F54: Failure of Success Criterion 2.1.1 due to using only pointing-device-specific event handlers (including gesture) for a function


Technologies that have event handlers specific to pointing devices.

User Agent and Assistive Technology Support Notes

This failure relates to:


When pointing device-specific event handlers are the only mechanism available to invoke a function of the content, users with no vision (who cannot use devices such as mice that require eye-hand coordination) as well as users who must use alternate keyboards or input devices that act as keyboard emulators will be unable to access the function of the content.


Failure Example 1

The following example is of an image that responds to a mouse click to go to another page. This is a failure because the keyboard cannot be used to move to the next page. <p><img onmousedown="nextPage();" src="nextarrow.gif" alt="Go to next page"></p>
