For convenience of explanation, FIG. 1 will be described together.

The method of shaping a writing figure according to an embodiment of the present invention is started by generating ink information including information on each of the points constituting the stroke received from the user by the ink information generation unit 110 in operation S210. The stroke can be input from the user through the input device. 3A, when the stroke 310 is received from the user, the ink information generation unit 110 generates the ink coordinates of the points constituting the stroke 310, the view point coordinates, the end point coordinates, Order information, and the like can be generated. The ink information generating unit 110 may generate ink information on the stored strokes received from the user through a conventional method used in handwriting recognition. The ink information generation unit 110 may store the generated ink information in a memory.

Next, the graphic information generating unit 120 analyzes the geometric shape of the ink information and generates graphic information corresponding to the ink information (S220).

The graphic information generating unit 120 analyzes a geometric shape formed by the locus of the ink information to determine whether the geometric shape of the ink information is a shape such as a straight line, a triangle, a rectangle, a pentagon, a hexagon, Can be identified. The graphic information generating unit 120 can generate graphic type information that can identify the geometric shape formed by the locus of the ink information. For example, when analyzing the ink information for the stroke 310 shown in FIG. 3A, the graphic information generating unit 120 may generate the graphic type information by identifying that the geometric shape of the ink information is two straight lines .

The figure information generating unit 120 can generate the figure feature information based on the ink information and the figure type information. The shape feature information may include at least one of information such as, for example, view point coordinates, end point coordinates, intersection coordinates, vertex coordinates, center point coordinates, radius size and slope, and the like. For example, when analyzing the ink information for the stroke 310 shown in FIG. 3A, the graphic information generating unit 120 can generate graphic feature information including the view point coordinates and the end point coordinates of each of the two straight lines have. Since the figure feature information includes only the viewpoint coordinates and the endpoint coordinates of each of the two straight lines, when the figure is output based on the figure feature information, as shown in FIG. 3B, (320) may be output.

Next, the determination unit 130 determines application rules to be applied to the graphic feature information among rules stored in advance based on the graphic type information (S230). The pre-stored rules include rules for applying various geometries such as application rules for straight lines, application rules for triangles, application rules for rectangles, application rules for pentagons, application rules for hexagons, and application rules for ellipses . The determination unit 130 can determine the application rule of one of the above-described application rules based on the graphic type information. For example, when the stroke 310 shown in FIG. 3A is input, the determination unit 130 may determine an application rule for a straight line as an application rule to be applied to the graphic feature information. Exemplary application rules that can be applied to feature feature information are as follows.

1. Straight

For example, if the slope of the straight line is close to 0 ° or 180 °, for example, if the slope of the straight line is -5 ° to 5 ° or 175 ° to 185 °, the straight line is shaped as a horizontal line, For example, if the slope is near 90 or 270 degrees, for example, if the slope of the straight line is 85 to 95 or 265 to 275, the straight line can be normalized to a vertical line. Specifically, when the coordinates of the viewpoint are (x_1, y_1) and the coordinates of the end point are (x_2, y_2), the coordinates of the viewpoint are (x_1, (y_1 + y_2) / 2) In order to transform the coordinates into (x_2, (y_1 + y_2) / 2) and form the straight line as a vertical line, the coordinates of the start point are to be ((x_1 + x_2) / 2, y_1) / 2, y_2).

2. Triangle

The application rule for a triangle is to determine whether the triangle corresponds to an equilateral triangle, a right-angled isosceles triangle, a right triangle or an isosceles triangle, and then determine the triangle as a triangle, a right-angled isosceles triangle, It can be triangulated. 4 is a table showing application rules applied to a triangle in a method of styling a handwritten graphic according to some embodiments of the present invention. Specifically, in order to form a triangle, coordinates of three vertexes of the triangle are substituted into the conditional expression shown in FIG. 4 to judge whether or not the triangle corresponds to an equilateral triangle, a right-angled isosceles triangle, a right triangle or an isosceles triangle do. If the triangle is judged to be an equilateral triangle, a right-angled isosceles triangle, a right triangle or an isosceles triangle, by converting the length of the other two sides based on one side of the three sides of the triangle, the triangle can be represented by an equilateral triangle, a right angle isosceles triangle, Characteristics. &Lt; / RTI >

3. Rectangle

The application rule for a rectangle can be modified by changing the angle of the facing side and the length of the adjacent side. Specifically, when the difference between the angles of the opposing sides is smaller than a predetermined value, for example, 5 degrees or less, the angles of the opposing sides can be converted equally. For example, when the difference in the lengths of the neighboring sides is smaller than a preset value, for example, if l_2-l_1 < (l_2 + l_1) x 0.1, the lengths of neighboring sides can be converted equally.

4. Ellipse

The application rule for an ellipse is to shape the ellipse into a circle by changing the length of the major axis and the length of the minor axis according to the ratio of the length of the major axis and the length of the minor axis. For example, if the ratio of the length of the minor axis to the length of the major axis is greater than 0.9, the ellipse may be converted into a circle having the average value of the length of the major axis and the length of the minor axis as radii.

In the present specification, examples of application rules include rules for applying straight lines, triangles, squares, and ellipses, but the present invention is not limited thereto. The rules stored in advance may include various shapes such as polygons, sectors, parabolic lines, Lt; RTI ID = 0.0 > rule. &Lt; / RTI >

According to some embodiments of the present invention, the application rules may be changed by the user's settings. By changing the application rules, the criteria for shaping a figure can be raised or lowered. For example, constants such as 1/20 or 10, as shown in the table of FIG. 4, may be changed through the user's setting, where the probability that the figure will be shaped increases as the constant increases and the probability that the figure will be shaped Lower. When changing the application rules, it may be difficult for the user to directly select the constants, so a user interface may be provided for easily changing the application rules. For example, the user can provide a user interface so that the user can select one of the steps 1 to 5 as a criterion for shaping the figure, and when the user selects the step 1, the criterion for shaping the figure increases, You can change the application rules so that the standard for formatting the lower graphic is lowered. The advantageous effect of the present invention in which the shape figure information can be calculated accurately by reflecting the intention of the user more accurately can be obtained by changing the rules stored in advance as the standard of the standardization as described above.

Next, the calculating unit 140 calculates shape information that is formed by applying the application rule to the graphic feature information (S240). The formatted shape information indicates the shape feature information changed through the application rule determined by the determination unit 130. FIG. The calculating unit 140 can calculate the figure information that has been formalized by substituting the figure feature information into the application rule. For example, the calculator 140 may apply the above-described rule for the straight line to the figure feature information corresponding to the figure 320 including the two straight lines shown in FIG. 3B, It is possible to calculate the formatted figure information for the formed figure 330 including the horizontal line and the vertical line shown in 3c.

Next, the output unit 150 outputs the figure shaped in accordance with the formed figure information (S250). The shaped figure may be, for example, a figure such as a horizontal line, a vertical line, a right triangle, an isosceles triangle, a trapezoid, a parallelogram, a regular polygon or a circle. The output unit 150 may output the formatted graphics based on information such as viewpoint coordinates, endpoint coordinates, intersection coordinates, vertex coordinates, center point coordinates, radius size, slope, and the like included in the formatted graphics information. For example, the output unit 150 may output the shaped figure 330 shown in FIG. 3C when the stroke 310 shown in FIG. 3A is received.

As described above, the advantageous effect of the present invention is obtained that the input figure can be corrected to the formatted figure by reflecting the user's intention by applying the application rule suitable for the shape of the figure input by the user.

According to some embodiments of the present invention, the query unit may simultaneously output a figure corresponding to the figure information and a shape figure corresponding to the shape figure information through the output unit 150, and then output the shape figure to the user You can also ask whether or not. For example, the query unit may simultaneously output the graphic 320 and the formatted graphic 330 through the output unit 150, and then output the graphic 320 to the user or output the formatted graphic 330 Can be queried. As described above, it is possible to provide a user interface by which a figure inputted by a user and a figure shaped at the same time are simultaneously output, so that a user can select a figure to be inputted by comparing the figure inputted with a figure, An advantageous effect is obtained.
