Tasking systems and methods are provided that support user interfaces for displaying objects, the displayed objects enabling user access to resources that provide for effecting tasks among the system and devices of the systems' environment. More particularly, tasking systems and methods are provided that support the foregoing features, wherein the systems and methods support clustering operations respecting such task-associated objects so as to enhance the effecting of the associated tasks, such clustering operations responding to context. The clustering operations preferably are both adaptive and dynamic. Tasking systems and methods preferably support the tracking of selected states, including, as examples, one or more of environment states, device states, and system states. Tracked states typically also include states respecting other relevant criteria, such as temporal criteria.
