1. A method of controlling movement of a position of an object displayed on a touch screen of a device, the method comprising:
- recognizing intensities of pressure at two or more static positions presented concurrently on the touch screen of the device; and
controlling the movement of the position of the object on the touch screen using a difference in intensities of pressure between the two or more recognized static positions when the difference is greater than a predetermined critical value,wherein controlling the movement of the position of the object comprises;
comparing a distance on a first axis with a distance on a second axis between the two or more static positions;
determining the movement of the position of the object to be in the first axis when the distance on the first axis is longer than the distance on the second axis, or the second axis when the distance on the second axis is longer than the distance on the first axis; and
scrolling the object on the touch screen on which the intensities of pressure at two or more static positions were presented concurrently in the determined movement of the position of the object.

7. An apparatus for controlling movement of a position of an object displayed on a touch screen of a device, the apparatus comprising:
-
a recognition unit configured to recognize intensities of pressure at two or more static positions presented concurrently on the touch screen of the device; and a processing unit configured to control the movement of the position of the object on the touch screen using a difference in intensities of pressure between the two or more static positions when the difference is greater than a predetermined critical value, by comparing a distance on a first axis with a distance on a second axis between the two or more static positions, determining the movement of the position of the object to be in the first axis when the distance on the first axis is longer than the distance on the second axis, or the second axis when the distance on the second axis is longer than the distance on the first axis, and scrolling the object on the touch screen on which the intensities of pressure at two or more static positions were presented concurrently in the determined movement of the position of the object, wherein the object is persistent before and after pressure is applied to the touch screen. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of controlling movement of a position of an object displayed on a touch screen of a device, comprising:
-
recognizing pressures at two or more static positions presented concurrently on the touch screen of the device; and controlling the movement of the position of the object on the touch screen using a difference in pressure between the two or more recognized static positions when the difference is greater than a predetermined critical value, wherein the movement of the position of the object is constrained to one of two orthogonal axes, wherein the two orthogonal axes comprise a first axis and a second axis, and wherein controlling the movement of the position of the object comprises; comparing a distance on the first axis with a distance on the second axis between the two or more static positions; determining the movement of the position of the object to be in the first axis when the distance on the first axis is longer than the distance on the second axis, or the second axis when the distance on the second axis is longer than the distance on the first axis; and scrolling the object on the touch screen on which the intensities of pressure at two or more static positions were presented concurrently in the determined movement of the position of the object. - View Dependent Claims (14, 15)

16. An apparatus for controlling movement of a position of an object displayed on a touch screen of a device, comprising:
-
a recognition unit configured to recognize pressures at two or more static positions presented concurrently on the touch screen of the device; and a processing unit configured to control the movement of the position of the object on the touch screen using a difference in pressure between the two or more static positions when the difference is greater than a predetermined critical value, wherein the movement of the position of the object is constrained to one of two orthogonal axes, wherein the two orthogonal axes comprise a first axis and a second axis, and wherein the processing unit is further configured to; compare a distance on the first axis with a distance on the second axis between the two or more static positions; determine the movement of the position of the object to be in the first axis when the distance on the first axis is longer than the distance on the second axis, or the second axis when the distance on the second axis is longer than the distance on the first axis; and scrolling the object on the touch screen on which the intensities of pressure at two or more static positions were presented concurrently in the determined movement of the position of the object. - View Dependent Claims (17, 18)
