Embodiment Construction

[0042] Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, several specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

[0043] It should also be understood that although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departin...

Abstract

The invention relates to a method and a device for scrolling a multi-section document and a multifunctional device. The method includes displaying on a display an electronic document that includes a plurality of document sections separated by corresponding logical structure boundaries; detecting a gesture on a touch-sensitive surface, the gesture having an initial velocity that exceeds a predefined speed threshold so that the gesture will scroll the electronic document more than one document section; initiating scrolling of the electronic document on the display at the initial velocity in accordance with an initial scrolling speed versus scrolling distance function; while scrolling the electronic document, adjusting the scrolling speed versus scrolling distance function so that when the scrolling speed becomes zero, a first logical structure boundary in the electronic document is displayed at a predefined location on the display; and scrolling the electronic document in accordance with the adjusted scrolling speed versus scrolling distance function. The invention reduces the cognitive burden on a user, and thereby produces a more efficient human-machine interface. The invention enables a user to scroll the multi-section document in a more rapid and more efficient manner, conserves power and increases the time between battery charges.

Description

technical field [0001] Embodiments of the present invention generally relate to electronic devices with touch-sensitive surfaces, and more particularly, to methods for heuristically scrolling multi-section electronic documents to improve the display of electronic documents and electronic devices with touch-sensitive surfaces. Background technique [0002] The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touch pads and touch screen displays. Such surfaces are widely used to manipulate user interface objects on displays. [0003] Many users rely on electronic computing devices with touch-sensitive surfaces and displays to view and manipulate multi-section electronic documents. In these cases, the user can browse the electronic document by means of gestures on the touch-sensitive surface or touch screen of the device. Unfortunately,...
