developing Core requirement

Haptic Stimulation Adjustable

Group: animation-and-movement • Guideline: avoid-physical-harm

Summary in Plain English

Vibration and other haptic feedback the content triggers must be reducible or switchable off. Haptics the operating system generates on the user's own request are out of scope.

Why It Matters

Vibration can cause pain for people with chronic pain conditions or tremor, and it can be startling or disorienting for people with sensory processing differences.

Scope: When This Applies

The draft's own conditions, quoted from guidelines/groups/animation-and-movement/avoid-physical-harm/haptic-stimulation-adjustable.md.

Applies when

  • content triggers haptic feedback.

Except when

  • the operating system or user agent converts non-haptic feedback to haptics at user request.
