GL: if all control of timing is done by a script then it is up to the author to provide functionality. issue: editorial checks -- review document for 'recognize', 'and/or', initialisms (UA, acromyns, etc.) <trackbot> Created ISSUE-62 - Editorial checks -- review document for 'recognize', 'and/or', initialisms (UA, acromyns, etc.) ; please complete additional details at http://www.w3.org/WAI/UA/tracker/issues/62/edit . discussion of flash threshhold WCAG flash language: Three Flashes or Below Threshold: Web pages do not contain anything that flashes more than three times in any one second period, or the flash is below the general flash and red flash thresholds. (Level A) SH: wants to combine 4.4.1 and 4.4.2 GL: what about 'blink' element. if UA has a hard coded blink rate of 4+ times, then UA is in violation. ... UA that recognizes flashing control should provide a mechanism to limit the number of flashes. WCAG understanding: http://www.w3.org/TR/UNDERSTANDING-WCAG20/seizure-three-times.html <Greg> Actually my point was that if a Web page uses the <BLINK> tag and the UA renders that by flashing the content four times per second, the UA would not violate the currently worded guidelines, but we should revise the guidelines so it would be in violation of something. <Greg> We can either modify 4.4.1 and 4.4.2 to restrict both the UA UI *and* recognized flashing in rendered content, or we could add separate success criteria for the latter. <Greg> To go further, should the UA be required to override recognized Web content attributes that would cause blinking that violates the thresholds? Or, should the UA only be required not to violate them when IT (the UA itself) provides the blink rate? Intent- to avoid causing seizures. <Greg> I suggest that we recommend the user agent provide a user option to constrain recognized blinking in web content to fall within the general flashing and red flashing ranges so as to avoid triggering seizures in individuals with photosensitive seizure disorders. intent - this is about preventing physical harm scribe: to the user two items: user option to set blink rate; and, default flashing rate for interface and content <Greg> "the user interface and default presentation of recognized flashing Web content never violate..."? <scribe> ACTION: Jim to rewrite 4.4.1 to include the user interface and default presentation of recognized flashing Web content never violate and create user has the option to...
