METHOD FOR PANNING IMAGE THROUGH VIEWPORT, GRAPHICAL USER INTERFACE INTERNALLY DISPLAYING VIEWPORT, AND COMPUTING DEVICE CONFIGURED TO INTERACT WITH ANOTHER COMPUTING DEVICE

PROBLEM TO BE SOLVED: To provide a viewpoint panning feedback system. SOLUTION: 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. COPYRIGHT: (C)2007,JPO&INPIT
