+## **PROTOCOLS**
+
+## Control {#Control}
+*Defined in [fuchsia.ui.activity.control/control.fidl](https://fuchsia.googlesource.com/fuchsia/+/master/sdk/fidl/fuchsia.ui.activity.control/control.fidl#21)*
+
+<p>The Control protocol can be used to override the activity state of the
+Activity Service (fuchsia.ui.activity).</p>
+<p>State provided through this interface takes precedence over state which
+is determined based on activity sent through the Tracker API.</p>
+<p>Once a state has been assigned through this protocol, the Activity
+Service will no longer determine state based on input to the
+fuchsia.ui.activity.Tracker protocol, and instead will only report state
+transitions occuring through the Control protocol.</p>
+
+### SetState {#SetState}
+
+<p>Sets the Activity Service's state to |state|.
+All listeners registered through the Provider protocol will immediately
+be notified of the new state.</p>
+<p>Typically, state transitions should occur minutes apart (e.g.
+transition from ACTIVE to IDLE after 15 minutes of inactivity).</p>
