It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

2 is a view schematically showing a method of transmitting and receiving information using visible light wireless communication in a mobile terminal according to the present invention.

As shown in FIG. 2, a plurality of objects 133, 134, and 135 may be provided adjacent to the road. Here, the objects 133, 134, and 135 may be, for example, a store, a department store, a movie theater, a company, a hospital, a bookstore, a library, a school,

Each of the objects 133, 134, and 135 may include Li-Fi transceivers 133a, 134a, and 135a capable of transmitting and receiving data and information using visible light wireless communication.

For convenience of explanation, it is assumed that the objects 133, 134, and 135 are shops.

Each store can transmit detailed information about the store via the Li-Fi transceiver 133a, 134a, 135a.

Each store can always transmit corresponding information via the Li-Fi transceiver 133a, 134a, 135a.

For example, if the store is a restaurant, detailed information includes a food menu, the price of the food, the country of origin of the food, the internal structure of the restaurant, the location of the toilet, and the telephone number.

For example, when a user having the mobile terminal passes through the first shop 133, the mobile terminal can receive the information provided from the first shop 133 and display it on the touch screen 151. [ Therefore, the user can be positioned in the light irradiation direction of the Li-Fi transceivers 133a, 134a, and 135a provided in the first store.

Since the Li-Fi transceivers 133a, 134a and 135a can transmit and receive data and information using light, the user must be positioned within the range of the light irradiated from the Li-Fi transceivers 133a, 134a, and 135a, Fi transceivers 133a, 134a, and 135a may be received at the mobile terminal owned by the user.

For example, if a user who has a mobile terminal passes through the first store and enters the second store 134, the mobile terminal can receive information displayed from the second store and display the information on the touch screen 151.

For example, if the user who has the mobile terminal moves into the third shop 135 after passing through the second shop, the mobile terminal can receive the information provided from the third store and display the information on the touch screen 151.

According to the present invention, since the user can receive and view information provided by each shop using visible light wireless communication without entering each store, the convenience of the user can be improved.

On the other hand, when the store receives a request from the mobile terminal through the Li-Fi transceiver 133a, 134a, or 135a, it can take necessary actions in response to the request.

For example, when an order request is received from a mobile terminal, the store can make a food ordered by the user in response to the order request.

For example, when an item is searched at the shop and an order request is received from the mobile terminal, the shop can package the item ordered by the user.

According to the present invention, a user can make a request to a store using visible light wireless communication, if necessary, so that a measure corresponding to the request can be performed, thereby improving the convenience of the user.

According to the present invention, the information received from the shop can be registered, and the information of the shop can be confirmed at any time.

According to the present invention, it is possible to perform an editing function such as newly registering information of a corresponding shop or deleting previously registered information.

As shown in FIG. 2, when the objects 133, 134, and 135 are positioned adjacent to each other, the light irradiated from each of the objects 133, 134, and 135 is superimposed. In this case, when information is received from all of at least two adjacent objects 133, 134, and 135, the mobile terminal can not confirm which information is provided at which object 133, 134, 135.

To solve this problem, each object 133, 134, 135 includes a unique identification waveform of each object 133, 134, 135 to the frequency of the light irradiated through the Li-Fi transceiver 133a, 134a, 135a .

As shown in FIG. 11, the mobile terminal receives a unique identification waveform of the corresponding object 133, 134, 135 from the corresponding object 133, 134, 135 during the initial connection period, , 134, and 135, respectively.

In addition, the mobile terminal may receive a unique identification waveform provided from the objects 133, 134, and 135 in the middle of transmitting and receiving data or information.

The unique identification waveform may be different for each object 133, 134, 135. Since the unique identification waveforms of the respective objects 133, 134 and 135 are different from each other, the mobile terminal can recognize that the data or information are not identical to any of the objects 133, 134, and 135 based on the unique identification waveforms of the objects 133, 135, or whether the communication with the object 133, 134, 135 is well maintained.

For example, the objects 133, 134, and 135 and the mobile terminal may be synchronized based on the frequency or time included in the unique identification waveform.

With this unique identification waveform, light irradiated from each of the adjacent objects 133, 134, and 135 overlaps with each other, and even if a user's mobile terminal is located in the overlapped area, specific objects can be distinguished.

3 is a flowchart illustrating a method of registering object information in a mobile terminal according to the present invention.

The object may be, for example, a store, a department store, a movie theater, a company, a hospital, a bookstore, a library, a school, a public institution, etc., as described above.

Referring to FIGS. 1 and 3, the controller 180 of the mobile terminal may activate the visible light wireless communication (S211). The activation of the visible light wireless communication may be a state in which the Li-Fi transceiver 125 is activated and power is supplied to the Li-Fi transceiver to transmit and receive information.

The control unit 180 can confirm whether the reception of information using the visible light wireless communication is automatically set (S213).

If it is not automatically set, that is, if it is manually set, the control unit 180 can display an acknowledgment window on the touch screen 151 (S215).

For example, the acknowledgment window may include an acknowledge button or a minimum button.

The control unit 180 can confirm whether the reception of the information is approved (S217). This approval may be made by a touch gesture for the approval button.

If the reception of the information is not permitted and is minimized, the control unit 180 may not receive the information provided by the object (S219).

For example, the information provided by the object may be intercepted by the Li-Fi transceiver 125.

As another example, although the Li-Fi transceiver 125 receives information provided by the object, the control unit 180 may not display the received information on the touch screen 151. [

On the other hand, when the reception of the information is automatically set in S213, the controller 180 can display the object information on the touch screen 151 (S221).

The displayed object information may be registered in the memory 170 under the control of the controller 180 (S223).

The object information registration method described above will be described in more detail with reference to FIGS.

First, there are various methods of activating the visible light wireless communication.

4A, when a touch gesture for the setting icon 301 displayed on the touch screen 151 of the mobile terminal is input, as shown in FIG. 4B, a Wi- Fi item, a Bluetooth item, a Li-Fi item 303, and the like may be displayed.

If it is set to ON for the Li-Fi item 303 among them, the visible light wireless communication can be activated.

As a second example, the status bar 305 may be positioned above the touch screen 151 of the mobile terminal, as shown in FIG. 5A.

When the touch and drag gesture for the status bar 305 is input in the downward direction, at least one icon included in the status bar may be displayed while the status bar 305 is opened as shown in FIG. 5B.

At least one or more icons included in the status bar can be directly executed when the corresponding icon is touched.

At least one or more icons included in the status bar may include, for example, a sound control icon, a Wi-Fi icon, a Li-Fi icon 307, a rotation icon, a position information icon, and an airplane mode icon.

Among them, when the touch gesture for the Li-Fi icon 307 is input, the visible light wireless communication can be activated.

As shown in FIG. 6, when a gesture for blocking the Li-Fi transceiver 125 disposed in the mobile terminal is input for a predetermined time, visible light wireless communication can be activated.

Visible light wireless communication can be activated when the Li-Fi transceiver 125 is blocked by a non-human finger or the like. However, the light reception amount received by the Li-Fi transceiver 125 may be different when the finger is blocked by the user's finger or is blocked by the object. Errors in the activation of the visible light wireless communication can be prevented by using the difference of these variations.

FIG. 7 is an exemplary diagram for explaining an object information registration method when information reception is automatically set; FIG.

Fig. 7 can correspond to S213, S221 and S223 in Fig.

As shown in FIG. 7A, when information reception is automatically set, the information provided from the object may be received and displayed on the touch screen 151. FIG.

The information may be displayed on the touch screen 151 as a pop-up window 309 or displayed on the entire area of the touch screen 151. [

The pop-up window 309 may include a registration button 311 and a cancel button.

If a selection command for the registration button 311 is input, the registration list window 313 can be displayed.

The registration list window 313 may also be displayed as a pop-up window, but this is not limiting.

The order of registration of objects in the registration list window 313 may be sequential, but is not limited thereto.

For example, when no object has yet been registered in the registration list window 313, the corresponding object information can be registered in the registration list window 313 in item 1.

For example, in the corresponding item of the registration list window 313, the business name of the object may be displayed. If a touch gesture for the business name of the object displayed in the item is input, detailed information about the object can be displayed.

8 is a diagram illustrating an example of a screen for explaining an object information registration method when information reception is manually set.

Fig. 8 can correspond to S213 to S219 in Fig.

As shown in Fig. 8, when information reception is manually set, an acknowledgment window 315 can be displayed.

The reception confirmation window 315 may include, for example, a message " Would you like to receive information?

At this time, if a selection command for the cancel button 319 included in the reception confirmation window 315 is inputted, the information provided by the object is not received or displayed on the touch screen 151.

If the selection command for the approval button 317 included in the reception confirmation window 315 is input, the information provided by the object is displayed on the touch screen 151 (see FIG. 7A) May be registered in the memory 170 (see Fig. 7B).

9 is a flowchart illustrating a method of using object information previously registered in a mobile terminal according to the present invention.

Referring to FIGS. 1 and 9, the controller 180 may register the object information received from the object in the memory 170 (S231).

The registration process of the object information described in S231 is the same as that of S223 of Fig.

If the user passes the object again (S233), the control unit 180 may display the previously registered object information on the touch screen 151 (S235).

If previously registered object information is deleted, even if the user passes the object again, the corresponding object information is not displayed.

On the other hand, when the user does not pass the object but wants to view the pre-registered object information, the registration list window (see FIG. 7B) may be displayed in response to the user's request. If the corresponding object included in the registration list window is selected (S237), the object information of the corresponding object registered in the memory 170 may be displayed on the touch screen 151 (S239).

For example, the pre-registered object information may be web information provided by the object, for example, home page information. In this case, when the corresponding object included in the registration list window (see FIG. 7B) is selected, the corresponding object is accessed through the wireless Internet module 114, and homepage information provided by the object is received and displayed on the touch screen 151 Can be displayed.

The user can generate and set the object icon so that the user can download the information provided by the object or connect to the object via the Internet through the corresponding home page information and displayed on the touch screen 151. [

10 is a diagram for explaining a method of deleting corresponding object information in the registration list window.

As shown in Fig. 10A, in response to a user's request, e.g., the execution of a Li-Fi dedicated icon, an information list window 321 may be displayed on the touch screen 151. [

For example, seven items are included in the information list window 321, object information is registered in the first to third items, and object information is not yet registered in the fourth to seventh items.

In this case, when the long touch gesture is input to the third item 323, the corresponding object information registered in the third item 323 may be deleted as shown in FIG. 10B.

In this case, the object information registered in the fourth item located under the third item 323 may be changed and registered as the third item 323.

In the drawing, since there is no object information in which the fourth item is registered, the third item 323 can be maintained in an unregistered state.

If the object information for another object is newly registered, the new object information can be registered in the third item 323.

As another example, if the number of past passes based on the number of times the same object has been passed for a certain period of time, for example, one month, is not more than the reference number, the previously registered corresponding object information may be deleted automatically. The information list window is displayed (see FIG. 10A), and the corresponding object information included in the information list window can be deleted (refer to FIG. 10B).

FIG. 12 is a diagram illustrating an information registration process in detail.

Figure 12 is similar to Figures 7 and 8 already described, but may be an example that is different from Figures 7 and 8.

As shown in FIG. 12A, a first screen 321 for requesting information reception can be displayed.

For example, when a user passes a specific object in a state in which visible light wireless communication of a mobile terminal possessed by a user is activated, a first screen 321 for confirming whether to receive information provided to a specific object, such as a hospital, is displayed .

On the first screen 321, whether to receive information and simple introduction information of the object can be displayed.

When receiving information of the object is allowed, a second screen 323 including detailed information provided by the object may be displayed as shown in FIG. 12B.

For example, there are detailed information about hospitals, detailed introduction of hospitals, main hospital business, number of hospital rooms, professor rounds, professor consultation hours, hospital location information, customer evaluation, overseas activities, and other information.

If there is a registration request from the user, the information of the corresponding object can be registered as shown in FIG. 12C. In this case, the registration list window in which the corresponding information is registered may be displayed as the third screen 325, but the present invention is not limited thereto.

If several hospitals are registered, the two hospitals can be set as emergency hospitals, and the hospitals set as emergency can be distinguished from other hospitals. Here, the hospital set as emergency can be a hospital where the user is hospitalized if the user is suddenly injured.

For example, the emergency setting hospital may be of a higher or higher type than the other hospitals.

Alternatively, the emergency setting hospital may flicker periodically.

At least one screen of the first to third screens 321, 323, and 325 may be displayed as a pop-up window, but the present invention is not limited thereto.

13 is a diagram illustrating a screen for explaining a method of informing an acquaintance or a friend of an emergency through an emergency hospital.

As shown in FIG. 13A, when an emergency occurs, the emergency situation can be informed to a friend or a friend through the information list window 331. FIG.

That is, the information list window 331 may be displayed in response to a request from the user.

At least one hospital can be registered in the information list window 331, and one of the hospitals can be set as an emergency.

In addition, the notify button 332 may be displayed next to the emergency setting hospital.

When the informing button 332 is selected, the detailed information 333 of the emergency setting hospital can be displayed on the mobile terminal 400 having a predetermined friend or acquaintance as shown in FIG. 13B.

Detailed information may be displayed in a pop-up window, but is not limited thereto.

When the notify button 332 is selected, a friend or acquaintance to transmit the detailed information of the emergency setting hospital can be registered in advance.

Detailed information of the emergency setting hospital transmitted from the mobile terminal 100 on the mobile terminal 400 carried by the friend or acquaintance can be displayed.

Detailed information may include emergency referral information, hospital location, hospital contact information, and patient inpatient ward.

14 is a view for explaining a method of transmitting and receiving information using visible light wireless communication for each sector in a large shop.

14, a large-sized store is divided into four sectors (A, B, C, and D), and the sectors A, B, C, -Fi transceiver may be provided.

In this case, product information displayed in each sector may be provided through at least one Li-Fi transceiver included in each of the sectors A, B, C, and D.

For example, when confectioneries are displayed in the A sector and various drinks are displayed in the B sector, various kinds of clothes can be displayed in the C sector, and various sports goods can be displayed in the D sector.

For example, when the user is located in the sector A, the confectionery information displayed on the sector A can be transmitted to the mobile terminal owned by the user.

If the user moves from sector A to sector D, sporting goods information displayed on the sector D can be transmitted to the mobile terminal owned by the user.

In this way, when a store is large or many merchandise items are displayed in a store, the store is divided into a plurality of sectors, and each sector is provided with at least one Li-Fi transceiver, so that even if there are large- Product information can be easily provided.

Although not shown, an augmented reality device can be used. When a mobile terminal is connected to an augmented reality device, for example, a room, a room, a restaurant or a kiosk position of each floor in a hospital, which is a high-rise building, is implemented as an augmented reality, and the information can be provided to the user in a more stereoscopic manner.

On the other hand, when a message regarding receipt of each object information is simultaneously received from a plurality of objects, only a specific object among these various objects can be selected.

As shown in FIG. 15, when messages (343, 345, and 347) related to receipt of each object information are simultaneously received from various objects, messages (343, 345, and 347 May be displayed in the pop-up window 341. [

For example, a reception message 343 for the object A, a reception message 345 for the object B, a reception message 347 for the object C, and the like may be displayed.

If one of them is selected, for example, a reception acknowledgment message 343 for the object A is selected, the object information corresponding to the reception acknowledgment message 343 for the selected object A is received and displayed on the touch screen 151, The object information corresponding to the messages (345, 347) for the objects B and C can be maintained in the waiting state.

If the reception object message 345 for the object B is selected after the display of the detailed information of the object A is canceled, the object information corresponding to the reception of the selected object B is received and displayed on the touch screen 151 And object information corresponding to the unselected messages, that is, the reception acknowledgment messages 343 and 347 for the object A and the object C, can be maintained in a standby state.

As another example, when a message regarding reception of each object information is simultaneously received from a plurality of objects, object information of the object having the largest brightness of light emitted from the Li-Fi transceiver provided in each object may be displayed preferentially have.

For example, a user's mobile terminal is positioned between adjacent objects A and B, and a message regarding whether to receive each object information from both the neighboring objects A and B can be received. When the brightness of the light emitted from the Li-Fi transceiver provided in the object A is larger than the brightness of the light emitted from the Li-Fi transceiver provided in the object B, the object information of the object A precedes the object information of the object B, 151). ≪ / RTI >

The following preconditions must be met for this operation.

First, the brightness of the light emitted from the Li-Fi transceiver included in each object is the same.

Secondly, the brightness of the light emitted from the Li-Fi transceiver of each object detected by the mobile terminal changes according to the distance between the object and the mobile terminal requested by the user.

Accordingly, the closer the user's mobile terminal is to the object, the brighter the light emitted from the Li-Fi transceiver included in the object detected by the mobile terminal can be brightened.

Therefore, even if the user's mobile terminal is located in a region where the light emitted from each of the adjacent objects A and B overlap each other, the object information of the object located closer to the user's mobile terminal among the object A and the object B takes precedence Lt; / RTI >

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet).
