This paper investigates the issue of identity construction in the emerging field of virtual clothing,using a set of digital artworks and a gaming community case study as research objects.Within the globally influential ACG(Animation,Comics,and Games)subculture,the digital“Avatar”has become the primary site for identity construction.Employing a mixed-methods approach that combines semiotic analysis,case studies,and exploratory metrics,this paper argues that virtual clothing,hairstyles,and aesthetic modifications are not mere representations but are practices imbued with performativity.The article uses a triangular theoretical framework composed of Roland Barthes’s fashion semiotics,Judith Butler’s theory of performativity,and Homi Bhabha’s concept of the“Third Space”as its main structure,supplemented by theories such as the“Proteus effect”,the“extended self”,and posthumanist thought,to provide a multi-dimensional interpretation of digital identity construction.The core proposition of this paper is that the“digital skin”,as a“performative interface”and“wearable capital”,not only constructs fluid,networked identities but also embodies social and economic value that operates within specific platform ecosystems.Through the analysis of visual grammar,in-game unlock mechanisms,and community discourse,this paper aims to reveal that the study of digital self-presentation has become a critical new frontier in the field of costume and culture studies,elucidating how identity is shaped,negotiated,and capitalized upon in the increasingly prevalent virtual environments of the 21st century. 展开更多

Recent advancements in the field have resulted in significant progress in achieving realistic head reconstruction and manipulation using neural radiance fields(NeRF).Despite these advances,capturing intricate facial details remains a persistent challenge.Moreover,casually captured input,involving both head poses and camera movements,introduces additional difficulties to existing methods of head avatar reconstruction.To address the challenge posed by video data captured with camera motion,we propose a novel method,AvatarWild,for reconstructing head avatars from monocular videos taken by consumer devices.Notably,our approach decouples the camera pose and head pose,allowing reconstructed avatars to be visualized with different poses and expressions from novel viewpoints.To enhance the visual quality of the reconstructed facial avatar,we introduce a view-dependent detail enhancement module designed to augment local facial details without compromising viewpoint consistency.Our method demonstrates superior performance compared to existing approaches,as evidenced by reconstruction and animation results on both multi-view and single-view datasets.Remarkably,our approach stands out by exclusively relying on video data captured by portable devices,such as smartphones.This not only underscores the practicality of our method but also extends its applicability to real-world scenarios where accessibility and ease of data capture are crucial. 展开更多

This study examines the emerging sustainability of metaverse ecosystems,which combine multiple virtual and augmented reality spaces where users interact.ESG criteria,which align with the Sustainable Development Goals and promote economic and financial sustainability,represent best practice standards for screening and backing viable projects.The research focus begins with the historical ESG scoring of metaverseprone BigTechs,demonstrating that they are more sustainable than traditional firms,as evidenced by the increase in the probability of payment between traditional clients and suppliers.Multilayer networks are then introduced,incorporating the scalability features of new nodes(avatars)and links that make the metaverse economically sustainable.The strongest ESG issues concern the social and governance component:access to the metaverse is hardened by authoritarian regimes,or ludopathies may be exacerbated by 3D dependence,detaching addicted surfers from the real world.Our findings show that integrating multilayer network theory with ESG metrics not only promotes economic sustainability but also supports governance innovations that drive digital inclusivity.By integrating ESG metrics with multilayer network theory,this research enhances economic sustainability and reveals governance innovations that foster digital inclusivity,strengthening the metaverse’s long-term viability. 展开更多

Avatars play a key role in how persons interact within virtual environments,acting as the digital selves.There are many types of avatars,each serving the purpose of representing users or others in these immersive spaces.However,the optimal approach for these avatars remains unclear.Although consumer applications often use cartoon-like ava-tars,this trend is not as common in work settings.To gain a better understanding of the kinds of avatars people prefer,three studies were conducted involving both screen-based and virtual reality setups,looking into how social settings might affect the way people choose their avatars.Personalized avatars were created for 91 participants,including 71 employees in the automotive field and 20 participants not affiliated with the company.The research shows that work-type situations influence the chosen avatar.At the same time,a correlation between the type of display medium used to display the avatar or the person’s personality and their avatar choice was not found.Based on the findings,recom-mendations are made for future avatar representations in work environments and implications and research questions derived that can guide future research. 展开更多

Avatars, as promising digital representations and service assistants of users in Metaverses, can enable drivers and passengers to immerse themselves in 3D virtual services and spaces of UAV-assisted vehicular Metaverses. However, avatar tasks include a multitude of human-to-avatar and avatar-to-avatar interactive applications, e.g., augmented reality navigation,which consumes intensive computing resources. It is inefficient and impractical for vehicles to process avatar tasks locally. Fortunately, migrating avatar tasks to the nearest roadside units(RSU)or unmanned aerial vehicles(UAV) for execution is a promising solution to decrease computation overhead and reduce task processing latency, while the high mobility of vehicles brings challenges for vehicles to independently perform avatar migration decisions depending on current and future vehicle status. To address these challenges, in this paper, we propose a novel avatar task migration system based on multi-agent deep reinforcement learning(MADRL) to execute immersive vehicular avatar tasks dynamically. Specifically, we first formulate the problem of avatar task migration from vehicles to RSUs/UAVs as a partially observable Markov decision process that can be solved by MADRL algorithms. We then design the multi-agent proximal policy optimization(MAPPO) approach as the MADRL algorithm for the avatar task migration problem. To overcome slow convergence resulting from the curse of dimensionality and non-stationary issues caused by shared parameters in MAPPO, we further propose a transformer-based MAPPO approach via sequential decision-making models for the efficient representation of relationships among agents. Finally, to motivate terrestrial or non-terrestrial edge servers(e.g., RSUs or UAVs) to share computation resources and ensure traceability of the sharing records, we apply smart contracts and blockchain technologies to achieve secure sharing management. Numerical results demonstrate that the proposed approach outperforms the MAPPO approach by around 2% and effectively reduces approximately 20% of the latency of avatar task execution in UAV-assisted vehicular Metaverses. 展开更多

Purpose:This research presents findings from a qualitative exploration of the reactions of adolescents(12-14 years old)to navigating an exergame with an avatar created from multiple scans of the player(referred to as a self-representational avatar).Methods:Post-gameplay interviews were conducted with adolescents following participation in a 20-min laboratory session(21.2±0.8 min,mean±SD)where the self-representational avatar was navigated through an exergame.Verbatim transcripts(n=40)were coded and analyzed by 2 independent coders using hybrid thematic analysis for this secondary data analysis.Codes were reviewed to identify themes representing adolescents’reactions.Results:Four themes emerged.Adolescents connected with their avatars and felt protective toward them,which influenced their actions in the exergame and contributed to their overall game enjoyment.Conclusion:Creating exergames navigated by a self-representational avatar was an enjoyable experience and influenced gameplay.Future research should explore the effect of this approach on gameplay frequency and intensity over time. 展开更多
