  In the present embodiment, the server apparatus 10 is configured as one server apparatus 10 in FIG. 1, but is not limited thereto. For example, the operation performed by the control unit 11 and the operation performed by the communication unit 12 are different servers. You may divide | segment into the apparatus 10 (an arithmetic server apparatus and a delivery server apparatus). That is, the server device 10 may be configured by a plurality of server device groups. In such a case, each server apparatus 10 may be installed in a position away from each other and configured to communicate with each other through a communication network.

  As shown in FIG. 2, the in-vehicle device 20 includes a control unit 21, a communication unit 22, a storage device 23, an information acquisition unit 24, an imaging unit 25, an operation unit 26, a display unit 27, and sound output. A unit 28 and a sound input unit 29.

  The control unit 21 is configured by a CPU including a memory such as a RAM or a ROM, and controls the entire vehicle-mounted device 20.

  The communication unit 22 is connected to a communication network and performs communication with the server device 10. In this embodiment, an example in which the communication unit 22 is provided integrally with the in-vehicle device 20 is shown. However, the communication unit 22 is configured as a separate unit, such as connecting a card-type communication device or a mobile phone with a cable or the like. The vehicle-mounted device 20 may be detachable.

  The storage device 23 is composed of, for example, a hard disk or a non-volatile memory, and stores a program and data for the control unit 21 to control the in-vehicle device 20, for example, a set character code set such as ASCII, etc. Reading and writing are performed under the control of the unit 21.

  The information acquisition unit 24 acquires music information. The information acquisition unit 24 is, for example, a USB input terminal for acquiring music information recorded in a USB memory, an optical reading device for acquiring music information recorded on an optical recording medium such as a CD or a DVD, a smartphone For example, a BT (Bluetooth (registered trademark)) communication unit for acquiring music information recorded in a communication device by communication.

  The sound input unit 29 as a sound collection unit is composed of a microphone or the like, and acquires a user's utterance and the like.

  Next, an example of the operation of the information display system configured as described above will be described with reference to FIG. The flowchart of FIG. 3 is executed by the in-vehicle device 20. Moreover, the control part 21 of the vehicle equipment 20 becomes an information display program which makes a computer execute the information display method by making this flowchart into a computer program.

  When the user operates the operation unit 26 to perform reproduction operation of music information, the control unit 21 of the on-vehicle device 20 acquires the music information from the information acquisition unit 24 and operates the music. The reproduced sound of information is output from the sound output unit 28. In response to the reproduction operation, the in-vehicle device 20 executes the information display process shown in FIG. 3 and displays the tag information of the music information being reproduced on the display unit 27.

  First, the in-vehicle device 20 reads character data included in the tag information of the music information (step S1). Next, the in-vehicle device 20 functions as a first control unit, converts character data based on the set character code stored in the storage device 23, and displays the converted character on the display unit 27 (step S2). For example, if the character data corresponds to Japanese kanji or katakana, but the set character code corresponds to an alphabet such as ASCII or a Cyrillic character, the character is garbled. Note that the garbled character includes a case where there is no corresponding character in the character data and the character data becomes blank.

  Next, the in-vehicle device 20 functions as a detection unit and a second control unit, detects a user reaction to the display, and determines whether to start searching for a character code (step S3). In step S <b> 3, the in-vehicle device 20 determines to start searching for a character code when, for example, there is a predetermined reaction to the movement of the user's eyes from the user's face imaged by the imaging unit 25. If there is a predetermined pattern of eyeball or eyelid movement such as blinking X times or moving the eyeball to the left or right, the in-vehicle device 20 determines that there is a predetermined reaction and starts searching for the character code (in step S3). Y), go to step S4. In step S3, the in-vehicle device 20 determines that the search for the character code is started from the sound input by the sound input unit 29 (for example, voice input when the user utters “No”).

  On the other hand, the in-vehicle device 20 starts the search for an alternative character code without any reaction when the eyeball or eyelid of a predetermined pattern does not move and there is no utterance of “different”. It is determined that it is not necessary (N in step S3), and the process is immediately terminated. In this case, it may be determined that it is not necessary to start the search for an alternative character code after a predetermined time (for example, 10 seconds) has passed.

  In step S4, the in-vehicle device 20 transmits a search command to the server device 10 to cause the server device 10 to start searching for a character code instead of the set character code. When receiving the search command, the server device 10 searches the character code database 13 and transmits one of the plurality of character codes stored in the character code database 13 to the in-vehicle device 20.

  Here, for example, the server device 10 may search for and transmit a character code with a priority according to the language selected by the in-vehicle device 20 among a plurality of character codes. In this case, the in-vehicle device 20 may include information on the selected language in the search instruction.

  Moreover, the server apparatus 10 may analyze the tune of music information, for example, and may search a character code with the priority according to a tune analysis result. Specifically, the server device 10 determines the genre (enka, Russian folk song, samba, tango, Indian dance music, classical music, etc.) of the music information based on the music tone analysis result, and prioritizes according to the language corresponding to the genre. Search for the character code at a degree and send it. For example, if the genre is enka, the server device 10 preferentially transmits a character code corresponding to Japanese, and if it is a Russian folk song, it preferentially transmits a character code corresponding to Russian. Further, the server device 10 may identify the song itself from the music tone analysis result and transmit a character code corresponding to the identified song.

  The in-vehicle device 20 includes part of the music information in the search command in order to cause the server device 10 to perform music tone analysis. As the music information, a part of the music information acquired from the information acquisition unit 24 may be included as it is, or a reproduction sound output from the sound output unit 28 collected by the sound input unit 29 may be included. It may be.

  When receiving the character code (Y in step S5), the in-vehicle device 20 uses the received character code as the substitute character code, converts the character data based on the substitute character code, and displays the converted character (step S6). . Thereafter, the vehicle-mounted device 20 detects the user's reaction again and determines whether to start searching for the character code again (step S7). In step S <b> 7, the in-vehicle device 20 detects the movement of the user's eyes from the user's face imaged by the imaging unit 25. For example, as in step S3, the in-vehicle device 20 determines that the search for the character code is started again if there is a predetermined pattern of eyeball or eyelid movement such as blinking X times or moving the eyeball left and right ( In step S7, Y), the process returns to step S4. Further, if the user speaks, for example, “No”, the in-vehicle device 20 determines that the search for the character code is started again (N in Step S7), and returns to Step S4.

  When returning to step S4, the in-vehicle device 20 transmits a search command to the server device 10 again, and causes the server device 10 to start searching for a character code instead of the set character code. As a result, the server device 10 starts searching for the character code again and transmits one of the character codes not transmitted to the in-vehicle device 20. That is, the server device 10 sequentially transmits character codes each time a search command is received.

  On the other hand, when the on-vehicle device 20 detects a movement of an eye with a pattern different from the predetermined pattern (for example, blinking Y times, moving the eyeball up and down) or when the user utters “this”, for example, again. It is determined that it is not necessary to start searching for an alternative character code (N in step S7), and the process ends. As a result, the alternative character code is determined as the character code of the currently displayed character. In step S7, it is determined that it is not necessary to start searching for a character code even when a blink is not detected even after a predetermined time has elapsed, or when the user does not speak anything (N in step S7), and processing Exit.

  According to the above-described embodiment, the user can simply correct the garbled character because the character converted based on the alternative character code is displayed only by performing a specific reaction.

  According to the embodiment described above, the character code search may be started when there is a predetermined reaction related to the movement of the user's eyes. Thereby, when the user's eye movement that is not in a normal state is detected, a search for an alternative character code is started, and the garbled character can be corrected.

  According to the embodiment described above, the predetermined reaction related to the user's eye movement is a predetermined pattern of eyeball or eyelid movement. By determining an eye movement pattern, a predetermined eye movement can be easily detected.

  According to the above-described embodiment, the server device 10 transmits the character code searched with the priority according to the music tone analysis result of the music information, and the in-vehicle device 20 uses the transmitted character code as a substitute character code. Convert the data. Thereby, an appropriate character code can be searched quickly.

  According to the embodiment described above, the in-vehicle device 20 causes the server device 10 to start searching for a character code by performing communication via the communication unit 22. Thereby, a plurality of character codes need only be stored in the server device 10 and do not need to be stored in the in-vehicle device 20, so that the storage data capacity of the information display device can be reduced and the cost can be reduced.

  According to the embodiment described above, the in-vehicle device 20 causes the server device 10 to start the music tone analysis of the music information via the communication unit 22. Thereby, since a music tone analysis is performed by the server apparatus 10, the processing amount of the vehicle equipment 20 can be reduced.

  According to the above-described embodiment, the in-vehicle device 20 displays the character converted from the character data based on the alternative character code on the display unit 27, and then the character of the character displayed on the display unit 27 based on the reaction of the user. It is determined whether the alternative character code is determined for the code or whether the character code search is started again. Thereby, even when the alternative character code once determined is not correct, a new alternative character code can be easily determined by further user reaction.

  In the above-described embodiment, the user's reaction is detected by detecting the user's eye movement and the user's utterance in steps S3 and S7. However, the present invention is not limited to this. Only one of the user's eye movement and the user's utterance may be detected as the user's reaction. Further, the present invention is not limited to this, and a motion sensor or the like may be provided to detect a change in the user's head or face, arm movement, finger movement, or the like as a user reaction. In other words, the method is limited to the disclosed method as long as the user can detect a surprise that is different from the normal operation on the displayed character, other abnormal reaction, or a predetermined response. Instead, other known techniques may be used to detect the user's reaction.

  In the above-described embodiment, the server device 10 searches for a character code. However, the present invention is not limited to this. For example, a plurality of character codes may be stored in the storage device 23 of the in-vehicle device 20 so that the in-vehicle device 20 searches the storage device 23 for character codes. Moreover, you may make it search a character code in both the server apparatus 10 and the vehicle equipment 20. FIG.

  Moreover, in the Example mentioned above, although the server apparatus 10 performed the music tone analysis, it is not restricted to this. The in-vehicle device 20 may perform the tune analysis.

  Further, according to the above-described embodiment, the in-vehicle device 20 displays a character converted by the character code, and then determines whether it is necessary to detect the user's reaction and start the character code search again. However, it is not limited to this. After displaying the character converted by the alternative character code, the in-vehicle device 20 may end the process as it is without detecting the user's reaction.

  Further, according to the above-described embodiment, the character code is transmitted with the priority based on the tone of music or the language used, but the present invention is not limited to this. For example, it is also possible to learn a substitute character code that has been determined for the source source of the music information and transmit the character code with a priority according to the learning result. Thus, once the music information is reproduced and the music information is acquired again from the source source for which the alternative character code is determined, the alternative character code determined last time is preferentially searched and transmitted. Thereby, an appropriate character code can be searched quickly.

  The information display device described above is not limited to the in-vehicle device 20 but may be a mobile terminal such as a mobile phone or a smartphone that can be used outside a moving body, a tablet personal computer, or the like.
