On the basis of the reproduction history received from each mobile terminal, the server calculates taste information indicating taste for music data per user, calculates proximity information indicating closeness of taste between users on the basis of the taste information on each user and the positional information during reproduction in the music data, and transmits the proximity information to a requesting first mobile terminal. On the basis of the proximity information, the first mobile terminal displays the proximity of taste on music data between the user of the first mobile terminal and users of other mobile terminals on a screen.SELECTED DRAWING: Figure 4

Description

  The present invention relates to a communication support system, and more particularly, to a communication support system for supporting communication between persons with similar preferences among users of mobile terminals.

  In recent years, communication systems via the Internet such as SNS (Social Networking Service) have become widespread. These systems provide support for searching for users who are similar in the field of interest such as music.

  For example, Patent Literature 1 discloses a technology related to a community server that builds a community based on music data that a user likes. The technique according to Patent Literature 1 first generates acoustic feature data by performing vector quantization from music data that each user likes, and obtains a user profile. Then, users having similar user profiles are set as similar users.

  Patent Document 2 discloses a technique related to a user information processing apparatus that calculates similarity between users based on the usage status of users with respect to content. In particular, the technology according to Patent Document 2 calculates calculation processing by recalculating only the combination of users whose values have changed since the most recent similarity calculation when updating the similarity between users. To improve efficiency.

  Here, there is still a barrier between the users having a specific purpose and the state of obtaining information and communicating including face-to-face. For example, a user is interested in a specific artist (singer or group). Furthermore, the artist wants to interact with people who are not just fans of the same artist but also have a close taste for music.

  In that case, first, the user usually finds and browses the official site of the artist or the site (blog or the like) of the artist by WEB search or the like. Thereby, it is possible to obtain various information about the artist such as fan clubs, past live and future live schedules, original goods, and the like. However, since the information is enormous, it is difficult to determine information close to its own taste from the information.

  Therefore, as a next step, among the fans, a user's blog or a simple blog that transmits useful information to himself / herself is identified, and a user close to his / her preference is selected.

  Furthermore, in order to interact with users who are close to their tastes, it is possible to search for the user using another prominent message service (which seems to have a large number of registered users of the artist's fan) and approach the friend application Conceivable. And after a friend application passes, a contact address is exchanged and finally the user with close preference can be in direct contact now.

  Or, when going to the artist's live, there are cases where he / she wants to meet users who seem to be close to the taste from information on the net at the live venue, and then continue to communicate including face-to-face and non-face-to-face. However, there are many people in the live venue that are common in terms of interest in the artist, so it is extremely difficult to find new acquaintances with closer tastes.

  In this way, in order for users to reach information that is close to their preferences using existing SNS, etc., and to reach a state in which users can communicate face-to-face, multiple services are used properly according to the stage and situation. There is a problem that it is necessary to narrow down a huge amount of information by spending a lot of time and effort. Even in that case, it is often difficult to determine whether the found user is actually close to his / her values.

  Here, a user having a portable terminal capable of reproducing music data can reproduce desired music data at a place or time zone that the user prefers. However, in Patent Documents 1 and 2 described above, the aspect of movement of the mobile terminal is not considered as a measure for determining the user's preference. For this reason, the accuracy of deriving users with similar preferences is not sufficient, and it is insufficient to solve the above-described problems.

  The present invention has been made to solve such problems, and is a communication support system for assisting in finding a user whose specific preference approximates with high precision and easily taking communication including face-to-face. The purpose is to provide.

The communication support system 100 includes a plurality of portable terminals 21, 22,... 2n, a base station 31, a network 32, and a server 40.

  Each of the portable terminals 21 to 2n is a portable terminal device that is owned and operated by different users and capable of wireless communication. 1 shows that the mobile terminal 21 is owned and operated by the user 11, the mobile terminal 22 by the user 12,... And the mobile terminal 2n by the user 1n. However, a single mobile terminal may be shared by a plurality of users, and the login user for the system according to the present embodiment may be switched and used. Moreover, in this Embodiment, a user and a portable terminal should just be at least 2 or more.

  Each of the portable terminals 21 to 2n can play back predetermined music data by the operation of each user. Here, the music data is acquired from the outside of the mobile terminal by downloading or the like, and is stored permanently or temporarily inside. Each of the mobile terminals 21 to 2n may store a plurality of types of music data. Furthermore, it is assumed that at least one of music data stored in each portable terminal is common. In addition, each of the mobile terminals 21 to 2n can acquire current position information by GPS (Global Positioning System) or the like. For this reason, the mobile terminal according to the present embodiment is, for example, a mobile phone capable of reproducing music data and equipped with a GPS function, a portable music player capable of wireless communication, and capable of acquiring position information. Can be applied to.

  Here, FIG. 2 is a block diagram showing a configuration of the mobile terminal according to the first exemplary embodiment of the present invention. In FIG. 2, the mobile terminal 21 will be described as a representative, but the mobile terminals 22 to 2n are the same, and thus illustration and description thereof are omitted.

  The mobile terminal 21 includes a storage unit 211, a playback unit 212, a communication unit 213, a display unit 214, a position information acquisition unit 215, a screen 216, a speaker 217, and a control unit 218. The storage unit 211 is realized by a volatile and non-volatile storage device. The storage unit 211 stores a user ID 201, music information 202, a reproduction history 203, and current position information 204. In addition to these, the terminal ID is stored, but is not shown.

  The user ID 201 is identification information for identifying the user 11, and is, for example, a login ID. The music information 202 includes music data 2021 and attribute information 2022. The music data 2021 is electronic data corresponding to a sound source reproduced by the mobile terminal 21. The music data 2021 includes music data. The attribute information 2022 is information indicating attributes of the music data 2021. The attribute information 2022 is, for example, music data identification information, title information (song name, album name, etc.), artist information, and the like. Note that the music information 202 may include a set of a plurality of types of music data 2021 and attribute information 2022.

  The reproduction history 203 is history information for each music data 2021 reproduced on the mobile terminal 21. That is, the reproduction history 203 is associated with the identification information (attribute information 2022) of the music data 2021. Furthermore, the reproduction history 203 is associated with a user ID 201 or a terminal ID (not shown).

  The playback history 203 includes a playback count 2031, a final playback date / time 2032, a skip count 2033, and playback position information 2034. The number of times of reproduction 2031 is a cumulative value of the number of times of reproduction within a predetermined period per music data. The last reproduction date / time 2032 is the date / time of the last reproduction in the corresponding music data. A date may be used instead of the date. Furthermore, not only the last reproduction date and time but also each reproduction date and time within a predetermined period may be stored. Alternatively, the most recent N playback times (N is a natural number of 2 or more) may be held. The skip count 2033 is a cumulative value of the number of skip operations performed before the music data reproduction ends. For example, a case where a skip operation is performed without playing among a plurality of music in an album, a case where a skip operation is performed during playback, and the like are applicable.

  The reproduction position information 2034 indicates position information at the time of reproduction of music data among current position information 204 described later. Since the current position information is updated every time the mobile terminal 21 moves and is reacquired, the location when the user 11 reproduces the music data 2021 is included in the reproduction history 203 and recorded.

  The current position information 204 is current position information in the mobile terminal 21. As the position information, latitude and longitude information provided by GPS or the like, wireless access point identification information, or the like can be used.

  Note that the storage unit 211 stores client software, which is a computer program for the mobile terminal 21 according to the present embodiment, as a configuration (not shown).

  The control unit 218 is a control device such as a processor. The control unit 218 controls various processes in the mobile terminal 21, access to the storage unit 211, the playback unit 212, the communication unit 213, the display unit 214, the screen 216, the speaker 217, and the like. Then, the control unit 218 reads and executes a program or the like stored in the storage unit 211. Thereby, the control part 218 implement | achieves the various functions of the portable terminal of the communication assistance system 100 at least. Note that the playback unit 212, the communication unit 213, and the display unit 214 are not limited to software, and may be realized in whole or in part by hardware.

  The reproduction unit 212 performs a process of reproducing the music data 2021 specified by the operation of the user 11. Then, the control unit 218 updates the reproduction history 203 corresponding to the music data reproduced by the reproduction unit 212. The control unit 218 counts up the number of reproductions 2031 of the music data and updates the last reproduction date 2032 during reproduction by the reproduction unit 212. In addition, when the skip operation is performed on the music data, the control unit 218 increments the skip count 2033. Further, the control unit 218 records the current position information 204 at the time of reproduction included in the reproduction history 203 as position information 2034 at the time of reproduction.

  The communication unit 213 communicates with the server 40 via the base station 31 and the network 32. That is, the control unit 218 transmits data to the server 40 by the communication unit 213 and receives data from the server 40. For example, the control unit 218 transmits the reproduction history 203 to the server 40 through the communication unit 213 at a predetermined opportunity. The control unit 218 transmits the corresponding music data attribute information 2022 and user ID 201 (or terminal ID) to the server 40 via the communication unit 213 together with the reproduction history 203. Further, the control unit 218 transmits a request for proximity information with another user, which will be described later, to the server 40 by the communication unit 213 according to the operation of the user 11. Further, the control unit 218 receives proximity information from the server 40 via the communication unit 213.

  The display unit 214 displays display data for accepting the operation of the user 11 on the screen 216. Further, the display unit 214 is based on the closeness information received by the communication unit 213, and the closeness of preference regarding the music data between the user 11 in the mobile terminal 21 and the other users 12 to 1n in the other mobile terminals 22 to 2n. Is displayed on the screen 216.

  The location information acquisition unit 215 acquires the current location information of the mobile terminal 21 from GPS or the like, and the control unit 218 stores the current location information 204 in the storage unit 211.

  The screen 216 is a display data output device in the mobile terminal 21. The speaker 217 is an output device for sound data and the like when reproducing music data.

  Returning to FIG. The server 40 is a computer device that communicates with the mobile terminals 21 to 2n via the base station 31 and the network 32. The server 40 calculates preference information and proximity information according to the present embodiment, and transmits the proximity information in response to requests from the mobile terminals 21 to 2n.

  The server 40 includes a storage unit 41, a communication unit 42, and a control unit 43. The storage unit 41 is realized by a volatile and non-volatile storage device. The storage unit 41 includes preference information 411 and proximity information 412. The preference information 411 is information indicating the degree of preference regarding music data for each user. The preference information 411 includes information indicating the degree of preference for each music data and information indicating the degree of preference of specific music data in all music data reproduced by a certain user.

  The proximity information 412 is information indicating the degree of preference approximation between users.

  The server 40 may manage the playback history 203 for each mobile terminal and music data instead of the mobile terminals 21 to 2n. In that case, the mobile terminals 21 to 2n transmit the music ID, the user ID (or terminal ID), and the current position information 204 to the server 40 every time the music data is reproduced, and the server 40 stores the information based on the received information. In the unit 41, the current position information 204 is stored as reproduction position information 2034 and the music ID and the user ID corresponding to the reproduction history 203 are stored.

  The storage unit 41 may manage information in which the user ID and the terminal ID are associated with each other. And when the user who carries each portable terminal respond | corresponds on a one-to-one basis, each portable terminal may transmit terminal ID instead of transmitting user ID. The server 40 can identify the user ID from the received terminal ID by referring to the storage unit 41.

  The communication unit 42 communicates with the mobile terminals 21 to 2n via the base station 31 and the network 32. That is, the communication unit 42 receives data from each of the mobile terminals 21 to 2n and returns data to any mobile terminal. For example, the communication unit 42 receives the playback history 203 and the like transmitted from each of the mobile terminals 21 to 2n at a predetermined opportunity. In addition, the communication unit 42 receives a request for proximity information with another user from an arbitrary mobile terminal, and returns the proximity information to the requesting mobile terminal.

  The control unit 43 is a control device such as a processor. The control unit 43 stores the playback history 203 and the like received from the mobile terminals 21 to 2n by the communication unit 42 in the storage unit 41 in association with the user and the set of music data. Then, the control unit 43 calculates the preference information 411 for each user and for each music data based on the stored reproduction history. At this time, the control unit 43 calculates the preference information 411 so that the degree of preference increases as the number of times of reproduction 2031 increases. In addition, the control unit 43 calculates the preference information 411 so that the degree of preference becomes higher as the last reproduction date 2032 is closer to the current date. For example, for a certain piece of music data, if the number of reproductions of user A is “3” and the number of reproductions of user B is “2”, the preference information of user A is calculated to be higher than the preference information of user B. In addition, when the playback counts of the users A and B are both “2” and the final playback date and time are both “6/9 21:00”, since the playback count and the final playback date and time are the same, the preference information is also included. It becomes the same value.

  Further, the control unit 43 may calculate the preference information 411 so that the degree of preference becomes higher as the most recent reproduction date and time increases even if the number of times of reproduction 2031 is the same among a plurality of users or music data. In the above example, when the two most recent playback dates / times are recorded, for example, the playback date / time of user A is “6/9 21:00” and “6/8 20:00”, and user B ’s When the reproduction date / time is “6/9 21:00” and “5/30 19:00”, the preference information of the user A may be calculated higher than the user B.

  In addition, the control unit 43 calculates the preference information 411 so that the degree of preference decreases as the skip count 2033 increases. Thereby, thinness of interest can be reflected in the degree of preference.

  In addition, the control unit 43 calculates the proximity information 412 based on the preference information 411 of each user and the reproduction position information 2034 in the music data. At this time, the control unit 43 calculates the proximity information 412 so that the closer the value of the preference information 411 in the same music data is, the higher the degree of preference similarity between the users in the music data is. . This is because users with high preference information about the same music data can be said to have similar preferences about the music data. Conversely, even if the preference information about the same music data is not so high, it can be said that the preference is approximated if the preference information is close to each other.

  Further, the control unit 43 calculates the approximation information 412 so that the degree of the approximation becomes higher as the last reproduction date 2032 is closer. In particular, even if the playback date / time is not the most recent, if the last playback date / time of each other is about the same as the current date, it can be said that the interest in the music data is low. It is because it can be said that is approximate.

  When the reproduction history 203 includes a plurality of reproduction dates and times, the control unit 43 calculates the proximity information 412 so that the closer the combination of the reproduction dates and times, the higher the degree of approximation.

  Further, the control unit 43 calculates the approximation information 412 so that the degree of approximation becomes high even when the reproduction position information 2034 is close for the same music data. This is because users who play the same music data under the same environment can be said to have similar preferences.

  Further, the control unit 43 calculates the approximation information 412 so that the degree of approximation becomes high even when the skip count 2033 is close for the same music data. This is because it can be said that the interests of the music data are close to each other, and it can be said that the preferences of both users are approximate.

  Further, the control unit 43 may calculate the proximity information 412 so that the closer the current position information 204 is, the higher the degree of proximity is.

  And the control part 43 transmits the said proximity information to the portable terminal which requests the calculated proximity information.

  The storage unit 41 stores server software and the like as a configuration (not shown). The control unit 43 controls various processes in the server 40, access to the storage unit 41 and the communication unit 42, and the like. Therefore, the control unit 43 reads and executes a program stored in the storage unit 41. Thereby, the control part 43 implement | achieves the function of the server 40 mentioned above at least.

  The base station 31 is wirelessly connected to the mobile terminals 21 to 2n, and is connected to the server 40 via the network 32. However, the base station 31 is not necessarily one, and each mobile terminal may be connected to a different base station.

  The network 32 is a communication line network such as the Internet and a cellular phone communication network connected to the Internet, and is a well-known network, so detailed description thereof is omitted.

(Replay history update and transmission processing)
FIG. 3 is a flowchart for explaining the flow of the playback history update and transmission process in the mobile terminal 21 according to the first embodiment of the present invention. In addition, since the process of the portable terminals 22-2n is also equivalent, description is abbreviate | omitted.

  First, the control unit 218 causes the reproduction unit 212 to reproduce the music data 2021 designated by the operation of the user 11 (S11). Specifically, the control unit 218 reads the designated music data 2021 from the storage unit 211, starts the reproduction process by the reproduction unit 212, and outputs it via the speaker 217.

  Further, the position information acquisition unit 215 acquires the current position information of the mobile terminal 21 (S12). Then, the control unit 218 stores the position information acquired by the position information acquisition unit 215 in the storage unit 211 as current position information 204. Note that step S12 need not be executed in parallel with step S11 and does not depend on the execution of step S11. For example, it may be executed at predetermined intervals.

  Next, the control unit 218 records the acquired current position information 204 as reproduction position information 2034 in the reproduction history 203 (S13). That is, the control unit 218 updates the playback history 203 relating to the played music data immediately after step S11 (during playback) or after the end of playback. For example, the control unit 218 increments the reproduction count 2031 and updates the last reproduction date 2032. Or the control part 218 adds and preserve | saves reproduction | regeneration date. If the user 11 performs a skip operation during reproduction of the music data, the control unit 218 increments the skip count 2033. Even when the user 11 performs a skip operation without playing music data, the control unit 218 counts up the skip count 2033. Further, the control unit 218 includes the current position information 204 saved in the storage unit 211 as reproduction position information 2034 in the reproduction history 203 and saves it. As a result, even if the current position information 204 is updated thereafter, the reproduction position information 2034 in the reproduction history 203 is retained.

  Thereafter, the mobile terminal 21 determines whether or not it is a predetermined opportunity (S14). Here, the predetermined trigger is, for example, at the start of reproduction of music data, immediately after the end of reproduction, immediately after activation of the mobile terminal 21, any arbitrary timing scheduled in advance, periodic timing, or operation of the user 11 The timing explicitly specified by.

  When it determines with it not being a predetermined opportunity in step S14, the position information acquisition part 215 acquires the present position information of the portable terminal 21 after progress for a predetermined time (S15). Then, the control unit 218 overwrites and stores the position information acquired by the position information acquisition unit 215 in the storage unit 211 as current position information 204.

  On the other hand, when it determines with it being a predetermined opportunity in step S14, the control part 218 transmits the reproduction | regeneration log | history 203 and the newest present position information 204 to the server 40 by the communication part 213 (S16). At this time, the control unit 218 further transmits the attribute information 2022 of the music data corresponding to the reproduction history 203 and the user ID 201 (or terminal ID) to the server 40. That is, the control unit 218 reads the user ID 201, the attribute information 2022, the reproduction history 203, and the current position information 204 from the storage unit 211 and transmits them to the server 40 through the communication unit 213. Since the playback history 203 includes the playback position information 2034 and the like as described above, it can be said that the control unit 218 transmits the playback position information 2034 and the like to the server 40 by the communication unit 213.

  Subsequently, a user search according to the first embodiment of the present invention will be described. The user search function of the communication support system 100 according to the present embodiment recommends a user who has a high possibility of having a similar taste to music as a friend candidate. Furthermore, according to the present embodiment, it is possible to recommend users who are close to each other as well as having similar preferences. In the following, it is assumed that the user 11 searches for a user who is similar to his / her preference and is physically close.

(User search)
FIG. 4 is a sequence diagram illustrating the flow of the user search according to the first embodiment of the present invention. First, the portable terminal 21 transmits the reproduction history 203, the current position information 204, and the like to the server 40 as in step S16 (S21). Then, the server 40 stores the reproduction history 203 and the current position information 204 received from the mobile terminal 21 in the storage unit 41 in association with the user ID of the user 11 and the attribute information of the music data (S22). For example, the control unit 43 of the server 40 digitizes the combination of title information and artist information included in the attribute information of the music data corresponding to the received reproduction history 203, and the number of reproductions 2031 and the last reproduction date and time 2032 etc. are converted into the numerical values. Associate.

  Similarly, the portable terminal 22 transmits the reproduction history 203 and the current position information 204 and the like to the server 40 (S23), and the server 40 transmits the reproduction history 203 and the current position information 204 received from the portable terminal 22 to the user 12 user. The ID and music data attribute information are stored in the storage unit 41 in association with each other (S24). The portable terminal 2n transmits the reproduction history 203 and the current position information 204 to the server 40 (S25), and the server 40 uses the reproduction history 203 and the current position information 204 received from the portable terminal 2n as the user ID of the user 1n. And stored in the storage unit 41 in association with the attribute information of the music data (S26).

  The order of steps S21, S23, and S25 is not limited to this, and they may be arranged in parallel. Further, the order of steps S22, S24 and S26 is not limited to this. Steps S22, S24, and S26 need not be executed every time they are received, and may be executed together at a predetermined timing.

  Subsequently, the control unit 43 of the server 40 calculates the preference information 411 for each user (S27). That is, the control unit 43 calculates preference information 411 related to music data for each user based on the reproduction history 203 of each mobile terminal. For example, the control unit 43 calculates the preference information 411 for music data corresponding to the reproduction history of the user 11. At this time, the control unit 43 calculates numerical values in consideration of the number of times of reproduction 2031, the last reproduction date / time 2032, the number of times of skipping 2033 included in the reproduction history 203. For example, the control unit 43 calculates, as the preference information 411, a larger value as the number of reproductions 2031 is larger, the last reproduction date and time 2032 is closer to the current date, and the number of skips 2033 is smaller.

  When the reproduction history 203 for a plurality of music data is stored for the user 11, the control unit 43 calculates preference information 411 for each music data. Then, the control unit 43 converts the calculated preference information for each piece of music data into the degree of preference (points) of each piece of music data in all the music data reproduced by the user 11. For example, the preference information of each music data may be calculated as the standard deviation in all music data of the user 11. That is, based on all the songs that a certain user has played within the past N days, how much the user likes to play the song X is pointed by a numerical value. Thereby, the bias | biasing between users can be reduced.

  For example, it is assumed that the number of reproductions of the song X and the last reproduction date / time are the same for the user A and the user B. However, it is assumed that user A has played 100 songs including song X in the past 15 days, and user B has played only 10 songs including song X. In such a case, the values of the preference information calculated independently for the song X are the same values for the users A and B. However, in this situation, it can be said that the user A and B have different degrees of preference because the degree of relative number of reproductions with respect to the song X is different. Therefore, the degree of preference of each song in all songs reproduced for each user is replaced with, for example, a deviation value method with 50 as a reference value. Thereby, the preference degree in the music X between the users A and B can be calculated as separated values, and the preference degree between users can be expressed more accurately.

  Thereafter, the control unit 43 of the server 40 calculates the closeness information 412 between users (S28). That is, the control unit 43 calculates the proximity information 412 between users based on the preference information 411 of each user and the position information 2034 at the time of reproduction in music data.

  For example, the control unit 43 selects a set of users whose preference information about the same music data is calculated from a plurality of users. And about the group of the selected user, the control part 43 plots each user's point (preference information) on a straight line, and calculates distance. As described above, since the points are replaced with deviation values, when the distances are equal, it is considered that the preferences are the same regardless of the degree of preference. That is, in this case, the closeness of preference for certain music data is calculated as 100%. In other words, the control part 43 calculates the difference of each point about the selected user group. Here, regardless of the size of points in the same music piece, users with small point differences have high preference closeness, and users with large differences have low preference closeness.

Then, for the selected user set, the control unit 43 calculates distances for all music data reproduced by each user, sums the distances, and calculates a value converted to 100% as the proximity information 412. .
Note that steps S27 and S28 may be executed after each of steps S22, S24, and S26.

  Thereafter, the portable terminal 21 (first portable terminal) requests proximity information with other users by the operation of the user 11 (first user) (S29). That is, the user 11 operates the mobile terminal 21 to search for a user whose preference is similar to that of the user 11.

  FIG. 5 is an example of an initial screen of the user search screen 51 according to the first embodiment of the present invention. The user search screen 51 indicates that the identity image 511 of the user 11 is displayed on the screen, and the images of other users are not displayed. When the mobile terminal 21 detects that the user 11 has pressed the update button 512, the mobile terminal 21 transmits a search request for another user whose preference is similar to the server 40. That is, the proximity information is requested. The proximity information may be requested by the mobile terminals 22 to 2n.

  And the server 40 receives the request | requirement of the proximity information with another user from the portable terminal 21, and extracts the proximity information 412 on the basis of the user 11. That is, the control unit 43 reads out the proximity information 412 of each user paired with the user 11 from the storage unit 41, and returns the information to the requesting mobile terminal 21 (S30). At this time, the control unit 43 may transmit the icon image corresponding to the user who is the transmission target of the proximity information 412 and the like.

  Here, in the present embodiment, it is assumed that not only music data preferences are close, but also those who are close to the current position of each user (mobile terminal) are recommended. The reason for this is to search for a user who is more similar to his / her music preference from a plurality of users who have portable terminals in a predetermined space such as a concert venue, and to support the actual meeting. is there.

  Therefore, when extracting the proximity information 412 described above, the control unit 43 desirably narrows down to users whose differences in the current position information 204 associated with each user are within a predetermined range. In this case, the mobile terminal (second mobile terminal) within a physical distance set in advance is narrowed down (specified) based on the current position information of the requesting mobile terminal. For example, it narrows down to the user who has the portable terminal currently located within 500 m from the positional information on the portable terminal 21. Thereby, for example, the transmission process of the proximity information with the user far from the current position of the mobile terminal 21 can be omitted, and the transmission data amount can be reduced. In this case, it is desirable that the server 40 collects the latest current position information from each portable terminal after receiving in step S29. Thereby, it is possible to improve the accuracy of narrowing down users who are physically close to each other.

  In addition, when step S28 is executed after step S29, the calculation processing amount of the proximity information 412 can be reduced by narrowing down to users located within a predetermined range in advance.

  Thereafter, the mobile terminal 21 receives the proximity information with the other users from the server 40, and based on the received proximity information, the user 11 in the mobile terminal 21 and the other users 12 to 2 in the other mobile terminals 22 to 2n. The closeness of preference regarding the music data with 1n is displayed on the screen (S31). For example, the mobile terminal 21 arranges a user icon or the like having a higher degree of proximity relatively closer to its own icon or the like, and places a user icon or the like of a lower degree of approximation relatively far from its own icon or the like. Arrange and display on the screen 216.

  FIG. 6 is an example of a user search result screen 51A according to the first embodiment of the present invention. The user search result screen 51 </ b> A indicates that the concentric high-concentration users are arranged closer to the person image 511 and displayed. For example, the approximate user 514 and the approximate user 514 indicate that the approximate user 514 has higher closeness to the user 11.

  As described above, in the user search function according to the present embodiment, the proximity information 412 between users is calculated using the playback position information 2034 in the music data playback history. Therefore, the point that a portable terminal moves with a user is considered. In other words, where the specific music data is reproduced is taken into account as part of the user's preference. Since it can be said that the place where the user reproduces the music data represents the user's preference, the degree of approximation of the preference including these is calculated, thereby improving the accuracy of searching for a user with a similar preference compared to the conventional one. Can be improved. Therefore, after that, even when the user 11 makes contact using the above-described friend application function as appropriate based on the arrangement of the users displayed on the user search result screen 51A, the users 11 have similar preferences. Therefore, it can be expected that further exchanges will be promoted. That is, communication including face-to-face can be supported.

<Embodiment 2>
In the second embodiment of the present invention, improvements are made to the first embodiment described above, and for the user displayed as the user search result, information on the album to which the music data that the user likes belongs is displayed. Here, the closeness information described above represents the closeness of the preference for the same song, and therefore, according to the display such as the user search result screen 51A expressing the closeness of the preference with the distance based on the closeness information. It can be said that at least the taste for music is close.

  On the other hand, even if the users have similar preferences, music data having a reproduction history on the mobile terminal does not completely match. For example, other users who have similar tastes often listen to (play) music that is unknown to a user or that has been anxious for some time but has not been played on a mobile terminal. In some cases.

  Therefore, in the second embodiment of the present invention, album information of artists often listened to by users whose preferences are similar based on the proximity information is displayed. Thereby, the tendency of the user's preference can be roughly grasped. The user who has performed the user search can recognize the interest of other music or artist that the user who has a similar preference to the user is interested in, and can recognize his / her potential preference. In addition, since it is possible to determine whether or not the potential preference of the user approximates, it is possible to contact a more appropriate user. On the other hand, for each user displayed as a user search result, it may be tempting to disclose the top several songs based on their playback history as they are. This is also a reasonable disclosure level from the viewpoint of privacy. For example, in a live venue where multiple artists appear, each spectator may not have listened to the songs of all the performing artists. However, according to the second embodiment of the present invention, by knowing that a user who has a preference similar to that of a specific artist is also interested in other artists, he / she is interested in the artist and the user. Can do.

  Therefore, the present embodiment has the following configuration. That is, it is assumed that the server 40 according to the present embodiment holds a plurality of album information, which is a music data set to which a plurality of music data belongs, in the storage unit 41. Here, the album information includes, for example, an album name, an artist name, a music list, an album image (jacket image), and the like.

  And the portable terminal 21 concerning this Embodiment is the state where the user search result screen 51A mentioned above is displayed, for example, when the designation | designated of the user 12 (2nd user) is received from the user 11, the user 12 Displays a screen that displays profile information about. Here, it is assumed that album information including music data that is often played by the designated user is displayed on the profile screen.

  The operation at this time is as follows. First, the portable terminal 21 requests | requires the display information (profile information) regarding the user 12 with respect to the server 40, when specification of the user 12 is received among the other users 12-1n displayed on the user search result screen 51A. . Then, the server 40 specifies the music data set (album information) to which the requested music data of the user 12 belongs based on the preference information 411. At this time, the server 40 may specify the top several songs of music data having a large number of playbacks from the playback history of the user 12 and specify, for example, the top predetermined number of album information to which each music data belongs. Thereafter, the server 40 transmits the album image of the specified album information to the portable terminal 21. Then, the mobile terminal 21 includes the received album image in the display information related to the user 12 and displays it on the screen 216.

  FIG. 7 shows an example of a search user profile display screen 52 according to the second exemplary embodiment of the present invention. The profile display screen 52 includes a user image 521, album images 5221 to 5223, and a profile field 523. Here, it is assumed that the album images 5221 to 5223 are jacket images or the like of albums to which any of the top several songs having the highest number of reproductions of the reproduction history of the user 12 belongs.

  In the above description, the server 40 may specify album information that does not include songs that are highly preferred by the user 11 that is the request source, when specifying album information that the user 12 often listens to. As a result, the requesting user 11 can efficiently recognize his / her potential preferences.

<Embodiment 3>
In the third embodiment of the present invention, improvements are made to the above-described first or second embodiment, and icons of other users on the screen are changed according to changes in the orientation and inclination of the mobile terminal displaying the user search result screen. The screen is updated in conjunction with the arrangement of the screens.

  Therefore, each of the mobile terminals 21 to 2n according to the present embodiment can acquire altitude information indicating altitude in addition to the current (two-dimensional) position information. Here, the altitude information is, for example, a value indicating the altitude calculated from the atmospheric pressure information. Each of the mobile terminals 21 to 2n includes a geomagnetic sensor and an acceleration sensor. As a result, it is possible to detect a change in azimuth or inclination in which the tip of the terminal faces.

  And each of the portable terminals 21-2n shall transmit altitude information (or atmospheric pressure information itself) with the current position information to the server 40. In response to this, the server 40 stores the current position information and altitude information received from each mobile terminal in the storage unit 41 in association with each other. Moreover, the server 40 returns the current position information and altitude information of other mobile terminals in response to a request from an arbitrary mobile terminal that displays the user search result screen, for example. That is, an arbitrary mobile terminal acquires the current position information and altitude information in another mobile terminal from the server 40.

  And whenever the said portable terminal detects the change of the present position information and the said height information in the said portable terminal, based on the present position information and the height information in each of the said portable terminal and another portable terminal, the said portable terminal The difference in distance and altitude from other mobile terminals based on is calculated. And the said portable terminal updates the display of a screen according to the difference of the computed distance and altitude.

  FIG. 8 is a flowchart for explaining the flow of the user display position update process according to the third embodiment of the present invention. As a premise, as described above, each mobile terminal has already transmitted the current position information and altitude information to the server 40. Further, the server 40 stores the current position information and altitude information received from each mobile terminal in the storage unit 41 in association with each mobile terminal. Similarly to the first embodiment, it is assumed that preference information for each user and music data and proximity information between users have been calculated.

  Therefore, the portable terminal 21 on which the user search result screen 51A has been displayed acquires the current position information and altitude information of other portable terminals from the server 40 (S41). For example, at the timing when the update button 512 in the user search result screen 51A is pressed by the operation of the user 11, the server 40 is requested for the latest position information and altitude information of other portable terminals. Moreover, the portable terminal 21 may request the latest proximity information at this timing. Or the portable terminal 21 may request | require the newest location information and altitude information of another portable terminal regularly.

  Moreover, the portable terminal 21 acquires the current position information and altitude information, the posture, and the orientation of the terminal (S42). The portable terminal 21 may acquire the latest position information and altitude information at the same timing as step S41. Or you may update the newest position information and altitude information of a self-portable terminal regularly. Further, when the geomagnetic sensor and the acceleration sensor detect a change in the direction or inclination of the mobile terminal 21, the mobile terminal 21 acquires the direction or inclination from the geomagnetic sensor and the acceleration sensor. And the portable terminal 21 calculates the attitude | position and direction (direction) of the said terminal from the information acquired from the geomagnetic sensor and the acceleration sensor.

  Subsequently, the mobile terminal 21 determines whether or not the calculated inclination is within 30 degrees (S43). If it is determined in step S43 that the inclination is within 30 degrees (or parallel to the ground), the mobile terminal 21 specifies the direction of the other terminal with reference to its own terminal, and the distance to the other terminal Is calculated (S44). The direction in which another mobile terminal exists around the current position of the mobile terminal 21 is classified into, for example, any one of eight directions (east, west, north, northeast, northwest, southeast, and southwest). And when the principal image 511 is displayed on the lower side of the screen as in the user search result screen 51A, another mobile terminal existing in the direction in the upper direction of the screen is specified. And the difference of the positional information of the specified portable terminal and the portable terminal 21 is calculated as a distance.

  And the portable terminal 21 draws the other terminal in the direction of the front-end | tip of an own terminal on a plane (S45). That is, the icon of the user of the mobile terminal existing in the specified direction is displayed on the screen according to the calculated distance. For example, if the mobile terminal 21 is facing north, only the user located on the north side is displayed. That is, as usual, a user's icon etc. are arrange | positioned on a plane without considering the difference in altitude.

  On the other hand, when it is determined in step S43 that the inclination is greater than 30 degrees, the mobile terminal 21 calculates a difference in altitude between its own terminal and another terminal (S46). That is, the portable terminal 21 calculates the altitude from the atmospheric pressure information of the other portable terminals acquired in step S41. And the difference with the altitude of the portable terminal 21 is calculated.

  Subsequently, the mobile terminal 21 specifies the direction of the other terminal with reference to its own terminal, and calculates the distance from the other terminal (S47). That is, it is calculated in the same manner as in step S44. And the portable terminal 21 draws the other terminal in the direction of the front-end | tip of an own terminal three-dimensionally (S48). For example, it is assumed that the direction of the mobile terminal 21 is north and the altitude is calculated as 10 m. In this case, the user of the mobile terminal located on the north side when viewed from the mobile terminal 21 is specified as the display target. When the altitude of the user to be displayed is 15 m or higher, the upper level is displayed on the stereoscopic display, the same level is displayed between 10 m and 14.99 m, and the lower level is displayed when the height is 9.99 m or lower. The mobile terminal 21 displays it three-dimensionally on the screen. That is, in consideration of the difference in altitude, user icons and the like are arranged three-dimensionally.

  As described above, according to the present embodiment, when the user changes the direction or inclination of the mobile terminal in a state where the user search result screen is displayed on the screen, the icons of other displayed users are displayed accordingly. The arrangement is updated. That is, the relative positions of neighboring terminals (users) are displayed relatively on the screen with reference to their own terminals.

  In particular, when the direction of the tip of the mobile terminal changes significantly, the icon of the user that has been displayed until then is hidden, and conversely, the icon of the user that has been hidden until then is displayed. . Thereby, for example, when the user search result is displayed at a place such as an outdoor concert, it is possible to grasp in real time whether there is a user whose preference is similar to the user in which direction.

  Furthermore, when the inclination of the mobile terminal becomes equal to or greater than a predetermined angle, the mobile terminal is updated as in 3D display. Thereby, it is possible to grasp in real time whether or not there is a user whose preference is similar to that of a seat on a different floor (for example, an arena seat at a concert venue).

  In these cases, it becomes easier to grasp the positional relationship of other users by superimposing the drawing data in the corresponding area or building.

  As altitude information, the MAC address of the wireless access point may be used in addition to the atmospheric pressure information described above. The server 40 can specify the altitude of the mobile terminal by referring to the DB of the MAC address and latitude / longitude information separately.

<Embodiment 4>
The fourth embodiment of the present invention is an improved example of the first to third embodiments described above. In the fourth embodiment of the present invention, an inter-terminal message communication function will be described. As a premise, first, the user 11 makes a friend application to an arbitrary user (for example, the user 12) based on the user search result screen 51A and the profile display screen 52. Thereafter, when the friend application is approved by the user 12, the user 11 and the user 12 can thereafter perform inter-terminal message communication via the system.

  Here, in the inter-terminal message communication function according to the present embodiment, an arbitrary mobile terminal receives a plurality of message information to which display deadlines are added from any of the other mobile terminals in different time zones. And when the portable terminal displays a message display screen that displays a plurality of received message information in chronological order, the message information to be displayed, which has passed the display deadline added to each message information, is displayed. The specified message information is excluded from the display target thereafter. Note that the inter-terminal message communication function according to the present embodiment can be applied not only between two terminals but also within a designated terminal group of three or more terminals. Further, it is assumed that the display time limit can be set on the server 40 or each portable terminal.

  Normally, message information transmitted and received between terminals is not only held on the server side but also held in both terminals (applications) that perform message communication, but is not disclosed to terminals other than the terminal. . Here, it is possible to delete past messages stored on the terminal of the user, but it is possible to delete at the discretion of the user. I can't.

  For example, suppose that there was a user who had been estranged from a certain time, although various messages were exchanged because it was intimate. If past message information or the like is left on the user's mobile terminal, there is a risk that it may be misused without being abused or malicious.

  Therefore, in the present embodiment, a message after the expiration of the display deadline is not displayed. Thereby, security improvement and privacy protection can be ensured.

  Furthermore, in the present embodiment, in the inter-terminal message communication function, predetermined image data is transmitted instead of or added to the message information and displayed on the message display screen of the receiving destination. . For example, it is possible to communicate between users using an image with an artist as a motif. Thereby, it is possible to support smoother communication between users who have similar musical tastes than to convey in text.

  FIG. 9 is an example of the inter-terminal message transmission screen 53 displayed on the mobile terminal operated by the user A according to the fourth embodiment of the present invention. The terminal-to-terminal message transmission screen 53 shows a state where the selected transmission candidate sticker image 533 is selected from the transmission candidate sticker image group 532 and displayed as the transmission target sticker image 531 by the operation of the user A. Then, by transmitting, the transmission target sticker image 531 is transmitted to the portable terminal possessed by the user B instead of the message information or together with the message information.

  FIG. 10 is an example of the inter-terminal message display screen 54 displayed on the mobile terminal operated by the user B according to the fourth embodiment of the present invention. The inter-terminal message display screen 54 displays display messages MSG1, MSG2 and a display sticker image STC1. Here, the display deadline is 30 days after reception. Since the display message MSG1 is sent 29 days ago from the mobile terminal of the user A, it is displayed on the inter-terminal message display screen 54 of the mobile terminal of the user B at this point. On the other hand, since the non-display message MSG0 is transmitted from the mobile terminal of the user A 30 days or more ago, the non-display message MSG0 is excluded from display on the inter-terminal message display screen 54 of the mobile terminal of the user B and is not displayed. It shows that. Further, in FIG. 9, the display sticker image STC <b> 1 indicates that the transmission target sticker image 531 transmitted from the mobile terminal of the user A is displayed on the inter-terminal message display screen 54 of the mobile terminal of the user B.

<Embodiment 5>
The fifth embodiment of the present invention is an improved example of the first to fourth embodiments described above. In the fifth embodiment, the server 40 holds electronic coupon information in which a predetermined condition is set, and a third condition that satisfies a predetermined condition from among a plurality of portable terminals based on the calculated preference information 411. And the electronic coupon information is transmitted to the selected third portable terminal. The third portable terminal displays the received electronic coupon information on the screen.

  FIG. 11 is an example of an electronic coupon display screen 55 according to the fifth exemplary embodiment of the present invention. On the electronic coupon display screen 55, electronic coupons 551 to 554 are displayed. The electronic coupon 551 is an electronic coupon in which a limited item of the artist can be obtained free of charge by the first ten visitors of each venue of a certain artist's live tour. In this case, for example, it is assumed that the preference information for a plurality of music data of a specific artist is set on condition that the preference information is a predetermined value or more. Then, the server 40 refers to the storage unit 41, selects a mobile terminal that satisfies the conditions of the electronic coupon 551 based on the reproduction history of the music data of the specific artist and the calculated preference information 411, and sends the electronic data to the mobile terminal. Coupon 551 is transmitted.

  In addition, even if it is the same artist set to the conditions of the electronic coupon 551, when the tendency of preference information differs, you may define another electronic coupon which presents a different item. In other words, an appropriate electronic coupon corresponding to the preference information can be distributed to each user.

  Also, the electronic coupon 552 is an electronic coupon that provides a free drink with a drink only for a fan party of a certain artist group. In this case, for example, it is set as a condition that the group is a group of users who are friends due to high closeness information by music data of a specific artist group. And the server 40 refers to the memory | storage part 41, selects the portable terminal group which satisfy | fills the conditions of the electronic coupon 552 based on proximity information, a friend's registration, and present position information, and sends an electronic coupon to each of the said portable terminal group. 552 is transmitted. As a result, the group generated through this system can be guided to the off-line meeting.

  Also, the electronic coupon 553 is an electronic coupon that turns off official goods 50% off for a specific album purchaser of an artist. In this case, for example, it is set as a condition that a history of reproduction of a plurality of music data belonging to a specific artist's album is provided. And the server 40 refers to the memory | storage part 41, selects the portable terminal which satisfy | fills the conditions of the electronic coupon 553 based on a reproduction | regeneration log | history and a purchase history, and transmits the electronic coupon 553 to the said portable terminal. Thereby, an effective electronic coupon according to the reproduction history can be distributed.

  Also, the electronic coupon 554 is an electronic coupon that reduces the food and beverage bill at a certain store by 30% for fans of a certain artist group. In this case, for example, it is assumed that the preference information is set to be a predetermined value or more for a plurality of music data of a specific artist group. Then, the server 40 refers to the storage unit 41, selects a portable terminal that satisfies the conditions of the electronic coupon 554 based on the reproduction history of the music data of the specific artist group and the calculated preference information 411, and sends the portable terminal to the portable terminal. An electronic coupon 554 is transmitted.

  The conditions set for the electronic coupon can be freely set for the server 40 from the store side. Further, based on the reproduction position information 2034 and the last reproduction date and time 2032 held by the server 40, it is possible to identify a user who often stays in a specific time zone in a trade area of a specific store. Or you may set as a condition the case where the current position information of each terminal is the trade area of a specific store. In addition, there are times when there are few visitors, such as off-season and weekday evening. Therefore, the electronic coupon can be distributed by matching the time zone where the seat has room on the store side with the place and time zone where the user stays. Furthermore, you may enable it to set arbitrarily the delivery timing of an electronic coupon immediately before, 3 days ago, 1 week ago, etc. at the store side.

  In addition, a QR code (registered trademark) may be added to the electronic coupon and associated with the terminal. Thereby, the frequency | count of use and a user of an electronic coupon can be grasped | ascertained and controlled. In addition, the kind and conditions of an electronic coupon are not limited to these.
