jgw: CAPTCHA revised FPWD is
published; some comments and issues logged
... Also our standing intent to possibly reorder
... and to further clarify we're focussed on a11y, not the
security/privacy implications
janina: Also some responses on the W3C blog
<jasonjgw> Janina notes comments received on the W3C blog post.
<jasonjgw> Responding to Scott, Janina notes taht the comments she has read do not seem to be raising major issues.
<jasonjgw> Jason concurs: comments raise detailed issues rather than fundamental concerns.
<jasonjgw> Judy notes additional issues, including the need to update the contributors' section - Michael has noted this already.
<jasonjgw> Janina notes the acknowledged desirability of a second phase of review.
jb: asks about timeline
<jasonjgw> Janina: supposing that we were to publish the Note by TPAC, early September would become the desired publication date of the next public working draft.
jgw: Will communicate reordering notions; perhaps a git branch
sh: can also review
jgw: asks about comment handling
js: Let's see what comes in
jgw: Definitely have comment via github issue ..
<jasonjgw> https://github.com/w3c/apa/issues/5
jgw: Notes ongoing discussion on
email
... papers referring to a contium of
reality/virtual-reality
... in context of visual display
... is the scene primarily generated, or captured real
world?
<sloandr> PDF version of the paper Jason is discussing is available here: http://etclab.mie.utoronto.ca/publication/1994/Milgram_Takemura_SPIE1994.pdf
jgw: this defines the
contium
... but also the display strategy is a differentiation
... noting image recognition may facilitate putting the
generated content atop the captured real world content
... RQTF question is having we covered enough to understand
a11y issues?
sh: think so
jgw: Will prioritize CAPTCHA for
now, but then come back to this
... Notes above cited is very often cited, so very worth
reading
<jasonjgw> Janina: Leonie Watson has proposed an accessibility of WebVR forum.
ds: Still working through a collection of papers that may also be relevant
<jasonjgw> David: continues to review augmented/virtual reality-related papers touching on accessibility, principally from ACM conferences.
ds: these will be use of ar/vr to solving a11y issues
jgw: Recalls these concerns were noted in an APA joint call on WebVR
ds: also readability of projected
vr interface content
... e.g. contrast
jgw: contemplates image analysis and consequent contrast calculation
ds: Notes lots of work 20 years ago, then very little, now again
<jasonjgw> Janina: is there a clear distinction between augmented and mixed reality?
js: asks whether there's a clear distinction between augmented and mixed
http://accessibility.linuxfoundation.org/a11yspecs/handlers/uuc1.html
<jasonjgw> Janina: notes a set of use cases developed a decade ago by the Linux Foundations' accessibility working group. Janina queries wehther it merits revisiting now, due to an upsurge of interest in better handling mathematical content.
<jasonjgw> Janina: there is a range of disciplines engaging domain-specific knoweldge that need to be handled appropriately by AT; if we had ways of making these domains accessible, we should explore mechanisms for making this possible.
<jasonjgw> Examples: mathematics, chemistry, music - all with different requriements (e.g., temporality in musical notation).
<jasonjgw> Janina: should we approach this from a more general perspective instead of solving each case separately?
<jasonjgw> Janina wishes to introduce this to APA and in relation to digital publishing as well as here.
<jasonjgw> Scott notes Web4All papers in 2016 that were relevant to the accessibility of STEM-based materials.
<jasonjgw> Janina notes that the intent underlying the Linux Foundation work was to be as general/global as appropriate.
<jasonjgw> David's understanding is that user agent support for specialized markup langauges such as MathML is a limiting influence.
<jasonjgw> Janina: the work undertaken a decade ago recognized that user agent support in these areas would always be problematic, and that general AT developers often would not be equipped with the specialized expertise to fine-tune the handling of these notations. The suggestion then was to provide a hand-off to a specialized tool for processing the domain-specific material.
<jasonjgw> Scott notes the challenges raised by specialized material (including technical content) in digital publications in relation to accessibility. He suggests finding out what work has been done in this field and investigating the architectural possibilities.
<jasonjgw> Judy notes previous efforts to address these issues in the W3C context and suggests further coordination.
<jasonjgw> Janina suggests we need a more general approach to these problems that extend beyond mathematics/STEM material.
<jasonjgw> Janina: knowledge domain-specific markup.
<jasonjgw> Janina notes work underway in music markup as another illustration.
<jasonjgw> Judy notes that mathematics/chemistry/music already constitutes a broad spectrum of problems.
<jasonjgw> Scott: notes that STEM is a good starting umbrella category from which the research review could be extended outward.
<jasonjgw> Janina: notes that packaging is the key here, and we need to develop packaging approaches that could apply to different domain-specific fields, so that someone with expert knowledge could make the AT work for each area, offering a plug-in appraoch that AT could then take advantage of.
