reference will now be made in detail to the preferred embodiments of the present invention , examples of which are illustrated in the accompanying drawings . referring to fig1 , the mobile terminal 100 comprises a fingerprint identification unit 110 to detect position information of a user &# 39 ; s finger through identification of a user &# 39 ; s fingerprint in a sweep - type mode . the position information of the user &# 39 ; s finger is computed using direction data of the fingerprint extracted using the fingerprint unit 110 . detection and use of the direction data of the fingerprint will be described below . the mobile terminal 100 further comprises a user interface 120 for receiving a selection of control modes from a user using the position information of the user &# 39 ; s finger . the user interface 120 comprises a key input part 122 receiving operational signals from a plurality of buttons on the mobile terminal . a mode switching part 121 determines whether the fingerprint is used for a fingerprint identification mode , or a direction data read mode . if the mode switching part 121 is in the direction data read mode , fingerprint direction data may be further inputted . in one example , the control mode may be combined with a mouse mode ( e . g ., a mouse pointer moves across the screen ) and a screen mode ( e . g ., a window on the screen is moved across a fingerprint image ). the mode switching part 121 may select separately a first mode switching part having a fingerprint identification mode or the direction data read mode , and a second mode switching part having a pre - determined control mode . a controller 150 performs control operations according to a selection of the control mode through a user interface 120 with reference to the information of the position of the user &# 39 ; s finger detected utilizing the fingerprint identification unit 110 . a display unit 130 displays results performed utilizing the controller 150 . a transceiver unit 140 performs general communication functions within the mobile terminal . in accordance with one aspect of the invention , a user positions a finger on the fingerprint identification unit 110 so that part of a finger &# 39 ; s surface touches a sensor , whereby a photographed image is inputted to the fingerprint identification unit 110 . it should be noted that the inputted image of the fingerprint , in this example , maybe a partial image of the fingerprint . initial image data of the fingerprint is labeled , in this example , as image f ( 0 ). features of the fingerprint are extracted from the image data and stored as comparison features . during a sweep operation , a user moving his finger across the fingerprint identification unit 110 creates a two - dimensional image of his fingerprint . frames of partial fingerprint images , as a function of time , are photographed and inputted consecutively into the fingerprint identification unit 110 . a series of the frames that are consecutively inputted are represented by the image frame series represented by f ( 1 )˜ f ( m )˜ f ( m ). finger sweeps are , for example , performed over a time interval between the frames , which time is sufficiently short and creates considerable overlap of image photographs between adjacent frames . in other words , a finger sweeps across the sensor at a rate such that a value of a movement vector of the fingerprint may be accurately processed utilizing overlapped image photographs . in this example , if a frame f ( m ) is inputted , f ( m - 1 ), i . e ., a corresponding portion between a previous frame and a present frame is explored so that a movement vector may be computed for relative finger motion . if a number of corresponding points between the previous frame and the present frame is smaller than a pre - determined minimum required value in computing the movement vector , the user may be requested to re - input the image . the direction data of the fingerprint is computed as the image frame is moved across the fingerprint image , section by section , using the process described above . movement of the finger , in one example , result in a sweep pattern created utilizing a set of movement vectors across the fingerprint image . using the above process , it is possible to detect information for movement of the user &# 39 ; s finger for creating a control signal for a mobile terminal or performing fingerprint identification . thus , the present invention may be applied to numerous consumer and technology fields capable of utilizing information of a user &# 39 ; s finger motion and user identification . referring to fig1 and 2 , the control mode maybe set to the mouse mode using the mode switching part 121 . the mouse pointer is moved and displayed on the display unit 130 to display the detected position information of the user &# 39 ; s finger . setting the control mode to the mouse mode results in direction data information of the fingerprint being detected . in the mouse mode , identification information of the user &# 39 ; s finger is not performed . the mobile terminal , in the mouse mode , allows the mouse pointer to be moved in accordance with movement information of the user &# 39 ; s finger . referring to fig2 , the mouse pointer displayed on the display unit 130 is moved along a movement direction of the user &# 39 ; s finger designated utilizing the direction data information . if the mobile terminal 100 operates in the mouse mode as described above , a menu list may be used for selecting functions of the mobile terminal 100 or a keypad to be displayed on the display unit 130 . in this case , the user moves the mouse pointer to a desired position by moving his finger on the fingerprint identification unit 110 . movement of the user &# 39 ; s finger is detected and a selected operation is performed using a click operation . during the click operation , a mouse pointer selects the menu list or a keypad in accordance with extracted position information of the user &# 39 ; s finger . the click operation may be performed utilizing various methods , such as by strongly pressing the finger for a pre - determined period of time on the sensor to change the mouse pointer position or removing the finger from the sensor temporarily to maintain the mouse pointer position . if the menu list or the keypad is displayed on the display unit 130 , a user selects the desired menu or keypad by moving his finger on the fingerprint identification unit 110 . the on - screen menu reduces the cost of a mobile terminal because an additional keypad is not required to be installed on the mobile terminal . referring to fig1 and 3 , if the control mode selected is the window mode , the window on the screen of the display unit 130 may be placed over a portion of the fingerprint image in accordance with the direction data . more specifically as shown in fig3 , a map displayed on the display unit 130 may be moved , for example in its entirety , in accordance with the movement direction of the user &# 39 ; s finger . in summary , using the above - described method , the user may conveniently move an image , such as the map displayed on the display unit 130 , to a desired direction such as up , down , right , and left using finger motion . the above - described method supports current trends whereby high quality images are supported by the mobile terminal . referring to fig1 and 4 , if the control mode selected through the user interface 120 is a drawing mode , a line may be drawn on the display unit 130 according to the direction data of the fingerprint . a picture , using the above drawing process , may be drawn . if the user moves a finger on the fingerprint identification unit 110 , a line or a picture that corresponds to movement direction may be drawn on the display unit 130 according to the movement information of the user &# 39 ; s finger detected utilizing the fingerprint identification unit 110 . as described above , according to the mobile terminal and the operating method therefor , it is possible to provide a variety of useful application functions to the user using the information of the position of the user &# 39 ; s finger based on the direction data of the fingerprint detected . the fingerprint identification unit performs a user verification function based on the fingerprint identification . it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention . thus , it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents .
