PolyU Seminar on the Metaverse: AI-Powered Universe of Persistent Digital Twins

The PolyU Distinguished Seminar Series on DSAI (both online and offline) named “The Metaverse: AI-Powered Universe of Persistent Digital Twins” was organized by COMP Depart., PolyU on 10th May 2024. A digital twin is a digital replication of a living or non-living physical entity. A Metaverse encompasses an interconnected realm of persistent Digital Twins. Prof. Abdulmotaleb El Saddik was the guest speaker (Distinguished Professor, Mohamed Bin Zayed University of AI). 


Firstly, Prof. Saddik mentioned the opportunity and challenges of different technologies including Digit Twin and Web 3.0, etc. In the past, there are less publication related to metaverse until 2022-2023 that spike goes beyond thousands of publications.


The metaverse can be defined as a digital environment that uses extended reality (AR/VR, Haptics), AI, IoT, Cloud Computing, NFTs, Physic/game engines and blockchain, along with concepts from social media, to create spaces for rich user interaction mimicking the real world. Prof. Saddik said “The metaverse is the universe of Persistent Digital Twins.” Then the timeline of the development of metaverse from 1991 to 2022 was described.


And then he mentioned the Mixed Reality (MR) that MR is the merging of real world and virtual worlds to produce a new environment where physical and digital objects can co-exist and interact. The working principle of head-Mounted display VR device was discussed.


After that Prof. Saddik introduced the evolution of the Web from 1.0 to 3.0. And Non-fungible token (NFT) usage in a VR-based metaverse was mentioned.


Prof. Saddik then introduced Digital Twin and Metaverse through his paper named “A digital twin is a digital replica of a living or non-living physical entity” (2018).


Finally, he stated the metaverse is the universe of Persistent Digital Twins through different technologies including cybersecurity, blockchain, big data, AI and multi-media interaction. 


Some cases were demonstrated such as bridge from reality and virtue using Robotic Arms.


Lastly, Prof. Saddik briefed some potential use in the Metaverse, technology research challenges and societal research challenges.


At the end, he showed the prediction timeline that AR/VR would become mainstream at 2030.
