RE: SC 1.3.3 - text alternative or no visible label?

Ø  There is some debate at my work about whether (non-decorative) 'graphical symbols' need to have visible labels when they provide instruction.

This question has been raised before.  If I recall correctly it was determined at the time that the intention of the success criteria was not to require text for icons but instead to address descriptions that relied on sensory information such as bottom right, red button, etc.  From what I understand at this time icons can be used to communicate information without other visual text labels.  I understand this is problematic for some users and I believe is something that is being discussed in the different task forces for future WCAG updates.  In keeping with that discussion - yes, F26 might be more correctly placed under SC 1.1.1.  You may want to log an issue https://github.com/w3c/wcag/issues

Subject: SC 1.3.3 - text alternative or no visible label?

hi all,

There is some debate at my work about whether (non-decorative) 'graphical symbols' need to have visible labels when they provide instruction.

So I have a question about SC1.3.3.

Is it reasonable to infer from SC1.3.3 that instructions conveyed non-verbally must be accompanied by some form of visible text?

For example, a button with a triangle icon indicating current state (or is it indicating outcome?) that rotates 90º and toggles an expandable section. The button includes offscreen text that says 'show/hide xyz'.

Is this sufficient to meet SC  1.3.3?

Should anything be read into the use of 'glyph' and 'symbol' in failure technique F26?

Should F26 be under SC1.1.1 instead?

cheers,
Adam
