controlling a touch sensitive display device according to one embodiment of the present specification may include the steps of displaying a graphic user interface including a first area of a virtual keyboard and a second area of a digital content containing at least one word, detecting a first contact from the first area, displaying and moving a word-selecting interface according to the first contact moving from the first area to the second area, displaying the at least one word overlapped by the word-selecting interface in the digital content as a soft button, detecting a second contact from the soft button, and inputting a word corresponding to the soft button from which the second contact is detected into a text input box. ## Claims ### Claim 1 A touch sensitive display device, comprising: a display unit configured to display a graphic user interface; a sensor unit configured to sense a contact with the display unit; and a controller configured to control the display unit and the sensor unit, wherein the graphic user interface comprises a first area of a virtual keyboard and a second area of a digital content containing at least one word, wherein the controller: detects a first contact in the first area; displays and moves a word-selecting interface according to the first contact moving from the first area to the second area, displays the at least one word overlapped by the word-selecting interface in the digital content as a soft button, respectively, detects a second contact from the soft button and inputs the word corresponding to the soft button from which the second contact is detected into a text input box. ### Claim 2 (depends on 1) The touch sensitive display device of claim 1, wherein the control unit converts the at least one word overlapped by the word-selecting interface in response to a position from which the first contact is detected in the virtual keyboard of the first area and wherein the controller displays the converted at least one word in the soft button, respectively. ### Claim 3 (depends on 2) The touch sensitive display device of claim 2, wherein the controller converts the at least one word overlapped by the word-selecting interface in response to a key of the virtual keyboard displayed in the position from which the first contact is detected and wherein the controller displays the converted at least one word in the soft button, respectively. ### Claim 4 (depends on 2) The touch sensitive display device of claim 2, wherein if the second contact is detected from the soft button, the controller inputs the converted word displayed in the soft button into the text input box. ### Claim 5 (depends on 1) The touch sensitive display device of claim 1, wherein if the first contact is detected from a language shift key area of the virtual keyboard of the first area, the controller translates the at least one word overlapped by the word-selecting interface and wherein the controller displays the translated word in the soft button, and wherein the controller inputs the translated word into the text input box. ### Claim 6 (depends on 1) The touch sensitive display device of claim 1, wherein if the first contact is detected from a letter key area of the virtual keyboard of the first area, the controller searches for the word starting with the letter in the digital content and wherein the controller displays the searched word as the soft button. ### Claim 7 (depends on 1) The touch sensitive display device of claim 1, wherein if the first contact is detected from a number key area of the virtual keyboard of the first area, the controller preferentially displays the word of high frequency of use in the digital content as the soft button. ### Claim 8 (depends on 1) The touch sensitive display device of claim 1, wherein if the first contact is detected from a shift key area of the virtual keyboard of the first area, the controller displays the at least one word overlapped by the word-selecting interface in the soft button in a manner of converting to an upper case and wherein the controller inputs the word displayed in the upper case into the text input box. ### Claim 9 (depends on 1) The touch sensitive display device of claim 1, wherein the controller activates the word-selecting interface when the first contact passes by a boundary of the first area and the second area. ### Claim 10 (depends on 1) The touch sensitive display device of claim 1, wherein the controller deactivates the word-selecting interface when the first contact is released. ### Claim 11 (depends on 1) The touch sensitive display device of claim 1, wherein the word-selecting interface overlaps one or more text lines. ### Claim 12 (depends on 11) The touch sensitive display device of claim 11, wherein the sensor unit senses a third contact for controlling a size of the word-selecting interface and wherein the controller controls the size of the word-selecting interface according to the sensed third contact. ### Claim 13 (depends on 1) The touch sensitive display device of claim 1, wherein if duplicated word among the words overlapped by the word-selecting interface exists, the controller displays one of the duplicated words as the soft button. ### Claim 14 (depends on 1) The touch sensitive display device of claim 1, wherein the controller selectively displays the word overlapped by the word-selecting interface in the digital content as the soft button according to a part of speech of the word. ### Claim 15 (depends on 14) The touch sensitive display device of claim 14, wherein the controller selectively displays the word that the part of the speech is noun among the words overlapped by the word-selecting interface in the digital content as the soft button. ### Claim 16 (depends on 15) The touch sensitive display device of claim 15, wherein the controller further displays a relation word for the displayed noun as the soft button. ### Claim 17 (depends on 1) The touch sensitive display device of claim 1, wherein the controller indicates the at least one word overlapped by the word-selecting interface in a manner of highlighting. ### Claim 18 (depends on 1) The touch sensitive display device of claim 1, wherein the word-selecting interface is displayed in the form of a transparent bar or a semi-transparent bar. ### Claim 19 (depends on 1) The touch sensitive display device of claim 1, wherein the controller deactivates a hyperlink of the at least one word overlapped by the word-selecting interface. ### Claim 20 (depends on 1) The touch sensitive display device of claim 1, wherein the sensor unit delivers the sensed contact to the controller in a manner of converting to an electrical signal and wherein the controller detects the contact based on the electrical signal. ### Claim 21 A method of controlling a touch sensitive display device, comprising the steps of: displaying a graphic user interface including a first area of a virtual keyboard and a second area of a digital content containing at least one word using a display unit; detecting a first contact from the first area using a sensor unit; displaying and moving a word-selecting interface according to the first contact moving from the first area to the second area using a controller; displaying the at least one word overlapped by the word-selecting interface in the digital content as a soft button using the controller; detecting a second contact from the soft button using the sensor unit; and inputting the word corresponding to the soft button from which the second contact is detected into a text input box using the controller.
