Use the Happy Face patch to make something happen while the user makes a happy face.
The Happy Face patch detects movements across the face, such as the movement of the corners of the mouth and raising eyebrows.
If you only want to detect mouth movements, use the Smile 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 makes a happy face. The object disappears when the user no longer makes a happy face.
To do this, we connected the output on the Happy Face patch to the Visible input on the object patch.
