debbie: to make minutes public?
[general agreement]
<ChrisL> these minutes will be public
<ddahl> link to the slides from today -- http://www.w3.org/2002/mmi/2010/InkML/inkml.pdf
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
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
debbie: actions ...
... mine to be continued
chris: mine can be closed
debbie: so next meeting, june 4, captioning
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?
