Furthermore, parts common to the following embodiments are given the same reference numerals, and explanations thereof may be omitted.

[0009] [Embodiment] [Configuration] Fig. 1 is a perspective view schematically illustrating an example of the appearance of a translation device 10 according to an embodiment. Fig. 2 is a block diagram illustrating an example of the hardware configuration of the translation device 10 according to an embodiment.

[0010] As shown in Fig. 1, the translation device 10 has a speaker 18 arranged above a touch panel 12, which is a display screen, and a microphone 19 arranged below the speaker 18. The positions of the speaker 18 and microphone 19 can be changed as appropriate. The translation device 10 can also be implemented as a mobile terminal such as a smartphone or tablet by installing an app (application) or program that provides the functions of the translation device 10, which will be described later. The translation device 10 can communicate with a server 20 via a network 30, such as the Internet, as shown in Fig. 2, for example.

[0011] 2, the translation device 10 includes, as its hardware configuration, a control unit 11, a touch panel 12, a communication circuit 14, a processor 15, a memory 16, a storage device 17, a speaker 18, and a microphone 19. The control unit 11, the touch panel 12, the communication circuit 14, the processor 15, the memory 16, and the storage device 17 are connected via a bus 13.

[0012] The touch panel 12 is a display device of the translation device 10 and an input device that serves as a user interface for accepting user operations. The display content of the touch panel 12 is controlled by the control unit 11 via the bus 13. The operations accepted by the touch panel 12 are acquired by the control unit 11 via the bus 13. The communication circuit 14 is a communication interface that can be connected to the network 30 by a predetermined wireless communication method. The radio wave status of the communication circuit 14 is acquired by the control unit 11 via the bus 13.

[0013] Processor 15 is a central processing unit that executes instructions included in programs and applications stored in memory 16. Memory 16 is a dynamic random access memory (DRAM) or the like. At least one of a program for realizing the functions of translation device 10 and an application that utilizes the functional configuration of translation device 10 is deployed in memory 16.

[0014] The storage device 17 is, for example, a hard disk drive (HDD) or a solid state drive (SSD). The storage device 17 stores settings for the translation device 10, voice data acquired by the translation device 10, text (script), translated text, etc. In the present embodiment, a text conversion engine that converts voice to text, a translation engine that translates text from one language into another language, a voice conversion engine that converts text to voice, etc., or AI that realizes these engines, are operated on the server 20 and used by the translation device 10 via the network 30. However, at least a part of these engines or AI may be stored in the storage device 17.

[0015] The microphone 19 is a device that collects voice for voice input to the translation device 10. The speaker 18 is an output device that allows the translation device 10 to output voice.

[0016] The control unit 11 is realized using a processor 15, a memory 16, and the like. That is, the control unit 11 realizes various functions by the processor 15 executing predetermined programs stored in the memory 16. The control unit 11 can also acquire text (script) in a language input by voice, translation results, and the like, using AI stored in the storage device 17 or the server 20. The functions of the control unit 11 will be described below with reference to the drawings.

[0017] [Control Unit 11] FIG. 3 is a schematic screen diagram illustrating a screen displayed on the translation device 10 according to the embodiment. In the example of FIG. 3, the screen of the touch panel 12 is divided into two, upper and lower. FIG. 3 illustrates an example in which a user of the translation device 10 is located on the lower side of FIG. 3 and views the touch panel 12 from the lower side of FIG. 3, and a conversation partner of the user is located on the upper side of FIG. 3 and views the touch panel 12 from the upper side of FIG. 3. (a) of FIG. 3 illustrates that the direction for viewing icons and the like arranged on one side of the divided screen and the direction for viewing icons and the like arranged on the other side are rotated 180° on the touch panel display screen. (b) of FIG. 3 illustrates that the direction for viewing text included in a character display area arranged on one side of the divided screen and the direction for viewing text included in a character display area arranged on the other side of the divided screen are rotated 180° on the touch panel display screen. FIG. 4 is a schematic screen diagram illustrating a screen displayed when selecting a language on the divided screen. 5A and 5B are schematic diagrams illustrating how the background color changes depending on the radio wave conditions on a screen divided into two parts. Fig. 5A shows a case where the radio wave conditions are good, and Fig. 5B shows a case where the radio wave conditions are not good.

[0018] The control unit 11 (FIG. 2) divides the screen of the touch panel display into two or more sections, and displays on each of the two or more divided sections an area for selecting the language to be translated and an icon for activating the microphone 19 for a predetermined time to input voice information. When the icon on the first screen of the two or more divided sections is touched, the control unit 11 activates the microphone 19 for a predetermined time. Here, the predetermined time is, for example, 10 to 30 seconds, but can be changed as appropriate.

[0019] 3A, the control unit 11 divides the screen of the touch panel 12 into two screens, a first screen 121 and a second screen 122. The control unit 11 arranges and displays, on the first screen 121, a box area 131 for selecting a language used by the user of the translation device 10, an icon 132 for the user to input voice using the microphone 19, and an icon 133 for returning to the home screen. The control unit 11 also arranges and displays, on the second screen 122, a box area 134 for selecting a language used by a party who speaks a language different from the language used by the user, and an icon 135 for the party to input voice using the microphone 19.

[0020] In this embodiment, the control unit 11 displays the first screen 121 and the second screen 122 so that the direction for viewing the icon 132 on the first screen 121 and the direction for viewing the icon 135 on the second screen 122 differ by 180° on the touch panel 12. For example, as shown in (a) of Fig. 3, the control unit 11 rotates at least the icon 135 by 180° as the display on the second screen 122.

[0021] Furthermore, in the present embodiment, when a voice input in a first language selected on the first screen 121 is performed, the control unit 11 displays a first character display area 125 containing text in the first language, which is the content (words) of the voice input in the first language, on the first screen 121. Then, the control unit 11 translates the voice input content in the first language into a second language and displays a second character display area 126 containing text in the second language, which is the translated content in the second language, on the second screen 122. For example, as shown in (b) of FIG. 3 , the control unit 11 can display the first screen 121 and the second screen 122 so that the direction for viewing the text in the first language on the first screen 121 and the direction for viewing the text in the second language on the second screen 122 are 180° apart on the screen of the touch panel 12.

[0022] After the control unit 11 displays the second character display area 126 on the second screen 122, it may convert the text in the second language into voice and output the voice from the speaker 18. In this case, as shown in (b) of FIG. 3, the control unit 11 may display an icon 136 for converting the text in the second language into voice and outputting the voice from the speaker 18 in the area of the second character display area 126. The user or the counterpart of the translation device 10 can repeatedly listen to the voice obtained by converting the text in the second language into voice (i.e., the voice of the translation result) by touching the icon 136 displayed on the screen of the touch panel 12.

[0023] In (b) of FIG. 3, it is shown that Japanese is displayed in the box area 131 and the first language is Japanese used by the user, and English is displayed in the box area 134 and the second language is English used by the counterpart.

[0024] When the user or the counterpart selects a language, the control unit 11 displays an interface screen for language selection, for example, as shown in FIG. 4. In the example shown in FIG. 4, an interface screen 127 for the user to select a language is displayed. On the interface screen 127, selectable languages (candidate languages) are listed at a size that is not too small and without unnecessary strokes at a position where it is easy to select, such as near the center of the touch panel 12, so that they can be selected. The selectable languages are indicated by display in Japanese and display in the candidate language so that the user and the counterpart can understand. For example, English is indicated by display in Japanese as "English" and display in English as "English". The top 3 languages with high usage frequency or easy to use for each user using the translation device 10 are registered as candidate languages, and they are displayed from the top 3, and those with low usage frequency can be selected by scrolling the interface screen. Note that the interface screen for the counterpart to select a language is the same except that it is displayed rotated 180° with respect to the interface screen 127 for the user to select a language, so the description is omitted.

[0025] The control unit 11 also displays the status of the radio waves used by the communication circuit 14 ( FIG. 2 ) on one of the two or more divided screens. In this embodiment, the translation device 10 performs translation, etc., using, for example, AI running on the server 20. For this reason, as shown in FIG. 3B , the control unit 11 displays text 123 indicating the radio wave status on the second screen 122 without rotating it 180° relative to the display on the first screen 121. In the example shown in FIG. 3B , an icon 124 indicating radio wave strength displays information indicating that four antennas are standing, indicating that 4G communication is possible, and the text 123 displays "good signal." The control unit 11 determines whether the radio wave status is good not from the information displayed on the icon 124 but from the communication status obtained by measuring the time until an actual communication response at the time the screen of the touch panel 12 is displayed (before translation is performed using the translation device 10),

[0026] Here, control unit 11 may change the display of an area of ​​the screen of touch panel 12 excluding at least the icon area, depending on the radio wave conditions. The area excluding at least the icon area may be a background area of ​​the screen of touch panel 12, or may be an area of ​​the entire screen of touch panel 12 excluding the icon area. The entire screen area of ​​touch panel 12 may be a so-called wallpaper.

[0027] In this embodiment, when the radio wave conditions are good, the control unit 11 may display characters 123 indicating good radio wave conditions, as shown in (a) of FIG. 5 . On the other hand, when the radio wave conditions are poor, the control unit 11 may display characters 123A indicating poor radio wave conditions, as shown in (b) of FIG. 5 , and may change the color of the background region of the screen of the touch panel 12. Note that the hatching in the background region shown in (b) of FIG. 5 represents a color such as red. As shown in (b) of FIG. 5 , the background region of the screen of the touch panel 12 is the region of the screen of the touch panel 12 excluding the box region 131, the box region 134, the region of the icon 132, the region of the icon 133, the region of the icon 135, the first character display region 125, and the second character display region 126.

[0028] [Operation] Next, the operation of the translation device 10 configured as above will be described.

[0029] 6 is a flowchart for explaining an example of the operation of the translation device 10 according to the embodiment. In the following, an example will be described in which a user of the translation device 10 who speaks a first language makes the translation device 10 translate for a party who speaks a second language, but the same applies to a case in which the party makes the translation device 10 translate for the user.

[0030] First, the translation device 10 checks whether or not an icon for speech input has been touched (S11).

[0031] When the translation device 10 confirms that the icon for speech input has been touched (Yes in S11), it enables the microphone 19 for a predetermined time. In this embodiment, the translation device 10 confirms that the icon 132 for speech input on the first screen 121 has been touched. Note that the predetermined time is 10 to 30 seconds, but is not limited to this. It can be changed as appropriate as long as it is a time that is appropriate for the user or the other party to gather their thoughts and speak (speech input).

[0032] Next, the translation device 10 acquires speech input to the microphone 19 (S12). In this embodiment, the translation device 10 acquires speech in the first language that is input to the microphone 19.

[0033] Next, translation device 10 displays text in the language input by voice in step S12 (S13). In this embodiment, translation device 10 converts the content (words) of the acquired voice in the first language into text using, for example, AI running on server 20, and displays the text in the first language in first character display area 125 of first screen 121.

[0034] Next, the translation device 10 displays the translation result of the language inputted by speech in step S12 (S14). In this embodiment, the translation device 10 uses, for example, AI running on the server 20 to translate the acquired speech content (words) in the first language into the second language, and displays the text in the second language, which is the content in the second language, in the second character display area 126 of the second screen 122. Note that the translation device 10 may obtain the text in the second language by translating the text in the first language.

[0035] Next, the translation device 10 outputs the translation result through the microphone 19 (S15). In this embodiment, the translation device 10 outputs the speech obtained by converting the text in the second language into speech.

[0036] Next, the translation device 10 checks whether an icon for outputting sound from the microphone 19 has been touched (S16), and if it checks that icon 136 on the second screen 122 for outputting sound has been touched (Yes in S16), it outputs the translation result from the microphone 19 (S17).

[0037] [Effect] In conventional translation devices, the text in the first language input by the user through speech and the translated text are displayed side by side on a single screen so that only the user can see them.

[0038] In contrast, in this embodiment, the screen of the touch panel 12 of the translation device 10 is split into two screens, one of which displays the text of the first language content input by voice by the user, and the other screen displays the text of the second language content translated from the first language content into the second language.

[0039] This allows a user and a person to communicate face-to-face or side-by-side (translation dialogue) using one translation device 10, making it possible for the user to easily communicate with a person who speaks a different language.

[0040] Furthermore, the translation device 10 rotates the display of one screen and the other screen of the two split screens by 180 degrees. Examples of the 180-degree rotated display include icons and text (scripts) for voice input. This allows for easy communication between a user and a person in a face-to-face interaction (translation dialogue) because the display is tailored to the user and the person.

[0041] Furthermore, when the translation device 10 performs translation using, for example, AI running on the server 20, the translation device 10 may change the display of the background area of ​​the two split screens depending on the radio wave conditions. This allows the user and the other party to use the translation device 10 to have a conversation (translation dialogue) when the communication status with the server 20 is good, thereby enabling good communication.

[0042] Furthermore, the user or the other party only needs to touch an icon for voice input on the translation device 10 and then input the voice within a predetermined time. In this way, there is no need to keep touching the icon, and the user or the other party can organize their thoughts before inputting the voice. In other words, the ease of use of the translation device 10 allows the user or the other party to concentrate on communicating.

[0043] Other Embodiments The translation device 10 according to the embodiments has been described above. However, the translation device 10 according to these embodiments is merely an example, and the specific configuration, operation, etc. can be adjusted as appropriate.

[0044] Fig. 7 is a schematic screen diagram for explaining a screen that is not rotated 180° and is split horizontally into two. Fig. 8 is a schematic screen diagram for explaining that the colors of the character display areas on the split screen are different.

[0045] In the above embodiment, the control unit 11 divides the screen of the touch panel 12 into two vertically (top and bottom in the figure) for display, as shown in (a) of Fig. 3, but this is not limited to this. For example, as shown in Fig. 7, the control unit 11 may divide the screen of the touch panel 12 into two horizontally (left and right in the figure) for display. In this case, the control unit 11 may divide the screen of the touch panel 12 into two parallel screens, a first screen 121B and a second screen 122B. Note that the arrangement of the first screen 121B and the second screen 122B may be reversed.

[0046] In the above embodiment, the control unit 11 changes the color of the background depending on the radio wave conditions, as shown in Fig. 5(a) and (b), but this is not limiting. For example, instead of changing the color of the entire background depending on the radio wave conditions, the color of only part of the background may be changed.

[0047] Furthermore, the control unit 11 can change the color of the screen area of ​​the touch panel 12, excluding at least the icon area, depending on the radio wave conditions. Such areas include areas other than the background. For example, as shown in FIG. 8 , the control unit 11 may display the first character display area 125C of the first screen 121 and the second character display area 126C of the second screen 122 in different colors depending on the radio wave conditions. Note that the hatching of the first character display area 125C and the second character display area 126C shown in FIG. 8 indicates that they are different colors from the first character display area 125 and the second character display area 126.

[0048] Furthermore, the control unit 11 may change the display of the area of ​​the screen of the touch panel 12, excluding at least the icon area, depending on the radio wave conditions, by means other than changing the color. Possible means for this purpose include changing the color ratio, the design, or the pattern.

[0049] In the above embodiment, the screen of the touch panel 12 of one translation device 10 is divided into two, the first screen 121 and the second screen 122, and a case has been described in which a single translation device 10 is used to perform translation (face-to-face translation) between a user and a person speaking a different language. However, this is not limited to this. The first screen 121 and the second screen 122 may be displayed on the translation device 10 carried by the user and the person speaking a different language, respectively, to carry out a translation dialogue. The translation device 10 used by the person speaking a different language may be a wristwatch-type terminal or other wearable terminal, or may be a mobile terminal such as a smartphone or tablet.

[0050] Fig. 9 is an explanatory diagram for explaining a translation dialogue using a translation device 10D that is a smartphone and a translation device 10E that is a wristwatch-type terminal. Fig. 10 is an explanatory diagram for explaining a translation dialogue using two translation devices 10D and 10F that are smartphones.

[0051] The user's translation device 10 may be a translation device 10D that is a smartphone installed with an app that provides the functions of the translation device 10, as shown in FIGS. 9 and 10 . Similarly, the other party's translation device 10 may be a translation device 10E that is a wristwatch-type terminal installed with an app that provides the functions of the translation device 10, or a translation device 10F that is a smartphone, as shown in FIGS. 9 and 10 . In such cases, the first screen 121D is displayed on the touch panel 12 of the translation device 10D used by the user. Also, the second screen 122E or 122F is displayed on the touch panel 12 of the translation device 10E or 10F used by the other party. In this way, instead of dividing the screen into the first screen and the second screen and using one translation device for translation dialogue, two translation devices may be used, with the first screen displayed on one screen and the second screen displayed on the other screen.

[0052] Such cooperation between the two translation devices may be achieved using a QR code (registered trademark) or the like.

[0053] Furthermore, the app, program, etc. according to any of the embodiments may be activated in response to voice recognition using a microphone mounted on a mobile device such as a smartphone or tablet, or a microphone mounted on a wearable device.

[0054] 11 is a schematic screen diagram for explaining another example of a screen displayed on the translation device according to the embodiment. In the example of Fig. 11, the screen of the touch panel 12 is divided into two, upper and lower, as in the example of Fig. 3.

[0055] In the example of FIG. 11, the control unit 11 divides the screen of the touch panel 12 into two screens: a first screen 121G and a second screen 122G.

[0056] 11 , the control unit 11 displays the first screen 121G and the second screen 122G so that the direction for viewing the icon 132G on the first screen 121G and the direction for viewing the icon 135G on the second screen 122G differ by 180° on the touch panel 12. For example, as shown in FIG. 11 , the control unit 11 rotates at least the icon 135G by 180° as the display on the second screen 122G.

[0057] 3, a boundary line is displayed between the first screen 121 and the second screen 122. However, this display is merely an example. For example, as shown in FIG. 11, a boundary line does not need to be displayed between the first screen 121G and the second screen 122G. Note that the dotted line in FIG. 11 is for convenience's sake to indicate the area of ​​the first screen 121G and the area of ​​the second screen 122G, and is not displayed on the screen of the touch panel 12.

[0058] Control unit 11 arranges and displays, on first screen 121G, a box area 131G for selecting a language used by the user of translation device 10, an icon 132G for the user to input speech using microphone 19, a first character display area 125G including text in the first language that is the content (words) of the speech input in the first language, and an icon 136G for converting the text in the first language into speech and outputting it as sound from speaker 18. Box area 131G, icon 132G, and first character display area 125G function in the same way as box area 131, icon 132, and first character display area 125, respectively, described with reference to FIG.

[0059] Furthermore, control unit 11 arranges and displays on second screen 122G a box area 134G for selecting a language used by the other party who speaks a language different from the language used by the user, an icon 135G for the other party to input voice using microphone 19, a second character display area 126G including text in the second language that is the content (words) of the second language that has been input voice-wise, and an icon 136H for converting the text in the second language into voice and outputting it as sound from speaker 18. Box area 134G, icon 135G, second character display area 126G, and icon 136H function in the same manner as box area 134, icon 135, second character display area 126, and icon 136, respectively, described with reference to FIG.

[0060] 11, the control unit 11 displays the status of the radio waves used by the communication circuit 14 (FIG. 2) on one of the two or more divided screens. In the example of FIG. 11, the control unit 11 displays characters 123G indicating the radio wave status.
