3 is a diagram illustrating a process of copying and moving a first object displayed on a first screen according to a user's input.

3A, a first user U1 positioned in a first direction D1 of the transparent display panel 100 views a first object 11 displayed on a first screen 101, Lt; / RTI > user U2.

The first user U1 attempts to communicate with the second user U2 by showing the same object as the first object 11. [ When the first user U1 inputs the first input 11, the control unit 330 generates a control signal for copying the entire first object 11, .

For example, the first input 11 may be a double tap operation on the first object 11. In this case, when the double tap is detected on the first object 11, the entire first object 11 is copied. Hereinafter, the copied object is referred to as a second object 21.

3B, when the first user U1 inputs the second input I22, the controller 330 generates a control signal for moving the second object 21 and transmits the control signal to the movement unit 390 ).

For example, the second input I22 may be an operation of dragging the copied second object 21. In this case, the second object 21 moves in the drag direction and can be fixed at a point where the drag stops.

At this time, the first user U1 can see both the first object 11 and the second object 21 displayed on the first screen 101, and the first object 11 and the second object The second object 21 displays the same information. The first object 11 and the second object 21 may be spaced apart from each other by a predetermined distance and may be located on the same line.

4 is a diagram illustrating a process of rotating a second object displayed on a first screen according to an input of a user and displaying the rotated second object on a second screen.

4A and 4B, when the first user U1 inputs the third inputs I31 and I32, the controller 330 generates a control signal for rotating the second object 21 To the rotation unit 370.

For example, the third inputs I31 and I32 are pressed on the second object 21 with a plurality of fingers (I31), and the second object 21 is dragged successively. Lt; RTI ID = 0.0 > (I32). ≪ / RTI > In this case, the second object 21 may be rotated 180 degrees in the drag direction from the current position and displayed on the second screen 102 opposite to the current position.

Referring to FIG. 4C, the back side 22 of the second object 21 is displayed on the first screen 101 and the second user U2 on the opposite side is displayed on the second screen 102 The second object 21 can be seen. Thus, the first user U1 and the second user U2 can share information of the same contents while facing each other.

5 is a diagram illustrating a process of displaying information according to a user's input and performing a partial copy of a second object.

Referring to FIG. 5A, the second user U2 can see the second object 21 and the back side 12 of the first object 11. In FIG. When the second user U2 inputs information to the second object 21, the information is displayed on the second object 21. For example, the input information may be text. The information may be an input method editor (IME), which is a virtual soft keyboard displayed on the transparent display panel 100, or a keyboard separately formed from the transparent display panel 100.

5B and 5C, when the second user U2 inputs the fourth inputs I41 and I42, the controller 330 performs a partial copy of the second object 21.

For example, the fourth inputs I41 and I42 may be generated by dragging the first object 11 (actually, the back surface 12 of the first object) and the second object 21 (I41) , And bumping (I42). In this case, it can be emphasized that one side of the first object 11 and one side of the second object 21 are in contact with each other. For example, the opposite side edge 31 may be marked with a red shadow so that the user can easily recognize that some copying can proceed.

6 is a view illustrating a process of displaying information according to a user's input and transmitting only a part of a second object to a first object.

6A and 6B, when the second user U2 inputs the fifth input I51 or I52 to the corresponding region of the second object 21 to copy only the portion of the information input by the second user U2, The control unit 330 copies only the corresponding area of the second object 21 and transmits the same to the first object 11.

For example, the fifth input (I51, I52) is dragged (I52) after pressing (I51) with a plurality of fingers on the second object (21) corresponding to the partially copied area ) May be a series of operations.

The second object 21 can be divided into a plurality of areas in which a part of copying is performed, and new information is input and only a part that needs to be replaced is replaced. The second object 21 may be divided into a first area 210, a second area 220 and a third area 230. The second object 21 may be divided into a first area 210, Only partially copied and rotated. Accordingly, the first object 11 is displayed by replacing the area corresponding to the copied partial area of the second object 21.

In the present embodiment, the second user U2 inputs text information into the second area 220 and inputs the fifth input I51 and I52 into the second area 220.

Referring to FIG. 6C, the first object 11 is replaced with a region corresponding to the second region 220 of the second object 21, and the first user U1 transmits the second user U2) can see the text entered.

At this time, the users U1 and U2 are recognized that the inputted text information is transmitted from the second object 21 to the first object 11. [ However, in reality, the first object 11 is changed by copying and rotating a part of the second object 21, and the transferred file may be a picture file such as jpeg, not a text file. In this case, it is possible to display the image in real time because the load of the control unit 330 is reduced rather than the text file is transmitted.

In this embodiment, the fifth inputs I51 and I52 for the partial copy may be the same as the third inputs I31 and I32 for the full copy in FIG. At this time, as described with reference to FIG. 5, by performing a partial copy through the fourth inputs I41 and I42, it is possible to distinguish between a full copy mode and a partial copy mode.

For example, if the third input I31 and I32 are received while the first object 11 and the second object 21 are spaced apart, the entire object can be rotated. On the other hand, if the fifth input (I51, I52) is received while the first object 11 and the second object 21 are in contact with each other, only a part of the object can be rotated.

Although FIG. 6 illustrates a partial copy of the second object 21, it is needless to say that some copying of the first object 11 is also possible. A partial copy of the first object 11 will be described with reference to FIG.

7 is a diagram illustrating a process of inputting information at a first user side and copying only a part of a first object to a second object.

Referring to FIG. 7A, the first user U1 receives the information input by the second user U2 and can modify the information again. As a remedy, information input by the second user U2 is displayed on the first object 11 in which the portion transmitted in FIG. 6C is replaced.

The first user U1 can change the information inputted by the second user U2 such as delete, modify, add, and the like. Similarly, the first object 11 may be divided into a first region 110, a second region 120, and a third region 130, and the second user U2 may divide only the modified region into the first region 110, 2 object (21). In this embodiment, a partial copy of the second area 120 of the first object 11 corresponding to the second area 220 of the second object 21 proceeds.

7B and 7C, when the first user U1 inputs the fifth inputs I51 and I52 to the second region 120, the controller 330 controls the second region 120, Only the second area 220 of the second object 21 corresponding to the second area 120 is copied and transferred.

7D, the second object 21 is replaced with a second region 220 corresponding to the second region 120 of the first object 11, and the second user U2 The text input by the first user U1 can be viewed.

According to the transparent display device and the method for providing a user interface thereof according to the present embodiment, an intuitive user interface environment is provided to a user on a two-sided side of a transparent display device using a transparent display property. Therefore, the user can realize the sensory interchange through the interaction between the two, so that the transparent display device can be utilized effectively.
