Action 1047 follows – if the second example for 1.1.5b doesn't work we
can leave it out.
Cheers,

ACTION-1047 - Split 1.1.5 so that the first two bullets are a and the
third bullet is aa. ier and handles must be split as well. [on Kimberly
Patch - due 2014-11-04].
*SUGGESTED CHANGES*
1.1.5a
For recognized
<http://w3c.github.io/UAAG/UAAG20/#def-recognize>on-screen alternative
content for time-based media (e.g. captions, sign language video), the
following are all true: (Level A)
* Don't obscure controls:Displaying time-based media alternatives
doesn't obscure
<http://w3c.github.io/UAAG/UAAG20/#def-obscure>recognized controls
for the primary time-based media.
* Don't obscure primary media:The user can specify that displaying
time-based media alternatives doesn't obscure the primary time-based
media.
* Note: Depending on the screen area available, the display of the
primary time-based media may need to be reduced in size to meet this
requirement.
Intent of Success Criterion 1.1.5:
Users who require or can benefit from alternative media tracks in video
or audio might find that the default or authored position and size of
those tracks is unusable. Enabling the user to move and scale any
displayed alternate media tracks (e.g. captions) allows displayed
content to be positioned and sized to meet the needs of the user.
Examples for Success Criterion 1.1.5:
* Jaime is deaf and is taking courses from on online university. She
prefers to use ASL if it is available for online media. A course she
is taking offers captions and a signing avatar for the recorded
lectures. The default size of the avatar window is small, making it
difficult to follow the signing. The avatar also overlays a
significant part of the lecture video. Jaime drags the avatar out of
the video and enlarges it, so that they are side by side and equally
sized.
* [mobile] Jaime is deaf and prefers to always display captions on her
mobile phone. She has set her global settings on the phone to turn
on closed captions. All videos displayed on the phone will
automatically display captions.
* [mobile] Ben has low vision that becomes worse throughout the day as
he becomes more tired. He keeps a floating control on his mobile
phone that allows one touch access to his configuration so that he
can change the font size. The floating control can be easily moved
around the screen so it is not in the way of other controls, and it
becomes translucent after it is idle for a few seconds.
1.1.5b
For recognized
<http://w3c.github.io/UAAG/UAAG20/#def-recognize>on-screen alternative
content for time-based media (e.g. captions, sign language video), the
user can configure recognized text within time-based media alternatives
(e.g. captions) in conformance with 1.4.1
<http://w3c.github.io/UAAG/UAAG20/#sc_141>.
* Note: Depending on the screen area available, the display of the
primary time-based media may need to be reduced in size to meet this
requirement.
Intent of Success Criterion 1.1.5:
Users who require or can benefit from alternative media tracks in video
or audio might find that recognized text displayed within alternate
media tracks is unusable due to its configuration. Enabling the user to
configure alternate media tracks (e.g. captions) allows content to be
displayed in a way that meets the needs of the user.
Examples for Success Criterion 1.1.5:
* Justin has low vision and works in a noisy environment that makes it
difficult to listen to instructional videos. When he enlarges the
text of the captions to a viewable size, they block most of the
video image. When he is using his tablet, Justin selects an option
that displays the caption track in a separate window, which he
positions below the video image so the captions don't block the
video image.
* Justin has low vision and works in a noisy environment that makes it
difficult to listen to instructional videos. When he enlarges the
text of the captions to a viewable size, they block most of the
video image. When he is using his smart phone, Justin selects an
option that causes the video to pause when the caption track comes
on so he can read it, then turns the caption track off so he can see
the video using the full screen.
*ORIGINAL*
1.1.5 Facilitate Clear Display of Alternative Content for Time-based Media:
For recognized

for the primary time-based media.
* Don't obscure primary media:The user can specify that displaying
time-based media alternatives doesn't obscure the primary time-based
media.
* Use configurable text:The user can configure recognized text within
time-based media alternatives (e.g. captions) in conformance with
1.4.1 <http://w3c.github.io/UAAG/UAAG20/#sc_141>.
* Note: Depending on the screen area available, the display of the
