Your email reminds me of a statement I wanted to make a week or so ago: 
Perhaps the first task of this group is to define what we mean by a Point of 

AR provides a set of use cases. There are other use domains, such as 
navigation and gazetteer, that also provide use cases. Further, use domains 
such as navigation and GeoINT have been using POIs for decades and we have 
much to learn and leverage from those communities.

AR should not be the only use case. Further, I think we need to be very 
careful not to have such a broad set of objectives, such as "a framework for 
AR on the web" that we cannot actually define a model and vocabulary for 

We also need to be cognizant of the POI related work done in other standards 
communities, such as OMA, the IETF, ISO, the OGC, and so forth. This 
coordination aspect of the POI work also suggests to me the need for 
restriction of scope and not extension of scope. If I remember, Gary also 
suggested a relatively narrow scope of work to insure definition of a 
recommendation that has broad implementation appeal.

Subject: RE: WG Objectives - A Personal Take

Hi everyone,

As I was presented on my position paper[1] from AR on the Web workshop,
I'd like to develop the basic standards for AR interoperability using Web 

As you know well, Interoperability issue is one of major challenges faced by 
the small
but fast-growing industry of Augmented Reality. Currently, many people 
cannot share the
augmented information between different AR browsers and AR service 

I think the Scope of POI WG may not limited on just the POI related issues.
I think we need to deal with various issues for interoperable AR services 
and AR on the Web,
in initial stage of WG.

In this POI WG, my major question is starting from
"Does AR services must need a Dedicated AR browser ?",
"Is it impossible to use General Web User Agent(web browser) for AR browsing 

Here's my questions what I'd like to try to find answer from POI WG:
 1) How can we make a framework for AR on the Web
 2) How can we make a representation model for Augmented Data (like as POI)
 3) Just PoI(Point of Interest) ? Do we need to extend from PoI to 
CoI(Context of Interest) ?
 4) Do we need a scheme for identification of physical object/POI ?
 5) What we consider from other W3C activities and how to cooperate with 
 6) How can we make the OneWeb and AR services on the OneWeb  ?
 7) What we need to develop ...

Best Regards,

--- Jonathan Jeon
