Coordination of static backgrounds and rubberbanding

Abstract

Techniques for coordinating movements of various objects in an electronic document are disclosed. A first-type object remains stationary so that it becomes outside a content boundary of the electronic document, as the content boundary is pulled inside an edge of a window displaying the electronic document. A second-type object remains stationary until the content boundary reaches the edge of the window and then moves along with the scrolled electronic document as the content boundary is pulled inside the edge of the window. A third-type object and a fourth-type object may show different movement behaviors.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims benefit of U.S. Provisional Patent Application No. 62 / 101,346, entitled “COORDINATION OF STATIC BACKGROUND AND RUBBERBANDING,” filed Jan. 8, 2015, the entire contents of which are incorporated herein by reference.FIELD OF THE DISCLOSURE[0002]This disclosure relates generally to a coordination of movements on a display of an electronic document and one or more objects contained in the electronic document.BACKGROUND OF THE DISCLOSURE[0003]Modern display techniques often involve displaying moving contents on a display, for example, displaying a moving electronic document that includes other objects (e.g., text blocks, images, etc.). However, with an increasing complexity of movements required for electronic documents and individual components contained therein in modern display designs, a streamlined coordination of different movement behaviors of the electronic document and the contained objects is becoming more and ...

AI Technical Summary

Benefits of technology

The patent describes a method for coordinating the movements of an electronic document that includes different objects. When the document is scrolled, the electronic device detects user input and moves the document accordingly. This movement behavior can include a rubber-band effect, where the document is pulled out from underneath the first object in the document. The patent also describes how to refresh the displayed document by using the rubber-band effect. The techniques described in this patent can be applied to various animation effects and can be used on electronic devices with touch-sensitive displays.

Problems solved by technology

However, with an increasing complexity of movements required for electronic documents and individual components contained therein in modern display designs, a streamlined coordination of different movement behaviors of the electronic document and the contained objects is becoming more and more difficult.
