Interaction patches handle user input from views. Views send touch information to these patches via their Interaction port. Unlike other connections, these connections start from the View and move from right to left.
Gesture patches recognize gestures on views. They behave similarly to Interaction patches with the exception that they have the ability to block other interactions and gestures.
Hovering the mouse over a connection inspects the data flowing through it. Connection values only will appear while the document is connected to a device.
