3 to 22 are views for explaining a method of interworking between a guest terminal and a host terminal. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 3, when the host terminal 100 and the guest terminal 200 recognize each other (S300), the host terminal 100 and the guest terminal 200 can be interlocked (S310).

Thereafter, when the host terminal 100 and the guest terminal 200 are interlocked, the input window IPS corresponding to the host terminal 100 is displayed on the screen of the display unit 251 of the guest terminal 200 (S320) .

In step S330, it is determined whether predetermined information is input to the input window IPS. When information is input to the input window IPS as a result of the determination, the guest terminal 200 inputs To the host terminal 100 (S350).

Thereafter, it is possible to determine whether the user inputs a transmission command to the guest terminal 200 (S350). If the user inputs a transmission command to the guest terminal 200, the host terminal 100 may transmit the information displayed in the input window IPS to the outside (S360).

An example of a method in which the host terminal 100 and the guest terminal 200 recognize each other is the same as in the case of FIG. 4 to FIG.

Referring to FIG. 4, the host terminal 100 may detect the guest terminal 200 (S600).

Then, the host terminal 100 can transmit a predetermined first signal (S601) to the guest terminal 200 for recognition. Here, the first signal may be a signal for inquiring whether or not the guest terminal 200 can interoperate with the host terminal 100.

Then, the guest terminal 200 receives the first signal transmitted from the host terminal 100, and transmits the second signal as the response signal corresponding to the first signal to the host terminal 100 (S602 )can do.

Here, the second signal may be a signal corresponding to an answer that the guest terminal 200 can be interlocked with the host terminal 100.

Then, the host terminal 100 can recognize (S300) the guest terminal 200 based on the second signal. In addition, the guest terminal 200 can recognize the host terminal 100 based on the first signal (S300).

Accordingly, the host terminal 100 and the guest terminal 200 can be interlocked (S310).

5, the guest terminal 200 may detect the host terminal 100 (S610).

Thereafter, the guest terminal 200 may transmit a predetermined third signal (S611) to the host terminal 100 for recognition. Then, the host terminal 100 receives the third signal transmitted from the guest terminal 200, and transmits the fourth signal (Fourth Signal) as the response signal corresponding to the third signal to the guest terminal 200 (S612 )can do.

Then, the guest terminal 200 can recognize the host terminal 100 based on the fourth signal (S300). In addition, the host terminal 100 can recognize the guest terminal 200 based on the third signal (S300).

Accordingly, the host terminal 100 and the guest terminal 200 can be interlocked (S310).

When the host terminal 100 and the guest terminal 200 are interlocked with each other as described above, an input window (IPS) can be displayed on the screen DS2 of the guest terminal 200, as in the case of FIG. For example, a pop-up screen type input window (IPS) may be displayed on the screen DS2 of the guest terminal 200.

Here, the size of the screen DS2 of the guest terminal 200 may be larger than the size of the screen DS1 of the host terminal 100. [ In other words, the size of the display unit 251 of the guest terminal 200 may be larger than the size of the display unit 151 of the host terminal 100.

The interworking of the guest terminal 200 and the host terminal 100 may be determined depending on the distance between the guest terminal 200 and the host terminal 100. [

For example, when the host terminal 100 is located within the radius R from the guest terminal 200 as in the case of FIG. 7A, the host terminal 100 and the guest terminal 200 are connected to the guest terminal 200 An input window (IPS) corresponding to the host terminal 100 may be displayed on the screen of the terminal 200. [

On the other hand, when the host terminal 100 is located outside the radius R from the guest terminal 200 as in the case of FIG. 7B, the host terminal 100 and the guest terminal 200 are not interlocked .

That is, when the guest terminal 200 is located within the predetermined threshold range from the host terminal 100, it is possible to display the input window corresponding to the host terminal 100 on the screen of the guest terminal 200. [

On the other hand, before the input window (IPS) is displayed on the screen of the guest terminal 200, alarm (Alram) information for notifying the interworking of the host terminal 100 and the guest terminal 200 is displayed on the screen of the guest terminal 200 Can be displayed.

The alarm information ALM can be displayed on the screen DS2 of the guest terminal 200 when the host terminal 100 and the guest terminal 200 are interlocked as in the case of Fig. have.

8 (B), when the user selects the alarm information ALM by using the cursor CS, etc. as in the case of FIG. 8 (C) It is possible to display the input window IPS on the screen DS2 of the guest terminal 200. [

That is, when the host terminal 100 and the guest terminal 200 are linked, the screen DS2 of the guest terminal 200 is displayed on the screen DS2 of the guest terminal 200 before the input window IPS is displayed on the screen DS2 of the guest terminal 200 Displays the alarm information ALM and displays the input window IPS on the screen DS2 of the guest terminal 200 when the user selects the alarm information ALM.

The alarm information (ALM) can be changed to various types. For example, the alarm information ALM may be an icon corresponding to the form of the host terminal 100. [

Alternatively, the alarm information (ALM) may be displayed on the task bar of the guest terminal 200.

Alternatively, the alarm information ALM may be displayed in a blinking type on the screen DS2 of the guest terminal 200. [

Alternatively, it is also possible to display the alarm information (ALM) on the screen DS2 of the guest terminal 200 and additionally to alarm with the sound output module 252 by voice.

8C shows an example in which an input window IPS is displayed on a partial area of the screen DS2 of the guest terminal 200. The input window IPS is used to display the guest terminal 200, Can be displayed on the entire screen DS2 of the display screen DS2. That is, the input window (IPS) can be displayed in full screen on the guest terminal 200.

On the other hand, an authentication information input window for inputting authentication information may be displayed before the input window (IPS) is displayed on the screen of the guest terminal 200.

More specifically, as shown in FIG. 9, when the host terminal 100 and the guest terminal 200 are linked, an authentication information input window for inputting authentication information on the screen of the guest terminal 200 can be displayed (S900) have.

For example, when the host terminal 100 and the guest terminal 200 are interlocked as shown in Fig. 10A, the alarm information ALM is displayed on the screen DS2 of the guest terminal 200 When the user selects the alarm information ALM, authentication information, for example, authentication information for inputting a password is input to the screen DS2 of the guest terminal 200 as in the case of FIG. 10B A window (IDS) can be displayed.

Thereafter, when the user inputs the authentication information into the authentication information input window (S910), it can be determined whether or not the input authentication information matches the information corresponding to the host terminal 100 (S920).

As a result of the determination, if the user agrees with the information input in the authentication information input window and the information corresponding to the host terminal 100, the input window (IPS) can be displayed on the screen of the guest terminal 200 (S320).

In order to determine whether or not the information entered by the user into the authentication information input window (IDS) displayed on the guest terminal 200 matches the information of the host terminal 100, the memory 260 of the guest terminal 200 It may be desirable to store the authentication information of the host terminal 100. [

Alternatively, when the user inputs the authentication information into the authentication information input window (IDS) displayed on the guest terminal 200, the guest terminal 200 can transmit the information inputted by the user to the host terminal 100. [ In this case, the host terminal 100 transmits a signal for confirming the authentication information inputted by the user as matching information to the guest terminal 200, and correspondingly, the guest terminal 200 displays an input window (IPS) on the screen It is also possible to display.

11, an input window (IPS) displayed on the guest terminal 200 includes a text input window 1110 and a reception number input window 1100 for inputting an incoming telephone number A transmission input window 1120 for inputting a transmission command for transmitting information to a terminal corresponding to the telephone number entered in the reception number input window, and a contact search window 1130 for searching for a previously stored contact It is possible.

The contact search window 1130 may be linked to the contact stored in the memory 260 of the guest terminal 200 or may be linked to the contact stored in the memory 160 of the host terminal 100. [ Accordingly, the user can search for the contact stored in the memory 160 of the host terminal 100 by selecting the contact search window 1130, and search for the contact stored in the memory 260 of the guest terminal 200 May be possible.

A number 1190, which is not described in FIG. 11, may be a keyboard included in the user input unit 230 of the guest terminal 200.

Alternatively, as in the case of FIG. 12, the input window (IPS) may include a recent record search window 1200 for searching for recent use records, a storage selection window 1210 for storing contacts, memos, It is also possible to include more.

Such an input window (IPS) can be variously changed. For example, the input window (IPS) may further include a voice selection window for selecting voice information input.

The guest terminal 200 automatically transmits the information input to the input window IPS to the host terminal 100 in conjunction with the input of the predetermined information into the input window IPS displayed on the guest terminal 200, Lt; / RTI >

For example, when a predetermined first character string is input to the text input window 1110 of the input window (IPS) displayed on the screen DS2 of the guest terminal 200, as in the case of (A) , The guest terminal 200 may automatically transmit the first character string to the host terminal 100. Here, the user may input the first character string into the text input window 1110 using the keyboard of the guest terminal 200. [

13 (B), a text input window 1310 is displayed on the screen DS1 of the host terminal 100, and the text input window 1310 is displayed on the screen DS1 of the host terminal 100. In this case, It is possible to display one string.

Accordingly, the user can check the string input from the guest terminal 200 from the host terminal 100 as well.

The telephone number input by the user into the reception number input window 1100 of the input window IPS of the guest terminal 200 is also input to the reception number input window 1300 displayed on the screen DS1 of the host terminal 100 Can be displayed.

13B is a transmission input window 1320 for inputting a transmission command for transmitting information to a terminal corresponding to the telephone number input in the reception number input window, And a contact search window 1330 for searching for contacts.

Herein, the user not only stores the contacts stored in the memory 160 of the host terminal 100 but also the memory 260 of the guest terminal 200 using the contact search window 1330 displayed on the screen DS1 of the host terminal 100, It may be possible to search for a contact stored in the database.

In this case, the user can select the outgoing input window 1120 in the input window (IPS) of the guest terminal 200. The guest terminal 200 transmits a transmission command to the host terminal 100 and the host terminal 100 transmits the telephone number input in the reception number input window 1100 of the guest terminal 200, The text input to the text input window 1110 can be transmitted to the terminal corresponding to the text input window 1166. [

In this manner, the host terminal 100 and the guest terminal 200 are interlocked with each other and information such as text is input to the input window IPS displayed on the screen DS2 of the guest terminal 200 adjacent to the host terminal 100 , And can transmit it to the outside through the host terminal 100. Accordingly, the host terminal 100 can be easily used.

For example, when the host terminal 100 is operated independently as shown in FIG. 13B, the size of the text input window 1310 is relatively small and the size of the host terminal 100 is relatively small Often, a character string input to the text input window 1310 may be mistakenly generated. In addition, a malfunction of the host terminal 100 may frequently occur due to a user's touch error or the like.

On the other hand, when the user has a relatively large screen size and operates the host terminal 100 using the guest terminal 200 having an input means such as a keyboard, the size of the host terminal 100 is relatively small The occurrence of a malfunction of the host terminal 100 can be suppressed even in a small case. For example, a user who uses a notebook computer (guest terminal 200) can receive text information received by a smart phone from a notebook computer (personal computer) while keeping his or her smart phone (host terminal 100) And it is also possible to easily transmit text using a notebook computer without directly operating the smart phone.

In consideration of this, the host terminal 100 may be a mobile communication terminal, a guest terminal 200, a notebook computer, or a desktop computer.

When the user inputs a predetermined character string to the host terminal 100, the information input to the host terminal 100 is transmitted to the guest terminal 200 and displayed on the input window IPS of the guest terminal 200 .

For example, when a predetermined second character string is input to the text input window 1310 displayed on the screen DS1 of the host terminal 100, as in the case of Fig. 14A, The guest terminal 200 can automatically transmit the second character string to the guest terminal 200. The user can input the second character string into the text input window 1310 using the character window 1400 displayed on the screen DS1 of the host terminal 100. [ To this end, the user can use a mouse or the like or use a touch means.

14B, the second character string sent from the host terminal 100 is displayed in the text input window 1110 of the input window IPS displayed on the screen DS2 of the guest terminal 200 It is possible to do.

Accordingly, the user can check the character string input from the host terminal 100 in the guest terminal 200 as well.

Meanwhile, when a predetermined event occurs in the host terminal 100 while the guest terminal 200 and the host terminal 100 are interlocked, an input window (IPS) is displayed on the screen of the guest terminal 200 It is possible to do.

For example, as in the case of FIG. 15, when the host terminal 100 and the guest terminal 200 are interlocked (S310), it is possible to determine whether or not an event has occurred in the host terminal 100 (S1500).

As a result of the determination, if an event occurs in the host terminal 100, the input window (IPS) can be displayed on the screen of the guest terminal 200.

It is also possible to display the alarm information ALM on the screen of the guest terminal 200, as in the case of FIG. 8, when the host terminal 100 generates an event. This can be sufficiently replaced with the description of FIG. 8, and thus redundant description will be omitted.

It is also possible to display an authentication information input window (IDS) on the screen of the guest terminal 200, as in the case of FIGS. 9 to 10, when an event occurs in the host terminal 100 have. This can be sufficiently replaced with the description of FIGS. 9 to 10, and thus redundant description will be omitted.

An event occurring in the host terminal 100 may include the reception of text and / or voice information, the reception of a call, the movement of the host terminal 100, the touch of the host terminal 100, And so on.

For example, as in the case of FIG. 16A, if no event is generated in the host terminal 100, the input window (IPS) may not be displayed in the guest terminal 200 as well.

On the other hand, when the user operates the host terminal 100 to display the text input window 1310 on the screen DS1 of the host terminal 100 as in the case of FIG. 16B, the guest terminal An input window IPS may be displayed on the screen DS2 of the display unit 200. [

If the user closes the text input window 1310 in the host terminal 100 in the state of FIG. 16B, the input window IPS disappears from the screen DS2 of the guest terminal 200 .

Meanwhile, when there are a plurality of host terminals 200 corresponding to one guest terminal 200, an input window (IPS) corresponding to at least one host terminal 200 in which a plurality of events occurred in the plurality of host terminals 200 Can be displayed on the screen of the guest terminal (200).

For example, assume that the first, second, and third host terminals 100A, 100B, and 100C are located in the radius R area from the guest terminal 200, as in the case of FIG.

In this case, as shown in FIG. 18, the guest terminal 200 and the first, second and third host terminals 100A, 100B and 100C may be interlocked with each other (S310).

Thereafter, it may be determined whether there is a terminal in which a predetermined event occurs among a plurality of host terminals 100A, 100B, and 100C (S1800).

As a result of the determination, if there is a terminal in which an event has occurred, the terminal on which the event has occurred is confirmed (S1810), and an input window (IPS) corresponding to the terminal can be displayed on the screen of the guest terminal 200. [ The types of events have been described above.

Alternatively, it may be possible to display the authentication information input window (IDS) and / or the alarm information (ALM) before displaying the input window on the guest terminal 200. [

For example, when an event such as a character is received at the first host terminal 100A among the first, second and third host terminals 100A, 100B, and 100C occurs, The corresponding alarm information (ALM) and / or the authentication information input window (IDS) can be displayed on the screen of the guest terminal 200. Such a configuration can be sufficiently inferred from Figs. 8 to 10. Fig.

Alternatively, although not shown, it is also possible to display alarm information corresponding to the first, second, and third host terminals 100A, 100B, and 100C, respectively, in the guest terminal 200. [ In this case, an input window (IPS) is displayed on the screen of the guest terminal 200 corresponding to the host terminal corresponding to the alarm information selected by the user among the alarm information corresponding to the first, second, and third host terminals 100A, 100B, Or an authentication information input window (IDS) corresponding to the host terminal corresponding to the alarm information selected by the user can be displayed.

A case where a plurality of guest terminals 200 correspond to one host terminal 100 will be described below.

For example, when the first, second, and third guest terminals 200A, 200B, and 200C are linked to one host terminal 100 as in the case of FIG. 19, An input window (IPS) corresponding to the host terminal 100 may be displayed on the screen of the guest terminal 200A.

19 shows that the interval D1 between the first guest terminal 200A and the host terminal 100 is shorter than the interval D2 between the second guest terminal 200B and the host terminal 100 and the interval D2 between the third guest terminal 200C and the host terminal 100. [ And the distance D3 between the host terminal 100 and the host terminal 100. [

Alternatively, it is possible to display an authentication information input window corresponding to the host terminal 100 in each of the plurality of guest terminals 200A, 200B and 200C.

20, when the guest terminal 200 and the host terminal 100 are interlocked, it is determined whether or not the number of the guest terminals 200 linked to the host terminal 100 is plural (that is, S2100).

As a result of the determination, if the number of the guest terminals 200 linked to the host terminal 100 is one, an authentication information input window for inputting authentication information on the screen of the guest terminal 200 may be displayed (S900) .

Thereafter, when the user inputs the authentication information into the authentication information input window (S910), it can be determined whether or not the input authentication information matches the information corresponding to the host terminal 100 (S920).

As a result of the determination, if the user agrees with the information input in the authentication information input window and the information corresponding to the host terminal 100, the input window (IPS) can be displayed on the screen of the guest terminal 200 (S320).

On the other hand, if it is determined in step S2100 that there are a plurality of guest terminals 200 linked to the host terminal 100, an authentication information input window for inputting authentication information on the screens of the plurality of guest terminals 200 Respectively (S2110).

Thereafter, when the user inputs the authentication information into the predetermined authentication information input window, it can be determined whether or not the input authentication information matches the information corresponding to the host terminal 100 (S2120).

As a result of the determination, the guest terminal 200 that has input the authentication information matching the information corresponding to the host terminal 100 can be confirmed (S2130).

Thereafter, the input window (IPS) may be displayed on the screen of the guest terminal 200 that has input the authentication information matching the information corresponding to the host terminal 100 (S320).

For example, assume that first, second, and third guest terminals 200A, 200B, and 200C are linked to one host terminal 100. [

In this case, each of the first, second, and third guest terminals 200A, 200B, and 200C can display an authentication information input window (IDS) for inputting authentication information.

Here, the first user inputs the first authentication information to the first guest terminal 200A, the second user inputs the second authentication information to the second guest terminal 200B, the third user inputs the second authentication information to the third guest terminal 200B, The third authentication information can be input to the second authentication unit 200C.

When the first authentication information among the first, second, and third authentication information matches the information corresponding to the host terminal 100, the host terminal 100 is notified to the first guest terminal 200A to which the first authentication information is input And the input window (IPS) can be displayed on the screen of the first guest terminal 200A.

Or when a plurality of guest terminals 200 are linked to one host terminal 100, an input window (IPS) may be displayed on the guest terminal 200 in the order of selecting alarm information.

21, when the guest terminal 200 and the host terminal 100 are interlocked (S310), it is determined whether the number of the guest terminals 200 linked to the host terminal 100 is plural (S2000).

As a result of the determination, when there are a plurality of guest terminals 200 linked to the host terminal 100, the alarm information can be displayed on the screens of the plurality of guest terminals 200 (S2010).

Then, the guest terminal 200 having the earliest selection of alarm information among the plurality of guest terminals 200 is given control right (S2020), and an input window (IPS) is displayed on the screen of the guest terminal 200 (S320).

In addition, the alarm information displayed on the screen of the remaining guest terminal 200 can be deleted.

Alternatively, when a plurality of guest terminals 200 are linked to one host terminal 100, an input window (IPS) may be displayed on the guest terminal 200 according to the order of selecting alarm information and the input authentication information .

22, when the guest terminal 200 and the host terminal 100 are interlocked (S310), it is determined whether the number of the guest terminals 200 linked to the host terminal 100 is plural (S2200).

As a result of the determination, if the number of the guest terminals 200 linked to the host terminal 100 is one, an authentication information input window for inputting authentication information on the screen of the guest terminal 200 may be displayed (S900) .

Thereafter, when the user inputs the authentication information into the authentication information input window (S910), it can be determined whether or not the input authentication information matches the information corresponding to the host terminal 100 (S920).

As a result of the determination, if the user agrees with the information input in the authentication information input window and the information corresponding to the host terminal 100, the input window (IPS) can be displayed on the screen of the guest terminal 200 (S320).
