentos de concepção, mas também de produção, propiciando a prática essencial do design, que é fundamentalmente inventiva e experimental. A contribuição deste trabalho é fornecer uma nova alternativa de aprendizagem da prática projetual a estudantes de design de games, já que os resultados da pesquisa demonstraram que tais protótipos – que possuem semelhanças físicas com alguns jogos simples, como os de tabuleiro – também podem ser utilizados para criar e desenvolver games mais complexos. / [en] The intrinsic complexity of the process of developing a digital game turns the formation of multidisciplinary teams inevitable. To meet the planned aims, during the design process the professionals involved create a variety of prototypes, each one testing one or more aspects of the final object. One of the more important components to be evaluated in a game is its mechanics due its key-role in making a match really challenging. In order to be make its mechanics properly appraisable by the designer in the different stages of development, it is necessary that the prototypes were functional, in other words, were reliable prototypes of test. There are many kinds of prototypes capable of fulfilling this condition, ranging from the most rudimentary to the high fidelity digital ones. Since the game s mechanics is one of the first elements to be elaborated in a game design project, either paper prototypes as well as the low fidelity digital prototypes can be used from the very beginning of the design process. Besides that, the students of design frequently do not possess the necessary technical knowledge on computational programming to allow them constructing digital prototypes, even if the necessary knowledge is elementary. An alternative, therefore, is building prototypes from rudimentary materials, which is, however, a less usual proceeding in the game industry that the creation of digital prototypes. The aim of the present research, through an experiment among the students of the discipline of Games Design, was to investigate if the mechanics of different genres of games could be created and evaluated by simpler analogical prototypes, without using computational programming. At the same time, this work has allowed us to inquire if, during the construction of theses prototypes, the game design students work only intellectually on the project conception or if, somehow, they also practice a productive activity. We have found out that, for being quick prototypes, they are very adaptable and permit instant changes, turning possible for the students to practice the design process through an interactive process of generating ideas, prototypes building, evaluative tests and recreations. The conclusion we achieve thus is that theses prototypes not only are conception instruments but also production ones, promoting the essential practice of design, which is basically inventive and experimental. The contribution of the present study is to offer a learning alternative on the project practice for game design students, once the results of the research demonstrated that the prototypes – which present physical similarities to some simple games, as the board games – can also be used in the creation and development of more complex games.
