Issue
This is how Ally describes this issue:
- The image can induce seizures.
Some students are sensitive to animated images that flash or contain intense visual patterns. These types of images can trigger seizures or other adverse physical reactions, particularly for individuals with photosensitive epilepsy. To create a safer and more accessible learning environment, avoid using this type of content whenever possible and replace it with non-animated or less intense alternatives.
Quick Fix
Remove or replace potentially harmful flashing content.
To apply the quick fix:
- Locate the issue named “The image can induce seizures.”
- Select the issue to view the affected files.
- Select the red or orange Ally Accessibility Indicator icon next to the file.
- The image will appear on the left side of your screen with a warning that it is “potentially seizure-inducing”, and the Instructor Feedback panel will be on your right.
- Review the animation for rapid flashing or blinking.
- If the content exceeds three flashes per second, select Remove it, followed by Remove now. Replace it with content that does not flash or that flashes fewer than three times per second.
- If the animation does not exceed three flashes per second or it does not flash or blink, select No, I need to keep it. Selecting this option does not currently improve you’re Ally score, but this issue has been reported to Ally.
- Close the issue and move to the next item in your list.
