Eye Tracking Not Relied On
Summary in Plain English
Content and functionality cannot rely solely on eye tracking, unless eye tracking is essential.
Why It Matters
Eye tracking assumes steady, controllable gaze. Nystagmus, strabismus, low vision and blindness all make it unreliable or impossible.
Scope: When This Applies
The draft's own conditions, quoted from guidelines/groups/input-operation/input-operation/eye-tracking-not-relied-on.md.
Except when
- Eye tracking is essential.
Notes in the draft
This is primarily aimed at ensuring there is an alternative for people who cannot use eye tracking (but do have sight) due to eye conditions.
Some platforms may only allow eye tracking. Ideally the platforms allow additional mechanisms for control.
