  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, as described below, a predetermined application program corresponding to the user's state is selected, and the first data is converted into second data having a second format that can be played back by the predetermined application program. The second data is reproduced by a predetermined application program. When applied to a client-server system, for example, data can be converted on a server and transmitted to a user terminal for reproduction. Alternatively, the server may be configured to manage only data and perform data conversion and reproduction within the user terminal. Furthermore, the configuration may be such that data is exchanged between user terminals, and data conversion and reproduction are performed within the user terminals.

  A first embodiment will be described with reference to FIGS. FIG. 1 is an explanatory diagram showing the overall configuration of the data reproduction system. The data reproduction system includes, for example, at least one management server 20 and one or a plurality of user terminals 10A and 10B. The management server 20 and the user terminals 10A and 10B are connected to each other via a communication network CN such as the Internet so that bidirectional communication is possible. The configuration of the management server 20 will be described first, and then the configuration of the user terminals 10A and 10B will be described. In addition, when not distinguishing user terminal 10A and 10B in particular, it will be called the user terminal 10.

  The management server 20 corresponding to the “first computer” includes, for example, a microprocessor, a memory 26, hardware resources such as communication means 25, and software resources such as an operating system and predetermined various programs. When the microprocessor of the management server 20 reads and executes various programs stored in the memory 26, the functions 21 to 24 described later are realized.

  The management server 20 includes, for example, a user location management unit 21, a user information management unit 22, an application program selection unit 23, a data conversion unit 24, a communication unit 25, and a memory 26.

  The user location management means 21 is a function for managing the location of the user. The user position management means 21 can grasp and manage the position of the user by various methods. For example, in one method, a user can access the management server 20 using the user terminal 10 and set his / her position. That is, the user can manually register the user position in the management server 20.

  In another method, the position of the user is automatically detected and managed by using a system capable of detecting position information such as GPS (Global Positioning System) or PHS (Personal Handyphone System). In yet another method, a location management system such as an employee entry / exit management system is used to detect whether the user is present at the workplace.

  The user information management means 22 is a function for managing user information T10. The user information management unit 22 stores in the memory 26 user information T10 input by the user via the user terminal 10. A configuration example of the user information T10 will be described later.

  For example, the application selection unit 23 selects a predetermined application program from a plurality of application programs AP registered in advance based on the user information T10 and the attribute (data format) of the data D1 to be converted.

  The data conversion unit 24 converts the conversion target data D1 into data that can be reproduced by a predetermined application program. The converted data is transmitted to the user terminal 10 via the communication unit 25. Note that the converted data may be stored in the memory 26 and then transmitted to the user terminal 10.

  The communication means 25 is for communicating with the user terminal 10 via the communication network CN. The communication unit 25 includes a communication interface circuit and a communication protocol. The communication means 25 is capable of bidirectional communication with the user terminal 10 by either one or both of wired and wireless.

  The memory 26 as “storage means” is composed of one or a plurality of storage devices such as a flash memory device or a hard disk device. The storage unit 26 stores, for example, user information T10, conversion control information T20, application management information T30, saved data D1, and an application program AP.

  The user information T10 and the conversion control information T20 will be described later again. The application management information T30 is information for managing each application program AP. The application management information T30 manages, for example, each attribute about the name, size, storage address, creator name, creation date / time, update date / time, digital signature, compatibility, etc. of the application program AP.

  The stored data D1 is data stored in the memory 26. In this embodiment, data to be converted (corresponding to first data) is stored in the memory 26. The conversion target data D1 is uploaded and stored from the user terminal 10A in the illustrated example. The management server 20 may read the data stored in the recording medium and save the data in the memory 26.

  The user terminal 10 will be described. In this embodiment, two types of user terminals 10A and 10B are illustrated. One user terminal 10 </ b> A has both a function of uploading and storing data in the management server 20 and a function of reproducing converted data received from the management server 20. The other user terminal 10B has only a data reproduction function. Therefore, the configuration of the user terminal 10A will be described below.

  The hardware configuration of the user terminal 10A will be described later with reference to FIG. The user terminal 10A includes, for example, a communication unit 11, a data reproduction unit 12, an application program 13, a data storage unit 14, and a user information registration unit 15.

  The communication means 11 is a function for performing bidirectional communication with the management server 20 via the communication network CN. The data reproduction means 12 is a function for reproducing the converted data using a predetermined application program.

  As the application program 13, for example, document creation software, drawing software, spreadsheet software, presentation software, audio reproduction software (here, music is also included in audio), video reproduction software, still image reproduction software, audio Software for converting characters into characters, software for converting characters into Braille, and the like.

  For convenience of explanation, the application program in the management server 20 is denoted by reference sign AP, and the application program in the user terminal 10 is denoted by reference sign 13. Application programs can be divided into three types according to the purpose of use. One is an application program (data creation software) for creating data, and the other is an application program (playback software) used for reproducing data, and the other one. Is an application program (conversion software) used to convert data.

  Since data conversion is performed in the management server 20, the application program AP in the management server 20 is mainly conversion software. Since the converted data is reproduced in the user terminal 10, the application program 13 is mainly reproduction software.

  The data storage unit 14 has a function of uploading data created by the application program 13 to the management server 20 via the communication unit 11 or the like. The user information registration means 15 is a function for creating user information T10 and registering it in the management server 20.

  FIG. 2 shows a hardware configuration of the user terminal 10A. The user terminal 10A is configured as a computer such as a personal computer, a mobile phone, a portable information terminal, or the like. The user terminal 10A includes, for example, a microprocessor (“CPU”: Central Processing Unit) 110, a memory 120, an auxiliary storage device 130, a communication interface 140, a speaker 150, a display 160, a keyboard switch 170, and the like. The microphones 180 and 110 to 180 are connected to a bus 190.

  In addition to the application program 13, the memory 120 stores programs for realizing the data reproduction unit 12, the data storage unit 14, and the user information registration unit 15. The microprocessor 110 exhibits predetermined functions by reading and executing the application program 13 and each program.

  The auxiliary storage device 130 stores, for example, data D1 before conversion and data D2 after conversion. The data D1 before conversion is uploaded to the management server 20 by the data storage unit 14 and stored in the memory 26 of the management server 20. The converted data D2 is transmitted from the management server 20 to the user terminal 10A and stored in the auxiliary storage device 130. The converted data D2 is reproduced by a predetermined application program 13 selected from each application program 13 stored in the memory 120.

  The communication interface 140 corresponds to the communication unit 11 in FIG. The speaker 150 and the display 160 are information output devices for transmitting information to the user. The keyboard switch 170 and the microphone 180 are information input devices for the user to input information to the user terminal 10A. The information output device and the information input device are not limited to those described above, and various devices such as a braille display, a tablet, and a touch panel can be used.

  3 to 5 show an example of the user information T10. User information T10 is created and stored for each user. As shown in FIG. 3, the user information T10 manages, for example, a viewing restriction C10, a place C11, an input data format C12, and a reproduction desired application C13 in association with each other.

  The viewing restriction C10 corresponds to “viewing restriction information”. The viewing restriction C10 stores information indicating a restriction on the user's audiovisual sense. When the user is a healthy person, information indicating “none (no restriction)” is set in the viewing restriction C10. As shown in FIG. 4, when the user has a hearing impairment, information indicating that there is “auditory impairment” is set in the viewing restriction C <b> 10. As shown in FIG. 5, when the user has a visual impairment, information indicating that “visual impairment” is set in the viewing restriction C <b> 10.

  The location C11 corresponds to “classification information”. In the place C11, information indicating a classification according to the position of the user is set. Examples of location classifications include “workplace”, “home”, “destination”, and the like. The user can also create a new category such as “Hotel”, “Airport”, etc.

  The location to which the user belongs can be determined manually or automatically. For example, the user can set the place C11 to “work” or “home” by using the user information registration unit 15 even though the user is actually in the coffee shop. Or it is good also as a structure which detects a user position automatically using the GPS function etc. of the mobile telephone which a user possesses, and transmits the detected position to the management server 20 from the user terminal 10.

  The input data format C12 indicates the format of the conversion target data D1, and corresponds to the “first format”. For example, a text data format, a moving image data format, an audio data format, and the like are set as the input data format C12. Information set in the input data format C12 can be manually changed, added, or deleted by the user.

  The reproduction desired application program C13 corresponds to a “predetermined application program”. Examples of the reproduction desired application C13 include document creation software, presentation software, audio reproduction software, and moving image reproduction software as described above.

  Focusing on the user information T10 (1) of the healthy person shown in FIG. 3, when viewing “voice data” at “workplace”, “text editor” is selected. For example, when audio data recording a meeting content is reproduced at work, the user designates a text editor so as not to disturb others. In this case, the audio data D1 of the conference content is converted into character data D2 in the management server 20 and transmitted to the user terminal 10.

  The user terminal 10 selects and activates a text editor from among the application programs 13 stored in the memory 120, and reproduces the character data D2 of the conference content. Thereby, the user can use what was originally voice data as character data.

  Focusing on the user information T10 (2) of the hearing impaired person shown in FIG. 4, the moving image data is reproduced by the image player P1 and the text editor regardless of the place C12, and the sound data is reproduced by the text editor. It is supposed to be played. Since there is an impairment in hearing, the voice part is converted into character data. The image part is reproduced as it is.

  Focusing on the visually impaired user information T10 (3) shown in FIG. 5, the character data is basically reproduced by the audio player A1. In the case of “Home”, the character data is reproduced by both the audio player A1 and the Braille application. The Braille application is for displaying character data on a Braille display as Braille.

  Note that the application program associated with “Destination” in FIGS. 3 to 5 may be the same as or different from the application program associated with “Work” or “Home”. .

  For example, the image player P1 is selected when a moving image is reproduced at “work” or “home”. The other image player P2 is selected when the moving image is played at “destination”. The user terminal 10 used at “work” or “home” is often a personal computer, but the user terminal used at “destination” is more than a personal computer such as a mobile phone or a personal digital assistant. It may be a device with low data processing capacity. In this embodiment, the user can select an application program according to the capability of the user terminal 10.

  FIG. 6 shows a configuration example of the conversion control information T20. The conversion control information T20 is information for managing a processing procedure for converting the input data D1 into data D2 that can be reproduced by a predetermined application program 13.

  The conversion control information T20 manages, for example, the input data format C20, the reproduction desired application C21, and the conversion procedure C22 in association with each other. The input data format C20 indicates the format of the conversion target data, similar to the input data format C10 described with reference to FIGS. The reproduction desired application C21 indicates an application program used for reproducing data, similarly to the reproduction desired application C13 described with reference to FIGS.

  The conversion procedure C22 indicates a processing procedure for converting data to be converted into data that can be reproduced by a desired application program. For example, when character data is reproduced by the audio players A1 and A2, the character data is input to software for converting the character data into audio data, and converted into audio data. In addition, for example, when audio data is reproduced by a Braille application program, the audio data is converted into character data using software for converting the audio data into character data.

  The overall operation of the data reproduction system will be described with reference to FIGS. Here, a case will be described in which data is created on one user terminal 10A and uploaded to the management server 20, and the user terminal 10B downloads and reproduces the data.

  In the user terminal 10A, the application program 13 is started by a user instruction (S10). Here, it is assumed that the application program 13 for recording the contents of the conference is started. The application program 13 creates audio data of the conference content (S11). The user terminal 10A transmits the created audio data to the management server 20 and requests storage (S12).

  When the management server 20 receives the audio data from the user terminal 10A (S13), it stores it in the memory 26 (S14).

  Other users access the management server 20 using the other user terminal 10B, and create their own user information T10 (S20). The management server 20 stores the created user information T10 (S21).

  Thereafter, the other user accesses the management server 20 and requests reproduction of desired data (S30). The management server 20 acquires the position of the user terminal 10B (S31), and executes a data conversion process (S32). Details of the data conversion processing will be described with reference to FIG. The management server 20 transmits the converted data (for example, character data) to the user terminal 10B (S33).

  The user terminal 10B receives the converted data and reproduces it with a predetermined application program (S34). A user can not only create his / her user information T10 but also create user information T10 of other users and register it in the management server 20.

  FIG. 8 is an example of the data conversion process indicated by S32 in FIG. The management server 20 specifies the format of the input data, that is, the format of the conversion target data (S40), and refers to the user information T10 associated with the user who desires data reproduction (S41).

  The management server 20 specifies the application program C13 that the user desires to reproduce based on the location C11 to which the user's position belongs acquired in S31 and the input data format C12 specified in S40 (S42).

  The management server 20 refers to the conversion control information T20 (S43) and determines whether or not conversion is necessary (S44). For example, when audio data is played back by an audio player, it is not necessary to convert the audio data into data of another format. On the other hand, when audio data is reproduced by a text editor, the audio data must be converted into data in a format that can be used by the text editor.

  When data conversion is necessary (S44: YES), the management server 20 converts the input data (here voice data) into other data (here character data) in a predetermined format based on the conversion procedure C22 of the conversion control information T20. (S45). For the conversion, an application program for converting voice data into character data is used. If conversion is not necessary (S44: YES), S45 is skipped and the process ends.

  According to the present embodiment configured as described above, a predetermined application program can be selected according to the user's state, converted into data in a format usable by the predetermined application program, and reproduced. In the present embodiment, it is not necessary for the user to manually select an application program when reproducing data, and it is not necessary to manually operate conversion processing for reproduction with a desired application program. Therefore, in this embodiment, a predetermined application program can be automatically selected according to the user's condition, data can be automatically converted as necessary, and can be automatically reproduced by the predetermined application program. Usability is improved.

  In this embodiment, a reproduction application program (predetermined application program) can be set in advance for each input data format according to the location to which the user belongs, so that an application program suitable for the user's situation is automatically selected. The data can be converted and reproduced.

  In the present embodiment, the management server 20 manages the user information T10, stores the conversion target data, and converts the conversion target data based on the user information T10 and the like. The user terminal 10 receives and reproduces the converted data. Therefore, the processing load on the user terminal 10 can be reduced, and the present system can be used by using the user terminal 10 having a relatively low processing capability such as a mobile phone.

  In the present embodiment, a predetermined application program can be changed depending on the location to which the user belongs. For example, in a “workplace” or “home” where the user terminal 10 having a relatively high processing capability is used, an application program with a relatively high memory consumption and processor usage rate can be used. In addition, in the “destination” where the user terminal 10 having a relatively low processing capability is used, an application program having a relatively low memory consumption and processor usage rate can be used.

  Note that the converted data may be executed by the application program AP in the management server 20, the execution result is transmitted to the user terminal 10, and the user terminal may display the execution result on a web browser. In this case, the user terminal 10 does not need to have the application program 13 and may have a web browser.

  A second embodiment will be described with reference to FIGS. Each of the following embodiments including this embodiment corresponds to a modification of the first embodiment. Accordingly, the following embodiments will be described with a focus on differences from the first embodiment. In this embodiment, the user terminal 10 manages user information T10, stores data, converts data, and reproduces data.

  FIG. 9 is an overall configuration diagram of the data reproduction system according to the present embodiment. The management server 20 of the present embodiment stores the data D1 received from the user terminal 10 and distributes it in response to a request from the user terminal 10. The management server 20 of this embodiment does not have a function of managing user information T10, a function of selecting an application program, and a function of converting data. Those functions are transferred to the user terminal 10A. The user terminal 10B may be used, but the user terminal 10A will be described as a representative.

The application selection unit 105 selects an appropriate application program 13 according to the format of the user information T10 and data D1 and the location to which the user belongs.

  The data conversion means 106 is a function for converting the data D1 into data of a predetermined format so that it can be reproduced by the selected application program 13. The data reproduction means 107 is a function for reproducing the converted data by the selected application program 13. The data storage means 108 has a function of creating data D1 using the application program 13 and uploading it to the management server 20.

  In the memories 120 and 130, user information T10, data D1, conversion control information T20, application management information T30, and a plurality of application programs 13 are stored. The user terminal 10B has the same configuration as the user terminal 10A.

  FIG. 10 is a flowchart showing the operation of the data reproduction system according to this embodiment. Here, for the sake of convenience, an example in which the user terminal 10A acquires the data created by the user terminal 10B from the management server 20, converts the data as necessary, and reproduces the data with the selected application program 13 selected.

  For example, the user terminal 10B activates a recording application program to record the content of the conference (S60), and creates data (for example, voice data) (S61). The created data is transmitted to the management server 20 (S62).

  The management server 20 receives data from the user terminal 10B (S63) and stores it in the memory 26 (S64).

  On the other hand, in the user terminal 10A, user information T10 is created in accordance with a user instruction and stored in the memory 120, 130 (S70). When the user instructs the user terminal 10A to reproduce data (S71), the user terminal 10A requests the management server 20 to transmit data and acquires data from the management server 20 (S72, S73).

  The user terminal 10A executes the data conversion process described in FIG. 8 (S74), and the converted data is reproduced by the predetermined application program 13 (S75).

  Configuring this embodiment like this also achieves the same effects as the first embodiment. Furthermore, in this embodiment, since the user information T10 is managed in the user terminal 10, there is no need to transmit the user information T10 to the outside of the user terminal 10, and there is a possibility that the presence or absence of an audiovisual failure is known. It can reduce and protect privacy.

  A third embodiment will be described with reference to FIG. FIG. 11 is a flowchart showing the operation of the data reproduction system according to this embodiment. In this embodiment, data is directly exchanged between the user terminals 10 without going through the management server 20.

  For example, the user terminal 10B activates the application program (S80), creates data (S81), and stores it in the memory 120, 130 (S82).

  In the user terminal 10A, user information T10 is created in accordance with a user instruction, and is stored in the memory 120, 130 in the user terminal 10A (S90). When the user instructs data reproduction (S91), the user terminal 10A requests the user terminal 10B to transmit data (S92). In response, the user terminal 10B sends the data stored in S82 to the user terminal 10A. Transmit (S83).

  The user terminal 10A performs the data conversion process described in FIG. 8 on the received data (S93), and reproduces the converted data by a predetermined application program (S94).

  Configuring this embodiment like this also achieves the same effects as the first and second embodiments. Furthermore, in this embodiment, the system configuration can be simplified because the data is directly exchanged between the user terminals 10 without using the management server 20.

  In addition, this invention is not limited to each Example mentioned above. A person skilled in the art can make various additions and changes within the scope of the present invention. The case where voice data is converted into character data has been described as an example. However, the present invention is not limited thereto, and character data can be converted into voice data, or character data can be converted into Braille data.

  Also, a conversion policy may be defined in advance according to the type of audiovisual failure, and a predetermined application program may be automatically selected according to the conversion policy. For example, in the case of a visually impaired user, a conversion policy is set in advance in which character data (or character data included in moving image data, etc.) is converted into audio data, and other types of data are used as they are by default application programs. If this is done, there is no need to set an application program for each input data format, which increases the convenience for the user.
