Abstract

The present disclosure relates to a mobile terminal and a 3D object control method thereof for controlling the depth or rotation of a 3D object using a 3D manipulation portion displayed around the 3D object. According to the present invention, a circular- or ring-shaped 3D manipulation portion may be touched to intuitively control the rotation and enlargement/reduction of the 3D object, thereby providing usefulness and convenience for the user, capable of editing the 3D object while directly viewing the transformed form and depth of the 3D object.

Claims

1. A display method of a mobile terminal, the method comprising:

displaying at least one perceived 3-dimensional (3D) object on a display;

selecting a specific 3D object from the display;

displaying, on the display, a 3D manipulation portion having a predetermined shape in an area about the selected 3D object;

detecting a touch input within the 3D manipulation portion; and

adjusting a rotation and a depth of the 3D object based on a touch location and a touch type of the touch input within the displayed 3D manipulation portion.

2. The method of claim 1, wherein the selected 3D object is one of an image, a picture, a widget, a text, an icon, or a graph.

3. The method of claim 1, wherein the 3D manipulation portion is displayed to correspond to the displayed 3D object, and the 3D manipulation portion has a shape of a circle, a band, or a ring.

4. The method of claim 1, wherein displaying the 3D manipulation portion includes displaying the 3D manipulation portion when the 3D object is selected by one of a long touch, a double touch, or a 3D hot key &

touch.

5. The method of claim 1, wherein displaying the 3D manipulation portion includes displaying the 3D manipulation portion about a current 3D object, about an enlarged 3D object, or about a 3D object in a mini map.

6. The method of claim 1, further comprising increasing a size of the displayed 3D manipulation portion in response to each multi-tap input.

7. The method of claim 1, wherein on/off, color, size, thickness, form, depth or rotation angle of the 3D manipulation portion are set based on input to a user menu displayed on the display.

8. The method of claim 1, wherein a form and a depth of the 3D object changes based on the touch location and the touch type of the touch input within the 3D manipulation portion, and a shape, a color, or a depth of the 3D manipulation portion changes to correspond to the changed form and depth of the 3D object.

9. The method of claim 1, wherein the touch location of the touch input within the 3D manipulation portion includes a touch to the 3D manipulation portion or a touch to an outer region of the 3D manipulation portion, and the touch type of the touch input within the 3D manipulation portion includes a single-touch &

drag or a multi-touch &

drag.

10. The method of claim 1, wherein adjusting the rotation and the depth of the 3D object comprises:

enlarging or reducing a size of the 3D object based on the touch type of the touch input and adjusting the depth of the 3D object based on a ratio of enlargement/reduction when the touch location of the touch input within the 3D manipulation portion is an outer region of the 3D manipulation portion; and

rotating or enlarging/reducing the 3D object based on the touch type of the touch input and adjusting the depth of the 3D object based on a ratio of enlargement/reduction when the touch location of the touch input within the 3D manipulation portion is the 3D manipulation portion.

11. The method of claim 1, further comprising:

determining whether one or more setting values are stored in memory when the 3D object is selected;

applying the setting value to the 3D object when there exists only one stored setting value in the memory;

displaying, on the display, a plurality of candidate setting values when there exists more than one stored setting values in the memory; and

individually or collectively applying the setting values selected from the plurality of candidate setting values to the 3D object.

12. A mobile terminal comprising:

a display to display a perceived 3-dimensional (3D) object; and

a controller to control the display to display a perceived 3D manipulation portion having a predetermined shape in an area about the 3D object when a specific 3D object is selected from the display, and the controller to adjust a rotation and a depth of the 3D object based on a touch location and a touch type of a touch input within the 3D manipulation portion.

13. The mobile terminal of claim 12, wherein the selected 3D object is one of an image, a picture, a widget, a text, an icon, or a graph.

14. The mobile terminal of claim 12, wherein the controller controls the display to display the 3D manipulation portion to correspond to the displayed 3D object, and the 3D manipulation portion has a shape of a circle, a band, or a ring.

15. The mobile terminal of claim 12, wherein the controller displays the 3D manipulation portion on the display when the 3D object is selected by one of a long touch, a double touch, or a 3D hot key &

touch.

16. The mobile terminal of claim 12, wherein the controller increases a size of the displayed 3D manipulation portion in response to each multi-tap input.

17. The mobile terminal of claim 12, wherein the controller controls a form and a depth of the 3D object to change based on the touch location and the touch type of the touch input within the 3D manipulation portion, and a shape, a color, or a depth of the 3D manipulation portion changes to correspond to the changed form and the depth of the 3D object.

18. The mobile terminal of claim 12, wherein the touch location of touch input within the 3D manipulation portion includes a touch to the 3D manipulation portion or a touch to an outer region of the 3D manipulation portion, and the touch type of the touch input to the 3D manipulation portion includes a single-touch &

drag or a multi-touch &

drag.

19. The mobile terminal of claim 12, wherein the controller rotates the displayed 3D object when part of the 3D manipulation portion is single-touched and is then dragged in a predetermined direction based on a point of the 3D object, and the controller adjusts the depth of the 3D object while enlarging or reducing the 3D object when an outer region of the 3D manipulation portion is touched and dragged to an inner side or an outer side of the 3D manipulation portion.

20. The mobile terminal of claim 12, wherein the controller adjusts the depth of the displayed 3D object while enlarging or reducing the displayed 3D object when the 3D manipulation portion is multi-touched or an outer region of the 3D manipulation portion is multi-touched and is then widened or narrowed.

21. The mobile terminal of claim 12, wherein the controller determines whether a setting value exists in memory when the 3D object is selected and automatically applies the setting value to the 3D object when there exists only one stored setting value in the memory, and the controller displays a plurality of candidate setting values when more than one setting values are stored in the memory.

22. A method comprising:

displaying a perceived 3-dimensional (3D) object on a display of a mobile terminal;

receiving an object input to select at least one perceived 3D object displayed on the display;

displaying, on the display, an editing indicator in an area about the selected 3D object, wherein the editing indicator is displayed while the 3D object is displayed on the display;

detecting a touch input with respect to the displayed editing indicator; and

changing an orientation and a depth of the displayed 3D object based on a location and a type of the detected touch input with respect to the displayed editing indicator.

23. The method of claim 22, wherein the orientation includes one of a rotation, an enlargement, a reduction, a shape or a color of the displayed 3D object.

24. The method of claim 22, wherein the editing indicator surrounds the displayed editing indicator.

25. The method of claim 22, wherein the mobile terminal enters an editing mode of the 3D object in response to receiving the object input.
