Abstract

The disclosure is a method and device for drawing a figure in correspondence to an input made with a first input tool and a second input tool to the terminal including an input unit capable of detecting physical touch and electrical input includes detecting a touch input made with the first and second input tools to the input unit; displaying at least one line movable according to contact points of the detected input on a display unit of the terminal; receiving a selection command based on the electrical input made with at least one of the first and second input tools; and displaying one of the at least one line as the line of which at least one of length and direction is fixed.

First claim

What is claimed is:

1. A method for drawing a figure on a screen of an electronic device, the method comprising:
displaying a guide UI item comprising at least one line and an auxiliary information including an angle measurement related to the guide UI item, in response to receiving a first user input, wherein the auxiliary information is displayed at least partially inside the guide UI item;
receiving a second user input for changing a direction of the guide UI item while the guide UI item is displayed with the angle measurement of the guide UI item;
displaying the auxiliary information with a changed angle measurement of the guide UI item in response to the second user input;
receiving a third user input while the guide UI item is displayed; and
displaying a first line, in response to the third user input based on the guide UI item.

2. The method of claim 1 , wherein the at least one line defines a bounded region on the screen, and
the angle measurement is displayed inside the bounded region.

3. The method of claim 1 , wherein the second user input comprises a touch input and the third user input comprises a touch input.

4. The method of claim 1 , wherein the second user input comprises multi touch gestures on the guide UI item and touch movement gestures to other positions.

5. The method of claim 1 , wherein the first line is displayed on at least part of the at least one line of the guide UI item.

6. An electronic device comprising:
a display;
at least one processor operably coupled to the display; and
memory operably coupled to the at least one processor and the display, the memory storing a plurality of instructions, wherein execution of the plurality of instructions by the at least one processor cause the at least one processor to perform a plurality of operations comprising:
displaying a guide UI item comprising at least one line and an auxiliary information including an angle measurement related to the guide UI item, in response to receiving a first user input, wherein the auxiliary information is displayed at least partially inside the guide UI item;
receiving a second user input for changing a direction of the guide UI item while the guide UI item is displayed with the angle measurement of the guide UI item;
displaying the auxiliary information with a changed angle measurement of the guide UI item in response to the second user input;
receiving a third user input while the guide UI item is displayed; and
displaying a first line, in response to the third user input based on the guide UI item.

7. The electronic device of claim 6 , wherein the at least one line defines a bounded region on the display, and
the angle measurement is displayed inside the bounded region.

8. The electronic device of claim 6 , wherein the second user input comprises a touch input and the third user input comprises a touch input.

9. The electronic device of claim 8 , wherein the second user input comprises multi touch gestures on the guide UI item and touch movement gestures to other positions.

10. The electronic device of claim 6 , wherein the first line is displayed on at least part of the at least one line of the guide UI item.
