SESSION 10 - A metaverse: taxonomy, components, applications, and open challenges

Question 1

What are differences between the novel metaverse and the earlier metaverse?

Answer 1

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

Question 2

Whats the difference between metaverse and AR/VR?

Answer 2

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

Question 3

What are the three components that the large scale metaverse required?

Answer 3

o 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

Question 4

What is the metaverse?

Answer 4

o three-dimensional virtual world where avatars engage in political, economic, social, and
cultural activities
o 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

Question 5

What is extended reality? (XR)

Answer 5

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

Question 6

What are the benefits of the metaverse?

Answer 6

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
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

Question 7

What are the limitations of the metaverse?

Answer 7

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
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
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
