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.
