FIG. 1 and FIG. 2 illustrate an example of a content moving environment between devices in an embodiment of the present invention.

The content moving system according to an embodiment may include a first device 110 and a second device 120. [

The first device 110 may be a smart phone, a tablet, a wearable computer, a laptop computer, or the like, including a display capable of touch input. In this case, the first device 110 is a device having a light source output means capable of controlling a light source at a predetermined position of the main body, and a camera flash, a display light source, or the like can be used as the light source output means.

The second device 120 is a device including a display capable of touch input, and may be a display device such as a digital signage as well as a terminal device such as a smart phone, a tablet, a wearable computer, a notebook computer and the like. In particular, the second device 120 is a device having a light source sensing means for sensing a change in light amount to the light source output from the light source output means of the first device 110 at a predetermined position of the main body, An RGB sensor, an image sensor, a camera, or the like may be used as a light sensor.

For example, the first device 110 may use the camera flash provided on the rear surface of the main body as the light source output means, and the second device 120 may use the light intensity sensor provided on the front surface of the main body as the light amount sensing means .

The first device 110 and the second device 120 may be the same kind of device or different types of devices.

As shown in FIG. 1, when the user places the first device 110 close to the second device 120 and then simply touches the display of the first device 110, 2 devices 120 can be moved.

At this time, the content moving system outputs a light source of a predetermined pattern through blinking of the camera flash in the first device 110, and then, through the illumination sensor in the second device 120, The first device 110 and the second device 120 can establish automatic coupling for content movement.

Coupling may be performed between the first device 110 and the second device 120 on the basis of the light source output and the light amount analysis, and the content 100 of the first device 110 may be coupled to the second device 120, The user can move to the device 120 or move the content 101 of the second device 120 to the first device 110.

Referring to FIGS. 3 and 4, a description will be made of a technique of moving content between devices.

3 is a block diagram showing an internal configuration of a first device and an internal configuration of a second device in an embodiment of the present invention. 3, the first device 110 according to an exemplary embodiment may include a camera flash 111, a coupling unit 112, and a content moving unit 113, 2 device 120 may include an illuminance sensor 121, a coupling unit 122, and a content moving unit 123. [

4 is a flowchart illustrating a content moving process between a first device and a second device according to an embodiment of the present invention. The content moving process according to an exemplary embodiment may be performed by the first device 110, the second device 120, and the server 130 in FIG.

In the initialization step S401, the first device 110 and the second device 120 execute a dedicated application to start a device-to-device content transfer interface or access a specific URL through a web browser, 130, respectively.

Assuming that the first device 110 and the second device 120 are connected to the server 130, the coupling unit 112 of the first device 110 performs the initialization step according to the content movement request of the user (S402) (Hereinafter, referred to as an 'interaction ID') for interaction with the server 130 through the connection according to the request (S403).

The server 130 allocates a unique ID, i.e., an interaction ID, that can distinguish the corresponding interaction, to the request of the first device 110 (S404), and transmits the assigned interaction ID to the first device 110 (S405). At this time, the interaction ID may be composed of a bit stream composed of 1 and 0. When a request for an interaction ID is randomly transmitted to the server 130 in a state where a plurality of first devices 110 and a plurality of second devices 120 are mixed, the server 130 transmits a different interaction ID Can be assigned and responded to.

The coupling unit 112 of the first device 110 can extract the interaction ID assigned by the server 130 in the response message when the response message is received from the server 130. Based on the interaction ID, And controls the camera flash 111 to generate a light source of a predetermined pattern (S406). For example, the coupling unit 112 may set the camera flash 111 to ON with respect to 1, which is the first significant bit (MSB) of 1010b, if 1010b is assigned as an interaction ID.

The coupling unit 112 of the first device 110 may broadcast a peripheral device search message to the server 130 to confirm whether the second device 120 exists within a predetermined distance The server 130 transmits the peripheral device search message to the second device 120 (S408).

When the peripheral device search message is received from the server 130, the coupling unit 122 of the second device 120 can acquire the illuminance status information detected through the illuminance sensor 121, which is the light amount sensing means, as the light amount change information (S409), and may transmit the response message to the peripheral device search message, including the illuminance status information, to the server 130 (S410). If the response message is received from the second device 120, the server 130 stores the received response message and notifies the first device 110 that the response message has been received (S411).

The coupling unit 112 of the first device 110 sets the camera flash 111 to OFF for the next bit of the interaction ID 1010b and transmits a peripheral device search message to the server 130 May collect illumination condition information from the second device 120. [ In other words, the coupling unit 112 of the first device 110 turns on / off the camera flash 111 for all bits in the interaction ID, and the server 130 transmits the light from the second device 120 So that the illuminance state information sensed through the sensor 121 can be collected.

If the above procedure (S406 to S411) is a procedure P, the procedure P can be repeated according to the bit stream length of the interaction ID. At this time, the server 130 irradiates the light source pattern by the camera flash to all bits in the interaction ID It is possible to collect illuminance status information detected by the sensor.

The server 130 may restore the interaction ID based on the illumination condition information collected from the second device 120 through all the processes (S412). For example, the server 130 may determine that the light intensity sensor value is 1 if the lightness sensor value is greater than or equal to a specific threshold value, and 0 if the lightness sensor value is less than the threshold value, and restore the interaction ID.

The server 130 can perform a task mapped to the corresponding interaction ID if the restored interaction ID based on the illumination state information of the second device 120 coincides with the previously assigned interaction ID. For example, if the touch performed by the user on the first device 110 in step S402 is a drag / sweep type touch that is performed from the top to the bottom of the display as shown in FIG. 5, The coupling unit 112 of the first device 110 may transmit the touch information including the touch type and the touch direction of the user to the server 130 in step S403 of requesting the server 130 for the interaction ID.

The server 130 determines whether or not the touch performed by the user on the first device 110 based on the touch information received from the first device 110 when assigning the interaction ID is displayed in the form of a drag / , You can map the content download operation to the corresponding interaction ID.

Accordingly, the server 130 can control the content downloading operation mapped to the interaction ID to be performed when the restored interactive ID based on the illuminance status information of the second device 120 matches the pre-assigned interaction ID.

If it is determined that the restored interaction ID is the same as the previously assigned interaction ID, the server 130 requests the interaction ID to request the coupling unit 112 of the first device 110 and the finally restored interaction ID The coupler 122 of the second device 120 that has transmitted the roughness status information is mapped to complete the coupling between the two devices (S413).

When the coupling between the first device 110 and the second device 120 is completed, the server 130 transmits the information about the task mapped to the interaction ID to the first device 110 and the second device 120 ).

The content moving unit 113 of the first device 110 and the content moving unit 123 of the second device 120 may download the content from the second device 120 to the first device 110 (Step S414). In step S414, the content is moved by expressing the content displayed on the display of the second device 120 on the display of the first device 110. FIG.

The content moving unit 113 of the first device 110 may display the content downloaded from the second device 120 on the display and notify the server 130 that the content has been moved. At this time, when the content movement is completed, the server 130 can release the occupation of the interaction ID assigned to the first device 110 (S415) so that the interaction ID can be reused for other interaction requests. That is, at the same time when the occupation of the interaction ID is released, the corresponding interaction for moving the content between the first device 110 and the second device 120 is terminated.

6, when the user performs a drag / sweep type touch performed from the bottom up on the display of the first device 110, when assigning the interaction ID, the server 130 adds the content ID You can map upload jobs. In the same manner, when the server 130 matches an interaction ID previously assigned based on the roughness state information received from the second device 120, The first device 110 and the second device 120 may be controlled to operate in such a manner that the content displayed on the display of the first device 110 is transmitted to the second device 120. [

In addition, when the user performs another type of touch such as long touch or double tap on the display of the first device 110, the control may be performed on the second device 120 according to the implementation. For example, when the user performs a long touch on the display of the first device 110 as shown in FIG. 7, the first device 110 couples with the second device 120, A remote control environment for controlling the operation of the second device 120 may be implemented. A method by which the first device 110 can control the second device 120 may include various methods such as camera control and touch control of the second device 120 by the first device 110.

In this specification, the flashing control using the camera flash of the first device and the coupling and the content movement using the illuminance sensor of the second device are described. However, the present invention can be applied to the flashing of the display and the brightness control And the same operation can be performed using an RGB sensor, an image sensor, and a camera in place of the illuminance sensor.

The present invention can perform coupling of content transmission or device control through light source control and light amount analysis between a first device and a second device. In the coupling procedure using the flashing camera flash, as shown in 1010b, the server transmits the interaction ID to the flashing of the camera flash and recognition by the illuminance sensor. If the interaction ID is long, the overall interaction time may increase proportionally .

In order to solve this problem, when a device (a first device and a second device) is connected to a server, when a public network such as 3G or LTE is used, the location information is transmitted to the server or when the WIFI is used, the SSID service set identifier to the server. At this time, the server can generate and maintain the mapping table between the device and the server with the location information or the SSID information, and when the specific device is connected, the connection can be transferred to the appropriate server based on the mapping table.

As shown in FIG. 8, when each device is connected to the WIFI and transmits the SSID information of the peripheral WIFI AP to the server (server 1), the server can generate and maintain a mapping table indicating that devices exist around each AP have. At this time, when the devices existing around the APs 1 to 5 perform the interaction, the server (server 1) assigns one of the interaction IDs when the devices perform the interaction with the interaction ID set (000b to 111b) .

Since a total of eight interaction IDs can be assigned to a set of interaction IDs, a total of 16 devices exist around the APs 1 to 5, so that even when performing simultaneous interactions, two of the 16 devices are subjected to a total of eight interactions All can assign an interaction ID. If the number of devices around AP1 ~ 5 is 16 or more, you can manage up to 32 interaction ID sets by increasing the interaction ID to 4 bits.

If the SSID transmitted by the device connecting to the server is information on the AP 6, the server can transmit information to the device to access another server (server 2) managing the AP 6. The device receives this information, (Server 2) to perform the assignment of the interaction ID and the interaction.

In this way, each server can share all the terminals using the service based on the location information or the SSID, and each server can increase or decrease the set of interaction IDs in proportion to the number of terminals to have the minimum interaction ID length It can support the interaction of all devices.

The following services may be available when each device transmits information that can identify the location, such as location information or WIFI AP SSID, to the server.

If the content of the second device is contents requiring protection of copyright such as the book or MP3, the first device moves the content of the second device to the first device, utilizes the content at a position near the second device, If the location is beyond a certain distance, the content can be automatically deleted or the area can be protected by copyright protection.

For example, it can be assumed that the first device and the second device are present at a position held by the server 1, and the second device expresses copyright content protected on the screen. At this time, the copyright is restricted so that devices can be used in unlimited number of devices only when the device is present at the position managed by the server 1, i.e., at the peripheral positions of the WIFI APs 1 to 5 or connected to the WIFI APs 1 to 5 Can be protected.

When the second device is fixed in position and connected to the WIFI AP 2 to always display the bookbook on the display and the first device accesses the corresponding location and performs the interaction to move the bookbook from the second device, Can read the contents of this book if it is connected to WIFI AP 1 ~ 5 or does not leave the vicinity of the APs.

At this time, each of the devices periodically transmits the location information to the server 1, and when the first device transmits the location information out of the location range to the server 1, the server issues a command to the first device so that the user can not read the contents of the book , It is possible to enable the use of a limited range of North Korea.

The size of the location range may vary from several tens of meters to several kilometers in terms of implementation, may include several tens of APs, and the location managed by multiple servers may be a single location range. If there are devices in a moving object such as train, bus, etc., and the position range-limited service is used, the position range may be the path of train or bus.

In a situation where content is uploaded from the first device 110 to the second device (not shown), one or more contents 100 may exist on the display of the first device 110 as shown in FIG. Also, the user may move the content 100 in the display of the first device 110 using the drag / sweep type touch performed from the bottom up, but may not want to perform content transmission to the second device.

Accordingly, the system needs to distinguish whether the user moves the location of the content in the first device 110 or the content in the first device 110 to the second device.

For example, when the user touches the content and moves or moves the touch to the border of the display or the bezel area A of the first device 110, as shown in FIG. 9, the system transmits the content to the first device 110, A gesture moving from the first device to the second device can be recognized.

At this time, the user selects multiple contents 100 to be moved from the first device 110 to the second device by multi-touch, moves the touch to the bezel A, It is possible to move a plurality of contents 100 at a time by coupling using blinking.

10, when the user performs a touch to select all contents 100 to be moved from the first device 110 to the second device and performs a drag or sweep to the bezel A, Coupling allows the user to transmit multiple content 100 at a time.

When the user takes a border of the first device 110 and a gesture for dragging / sweeping the display from the bezel area A to the inside of the display as shown in the left part of FIG. 11, the user may select one or more second devices 120-1 and 120-2 ) And can maintain the coupling. After the gesture of the user is completed, the first device 110 couples with the one or more second devices 120-1 and 120-2 through the camera flash and the coupled second devices 120 - 1, and 120 - 2 on the screen of the first device 110. At this time, the device A 120-1 and the device B 120-2 may be displayed as a coupled second device on the screen of the first device 110. [

12, the user can single-touch an icon for the device A 120-1 from the list of the second devices 120-1 and 120-2 displayed on the screen of the first device 110, In this case, the device A 120-1 recognizes the user's selection and displays the frame of the screen as a feedback signal for selection in a specific color (e.g., red color) or pattern, or reproduces vibration or sound, So that the second device selected by itself on the screen of the first device 110 is recognized as being identical to the actual device A 120-1.

The user drags the content C out of the content 100 displayed on the screen of the first device 110 as shown in FIG. 13, and transmits the content A to the device A 120- 1, the content C is moved to the actual device A 120-1.

Also, the user may be holding down the icon of the device A 120-1 from the list of the second devices 120-1 and 120-2 displayed on the screen of the first device 110. [ In this case, an icon for the first device 110 (Dev 1) appears on the screen of the device A 120-1 as shown in FIG. 14 in the actual device A 120-1, ) Is dragged toward the icon of the first device 110 displayed on the display of the device A 120-1, the content of the device A 120-1 is actually moved to the first device 110 .

In the present specification, in the method of expressing the interaction ID as a camera flash, each bit of the interaction ID is represented by on / off of the camera flash, but other methods are also possible. For example, if the interaction ID is 10b, the camera flash will display each bit of the interaction ID as ON time information in the form of ON (1.5 seconds), OFF (0.5 seconds), ON (0.5 seconds) If the camera flash can control brightness, color, etc., the brightness of the camera flash can be displayed in the form of 100% and 20% in order to express 10b. In the case of color representation, the color of white, It is also possible to express information.
