Which of the following is a recommended method in the W3C standards in the operability category to improve accessibility of a website on a tablet computer?

• A. Provide a virtual magnifying glass that enlarges portions of a website
• B. Placing critical information at the top of the page
• C. Provide adequate contrast to make onscreen content visible in bright environments
• D. Provide workarounds for actions triggered by physically moving the tablet

Answer: (D)

Operability on a tablet is about making interactions usable with multiple input methods, not just motion-based gestures. The recommended approach is to provide workarounds for actions triggered by physically moving the device, so users who can’t tilt, shake, or rotate the tablet can still perform essential actions through alternative controls like on-screen buttons or other input methods. This aligns with WCAG guidance that motion-based input should have non-motion alternatives to ensure access for users with mobility or dexterity limitations. The other options touch on magnification, layout, or contrast, which improve accessibility in different ways but don’t specifically address input methods or motion-based actions the way offering alternatives does.
