Our Work “MetaCast: A Self-Driven Metaverse Announcer Architecture Based on Quality of Experience Evaluation Model” Is Accepted By ACM MM’ 23

2023-09-172023-09-17 admin

We propose a three-stage architecture for metaverse announcers, which is designed to identify events, position cameras, and blend between shots. Based on the architecture, we introduce a Metaverse Announcer User Experience (MAUE) model to identify the factors affecting the users’ Quality of Experience (QoE) from a human-centered perspective. In addition, we implement MetaCast, a practical self-driven metaverse announcer in a university campus metaverse prototype, to conduct user studies for MAUE model. The experimental results have effectively achieved satisfactory announcer settings that align with the preferences of most users, encompassing parameters such as video transition rate, repetition rate, importance threshold value, and image composition.

Our paper on Blockchain-Based Carbon Market Analysis Accepted by IEEE Wireless Communications Magazine

2023-07-212023-07-27 admin

To understand the role of blockchain in sustainability, we propose a three-tier structure based on the lifecycle of natural resources, encapsulating four utilities of blockchain: recording and tracking, wide verification, value trading, and concept disseminating. Based on this, we conduct a case study on Nori, a carbon credit market running on blockchain. Nori leverages the characteristics of blockchain, including public and immutable records, widespread verification achieved through smart contracts, and value creation through token and NFT transactions, to address issues in traditional carbon emission markets.

Our work “Altruistic and Profit-oriented: Making Sense of Roles in Web3 Community from Airdrop Perspective” is accepted by ACM CHI’23

Many decentralized applications (DApps) issue airdrops to early supporters for their contributions. However, most eligible users are motivated by financial profit or preferential access to tokens with governance rights to obtain quick cash. In this paper, we take ParaSwap as a representative example, trying to evaluate the Web 3.0 community and the effectiveness of allocation principles through the analysis of eligible users’ behavior and token transaction network.

Our Work MetaCube Editor Accepted By IEEE Communications Magazine

2022-12-262023-01-04 admin

Our recent work MetaCube is accepted to be published in IEEE Communications Magazine. In this work, we propose 3D Crypto-dropout, which utilizes Web3 users’ information to generate unique fine-grained 3D models for metaverse. Web3 (also known as Web 3.0) metaverse is a blockchain-driven networked, decentralized, and open virtual world. The key feature of the Web3 […]

Our Work “Metaverse for Social Good : A University Campus Prototye” Has Been Accepted by ACM MM’21

2021-08-202023-08-17 admin

Our recent work “Metaverse for Social Good : A University Campus Prototye” has been accepted by the Brave New Ideas (BNI) track of 29th ACM International Conference on Multimedia (ACM MM 2021). In this paper, we propose a three-layer architecture for metaverse, including infrastructure, interaction, and ecosystem, and the key components in each layer are […]
