Systems and methods for node tracking and notification in a control framework including a zoomable graphical user interface
First Claim
1. In control framework having a plurality of nodes, a subset of said plurality of nodes associated with a displayed portion of a graphical user interface (GUI), a method for tracking said plurality of nodes comprising the steps of:
- maintaining a data structure which contains boundary information associated with each of said subset of nodes;
changing said displayed portion of said GUI, which is displayed on a television, from a first portion to a second portion;
evaluating said data structure based upon said changing step to determine whether a node has moved into or out of said displayed portion of said GUI; and
selectively notifying said node based on a result of said evaluating step.

Abstract
Systems and methods according to the present invention provide a control framework for organizing, selecting and launching media items including graphical user interfaces coupled with an optional 3D control device for collection of the basic control primitives of point, click, scroll, hover and zoom which permit for easy and rapid selection of media items, e.g., movies, songs etc., from large or small collections. The remote control maps natural hand movements and gestures into relevant commands while the graphical display uses images, zooming for increased/decreased levels of detail and continuity of GUI objects to provide easy organization, selection and navigation among the media items by a user.

22. A non-transitory computer-readable medium containing an executable program that performs the steps of:
-
maintaining a data structure which contains boundary information associated with each of a subset of nodes; changing a displayed portion of a graphical user interface (GUI) from a first portion to a second portion; evaluating said data structure based upon said changing step to determine whether a node has moved into or out of said displayed portion of said GUI; and selectively notifying said node based on a result of said evaluating step. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
