Abstract

A user terminal device is provided, which includes a sensor configured to sense a user operation with respect to a display; and a controller configured to operate in a first interaction mode in which an operation that corresponds to a touch point of a pen is performed if a pen touch with respect to the display is sensed by the sensor, to switch over to a second interaction mode if the controller determines that the pen is put on the display, and to perform an operation that corresponds to a line on the display on which the pen is put.

Claims

1. A user terminal device comprising:

a sensor configured to sense a user operation with respect to a display; and

a controller configured to operate in a first interaction mode in which an operation that corresponds to a touch point of a pen is performed if a pen touch with respect to the display is sensed by the sensor, to switch over to a second interaction mode if the controller determines that the pen is put on the display, and to perform an operation that corresponds to a line on the display on which the pen is put.

2. The user terminal device as claimed in claim 1, wherein if the sensor simultaneously senses a hovering operation of the pen at a plurality of points on the display, and the controller determines that a distance between the plurality of points corresponds to a length of the pen, the controller thereby determines that the pen is put on the display.

3. The user terminal device as claimed in claim 1, wherein if the sensor senses that an object that is included in a screen displayed on the display is touched by the pen in the first interaction mode, the controller executes a program that matches the object.

4. The user terminal device as claimed in claim 1, wherein if the sensor senses that a drawing is created by the pen on a screen displayed on the display in the first interaction mode, the controller displays a line according to a trace of the drawing.

5. The user terminal device as claimed in claim 1, wherein if the controller determines that the pen is put on an object that is included in a screen displayed on the display, the controller switches over to the second interaction mode, fixes the object based on the line on the display on which the pen is put, and changes a shape of the object according to a subsequent user operation.

6. The user terminal device as claimed in claim 1, wherein if the sensor senses a subsequent user operation to move an object that is included in a screen displayed on the display in a direction towards the line on the display on which the pen is put in the second interaction mode, the controller aligns the object based on the line.

7. A user terminal device comprising:

a sensor configured to sense a pen operation by a pen having a nib comprising a core connected to a built-in coil and a conductor connected to a conductive body; and

a controller configured to perform a first interaction operation if the conductor touches a display and to perform a second interaction operation that is different from the first interaction operation if the core touches the display.

8. The user terminal device as claimed in claim 7, wherein the first interaction operation is an operation to select an object displayed at a touch point, and the second interaction operation is an operation to draw a line along a handwriting trace of the pen.

9. An interaction method of a user terminal device, the interaction method comprising:

operating, in response to sensing a pen touch with respect to a display of the user terminal device, in a first interaction mode to perform an operation that corresponds to a touch point of a pen;

switching over to a second interaction mode in response to determining that the pen is put on the display; and

performing, in response to a subsequent user operation being performed in a state where the user terminal device operates in the second interaction mode, an interaction operation that corresponds to a line on which the pen is put and the subsequent user operation.

10. The interaction method as claimed in claim 9, wherein the switching over to the second interaction mode comprises determining that the pen is put on the display in response to simultaneously sensing a hovering operation of the pen at a plurality of points on the display and determining that a distance between the plurality of points corresponds to a length of the pen.

11. The interaction method as claimed in claim 9, further comprising executing, in response to determining that an object that is displayed on the display is touched by the pen in the first interaction mode, a program that matches the object.

12. The interaction method as claimed in claim 9, further comprising displaying, in response to sensing a drawing by the pen on the display in the first interaction mode, a line according to a trace of the drawing.

13. The interaction method as claimed in claim 9, wherein the performing the interaction operation comprises fixing, if the pen is put on an object that is displayed on the display, the object based on the line on which the pen is put, and changing a shape of the object according to the subsequent user operation.

14. The interaction method as claimed in claim 9, wherein the performing the interaction operation comprises aligning, in response to sensing the subsequent user operation to move an object that is displayed on the display in a direction towards the line on which the pen is put in the second interaction mode, the object based on the line.

15. An interaction method of a user terminal device, the interaction method comprising:

sensing whether a pen having a nib comprising a core connected to a built-in coil and a conductor connected to a conductive body touches a display of the user terminal device; and

performing a first interaction operation if the sensing indicates that the conductor touches the display and performing a second interaction operation that is different from the first interaction operation if the sensing indicates that the core touches the display.

16. The interaction method as claimed in claim 15, wherein the first interaction operation is an operation to select an object displayed at a touch point, and the second interaction operation is an operation to draw a line along a handwriting trace of the pen.

17. A user terminal device comprising:

a sensor configured to sense a touch of a pen comprising a nib that is formed in an inclined line edge shape; and

a controller configured to operate in one of a plurality of different interaction modes according to a touch area if the pen touches a display and to perform an interaction operation that corresponds to the touch area of the pen.

18. A mobile device comprising:

a sensor configured to sense a first touch event indicating that a touching device is touching a display of the mobile device in a first touch area, and to sense a second touch event indicating that the touching device is touching the display in a second touch area, the first touch area being smaller than the second touch area; and

a controller configured to perform a first interaction operation in response to the sensor sensing the first touch event, and to perform a second interaction operation which is different from the first interaction operation in response to the sensor sensing the second touch event.

19. The mobile device as claimed in claim 18, wherein the first interaction operation comprises drawing a line on a screen of the display according to a movement of the pen, and the second interaction operation comprises scrolling the screen according to the movement of the pen.

20. The mobile device as claimed in claim 18, wherein the first interaction operation comprises drawing a line on a screen of the display according to a movement of the pen, and the second interaction operation comprises erasing the line according to the movement of the pen.
