  • Publication number: 20110185008
    Abstract: Methods and apparatus for implementing multi-user casual interactions between users, a plurality of shared display devices, and/or a plurality of third-party devices. The methods include the ability for any user, without any registration prerequisite, to enter content on a handset and to cause certain content changes to be displayed on certain shared display devices, as well as related content information to be sent back to the requesting user's handset and optionally to other users' handsets or to certain third-party devices. The methods also include the ability for an operator to use a graphical user interface to create and manage the rules that control such behavior depending, among other parameters, on the user's submissions or on other users' submissions over a period of time. The methods enable the rules to be extended in an unlimited fashion thanks to the ability to interconnect with a plurality of third-party services.

  • Patent number: 7737980
    Abstract: The present invention provides a method for hierarchically decomposing a visual or audio object within an animation into plurality of objects which can be individually edited to achieve particular animation effects. For example, a graphical object may be decomposed into a plurality of graphical sub-objects, each of which inherits an anchor point from the original object, or is given an original anchor point distinct from the original object. Each sub-object also includes a relative position for the sub-object relative to the anchor point. The path of the anchor point is combined with relative positions of the sub-objects to produce an animation for the object as a whole. This decomposition technique can greatly increase computational efficiency of an animation. It also provides for inheritance of attributes between objects and descendent sub-objects. The objects may support functions, or behaviors, such as morphing or motion blurring.
