Furthermore, unless specifically defined otherwise in this invention, the technical terms used in this invention should be interpreted in the sense generally understood by those skilled in the art to which this invention pertains, and should not be interpreted in an overly broad or overly narrow sense.

[0023] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0024] A translation service providing system according to embodiments of the present invention may be implemented by at least one computer device, and a translation service providing method according to embodiments of the present invention may be performed through at least one computer device included in the translation service providing system. In this case, a computer program according to one embodiment of the present invention may be installed and run on the computer device, and the computer device may perform a translation service providing method according to embodiments of the present invention under the control of the run computer program. The above-described computer program may be stored on a computer-readable recording medium to be combined with the computer device to execute the translation service providing method on the computer.

[0026] FIG. 1 is a block diagram illustrating the configuration of a translation service providing system according to one embodiment of the present invention.

[0027] As shown in FIG. 1, a translation service providing system according to one embodiment includes an LCD device (10) and a translation server (20).

[0028] A translation service providing system according to one embodiment receives voice input from people facing each other through a microphone, converts the input voice signal into digital voice data, and then converts it into text data. Then, through a recognition and translation process of the converted text data, the provided translation data is displayed in a visible form on the transparent LCD window of the LCD device (10).

[0029] The transparent LCD is a first enclosure such as a transparent Lexan-like enclosure, Advanced Link Photonics (ALP), Inc. A first retardation film having a half-wavelength mirror having a mirror reluctance of 15 to 60 percent, such as a retardation film manufactured by (California, Irvine) Inc.; a first diffusion surface or diffraction surface or element having a surface haze between 0 and 30 percent; a first optical grade plastic having a cold cathode fluorescent lamp (CCFL) or light-emitting diode (LED) surrounding the optical grade plastic; a second diffusion surface having a surface haze of 0 to 60 percent; a first translucent film such as a translucent film manufactured by ALP, Inc.; an LCD panel; a second translucent film such as a translucent film manufactured by ALP, Inc.; a third diffusion surface having a surface haze of 0 to 60 percent; a second optical grade plastic having a cold cathode fluorescent lamp (CCFL) or light-emitting diode (LED) surrounding the optical grade plastic; The configuration may include a fourth diffusion surface or diffraction surface or a device having a surface haze between 0 and 30 percent, a second polarizer delay film having a half-wavelength mirror having a mirror reluctance of 15 to 60 percent such as a polarizer delay film manufactured by ALP, Inc., and a second enclosure such as a transparent Lexan-like enclosure. The above configurations are merely examples and can be replaced with other configurations.

[0030] Additionally, a speaker is added to convert the translation data into voice data and output it, so that the conversation content translated into the language used by the listener is displayed through the transparent LCD of the LCD device (10) placed between two people facing each other regarding what the other person said in a different language. The speaker may be configured to output TTS (Text to Speech) information as a voice desired by the user.

[0031] FIGS. 2 and FIGS. 3 are illustrative diagrams for explaining the operation of an LCD device according to one embodiment.

[0032] In one embodiment, as shown in FIG. 2, the LCD device (10) is implemented as a transparent LCD (1110).

[0033] The transparent LCD (1110) has a structure in which a liquid crystal display is applied between two glass panels made of a special glass material with transparent properties. The liquid crystal display can display images by utilizing the property that a liquid changes optically through electricity. The display panel operates in the same way as a conventional LCD, and the pixels that make up the image have transparent properties. That is, an electrical signal is transmitted through the liquid crystal display panel, and the state of the pixels changes due to the optical properties of the liquid crystal crystals. Through this, images or text are displayed, and the contents appear on the screen through backlight illumination.

[0034] By placing an LCD device (10) implemented as a transparent LCD (1110) between conversationalists (a, b) who use different languages, and providing the language spoken by the person facing them in the language used by the listener, smooth communication between conversationalists who use different languages ​​can be made possible.

[0035] For example, if user a says "hello" using their own language, the text "Hello" is displayed on the transparent LCD (1110) in the direction viewed by user b, the listener. Conversely, if user b says "Hello" using their own language, the text "hello" is displayed on the transparent LCD (1110) in the direction viewed by user a, the listener.

[0036] This can be applied in various situations and environments, such as when foreigners use government offices, communicate with buyers during business meetings, interact with foreigners during immigration screenings at airports, visits to duty-free shops or places frequented by foreigners, use of public transportation like taxis or buses, or during medical appointments and tests.

[0037] In one embodiment, the LCD device (10) is implemented to be able to rotate 360° with respect to an axis (1120) fixed at the bottom center.

[0038] Accordingly, it can be conveniently applied not only to two-way conversations facing each other at a 180° angle but also to multi-party conversations. Additionally, when on a phone call with another party, the system is implemented so that the audio is displayed on the phone side, while the text is displayed on the LCD screen for the person looking at the screen. Regardless of the input language, it is implemented to translate and output the content in the listener's language from the direction the listener is facing.

[0039] Additionally, as shown in FIG. 3, a user terminal (40) can be mounted on one side of the LCD device (10). Then, the LCD device (10) can predict the language used by the listener based on the identification information of the mounted user terminal (40). The mounting position of the user terminal (40) may be implemented so that only two user terminals (40) can be mounted at 180° intervals, or three at 120° intervals, or four at 90° intervals, and so on, allowing for participation with a larger number of user terminals.

[0040] Specifically, the LCD device (10) includes a microphone (110), a translation processing unit (120), a screen display unit (130), a voice conversion unit (140), a speaker (150), and a terminal linkage unit (160).

[0041] The LCD device (10) may be implemented to perform network communication such as Wi-Fi by having a communication interface within itself. However, it is not limited thereto and may be implemented to perform network communication in conjunction with a user terminal.

[0042] The microphone (110) receives voice data from the speakers. In one embodiment, it is preferable that the microphone (110) be positioned to face both sides of the transparent LCD glass panel of the LCD device (10).

[0043] The translation processing unit (120) transmits voice data input through the microphone (110) to the translation server (20) and receives the translated text of the voice data input through the microphone (110) from the translation server (20).

[0044] In one embodiment, the translation processing unit (120) further provides voice data, identification information for identifying the LCD device (10), and language information of the listener to translate the voice data.

[0045] In one embodiment, the translation processing unit (120) may be implemented to translate into at least two different languages.

[0046] The screen display unit (130) displays the translation text received by the translation processing unit (120) in a visible form. At this time, the screen display unit (130) of the LCD device can be implemented as one of 4 inches, 12 inches, 20 inches, or 21 inches, but is not limited thereto and can be implemented in various sizes.

[0047] In one embodiment, the screen display unit (130) may be implemented to have a touchscreen function. It may be implemented to perform functions such as screen adjustment, brightness adjustment, or translation language setting using a touch method.

[0048] The screen display unit (130) can display translation data translated into two different languages ​​simultaneously on a single screen when the translation processing unit (120) processes translation into two or more different languages ​​according to the settings. At this time, it is also possible for the translation data translated into two or more different languages ​​to be displayed with a time difference. When displayed with a time difference, the time difference setting information and the setting information regarding whether to display with a time difference or simultaneously on one screen are implemented to be input using the touchscreen function of the screen display unit (130).

[0049] Accordingly, it has the effect of smoothly translating not only conversations between speakers using two different languages ​​but also conversations between speakers using three or more different languages ​​through the transparent LCD device (10).

[0050] In one aspect, the LCD device (10) detects the direction of the microphone voice input to recognize the direction of the speaker, and the screen display unit (130) displays the translated text in a visible form through a glass panel on the side opposite to the direction of the speaker.

[0051] For example, when voice input is input via a microphone on the first side, the LCD device (10) displays translation data on the opposite side of the first side.

[0052] Additionally, the LCD device (10) according to one aspect may be further equipped with a camera to infer the language used by the speakers through facial recognition of the speaker captured by the camera.

[0053] For example, nationality can be inferred using deep learning technology based on skin color or hair color information. However, to provide convenience even if the accuracy is somewhat lower, at least two nationalities can be inferred to provide a language selection list, and the system can be implemented to allow the listener to select their language from the provided list. In other words, convenience can be provided by offering a language selection list based on facial recognition that includes languages ​​likely to be spoken by the listener.

[0054] The network (30) may include any one or more networks such as a PAN (personal area network), LAN (local area network), CAN (campus area network), MAN (metropolitan area network), WAN (wide area network), BBN (broadband network), and the Internet. Additionally, the network (30) may include any one or more network topologies such as a bus network, a star network, a ring network, a mesh network, a star-bus network, a tree or hierarchical network, but is not limited thereto.

[0055] The terminal linkage unit (160) links with the translation service dedicated app of the user terminal (40) on which the translation service dedicated app is installed.

[0056] The user terminal (40) may be a fixed terminal or a mobile terminal implemented as a computer device. The user terminal may be implemented as a computer capable of connecting to a remote server or terminal via a network. Here, the computer may include, for example, a notebook, desktop, laptop, etc. equipped with a web browser. Additionally, the user terminal (40) may be implemented as a terminal capable of connecting to a remote server or terminal via a network. The user terminal (40) may include all kinds of handheld-based wireless communication devices, such as a PCS (Personal Communication System), GSM (Global System for Mobile communications), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet) terminal, smartphone, smartpad, tablet PC, etc.

[0057] In one embodiment, the user terminal (40) is interpreted to include a terminal device possessed by a user who wishes to use a translation service using a transparent LCD device (10).

[0058] The translation processing unit (120) can identify the language used by the listener by linking with a dedicated app for translation services.

[0059] In one embodiment, the translation processing unit (120) can infer the language used by the listener by comprehensively considering the user's device settings, region information, previous language settings, user profile information, language selection history, etc. in conjunction with the user terminal (40).

[0060] In another embodiment, the LCD device (10) itself may not be provided with a communication interface for performing network communication, and data communication with the translation server (20) may be enabled through a user terminal (40).

[0061] At this time, the LCD device (10) may be implemented to include a short-range wireless communication module such as Bluetooth, NFC (Near Field Communication), or Zigbee for interoperability with a user terminal (40).

[0062] In a further aspect of the present invention, the voice conversion unit (140) converts the translation text received from the translation processing unit (120) into a translated voice using voice synthesis technology.

[0063] And the speaker (150) outputs the converted translation voice from the voice conversion unit (140) in the form of an audible sound. Accordingly, the translation data can be displayed in a visible form on the glass panel of the LCD device (10) and the translated translation data can be output in the form of voice at the same time, or it can be implemented to output only in the form of voice without outputting in a visible form.

[0064] The translation server (20) can be implemented in the form of a web server, a database server, a proxy server, etc. Additionally, the translation server (20) may be equipped with one or more of a network load balancing mechanism or various software that enables the translation server (20) to operate on the Internet or another network, thereby enabling it to be implemented as a computerized system.

[0065] Additionally, the network may be an HTTP network, a private line, an intranet, or any other network. Furthermore, the connection between the LCD device (10) and the user terminal (40) may be connected via a secure network to prevent data from being attacked by any hacker or other third party. Additionally, the translation server (20) may include a plurality of database servers, and these database servers may be implemented in such a way that they are connected separately from the translation server via any type of network connection, including a distributed database server architecture.

[0066] In one embodiment, the translation server (20) includes a communication interface (210), a memory (220), an input / output interface (230), and a processor (240).

[0067] The communication interface (210) can provide a function for communicating with the LCD device (10) and the user terminal (40) through the network (30). For example, requests, commands, data, files, etc. generated by the processor (240) of the translation server (20) according to program code stored in a recording device such as memory (220) can be transmitted to other devices through the network (30) under the control of the communication interface (210).

[0068] Conversely, signals, commands, data, files, etc. from other devices may be received by the translation server (20) via the communication interface (210) of the translation server (20) through the network (20). Signals, commands, data, etc. received through the communication interface (210) may be transmitted to a processor (240) or memory (220), and files, etc. may be stored in a storage medium (the permanent storage device described above) that the translation server (20) may further include.

[0069] Memory (220) is a computer-readable recording medium and may include a non-perishable mass storage device such as RAM (random access memory), ROM (read only memory), and a disk drive. Here, a non-perishable mass storage device such as a ROM and a disk drive may be included in the translation server (20) as a separate permanent storage device distinct from memory (220).

[0070] Additionally, an operating system and at least one program code may be stored in the memory (220). These software components may be loaded into the memory (220) from a computer-readable recording medium separate from the memory (220). This separate computer-readable recording medium may include a computer-readable recording medium such as a floppy drive, disk, tape, DVD / CD-ROM drive, or memory card.

[0071] In another embodiment, software components may be loaded into memory (220) via a communication interface (210) rather than a computer-readable recording medium. For example, software components may be loaded into the memory (220) of the translation server (20) based on a computer program installed by files received through the network (30).

[0072] The input / output interface (230) may be a means for interfacing with an input / output device. For example, the input device may include a device such as a microphone, keyboard, or mouse, and the output device may include a device such as a display or speaker. As another example, the input / output interface (230) may be a means for interfacing with a device in which the functions for input and output are integrated into one, such as a touchscreen. The input / output device may be composed of the translation server (20) and a single device.

[0073] The processor (240) may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations. Instructions may be provided to the processor (240) via memory (220) or a communication interface (210). For example, the processor (240) may be configured to execute instructions received according to program code stored in a recording device such as memory (220).

[0074] The processor (240) includes a request receiving unit (242), a data conversion unit (244), a translation unit (246), and a translation data providing unit (248).

[0075] The request receiving unit (242) receives voice data and a translation request from the LCD device (10).

[0076] It is implemented to include information on which language the translation request should be translated into.

[0077] And the data conversion unit (244) recognizes the voice data received by the request receiving unit (242) and converts it into text.

[0078] The data conversion unit (244) performs speech recognition technology that analyzes a voice signal and converts the voice into text.

[0079] The data conversion unit (244) converts voice data received by the request receiving unit (242) into digital signals through a signal processing process. That is, it samples, quantizes, and converts voice signals into digital signals to form that can be processed by a computer.

[0080] Furthermore, it includes information on various languages ​​and phonetic characteristics and constructs an acoustic model capable of recognizing speech features. It also includes sentence structure, grammar, and vocabulary, and constructs a language model designed to provide context-appropriate results when converted to text.

[0081] Then, by utilizing the constructed acoustic and language models, speech data is analyzed to construct sentences from recognized words based on the vocabulary and grammatical rules of the corresponding language. Accordingly, the result of converting the speech data into text can be derived.

[0082] The translation unit (246) translates the text data converted by the data conversion unit (244) into the language used by the listener.

[0083] In one embodiment, the translation unit (246) may be implemented to perform machine translation (MT). The translation unit (246) may be implemented to perform translation using a rule-based machine translation (RBMT) method, which performs translation based on grammatical rules and vocabulary information. In this case, the translation rules are manually written by people when performing translation tasks and include language dictionaries and grammatical rules. The input sentence may be implemented to be parsed and translated according to these rules to generate an output sentence. The RBMT method has strengths in terms of accuracy and consistency.

[0084] Additionally, the translation unit (246) may be implemented to perform translation using a statistical machine translation (SMT) method that performs translation based on a large amount of language data. The translation unit (246) generates a statistical model from training data and uses this model to translate an input sentence. The SMT considers sentence-level statistical similarity and context, and generates a probabilistic translation result of the input sentence.

[0085] Additionally, the translation unit (246) can perform translation by performing Neural Machine Translation (NMT) based on deep learning and artificial neural networks. NMT is a method of translating sentences by utilizing an artificial neural network model, and performs translation by learning the complex relationship between the input sentence and the target sentence. Although NMT requires a large amount of training data and computational resources, it can provide more natural translation results.

[0086] The translation data provider (248) provides the translated text from the translation unit (246) to the LCD device (10) through the communication interface (210). The translation unit (246) can receive a request for voice data translation from at least two LCD devices (10). When receiving a translation request, it also receives identification information of the LCD device (10) and, after translation, transmits the translated text to the corresponding LCD device (10) in correspondence with the identification information of the LCD device (10) received at the time of the translation request.

[0087] FIG. 4 is a flowchart illustrating a method for providing a translation service according to an embodiment of the present invention.

[0088] In one embodiment, a translation service providing method operated in a translation service providing system including an LCD device and a translation server is such that when voice data is input through a microphone to the LCD device (10) (S400), the voice data input through the microphone is transmitted to the translation server (S410).

[0089] The LCD device (10) further provides voice data, identification information for identifying the LCD device (10), and information on the language used by the listener to translate the voice data to the translation server (20). In one embodiment, the LCD device (10) may be implemented to translate into at least two different languages.

[0090] Subsequently, the translation server (20) receives voice data and a translation request from the LCD device (10), and recognizes the received voice data and converts it into text (S420). In one embodiment, the data conversion step performs speech recognition technology that analyzes the voice signal and converts the voice into text.

[0091] The data conversion step converts voice data received from the LCD device (10) into digital signals through a signal processing process. That is, the voice signal is sampled, quantized, and converted into a digital signal to be converted into a form that can be processed by a computer.

[0092] Afterwards, the translation server (20) translates the converted text data into the language used by the listener (S430).

[0093] In one embodiment, the translation step may perform translation by executing Neural Machine Translation (NMT) based on deep learning and artificial neural networks. NMT is a method of translating sentences by utilizing an artificial neural network model, and performs translation by learning the complex relationship between an input sentence and a target sentence. Although NMT requires a large amount of training data and computational resources, it can provide more natural translation results. However, it is not limited thereto.

[0094] And the translation server provides the translated text to the LCD device during the translation stage (S440).

[0095] Afterwards, the LCD device (10) receives the translated text of voice data input via microphone from the translation server (20) (S450).

[0096] Then, the LCD device (10) displays the translation text received from the translation server (20) in a visible form (S460).

[0097] In a further aspect of the present invention, an LCD device (10) converts a received translation text into a translation voice using speech synthesis technology and outputs the converted translation voice in the form of an audible sound through a speaker (S470).

[0098] In one embodiment, the LCD device (10) detects the direction of the microphone voice input to recognize the direction of the speaker, and the step of displaying the translation text in a visible form through a glass panel on the side opposite to the direction of the speaker.

[0099] In a further aspect of the present invention, the LCD device (10) is linked with a translation service dedicated app of a user terminal on which a translation service dedicated app is installed (S480).

[0100] And the translation step identifies the language being used by linking with a dedicated translation service app.

[0101] In one embodiment, the translation step may infer the listener's language by linking with a dedicated translation service app on the user terminal and comprehensively considering the user's device settings, region information, previous language settings, user profile information, language selection history, etc. A request for translation can be made in the inferred listener's language.

[0103] The above-described method may be implemented as an application or in the form of program instructions that can be executed through various computer components and recorded on a computer-readable recording medium. The computer-readable recording medium may include program instructions, data files, data structures, etc., either individually or in combination.

[0104] The program instructions recorded on the above-mentioned computer-readable recording medium are those specifically designed and configured for the present invention, but may also be those known and available to those skilled in the art of computer software.

[0105] Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tapes; optical recording media such as CD-ROMs and DVDs; magneto-optical media such as floptical disks; and hardware devices specifically configured to store and execute program instructions such as ROM, RAM, and flash memory.

[0106] Examples of program instructions include machine code, such as that generated by a compiler, as well as high-level language code that can be executed by a computer using an interpreter, etc. The hardware device may be configured to operate as one or more software modules to perform processing according to the present invention, and vice versa.

[0107] Although the invention has been described above with reference to embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims.
