However, in order to exchange such information, it is necessary for the other party to support its own information exchange means.

In view of the above, an object of the present invention is to provide an information exchange apparatus capable of smoothly exchanging information with the other party.

To achieve the above object, the present invention provides a human body communication unit that applies information flowing through a human body to the human body and detects information flowing through the human body, an information transfer unit that transmits and receives information through the human body communication unit, and a human body. Provided is an information exchange device having a detection unit that detects the presence of another device that can support the function of a communication unit, and a notification unit that reports a detection result of the detection unit. Such an information exchange device is configured as a mobile phone, for example, and is suitable for exchanging business card information flowing through a human body in a handshake state between mobile phones.

According to the configuration of the present invention, since the reporting unit can understand that the other party's mobile phones are compatible with human body communication regardless of the other party, if you shake hands with the other party in a natural self-introduction Information can be exchanged smoothly. In other words, even if you do not know whether the other party has a mobile phone that supports human body communication, you can first exchange paper business cards and then shake hands to complete natural self-introduction in either case.

According to a specific feature of the present invention, the detection unit includes a wireless communication function unit, and performs detection based on radio waves received by the wireless communication function unit. More specifically, the detection unit performs detection based on the intensity of the radio wave received by the wireless communication function unit. Thereby, when the other party approaches, it can be understood that the other party's mobile phone supports human body communication. According to another more specific feature, the detection unit performs detection based on information conveyed by radio waves received by the wireless communication function unit. As a result, for example, codes indicating compatible models can be exchanged with each other, thereby enabling detection.

According to another specific feature of the present invention, the detection unit performs detection based on information transmitted from the human body communication unit. As described above, for example, when a handshake is performed, it is also possible to detect whether or not the device is a compatible model based on whether or not a code indicating the compatible model is transmitted.

According to another specific feature of the present invention, a control unit is provided that adjusts the interrelationship with other devices detected by the detection unit. More specifically, the information exchange unit can determine the order of information exchange with other devices based on this control unit. Thereby, information exchange is performed smoothly. According to another more specific feature, the reporting unit performs reporting while adjusting the relationship with reporting by other devices based on the control unit. As a result, for example, when making a notification by sound, it is possible to avoid a situation in which the notification cannot be identified due to confusion with the relationship with the notification performed by another reporting unit.

According to another specific feature of the present invention, the control unit includes an operation unit that determines whether communication by the human body communication unit is possible, and the detection unit is configured to be able to detect regardless of whether communication by the human body communication unit is possible. Is done. As a result, it is possible to avoid a situation in which detection cannot be performed depending on the operation state of the information exchange apparatus.

According to another specific feature of the present invention, a reporting unit is provided for reporting the completion of information exchange by the information exchange unit. As a result, it can be confirmed that the information exchange is surely performed by the human body communication. According to another specific feature, a reporting unit is provided that warns that information exchange by the information sending / receiving unit is incomplete. As a result, it can be seen that the information exchange has not been completed due to the short time of shaking hands, etc., and the information can be exchanged by shaking hands again.

According to another aspect of the present invention, a notification sound that constitutes a chord between a notification unit that generates a notification sound related to another device existing in the vicinity and a notification sound by the other device is used as a notification sound by the other device. And a control unit that controls the notification unit so as to be generated in a superimposed manner. This clearly shows that the notification sound is generated from both devices without causing confusion even when the notification sound from other devices is output at the same time. And the distinction from the case where the notification sound is generated only from one side can be made clear.

According to another aspect of the present invention, an information exchange unit that exchanges information via a communication unit, a detection unit that detects that there is another device that can support the function of the communication unit, and a detection result An information exchange comprising a reporting unit for reporting and a control unit for determining a possible pair and a priority order of each pair when there are a plurality of other devices detected. An apparatus is provided. As a result, even when a plurality of pairs are trying to exchange information in parallel, it is possible to make a report without any confusion or interference.

  FIG. 1 is a block diagram showing an example of an information exchange apparatus according to an embodiment of the present invention. In this embodiment, a system including a pair of mobile phones including a first mobile phone 1 and a second mobile phone 101 is configured. The internal structure of the second mobile phone 2 is basically the same as that of the first mobile phone 1, and the corresponding two-digit number is assigned the same number in the corresponding configuration, and the details of the second mobile phone 101 are required unless necessary. Description of is omitted.

The first mobile phone 1 has a first mobile control unit 6 composed of a computer that controls the entire mobile phone, and controls the first telephone function unit 10 and the like according to the operation of the telephone operation unit 8. The first telephone function unit 10 is a part related to a normal telephone function, and includes a voice processing unit, a transmitter, and a receiver. The function of the first portable control unit 6 is executed by software stored in the storage unit 12. The storage unit 12 temporarily stores various data necessary for controlling the entire first mobile phone 1 and also serves as a storage device for information such as address book data to be accumulated and held in the mobile phone. The first portable control unit 6 further controls the display unit 14 to perform GUI display in cooperation with the operation of the telephone operation unit 8 and display the control result. The first portable control unit 6 also controls the sound generation unit 22. This sound generation unit 22 is provided separately from the handset which is a sound output unit, and in conjunction with the display unit 14 generates a notification sound and a warning sound regarding various functions of the first mobile phone, and a speaker in a videophone mode or the like. Also fulfills the role.

The GPS unit 16 obtains information on the latitude, longitude, and altitude, which are absolute position information of the first mobile phone 1, from the satellite or the nearest broadcasting station based on the GPS system and sends the information to the first mobile control unit 6. This absolute position information is displayed on the display unit 14 together with the map under the control of the first portable control unit 6 and provided as navigation information.

The first mobile phone 1 can perform wireless communication via a telephone line including a normal call by the first telephone function unit 10 and the first telephone communication unit 18. The first mobile phone 1 is further provided with a first mobile short-range communication unit 20 using a wireless LAN, Bluetooth (trademark), weak radio waves, etc. Wireless communication is possible. The first portable short-range communication unit 20 is based on a standard that is not problematic in terms of laws and regulations, and has a limited communication area but does not incur charges like a telephone line.

The first portable short-range communication unit 20 transmits the absolute position information acquired by the GPS unit 16 to the GPS unit of the other device in addition to communication such as business card information described later, and the other device transmits the GPS unit. It is possible to receive the absolute position information acquired at As a result, not only the own position but also the positions of other devices can be displayed on the same map on the display unit 14, and the relative relationship between them can be confirmed on the map. Details thereof are described in Japanese Patent Application No. 2007-28393 by the same applicant. The first mobile phone 1 has a camera unit (not shown), can store the captured image in the storage unit 12, and transmits the image to another mobile phone by the first telephone communication unit 18. can do. The first mobile phone 1 is powered by a rechargeable main power supply 24, and the storage unit 12 is further backed up by an auxiliary power supply 26 made of a lithium battery or the like. This prevents volatilization of information stored in the storage unit 12 when the main power supply 24 is discharged or replaced.

The first mobile phone 1 further includes a demodulation / modulation unit 28 and a transmission / reception electrode 30 cooperating therewith. These constitute a human body communication system disclosed in, for example, Japanese Patent Application Laid-Open No. 2006-271798, and the business card information of the owner of the first mobile phone 1 stored in the storage unit 12 is stored in the first mobile control unit. 6 is modulated into a transmission signal by the demodulation / modulation unit 28, and this transmission signal is applied to the human body 34 having the first mobile phone 1 from the transmission / reception electrode 32 via the capacitive coupling 30. In FIG. 1, only the right hand portion in a handshake state is representatively shown as the human body 34. However, since the first mobile phone 1 is held by the left hand of the human body 34 that is not actually illustrated, capacitive coupling is performed. 30 is generated between the transmitting / receiving electrode 32 and a left hand (not shown).

When the transmission signal is applied to the human body 34 as described above, an electrostatic magnetic field or an induction electromagnetic field having a strength corresponding to the transmission signal is induced around the human body 34. Accordingly, when the right hand of the human body 34 is shaken with the right hand of the human body 134 as shown in FIG. 1, an electrostatic magnetic field or an induction electromagnetic field around the human body 34 is transmitted to the human body 134. At this time, if the left hand (not shown) of the human body 134 has the second mobile phone 101, the transmission signal is detected by the capacitive coupling 130 between the left hand and the transmission / reception electrode 132, and this is demodulated by the modulation / demodulation unit 128. Thus, the second portable control unit 106 receives the transmitted business card information and the like and stores it in the storage unit 112. As described above, business card information in the storage unit 12 is transmitted to the storage unit 112 by shaking the human body 34 and the human body 134. Similarly, the business card information of the storage unit 112 is transmitted to the storage unit 112 to the storage unit 12, and electronic business card information exchange by shaking hands is established. In this way, business card information can be exchanged electronically by human body communication. The exchanged business card information can be confirmed at any time by displaying each other on the display unit 14 or the display unit 114, and these can be appropriately processed as electronic data.

The first mobile phone 1 and the second mobile phone 101 in FIG. 1 can communicate with each other between the first telephone communication unit 18 and the second telephone communication unit 118 by infrastructure communication via a communication line base station. On the other hand, the first mobile phone 1 and the second mobile phone 2 can perform direct ad hoc communication by the first mobile short-range communication unit 20 and the second mobile short-range communication unit 120.

FIG. 2 is a basic flowchart of the function of the first portable control unit 6 in the embodiment of FIG. 1, which starts with a power-on operation of the first portable telephone 1. When the flow starts, first, the mobile phone function is initially activated and each function is checked in step S2. In step S4, it is checked whether the display is on. Then, the process proceeds to step 8 where the display is turned on. On the other hand, if the display is not on, the presence / absence of an operation to turn on the display is checked in step S6, and if a display on operation is detected, the process proceeds to step S8. Normally, when the mobile phone is turned on, the display stands up in an on state, so that the process proceeds directly from step S4 to step S8. As will be described later, as long as the mobile phone is on, the check in step S4 is appropriately performed. For example, when the mobile phone is folded and the display is in a standby state in a foldable mobile phone, or the display is not turned off by an auto-off function that detects that there has been no operation for a predetermined time. If it is detected that the mobile phone is opened or some operation is performed to turn on the display, the process proceeds from step S6 to step S8.

In step S8, it is checked whether the business card exchange mode is selected from the operation menu. And if there exists selection, it will enter into the business card exchange mode process of step S10, and if this is complete | finished, it will progress to step S12. Details of the business card exchange mode processing in step S10 will be described later. On the other hand, if the selection of the business card exchange mode is not detected in step S8, the process directly proceeds to step S12. In step S12, it is checked whether the business card display mode is selected from the operation menu. If there is a selection, the business card exchange mode process of step S14 is entered, and when this is completed, the process proceeds to step S16. Details of the business card display mode processing in step S14 will be described later. On the other hand, if the selection of the business card display mode is not detected in step S12, the process directly proceeds to step S16.

In step S16, it is checked whether the skinship mode has been selected from the operation menu. If there is a selection, the process enters the skinship mode process of step S18. The skinship mode process in step S18 is a mode in which e-mail information can be exchanged by human body communication or music reproduction information can be shared in a skinship state in which hands are connected or snuggled with each other. On the other hand, when the selection of the skinship mode is not detected in step S16, the process directly proceeds to step S20. In step S <b> 20, it is checked whether the presence of another mobile phone that supports human body communication can be detected by communication of the first mobile short-range communication unit 20. If there is a detection, the corresponding model detection process of step S22 is entered, and when this is completed, the process proceeds to step S24. Details of the corresponding model detection process in step S22 will be described later. On the other hand, when a mobile phone is not detected in step S20, the process directly proceeds to step S24.

In step S24, it is checked whether or not the function for turning off the display is activated. If this function is not activated, the flow returns to step S4. Thereafter, as long as the display is on, steps S4 to S24 are repeated. On the other hand, when the activation of the function to turn off the display is detected in step S24, the process proceeds to step S26. As described above, for example, when the display is manually turned off by an operation of folding the mobile phone, or when the auto-off function is activated due to no operation for a predetermined time, the display is automatically turned off. Applicable. In step S26, it is checked whether the power-off operation has been performed. If no power-off operation is detected, the flow returns to step S4, and thereafter, steps S4 to S26 are repeated as long as the power is on. On the other hand, when a power-off operation is detected in step S26, the flow is immediately terminated.

If no operation for turning on the display is detected in step S6, the process directly proceeds to step S20. As described above, unless the display is on, the business card exchange mode and the skinship mode cannot be selected, and information is obtained from the first mobile phone by being touched by an unknown person or inadvertently touching an object. Prevents information on the phone from being leaked or skimmed. In addition, the business card exchange mode and skinship mode do not function unless they are intentionally selected. In addition to the above display-on conditions, double security is provided to prevent unexpected information leakage due to human body communication. Measures are taken.

FIG. 3 is a flowchart showing details of the corresponding model detection process in step S22 of FIG. When it is detected in step S20 in FIG. 2 that the mobile phone is nearby, the corresponding model detection process in FIG. 3 starts. For example, when a visitor passes through a reception room, the second mobile phone held by the visitor is detected to be a model compatible with human body communication by communication of the first mobile short-range communication unit 20 held by the customer. Applicable if possible. Note that the flow of FIG. 3 is configured so as to be able to cope with a plurality of visitors. When the flow starts, first, in step S32, information for specifying each of all the cellular phones capable of handling the detected human body communication is received. As the specifying information, for example, a serial number or a telephone number assigned to each mobile phone is used. Note that it is possible to support human body communication by exchanging codes indicating compatible models.

Next, in step S34, it is checked whether or not a plurality of mobile phones that can support human body communication are detected. If a plurality of mobile phones are detected, the process proceeds to step S36, and for example, all possible combinations of each member of the company on the customer side and the company on the reception side are paired. At this time, combinations of members on the same side, for example, members of their own company, are meaningless and are excluded. As a specific example, when company A (members A1, A2) corresponds to company B (members B1, B2, B3), all combinations required in the pairing in step S36 are pair 1 (A1 and B1), Pair 2 (A1 and B2), Pair 3 (A1 and B3), Pair 4 (A2 and B1), Pair 5 (A2 and B2), and Pair 6 (A2 and B3).

Further, in step S38, the priority order of each pair is determined. For example, in the above, the priority order is determined in the order of pair 1, pair 2, pair 3, pair 4, pair 5, and pair 6. Following this, in step S40, the priority order within each pair is determined. For example, in the pair 1, the priority order is the order of A1 and B1. These priorities are automatically determined using, for example, a serial number. That is, the priority order within the pair is the serial number order,
Between pairs, the priority is determined by comparing the younger serial number in each pair with that of the other pair. These priorities are for convenience and are intended to organize the functions of a plurality of mobile phones as will be described later. If only one mobile phone capable of supporting human body communication is detected in step S34, step S36 and step S38 are omitted, and step S40 is directly executed.

When the above pairing and priority order determination are made, the process proceeds to step S42, and it is checked whether any partner of the pair has come within close range of his / her mobile phone. This is the case when you meet someone for a business card exchange and you are alone. Specifically, only the closest person is detected from the difference in distance between the person who can meet for the business card exchange and the other person, and further, it is detected that the person approaches within a predetermined distance. This function is achieved by detecting the strength of radio waves from the other party by the first portable short-range communication unit 20. In this way, step S42 is repeated until a mobile phone approaching within a close range is detected, and detection is awaited. If it is detected in step S42 that the other party in the pair including yourself is approaching within the close range of his / her mobile phone, the process proceeds to step S44. Check if it is sounding. This sound generation means the generation of a sound signal of a predetermined frequency that is generated from both mobile phones when it is confirmed that a pair of mobile phones in close proximity supports human body communication. Will be described later.

In step S44, if the other pair is not sounding, even if the pair of mobile phones makes a sound indicating that it is compatible with human body communication, this may overlap the sound of the other pair and become a disturbing sound. Since there is no worry that the pronunciation of the pair cannot be heard, the process proceeds to step S46. The reason for proceeding to step S46 after checking in step S44 is that there is a possibility that business card exchange will be performed in parallel between a plurality of pairs at the same time. It becomes meaningless to avoid such a situation. In step S46, an entry signal for sound output is preliminarily transmitted from the first portable short-range communication unit 20 to surrounding mobile phones. Next, in step S48, it is checked whether or not an entry signal from another pair has been received within a predetermined adjustment time (for example, 0.1 second). This is to prevent the sound from being generated simultaneously from multiple pairs. When entry signals are transmitted from multiple mobile phones within a predetermined adjustment time, the order of sound generation is adjusted to each other, Make sure that the pair does not overlap at the same time.

When it is detected in step S48 that there is an entry from another pair, the process proceeds to step S50, and it is checked whether or not the order of one's pair has the highest priority among a plurality of entries. If the highest priority is given, the process proceeds to step S52. On the other hand, if no entry from another pair is detected within the adjustment time in step S48, the process immediately proceeds to step S52. In step S52, sound generation or the like is executed, details of which will be described later. In step S44, if there is another pair that is sounding, the sound generation is discontinued for the time being, and the process returns to step S42. Even when the order of the pair is not the highest priority in step S50, the next pronunciation is handed over to another pair, and the process returns to step S42. In this way, the condition that the pair partner is approaching at close range, there is no other pair's pronunciation, and there is no entry of other pair within the adjustment time, or even if their pair has the highest priority Unless all of are satisfied, step S42 to step S50 are repeated.

Next, step S52 will be described in detail. In step S52, first, the approaching pairs are registered with each other so that information can be exchanged by shaking hands. In addition, a chord constituent sound is output from the sound generator 22 based on the priority order within the pair. For example, when a chord composed of “do” and “mi” is pronounced, “do” is pronounced if the priority order of the pair is high. On the other hand, since the other party pronounces “mi” at the same time, the harmony of “do” and “mi” will be heard. As a result, even if both mobile phones of a pair pronounce simultaneously, it can be clearly identified that both are speaking. This is because if only one side is pronounced, only a single sound can be heard. The chord in step S52 is different for each pair. For example, in another pair, the chord is composed of, for example, “Le” and “Fa”. Further, when the pair is sounding by the function of step S44 to step S50, the sound from the other pair is prohibited, so that other sounds are not mixed with the harmony of the pair. In step S52, information indicating that one's own pair is sounding is transmitted to the surrounding mobile phones so that the function of step S44 works on these mobile phones.

When sound generation and information transmission are started in step S52, the flow proceeds to step S54 while continuing to check whether or not a predetermined time (for example, 5 seconds) has elapsed from the start of sound generation. If it has not elapsed, the process returns to step S52 to continue sound generation and information transmission, and if it has been printed, the process proceeds to step S56 to stop outputting chord constituent sounds and to stop transmitting information during sound generation. Next, the process proceeds to step S58, and it is checked whether or not a predetermined time has elapsed since another mobile phone was detected in step S20. If not, the process proceeds to step S60, and it is checked whether or not there is a determined pair that has not yet approached. If there is no inaccessible pair, the flow ends. If it is detected in step S58 that the predetermined time has elapsed, the flow is terminated regardless of whether there is an inaccessible pair. On the other hand, if there is an inaccessible pair in step S60, the process returns to step S42 and waits for the approach.

In the flow of FIG. 3, steps S32 to S40 are executed simultaneously in synchronism with other mobile phones as necessary in all the mobile phones receiving the identifying information. On the other hand, Step S42 to Step S60 are executed simultaneously while paired mobile phones that are approached within a close range, with synchronization as necessary.

FIG. 4 is a flowchart showing details of the business card exchange mode process in step S10 of FIG. When it is detected in step S8 in FIG. 2 that the business card exchange mode has been manually selected, the business card exchange mode process in FIG. 4 is started. Here, the situation in which the selection of the business card exchange mode detected in step S8 in FIG. 2 is performed will be described. The business card is first exchanged with a paper business card. When both of them approach to exchange the business card, a chord is heard by the function of step S52 in FIG. This tells you that both mobile phones are compatible with human body communication and that they are registered with each other for exchanging information, so both take out their mobile phones and manually set them to business card exchange mode, Can be prepared for electronic business card exchange by shaking hands. Alternatively, if a mobile phone equipped with a human body communication function becomes widespread, the business card exchange mode is set before the interview with the other party without waiting for the functions after step S42 in FIG. In any case, if both the setting to the business card exchange mode and the mutual registration are not completed, the business card information is not exchanged even if the hand is shaken, and security is maintained so that the business card information is not inadvertently leaked.

When the process of FIG. 4 starts, first, it is checked in step S72 whether or not a handshake has been performed. If a handshake is detected, the process proceeds to step S74, and it is checked whether or not the handshaked partner is a person registered in step S52 of FIG. And if it is an applicable other party, it will transfer to the business card information exchange process of step S76. Details thereof will be described later. When the business card information exchange process in step S76 is completed, the process proceeds to step S78 to check whether there is business card information currently being displayed. For example, when shaking hands with the second and subsequent opponents, since the business card information acquired by shaking hands with the previous opponent is displayed on the display unit 14, there is business card information being displayed.

If there is business card information being displayed in step S78, the process proceeds to step S80, the display is terminated, and the process proceeds to step S82. On the other hand, if it is not detected in step S78 that there is business card information being displayed, this means that a handshake with the first partner for the user has been performed, and the process directly proceeds to step S82. In step S82, the new business card information received in step S76 is displayed. As a result, when looking at the display part of his / her mobile phone, the title or name of the other party can be confirmed as text information in the same manner as when a business card is received. Next, the display proceeds to step S84 while continuing to display the business card information, and the business card information reception order after the business card exchange mode is selected is stored in the mobile phone. This is for reference when organizing the business card layout described later.

Next, in step S88, it is checked whether or not the received information matches the ID of the existing business card stored in the mobile phone. As this ID, the serial number or telephone number of the mobile phone received in step S32 is used as it is. If it is detected in step S88 that the ID of the received information matches the existing business card ID, the process proceeds to step S90, where the contents of the business card information are compared with the existing information to check whether there is a change in the life information. . This is because there is usually a change in the company, title, etc. when receiving a business card from the same person again.

If there is a change in the business card information in step S90, the process proceeds to step S92, the change information is additionally stored in the ID file of the person, and the process proceeds to step S94. As a result, the history of the person is recorded. On the other hand, if no change in the business card information is detected in step S90, the process directly proceeds to step S94. If no match with the existing business card ID is detected in step S88, the person is the first person to face, and the process proceeds to step S96 to create a new ID file. In step S98, the new business card information is stored in the ID file, and the process proceeds to step S94.

In step S94, the reception date and time of the business card information is stored in the ID file history. Thus, not only when new business card information or existing business card change information is received, but also when there is no change in the business card information, the meeting date and time with the same partner is stored in the ID file history of the person. Thus, information exchange by shaking hands is useful not only for acquiring business card information but also for accumulating visit history with the same partner. Next, in step S100, the presence / absence of a business card exchange mode end operation is checked. If there is no operation, the process proceeds to step S102 to check the presence / absence of a pair that does not exchange business card information. If there is no unexchanged pair, it means that the business card information exchange with all the partners on the spot has been completed, so the flow is automatically terminated. On the other hand, if there is an unexchanged pair, the process returns to step S72, and thereafter, steps S72 to S102 are repeated until there is no unexchanged pair. However, when a manual operation for ending the business card exchange mode is detected in step S100, the flow is immediately terminated regardless of whether there is an unexchanged pair.

FIG. 5 is a flowchart showing details of the business card information exchange process in step S76 of FIG. When the flow starts, it is checked in step S112 whether the order of his / her mobile phone is prioritized in the pair shaking hands. If no priority is given, the process proceeds to step S114 to start transmitting business card information. In this case, on the contrary, the other party has priority and starts receiving business card information. Next, in step S116, it is checked whether the handshake is continued. If it is continued, it is checked in step S118 whether the transmission is completed. If it is not completed, the process returns to step S116, and repeats steps S116 and S118 as long as the handshake continues, and waits for the completion of transmission.

If transmission completion is confirmed in step S118, it will progress to step S120 and it will be checked whether it has received. If the process proceeds from step S118 to step S120, it is not normally received, so the process proceeds to step S122 to start reception. Next, in step S124, it is checked whether the handshake is continued. If it is continued, it is checked in step S126 whether the transmission is completed. If not completed, the process returns to step S124, and as long as the handshake continues, steps S124 and S126 are repeated to wait for reception.

When the completion of reception is confirmed in step S126, the process proceeds to step S128, and the received business card information is temporarily stored. This is because it corresponds to later display and is stored in the storage unit 12 as necessary. This temporary storage is maintained at least until the display in the business card display mode process started immediately after the business card information exchange is unnecessary. When the temporary storage is completed, the process proceeds to step S130, and it is checked whether the transmission has been completed. When the process proceeds from step S128 to step S130, since the normal transmission has been completed, the flow ends.

On the other hand, if the order of the mobile phone is prioritized in the pair shaking hands in step S112, the process proceeds to step S120. Since it has not been received at the stage of shifting from step S112 to step S120, the process proceeds to S122 and reception is started. Next, in step S124, it is checked whether the handshake is continued. If it is continued, it is checked in step S126 whether the transmission is completed. If it is not completed, the process returns to step S124, and as long as the handshake continues, steps S124 and S126 are repeated to wait for reception.

When the completion of reception is confirmed in step S126, the process proceeds to step S128, and the received business card information is temporarily stored. When the temporary storage is completed, the process proceeds to step S130, and it is checked whether or not the transmission has been completed. As a result of the transition from step S112 to step S120, if the process reaches step S130, the transmission has not been normally completed. Therefore, the flow proceeds to step S114 and transmission of business card information is started. Next, in step S116, it is checked whether the handshake is continued. If it is continued, it is checked in step S118 whether the transmission is completed. If it is not completed, the process returns to step S116, and steps S116 and S118 are repeated as long as the handshake continues, and the completion of transmission is awaited.

If transmission completion is confirmed in step S118, it will progress to step S120 and it will be checked whether it has received. In this case, since it has been normally received, the process proceeds to step S130, and it is checked whether transmission has been completed. In this case as well, since the transmission is usually completed, the flow ends. Steps S132 to S138 relate to measures when the handshake is interrupted during transmission or reception of business card information.

First, when it is detected in step S116 that the handshake is no longer continued, the process proceeds to step S132, and a warning display indicating that the business card exchange has not been completed is performed on the display unit 14. At this time, a warning sound output or announcement may also be made from the sound generator 22. Then, the process proceeds to step S134, and it is checked whether or not the handshake is resumed in response to the warning in step S132. Then, unless a handshake is detected, step S132 and step S134 are repeated, and the resumption of the handshake is awaited. If a handshake is detected in step S134, the process returns to step S114, and retransmission is started.

On the other hand, when it is detected in step S124 that the handshake is no longer continued, the process proceeds to step S136, and a warning display indicating that the business card exchange has not been completed is performed on the display unit 14 (and the sound generation unit 22 if necessary). . Then, the process proceeds to step S138, and it is checked whether or not the handshake is resumed in response to the warning in step S136. Unless a handshake is detected, step S136 and step S138 are repeated, and the resumption of the handshake is awaited. If a handshake is detected in step S138, the process returns to step S122 and re-reception is started.

FIG. 6 is a flowchart showing details of the business card display mode process in step S14 of FIG. When it is detected in step S12 in FIG. 2 that the business card display mode is manually selected, the business card display mode process in FIG. 6 is started. First, in step S142, it is checked whether the conference display mode is set by selecting a menu. The meeting display mode is a mode in which the exchanged paper business cards are arranged on the desk corresponding to the sitting position of the opponent, and the received title and name are laid out on the display unit 14 corresponding to the sitting position of the opponent. is there.

When the setting of the conference display mode is detected in step S142, the process proceeds to step S144, and the business card information exchanged in the latest business card exchange mode period is read from the storage unit 12. Specifically, the latest operation times of the business card exchange mode selection operation in step S8 of FIG. 2 and the business card exchange mode end operation of FIG. 4 are detected, and all business card information received during that time is read. This corresponds to the business card information of all the other members who are seated after exchanging business cards at the beginning of one meeting. In the case of paper business cards, business cards are often not exchanged between known people, so it is not possible to arrange the business cards of the people on the desk. Even if it exists, the business card information is automatically exchanged again, and this is temporarily stored in the mobile phone. Therefore, the business card information of all the other parties can be displayed on the display unit 14 at each meeting, which assists human memory.

In step S146, the display auto-off function is prohibited. In the conference display mode, it is expected to display the partner's business card information list on the display unit 14 without operating the mobile phone for a long time. This is to prevent the business card information list display from being automatically turned off during the meeting.

Next, in step S148, it is checked whether the arrangement in which the other party is seated is automatically detected based on the information of the first portable short-range communication unit 20. This is based on triangular distance measurement by exchanging radio wave intensity information among a plurality of mobile phones. If the position of the seat can be automatically detected in step S148, the process proceeds to step S150 to automatically lay out the seat according to the title and name of the other attendee from the received business card information, and display the list on the display unit 14. Then, the process proceeds to step S152.

On the other hand, when it is determined in step S148 that the position of the seat cannot be automatically detected, the process proceeds to step S154 to display the title and name of the other party attendee from the received business card information with reception order information. To list. This reception order information is stored through step S84 in FIG. Then, the process proceeds to step S156, and it is checked whether or not there has been a manual layout change operation based on reception order information and facial features based on memory. This corresponds to arranging paper business cards on a desk when they are received. When a manual layout change operation is detected in step S156, the process proceeds to step S158, where the title and name of the other party attendee are displayed in a list on the display unit 14 according to the changed layout, and the process proceeds to step S152. On the other hand, if no manual operation is detected in step S156, the process directly proceeds to step S152.

In step S152, it is checked whether or not there has been an operation for selecting a specific individual from the list display of the display unit. If there is this operation, the process proceeds to step S160, and all business card history information related to the selected person is enlarged and displayed on the display unit 14 for a predetermined time. When the predetermined time has elapsed, the enlarged display is automatically terminated and the list display is resumed, and the process proceeds to step S162. It should be noted that the transition from step S160 to step S162 may be a transition by manual operation in addition to such an automatic transition when a predetermined time elapses. On the other hand, if no personal selection operation is detected in step S152, the process directly proceeds to step S162.

In step S162, it is detected whether or not there has been an operation for ending the conference display mode. If there is no detection, the process returns to step S152. Hereinafter, unless a conference display mode end operation is detected, step S152, step S160, and step S162 are repeated, and the list display of business card information is continued, and the detailed history of a specific individual can be confirmed as needed. On the other hand, when the conference display mode end operation is detected in step S162, the process proceeds to step S164, and the temporary storage of the received business card information performed in step S128 of FIG. 5 is deleted, and the process proceeds to step S166. If the conference display mode setting is not detected in step S142, the process directly proceeds to step S166.

In step S166, it is checked whether or not the normal display mode is set. If the setting is detected, the process proceeds to step S168 to enter the business card information search and display process. In step S168, based on the business card information database stored in the storage unit 12, depending on the GUI of the telephone operation unit 8 and the display unit 14 under the control of the first portable control unit 6, the search condition is set and searched. Can be executed. The search result is displayed on the display unit 14. When the business card information search / display processing is completed according to the termination procedure in step S168, the flow of the business card display mode is terminated. If the normal display mode setting is not detected in step S166, the flow ends immediately.

Although the above embodiment is a mobile phone, the present invention is not limited to this. For example, the functions relating to the business card information exchange described above may be incorporated in another portable device such as a personal digital assistant (PDA) or a portable music player in place of the cellular phone. It is also possible to incorporate various functions related to the business card information exchange in the wristwatch. Furthermore, it is also possible to incorporate various functions relating to the business card information exchange into a business card holder for inserting a paper business card. The functions related to the business card information exchange can be incorporated not only in one device but also in a plurality of devices. For example, the modulation / demodulation unit 28 and the transmission / reception electrode 32 in FIG. 1 are incorporated into a wrist watch together with the minimum configuration and the weak radio wave communication function necessary for controlling them, and other functions are incorporated into the wrist watch and the weak radio wave communication function. A communicable personal computer, a bag, or the like, which is not necessarily close to the human body, may be configured so as to be divided into devices and tools. Further, the function capable of communicating with the wristwatch by the weak radio wave communication as described above is not necessarily limited to the case where the portable device is divided and may be provided as a facility of the conference room.

In the above embodiment, the function using the first portable short-range communication unit 20 is shown in FIG. 3 as the details of the corresponding model detection process in step S22 of FIG. 2, but the implementation of the present invention is limited to this. It is not a thing. For example, it is possible to configure such that communication is attempted by human body communication when a handshake is performed, and if there is a response such as a code indicating that it is a compatible model, the partner model is compatible. In this case, it is possible to detect at once whether or not the other party can respond with a single handshake and then exchange business card information at once. In addition, instead of the above, it is possible to configure so that only the confirmation of whether or not the other party can handle is performed by human body communication at the first handshake. In this case, after confirming that the other party can handle the first handshake, the business card exchange mode shown in FIG. 2 is selected, and then the second handshake is performed to exchange the business card information similar to FIG. I do.
