Best of Both Worlds: Merging 360˚ Image Capture with 3D Reconstructed Environments for Improved Immersion in Virtual Reality

With the recent proliferation of high-quality 360° photos and video, consumers of virtual reality (VR) media have come to expect photorealistic immersive content. Most 360° VR content, however, is captured with monoscopic camera rigs and inherently fails to provide users with a sense of 3D depth and 6 degree-of-freedom (DOF) mobility. As a result, the medium is significantly limited in its immersive quality. This thesis aims to demonstrate how content creators can further bridge the gap between 360° content and fully immersive real-world VR simulations. We attempt to design a method that combines monoscopic 360° image capture with 3D reconstruction -- taking advantage of the best qualities of both technologies while only using consumer-grade equipment. By mapping the texture from panoramic 360° images to the 3D geometry of a scene, this system significantly improves the photo-realism of 3D reconstructed spaces at specific points of interest in a virtual environment. The technical hurdles faced during the course of this research work, and areas of further work needed to perfect the system, are discussed in detail. Once perfected, a user of the system should be able to simultaneously appreciate visual detail in 360-degrees while experiencing full mobility, i.e., to move around within the immersed scene.Bachelor of Art

Pixelated Domes: Cinematic Code Changes through a Frank Lloyd Wright Lens

Panoramic 360-degree documentary videos continue to saturate the visual landscape. As practitioners\u27 experiment with a new genre, understanding meaning and making awaits the academic and marketplace landscape. The new media journey of 360-degree documentary storytelling is ripe for media archaeologist to explore. New media scholar Lev Manovich (2016) believes we are witnessing the new emergence of a cultural metalanguage, something that will be at least as significant as the printed word and cinema before it (p. 49) Considering the meta- development of this new media genre, my dissertation seeks to discuss the historical roots of the panoramic image, define 360-degree Cinematic Virtual Reality (CVR) documentary video, establish production distinctions between 360-degree CVR and two-dimensional documentary video, and reveal the spatial cognitive abilities of 360-degree documentary video. The purpose of this dissertation study is to establish a media archaeological context of the 360-degree image and reveals the development of new cinematic code variations between 360 CVR modalities and two-dimensional documentary form. The theoretical framework developed within this study will inform current and future 360-degree documentary narrative engagement practices. Secondly, this project seeks to evaluate spatial cognition levels when viewing a Frank Lloyd Wright walking tour through 360 CVR modalities and examine the influence this has on narrative engagement comparative to traditional two-dimensional documentary form

3D Multimodal Interaction with Physically-based Virtual Environments

The virtual has become a huge field of exploration for researchers: it could assist the surgeon, help the prototyping of industrial objects, simulate natural phenomena, be a fantastic time machine or entertain users through games or movies. Far beyond the only visual rendering of the virtual environment, the Virtual Reality aims at -literally- immersing the user in the virtual world. VR technologies simulate digital environments with which users can interact and, as a result, perceive through different modalities the effects of their actions in real time. The challenges are huge: the user's motions need to be perceived and to have an immediate impact on the virtual world by modifying the objects in real-time. In addition, the targeted immersion of the user is not only visual: auditory or haptic feedback needs to be taken into account, merging all the sensory modalities of the user into a multimodal answer. The global objective of my research activities is to improve 3D interaction with complex virtual environments by proposing novel approaches for physically-based and multimodal interaction. I have laid the foundations of my work on designing the interactions with complex virtual worlds, referring to a higher demand in the characteristics of the virtual environments. My research could be described within three main research axes inherent to the 3D interaction loop: (1) the physically-based modeling of the virtual world to take into account the complexity of the virtual object behavior, their topology modifications as well as their interactions, (2) the multimodal feedback for combining the sensory modalities into a global answer from the virtual world to the user and (3) the design of body-based 3D interaction techniques and devices for establishing the interfaces between the user and the virtual world. All these contributions could be gathered in a general framework within the 3D interaction loop. By improving all the components of this framework, I aim at proposing approaches that could be used in future virtual reality applications but also more generally in other areas such as medical simulation, gesture training, robotics, virtual prototyping for the industry or web contents.Le virtuel est devenu un vaste champ d'exploration pour la recherche et offre de nos jours de nombreuses possibilités : assister le chirurgien, réaliser des prototypes de pièces industrielles, simuler des phénomènes naturels, remonter dans le temps ou proposer des applications ludiques aux utilisateurs au travers de jeux ou de films. Bien plus que le rendu purement visuel d'environnement virtuel, la réalité virtuelle aspire à -littéralement- immerger l'utilisateur dans le monde virtuel. L'utilisateur peut ainsi interagir avec le contenu numérique et percevoir les effets de ses actions au travers de différents retours sensoriels. Permettre une véritable immersion de l'utilisateur dans des environnements virtuels de plus en plus complexes confronte la recherche en réalité virtuelle à des défis importants: les gestes de l'utilisateur doivent être capturés puis directement transmis au monde virtuel afin de le modifier en temps-réel. Les retours sensoriels ne sont pas uniquement visuels mais doivent être combinés avec les retours auditifs ou haptiques dans une réponse globale multimodale. L'objectif principal de mes activités de recherche consiste à améliorer l'interaction 3D avec des environnements virtuels complexes en proposant de nouvelles approches utilisant la simulation physique et exploitant au mieux les différentes modalités sensorielles. Dans mes travaux, je m'intéresse tout particulièrement à concevoir des interactions avec des mondes virtuels complexes. Mon approche peut être décrite au travers de trois axes principaux de recherche: (1) la modélisation dans les mondes virtuels d'environnements physiques plausibles où les objets réagissent de manière naturelle, même lorsque leur topologie est modifiée ou lorsqu'ils sont en interaction avec d'autres objets, (2) la mise en place de retours sensoriels multimodaux vers l'utilisateur intégrant des composantes visuelles, haptiques et/ou sonores, (3) la prise en compte de l'interaction physique de l'utilisateur avec le monde virtuel dans toute sa richesse : mouvements de la tête, des deux mains, des doigts, des jambes, voire de tout le corps, en concevant de nouveaux dispositifs ou de nouvelles techniques d'interactions 3D. Les différentes contributions que j'ai proposées dans chacun de ces trois axes peuvent être regroupées au sein d'un cadre plus général englobant toute la boucle d'interaction 3D avec les environnements virtuels. Elles ouvrent des perspectives pour de futures applications en réalité virtuelle mais également plus généralement dans d'autres domaines tels que la simulation médicale, l'apprentissage de gestes, la robotique, le prototypage virtuel pour l'industrie ou bien les contenus web

Expert evaluation of aspects related to virtual reality systems and suggestions for future studies

Abstract. In this bachelor’s thesis, we review existing quantitative and qualitative research on virtual reality systems. We then present suggestions for performing a future study to combine the objective and subjective measurements of virtual reality experience. Additionally, we adapted an existing heuristics-based expert evaluation method to suit evaluating virtual reality systems. Using our method, we performed the expert evaluation on a selection of five modern consumer virtual reality systems to understand the connections between the subjective experience and the physical variables related to the virtual reality system. From this evaluation, we present findings that are used to construct discussion and to draw conclusions on these said connections. We found the most prominent conclusion to be that the experience of virtual reality is highly subjective and dependent on the content being viewed in virtual reality. Additionally, we concluded that some of the most important aspects in need of improvement are display resolution, lens design, user ergonomics, and lack of wirelessness. Finally, we state that two optimization problems are present; the first one being the optimization required to design a virtual reality system and the second one being the act of choosing a system to match a consumer’s preferred content.Tiivistelmä. Tässä kandidaatin tutkielmassa käymme läpi aiempaa kvantitatiivista ja kvalitatiivista tutkimusta virtuaalitodellisuusjärjestelmistä. Esitämme myös ehdotuksia myöhempää tutkimusta varten virtuaalitodellisuuteen liittyvien objektiivisten ja subjektiivisten mittausten yhdistämiseksi. Tämän lisäksi adaptoimme aiemman heuristiikkapohjaisen asiantuntija-arvioinnin sopimaan virtuaalitodellisuusjärjestelmien arviointiin. Käyttäen metodiamme toteutimme asiantuntija-arvioinnin viidellä modernilla kuluttajakäyttöön tarkoitetulla virtuaalitodellisuusjärjestelmällä ymmärtääksemme yhteyksiä subjektiivisen kokemuksen ja niiden fysikaalisten muuttujien välillä, jotka liittyvät virtuaalitodellisuusjärjestelmiin. Esitämme tämän asiantuntija-arvioinnin löydöksiä, ja luomme niiden avulla keskustelua, jonka avulla teemme mainittuihin yhteyksiin liittyviä johtopäätöksiä. Tärkein johtopäätöksemme oli se, että virtuaalitodellisuuden kokemus on erittäin subjektiivinen ja riippuvainen siitä sisällöstä, jota virtuaalitodellisuudessa koetaan. Aiemman lisäksi toteamme, että merkittävimpiä kehitystä kaipaavia osa-alueita ovat näytön resoluutio, linssien suunnittelu, käyttäjäergonomia ja langattomuuden puute. Viimeisenä totesimme, että virtuaalitodellisuusjärjestelmiin liittyy kaksi optimointiongelmaa; ensimmäinen liittyy järjestelmän suunnittelussa tapahtuvaan optimointiin, ja toinen liittyy sellaisen järjestelmän valitsemiseen, joka sopii kunkin kuluttajan suosimaan tarkoitukseen
