A 3d talking head for mobile devices based on unofficial ios webgl support

In this paper we present the implementation of a WebGL Talking Head for iOS mobile devices (Apple iPhone and iPad). It works on standard MPEG-4 Facial Animation Parameters (FAPs) and speaks with the Italian version of FESTIVAL TTS. It is totally based on true real human data. The 3D kinematics information are used to create lips articulatory model and to drive directly the talking face, generating human facial movements. In the last year we developed the WebGL version of the avatar. WebGL, which is 3D graphic for the web, is currently supported in the major web browsers for desktop computers. No official support has been given for mobile device main platforms yet, although the Firefox beta version enables it on android phones. Starting from iOS 5 WebGL is enabled only for the advertisement library class (which is intended for placing ad-banners in applications). We have been able to use this feature to visualize and animate our WebGL talking head

Playing with Virtual Reality: Early Adopters of Commercial Immersive Technology

This dissertation examines early adopters of mass-marketed Virtual Reality (VR), as well as other immersive technologies, and the playful processes by which they incorporate the devices into their lives within New York City. Starting in 2016, relatively inexpensive head-mounted displays (HMDs) began to be manufactured and distributed by leaders in the game and information technology industries. However, even before these releases, developers and content creators were testing the devices through “development kits.” These de facto early adopters, who are distinctly commercially-oriented, acted as a launching point for the dissertation to scrutinize how, why and in what ways digital technologies spread to the wider public. Taking a multimethod approach that combines semi-structured interviews, two years of participant observation, media discourse analysis and autoethnography, the dissertation details a moment in the diffusion of an innovation and how publicity, social forces and industry influence adoption. This includes studying the media ecosystem which promotes and sustains VR, the role of New York City in framing opportunities and barriers for new users, and a description of meetups as important communities where devotees congregate. With Game Studies as a backdrop for analysis, the dissertation posits that the blurry relationship between labor and play held by most enthusiasts sustains the process of VR adoption. Their “playbor” colors not only the rhetoric and the focus of meetups, but also the activities, designs, and, most importantly, the financial and personal expenditures they put forth. Ultimately, play shapes the system of production by which adopters of commercial VR are introduced to the technology and, eventually, weave it into their lives. Situating play at the center of this system highlights that the assimilation of digital media is in part an embodied and irrational experience. It also suggests new models by which future innovations will spread to the public

EVA London 2022: Electronic Visualisation and the Arts

The Electronic Visualisation and the Arts London 2022 Conference (EVA London 2022) is co-sponsored by the Computer Arts Society (CAS) and BCS, the Chartered Institute for IT, of which the CAS is a Specialist Group. Of course, this has been a difficult time for all conferences, with the Covid-19 pandemic. For the first time since 2019, the EVA London 2022 Conference is a physical conference. It is also an online conference, as it was in the previous two years. We continue with publishing the proceedings, both online, with open access via ScienceOpen, and also in our traditional printed form, for the second year in full colour. Over recent decades, the EVA London Conference on Electronic Visualisation and the Arts has established itself as one of the United Kingdom’s most innovative and interdisciplinary conferences. It brings together a wide range of research domains to celebrate a diverse set of interests, with a specialised focus on visualisation. The long and short papers in this volume cover varied topics concerning the arts, visualisations, and IT, including 3D graphics, animation, artificial intelligence, creativity, culture, design, digital art, ethics, heritage, literature, museums, music, philosophy, politics, publishing, social media, and virtual reality, as well as other related interdisciplinary areas. The EVA London 2022 proceedings presents a wide spectrum of papers, demonstrations, Research Workshop contributions, other workshops, and for the seventh year, the EVA London Symposium, in the form of an opening morning session, with three invited contributors. The conference includes a number of other associated evening events including ones organised by the Computer Arts Society, Art in Flux, and EVA International. As in previous years, there are Research Workshop contributions in this volume, aimed at encouraging participation by postgraduate students and early-career artists, accepted either through the peer-review process or directly by the Research Workshop chair. The Research Workshop contributors are offered bursaries to aid participation. In particular, EVA London liaises with Art in Flux, a London-based group of digital artists. The EVA London 2022 proceedings includes long papers and short “poster” papers from international researchers inside and outside academia, from graduate artists, PhD students, industry professionals, established scholars, and senior researchers, who value EVA London for its interdisciplinary community. The conference also features keynote talks. A special feature this year is support for Ukrainian culture after its invasion earlier in the year. This publication has resulted from a selective peer review process, fitting as many excellent submissions as possible into the proceedings. This year, submission numbers were lower than previous years, mostly likely due to the pandemic and a new requirement to submit drafts of long papers for review as well as abstracts. It is still pleasing to have so many good proposals from which to select the papers that have been included. EVA London is part of a larger network of EVA international conferences. EVA events have been held in Athens, Beijing, Berlin, Brussels, California, Cambridge (both UK and USA), Canberra, Copenhagen, Dallas, Delhi, Edinburgh, Florence, Gifu (Japan), Glasgow, Harvard, Jerusalem, Kiev, Laval, London, Madrid, Montreal, Moscow, New York, Paris, Prague, St Petersburg, Thessaloniki, and Warsaw. Further venues for EVA conferences are very much encouraged by the EVA community. As noted earlier, this volume is a record of accepted submissions to EVA London 2022. Associated online presentations are in general recorded and made available online after the conference

Online opera: an applied collision of opera and web creativity

This practice-based research explores the collision of opera and web creativity through the development and evaluation of a new 'online opera' called "The Village" (2015). Contrasting existing offerings that position the web as a means of disseminating more familiar representations of opera, "The Village" draws on concepts of participatory culture, digital storytelling and co-creativity to advance a culturally novel apprehension of online opera that treats the web as a unique creative space. This interpretation is intrinsically digital, unable to be realised through conventional forms of theatrical presentation, and transformative in its approach to the core elements of opera. "The Village" in additional serves as a vehicle to investigate how the phenomenon of 'liveness' - that is, a feeling of 'now-ness' experienced in live performance - may be reimagined in the context of an entirely mediated opera. A range of theoretical perspectives are drawn on to establish a set of liveness devices that attempt to evoke in visitors to "The Village" a sense of contemporaneity and shared experience. These include temporal alignment between virtual and real-world events and the facilitation of social interaction through a narrative mechanism called the 'Digital Chorus', amongst others. Evaluative activities critique the effectiveness of such devices, and offer means in which they may be modified to better construct 'the live'
