Action items identified

Comments

General

Peter
Is it OK to use the term Metaverse?
Erik
this was checked, and the term is not trademarked.
Peter
use of ‘metaverse’ before the term ‘media’ confuses the definition, possibly making it circular

Term ‘local’

Peter
The term is too broad, must be qualified.
Alice
the key aspect is ‘relevance’ but it is not easy to see this at first
Erik
OK, I will restructure the sentence to bring this to the front.

Term ‘digital representation’

Lei
this may be of physical objects as well as virtual objects. Is the term ‘avatar’ redundant?
Erik
Avatar is more specific and used as part of many service descriptions in the TR, we should keep it.
Daniel
‘media’ is too broad a term and must be clarified

Term ‘avatar’

It was initially written to be of a ‘person’ or ‘virtual object’, but ‘virtual object’ is too broad & clashes with digital representation and is somehow circular.

It was observed that an avatar is not always a person, it could be any interactive being (including a virtual entity provided by software, a pet, etc.)

Terms ‘mobile metaverse, mobile metaverse service’

Peter
the term mobile metaverse should be the basis and not derived from mobile metaverse service
Peter, Daniel
in what sense ‘mobile’. OK to differentiate from ‘metaverse’ but is this the right term?

Term ‘immersive’

It was observed that this term is subjective.

Term ‘pose’

Lei
shouldn’t we mention movement in the definition?
Yvette (?)
This term does not imply any movement
Alice
there is a much more detailed definition of XRPose from SA4, perhaps use this (26.928)

Relation between Sensing and Metaverse

Erik
I think there is a lot we can do to improve the clarity of the relationship between sensing and metaverse studies. In particular, the KPIs for sensing (uplink) in the metaverse TR may belong in the sensing study. I am taking care of my use cases, but this is a general issue.
Alice
I agree that further clarity would be good. It may not be easy to achieve. Note that in SA4 they already have defined sensing uplink performance requirements.
Erik
the scope of sensing seems to be under debate - is it only NR related? or is it anything having to do with sensing data communication that remains unclear in stage 1?
