Content

• The content should be designed in consideration of accessibility issues, including limited vision, limited hearing, and limited mobility, so that all users can choose the options they want.
• - Make sure instructions are clear for all users. Don't refer to a button's shape, color, or location to identify it in instructions. ‘Tap Start’ is effective, but ‘Tap the square button below’ is not. Text or visual feedback needs to supplement audio signals. For example, if you instruct users to ‘Start after the beep’, make sure you provide visual representation of the beep signal.
• - Notifications can include screen displays, sound, vibration, etc. Make sure to give users control over which notification formats they want to use.
• - For multimedia content, provide subtitles, scripts, and sign language where possible. For images, provide alternative text.
• - Avoid strobing effects, sudden and rapid changes in brightness. Warn users if such events will occur.
