<scribe> Meeting: HTML 5 Canvas Accessibility subteam meeting
Rich: I have been thinking about coords
Chuck: I have been using CSS to
give it a rectangle but it works rather well
... The value of CSS is that if canvas could not be drawn it could be used
... The SVG group is working on on accessibility as well
... The best thing would be if the AT could send a request to the scripting environment
... It sounds like focus ring would work but we are talking about access to things that do not have focus
Rich: Correct. That is what AISquared wanted
Chuck: I see what they want but I
am trying to find an elegant way of doing it
... it really should be callback based
... There are ways for the AT to walk the DOM.
Rich: moving focus to get things messes up the user experience
Chuck: I think for zoomtext that
there are features they can use to get what they want
... This does not quite fix how canvas works
... Instead of putting all the things in the DOM I add or remove things from the DOM.
Rich: If you pull things out of the DOM this could mess up review mode
Chuck: the situation where you
treat all elements like a list it is more canvas like
... I can say I have all of these and I need to rotate them all
... SVG benefits from being bound to the drawing surface
Rich: HTML is the same way. We
just are not bound.
... is there a way to create an object in canvas that could be bound to the corresponding fallback object.
Chuck: there is only one object
for the canvas
... if you are looking at an entire haptic screen ...
... a Braille devices is more text based
... I could use some use cases.
... At this point it is mostly a touch based screen
... there is no real drawing object. There is just drawing primitives. There is no positioning information
Rich: I wonder what the value would be if we had a drawing object.
Chuck: Has a create path item in Canvas API 2.0
Rich: it might be a good thing to create a collection of drawing functions into an object and compute the bounding rectangle
Chuck: Essentially, the SVG path
provides a similar function
... ARIA is rich enough. If you set an ARIA tag on an element then you do this ...
... right now I am going through my mac. etc.
... there is nothing in these ATs that require that yet
... The text finder in Zoomtext is the closest. It uses focus
Rich: I will look at SVG path
... it is perfectly valid to use the SVG path.
Chuck: I have been working on it
... the drawfocus ring using divs does work
... I put a div in a div in contenteditable and got the caret blinking
... I set the text color to be transparent. I used absolute positioning.
... It worked
Chuck: Nothing has happened
... no success yet
Rich: I will look at SVG paths
Chuck: I will modify darkroom demo to address moving your mouse over something to hear what is going on.
<Downchuck> might try to track down some bspin devs
<Downchuck> they weren't treated very well in mozilla for their use of canvas; but they have good input on things
