store a discrimination value for determining if the first or second touch gesture is by a touch pen; and a controller configured to compare an attribute of the first touch gesture with the discrimination value, receive the first touch gesture as being from the touch pen when the attribute of the first touch gesture is within a predetermined value or range of the discrimination value, and execute an operation corresponding to the touch pen based on the first touch gesture being received as the touch pen. ## Claims ### Claim 1 A mobile terminal, comprising: a touchscreen configured to receive an input of a first touch gesture and a second touch gesture; a memory configured to store a discrimination value for determining if the first or second touch gesture is by a touch pen; and a controller configured to: compare an attribute of the first touch gesture with the discrimination value, receive the first touch gesture as being from the touch pen when the attribute of the first touch gesture is within a predetermined value or range of the discrimination value, and execute an operation corresponding to the touch pen based on the first touch gesture being received as the touch pen. ### Claim 2 (depends on 1) The mobile terminal of claim 1, wherein the first and second touch gestures are input to the touchscreen simultaneously or consecutively in a random order. ### Claim 3 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to receive the second touch gesture as being from a portion of a user's hand when the first touch gesture is received as being from the touch pen. ### Claim 4 (depends on 1) The mobile terminal of claim 1, wherein the touch pen comprises a passive stylus pen. ### Claim 5 (depends on 1) The mobile terminal of claim 1, wherein the discrimination value comprises at least one touch attribute value of a touch gesture previously input by the touch pen. ### Claim 6 (depends on 1) The mobile terminal of claim 1, wherein the discrimination value comprises an average range value of a strength of static electricity generated from a touch gesture previously input by the touch pen, and wherein the controller is further configured to determine the first touch gesture as being from the touch pen when the first touch gesture has an electrostatic strength belonging to the average range value in the recognized electrostatic strength. ### Claim 7 (depends on 1) The mobile terminal of claim 1, wherein the discrimination value comprises an average range value of a touch area of a touch gesture previously input by the touch pen, and wherein the controller is further configured to determine the first touch gesture as being from the touch pen when the first touch gesture has a size of the touch area belonging to the average range value in the recognized touch area of the first. ### Claim 8 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to recognize pattern change amounts of the first and second touch gestures and determine a touch gesture having a greater change amount in the recognized touch pattern change amounts of the first and second touch gestures as the first touch gesture. ### Claim 9 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to recognize per-time touch moving distances of the first and second touch gestures and determine a touch gesture having a greater moving distance in the recognized per-time touch moving distances of the first and second touch gestures as the first touch gesture. ### Claim 10 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to ignore the input second touch gesture and perform the operation corresponding to the first touch gesture only when the first touch is received as being from the touch pen. ### Claim 11 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to discriminately display input on the touchscreen corresponding to the first touch gesture as being received from the touch pen. ### Claim 12 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to display information indicating a portion of the touchscreen except a portion corresponding to the second touch gesture is a region inputtable by the touch pen. ### Claim 13 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to discriminately display a pattern corresponding to the first touch gesture than a pattern corresponding to the second touch gesture. ### Claim 14 (depends on 13) The mobile terminal of claim 13, wherein the controller is further configured to maintain the pattern corresponding to the first touch gesture and to gradually remove the pattern corresponding to the second touch gesture. ### Claim 15 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to display a pattern input by the first touch gesture on the touchscreen and edit the displayed pattern corresponding to the second touch gesture. ### Claim 16 (depends on 15) The mobile terminal of claim 15, wherein the controller is further configured to increase and decrease a size of the pattern input by the first touch gesture based on a movement of the second touch gesture. ### Claim 17 (depends on 15) The mobile terminal of claim 15, wherein the controller is further configured to display an editing menu for editing the pattern input by the first touch gesture based on the received second touch gesture and edit the pattern input by the first touch gesture based on selections made in the editing menu. ### Claim 18 (depends on 1) The mobile terminal of claim 1, wherein an execution of a specific main function is assigned to the first touch gesture and a sub-function dependent on the main function is assigned to the second touch gesture, and wherein the controller is further configured to execute the main function assigned to the first touch gesture and then execute the sub-function assigned to the second touch gesture. ### Claim 19 A method of controlling a mobile terminal, the method comprising: receiving, via a touchscreen of the mobile terminal, an input of a first touch gesture and a second touch gesture; storing, via a memory of the mobile terminal, a discrimination value for determining if the first or second touch gesture is by a touch pen; comparing, via a controller of the mobile terminal, an attribute of the first touch gesture with the discrimination value; receiving, via the controller, the first touch gesture as being from the touch pen when the attribute of the first touch gesture is within a predetermined value or range of the discrimination value; and executing, via the controller, an operation corresponding to the touch pen based on the first touch gesture being received as the touch pen. ### Claim 20 (depends on 19) The method of claim 19, wherein the first and second touch gestures are input to the touchscreen simultaneously or consecutively in a random order.
