Use the Left Eye Closed patch to make something happen while the user’s left eye is closed.
Track the user’s face from the face tracker.
Output the value to the next patch.
We configured the graph below to make an object appear while the user's left eye is closed.
While the user’s left eye is closed, a check appears to the right of Visible and the object appears on the user’s face.
When the user’s left eye opens, the object is no longer Visible.
