Abstract

An electronic device for displaying a three-dimensional image and a method of using the same, and more particularly, to an electronic device for displaying a three-dimensional image and a method of using the same that can provide a user interface for controlling positions of a three-dimensional icon and a virtual layer including the same according to a user gesture are provided. The electronic device for displaying a three-dimensional image includes a camera for photographing a gesture action in three-dimensional space; a display unit for displaying a virtual layer including at least one object with a first depth at three-dimensional virtual space; and a controller for selectively performing one of a first action of changing a depth in which the virtual layer is displayed to a second depth and a second action of changing a position of the object, according to the gesture action based on a gesture input mode.

Claims

1. An electronic device, comprising:

a camera configured to capture a gesture of a user located in a field of view of the camera;

a three-dimensional (3D) display unit configured to generate a plurality of virtual planes comprising one of a first virtual plane and a second virtual plane different from the first virtual plane, and display a plurality of objects on the plurality of virtual planes as a 3D image;

a controller configured to change one of a display characteristic of the objects and a virtual plane characteristic based on the captured gesture and a gesture mode of the electronic device,

wherein the display characteristic is one of a vertical location and a horizontal location of the objects within the one of the first and second virtual planes,

wherein the virtual plane characteristic is a depth of the one of the first and second virtual planes, and

wherein the gesture mode comprises;

a first mode changing a position of the plurality of virtual planes in a 3D space, and

a second mode changing a position of at least one of the plurality of objects from the first virtual plane to the second virtual plane in the 3D space,

wherein the controller is further configured to execute a function based on the gesture mode when an attribute of the captured gesture is greater than a critical value, the attribute comprising at least one of a moving speed and a moving distance of the captured gesture.

2. The electronic device of claim 1, wherein the captured gesture is a gesture substantially toward or away from the camera.

3. The electronic device of claim 1, wherein the captured gesture comprises simultaneous first and second gestures separated by a specific distance.

4. The electronic device of claim 1,

wherein the display characteristic is an assignment of the objects to the one of the first and second virtual planes, and

wherein the controller is configured to change the assignment of the objects from the first virtual plane to the second virtual plane, or from the second virtual plane to the first virtual plane.

5. The electronic device of claim 4, wherein the first and second virtual planes are located on a common plane separated by a predetermined distance.

6. The electronic device of claim 1, wherein the controller is configured to:

horizontally rotate the one of the first and second virtual planes around a virtual point in front of the 3D display unit, or

vertically rotate the one of the first and second virtual planes around the virtual point in front of the 3D display unit.

7. The electronic device of claim 1, wherein the controller is configured to set the gesture mode based on a specific user gesture captured by the camera.

8. The electronic device of claim 1, wherein the controller is configured to set the gesture mode based on one of a user voice command and a user input to a control device connected to the electronic device via one of a wired connection and a wireless connection.

9. The electronic device of claim 1, wherein the controller is configured to change the one of the display characteristic of the objects and a virtual plane characteristic based on one of a speed and a distance of the captured gesture.

10. The electronic device of claim 1, wherein the first virtual plane and the second virtual plane are substantially parallel to each other and to a display surface of the 3D display unit.

11. A method of controlling a three-dimensional (3D) display device having a camera, the method comprising:

capturing a gesture of a user located in a field of view of the camera;

generating a plurality of virtual planes comprising one of a first virtual plane and a second virtual plane different from the first virtual plane;

displaying a plurality of objects on the plurality of virtual planes as a 3D image; and

changing one of a display characteristic of the objects and a virtual plane characteristic based on the captured gesture and a gesture mode of the electronic device,

wherein the display characteristic is one of a vertical location and a horizontal location of the objects within the one of the first and second virtual planes,

wherein the virtual plane characteristic is a depth of the one of the first and second virtual planes, and

wherein the gesture mode comprises;

a first mode changing a position of the plurality of virtual planes in a 3D space, and

a second mode changing a position of at least one of the plurality of objects from the first virtual plane to the second virtual plane in the 3D space,

wherein the controller is configured to execute a function based on the gesture mode when an attribute of the captured gesture is greater than a critical value, the attribute comprising at least one of a moving speed and a moving distance of the captured gesture.

12. The method of claim 11, wherein the captured gesture is one of:

a gesture substantially toward or away from the camera,

a gesture substantially across the field of view of the camera, and

simultaneous first and second gestures separated by a specific distance.

13. The method of claim 11,

wherein the display characteristic is an assignment of the objects to the one of the first and second virtual planes, and

wherein the step of changing the display characteristic includes changing the assignment of the objects from the first virtual plane to the second virtual plane, or from the second virtual plane to the first virtual plane.

14. The method of claim 13, wherein the first and second virtual planes are located on a common plane separated by a predetermined distance.

15. The method of claim 11, wherein the step of changing the virtual plane characteristic comprises one of:

vertically rotating the one of the first and second virtual planes around a virtual point in front of the 3D display unit; and

horizontally rotating the one of the first and second virtual planes around the virtual point in front of the 3D display unit.

16. The method of claim 11, further comprising:

setting the gesture mode based on one of;

a specific user gesture captured by the camera,

a user voice command, and

a user input to a control device connected to the 3D display device via one of a wired connection and a wireless connection.

17. The method of claim 11, wherein the step of changing comprises:

changing the one of the display characteristic of the objects and the virtual plane characteristic based on one of a speed and a distance of the captured gesture.

18. The method of claim 11, wherein the first virtual plane and the second virtual plane are substantially parallel to each other and to a display surface of the 3D display device.
