71	Conception et développement d’interactions immersives pour jeux sérieux / Design and development of immersive interactions for serious games Loup, Guillaume 04 December 2017 (has links) 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.

73	The cooperative future of game development : A phenomenon of collaboration between producers and consumers in the video game industry / Den kooperativa framtiden för dataspelsutveckling : Ett fenomen av samarbete mellan producenter och konsumenter inom dataspelsindustrin Gustafsson, Viktor, Höglund, Gustav January 2016 (has links) Independent developers and large-scale development studios - commonly seen as the Davids and Goliaths of the video game industry - are moving closer together. Powerful software frameworks, traditionally reserved for professional developers and only available through expensive licenses, are becoming free to use for consumers. By sharing their tools instead of keeping them for themselves, companies can utilize the combined talent of whole communities and monetize on that talent through royalties and other indirect fees. This paper describes how the video game industry has developed in recent years to allow for this change in business strategy and examines how the industry can continue to evolve because of this. The result of a Delphi study based on interviews with game developers both inside and outside the industry point toward a future of increased intermingling and sharing of knowledge and resources, characterized by more producer-consumer collaborations and closer relationships between companies and their communities. By adopting free-to-use business models and sharing powerful, proprietary software with their consumers, companies are lowering the point of entry for aspiring developers and thereby dissolving the traditional narrative of “we and them” that has existed between independent developers and established studios in the past. / Oberoende utvecklare och storskaliga utvecklingsstudior - vanligtvis betraktade som tv-spelsindustrins David och Goliath - rör sig allt närmre varandra. Kraftfulla mjukvaruramverk som traditionellt sett varit reserverade för professionella utvecklare och som tidigare endast varit tillgängliga genom kostsamma licenser blir i allt större utsträckning gratis att använda för konsumenter. Genom att dela med sig av sina verktyg istället för att hålla dem för sig själva så kan företag nyttja den kombinerade talangen hos sociala nätverk knutna till sina produkter och generera intäkter genom royalties och andra indirekta avgifter. Denna uppsats beskriver hur tv-spelsindustrins utveckling på senare år har möjliggjort denna affärsstrategiska förändring och hur industrin kan fortsätta att utvecklas som en följd av detta. Resultatet av en Delfistudie baserad på intervjuer med spelutvecklare både inom och utanför industrin pekar mot en framtid av ökat samspel och delande av kunskap och resurser. Detta karaktäriseras av fler samarbeten mellan producenter och konsumenter samt närmre relationer mellan företag och deras konsumentnätverk. Genom att ta till sig affärsmodeller som bygger på gratis-att-använda-principer och att dela med sig av avancerad, äganderättsskyddad mjukvara med sina konsumenter, så sänker företag ingångströskeln för aspirerande spelutvecklare. Därigenom löser företagen upp den traditionella “vi och dem”-relationen som tidigare existerat mellan oberoende utvecklare och etablerade studior. producer-consumer collaboration indie modding business model game development game engine participatory culture outsourcing innovation community platforms producent-konsumentsamarbeten indie modding affärsmodell spelutveckling spelmotor deltagarkultur outsourcing innovation konsumentnätverk Media and Communication Technology Medieteknik
74	Generating Procedural Environments using Masks : Layered Image Document to Real-time environment Eldstål, Emil January 2019 (has links) This paper will explore the possibilities of using an automated self-made procedural tool to create real-time environments based on simple image masks. The purpose of this is to enable a concept artist or level designer to quickly get out results in a game engine and to be able to explore ideas. The goal of this thesis was to better understand how you can break down simple ideas and shapes into more complex details and assets. In the first part of this thesis, I go over the traditional workflow of creating a real-time environment. I then go on and break down my tool, what it does and how it works. I start off with a Photoshop file, make tools in Houdini and then utilize those in Unreal for the end result. I also argument about the time-saving possibilities with these tools. From the work, I draw the conclusion that these kinds of tools save a lot of time for repeating tasks and the creation of similar environments.

75	Neeuklidovské vykreslování ve VR / Non-Euclidean Rendering in VR Bobuľa, Matej January 2021 (has links) The main goal of this master's thesis is to research different approaches of rendering geometries and spaces in virtual reality. Learn more about the terms, non-Euclidean geometry and non-Euclidean spaces, their origin and different principles used in video game industry to simulate such geometries or spaces. Based on the research, a selection of an optimal API is needed for the implementation of such application. Application is designed to run on desktop computers with Microsoft Windows operating system. Application, in it's core, is a video game and the main goal of the player is to successfully complete each and every level of the game. These levels are designed in a specific way so that they each individually represent some form of non-Euclidean geometry or space.
76	MonoGenjin : En praktisk undersökning av 2D spelmotors- och spelutveckling Källberg, Viktor, Källman Andersson, Tobias January 2022 (has links) Spelindustrin är gigantisk och kontinuerligt växande, där detta inkluderar spelutveckling samt spelande av spel. Detta medför att en betydande mängd akademiker i sina yrkesliv kommer att beröra ämnesområdet spelutveckling. Trots detta faktum finns det en avsaknad av akademisk litteratur som behandlar ämnesområdet spelutveckling, specifikt med ett IS-perspektiv. För att fylla avsaknaden ämnar denna undersökning utöka det specifika konceptet inom spelutveckling som är “skapande av en 2D-spelmotor med tillhörande spel”. Att spela innebär hedonistiska upplevelser. Gäller denna hedonism också vid spelutveckling? Vilka utmaningar och vilken problematik uppstår vid utveckling av en spelmotor? För att utreda detta används en kvalitativ undersökning med en induktiv metodik via forskning genom design (eng. Research through Design, RtD) tillsammans med kollaborativ autoetnografi (Collaborative Autoethnography, CAE). Detta skapar ett unikt perspektiv som används för att producera välmotiverad vägledning för introduktion till ämnesområdet. Datainsamling utgörs av loggbok och dagbok där dessa används för att reflektera kring problem, utmaningar, framgångsfaktorer samt hedonistiska upplevelser inom processen. Undersökningens bakomliggande teori är baserat på Hedonic-motivation system adoption model (HMSAM) samt kriterier för utvärdering av ett lyckat RtD-projekt. Resultaten visar att spelutveckling är en komplicerad process, där egenskaper av spelutveckling identifierats och som bildat riktlinjer som förbereder akademiker inför framtida forskning och arbete. / The gaming industry is gigantic and continuously growing, which includes game development and gaming. This means that a significant number of academics will touch on the subject area of game development during their professional lives. Despite this fact there is a lack of academic literature which deals with the subject area of game development, specifically with an IS perspective. To fill the gap, this study aims to expand the specific concept in game development that is “creation of a 2D game engine with an associated game”. Gaming involves hedonistic experiences. Is this also associated with game development? What challenges and problems arise when developing a game engine? Answering this involves a qualitative study with an inductive methodology via Research through Design (RtD) together with Collaborative Autoethnography (CAE). This creates a unique perspective that is used to produce well-motivated guidance for introduction to the subject area. Data collection consists of a journal and diary where these are used to reflect on problems, challenges, success factors and hedonistic experiences within the process. The study’s underlying theory is based on the Hedonic-motivation system adoption model (HMSAM) and criterias for evaluating successful RtD projects. The results show that game development is a complicated process, where characteristics of game development have been identified which developed guidelines that prepare academics for future research and work.

78	Implementation and Analysis of Co-Located Virtual Reality for Scientific Data Visualization Jordan M McGraw (8803076) 07 May 2020 (has links) <div>Advancements in virtual reality (VR) technologies have led to overwhelming critique and acclaim in recent years. Academic researchers have already begun to take advantage of these immersive technologies across all manner of settings. Using immersive technologies, educators are able to more easily interpret complex information with students and colleagues. Despite the advantages these technologies bring, some drawbacks still remain. One particular drawback is the difficulty of engaging in immersive environments with others in a shared physical space (i.e., with a shared virtual environment). A common strategy for improving collaborative data exploration has been to use technological substitutions to make distant users feel they are collaborating in the same space. This research, however, is focused on how virtual reality can be used to build upon real-world interactions which take place in the same physical space (i.e., collaborative, co-located, multi-user virtual reality).</div><div><br></div><div>In this study we address two primary dimensions of collaborative data visualization and analysis as follows: [1] we detail the implementation of a novel co-located VR hardware and software system, [2] we conduct a formal user experience study of the novel system using the NASA Task Load Index (Hart, 1986) and introduce the Modified User Experience Inventory, a new user study inventory based upon the Unified User Experience Inventory, (Tcha-Tokey, Christmann, Loup-Escande, Richir, 2016) to empirically observe the dependent measures of Workload, Presence, Engagement, Consequence, and Immersion. A total of 77 participants volunteered to join a demonstration of this technology at Purdue University. In groups ranging from two to four, participants shared a co-located virtual environment built to visualize point cloud measurements of exploded supernovae. This study is not experimental but observational. We found there to be moderately high levels of user experience and moderate levels of workload demand in our results. We describe the implementation of the software platform and present user reactions to the technology that was created. These are described in detail within this manuscript.</div> Software Engineering Computer Software Computer Graphics Simulation and Modelling Virtual Reality and Related Simulation Mobile Technologies Networking and Communications Computer-Human Interaction Collaborative Virtual Reality Virtual Reality Collaborative Virtual Reality Networking Networked VR Mulitplayer Multiplayer VR Data Visualization Data Exploration Head Mounted Display Cyberspace Augmented Reality Emerging Technologies Consumer Devices Virtual Environment Virtual Aesthetics Collaborative VR Simulation Training Simulation and Training Colocated Colocated Virtual Environment Immersive Media Immersive Technology Collaborative Tools Educational Virtual Environment Point Cloud Representations Isosurface Representations Mesh Smoothng Supernova Supernovae Supernova Remnant Modeling Astronomy and Astrophysics Cassiopeia N132D E0102 Crab Nebula CAVE CAVE Theater Mobile VR Virtual Classrooms STEM Workload Workload Assessment Tool Presence Engagement Immersion Experience Consequence Simulator sickness Simulator Sickness Questionnaire NASA TLX NASA Task Load Index Unified User Experience Quesionnaire Modified User Experience Questionnaire Oculus Oculus Go Oculus Quest Novel Solutions Optitrack Motive Motion Capture Mocap User Experience Unity3D Game Engine Lidgren Room Scale VR Hall Scale VR Co-location Colocation Virtual Training Collaborative Virtual Environments Shared Virtual Environments Collaboration Whiteboard Mobile Virtual Reality VR HMD LAN UX CSCL UXQ TLX AR VE CVE 3D UI EVE
