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 recent work titled “Towards Understanding Player Behavior in Blockchain Games: A Case Study of Aavegotchi” is accepted by the 17th International Conference on the Foundations of Digital Games (FDG 2022). Blockchain games introduces unique gameplay and incentive mechanisms by allowing players to be rewarded with in-game assets or tokens through financial activities. In practice, […]

Our paper “Economic Analysis of Decentralized Exchange Market with Transaction Fee Mining” received the Best Paper Award from ACM BSCI’22!

2022-05-312023-07-21 admin

In this paper, we establish the DEX market with transaction fee mining and formulate our model based on the Hotelling model. Besides, we propose a two-stage game to formulate the interaction between DEXs and users and derive the equilibriums under different conditions of two parameters: the transaction cost difference and users’ stickiness. We show that though the service provider with a lower transaction cost can win the market, users’ stickiness can offset the market advantage. Thus, incentivizing users with transaction fee mining has become a crucial strategy in the duopoly competition.
