Method for inserting a table into a document using a touch screen [0002]

The present invention relates to a method for inserting a table into a document using a touch screen, and more particularly, to a method for easily inserting a table composed of rows and columns into a document or editing an inserted table using multi-touch.

BACKGROUND ART [0002] Devices such as computers, personal digital assistants (PDAs), and mobile communication terminals typically use physical keypads for user interfacing. That is, since conventional devices such as a computer, a personal digital assistant, and a mobile communication terminal input text, data, commands, etc. through a physical keypad.

However, such a user interfacing device has been increasingly diversified. In recent years, a touch screen panel (TSP) has been used for inputting object-oriented user information in a user interfacing method.

In this way, the user information input through the touch-screen-panel significantly increases the convenience of the user as compared with the input of the user information through the existing keypad by inputting the desired information in the same manner as the user writes on paper.

In addition, the touch-screen-panel may provide a variety of keypads using a narrow space by providing a soft button including a different key-set according to an operation mode or user's selection information. Accordingly, such a touch-screen-panel is more advantageously used as an input device of a small terminal such as a PDA or a mobile communication terminal.

Typically, graffiti, a virtual keyboard (e.g., a soft button), and a menu command are used for inputting characters in the device having the touch-screen-panel. At this time, the character input method using the grapheme is a method of designating a character to be input easily in a touch-pad (i.e., a grapter) and displaying the corresponding character by the input of the grapter .

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

1 is a block diagram illustrating a configuration of a user terminal including a touch screen according to an embodiment of the present invention. Hereinafter, a configuration of a user terminal including a touch screen according to an embodiment of the present invention will be described in detail with reference to FIG.

Referring to FIG. 1, a user terminal includes a control unit, an input unit, a display unit, a storage unit, and a camera unit. It goes without saying that other configurations other than the above-described configuration may be further included. Further, the input unit and the display unit can be configured in one configuration.

The storage unit 102 is divided into a ROM area in which control program data for controlling the operation of the user terminal is stored and a RAM area in which data generated in the control operation of the user terminal is temporarily stored. In addition, the storage unit 102 stores information on a table inserted in a document proposed by the present invention. For example, the storage unit 102 stores information on the size of a cell composed of rows and columns constituting a table.

The display unit 104, which is one of the user interface units, displays screen data generated during application execution, and displays the key operation state and function setting information of the user. In association with the present invention, the display unit 104 is formed integrally with the input unit. That is, the present invention inputs necessary information using a touch screen and outputs necessary information.

The camera unit 106 converts light (light) input through the camera lens into digital data through a sensor. The sensor may include a charge coupled device (CCD), a complementary metal-oxide semiconductor (CMOS), or the like. The camera unit 414 may include a camera sensor for converting the input optical signal into an electrical signal and a signal processor for converting the analog image signal photographed by the camera sensor into digital data. The signal processing unit may be implemented as a digital signal processor (DSP). The camera sensor and the signal processing unit may be integrally formed, or separately. The camera unit 106 may be implemented in one or more than one, depending on the provision of the terminal.

The control unit 108 controls the operation of each component constituting the user terminal. In particular, the control unit 108 reads a document stored in the storage unit and displays the document on the display unit 104, inserts a table into the document using the touch information input through the input unit 110, or edits the inserted table . A method of inserting the table into the document or editing the inserted table in the control unit 108 will be described later.

FIG. 2 illustrates a method of inserting a table into a document using a touch screen constituting a user terminal according to an embodiment of the present invention. Hereinafter, a method of inserting a table into a document using a touch screen constituting a user terminal according to an exemplary embodiment of the present invention will be described in detail with reference to FIG.

According to FIG. 2, the method of inserting a table into a document using the touch screen differs depending on the format of the table. A table having at least two rows and at least one row, and a table having at least two rows and columns. Hereinafter, a method of inserting a table into a document according to the format of the table will be described in order.

First, to create a table having one row and at least two columns, the user touches two points such that the coordinate values of the vertical axis (column direction) on the touch screen are the same and the coordinate values of the horizontal axis (row direction) are different . Then, the user drags the touch point so that the gap between the two touch points becomes larger. For example, if the location information of two points touched on the existing touch screen is (2,3), (5,3), drag the two touch points to create a table having one row and at least two columns The position information of the two touch points is set to (1,3), (6,3). That is, the distance between two points of the existing touch is 3, while the distance between two points after the drag is 5. As the distance between two touch points increases, a table having one row and at least two columns is generated. Of course, the number of columns included in the generated table is proportional to the size of the increased interval. For this, the user can set the number of columns included in the table corresponding to the size of the interval that is increased in advance. That is, it is possible to preset the number of columns to increase by 1 every time the size of the interval increases by one. In addition, the number of columns included in the table generated in various manners can be adjusted.

Next, in order to generate a table having at least two rows and one column, the user touches two points so that the coordinate values of the horizontal axis (row direction) on the touch screen are the same and the coordinate values of the vertical axis do. Then, the user drags the touch point so that the gap between the two touch points becomes larger. For example, if the location information of two points touched on the existing touch screen is (3, 2), (3, 5), drag the two touch points to create a table having at least two rows and one column The positional information of the two points touched has values of (3, 1) and (3, 6). That is, the distance between two points of the existing touch is 3, while the distance between two points after the drag is 5. As the distance between two touch points increases, a table having at least two rows and one column is generated. Of course, the number of rows included in the generated table is proportional to the size of the increased interval. To this end, the user can set the number of rows included in the table corresponding to the size of the interval that is increased in advance. That is, the number of rows can be set to be increased by one every time the size of the interval increases by one. In addition, the number of rows included in the table generated in various ways can be adjusted.

인 반면, 드래그 이후 두 지점의 간격은

가 된다. 이와 같이 터치한 두 지점의 간격이 증가됨으로 인해 적어도 두 개의 행과 열을 갖는 표가 생성한다. 물론 증가된 간격의 크기에 비례하여 생성되는 표에 포함되는 행과 열의 개수가 달라진다. 이를 위해 사용자는 미리 증가되는 간격의 크기에 대응되는 표에 포함되는 열의 개수를 설정할 수 있다. 즉, 간격의 크기가 1증가할 때마다 열 또는 행의 개수가 1 증가하도록 미리 설정할 수 있다. 이외에도 다양한 방식으로 생성되는 표에 포함되는 열의 개수를 조절할 수 있다. 일예로 일반적으로 표에 포함되는 셀의 가로 방향의 길이가 세로 방향의 길이보다 크다. 따라서 이를 반영하여 가로 방향의 길이와 세로 방향의 길이가 상이한 셀을 갖는 표를 생성할 수 있다.Finally, to create a table with at least two rows and at least two columns, the user touches two points such that the coordinate values in the vertical axis (column direction) on the touch screen and the coordinate values in the horizontal axis (row direction) are different. Then, the user drags the touch point so that the gap between the two touch points becomes larger. For example, if the location information of two points touched on the existing touch screen is (3, 3), (5, 5), drag two touch points to create a table having at least two rows and And the position information of the two points has values of (2, 2) and (6, 6). That is, the distance between two points of the existing touch

While the distance between the two points after the drag is

. As the distance between two points touched is increased, a table having at least two rows and columns is generated. Of course, the number of rows and columns included in the generated table is proportional to the size of the increased interval. For this, the user can set the number of columns included in the table corresponding to the size of the interval that is increased in advance. That is, the number of columns or rows may be increased by 1 every time the size of the interval increases by one. In addition, the number of columns included in the table generated in various manners can be adjusted. For example, the length of the cell in the horizontal direction is generally greater than the length in the vertical direction. Accordingly, a table having cells having different lengths in the horizontal direction and the vertical direction can be generated by reflecting this.

FIG. 3 illustrates a method for adding rows or columns to a generated table according to an embodiment of the present invention. Hereinafter, a method of adding rows or columns to a generated table according to an embodiment of the present invention will be described in detail with reference to FIG.

In addition, the distance between the rows and columns constituting the table can be set differently according to the distance between the two points of the first touch. That is, the distance between the first touch and the first touch may be set to be proportional to the interval between the rows and the columns constituting the table.

There are two ways to insert additional rows or columns into a table. There are two ways to add rows or columns to a table that consists of multiple rows or columns, or to add rows or columns to the end of a table that consists of existing rows or columns. Hereinafter, a method of adding a row or a column to a table composed of a plurality of rows or columns will be described first.

3, a table composed of three rows and four columns is shown. Let's look at a case where we want to add one row between the second row and the third row. In this case, the user touches one point of the second row and one point of the third row. Then, the user drags the touch position in the vertical axis direction so as to increase the interval between the touched points. One row is added between the second row and the third row through the above-described process. Of course, the number of rows to be added differs depending on the size of the increased interval of the touched point. In addition, even if a column constituting a table is to be added, it can be added in the same manner.

Next, let's see how to add columns or rows to the end of the table. As described above, Fig. 3 shows a table composed of three rows and four columns. If the user wishes to add a fourth row to the bottom of the third row, the user touches one point on the third row and one point on the bottom of the third row (outside the table). Then, the user drags the touch position in the vertical axis direction so as to increase the interval between the touched points. Through the above-described process, the fourth row is added to the bottom row of the third row. Of course, the number of rows to be added differs depending on the size of the increased interval of the touched point. In addition, even if a column constituting a table is to be added, it can be added in the same manner.

FIG. 4 illustrates a scheme for constructing a table according to an embodiment of the present invention and adding rows or columns within a specific cell. Hereinafter, a method of adding a row or a column in a cell constituting a table according to an embodiment of the present invention will be described in detail with reference to FIG.

4, a table composed of three rows and four columns is shown. Hereinafter, a case will be described in which one row is to be added inside the cells of the second row and the second column. In the above case, the user touches two points inside the cell. Then, the user drags the touch position in the vertical axis direction so as to increase the interval between the touched points. A row is added inside the cell through the above-described process. Of course, the number of rows to be added differs depending on the size of the increased interval of the touched point. In addition, when a column is to be added to a cell, it can be added in the same manner. Of course, when at least two rows and at least two columns are added to a cell, the touch point may be increased by touching two points in an oblique direction as shown in FIG.

FIG. 5 illustrates a method of adding a row or a column in a specific cell constituting a table according to another embodiment of the present invention. Hereinafter, a method of adding a row or a column in a specific cell constituting a table according to an embodiment of the present invention will be described with reference to FIG.

According to Fig. 5, a table composed of three rows and four columns is shown. Hereinafter, a case will be described in which one row is to be added inside the cells of the second row and the second column. In the above case, the user touches one point in the cell and drages in the horizontal axis direction. Then tap (tap) a point within the cell by the number of rows to be added. That is, when the area inside the cell is relatively smaller than the number of the rows to be added in the cell, the row can be efficiently added to the inside of the cell by tapping the number of rows to be added as described above.

If at least one row is to be added to at least two consecutive cells, the number of rows to be added is tapped after dragging at least two consecutive cells. That is, if two rows are to be added to each of the cells constituted by the second row and the second column, and the cells formed by the third row and the second column, the user may touch the cells formed by the second row and the second column Drag into the cell consisting of the third row and the second column. Then, tap (tap) any one of the cells consisting of the second row and the second column or inside the cell composed of the third row and the second column. Through this process, two rows are added to each cell composed of the second row and the second column, and each cell composed of the third row and the second column.

FIG. 6 illustrates a case where an area is divided into an oblique line in a cell according to an embodiment of the present invention. Hereinafter, a case where an area is divided into oblique lines in a cell according to an embodiment of the present invention will be described in detail with reference to FIG.

In order to divide the area into an oblique line inside the cell, the user keeps the state of touching the two corners of the cell to be divided for the set time. In this way, when a user touched two points of a corner to be divided and held the set time, a line connecting the corner is formed inside the corresponding cell. As described above, the present invention generates a slanting line dividing the inside of the cell using the touching time. In addition, the inside of the cell is divided in various ways.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the present invention .
