Using this, regardless of the state of the screen, the user can easily run the QR reader for location sharing at any time.

According to the examples as described above, the QR reader for location sharing may be executed. Including the above execution method, procedures for sharing location information are as follows.

4 illustrates a procedure for transmitting location information to share location information in accordance with the present invention. 4 shows an example of the operation of the first apparatus 110.

Referring to FIG. 4, the first device 110 executes a location sharing QR reader (step S401). For example, the first device 110 may execute a QR reader for location sharing according to a method as illustrated in FIGS. 3A, 3B, or 3C. As the QR reader for location sharing is executed, the camera is activated, and a preview screen shot by the camera is displayed on the screen. In addition, a guide may be further displayed on the screen requesting the location of the QR code.

Thereafter, the first device 110 obtains the location information by reading the QR code according to the user's operation (step S402). That is, when the user adjusts the camera angle and position so that the QR code is placed on the guide displayed on the first device 110, the first device 110 reads the QR code. According to another embodiment, an additional command to read the QR code may be further needed. That is, after the QR code is located in the guide, when the user inputs an additional command (for example, touch a shooting button), the QR code can be read. The first device 110 obtains the location information by analyzing the QR code according to the interpretation rule defined in the location sharing QR reader.

Subsequently, the first device 110 stores the location information in the clipboard (step S403). That is, the first device 110 temporarily stores the location information so that the location information can be pasted. Accordingly, in addition to the function of utilizing the location information provided by the QR reader for location sharing, the user may utilize the location information in various ways.

Thereafter, the first device 110 determines whether the QR reader for location sharing during the call is executed (S404). If not in a call, the first device 110 terminates this procedure. According to another embodiment, the first device 110 may automatically perform a function utilizing the acquired location information or display a list of functions.

On the other hand, if a call is in progress, the first device 110 displays a screen for inquiring whether to transmit location information to the other party in the call (S405). The screen for inquiring whether to send the location information includes a text informing the user of the inquiry (eg, "Do you want to send the location information to the person you are calling?") And a button for inputting the selection result (eg "Yes", "No" ) May be included. That is, the first device 110 displays one option for the processing of the location information. Accordingly, the user can share the location information or stop sharing the location information without further manipulation.

Next, the first device 110 determines whether the user approves (S406). If the user does not approve, for example, if it is confirmed that the user selects the NO button, the first device 110 ends the procedure.

On the other hand, if the user approves, the first device 110 transmits the location information to the other party in the call (S407). That is, the first device 110 connects to a wireless network, establishes a connection, generates a packet including location information, and then transmits the packet to the device (eg, the second device 120) of the other party. As such, the user can easily share the location information during the call by executing and approving the QR reader for location sharing during the call.

In the embodiment described with reference to FIG. 5, some steps may be omitted. For example, steps S405 and S406 may be omitted, and the first device 110 may directly transmit the location information to the other party on the call after obtaining the location information. In this case, according to another exemplary embodiment, the first device 110 may further display a notification text indicating that the location information is transmitted according to the QR code reading before the QR code reading when the QR reader for location sharing is executed. Notification text may be displayed with a guide requesting the location of the QR code.

In the embodiment described with reference to FIG. 5, when not in a call, the first device 110 may automatically perform a function utilizing the acquired location information or display a list of functions. Alternatively, according to another embodiment, the first device 110 may display options for two or more ways of transmitting the location information, and transmit the location information to the other device according to the option selected by the user. That is, the first device 110 may display a screen for inquiring selection of a method of processing location information. For example, options may include sending in a text message, sending in a messenger program, sending in email, saving to a clipboard, and the like.

5 illustrates a procedure for receiving location information to share location information in accordance with the present invention. 5 shows an example of the operation of the second device 120.

Referring to FIG. 5, the second device 120 receives location information generated by the QR reader for location sharing (step S501). Location information may be received in the form of a push message.

Subsequently, the second device 120 executes the QR reader for location sharing (step S502). Here, the QR reader for location sharing may be automatically executed according to the reception of the location information. According to another embodiment of the present disclosure, the second device 120 may display a notification on the location information and execute a location sharing QR reader in response to a user's selection.

Thereafter, the second device 120 displays options for using location information (step S503). For example, the options may include navigating to a location indicated by the location information, copying the location information to the clipboard, and the like. In addition, when other information is added to the location information, an option using the other information may be further displayed. For example, when a webpage address (eg, a homepage of a restaurant, a blog, etc.) of a place is received in addition to the location information, access to the webpage may be further displayed as an option.

Subsequently, the second device 120 performs an operation according to the user's selection (S504). To this end, the second device 120 may execute another application (eg, a navigation application) according to the selected option. For example, when the user selects a navigation service, the second device 120 may execute a navigation application, set a location indicated by the received location information as a destination, and then perform a road guide. Alternatively, when the user selects to access the homepage, the second device 120 may execute a web browser application and access a site of the confirmed webpage address.

As described above, the device may read the QR code to obtain the location information and transmit it to another device. The chain of actions following the reading of the QR code enhances the user's convenience for location sharing. That is, the user can easily check the location, input or copy the location information, perform an application such as a messenger or text to share, paste the copied information, and command the transmission without complicated operations. Location information can be shared with the other party. The chain of operation procedures that provide this effect can be performed by a dedicated application. Alternatively, the chain operation procedure may be derived by a QR code according to the grammar designed as follows.

Items constituting the QR code according to an embodiment of the present invention are divided into identifiers and contents. The identifier is further divided into a 'type identifier' indicating the type of information and an 'action identifier' specifying a function / application to be executed. The contents are divided into 'data' including information of the type designated by the type identifier, and 'execution command' specifying the operation of the function / application designated by the action identifier.

Type identifiers are separated by character, followed by the content. The type identifier is followed by the type of data specified by that type identifier. For example, a sequence may be written as "LOCATION: xx to yy, Gangnam-gu, Seoul." Here, ':' is an example of a character representing a type identifier.

Two or more type identifiers and pairs of data may be contained in one QR code. For example, if an address and a website address are included, "LOCATION: xx to xx, Gangnam-gu, Seoul; URL: http: //○○○.co.kr "may be created. here '; 'Is an example of a character that indicates the start of a new type identifier.

The action identifier includes a string representing the action identifier and a string representing the type of the action. For example, when specifying a function indicating short messaging service (SMS) transmission, the action identifier may be written as "ACTION_SMS". Further, in the case of specifying that the other party is transmitting the location information through SMS, the sequence may be created as "ACTION_SMS: send $ LOCATION to #caller". Here, '$' is a character indicating that the variable obtained through the QR code, '#' is a character indicating that the variable should be read from the outside.

to be. Multiple pairs of action identifiers and execution instructions may be included in the QR code. If the read QR code contains a plurality of pairs of action identifiers and execution commands, the device may display a list of functions corresponding to each action identifier and execute any one selected by the user.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention.
