Benefits of technology

[0010] In yet another embodiment, a computing device configured to interact with other computing devices is provided. The computing device includes a central processing unit (CPU) and a memory storing a sharing application. The sharing application enables the computing device to create a virtual link with one of the other computing devices so that input devices of the computing device appear physically connected to another of the computing devices. A display screen configured to display a first portion of image data from the one of the other comput

Problems solved by technology

Typically it is difficult or impossible to contain the entire digital content at the required scale within the available display area or window region.
The window containing the viewport window typically provides some means for adjusting the position of the viewport over the source content, thus affecting

Embodiment Construction

[0025] An invention is described for an apparatus and method that provides visual feedback, which includes dynamic rate and directional information to a computer user during interactive panning of a viewport over a source surface. It will be obvious, however, to one skilled in the art, that the present invention may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the present invention.

[0026] The embodiments described below provide a graphical user interface (GUI) that enables a user to configure the panning functionality. In addition, the system enabling the GUI is configured to provide visual feedback to a user during interactive panning of the viewport over source image data. In one embodiment, the user is given fine-grained configurable control over the rate of speed and direction of the panning operation. Additionally, all elements of the invention

Abstract

A graphical user interface (GUI) displaying a viewport includes a panning control region defined within an outer boundary of the viewport within the GUI. The panning control region includes multiple segments, each of the multiple segments corresponding to a panning direction, wherein a panning rate is indicated by a level of translucency of the multiple segments. A panning available region defined along the outer boundary of the viewport within the GUI is included. The panning available region indicates whether a source image extends beyond an edge of the viewport, and the panning available region is a subset of the panning control region. A method for panning an image through a viewport and a computing device are also provided.
