A center area and an outer area of the picture displayed on the touch-sensitive screen are defined. An image processing operation, such as zooming in, zooming out, or movement on the picture displayed on the touch-sensitive screen is performed based on the relationship of the initial location and the orientation of the sliding motion, and the center area and the outer area of the picture. Therefore, basic picture operations can be carried out by a single finger possibly while holding the device with the same palm to improve usability and to user safety. ## Claims ### Claim 1 A computing device-implemented method, comprising: detecting, by a processor of the computing device, that a sliding motion is being made on a touch screen of the computing device; detecting, by the processor and in response to detecting the sliding motion, an initial location and an initial orientation of the sliding motion; identifying, by the processor and in response to detecting the sliding motion and the initial location and the initial orientation of the sliding motion, an item, being displayed by the touch screen, wherein a center area and an outer area of the item are defined; and zooming in or zooming out, by the processor, on the item displayed on the touch screen based on the relationship of the initial location and the initial orientation of the sliding motion, and the center area and the outer area of the item and in response to the processor detecting that the sliding motion is being made on the touch screen. ### Claim 2 (depends on 1) The method of claim 1, wherein the outer area is 15% of a width and a height of the item counting from edges of all sides of the item and the center area covers the remaining area of the item, totaling 70% of the width and height of the item. ### Claim 3 (depends on 2) The method of claim 2, wherein when the initial location is located at the center area and the initial orientation of the sliding motion is towards to a focal point of the item, the zooming out from the same initial location is performed by the processor as long as the sliding action continues regardless of a later direction of the same sliding action. ### Claim 4 (depends on 2) The method of claim 2, wherein when the initial location is located at the center area and the initial orientation of the sliding motion is outwards from a focal point of the item, the zooming in to the same initial location is performed by the processor as long as the sliding motion continues regardless of a later direction of the same sliding motion. ### Claim 5 (depends on 2) The method of claim 2, wherein when the initial location is located at a focal point of the item, the zooming in to the same initial location is performed by the processor. ### Claim 6 (depends on 2) The method of claim 2, wherein when the initial location is located at a boundary of the center area, the zooming out from or in to the same initial location is performed by the processor depending on the initial orientation of the sliding motion. ### Claim 7 (depends on 2) The method of claim 2, wherein when the item is zoomed in, and the initial location is located at the outer area, the item is moved by the processor along the orientation of the sliding motion. ### Claim 8 (depends on 1) The method of claim 1, further comprising: storing, in a memory of the computing device, a plurality of parameters, the parameters being associated with how the zooming in or zooming out is performed by the processor. ### Claim 9 (depends on 8) The method of claim 8, wherein the parameters include a minimum size parameter that indicates a percentage of an original size to which the item can be zoomed out, where the original size corresponds to a displayed size of the item prior to detecting the sliding motion, and where zooming in or zooming out on the item includes: zooming out on the item to a size corresponding or exceeding the minimize size parameter. ### Claim 10 (depends on 8) The method of claim 8, wherein the plurality of parameters include a maximum size parameter that indicates a percentage of an original size to which the item can be zoomed in, where the original size corresponds to a displayed size of the item prior to detecting the circular motion, and where zooming in or zooming out on the item includes: zooming in on the item to a size at or below the maximum size parameter. ### Claim 11 A computing device, comprising: a touch-sensitive screen; a memory to store a plurality of instructions; and a processor to execute instructions in the memory to: detect a sliding motion is being made on the touch-sensitive screen; detect, in response to detecting the sliding motion, an initial location and an initial orientation of the sliding motion; identify, in response to detecting the sliding motion and the initial location and the initial orientation of the sliding motion, an item, being displayed by the touch screen, wherein a center area and an outer area of the item are defined; and zoom in or zoom out on the item displayed on the touch-sensitive screen, in response to the processor detecting that the sliding motion is being made on the touch-sensitive screen, based on the relationship of the initial location and the orientation of the sliding motion, and the center area and the outer area of the item. ### Claim 12 (depends on 11) The device of claim 11, wherein the outer area is 15% of a width and a height of the item counting from edges of all sides of the item and the center area covers the remaining area of the item, totaling 70% of the width and height of the item. ### Claim 13 (depends on 12) The device of claim 12, wherein when the initial location is located at the center area and the initial orientation of the sliding motion is towards to a focal point of the item, the zooming out from the same initial location is performed by the processor as long as the sliding motion continues regardless of a later direction of the same sliding motion. ### Claim 14 (depends on 12) The device of claim 12, wherein when the initial location is located at the center area and the initial orientation of the sliding motion is outwards from a focal point of the item, the zooming in to the same initial location is performed by the processor as long as the sliding motion continues regardless of a later direction of the same sliding motion. ### Claim 15 (depends on 12) The device of claim 12, wherein when the initial location is located at a focal point of the item, the zooming in to the same initial location is performed by the processor. ### Claim 16 (depends on 12) The device of claim 12, wherein when the initial location is located at the boundary of the center area, zooming out from or in to the same initial location is performed by the processor depending on the initial orientation of the sliding motion. ### Claim 17 (depends on 12) The device of claim 12, wherein when the item is zoomed in, and the initial location is located at the outer area, the item is moved by the processor along the orientation of the sliding motion. ### Claim 18 (depends on 11) The device of claim 11, wherein the memory further comprises a plurality of parameters, the parameters being associated with how the zooming in or zooming out is performed by the processor. ### Claim 19 (depends on 18) The device of claim 18, wherein the parameters include a minimum size parameter that indicates a percentage of an original size to which the item can be zoomed out, where the original size corresponds to a displayed size of the item prior to detecting the sliding motion, and where zooming in or zooming out on the item includes: zooming out on the item to a size corresponding or exceeding the minimize size parameter. ### Claim 20 (depends on 18) The device of claim 18, wherein the plurality of parameters include a maximum size parameter that indicates a percentage of an original size to which the item can be zoomed in, where the original size corresponds to a displayed size of the item prior to detecting the sliding motion, and where zooming in or zooming out on the item includes: zooming in on the item to a size at or below the maximum size parameter.
