developing Core requirement
Pointer Speed Not Relied On
Summary in Plain English
Functionality cannot depend on moving the pointer at a particular speed, unless that speed is essential.
Why It Matters
Speed requirements like double-click timing or a fast flick exclude people whose movements are slow or variable, including many older users.
Scope: When This Applies
The draft's own conditions, quoted from guidelines/groups/input-operation/pointer-input/pointer-speed-not-relied-on.md.
Except when
- Specific pointer speed is essential to the functionality.
Examples from the Draft
Worked examples the W3C editors wrote into the provision itself, not examples invented here.
Specific pointer speed would be essential to a paintbrush feature, advanced signature verification, or time-constrained gaming.
