The method of driving an electronic device including an input unit into which information is input by a touch and a screen display unit on which a pointer is displayed in response to the touch includes: a first step of moving the pointer from a point at which the touch is applied to the input unit first in an arbitrary direction in which drag of the pointer is performed; a second step of stopping the movement of the pointer when the drag is stopped; and a third step of additionally moving the pointer in a direction, which is directed from the point at which the touch is applied first to a point to which pressing pressure is applied, in response to pressing pressure when the drag is stopped. ## Claims ### Claim 1 A method of driving an electronic device including an input means into which information is input by a touch and a screen display means on which a pointer is displayed in response to the touch, the method comprising: a first step of moving the pointer from a point at which the touch is applied to the input means first in an arbitrary drag direction in which the pointer undergoes drag; a second step of stopping the movement of the pointer when the drag is stopped; and a third step of additionally moving the pointer in a direction, which is directed from the point at which the touch is applied first to a point to which pressing pressure is applied, in response to pressing pressure when the drag is stopped. ### Claim 2 (depends on 1) The method according to claim 1, further comprising: a fourth step of moving the pointer in the drag direction when the drag is additionally carried out to another point based on the point to which the pressing pressure is applied; a fifth step of stopping the movement of the pointer when the drag is stopped in the fourth step; and a sixth step of additionally moving the pointer in the drag direction in response to the pressing pressure at the point at which the drag is stopped. ### Claim 3 (depends on 1) The method according to claim 1, wherein, when the pressing pressure is applied to the same point twice or more, the pointer is subjected to a change in movement speed in correspondence with the applied pressing pressure. ### Claim 4 (depends on 1) The method according to claim 1, wherein the pointer is subjected to a change in movement speed in response to magnitude of the pressing pressure. ### Claim 5 (depends on 4) The method according to claim 4, wherein the pointer moves at two or more different speeds according to the magnitude of the pressing pressure. ### Claim 6 (depends on 1) The method according to claim 1, wherein the pressing pressure is implemented by a switching operation. ### Claim 7 (depends on 1) The method according to claim 1, wherein the pressing pressure is detected by a pressure sensor or a tactile sensor. ### Claim 8 (depends on 1) The method according to claim 1, wherein the pointer has a movement speed determined depending on the drag speed in response to the pressing pressure when the drag is stopped. ### Claim 9 (depends on 1) The method according to claim 1, wherein the input means includes a touchscreen or a touchpad. ### Claim 10 An apparatus for driving an electronic device comprising: a housing having a seat recess; an input signal transfer main body that is fitted into the seat recess in whole or in part, and controls movement of a pointer displayed on a screen display unit; a direction detecting means that is located on the top of the input signal transfer main body, and generates a movement direction signal of the pointer; and a speed detecting means that is located at the bottom of the input signal transfer main body, and generates an additional movement signal or a movement speed change signal of the pointer in response to pressing pressure of the input signal transfer main body when the pressing pressure is applied, wherein the movement of the pointer displayed on the screen display unit is controlled using at least one of the movement direction signal of the pointer which is generated by the direction detecting means, the additional movement signal of the pointer which is generated by the speed detecting means, and the movement speed change signal of the pointer which is generated by the speed detecting means. ### Claim 11 (depends on 10) The apparatus according to claim 10, wherein, when the pressing pressure of the input signal transfer main body is applied to the same point twice or more, the pointer is subjected to a change in movement speed in correspondence with the applied pressing pressure. ### Claim 12 (depends on 11) The apparatus according to claim 11, wherein the pressing pressure of the input signal transfer main body is implemented by a switching operation. ### Claim 13 (depends on 10) The apparatus according to claim 10, wherein the pointer is subjected to a change in movement speed in response to magnitude of the pressing pressure of the input signal transfer main body. ### Claim 14 (depends on 13) The apparatus according to claim 13, wherein the pressing pressure of the input signal transfer main body is detected by a pressure sensor or a tactile sensor. ### Claim 15 (depends on 10) The apparatus according to claim 10, wherein the direction detecting means includes a touchpad.
