Operable 2.5 – Input modalities

2.5.1 Pointer Gestures A All functionality that uses multipoint or path-based gestures for operation can be operated with a single pointer without a path-based gesture, unless a multipoint or path-based gesture is essential.

2.5.2 Pointer Cancellation A For functionality that can be operated using a single pointer, at least one of the following is true:

No Down-Event:

The down-event of the pointer is not used to execute any part of the function;

Abort or Undo:

Completion of the function is on the up-event, and a mechanism is available to abort the function before completion or to undo the function after completion;

Up Reversal:

The up-event reverses any outcome of the preceding down-event;

Essential:

Completing the function on the down-event is essential.

2.5.3 Label in Name A For user interface components with labels that include text or images of text, the name contains the text that is presented visually.

2.5.4 Motion Actuation A Functionality that can be operated by device motion or user motion can also be operated by user interface components and responding to the motion can be disabled to prevent accidental actuation, except when:

Supported Interface:

The motion is used to operate functionality through an accessibility supported interface;

Essential:

The motion is essential for the function and doing so would invalidate the activity.
