conformance section - ease of use kim to provide update on Mobile
Accessibility Task Force

<KimPatch> http://www.w3.org/WAI/GL/mobile-a11y-tf/wiki/Main_Page

kp: look at the wiki to know what MATF is doing
... working on resources
... source and date after everything, feedback requested
... ongoing discussion of responsive design.
... main task, currently, is #4 Techniques for WCAG
... thanks to Jan for BBC gap analysis
... MATF has a browser list, additions requested.

ja: UA wiki has new mobile page -

kp: UAAG mobile examples are different that WCAG. UAAG are user based
scenarios. WCAG a bit more technology based. difficult to correlate the two

js: UAAG examples are good use cases!
... are being used broadly for general accessibility.

Wayne and 1.4 comments

wd: minor things that are important
... specific values for spacing, needs to be specified that these
increments are added to the character (1.4.3 and 1.4.6)

<Jan> http://jspellman.github.io/UAAG/UAAG20/#gl-text-config

wd: CSS add the letter space value to the existing/default character
spacing provided by the UA

jr: our issue has to do with the prescriptive nature of the SC. if a UA
chooses different values to they fail.

wd: UA should do the whole range.
... character spacing is most effective at .1

jr: we need a range - min to max and a step range

wd: that would be the way to do it.
... not necessary to be so prescriptive

line 1.2 to 2

character .01 to .1, much beyond it slows the reader down.

ja: word spacing. Only in CSS.

gl: are there spacing requirements that could be made AAA because it is CSS
specific and we are trying to make technology agnostic

wd: word spacing could be moved to AAA
... CSS will change word spacing automatically when changing letter
spacing. No good research on word spacing.

gl: word spacing in CSS is independent of letter spacing, letter remains
intact with extra space between words.
... could move word spacing to 1.4.6 and removed from 1.4.3

<Jan> WD: Really useful Line spacing 1.2 TO 1.5

<Jan> WD: But top of the range should be 2.0

<Jan> WD: Character spacing MIN 0.02 to MAX 0.1

<Jan> WD: Word spacing can move to 1.4.6 AAA

gl: increased % or em

wd: should be EM
... browser implementation is varied
... should use EM units, common in typography

<Jan> WD: Character spacing concept is the amount to be added to the base
character width

<Jan> GL: character spacing..."Increased by amount..."

gl: 'letter spacing increased by X'

wd: some browser remove proportional spacing when user starts adjusting
letter spacing. but varied implementation not very important, because user
still benefits.
... font would still be ARIAL but more space between character, seems
almost fixed width.

gl: could keep word spacing at AA for technologies that support it and AAA
for others
... units, "time base character width (em)" suggested wording
... would eliminate typography jargon.

wd: many of the times in AAA need margins and padding to be less to make
reading easier.
... battle between large print and space on the screen. adjust font size,
then color, then spacing, repeat cycle. fit the most information in the
smallest space that user can still see
... there is one need group that would need column width and spacing issues
to be AA
... folks with 'tunnel vision' need the reduced spacing
... other group - vision loss (glaucoma) can only see in the middle
... need narrow columns, closer line spacing, etc

eh: want more info about word wrapping and narrow columns.

kp: this is true for mobile also. horizontal scrolling pops up and is
difficult for users

wd: will have research on horizontal scrolling and reading speed etc. by
mid summer

eh: does column width rate a higher value in the guidelines

<Jan> 1.8.9 Allow Viewport Resize: The user can resize viewports within
restrictions imposed by the platform, overriding any values specified by
the author. (Level AA)

wd: should be a higher value
... borders and text style of 1.4.5 should be AAA, margins should be AA

ja: problem in CSS there is no column width (except tables), in ms word you
have a feature to make 1-6 columns with word wrap and flow. not in css

<Jan_> 1.8.15 Ignore Absolute Layout Dimensions: The user can have the user
agent override author-specified absolute layout dimensions. (Level AA)

<Jan_> just adding some relevant SCs....

js: need to remember other technologies.

eh: need to capture this issue. is there a solution, do we need to track

wd: good responsive design (author controlled) should cover this.

<Jan_> 1.8.16 Linearize Content: The user can have recognized content
rendered as a single column, overriding author-specified formatting of
columns, tables, and positioning. (Level AA)

<Jan_> 1.8.14 Multi-Column Text Reflow: The user can specify that
recognized multi-column text blocks each be reflowed into a single column.
(Level AA)

jr: 1.8.9, 1.8.15, 1.8.14 and 1.8.16 are also relevant.

wd: these should go a long way to addressing the multi-column difficulties
we discussed

eh: would this be something for the implementing document to discuss this

jr: yes

wd: it is not an orphan disability. fairly common in people.

jr: user should have ability to manipulate the page to see what works

wd: low vision (with field loss). visual impairment 1/1000 for ages 0-40,
2/1000 40-60, 4/1000 for 65+
... 2 categories - visual acuity loss and field loss (not pure, lots of
overlap), each group has different issues. some need large print/other
small print,
... cloudy vision, light sensitivity (albinism, others), scattered field
(hold head in odd positions to get vision in best spot)
... Legge (psychophysics of reading) many good articles. doesn't matter
what caused the condition functional ability is pretty much the same

<scribe> *ACTION:* jim to rewrite 1.4x to incorporate today's discussion.
[recorded in http://www.w3.org/2014/05/08-ua-minutes.html#action01]

<trackbot> Created ACTION-979 - Rewrite 1.4x to incorporate today's
discussion. [on Jim Allan - due 2014-05-15].

open item 3

js: found this as an item of concern

"In order to claim compliance, the claimant must demonstrate that
solutions, and any required additional components, are available to
non-expert users. Enabling the creation of such solutions is not by itself
sufficient. "

js: do we need to add this to the conformance section?

Jan questioned the test ability of the statement.

ja: meeting ended
