A Metaverse: Taxonomy, Components, Applications and Open Challenges Flashcards
(Article :A Metaverse: Taxonomy, Components, Applications and Open Challenges)
What are the Ddifferences between the novel Metaverse and the earlier Metaverse?
o rapid development of deep learning dramatically improves the accuracy of vision and
language recognition, and the development of generative models enables a more immersive
environment and natural movement
o processing time and complexity were reduced
o Metaverse previously served based on PC access and had low consistency due to time and
space constraints, but now it is possible to easily access the Metaverse anytime, anywhere o virtuous cycle ecosystem in which the inflow and income of producers increase as users and usage time increase while serving various contents, and thus sales of digital advertisements
increase#
o the current Metaverse differs from the previous one because program coding can be done in
the Metaverse world, and it is more bonded to real life with virtual currency

What are the Differences between Metaverse and AR/VR?
- VR-related studies focus on a physical approach and rendering, Metaverse has a strong aspect as a service with more sustainable content and social meaning
o Metaverse does not necessarily use AR and VR technologies
o Metaverse has a scalable environment that can accommodate many people is essential to
reinforce social meaning

What are required three components in the large-scale Metaverse implementation ?
- hardware improvements
o the development of the recognition and expression model that leverages the parallelism of
the hardware
o the availability of content that people immerse in and participate in

What is Metaverse?
- three-dimensional virtual world where avatars engage in political, economic, social, and
cultural activities - various definitions and similar concepts exist
e.g.,divisionintolife-logging,mirrorworld,augmentedreality,andthevirtualworld according to whether the implemented space is reality- oriented or virtual-centred, and whether the implemented information is external environment information- centred and individual-centred
(Article :A Metaverse: Taxonomy, Components, Applications and Open Challenges)
What is Avatar?
Avatar
o alter ego that has descended to the earth, and it started from the concept that a fundamental
being changed its form to human
o performs a social role suitable for a job and persona in Metaverse
o digital twin is a virtual model for predicting behaviour and is used to create real-object-like
agents in the virtual world and predict outcomes in advance through simulations of situations
that might occur in real life
o Digital Me is a symbolic expression of ego in a digital world that is different from the actual
self
(Article :A Metaverse: Taxonomy, Components, Applications and Open Challenges)
What is Extended Reality (XR)?
Extended Reality (XR)
o XR is related to VR (virtual reality), AR (augmented reality), and MR (mixed reality
o VR provides an experience as if you were in a specific place without physical limitations,
helping you learn about the ideas you can get from experiencing different places
o AR is a method of superimposing virtual objects on real space from a first-person perspective o MR is the concept of creating virtual objects that allow users to interact with the 3D
environment in the immersion of the virtual environment of VR and the overlay of virtual
content in AR
o XR is an extended reality, which is terms used to include VR, AR, and MR. XR is used for virtual
commerce or v-commerce to create computer-mediated indirect experiences

Metaverse Influence for User and Society: What is the Sentiment and Social Influence?
Sentiment and Social Influence
o People can lead a stable cyber life in the Metaverse because they can distinguish between real-life and virtual life
o social impact depends on the ecosystem, it is important to consider many aspects of social impact, including potential exacerbation of social inequities, computation demands, economics, legality, and ethics
o possible to use infinite resources that can be created indefinitely online rather than a deduction compensation from limited resources in the real-life world
(Article :A Metaverse: Taxonomy, Components, Applications and Open Challenges)
Metaverse Influence for User and Society: What is the User Participation and Benefit?
User Participation and Benefit
o less limited by time and space and can exist in multiple places through avatars, so the
communication style is changed from 1: N broadcasting to 1:1 interaction
o most effective in places like Africa where experiential education is difficult
o High-contrast vision, long-distance vision, and volume augmentation for people with visual
difficulties enable people with disabilities to live the same lives as ordinary people in
Metaverse
o Mask effects (i.e., hide shapes, colours, and races) are also noteworthy, providing a better-
than-realistic user engagement experience
o it is essential to provide fashion, games, and events on a regular and long-term basis
o it is possible to induce and increase user participation by providing a third person view rather
than a first-person spectator mode
(Article :A Metaverse: Taxonomy, Components, Applications and Open Challenges)
Metaverse Influence for User and Society: What are More Applications?
More Applications
o Consider interpretability, security, privacy, societal function, and ethics o Metaverse makes living easier
o Metaverse applications reduce physical object and space
(Article :A Metaverse: Taxonomy, Components, Applications and Open Challenges)
Metaverse Limitation: What is meant by Sustainability?
Sustainability
o when the number of users accessing decreases, the world cannot be maintained
o in order to maintain continuity, a connection relationship must be maintained continuously in
a relatively low-spec mobile device that can always be accessed
o storing all experiences in memory storage has limitations in utilization and capacity, so
memory research on effectively finding and reusing important episodes is needed
o latecomer platforms should consider import/export methods that bring the existing user
experience and provide continual usability
(Article :A Metaverse: Taxonomy, Components, Applications and Open Challenges)
Metaverse Limitation: What is meant by Hardware and Software Limitations?
Hardware and Software Limitations
o some sensations are better felt in real life
o as the program becomes more sophisticated, it faces the limit of sophistication in a complex
application
o it is necessary to study more complex persona modelling in consideration of the situation
o NPCs in the role of residents of the Metaverse must be able to cope with various unexpected
situations because the allowable range of scenarios is wide
(Article :A Metaverse: Taxonomy, Components, Applications and Open Challenges)
Metaverse Limitation: What is meant by Development Huddle?
Development Huddle
o there is a lot of work to study for individuals to start development without experience
o not enough information for practical details to make complex and realistic implementations o a collaborative system for an individual developer is important to co-develop without
designing the entire system
o necessary for the developer community to separate threads based on well-organized
taxonomy and maintain a group of experts who lead in each technical domain
