Yvette's reformulation is close to the one I proposed some time back. In fact hers may be clearer; I'll paste my proposed wording in below for comparison. <begin proposed wording> Proposed wording for Who benefits from Checkpoint 2.3 (Informative) * People with photosensitive epilepsy benefit from the absence of flickering content. For these individuals, seizures can be triggered by flickering in the range between 3 and 49 times per second (3-49Hz), with a peak sensitivity at 20 flashes per second. * People who are easily distracted may be able to concentrate better if they are not distracted by content flickering in the visual field. </end proposed wording> "Good design is accessible design."

Hoitink Sent: Thursday, March 04, 2004 11:29 am To: w3c-wai-gl@w3.org Subject: [2.3] Benefits formulated as problems (low priority) Hi everyone, While rereading the current working draft, I noticed that the benefits of 2.3 (about seizures) are formulated in reverse compared to the other guidelines. All the other guidelines formulate the benefits of the guideline. In guideline 2.3, it lists in the "who benefits" section: * Individuals with photosensitive epilepsy can have seizures triggered by flickering or flashing in the 3 to 49 flashes per second (Hertz) range with a peak sensitivity at 20 flashes per second. * Individuals who are easily distracted may not be able to focus on content with flicker occurring in the same visual field. Of course, the benefits are that these effects are avoided. I think we should formulate all the "who benefits" sections as benefits, not as implicitely avoided negative effects. Proposed reformulation: * Individuals with photosensitive epilepsy can avoid content that causes them to have seizures. These seizures are triggered by flickering or flashing in the 3 to 49 flashes per second (Hertz) range with a peak sensitivity at 20 flashes per second. * Individuals who are easily distracted find it easier to focus on content without flicker occurring in the same visual field.
