Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object existing in the vicinity using the force of an electromagnetic field or infrared rays without mechanical contact. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or in the vicinity of the touch screen.

The drag input screen 515 displayed with different colors and shades on the virtual keyboard 410 illustrated in FIG. 5 is only an example, and if the user can input a drag to designate a deletion range, Various user interface (UI) known at the time of filing of the present invention may be used, and since this point is a known technique at the time of filing of the present invention, detailed description thereof will be omitted.

3, 7 and 8, when the mobile terminal 100 senses the drag input from the first point 701 to the second point 702 on the drag input screen 515 in step S318, step In S320 , the mobile terminal 100 may display the deletion area based on the cursor 430 in the content input window 420 corresponding to the displacement from the first point 701 to the second point 702 .

Hereinafter, it is assumed that the horizontal direction of the mobile terminal 100 is the X-axis and the vertical direction is the Y-axis.

Referring to FIG. 7 , the mobile terminal 100 calculates the displacement of the X-axis component from the first point 701 to the second point 702, and responds to the calculated displacement in the content input window 420. The deletion area 704 may be displayed based on the cursor 430 .

For example, if the specified weight is 2, the mobile terminal 100 multiplies the displacement from the first point 701 to the second point 702 of the drag input screen 515 by the user by the specified weight and doubles it. may calculate the weighted displacement of , and display the deletion area (eg, 814 of FIG. 8 ) in the content input window 420 corresponding to the calculated weighted displacement. In this case, there is an advantage that the user can more quickly designate a deletion area (eg, 814 in FIG. 8 ). In addition, if there is no designated weight, when the user wants to delete an entire line from the content input window 420, dragging is required from the right end to the left end of the drag input screen 515, so the drag start position is limited. There may be problems with receiving . However, when the designated weight is 2, the user only needs to drag by 1/2 in the X-axis direction of the drag input screen 515, so there is an advantage that the drag start position on the drag input screen is less limited.

The weight specified in the above-described embodiment may be variously specified according to the sizes of the mobile terminal 100, the content input window 420, and the drag input screen 515 in the X-axis direction and the Y-axis direction, and furthermore, the X-axis component It will be apparent to those skilled in the art in light of the technical spirit of the present invention that the and Y-axis components may be designated differently.

Also, according to an embodiment of the present invention, the specified weight may be increased in units of the specified displacement as the displacement magnitude from the first point to the second point increases.

For example, it will be described with reference to FIG. 9 . According to an embodiment of the present invention, the mobile terminal 100 may apply a weight 1 designated when calculating the weighted displacement with respect to the drag from the first point 901 to the second point 902 , and the first point 901 . ) to the third point 903 further spaced apart from each other, a weight of 2 designated when calculating the weighted displacement may be applied. In this case, as described above, there is an advantage that the user can selectively have a sense of homogeneity and speed when designating a deletion area in the content input window. The weight value illustrated in FIG. 9 is only an example, and as mentioned above, it varies depending on the size of the mobile terminal 100, the content input window 420, and the drag input screen 515 in the X-axis direction and the Y-axis direction. In light of the technical spirit of the present invention, it will be apparent to those skilled in the art that it may be designated to be specific, and furthermore, the X-axis component and the Y-axis component may be designated differently.

Referring back to FIG. 3, in step S322, the mobile terminal 100 deletes the input content included in the deletion area displayed in the content input window 420 when sensing the user's touch release on the drag input screen 515, The rest can be displayed to the user.

So far, a method of controlling the mobile terminal 100 according to an embodiment of the present invention has been described with reference to FIGS. 3 to 11 .

Although not shown in FIGS. 3 to 11 , the mobile terminal 100 identifies the contents included in the deletion area (eg, 704 in FIG. 7 ) in the contents input window 420 from the contents not included in the deletion area. It will be apparent to those skilled in the art in light of the technical spirit of the present invention that it may be indicated differently.

In addition, in FIGS. 3 to 11 , as an input for calling the drag input screen 515 , a long touch that is a touch longer than a specified time for the delete key ( 412 in FIG. 4 ) of the virtual keyboard 410 is sensed. Although the description has been made on the assumption that this is an example, various inputs may be designated.

For example, one or two or more inputs may be pre-specified by using a component included in the input unit ( 120 in FIG. 1 ) and the sensing unit ( 140 in FIG. 1 ), and the mobile terminal 100 detects these inputs. In this case, the drag input screen 515 may be displayed.

For example, as illustrated in FIG. 10 , when the mobile terminal 100 senses a touch on the delete key 412 of the virtual keyboard 410 , it controls the display 151 to A boundary line 1002 designated on the left can be displayed. And when the delete key 412 senses a drag that crosses the boundary line 1002, the mobile terminal 100 may display a drag input screen 515 as illustrated in FIG. 11 . Hereinafter, it is assumed that drag is made to the first point 1011 beyond the boundary line 1002 in the present embodiment. Referring to FIG. 11 , the mobile terminal 100 senses the drag from the first point 701 to the second point 702 on the drag input screen 515 to calculate the displacement, and accordingly the content input window 420 . Since the display of the deletion area ( 1014 in FIG. 14 ) in FIG. 14 has been previously described with reference to FIGS. 3 to 9 , a redundant description thereof will be omitted. According to the embodiment illustrated in FIGS. 10 to 11 , the user can perform deletion corresponding to one by touching the deletion key 412 or designate the deletion area by naturally dragging over the boundary line 1002 . There are advantages.

12 and 13 are diagrams for explaining the deletion process in the right direction of the cursor according to another embodiment of the present invention.

According to the control method of the mobile terminal 100 according to another embodiment of the present invention, as illustrated in FIG. 12 , the mobile terminal 100 senses a touch on the delete key 412 of the virtual keyboard 410 . In this case, the mobile terminal 100 may control the display 151 to display the right-direction delete key 1210 on the upper side of the delete key 412 . And, as illustrated in FIG. 13 , when the mobile terminal 100 senses an upper drag from the delete key 412 to the right delete key 1210 , the mobile terminal 100 displays the content input window 420 . The deletion area 1314 may be displayed in the right direction in a unit (eg, one letter or one word) that is predetermined based on the cursor 430 . In addition, when the mobile terminal 100 senses the touch release, after deleting the content included in the deletion area 1314 , the remaining input content may be displayed on the content input window by controlling the display 151 . Accordingly, according to another embodiment of the present invention, there is an advantage that deletion can also be performed in the right direction based on the cursor.

Although not shown in FIG. 13 , the mobile terminal 100 displays a predetermined boundary line between the delete key 412 and the right delete key 1210 to guide the above-described upward drag. It will be apparent to those skilled in the art in light of the technical idea.

The above-described method for controlling the mobile terminal 100 according to the embodiment of the present invention may be implemented as a computer-readable code on a computer-readable recording medium. Computer-readable recording media include all types of recording media in which data that can be decoded by a computer system are stored. For example, there may be read only memory (ROM), random access memory (RAM), magnetic tape, magnetic disk, flash memory, optical data storage device, and the like. In addition, the computer-readable recording medium can be distributed to a computer system connected through a computer communication network, and stored and executed as code that can be read in a distributed manner.

Although the above has been described with reference to the embodiments of the present invention, those of ordinary skill in the relevant technical field variously modify the present invention within the scope not departing from the spirit and scope of the present invention described in the following claims. And it will be easily understood that it can be changed.
