[0030] The operation button 11 is used to perform various input operations such as various selections and various decisions. The acceleration sensor 12 is a sensor that detects acceleration occurring in the first communication terminal 2 when the first user shakes the first communication terminal 2, etc. Preferably, the acceleration sensor 12 is a three-axis sensor that detects acceleration in each of three axial directions.

[0031] It should be noted that FIG. 2 only shows a part of the main hardware configuration of the first communication terminal 2, and the first communication terminal 2 may include other configurations that are generally included in a computer.

[0032] <Server hardware configuration> FIG. 3 is a block diagram schematically illustrating an example of a hardware configuration of the server device 4 shown in FIG. As shown in FIG. 3, the server device 4 includes a storage device 13, a control device 14, and a communication device 15 as main components.

[0033] The storage device 13 is an auxiliary storage device configured by a hard disk or the like arranged inside the server device 4. The storage device 13 stores various programs, various information, and information on the processing results required for the execution of processing in the control device 14.

[0034] The control device 14 mainly includes a CPU 14A and a memory (main storage device) 14B. The CPU 14A controls the operation of various components of the server device 4. The memory 14B stores, for example, various programs and the like required for executing processes in the control device 14.

[0035] Furthermore, the control device 14 functions as various functional components by the CPU 14A executing predetermined programs stored in the storage device 13 or memory 14B, etc. Details of these functional components will be described later. The programs may be stored in the storage device 13, or may be stored in an external storage device (not shown) of the server device 4, etc.

[0036] The communication device 15 is configured with a communication interface and the like for communicating with external devices. This communication refers to network communication such as the Internet. The communication device 15 transmits and receives various information between the first communication terminal 2 and the second communication terminal 3, for example.

[0037] The server device 4 can be realized using an information processing device such as a dedicated or general-purpose server computer. The server device 4 may be configured from a single information processing device or from multiple information processing devices distributed over a communication network NT. Fig. 3 shows only a portion of the main hardware configuration of the server device 4, and the server device 4 may also have other components that are generally included in a computer.

[0038] <Functional configuration of communication terminal> Fig. 4 is a block diagram schematically showing an example of the functional configuration of the first communication terminal 2 shown in Fig. 1. Although not shown, the functional configuration of the second communication terminal 3 (and other communication terminals not shown) is also similar to that of the first communication terminal 2.

[0039] As shown in Figure 4, the first communication terminal 2 includes a terminal memory unit 20, a direct communication unit 22, a terminal network communication unit 23, an acceleration acquisition unit 24, an acceleration determination unit 25, a timing signal generation unit 26, a timing determination unit 27, a time measurement unit 28, an application signal generation unit 29, an operation reception unit 30, an audio reception unit 31, a display control unit 32, a game execution unit 33, an audio output unit 34, a presentation unit 35, a counting unit 36, and a schedule execution unit 37.

[0040] Of these, the terminal storage unit 20 is realized by the storage device 5. The other functional components are realized by the control device 6 executing programs stored in the storage device 5 or the like.

[0041] The terminal storage unit 20 stores user information 20A, friend information 20B, effect information 20C, and game information 20D.

[0042] The user information 20A is information relating to the first communication terminal 2, and includes identification information 21A, image information 21B, audio information 21C, schedule information 21D, and integrated value information 21E.

[0043] The friend information 20B is information relating to the second communication terminal 3 and other communication terminals, and includes identification information 21G, image information 21H, and audio information 21I associated with each communication terminal. The number of entries in this friend information 20B indicates the number of registered friends.

[0044] The identification information 21A is information for identifying (specifying) the communication terminal, and may be, for example, a unique identification number assigned at the time of manufacture.

[0045] The image information 21B includes emoticons or pictograms that represent the mood, physical condition, or schedule of the first user.

[0046] A plurality of pieces of image information 21B are stored in advance in the terminal storage unit 20. Furthermore, as will be described later, the terminal storage unit 20 stores image information selected by the image selection unit 45 of the server device 4 and transmitted from the server network communication unit 41 as image information 21B.

[0047] Furthermore, the image information 21B may be purchased and acquired in advance by the guardian of the first user in the younger age group using a communication terminal such as a smartphone (not shown) that the guardian owns, and the image information 21B may then be sent directly to the first communication terminal 2 via wireless communication or the like, and stored in the terminal memory unit 20 of the first communication terminal 2.

[0048] The voice information 21C includes recorded data of the voice of the first user, etc. The voice information 21C is stored in the terminal storage unit 20 every time the voice of the first user is received.

[0049] The schedule information 21D includes a date and image information 21B linked to the date by the selection operation of the first user.

[0050] The integrated value information 21E is a value (integrated value) integrated by a counting unit 36, which will be described later.

[0051] The identification information 21G is information for identifying (specifying) the communication terminal. This may be, for example, a unique identification number assigned at the time of manufacturing. Every time the first communication terminal 2 performs direct wireless communication with a new communication terminal, the identification information 21G of the new communication terminal is stored in the terminal storage unit 20.

[0052] The image information 21H is image information received from the second communication terminal 3 and other communication terminals via network communication. The image information 21H is stored in association with the identification information 21G of the second communication terminal 3 and other communication terminals.

[0053] The voice information 21I includes recorded data such as the voice of the second user of the second communication terminal 3 and the voice of the user of the other communication terminal, which are received from the second communication terminal 3 and the other communication terminals via network communication. The voice information 21I is stored in association with the identification information 21G of the second communication terminal 3 and the other communication terminals.

[0054] The rendering information 20C is information including rendering (video and / or sound effects) selected by the rendering unit 35, which will be described later. The terminal storage unit 20 stores a plurality of pieces of rendering information 20C.

[0055] The game information 20D includes a game program, play data indicating the game progress status of the game program and player information, and the like.

[0056] The information described above as being stored in the terminal storage unit 20 may be stored in a server storage unit 40 of the server device 4 (described later) instead of the terminal storage unit 20. Alternatively, the information may be stored in both the terminal storage unit 20 and the server storage unit 40.

[0057] The direct communication unit 22 transmits and receives identification information 21A, 21G to and from the second communication terminal 3 and other communication terminals (hereinafter, other communication terminals will be omitted as necessary) by performing direct wireless communication with them. That is, the direct communication unit 22 transmits identification information 21A of the first communication terminal 2 itself and receives identification information 21G of the second communication terminal 3. The received identification information 21G is stored as friend information 20B.

[0058] However, the direct communication unit 22 transmits the identification information 21A to the second communication terminal 3 when the determination result of the acceleration determination unit 25, which will be described later, is a positive determination.

[0059] Then, if the first communication terminal 2 and the second communication terminal 3 are within a range where direct wireless communication is possible, the direct communication unit 22 may perform direct wireless communication even if the determination result of the acceleration determination unit 25 described below is negative. In this case, however, the identification information 21A is not transmitted to the second communication terminal 3. Of course, the same applies to the case from the second communication terminal 3 to the first communication terminal 2.

[0060] In other words, even if the first communication terminal 2 and the second communication terminal 3 are within a range where they can directly communicate with each other and perform direct wireless communication, if the judgment result of the acceleration judgment unit 25 described later is a negative judgment, they will not send or receive each other's identification information 21A, 21G.

[0061] More specifically, when the determination result of acceleration determination unit 25 (described later) is a positive determination and the determination result of timing determination unit 27 (described later) is a positive determination, direct communication unit 22 transmits identification information 21A to second communication terminal 3. Furthermore, even if the determination result of acceleration determination unit 25 is a positive determination, when the determination result of timing determination unit 27 (described later) is a negative determination, direct communication unit 22 performs direct wireless communication but does not transmit identification information 21A to second communication terminal 3.

[0062] That is, even if the first communication terminal 2 and the second communication terminal 3 are within a range where they can directly communicate wirelessly with each other and the judgment result of the acceleration judgment unit 25 described later is a positive judgment, if the judgment result of the timing judgment unit 27 described later is a negative judgment, they will not send or receive each other's identification information 21A, 21G.

[0063] Furthermore, even if the judgment result of the acceleration judgment unit (not shown) and timing judgment unit (not shown) of the second communication terminal 3 described later is a positive judgment and identification information 21G is transmitted from the second communication terminal 3, if the judgment result of the acceleration judgment unit 25 or timing judgment unit 27 of the first communication terminal 2 described later is a negative judgment, the direct communication unit 22 of the first communication terminal 2 will not receive the identification information 21G.

[0064] The terminal network communication unit 23 is capable of performing network communication (e.g., Internet communication via Wi-Fi) with the second communication terminal 3 that has sent and received each other's identification information 21A, 21G through direct wireless communication by the direct communication unit 22, and transmits image information 21B received by the operation reception unit 30 described later to the second communication terminal 3, and receives image information 21H from the second communication terminal 3.

[0065] More specifically, when the first communication terminal 2 and the second communication terminal 3 transmit and receive each other's identification information 21A, 21G via the direct communication unit 22, the terminal network communication unit 23 transmits an application signal to a server network communication unit 41 of the server device 4, which will be described later, via network communication. Thereafter, the terminal network communication unit 23 receives a permission signal transmitted from the server network communication unit 41 (the first communication terminal 2 is permitted to communicate via network from the server device 4), thereby enabling network communication with the second communication terminal 3.

[0066] The first communication terminal 2 can transmit one or more pieces of image information 21B, which are received by an operation receiving unit 30 (described later) when the first user operates the operation button 11, to the second communication terminal 3 (having the identification information 21G received by the direct communication unit 22) by performing network communication with the terminal network communication unit 23. Furthermore, the first communication terminal 2 can also transmit and receive audio information 21C to and from the second communication terminal 3 through the network communication.

[0067] Furthermore, the first communication terminal 2 cannot perform network communication via the terminal network communication unit 23 with a communication terminal with which the first communication terminal 2 has not transmitted and received mutual identification information.

[0068] The acceleration acquisition unit 24 acquires the acceleration detected by the acceleration sensor 12. When the acceleration sensor 12 is a three-axis sensor, the value and direction of the acceleration detected by the acceleration sensor 12 are acquired.

[0069] The acceleration determination unit 25 determines whether the acceleration received by the acceleration acquisition unit 24 is equal to or greater than a predetermined value. When the acceleration sensor 12 is a triaxial sensor, it may be configured to determine whether the accelerations in all of one or more predetermined directions are equal to or greater than a predetermined value.

[0070] The timing signal generating unit 26 generates a timing signal when the determination result of the acceleration determining unit 25 is a positive determination. The generated timing signal is transmitted from the direct communication unit 22 to the second communication terminal 3.

[0071] The second communication terminal 3 also transmits a timing signal to the first communication terminal 2 through the same process as described above. The direct communication unit 22 then receives this timing signal.

[0072] The timing determination unit 27 determines the timing of transmission and reception of the timing signal by the direct communication unit 22 .

[0073] More specifically, timing determination unit 27 determines whether the difference between the timing at which direct communication unit 22 transmits a timing signal and the timing at which direct communication unit 22 receives the timing signal from second communication terminal 3 is within a predetermined time. If the determination result of timing determination unit 27 is a positive determination, direct communication unit 22 transmits identification information 21A of first communication terminal 2 itself to second communication terminal 3.

[0074] The second communication terminal 3 also performs a similar process to transmit the identification information of the second communication terminal 3 to the first communication terminal 2, and the direct communication unit 22 receives this information (not shown). The received identification information is stored in the terminal storage unit 20 as identification information 21G.

[0075] In other words, if the judgment results of the acceleration judgment unit 25 and the timing judgment unit 27 are both positive judgments, the first communication terminal 2 first transmits identification information 21A to the second communication terminal 3 via direct wireless communication by the direct communication unit 22. At the same time, the second communication terminal 3 also transmits the identification information 21G to the first communication terminal 2 through the same process. The first communication terminal 2 that has received the identification information 21G transmits an application signal from the terminal network communication unit 23 to a server network communication unit 41 of the server device 4, which will be described later, by network communication. At the same time, the second communication terminal 3 also transmits an application signal to the server network communication unit 41 through the same process. Thereafter, when the terminal network communication unit 23 receives the permission signal sent from the server network communication unit 41 of the server device 4, and the second communication terminal 3 similarly receives the permission signal, the first communication terminal 2 and the second communication terminal 3 are able to perform network communication.

[0076] The time measurement unit 28 measures the time (length of time) during which the determination result by the acceleration determination unit 25 is a positive determination, that is, the time measurement unit 28 measures the time (length of time) during which the acceleration is equal to or greater than a predetermined value.

[0077] The application signal generating unit 29 generates an application signal. The application signal includes the identification information 21G of the second communication terminal 3 received by the direct communication unit 22.

[0078] The operation acceptance unit 30 accepts information input by the first user by operating the operation button 11. For example, it accepts a selection operation for selecting at least one piece of image information 21B from the plurality of pieces of image information 21B stored in the device storage unit 20. The operation acceptance unit 30 also accepts various other selection operations by the first user (this will be described later).

[0079] The voice receiving unit 31 receives the voice of the first user as voice information 21C using the microphone 9. The voice information 21C is stored in the terminal storage unit 20.

[0080] The display control unit 32 displays various screens on the display 8 based on the information received by the operation reception unit 30.

[0081] Furthermore, the display control unit 32 displays a rendering screen included in the rendering information 20C selected by the rendering unit 35, which will be described later.

[0082] The display control unit 32 also displays the image information 21H received from the second communication terminal 3 via the terminal network communication unit 23. Furthermore, the display control unit 32 can simultaneously display (arrange on one screen) multiple pieces of received image information. For example, when multiple pieces of image information 21H are sent from the second communication terminal 3, they can be simultaneously displayed.

[0083] The display control unit 32 can also display various information received from the terminal network communication unit 23. The various information here includes, for example, the weather, temperature, and recommended fashion for the day.

[0084] Furthermore, the display control unit 32 can display on the display 8 a calendar executed by a schedule execution unit 37, which will be described later.

[0085] Furthermore, the display control unit 32 can display the integrated value information 21E.

[0086] Furthermore, the display control unit 32 can display a game executed by a game execution unit 33, which will be described later.

[0087] The game execution unit 33 executes a game using the game information 20D stored in the device storage unit 20. The game is executed based on one or more pieces of information such as a selection operation received by the operation reception unit 30, acceleration acquired by the acceleration acquisition unit 24, and audio information received by the audio reception unit 31. The content of the game may be, for example, a quest to defeat an enemy character such as a dragon.

[0088] In addition, the above game allows the first communication terminal 2 and the second communication terminal 3 to cooperate and play cooperatively by directly communicating wirelessly with each other. Furthermore, it is also possible for three or more communication terminals, including those other than the second communication terminal 3, to simultaneously communicate wirelessly with each other and cooperate and play cooperatively.

[0089] The audio output unit 34 outputs audio information 21I received from the second communication terminal 3 and stored as friend information 20B in the terminal storage unit 20, based on the selection operation accepted by the operation acceptance unit 30. By outputting audio in addition to image information, smooth communication with the second user of the second communication terminal 3 can be achieved.

[0090] Furthermore, the audio output unit 34 outputs sound effects included in the production information 20C selected by the production unit 35, which will be described later.

[0091] Furthermore, the audio output unit 34 outputs sounds in accordance with the displays made by the display control unit 32.

[0092] When network communication with the second communication terminal 3 is enabled by the terminal network communication unit 23, the production unit 35 selects one of the multiple pieces of production information 20C stored in the terminal storage unit 20 (i.e., sets a production) based on the acceleration detected by the acceleration determination unit 25. Of the production information 20C selected by the production unit 35, the display control unit 32 displays the production screen, and the audio output unit 34 outputs the sound effects.

[0093] For example, if the predetermined acceleration value in the acceleration determination unit 25 is 0.1 km / s 2 Then, the production unit 35 will calculate the acceleration as 0.1 km / s 2 More than 0.3km / s 2 When the speed is less than 0.3km / s 2 More than 0.5km / s 2 When the speed is less than 0.5km / s 2 In the above cases, different rendering information 20C may be selected.

[0094] Alternatively, when network communication with the second communication terminal 3 becomes possible via the terminal network communication unit 23, the performance unit 35 may select one of the multiple performance information 20C stored in the terminal memory unit 20 based on the length of time measured by the time measurement unit 28 described above.

[0095] For example, different performance information 20C may be selected for the case where the length of the time is less than 1 second, 1 second or more but less than 5 seconds, 5 seconds or more but less than 10 seconds, and 10 seconds or more.

[0096] Alternatively, when network communication with the second communication terminal 3 becomes possible via the terminal network communication unit 23, the performance unit 35 may select one of the multiple performance information 20C stored in the terminal memory unit 20 based on a combination of the acceleration detected by the acceleration determination unit 25 and the length of time measured by the time measurement unit 28.

[0097] Furthermore, even when network communication with the second communication terminal 3 is possible via the terminal network communication unit 23, the rendering unit 35 may select rendering information 20C based on, for example, various selection operations received from the first user by the operation reception unit 30. In this case, rendering information 20C may be selected based on the integrated value information 21E. For example, the higher the value of the integrated value information 21E, the more rendering information 21 that is set to emit light of various colors or to emit intense sound effects may be selected.

[0098] The counting unit 36 ​​adds up the integrated value when the direct communication unit 22 performs direct wireless communication with the second communication terminal 3 or another communication terminal.

[0099] The integrated value is stored in the terminal storage unit 20 as integrated value information 21E, and can be displayed by the display control unit 32 in response to a selection operation or the like on the operation reception unit 30. This counts the number of times the first user carrying the first communication terminal 2 has passed by users carrying the second communication terminal 3 or other communication terminals (the number of times they were within a range where direct wireless communication was possible).

[0100] The schedule execution unit 37 first executes the calendar function, and the calendar is displayed on the display 8 by the display control unit 32.

[0101] Furthermore, when image information 21B is selected by an operation accepted by operation accepting unit 30 while a calendar is being displayed on display 8 by display control unit 32, schedule executing unit 37 associates the date on the calendar with image information 21B. The associated date and image information 21B are stored in terminal storage unit 20 as schedule information 21D. Note that schedule executing unit 37 reflects schedule information 21D when display control unit 32 displays a calendar.

[0102] Furthermore, when the date associated with image information 21B in schedule information 21D arrives, terminal network communication unit 23 transmits image information 21B associated with that date in schedule information 21D to second communication terminal 3 that has become capable of network communication. This makes it possible to convey the schedule of the first user of first communication terminal 2 for that day, etc. to the second user of second communication terminal 3.

[0103] Conversely, when the terminal network communication unit 23 receives image information 21H linked to the date of the schedule information in the second communication terminal 3, the display control unit 32 displays the image information based on the selection operation of the operation reception unit 30. That is, the display control unit 32 displays the schedule information (not shown) received from the second communication terminal 3 based on the selection operation of the operation reception unit 30. This allows the first user of the first communication terminal 2 to know the schedule of the second user of the second communication terminal 3.

[0104] In addition, when the first communication terminal 2 receives image information 21H linked to dates in schedule information from the second communication terminal 3 and other communication terminals with which it can communicate over the network, the display control unit 32 can simultaneously display (list display) these multiple pieces of image information 21H.

[0105] <Functional configuration of server device> 1 allows communication terminals that have transmitted and received each other's identification information to communicate with each other through a network. Note that once the server device 4 has permitted network communication between the communication terminals, the communication terminals can thereafter freely communicate with each other through a network.

[0106] FIG. 5 is a block diagram schematically illustrating an example of a functional configuration of the server device 4 shown in FIG. As shown in FIG. 5, the server device 4 includes a server storage unit 40, a server network communication unit 41, an identification information determination unit 42, an enabling signal generation unit 43, an SSID determination unit 44, and an image selection unit 45.

[0107] Of these, the server storage unit 40 is realized by the storage device 13. The other functional components are realized by the control device 14 executing programs stored in the storage device 13 or the like.

[0108] The server storage unit 40 stores identification information 40A, image information 40B, and SSID information 40C. As already explained, the information that has been described as being stored in the terminal storage unit 20 may also be stored in this server storage unit 40.

[0109] The identification information 40A is the identification information of the first communication terminal 2, the second communication terminal 3, and other communication terminals included in the application signal received by the server network communication unit 41. Alternatively, the identification information 40A may be the identification information of each communication terminal stored in advance in the server storage unit 40.

[0110] The image information 40B includes a plurality of pieces of image information other than the image information stored in the terminal storage unit 20 of the first communication terminal 2, the second communication terminal 3, and other communication terminals.

[0111] The SSID information 40C is information (for example, text information) about a predetermined SSID. The SSID information 40C may be of one type or of multiple types.

[0112] The server network communication unit 41 performs network communication with the first communication terminal 2, the second communication terminal 3, and other communication terminals.

[0113] Furthermore, the server network communication unit 41 receives application signals from two communication terminals, such as the first communication terminal 2 and the second communication terminal 3, which have transmitted and received identification information to and from each other.

[0114] Furthermore, the server network communication unit 41 transmits a permission signal generated in a permission signal generation unit 43 (described later) to the terminal network communication units of the two communication terminals, for example, the first communication terminal 2 and the second communication terminal 3. The two communication terminals that have received the permission signal can then perform network communication between each other.

[0115] In addition, the server network communication unit 41 transmits image information 40B selected by the image selection unit 45 described later to the terminal network communication unit 23 of the first communication terminal 2 (or the second communication terminal 3, or any other communication terminal).

[0116] The permission signal generation unit 43 generates a permission signal when the server network communication unit 41 receives an application signal from each of two communication terminals that have transmitted and received identification information to each other, such as the first communication terminal 2 and the second communication terminal 3.

[0117] The SSID determination unit 44 determines whether the SSID used when the direct communication unit 22 of the first communication terminal 2 (or the second communication terminal 3, or any other communication terminal) performed network communication using Wi-Fi is a specified SSID indicated by the SSID information 40C stored in the server memory unit 40.

[0118] When the determination result of the SSID determination unit 44 is a positive determination, the image selection unit 45 selects one or more pieces of image information from the plurality of pieces of image information 40B stored in the server storage unit 40. The selected image information is transmitted from the server network communication unit 41 to the server network communication unit 41. This allows the image to be given as a bonus to the first communication terminal 2 (or the second communication terminal 3, or any other communication terminal) that has performed communication via the Internet using Wi-Fi with a specified SSID.

[0119] Due to the functional configuration of the server device 4 described above, when two communication terminals that have sent an application signal to the server network communication unit 41, for example, the first communication terminal 2 and the second communication terminal 3, receive an authorization signal at their respective terminal network communication units 23, they are able to perform network communication (such as Internet communication via Wi-Fi) with each other via the terminal network communication units 23.

[0120] <Processing by communication system> An example of the process until the first communication terminal 2 and the second communication terminal 3 perform network communication will be described in detail below using the flowchart in Fig. 6. Note that the following steps are an example of the process, and the order and content of the steps can be changed as appropriate.

[0121] (Step SP1) When the first communication terminal 2 and the second communication terminal 3 are within a range where they can communicate directly by wireless, direct wireless communication is performed between the direct communication unit 22 of the first communication terminal 2 and the direct communication unit 22 of the second communication terminal 3. However, at this step, the identification information 21A and 21G are not transmitted or received from each other. Thereafter, the process proceeds to step SP2.

[0122] (Step SP2) The acceleration acquisition unit 24 of the first communication terminal 2 and the acceleration acquisition unit 24 of the second communication terminal 3 each acquire acceleration. Then, the acceleration determination unit 25 of the first communication terminal 2 and the acceleration determination unit 25 of the second communication terminal 3 each determine whether the acceleration value acquired by the acceleration acquisition unit 24 is equal to or greater than a predetermined value.

[0123] For example, the predetermined value may be set so that the acceleration when the first user holds the first communication terminal 2 in his / her hand and shakes it is greater than or equal to the predetermined value, and the acceleration when the first user moves with the first communication terminal 2 in his / her pocket, bag, etc. is less than the predetermined value.

[0124] If the result of the determination is positive, the time setting unit measures the time during which the acceleration value is equal to or greater than a predetermined value, and then the process proceeds to step SP3. If the result of the determination is negative, the process repeats this step.

[0125] (Step SP3) The timing signal generating unit 26 of the first communication terminal 2 and the timing signal generating unit 26 of the second communication terminal 3 each generate a timing signal, and the direct communication unit 22 of the first communication terminal 2 and the direct communication unit 22 of the second communication terminal 3 transmit and receive timing signals to and from each other. Thereafter, the process proceeds to step SP4.

[0126] (Step SP4) The timing determination unit 27 determines whether the difference between the timing at which the direct communication unit 22 transmits the timing signal and the timing at which the direct communication unit 22 receives the timing signal from the second communication terminal 3 is within a predetermined time. If the determination result is a positive determination, the process proceeds to step SP5, and if the determination result is a negative determination, the process proceeds to step SP2.

[0127] (Step SP5) The direct communication unit 22 of the first communication terminal 2 and the direct communication unit (not shown) of the second communication terminal 3 transmit and receive identification information 21A, 21G to and from each other. The terminal storage unit 20 of the first communication terminal 2 stores the identification information of the second communication terminal 3 as identification information 21G, and the terminal storage unit 20 of the second communication terminal 3 stores the identification information 21A of the first communication terminal 2. Thereafter, the process proceeds to step SP6.

[0128] (Step SP6) In the first communication terminal 2, the application signal generation unit 29 generates an application signal, and the terminal network communication unit 23 transmits this to the server device 4. In the second communication terminal 3, the application signal generation unit 29 generates an application signal, and the terminal network communication unit 23 transmits this to the server device 4.

[0129] In addition, the application signal generated by the application signal generation unit 29 of the first communication terminal 2 includes identification information 21G of the second communication terminal 3, and the application signal generated by the application signal generation unit 29 of the second communication terminal 3 includes identification information 21A of the first communication terminal 2. Thereafter, the process proceeds to step SP7.

[0130] (Step SP7) The server network communication unit 41 of the server device 4 receives the application signal. Thereafter, the process proceeds to step SP8.

[0131] (Step SP8) The permission signal generating unit 43 of the server device 4 generates a permission signal, and the server network communication unit 41 of the server device 4 transmits this to the first communication terminal 2 and the second communication terminal 3, respectively. Thereafter, the process proceeds to step SP9.

[0132] (Step SP9) The terminal network communication unit 23 of the first communication terminal 2 and the terminal network communication unit 23 of the second communication terminal 3 each receive a permission signal from the server device 4. This enables the first communication terminal 2 and the second communication terminal 3 to perform network communication. Thereafter, the process proceeds to step SP10.

[0133] (Step SP10) The effector 35 of the first communication terminal 2 selects a screen effect based on the acceleration detected by the acceleration determination unit 25 and the length of time measured by the time measurement unit 28, and the display control unit 32 displays the selected screen effect. The second communication terminal 3 also displays the screen effect in the same manner.

[0134] This means that when a first user of the first communication terminal 2 and a second user of the second communication terminal 3 are facing each other (or standing next to each other) while holding their communication terminals, the screen presentation can be changed by, for example, shaking their hands up and down once, rotating their hands once, or rotating their entire bodies multiple times. Thereafter, the process proceeds to step SP11.

[0135] (Step SP11) The operation receiving unit 30 receives an operation to select at least one piece of image information 21B from the image information 21B stored in the terminal storage unit 20. Thereafter, the process proceeds to step SP12.

[0136] (Step SP12) The terminal network communication unit 23 of the first communication terminal 2 and the terminal network communication unit (not shown) of the second communication terminal 3 transmit and receive image information to and from each other (of course, the timing of this transmission and reception does not need to be synchronized, so transmission can be done freely). Also, audio information may be transmitted and received. Thereafter, the process proceeds to step SP13.

[0137] (Step SP13) The display control unit 32 of the first communication terminal 2 displays the image information 21H received by the terminal network communication unit 23. Furthermore, the display control unit (not shown) of the second communication terminal 3 displays the image information received by the terminal network communication unit (not shown). Furthermore, the audio output unit 34 of the first communication terminal 2 and the audio output unit (not shown) of the second communication terminal 3 may output audio information as sound. The process then ends. The above is a description of an example of the processing of the communication system 1 according to this embodiment.

[0138] <Action and effect> The first communication terminal 2 of this embodiment is equipped with a direct communication unit 22 that transmits and receives mutual identification information 21A, 21G by performing direct wireless communication with another communication terminal (second communication terminal 3), a terminal memory unit 20 that stores multiple pieces of image information 21B, an operation reception unit 30 that receives (by a user) a selection operation of at least one piece of image information 21B from the multiple pieces of image information 21B stored in the terminal memory unit 20, a terminal network communication unit 23 that is capable of performing network communication with the other communication terminal (second communication terminal 3) that transmitted and received the mutual identification information 21A, 21G, and that transmits the image information 21B received by the operation reception unit 30 to the other communication terminal through the network communication and receives image information from the other communication terminal, and a display control unit 32 that displays image information 21H received from the other communication terminal by the terminal network communication unit 23. In this manner, in this embodiment, network communication is performed with another communication terminal (second communication terminal 3) with which identification information has been exchanged by direct wireless communication, so network communication between strangers is prevented, ensuring user safety. Also, since the displayed information is an image rather than text, the information can be easily recognized. Furthermore, the user does not need to perform the operation of inputting text, which simplifies user operation and further improves convenience. Therefore, in this embodiment, it is possible to provide a communication terminal that is safe and convenient for young users when they communicate with each other via telecommunications.

[0139] Furthermore, the display control unit 32 of the first communication terminal 2 according to this embodiment simultaneously displays a plurality of pieces of image information 21H received by the terminal network communication unit 23 from one or a plurality of other communication terminals. In this manner, in this embodiment, by displaying a plurality of pieces of image information 21H (a combination of pieces of image information) received from one other communication terminal (second communication terminal 3), the first user can visually confirm detailed information about the second user. Furthermore, when there are a plurality of other communication terminals performing network communication, by simultaneously displaying (list displaying) the image information 21H received from the plurality of communication terminals, the first user can also visually confirm information about each user. This further improves convenience. Furthermore, by displaying a combination of images such as pictograms, younger users can enjoy communicating with each other.

[0140] In addition, the first communication terminal 2 according to this embodiment further includes an acceleration acquisition unit 24 that acquires acceleration, and an acceleration determination unit 25 that determines whether the acceleration acquired by the acceleration acquisition unit 24 is greater than or equal to a predetermined value, and the direct communication unit 22 transmits identification information to another communication terminal (second communication terminal 3) when the determination result of the acceleration determination unit 25 is a positive determination. In this embodiment, identification information is sent and received when the acceleration is equal to or greater than a predetermined value, so that users who own communication terminals need to move their communication terminals when exchanging (sending and receiving) the identification information of each other's communication terminals, which increases the interest.

[0141] In addition, the first communication terminal 2 according to this embodiment further includes a timing signal generation unit 26 that generates a timing signal when the judgment result of the acceleration judgment unit 25 is a positive judgment, and a timing judgment unit 27 that judges the timing of transmission and reception of the timing signal by the direct communication unit 22, the direct communication unit 22 transmits a timing signal to another communication terminal (the second communication terminal 3) and receives a timing signal transmitted from the other communication terminal (the second communication terminal 3), the timing judgment unit 27 judges whether the difference between the timing at which the direct communication unit 22 transmits the timing signal and the timing at which it receives the timing signal is within a predetermined time, and the direct communication unit 22 transmits identification information 21A to the other terminal (the second communication terminal 3) when both the judgment result of the acceleration judgment unit 25 and the judgment result of the timing judgment unit 27 are positive judgments. In this way, in this embodiment, network communication is enabled when the difference between the timing when the timing signal is sent and the timing when it is received is within a specified time, thereby preventing the user from unintentionally moving the communication terminal and enabling network communication, further improving safety.

[0142] In addition, the first communication terminal 2 according to this embodiment further includes a performance unit 35 that sets a performance based on the acceleration detected in the acceleration determination unit 25 when the terminal network communication unit 23 becomes capable of performing network communication with another communication terminal (second communication terminal 3). In this way, in this embodiment, the presentation changes depending on the acceleration, which increases the interest.

[0143] In addition, the first communication terminal 2 according to this embodiment further includes a time measurement unit 28 that measures the length of time during which the judgment result of the acceleration judgment unit 25 is a positive judgment, and a performance unit 35 that sets a performance based on the length of time when the terminal network communication unit 23 becomes able to perform network communication with another communication terminal (second communication terminal 3). In this way, in this embodiment, the presentation changes depending on the length of time that the acceleration is equal to or greater than a predetermined value, which increases the entertainment value.

[0144] In addition, the first communication terminal 2 according to this embodiment further includes a counting unit 36 ​​that accumulates an accumulated value when direct wireless communication is performed with another communication terminal (second communication terminal 3) in the direct communication unit 22, and the display control unit 32 displays the accumulated value. In this way, in this embodiment, when a user comes within the range of direct wireless communication with a second user of another communication terminal (second communication terminal 3) (for example, when they pass each other), the accumulated value is accumulated and the accumulated value is displayed, thereby increasing interest.

[0145] Moreover, the display control unit 32 of the first communication terminal 2 according to this embodiment displays the schedule of another terminal (second communication terminal 3). In this manner, in this embodiment, the first user of the first communication terminal 2 can know the schedule of the second user of the other communication terminal (second communication terminal 3).

[0146] In addition, the communication system 1 of this embodiment includes a plurality of communication terminals and a server device 4 that performs network communication with each of the communication terminals and allows two of the communication terminals (first communication terminal 2 and second communication terminal 3) that have sent and received identification information to each other to perform network communication, and when the two communication terminals (first communication terminal 2 and second communication terminal 3) are each permitted by the server device 4, they can perform network communication with each other via the terminal network communication unit 23. In this manner, in this embodiment, network communication between communication terminals is possible only if the server device 4 permits it, thereby further improving security.

[0147] Furthermore, the communication system 1 according to this embodiment includes a plurality of communication terminals and a server device 4 having a server network communication unit 41 that performs network communication with each of the communication terminals, and when the judgment result of the timing judgment unit 27 is a positive judgment, the terminal network communication unit 23 transmits an application signal to the server network communication unit 41, and when the server network communication unit 41 receives an application signal from each of two communication terminals (first communication terminal 2 and second communication terminal 3) that have transmitted and received identification information to each other, it transmits an authorization signal to the terminal network communication units of the two communication terminals (first communication terminal 2 and second communication terminal 3), and when the terminal network communication units receive the authorization signal, the two communication terminals (first communication terminal 2 and second communication terminal 3) are able to perform network communication with each other via the terminal network communication units. In this manner, in this embodiment, network communication between communication terminals is possible only if the server device 4 permits it, thereby further improving security.

In this case, the device may include a sorting unit (not shown) that sorts the identification information 21G to one of the friend information based on the acceleration detected by the acceleration determination unit 25, and also sorts the image information 21H and the audio information 21I linked to the identification information 21G to the same friend information.
