Abstract

A method for controlling a figure based on a touch includes recognizing a figure which is input by handwriting on a touch screen, displaying one or more variable points to which a controlling function of a figure is mapped on a trajectory of the recognized figure, detecting a touch input that selects one of the variable points, determining whether a controlling function execution request of the recognized figure is detected based on at least one of a pressure information and a touch gesture information corresponding to the detected touch input, and executing the controlling function of the figure corresponding to the selected variable points when the controlling function execution request is detected.

Claims

1. A method for controlling a figure, the method comprising:

recognizing a figure which is input by handwriting on a touch screen;

displaying one or more variable points to which a controlling function of a figure is mapped on a trajectory of the recognized figure;

detecting a touch input that selects one of the variable points;

determining whether a controlling function execution request of the recognized figure is detected based on at least one of a pressure information and a touch gesture information corresponding to the detected touch input; and

executing the controlling function of the figure corresponding to the selected variable points when the controlling function execution request is detected.

2. The method of claim 1, wherein executing the controlling function of the figure comprises:

executing a controlling function command of a figure which is mapped to the selected variable point; and

executing at least one of an addition, a deletion, a shape change, a style change, an effect change, a color change, a size change, and a length change function of the recognized figure according to the execution.

3. The method of claim 1, wherein determining whether the controlling function execution request is detected comprises:

detecting a touch gesture corresponding to the touch input; and

detecting the controlling function execution request when the touch gesture corresponds to a preset function execution gesture.

4. The method of claim 1, wherein determining whether the controlling function execution request is detected comprises:

detecting a touch pressure information corresponding to the touch input;

detecting the touch gesture when a touch gesture input movement generates within a certain period of time after detecting the touch pressure; and

detecting the controlling function execution request when the touch gesture corresponds to a preset functional execution gesture.

5. The method of claim 1, wherein executing the controlling function of the figure comprises changing the number of the variable points according to a shape of the figure in which the operational function is executed to output.

6. The method of claim 1, wherein executing the controlling function of the figure comprises:

outputting a first changed figure according to a first option of the controlling function in response to a first touch gesture when the first touch gesture is input;

outputting a second changed figure according to a second option of the controlling function in response to a second touch gesture when the second touch gesture is input; and

outputting a third changed figure according to a third option of the controlling function in response to a third gesture when the third touch gesture is input.

7. The method of claim 1, further comprising:

releasing a mark of the variable point when a touch generates from an external area of the recognized figure.

8. The method of claim 1, further comprising:

detecting a touch gesture passing through a part of the recognized figure in an external area of the recognized figure;

splitting and displaying the recognized figure according to a touch gesture in response to the detected touch gesture; and

executing a function of deleting the selected area when a deletion function execution request gesture is detected with respect to a touch selecting one area among the split area of the figure.
