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 according to the present invention 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: receiving a first touch input on the screen of the electronic device during a first time period; displaying guide information comprising at least one line, wherein the at least one line defines a bounded region on the screen, in response to receiving the first touch input; receiving a second touch input on the screen of the electronic device during a second time period, the second time period overlapping the first time period; displaying a first line responsive to receiving the second touch input based on the guide information, a length of the first line being changeable responsive to receiving the second touch input, wherein the first line is adjacent to the guide information; and displaying supplemental information related to the first line in the bounded region on the screen responsive to receiving the second input, the supplemental information including a numeric measurement related to the first line, the supplemental information being changeable responsive to receiving the second touch input.

2. The method of claim 1 , wherein the numeric measurement includes a value corresponding to the length of the first line.

3. The method of claim 1 , wherein the guide information includes information on length based on the at least one line.

4. The method of claim 1 , wherein the guide information comprises information indicative of the first line.

5. The method of claim 1 , wherein the first line is formed from the at least one line.

6. The method of claim 1 , wherein the second touch input comprises a gesture, and wherein displaying the first line further comprises displaying the first line according to the gesture.

7. The method of claim 1 , further comprising receiving a selection input related to the second input; and displaying the first line being fixed in response to the selection input.

8. The method of claim 7 , further comprising: removing at least one of the guide information and the supplemental information from the screen of the electronic device in response to the selection input.

9. The method of claim 1 , wherein the first touch input is movable, and wherein the guide information is moveable according to movements of the first touch input.

10. The method of claim 1 , wherein at least a portion of the guide information is replaced by the first line.

11. The method of claim 1 , wherein the first line contacts the guide information.

12. The method of claim 1 , wherein as the touch input is dragged from a first point to a second point, the guide information is stationary.

13. A non-transitory computer-readable medium storing a plurality of instructions, wherein execution of the plurality of instructions by one or more processors causes performance of the method of claim 1 .

14. An electronic device, the electronic device comprising;
an input unit configured to receive at least one touch input;
a display configured to display at least one information; and
a control unit configured to control:
receiving, by the input unit, a first touch input on a screen of the electronic device during a first time period;
displaying, by the display, guide information comprising at least one line, wherein the at least one line defines a bounded region on the screen, in response to receiving the first touch input
receiving, by the input unit, a second touch input during a second time period, the second time period overlapping the first time period;
displaying, by the display, a first line responsive to receiving the second touch input based on the guide information, a length of the first line being changeable responsive to receiving the second touch input, wherein the first line is adjacent to the guide information; and
displaying, by the display, supplemental information related to the first line in the bounded region on the screen responsive to receiving the second input, the supplemental information including a numeric measurement related to the first line, the supplemental information being changeable responsive to receiving the second touch input.

15. The electronic device of claim 14 , wherein the numeric measurement includes a value corresponding to the length of the first line.

16. The electronic device of claim 14 , wherein the guide information includes information on length for the at least one line.

17. The electronic device of claim 14 , wherein the guide information comprises information indicative of the first line.

18. The electronic device of claim 14 , wherein the first line is formed from the at least one line.

19. The electronic device of claim 14 , wherein the second touch input comprises a gesture, and wherein displaying the first line further comprises displaying the first line according to the gesture.

20. The electronic device of claim 14 , wherein the control unit is further configured to control: receiving, by the input unit, a selection input related to the second input; and displaying, by the display, the first line being fixed in response to the selection input.

21. The electronic device of claim 20 , wherein the control unit is further configured to control: removing, by the display, at least one of the guide information and the supplemental information from the screen of the electronic device in response to the selection input.

22. The electronic device of claim 14 , wherein the first touch input is movable, and wherein the guide information is moveable according to movements of the first touch input.
