The primary topic of today's call was an overview of the Multimodal
Interaction Working Group's spec, InkML, a markup language for representing
ink traces.

question on the permission for the minutes

   debbie: to make minutes public?

   [general agreement]

   <ChrisL> these minutes will be public

InkML presentation

   debbie: We focus on inkk ml

   tomun: various scenario types--basically there are two
   ... mainly archival
   ... aimed at ink capture devices, tablet, pen
   ... so, capture ink and store it
   ... second scenario is streaming ink, chat, whiteboard, etc
   ... third is just the acknowledgement that these two primary might
   be combined somehow
   ... so looking at use cases ...
   ... streaming, among clients
   ... another is ink and smil
   ... capturing ink and voice, for instance and sync'd with smil to
   playback faithfully
   ... have a demo that turns these into power point
   ... then there's archive and retrieval
   ... stored in docs and used to store
   ... also supported search and analysis, as well as annotation of
   existing docs
   ... electronic form filing is an application of ink
   ... believe it's valuable for signature authentication
   ... then pen input and modality systems--language disambiguate
   ... so voice prompts may disambiguate ink

   sw: sometimes write with finger rather than pen, is also captured

   tomun: also use of gestures to control app, including multiple
   finger touch
   ... also multiple simultaneous user

   sw: main idea is a sequence of points default x-y representation

   tomun: intended for multiple devices from very low level hardware on
   up

   sw: capable to store additional info with each point, force, angle,
   etc
   ... that leads to various ways to group -- and recognize
   ... supports associating xml or text with any x-y point
   ... of course, different devices means different dimensions and
   picsels

   tomun: so, in office 2010 ...
   ... word, excel and powerpoint support ink
   ... now stored as w3c inkml
   ... simplest case is capture and render
   ... but also analyses during spare cycles
   ... analysis may resume after doc is saved and later retrieved
   ... reco for a variety of things, text area, area into paras, lines,
   words, etc., also math
   ... if i write ' the quick brown' and then circle it ...
   ... engine recognizes text and the circle as annotation of the text
   ... text recognition supports search, of course
   ... eventually, moving text will move its annotations as well

   sw: we have a skype add on supporting shared ink during conversation
   ... we have a skype add on supporting shared ink during conversation

   tomun: --showing example of signature use -- and its authentication
   ... also hifi rendering for zoom
   ... variable penforce is stored, so allows better fidelity and
   better forensic analysis
   ... and rich timestamping
   ... inkml stores what strokes when

   sw: uncompressed, inkml smaller than rasterized data
   ... high compression supported because of rich data

   tomun: --showing demo of inkml plus smil -- with mobile device
   ... photos of real world, ink annotated, plus voice annotation; all
   stored and time stamped
   ... have written a demo app that grabs these streams into animated
   powerpoint

   <kaz> (Tom leaves)

   sw: questions, anyone?

   debbie: can inkml cooperate with capture api from web apps?
   ... believe this api was for video, or perhaps photos

   <ChrisL> robin berjon could, if a question is sent to the list

   sw: we've had success with various apps behind various apis, so it's
   possible

   debbie: wonders about skype app in more detail

   sw: one supported collab backbone is skype's
   ... allows people on different devices to share a screen
   ... but also a recorded wav plus timestamps on audio and stream
   ... next step is to attach recognition to this
   ... personal interest to reco math
   ... because hand written math is so different from keyboarded math
   ... now using a more portable java plugin so can support more
   devices
   ... but do not adhere to TOS for iPhone, so not there

   debbie: likes the archiving

   sw: good point
   ... important to understand that archive and streaming aren't really
   disjoint because semantics are added as more analysis is done
   ... so can become more organized with more knowledge over time

   kaz: wonders about relation to xforms
   ... perhaps also passwd?

   sp: shouldn't be difficult
   ... xforms has ability to capture the data

status of InkML specification

   debbie: a word of where this is as a spec ...
   ... about to publish second last call
   ... interested in feedback from several groups

   <ChrisL> svg can review it certainly

   sw: html, svg, janina: wondering about a pf review

   debbie: perhaps could make handwriting accessible

   <ChrisL> AIDE Alternative Input Device Events

   <plh-home> plh: we're been trying to add support for AIDE in the
   WebApps group charter. we ran into formal objections that we're
   trying to resolve at the moment. probably some relation with InkML?

   debbie: so how to represent just a stroke?

   sw: so pen can be touching surface, or not, and we record pen
   trajectory
   ... then higher level reco engine interprets
   ... width, height, and orientation can also be recorded -- so
   major/minor axis, and rotation
   ... pressure
   ... also traces that overlap in time
   ... can have long gestures in time, e.g. squeeze
   ... traces can be packetized in time, so a continuation from
   previous

   debbie: any other questions?
   ... thinking of a 3-week review period

   <ChrisL> sounds ok to me, svg has a f2f next week. let me know when
   its published

   <ChrisL> thanks to all, interesting session

   debbie: thanks to stephen and tom

action items

   debbie: actions ...
   ... mine to be continued

   chris: mine can be closed

next meeting

   debbie: so next meeting, june 4, captioning

   nts

     [11]
http://www.w3.org/WAI/PF/HTML/wiki/Media_Accessibility_Requirements

   debbie: so media type for text/html in a later call?
   ... so media type for text/html in a later call?

   plh: so a new definition from html5
   ... so who's affected? xhtml1?

   sp: new def includes xh1?

   plh: believe so
   ... but deprecated

   sp: that's first step to disallow
   ... old xhtml group observed text/html delivered without
   problems--typical practice

   plh: perhaps yes, perhaps no ...
   ... any xhtml 1.1 providing media type?

   sp: a note that documents current practice, and which works, nothing
   normative
   ... also rdfa

   plh: related to issue 41 in html
   ... ok, thanks

   debbie: anything else for today?
