Eye tracking not relied on
Core requirement developing
Content and functionality does not rely solely on eye tracking.
Except when eye tracking is essential.
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.
Tests
Procedure
For platforms that use eye-tracking for pointer use:
- Check that an alternative, such as using a switch control, is available.
Expected results
- #1 is true.
