-        This interface allows to monitor user idle time on a given seat. The interface
-        allows to register timers which trigger after no user activity was registered
-        on the seat for a given interval. It notifies when user activity resumes.
-
-        This is useful for applications wanting to perform actions when the user is not
-        interacting with the system, e.g. chat applications setting the user as away, power
-        management features to dim screen, etc..
