Updates

   McCool: had joint meeting with APA WG
   ... also PBG
   ... got various use case proposals

   Lagally: concrete contributions expected?

   McCool: yes, e.g., from Daihei Shiohama

   Lagally: great

   Jennifer: planning to work on geospatial use cases but still
   need to work

   McCool: no problem
   ... note that we're planning to have joint discussion with the
   Spatial Data IG at some point

   Jennifer: ok

   Lagally: would make sense to add your topic for the meeting in
   2 weeks?

   Jennifer: ok

   [12]Sep-17

     [12] https://www.w3.org/2020/09/17-wot-uc-minuts.html

   Kaz: the point is that there were a bunch of possible use cases
   from the Singapore Geospatial Week but we don't need to collect
   all of them

   Lagally: wondering about the style of McCool's comment

   Kaz: will change the style from "irc" to "phone"

   Lagally: ok

   McCool: that is the comment I directly typed into the IRC

   Lagally: ok
   ... let's keep it asis then

   Kaz: on the other hand, second comment by McCool inserted later
   is the one I myself added since it was missing, so will fix the
   style

   Lagally: ok

vF2F discussion - remaining topics

   <inserted> scribenick: mlagally

   Kaz: rob, can you please present your slides and use case.md?

   Rob: yes
   ... Key use cases: Golden tutorial and virtual guide
   ... golden tutorial is using AR, proof of action, capture
   format for AR debug to allow sync of data
   ... recording video and feeds input data to AI to produce an
   overlapped image
   ... this not a replacement for AR markup language
   ... combination of recorded video and recorded sensor data to
   live AR system
   ... virtual guide
   ... audio track provides guidance, provides triggers for
   virtual guides
   ... sync with map
   ... this could also be used for medical use cases
   ... camera with AR shows bones or areas where to give an
   injection
   ... an AR camera could be pointed to a real world object,
   guidance could be given how to use that object
   ... i.e. control the Web of Things thing
   ... can also be synchronized with an annotated map
   ... AR overlay on the video shows a model and some additional
   linformation

   McCool: this seems to require geolocation, slam?
   ... slam may require significant computation, edge computing
   use case.

   <inserted> kaz: yeah, so Rob has created a use case MD on
   vertical aspect and myself created another use case MD from
   horizontal viewpoint including geolocation collaboration

   Lagally: are you using standard for geolocation?

   Rob: we are defining WebVMT is JSON based but not pure JSON

   <kaz> [14]Rob's proposed breakout session

     [14] https://www.w3.org/wiki/TPAC/2020/SessionIdeas#Video_Metadata_For_Moving_Objects_.26_Sensors_On_The_Web_.28WebVMT.29

   Rob: allows encapsulating data, see GeoJSON example

   McCool: you are having streaming data in chunks, similar to
   events that was done by Mozilla
   ... is it a protocol for sending events as JSON chunks?

   Rob: yes
   ... how do you do duration?

   McCool: need to consider, not handling it currently
   ... can events be queued out of order?

   Rob: why do you need that?

   mccool, some serialisation may change the order

   Rob: events typically are in order, need to think about it

   Kaz: I invited Rob to explain how synchronisation in media
   happens, this can be very useful for WoT
   ... 3D model could also be interesting

   Rob: absolutely

   <kaz> [15]PR 62 - Rob's use case description

     [15] https://github.com/w3c/wot-usecases/pull/62

   <kaz> [16]PR 61 - Kaz's use case description

     [16] https://github.com/w3c/wot-usecases/pull/61

   <inserted> scribenick: kaz

   Kaz: Rob's use case is more application specific
   ... my use case is more horizontal UI platform

   Lagally: wondering about how to deal with realtime video
   streams. don't want to look into the details of video codecs

   Kaz: related to WN discussion too
   ... possibly Web Transport could be considered
   ... would refine my use case description
   ... also will talk with Rob about how to proceed
   ... maybe we can compile those two PRs
   ... or should continue to improve both the PRs separately

Accessibility use cases

   McCool: bunch of discussion during the joint meeting with APA
   ... captured issues on the repo

   [17]Issue 64

     [17] https://github.com/w3c/wot-usecases/issues/64

   McCool: would be useful to automotive environment too
   ... planning to have a followup meeting in Dec
   ... during the PlugFest call on Dep-9

   Lagally: ok
   ... btw, what do you mean by "Publishing, including recipes"?

   McCool: related to the use cases discussed during the PBG joint
   meeting

   Lagally: ok
   ... let's revisit this topic during the next UC call in 2 weeks
   ... tx a lot for your contributions, all!
