Zooming method, mobile computing device for implementing the zooming method and computer-readable store media

摘要

The present invention relates to a zoom control method, a portable computing device on which the zoom control method is executed, and a storage medium readable by a computer. A zoom control method for a portable computing device according to an embodiment of the present invention is a portable mobile computing that combines a user's pressing and dragging operations input through a touch screen interface with processing of resources displayed in a resource view area on a screen area. Displaying at the device a resource in the resource view area; A second region adjacent to the center of the resource view region, within a first region including or adjacent to a first corner portion of the resource view region, of regions divided by four orthogonal straight lines passing through the center of the resource view region; Defining a first control subregion and a second control subregion adjacent the first corner portion; Activating a zoom mode in the first control subarea or the second control subarea when a pressing operation or a dragging operation of the user is detected through the touch screen interface; Zooming in the resource when the dragging motion is inclined relative to a horizontal edge of the resource view area to approximate the first corner portion of the resource view area; Zooming out the resource when the dragging motion is inclined relative to a horizontal edge of the resource view region to approximate a second corner portion of the resource view region opposite the first corner portion. .
