Single-pointer action not available

Rule

All functionality that can be operated with a pointer MUST be operated with only single-pointer actions. Path-based or multi-point gestures MUST NOT be required to operate any functionality. Exceptions exist.

Background

When functionality requires complex gestures, such as multi-point or path-based gestures, people with motor disabilities may find it difficult or impossible to perform the gesture, either because they may lack the accuracy necessary to carry it out or because they use an assistive technology that lacks the capability or accuracy. An alternative method to accomplish the same function that relies only on single-pointer actions that are not path-based must be provided. This allows people with low dexterity or who use assistive technologies to access the functionality, as well as aids people with cognitive disabilities who may not know about or understand the required complex gesture. NOTES: Examples of path-based gestures include swiping, sliders and carousels dependent on the direction of interaction, and other gestures which trace a prescribed path such as the drawing a specific shape. Such paths may be drawn with a finger or stylus on a touchscreen, on a graphics tablet or trackpad, or with a mouse, joystick, or similar pointer device. Examples of multi-point gestures include a two-finger pinch zoom, a split tap where one finger rests on the screen and a second finger taps, or a two or three finger tap or swipe.

How to Fix

Fix this issue by providing an alternative method to accomplish the same function that relies only on single-pointer actions that are not path-based. The alternative method can replace the current method or be an additional method. Examples of single-pointer activation on a touchscreen or touchpad include taps, double taps, long presses, and dragging actions that are not path-based. Examples for a mouse or trackpad include single clicks, click-and-hold, double clicks, and dragging actions that are not path-based.
