Abstract

A screen operation method for an electronic device based on the electronic device and a control action is disclosed. The electronic device may include an input data receiving module for receiving input data through the device from a user, a unit presentation recognizing module for recognizing a unit presentation from the input data in order to control the electronic device, and a screen controlling module for controlling the screen of the electronic device based on the control action with which the unit presentation is combined.

Claims

1. An electronic device comprising:

an input data receiver configured to receive input data from a user through an electronic device;

a unit expression recognizer configured to recognize a unit expression for controlling the electronic device from the input data; and

a screen controller configured to control a screen of the electronic device in response to a control operation that is a combination of at least two unit expressions.

2. The electronic device of claim 1, wherein the at least two unit expressions are selected from a closed curve, a line, and a point.

3. The electronic device of claim 1, wherein the screen controller is further configured to enlarge a particular area related to a closed curve in response to the control operation comprising the user drawing the closed curve on the screen and then drawing a line from a boundary of the closed curve away from the closed curve on the screen.

4. The electronic device of claim 3, wherein the screen controller is further configured to determine a zoom scaling factor of the particular area based on a distance from a center of the closed curve to the closed curve and a length of the line.

5. The electronic device of claim 1, wherein the screen controller is further configured to reduce a particular area related to a closed curve in response to the control operation comprising the user drawing the closed curve on the screen and then drawing a line from a boundary of the closed curve into the closed curve on the screen.

6. The electronic device of claim 5, wherein the screen controller is further configured to determine a reduction ratio of the particular area based on a distance from a center of the closed curve to the closed curve and a length of the line.

7. The electronic device of claim 1, wherein the screen controller is further configured to move a particular area to a center of the screen and enlarge the particular area to a full screen in response to the control operation comprising the user drawing a closed curve surrounding the particular area on the screen and then drawing a point outside the closed curve on the screen.

8. The electronic device of claim 1, wherein the screen controller is further configured to move a particular area to a center of the screen in response to the control operation comprising the user drawing a closed curve surrounding the particular area on the screen and then drawing a point inside the closed curve on the screen.

9. The electronic device of claim 1, wherein the screen controller is further configured to move a first particular area to a center of a closed curve surrounding a second particular area in response to the control operation comprising the user drawing a closed curve surrounding the first particular area on the screen and then drawing the closed curve surrounding the second particular area on the screen.

10. The electronic device of claim 1, wherein the screen controller is further configure to move an entire screen along a drag track in response to the control operation comprising the user drawing a point and then dragging the point to a predetermined position along drag track on the screen.

11. The electronic device of claim 1, wherein the screen controller is further configured to rotate the screen in a direction of drawing a line in response to the control operation comprising the user drawing a closed curve on the screen and then drawing the line in a particular direction from a boundary of the closed curve along the closed curve.

12. The electronic device of claim 11, wherein the screen controller is further configured to determine an angle by which the screen is to be rotated to be an angle between a first vector from a center of the closed curve to a starting point of the line and a second vector from the center of the closed curve to an ending point of the line.

13. The electronic device of claim 1, wherein the screen controller is further configured to cancel a previous operation performed through the screen in response to the control operation comprising the user drawing a closed curve on the screen and then a straight line passing through an inside of the closed curve on the screen.

14. The electronic device of claim 1, wherein the screen controller is further configured to repeat a previous operation performed through the screen in response to the control operation comprising the user drawing a closed curve on the screen and then a curved line extending into and then out of the closed curve on the screen.

15. The electronic device of claim 1, wherein the unit expression recognizer is further configured to recognize the unit expression based on an input pattern related to continuity of the input data.

16. The electronic device of claim 1, wherein the unit expression recognizer is further configured to recognize the unit expression from the input data of the user received after the electronic device is converted to a screen control mode by the user.

17. The electronic device of claim 1, wherein the unit expression recognizer is further configured to recognize the unit expression using an error correction rule related to the unit expression.

18. An electronic device configured to recognize a control operation that is a combination of at least two unit expressions selected from a closed curve, a line, and a point, and control a screen in response to the control operation;

wherein the control operation is selected from zoom in, zoom out, zoom to fit on the screen, move to a center of the screen, move to an arbitrary point on the screen by jumping, move to an arbitrary point on the screen by dragging, rotate, undo, and redo.

19. A screen manipulation method for an electronic device, the screen manipulation method comprising:

receiving input data from a user through the electronic device;

recognizing a unit expression for controlling the electronic device from the input data; and

controlling a screen of the electronic device in response a control operation that is a combination of at least two unit expressions.

20. The screen manipulation method of claim 19, wherein the control operation is selected from zoom in, zoom out, zoom to fit on the screen, move to a center of the screen, move to an arbitrary point on the screen by jumping, move to an arbitrary point on the screen by dragging, rotate, undo, and redo.
