The structure of the external electronic devices 200-1 and 200-2 shown in FIG. 1 is similar to that of the electronic device 100 described with reference to FIG. 2, 1 and 200-2 will not be described.

Embodiments disclosed in this document can be implemented in the electronic device 100 described with reference to Figs. 1 and 2. Fig.

Hereinafter, a content sharing method of an electronic device according to a first embodiment of the present invention and an operation of an electronic device for implementing the content sharing method will be described in detail with reference to FIG. 3 to FIG.

3 is a flowchart illustrating a content sharing method of an electronic device according to a first embodiment of the present invention. 4 to 9 are views for explaining a content sharing method according to the first embodiment of the present invention.

3, the controller 180 connects to the first external electronic device 200-1 through the communication unit 110 (S101).

When the contents to be shared are displayed in the first external electronic device 200-1 in step S102, the controller 180 continuously calculates the distance between the electronic device 100 and the first external electronic device 200-1 (S103). Here, the contents may be displayed on the screen of the electronic device 100 while the shared contents are displayed through the first external electronic device 200-1.

On the other hand, if the distance between the electronic device 100 and the first external electronic device 200-1 is changed during the display of the shared content (S104), the control unit 180 displays the first external electronic device 200-1 (S105). ≪ / RTI >

On the other hand, in step S103, the controller 180 can acquire distance information between the electronic device 100 and the first external electronic device 200-1 in various ways. 4 to 6 illustrate examples of obtaining distance information between the electronic device and each external electronic device.

4, the controller 180 acquires position information from the first external electronic device 200-1 (S201). Then, based on the obtained location information and the current location of the electronic device 100, a distance or distance change between the two electronic devices 100 and 200-1 is obtained (S202).

5, for example, the control unit 180 may compare the received signal strength acquired by the first external electronic device 200-1 with the signal transmitted through the communication unit 110 to the first external electronic device 200-1 (S301). Based on this, a distance or distance change between the two electronic devices 100 and 200-1 is obtained (S302).

6, the control unit 180 controls the first external electronic device 200-1 to receive the signal transmitted through the communication unit 110 from the first external electronic device 200-1 (S401). Based on this, the distance or distance change between the two electronic devices 100 and 200-1 is obtained (S402).

Referring again to FIG. 3, in step S104, the controller 180 varies the display size or the display position of the content displayed on the first external electronic device 200-1, so that the first external electronic device 200- 1 can be varied. 7 and 8 show examples of varying display characteristics of contents.

7, the controller 180 displays the first external electronic device 200-1 on the first external electronic device 200-1 as the distance between the electronic device 100 and the first external electronic device 200-1 moves away from d1 to d2 It is possible to control the size of the content to gradually decrease (S501, S502). The fact that the electronic device 100 is away from the first external electronic device 200-1 when the electronic device 100 is a mobile terminal being used by the user means that the user is away from the first external electronic device 200-1 it means. That is, it may mean that the user's interest in the content being displayed on the first external electronic device 200-1 is reduced. Accordingly, the controller 180 can control the first external electronic device 200-1 so that the size of the contents is gradually reduced according to the decrease in the degree of interest of the user.

8, the controller 180 displays the first external electronic device 200-1 on the first external electronic device 200-1 as the distance between the electronic device 100 and the first external electronic device 200-1 moves away from d1 to d2 It may be controlled so that the size of the content gradually increases (S601, S602). The fact that the electronic device 100 is away from the first external electronic device 200-1 when the electronic device 100 is a mobile terminal being used by the user means that the user is away from the first external electronic device 200-1 it means. Therefore, in this case, the size of the contents can be gradually reduced according to the decrease of the interest of the user.

7 and 8, as the distance between the electronic device 100 and the first external electronic device 200-1 is shifted away from d1 to d2, the controller 180 controls the first external electronic device 200-1, The position at which the content is displayed on the device 200-1 may also be variable.

3, in step S105, the controller 180 directly controls the display characteristics of the content to control the display characteristics of the content displayed on the first external display 200-1, To the first external electronic device 200-1.

For example, the control unit 180 directly controls the display characteristics of the content transmitted to the first external electronic device 200-1, thereby controlling the display characteristics of the content displayed on the second external electronic device 200-1 . That is, the display characteristics of the content can be varied and transmitted to the first external electronic device 200-1, thereby controlling the display characteristics of the content displayed on the first external electronic device 200-1. In this case, the content displayed on the first external electronic device 200-1 is transferred to the first external electronic device 200-1 after the display characteristic is changed by the control unit 180. [

In addition, for example, the control unit 180 transmits a control signal for controlling the content display characteristic to the first external electronic device 200-1 to display the display characteristic of the content displayed on the first external electronic device 200-1 . In this case, the content displayed on the first external electronic device 200-1 may be a content transferred from the electronic device 100 or another external electronic device to the first external electronic device 200-1, And may be pre-stored in the electronic device 200-1.

3, when the distance between the electronic device 100 and the first external electronic device 200-1 is changed, the controller 180 controls the first external electronic device 200-1 to the electronic device 100, The second external electronic device 200-2 is searched for closer (S106).

Here, the electronic device 100 searches for the second external electronic device 200-2 closer to the electronic device 100 using the methods described with reference to Figs. 4 to 6 described above.

For example, the control unit 180 compares received signal strengths received from the two external electronic devices 200-1 and 200-2 to determine whether the electronic devices 100-1 and 200-2 of the two external electronic devices 200-1 and 200-2 Can be obtained. Further, for example, the control unit 1800 compares the reception times received from the two external electronic devices 200-1 and 200-2, and determines whether the external electronic device having a high reception time is outside the electronic device 100 It recognizes that it is an electronic device.

On the other hand, if the second external electronic device 200-2 closer to the electronic device 100 is found than the first external electronic device 200-1, the control unit 180 controls the first external electronic device 200-1, And controls the two external electronic devices 200-1 and 200-2 so that the content being displayed in the second external electronic device 200-2 is displayed (S107). That is, the content being displayed through the first external electronic device 200-1 is transferred to the second external electronic device 200-2, or the content is transferred from the first external electronic device 200-1 to the second external electronic device 200-1, And controls the first external electronic device 200-1 to be transmitted to the first external electronic device 200-2.

2, when the second external electronic device 200-2 closer to the first external electronic device 200-1 is searched, the second external electronic device 200-2 automatically detects the contents Display is controlled by way of example, the present invention is not limited thereto. In the present invention, when the second external electronic device 200-2 closer to the first external electronic device 200-1 is searched, the second external electronic device 200-2 is connected to the second external electronic device 200-2 through the user input unit 130 The content is displayed through the second external electronic device 200-2 only when it is requested to display the content. 9 shows a second external electronic device 200-2 which is closer to the electronic device 100 than the first external electronic device 200-1 while displaying the content through the first external electronic device 200-1. It is displayed through the display module 151 and is notified to the user. 9, the control unit 180 displays a selection window 41 for selecting whether to display the content on the second external electronic device 200-2, that is, the "computer 1", through the display module 151 do. Accordingly, the user selects whether to allow the second external electronic device 200-2 to display the content through the user input unit 130. [

Hereinafter, a content sharing method of an electronic device according to a second embodiment of the present invention and an operation of the electronic device 100 for implementing the same will be described in detail with reference to FIGS. 10 to 11. FIG.
