Use the Smile patch to make something happen while the user smiles.
The Smile patch only detects mouth movements. If you want to detect movements across the face to determine that the user looks happy, use the Happy Face patch.
Track the user’s face from the face tracker.
Output the value to the next patch.
In the example below, an object appears when the user smiles. The object disappears when the user no longer smiles.
To do this, we connected the output on the Smile patch to the Visible input on the object patch.
