FIG. 1 is a block diagram of Example 1 of the information input / output device according to the embodiment of the present invention. The first embodiment includes a music data output device 12 including a mobile phone 4 held by the user 2, a user-owned headphone 6 worn on the head of the user 2, and a touch panel 10 touched by the finger 8 of the user 2. The system is configured. In the first embodiment, with the system configuration as described above, the audio signal of the music specified by touching the finger 8 of the user 2 is guided to the headphones 6 by human body communication using the body of the user 2, and the finger 8 of the user 2 is also used. The music data designated by touching can be downloaded to the mobile phone 4 by human body communication using the body of the user 2.

The cellular phone 4 has a cellular phone control unit 14 formed of a computer that controls the entire cellular phone, and controls the telephone function unit 16 and the like according to the operation of the cellular phone 4. The telephone function unit 16 is a part related to a normal telephone function, and includes a communication function unit, a voice processing unit, a transmitter, and a receiver. The function of the mobile phone control unit 14 is executed by software stored in the storage unit 18. The storage unit 18 temporarily stores various data necessary for the control of the entire mobile phone 4 and also serves as a storage device for information to be accumulated and held in the mobile phone such as address book data. The storage unit 18 is also a storage device for music data downloaded from the music data sales device 12. The storage unit 18 has a non-volatile memory unit composed of a hard disk and a volatile memory unit composed of a semiconductor memory or the like in order to realize the above functions.

The mobile phone control unit 14 further controls the display unit 15 of the mobile phone 4 to perform GUI display in cooperation with the operation of the mobile phone and display the control result. The display unit 15 may be configured as a touch panel and may also serve as a GUI operation unit. The mobile phone control unit 14 controls a sounding unit (not shown) provided separately from the handset of the telephone function unit 16 and generates notification sounds and warning sounds related to various functions of the mobile phone in conjunction with the display unit. At the same time, it also serves as a speaker in the video phone mode of the mobile phone 4. The mobile phone 4 also has a GPS unit (not shown), and obtains the latitude, longitude, and altitude information, which is the absolute position information of the mobile phone 4, from a satellite or the nearest broadcasting station based on the GPS system. This is sent to the telephone control unit 14. This absolute position information is displayed on the display unit together with the map under the control of the mobile phone control unit 14, and is provided as navigation information.

The cellular phone 4 can perform wireless communication via a telephone line including a normal call by the telephone function unit 16. In addition to this, the mobile phone 4 is provided with a short-range communication unit 20 using a wireless LAN, Bluetooth (trademark), weak radio waves, etc., and wirelessly connected to other mobile phones or station ticket gates or the like existing in the short-range communication range Communication is possible. The 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. As described above, the mobile phone 4 can communicate with other mobile phones by infrastructure communication via the base station of the communication line, and directly communicate with other mobile phones or station ticket gates by the short-range communication unit 20. Ad hoc communication is possible.

In addition, the mobile phone 4 has a camera unit 22, can store the captured image in the storage unit 18, and can transmit the image to another mobile phone by the telephone function unit 16. The mobile phone 4 is powered by a rechargeable main power source (not shown), and the storage unit 18 is further backed up by an auxiliary power source (not shown) made of a lithium battery or the like. This prevents the information stored in the volatile memory unit of the storage unit 18 from volatilizing when the main power supply is discharged or replaced.

The cellular phone 4 further includes a modulation / demodulation unit 24 and a transmission / reception electrode 26 cooperating therewith. The transmitting / receiving electrode 26 is provided at a position close to the human body surface, such as the outer wall of the mobile phone 4. The modulation / demodulation unit 24 and the transmission / reception electrode 26 constitute a human body communication system disclosed in, for example, Japanese Patent Application Laid-Open Nos. 2004-282733 and 2006-271798, and perform communication using the human body as a medium. For example, when music data or the like stored in the storage unit 18 is converted into an audio signal by the audio signal output unit 28 under the control of the mobile phone control unit 14 and output to an audio signal, the modulation / demodulation unit 24 generates a user-specific frequency. The transmission signal is applied to the human body of the user 2 holding the mobile phone 4 from the transmission / reception electrode 26 as indicated by an arrow 30. In addition to the case where the mobile phone 4 is held in the hand of the user 2, the mobile phone 4 may be stored in a place close to the human body surface of the user 2, such as a pocket of clothes.

When a transmission signal is applied to the human body of the user 2 as described above, an electrostatic magnetic field, an induction electromagnetic field, or a quasi-electrostatic field (hereinafter collectively referred to as “human body surface field”) having a strength corresponding to the transmission signal is generated. It is induced around the human body of the user 2. The transmission signal propagated by the human body surface world is received by the receiving electrode 32 of the headphone 6, and is demodulated into an audio signal by the demodulating unit 34, so that it is delivered from the sound generating unit 36 to the user 2 as music. With such human body communication, the headphones 6 can be sounded cordlessly by the audio signal from the mobile phone 4. In this case, since the frequency of the transmission signal is unique to the user, no information is leaked even if there is contact with the human body of the user 2 from the outside which is not set to this frequency.

Next, details of the music data selling apparatus 12 that provides data to be downloaded to the mobile phone 4 and an audio signal for sounding the headphones 6 will be described. When participating in this system, the frequency of the transmission signal for human body communication in the headphones of the user 2 needs to be set to the published frequency for listening to the music data selling apparatus. The music data sales apparatus 12 is installed in an audio shop or the like, and is provided with a touch panel 40 having a display surface 38 for displaying a list or list of a large number of music for selection by the user 2. Data for display is stored in the display data storage unit 42, and the display driver 44 performs the above display under the control of the sales device control unit 46 based on this data. The user 2 touches the desired music title or jacket image displayed on the display surface 38 with the finger 8. Thus, in the case of trial listening, the audio signal from the music data selling device 12 is transmitted to the receiving electrode 32 as shown by the arrow 48 by the human body communication through the touched finger 8, and the headphones 6 are sounded. In the case of music purchase, music data from the music data sales device 12 is transmitted to the transmission / reception electrode 26 as shown by an arrow 50 by human body communication through the touched finger 8 and is transmitted to the storage unit 18 of the mobile phone 4. Downloaded.

First, in the case of trial listening, when the finger 8 of the user 2 touches one of the desired music title or jacket image display displayed on the display surface 38, the signal is detected by the touch position detection unit 48. Then, based on the processing of the result, the sales device control unit 46 recognizes the music touched by the finger 8. The recognized music is stored in the storage unit 55. In response to the recognition of the music, the display driver 44 controls the display on the display surface 38, displays a selection cursor around the touched music name or jacket image display, displays that the music has been recognized, and notifies the user 2 of it. . Note that the user may be recognized by blinking the jacket image or changing its color instead of the selection cursor.

Simultaneously with the display of the selection, the sales apparatus control unit 46 calls the recognized music from the music data storage unit 56, converts it into an audio signal at the audio signal output unit 58, and outputs it. When the audio signal is output, the modulation / demodulation unit 60 modulates the audio signal into a transmission signal having a public listening frequency, and applies it to the surface of the display surface 38 from the transmission / reception electrode 62. The applied transmission signal is transmitted to the reception electrode 32 of the headphone 6 by human body communication indicated by an arrow 48 through the finger of the user 2 touching the display surface 38. Since this is demodulated by the demodulator 34 and produced by the sound generator, the user 2 can listen to the music selected by the finger 8 on the touch panel 40. In order to continue the audition, it is necessary to keep the finger 8 in contact with the display surface 38 of the touch panel 40. When the finger 8 is released, the touch position detection unit 54 detects this, and the sales device control unit 46 cancels the audition and stops the audio signal output from the audio signal output unit 58. Although the audio signal output is stopped, the selection result of the music is stored in the storage unit 55. Therefore, even if the finger 8 is released, the selection display continues unless the selection is canceled.

On the other hand, in the case of music purchase, the frequency of the transmission signal for human body communication of the mobile phone 4 needs to be set to a purchase-dedicated frequency published by the music data sales apparatus. This frequency is different from the above listening frequency. Under such conditions, when the finger 8 of the user 2 touches the button for instructing the purchase of the selected music displayed on the display surface 38, the signal is detected by the touch position detection unit 48, and the sales device The control unit 46 calls the music data of the music confirmed to be purchased from the music data storage unit 56. The called music data is modulated by the modulation / demodulation unit 60 into a transmission signal having a frequency dedicated to data purchase, and applied to the surface of the display surface 38 from the transmission / reception electrode 62. The applied transmission signal is transmitted to the transmission / reception electrode 26 of the mobile phone 4 by human body communication indicated by the arrow 50 through the finger of the user 2 touching the display surface 38. This is demodulated by the demodulator 24 and stored in the storage unit 18. Along with this, purchase settlement processing is performed through the same human body communication path. When all are completed, a message to that effect is displayed, and it is sufficient to confirm this and release the finger 8. Since the music data is compressed data, the time for touching the finger 8 is much shorter than that for trial listening. In addition, since the frequency of the transmission signal for data communication is different from the frequency for trial listening, the data communication signal is heard from the headphones 6 and does not feel uncomfortable.

The music data sales apparatus 12 further includes a trial listening and music sales means for users who do not have human body communication means. Specifically, the audio signal output unit 58 outputs an audio signal to the connection unit 64, and a user who does not have human body communication means can audition by connecting a normal wired headphone to the connection unit 64. . At this time, the operation of the touch panel 40 is the same as in the case of human body communication. In addition, when purchasing music, the music data selling device 12 can also output music data from the short-range communication unit 66. The music data output from the short-range communication unit 66 communicates with the short-range communication unit 20 of the mobile phone 4 so that the music data can be transferred and purchased. In the case of purchase, the operation of the touch panel 40 and the like are basically the same as in the case of human body communication, but an operation for starting short-range communication is necessary.

FIG. 2 is a display screen diagram illustrating the display on the display surface 38 of the touch panel of the music data sales apparatus 12 according to the first embodiment. The description will be made with reference to the numbers in FIG. FIG. 2A is a screen for trial listening, where music jacket images 102 and 104 and the like are displayed together with a song name and a comment 106 such as a performer. The user 2 can select a music piece by touching one of the jacket images with the finger 8. FIG. 2A shows a state in which the finger 8 of the user 2 is touching the jacket image 104, which is detected by the function of the touch position detection unit 54 of the touch panel 38 and the selection cursor 108 is around the jacket image 104. And the user 2 is notified that the selection of the music is recognized by the touch panel 40.

On the other hand, the headphone icon 110 is displayed when the headphone 6 is in a human body communication state through the finger 8 of the user 2 and there is a response from the headphones according to the human body communication protocol. As a result, the user can know that human body communication is possible. When the headphone icon 110 is displayed, the audio signal of the music for trial listening corresponding to the selected jacket display 104 is sent to the headphone 6 by human body communication, so that the user 2 listens to this through the headphone 6. Can do.

Note that once the music selection is recognized by the music data sales device 12, as long as the finger 8 is continuously touching the display surface 38, the audition of the same music is continued even if the finger 8 is displaced from the jacket image 104. The On the other hand, when the user 2 releases the finger 8 from the display surface 38, the touch panel 40 detects this and stops listening to the music. At the same time, the display of the headphone icon 110 disappears. Incidentally, when the finger 8 is separated from the display surface 38, the human body communication path itself is cut off. On the other hand, even if the finger 8 moves away from the display surface 38, the selection of the music corresponding to the jacket display 104 is stored and held in the storage unit 55 of the music data sales apparatus 12, and the display of the music selection cursor 108 is also continued. . In this state, when the finger 2 of the user 2 touches the purchase button 112, the selected music is purchased, and the purchase screen shown in FIG. 2B is displayed. On the other hand, when the finger 8 of the user 2 touches the end button 114, the storage of the storage unit 55 storing the selected music is cleared and the display of the music selection cursor 108 is also turned off.

In FIG. 2B, the jacket image 104 corresponding to the selected music piece is enlarged and a detailed comment 116 such as lyrics and a player profile is displayed. In this state, the frequency of the transmission signal for human body communication is set to a purchase-only frequency. When the authentication / download / settlement button 122 is touched on the screen of FIG. 2B, a human body communication path is formed between the music data sales apparatus 12 and the mobile phone 4 through the finger 8, and the mobile phone 4 is connected according to the human body communication protocol. When there is a response, the mobile phone icon 118 and the human body communication icon 120 are displayed. At the same time, the touch position detection unit 54 detects a touch on the authentication / download / settlement button 122, and the music data is transmitted from the music data selling device 12 to the mobile phone 4 including authentication of the mobile phone 4. A series of processing up to electronic settlement processing related to fee payment between the sales apparatus 12 and the mobile phone 4 is performed.

Even in the state of FIG. 2B, if the end button 114 is touched without touching the authentication / download / settlement button 122, the process is canceled without entering the music purchase. Further, as already described, the music data selling device 12 can perform music sales transactions with the mobile phone 4 by the short-range communication unit 66 as well. When there is a response from the mobile phone 4, only the mobile phone icon 118 is displayed and the human body communication icon 120 is turned off. The music listening and purchasing functions as described above will be further described in detail with reference to the following flowchart.

FIG. 3 is a flowchart showing the function of the sales apparatus control unit 46 in the first embodiment of FIG. The flow starts when power is supplied to the music data sales apparatus 12. When the flow starts, display of a preview screen is instructed in step S2. As a result, the display as shown in FIG. At this stage, the selection cursor 108 and the headphone icon 110 in FIG. 2A are not yet displayed. Next, in step S4, whether or not the touch panel 40 is touched is checked. If no touch is detected, steps S2 and S4 are repeated to wait for the touch.

When a touch is detected in step S4, the process proceeds to step S6, and a human body communication frequency for trial listening is automatically set. This human body communication frequency for listening is always automatically set on the headphone 6 side. Next, a touch position detection process is performed in step S8, and when the touch position is specified, the process proceeds to step S10 to check whether or not the selected portion of the sample music is touched. Specifically, this corresponds to detection of the finger 8 touching any one of the jacket images 102 and 104 of the music in FIG. When it is detected in step S10 that the sample music touch is detected, the process proceeds to step S12 to enter a sample music process for the selected music, and when the sample process is completed, the process proceeds to step S14. Details of the trial listening process in step S12 will be described later. As will be described later, when it is detected in step S10 that a sample music touch is detected, a selection cursor 108 as shown in FIG. 2A is displayed around the jacket image 104 of the touched music through the sample processing 12. In addition, the music selection result is stored in the storage unit 55. On the other hand, when it is desired to detect the sample music touch in step S10, the process directly proceeds to step S14.

In step S14, it is checked whether or not the purchase button 112 has been touched. If a purchase button touch is detected, the process proceeds to step S16 to check whether or not the music selection memory is stored in the storage unit 55. If there is a memory, the process proceeds to step S18 to instruct the display of the purchase screen. As a result, a purchase screen as shown in FIG. 2B is displayed. At this stage, the mobile phone icon 118 and the human body communication icon 120 in FIG. 2B are not displayed yet.

Further, in step S20, the purchase human body communication frequency is automatically set. This human body communication frequency for trial listening is automatically set on the mobile phone 4 side as long as the human body communication mode is activated on the mobile phone 4. Next, the purchase process of step S22 is started. When the purchase process is completed, the process proceeds to step S24. Details of the trial listening process in step S22 will be described later. Note that if it is desired to detect the purchase button touch in step S14, the process directly proceeds to step S24.

On the other hand, when the music selection memory is not detected in step S16, the process proceeds to step S23, the guidance display for prompting the music selection operation is instructed, and the process returns to step S2. This guidance display disappears automatically at a predetermined time. That is, when the purchase button 112 is touched without touching any of the music jacket displays in FIG. 2A, the purchase screen of FIG. 2B is not displayed, and the audition screen of FIG. Maintained.

In step S24, it is checked whether or not the end button 114 has been touched. If the end button touch is detected, the process proceeds to step S26, the music selection storage in the storage unit 55 is cleared, and the process returns to step S2. In step S2, the preview screen display is instructed, so if the purchase screen of FIG. 2B is displayed, the screen returns to the preview screen of FIG. That is, the end button 114 in the preview screen display state as shown in FIG. 2A functions as a music selection cancel button, and the end button 114 in the purchase screen display state as shown in FIG. Functions as a return button to the preview screen.

On the other hand, when the end button touch is not detected in step S24, the process proceeds to step S28, and it is checked whether or not a predetermined time has elapsed since the touch on the panel was detected in step S4. The process proceeds to step S28 when the finger 8 touches a position outside the predetermined position on the display surface 38 of the touch panel 40. In such a case, the touch panel 40 does not react, but the transmission signal of human body communication is applied to the entire display surface 38 from the transmission / reception electrode 62, so that the human body communication itself is no matter where the finger 8 touches the display surface 38. It is in a possible state.

If the elapse of the predetermined time is not detected in step S28, the process returns to step S24, and steps S24 and S28 are repeated. If an end button touch is detected during this time, the process proceeds to step S26 as described above. On the other hand, when the predetermined time has passed without detecting the end button touch, the process proceeds to step S30 to check whether the power supply is cut off. If the power supply continues, the process returns to step S2. As long as the power supply is continued in this way, Step S2 to Step S30 are repeated to deal with various situations.

In addition, when returning to step S2 by touching the end button as described above, the music selection storage in the storage unit 55 is cleared, but when returning to step S2 after a predetermined time has elapsed, the music selection state is maintained. Accordingly, when the screen automatically returns to the trial listening screen of FIG. 2A without touching the end button 114, the purchase screen of FIG. 2B can be re-transferred by touching the side purchase button 112. On the other hand, when it is detected in step S30 that the power supply is cut off, the flow ends. Note that, for a predetermined end process after the power supply is turned on, the music data sales apparatus 12 is provided with a capacitor for storing electric power that guarantees at least the operation for a predetermined time in step S28.

FIG. 4 is a flowchart showing details of the trial listening process in step S12 of FIG. When the flow starts, first, in step S32, the music corresponding to the detected touch position is recognized, and the selection cursor 108 around the jacket display 104 of the recognized music is displayed. Next, in step S34, it is checked whether or not the memory of the already selected music is held in the storage unit 55. If there is a memory, the process proceeds to step S36 and is erased, and the process proceeds to step S38. On the other hand, if the selected music storage is not detected in step S34, the process proceeds directly to step S38.

In step S38, the music newly recognized by the current touch is stored in the storage unit 55, and the data of the newly recognized music is called in step S40. In step S42, an instruction to convert the called data into an audio signal is issued. In step S44, it is checked whether or not there is a response from the headphones 6 based on the human body communication protocol. If there is a response, this is displayed in step S46. Thereby, the headphone icon 110 in FIG. 2A is displayed.

When human body communication is established between the music data sales apparatus 12 and the headphones 6 in this way, an instruction to modulate an audio signal into a transmission signal for human body communication is issued in step S48, and the modulated audio signal is transmitted. Is applied to the transmitting / receiving electrode 62 in accordance with the instruction in step S50. Through the above, in step S52, it is checked whether or not the selected sample music is over and the output of the audio signal is complete. If not finished, it is checked in step S54 whether the touch on the touch panel is continued. As a result, when the touch continuation is detected, the process returns to step S52, and steps S52 and S54 are repeated unless the audio signal is finished or the finger 8 leaves the display surface 38.

If the touch continuation is not detected in step S54, the process proceeds to step S56 to check whether the end button 114 is touched. If the end button 114 is not touched, the process proceeds to step S58, and it is checked whether or not the headphones have been auditioned by human body communication. If it is a human body communication trial listening, the process proceeds to step S60, instructing the end of the trial listening of the selected music piece and instructing the display to that effect, and the flow is finished. This display is performed, for example, by blinking the display of the purchase button 112 in FIG. 2A to suggest the next operation. In this way, in the case of music preview by human body communication, even if the audio signal is not terminated in the middle of the music, this is detected in step S54 by speaking the finger 8, and the music preview is terminated in step S60.

On the other hand, if it is not detected in step S58 that the audition is based on human body communication, it means that the audition is performed by connecting headphones to the connection unit 64 in a wired manner, so that the finger 6 has left the touch panel. Returning to step S52, as long as the audio signal continues, the trial listening to the music selected by the touch is continued. Regardless of whether or not the communication is a human body, when the end of the audio signal is detected in step S52, or when the touch of the end button 114 is detected in step S56, the process immediately proceeds to step S50.

When there is no human body communication response from the headphones 6 in step S44, the process proceeds to step S62, and the headphone icon 110 is not displayed. In step S64, an audio output to the connection unit 64 is instructed, and the process proceeds to step S52. This is to cope with trial listening performed by connecting headphones to the connection unit 64 by wire. In this case, as described above, if the music is recognized by the touch of the finger 8, whether the audio signal is finished or the end button is touched without continuing the touch of the finger 8 thereafter. Unless you do, you can continue listening to your preferred headphones.

FIG. 5 is a flowchart showing details of the purchase process in step S22 of FIG. When the flow starts, it is first checked in step S70 whether or not an authentication operation has been performed within a predetermined time after the purchase screen shown in FIG. 2B is displayed. If no operation within a predetermined time is detected, the flow is immediately terminated, and the process proceeds to step S24 in FIG. As described above, if the authentication / download / settlement button 122 is not touched for a predetermined time after the purchase screen in FIG. 2B is displayed, the selection memory is maintained or cleared, Return to the audition screen of 2 (A). Needless to say, the selection memory is maintained when it is detected in step S28 that a predetermined time has elapsed, and the selection memory is cleared when the end button touch is detected in step S24. Is the case.

On the other hand, if an authentication operation is detected within a predetermined time in step S70, the process proceeds to step S72. The detection of the authentication operation is detection of a touch on the authentication / download / settlement button 122 as mentioned above. In step S72, it is checked whether there is a response based on the human body communication protocol from the mobile phone 4 through the touched finger 8. In step S72, the purchase human body communication frequency has already been set in step S20 of FIG. 3, and the music data sales apparatus 12 is in a state in which human body communication with the mobile phone 4 is possible. When a response from the mobile phone 4 is detected in step S72 and the human body communication between the music data selling device 12 and the mobile phone 4 is established, the process proceeds to step S74 to display a human body communication response. In step S76, the mobile phone response display is displayed. I do. Each of these corresponds to displaying the human body communication icon 120 and the mobile phone icon 118 in FIG.

Next, in step S78, authentication processing is performed as to whether or not a transaction by human body communication is allowed. This corresponds to the ID and password authentication work determined in advance by a contract between a company that manages the music data selling device 12 and the user 2 who owns the mobile phone 4. This authentication method can be other methods, such as biometric authentication in the embodiments described later. When the human body communication authentication process in step S78 is completed, the process proceeds to step S80 to check whether the authentication is OK. If it is OK, an instruction to call the purchase data of the music selected in step S82 and to modulate it to a transmission signal for human body communication is issued, and the transmission signal of the modulated music data is in accordance with the instruction of step S84. Applied to the transmission / reception electrode 62. Thereby, the music data is transmitted to the mobile phone through the finger 8. However, the music data at this stage is in a temporary transmission state and cannot be reproduced unless an enabling signal described later is received.

In step S86, it is checked whether or not the finger 80 touches the touch panel. As a result, when the continuation of touch is detected, the process proceeds to step S88 to check whether or not the temporary transmission of the music data is completed. If temporary transmission has not been completed, the process returns to step S86. Thereafter, unless temporary transmission is completed or the finger 8 leaves the display surface 38, steps S86 and S88 are repeated to continue temporary transmission of music data. When the completion of provisional transmission is detected in step S88, the human body communication settlement process in step S90 is entered. This is a process of executing electronic settlement between a bank account of a company that manages the music data selling apparatus 12 decided in advance and a bank account of the user 2 who owns the mobile phone 4 by a predetermined procedure.

When the human body communication settlement process in step S90 is completed, it is checked in step S92 whether the settlement is OK. If the account does not exist or the deposit amount is insufficient, the check in step S92 is not OK. When the settlement OK is confirmed in step S92, the process proceeds to step S94, and an activation signal for validating and reproducing the temporary data is transmitted. Through the above, in step S98, reconfirmation of whether or not all the processes are OK is performed. If OK, the flow ends. On the other hand, if all the processes are not confirmed in step S98, the process proceeds to step S86, and the process from step S86 to step S98 can be performed again. This is a response to any unexpected communication trouble. This redo can be performed any number of times as long as the loop from step S86 to step S98 is not exited.

On the other hand, when the touch continuation cannot be detected in step S86, the process proceeds to step S100. This means that the human body communication path via the finger 8 has been cut off, and in step S100, the human body communication icon 120 in FIG. Then, while maintaining this warning, in order to give a time delay for performing re-authentication in the next step S102, the flow progresses for a predetermined period of time. This re-authentication is an operation in which the finger 8 is again touched to the authentication / download / settlement button 122. When this waiting time has elapsed, it is checked in step S104 whether or not the NG detection in step S98 has reached the third time, and if applicable, the flow is immediately terminated. On the other hand, if it is not detected in step S104 that NG has reached the third time, the process returns to step S70, and the flow of FIG. 5 can be restarted from the beginning. The reason for returning to step S70 is to immediately end the flow when the finger is not retouched regardless of the standby in step S102. On the other hand, if the finger 8 is touched again to the authentication / download / settlement button 122 when returning to step S70, the process proceeds to step S72, so that the flow of FIG. 5 can be repeated from the establishment of human body communication.

On the other hand, when the human body communication response from the mobile phone 4 is not detected in step S72, the process proceeds to step S106, and between the short-range communication unit 66 of the music data selling apparatus 12 and the short-range communication unit 20 of the mobile phone 4. It is checked whether there is a response from the mobile phone 4 based on the short-range communication protocol. If there is no response, the music data cannot be purchased through communication, and the flow is immediately terminated. On the other hand, if a near field communication response from the mobile phone 4 is detected in step S106, the process proceeds to step S108, and a mobile phone response display is performed. This corresponds to displaying only the mobile phone icon 118 in FIG. Then, the flow shifts to the near field communication process of step S110, executes the authentication / download / settlement process for music data purchase by a predetermined near field communication procedure, and ends the flow.

In the first embodiment as described above, the headphone 6 is configured as a personal possession of the user 2, but may be configured as a dedicated listening headphone provided in an audio shop where the music data selling device 12 is installed. In this case, since the transmission signal for the human body communication for the trial listening can be set only for the audio shop, it is not necessary to disclose it to the outside, and it is not wiretapped by means other than the headphones provided in the audio shop.

In addition, as a personal listening device of the user 2, a handset included in the telephone function unit 16 of the mobile phone 4 itself can be used instead of the headphones 6. In this case, the frequency of the transmission signal for the human body communication of the mobile phone 4 needs to be set to the frequency for trial listening. As a result, when the audio signal of the music designated by the user 2 is modulated into a transmission signal of the trial listening frequency and output from the music data selling device 12, it passes through the finger 8 of the user 2 touching for music designation. This is transmitted to the transmitting / receiving electrode 26 of the mobile phone 4 by human body communication indicated by the arrow 50. The received transmission signal is demodulated by the modulation / demodulation unit 24 and transmitted to the telephone function unit 16 via an unillustrated signal line as an unillustrated audio signal, so that the user 2 has selected with the finger 8 on the touch panel 40. The music can be auditioned with the handset of the mobile phone 4.

FIG. 6 is a display screen diagram showing a display on the display surface of the touch panel of the data selling apparatus related to Example 2 of the information input / output apparatus according to the embodiment of the present invention. The second embodiment is configured as an apparatus for selling electronic ticket data for entering an event venue. The configuration is the same as that of the first embodiment of FIG. 1 except that the headphones 6 are not provided. However, when understanding the second embodiment, “music data” in FIG. 1 is read as “electronic ticket data”. In the case of the second embodiment, the audio signal output unit 58 is not necessary in the electronic ticket data sales apparatus 12.

On the other hand, the mobile phone 4 has the same hardware configuration as that of the first embodiment because only the content of received data is different. That is, the mobile phone 4 has a common configuration both for downloading music and for downloading electronic ticket data. In the second embodiment, the situation differs from the first embodiment in that the amount of information in the electronic ticket data is extremely small compared to the music data, and the time required for communication is also short. However, it may be considered that necessary data is downloaded to the mobile phone by human body communication at the moment when the touch panel is touched for data selection.

In the display screen diagram of the second embodiment shown in FIG. 6, parts corresponding to those in the first embodiment shown in FIG. 2 are given numbers in the 200s and the same numbers are given to the tenth place and the first place. And about the part which can be understood similarly to Example 1, the description in Example 1 may be used and the description in Example 2 may be simplified. FIG. 6A shows a purchase data selection screen similar to that in the first embodiment, a sports event indicated by a baseball icon 202, a travel event indicated by a small bus icon 203, a music concert indicated by a performance icon 204, etc. An event schedule such as an event is displayed in order of date together with a comment 206 such as a date. This display can also be in order of event category.

The user 2 can select an event by touching any icon with the finger 8. FIG. 6A shows a state where the finger 8 of the user 2 is touching the performance icon 204, which is detected by the function of the touch position detection unit 54 of the touch panel 38 and the selection cursor 208 is around the performance icon 204. And the user 2 is notified that the event selection is recognized by the touch panel 40. Unlike the first embodiment, in the state of FIG. 2A, only touch position detection by the touch panel function is performed, and human body communication is not performed.

Note that once the selection of the event is recognized by the electronic ticket data sales apparatus 12, the electronic ticket data sales apparatus 12 confirms that the event corresponding to the performance icon 204 has been selected even if the finger 8 is released from the display surface 38. The memory is held and the display of the selection cursor 208 is continued. When the user's 2 finger 8 touches the purchase button 212 in this state, the purchase process for the selected event is started, and the purchase screen shown in FIG. 6B is displayed. On the other hand, when the finger 8 of the user 2 touches the end button 214, the memory of the selected event is cleared and the display of the selection cursor 208 also disappears.

In FIG. 6B, a performance icon 204 corresponding to the selected event is enlarged and a detailed comment 216 such as a concert program, an event date and time, and a venue is displayed. In the second embodiment, the state shown in FIG. 6B is set, and the frequency of the publicly purchased human body communication transmission signal is set, thereby enabling human body communication. Similarly to the first embodiment, when the authentication / download / settlement button 222 is touched on the screen of FIG. 6B, a human body communication path is formed between the electronic ticket data sales apparatus 12 and the mobile phone 4 through the finger 8. When there is a response from the mobile phone 4 according to the human body communication protocol, the mobile phone icon 218 and the human body communication icon 220 are displayed. At the same time, the touch position detection unit 54 detects a touch on the authentication / download / settlement button 222, and the electronic ticket data is transmitted from the electronic ticket data selling device 12 to the mobile phone 4 including authentication of the mobile phone 4. A series of processing up to electronic settlement processing related to fee payment between the electronic ticket data selling device 12 and the mobile phone 4 is performed.

Similarly to the first embodiment, even in the state of FIG. 6B, if the authentication / download / settlement button 222 is not touched and the end button 214 is touched, the processing is canceled without entering the electronic ticket purchase. The Further, the electronic ticket data sales apparatus 12 can perform electronic ticket sales transactions with the mobile phone 4 also by the short-range communication unit 66, and can purchase and settle electronic ticket data by short-range communication regardless of human body communication. This is the same as in the first embodiment. Similarly to the first embodiment, when there is a communication response from the mobile phone 4 by the short-range communication protocol, only the mobile phone icon 218 is displayed and the human body communication icon 220 is deleted as in the first embodiment. is there.

The details of the function of the sales device control unit 46 in the second embodiment can be basically understood by replacing “music” with “event” in the flowchart of the first embodiment. In Example 2, since there is no “trial listening”, “trial listening” is simply read as “selection” for understanding. In the second embodiment, step S6 in FIG. 3 and step S40 in FIG. 4 and subsequent steps are not necessary.

FIG. 7 is a display screen diagram showing a display on the display surface of the touch panel of the data selling apparatus related to Example 3 of the information input / output apparatus according to the embodiment of the present invention. The third embodiment is configured as an image data sales apparatus. The configuration is the same as that of the first embodiment of FIG. 1 except that the headphones 6 are not provided. However, when understanding the third embodiment, “music data” in FIG. 1 is read as “image data”.

In the case of the third embodiment, “audio signal output unit 58” in the image data sales apparatus 12 is read as “sample image providing unit 58”. The sample image providing unit 58 creates a sample image having a small information amount by reducing the data amount from the main image data in the image data storage unit 56. Such a sample image takes a short time to transfer but is inferior in image quality, and is distributed free of charge as necessary. Note that the sample image providing unit 58 is not limited to the case of newly creating a sample image based on the data in the image data storage unit 56, and the image data storage unit 56 previously stores a plurality of image data with different image sizes for the same image. When prepared and stored, a function of extracting an appropriate sample image from the sample image may be used. A suitable example of the sample image prepared in advance is a so-called thumbnail image.

On the other hand, the cellular phone 4 of the third embodiment is the same as that of the first embodiment because the content of received data is different. That is, the mobile phone 4 has a common configuration for downloading music data and downloading image data. In Example 3, since the sample image has a small amount of data, the communication time is short, and the necessary data is downloaded to the mobile phone 4 by human body communication at the moment of touching the touch panel for data selection. You can think about it.

In the display screen diagram of the third embodiment shown in FIG. 7, the numbers corresponding to the first embodiment shown in FIG. 2 are numbered in the 300s, and the same numbers are given to the tenth place and the first place. And about the part which can be understood similarly to Example 1, the description in Example 1 may be used and the description in Example 3 may be simplified. FIG. 6A shows a purchase data selection screen similar to that in the first embodiment, in which sample images 302 and 304 are displayed. This display can be sorted in an appropriate order such as date order or category order.

The user 2 can select an image to be purchased by touching any sample image with the finger 8. FIG. 7A shows a state in which the finger 8 of the user 2 is touching the sample image 304, which is detected by the function of the touch position detection unit 54 of the touch panel 38 and the selection cursor 308 is around the sample image 304. And the user 2 is notified that the selection of the image is recognized by the touch panel 40.

On the other hand, the mobile phone icon 311 and the human body communication icon 313 in FIG. 7A are displayed when the mobile phone 4 is in the human body communication state through the finger 8 of the user 2 and there is a response from the mobile phone 4 according to the human body communication protocol. The As a result, the user can know that human body communication is possible. In addition, when the mobile phone icon 311 and the human body communication icon 313 are displayed and the mobile phone 4 is set to the sample image free acquisition mode, if a desired sample image is touched, the touched sample image (for example, the sample image 304) is displayed. The sample image data provided from the sample image providing unit 58 is sent to the mobile phone 4 by human body communication through the touched finger 8 and stored in the storage unit 18 free of charge. The sample image data stored in the cellular phone 4 in this way becomes access information when purchasing the main image data later.

Note that, once the image selection is recognized by the image data sales apparatus 12, the image data sales apparatus 12 stores and holds that the image corresponding to the sample image 304 has been selected even if the finger 8 moves away from the display surface 38. The display of the selection cursor 308 is also continued. When the finger 8 of the user 2 touches the purchase button 312 in this state, the purchase process of the main image data corresponding to the selected sample image is started, and the purchase screen shown in FIG. 7B is displayed. On the other hand, when the finger 8 of the user 2 touches the end button 314, the memory of the selected image is cleared and the display of the selection cursor 308 disappears.

In FIG. 7B, the sample image 304 corresponding to the selected image is enlarged and displayed. Here, when the authentication / download / settlement button 322 is touched, a human body communication path is formed again between the image data sales apparatus 12 and the mobile phone 4 through the finger 8 in the same manner as in the first embodiment, and the mobile phone is carried in accordance with the human body communication protocol. When there is a response from the telephone 4, a mobile phone icon 318 and a human body communication icon 320 are displayed. At the same time, the touch position detecting unit 54 detects a touch on the authentication / download / settlement button 322, and authentication of the mobile phone 4 is started, and then the image data is transmitted from the image data selling device 12 to the mobile phone 4 and the image is transmitted. A series of processing up to electronic settlement processing relating to fee payment between the data sales apparatus 12 and the mobile phone 4 is performed. In the third embodiment, the frequency of the transmission signal for human body communication is set to the public common frequency in both states of FIG. 7A and FIG. 7B. This is because the image data sales apparatus 12 in the third embodiment provides image data and the providing destination is limited to the mobile phone 4, so there is no need to change the frequency of the transmission signal as in the first embodiment.

As in the first embodiment, even in the state of FIG. 7B, if the authentication / download / settlement button 322 is not touched and the end button 314 is touched, the processing is performed without entering the purchase of the main image data. Canceled. In addition, the image data sales apparatus 12 can perform image sales transactions with the mobile phone 4 also by the short-range communication unit 66, and can purchase and settle image data through short-range communication regardless of human body communication. The same as in the first embodiment. As in the first embodiment, when there is a communication response from the mobile phone 4 using the short-range communication protocol, only the mobile phone icon 318 is displayed and the human body communication icon 320 is deleted as in the first embodiment. is there.

The details of the function of the sales apparatus control unit 46 in the third embodiment are basically “music” as “image”, “audio signal” as “sample image data”, and “trial listening” in the flowchart of the first embodiment. This can be understood by using “sample data free acquisition”, “headphone” as “mobile phone”, and “music data” as “main image data”. In the third embodiment, since there is no “trial listening” in the figure, it is understood that “trial listening” is simply read as “selection”. Also, step S6 and step 20 in FIG. 3 are both understood as “human body communication frequency setting”.

The third embodiment is configured as an image data sales apparatus, but the configuration of the image data sales apparatus described above is configured not only as an image sales as a business but also as a free image data exchange apparatus for private individuals. It is also possible. In this case, the configuration as the image data exchange device is preferably configured to be incorporated in a mobile phone, digital camera, image display device, etc. owned by a private person. In these implementations, a display unit such as a mobile phone, a digital camera, or an image display device is configured as a display function unit, a touch panel function unit, and a human body communication contact unit as shown in FIG.

Specifically, for example, in the case of implementation as a mobile phone, the display unit 15 of the mobile phone 4 in FIG. 1 may be configured as a touch panel and a transmission signal from the transmission / reception electrode 26 may be applied to such a touch panel. With such a configuration, for example, in the case of mobile phones, if the user touches an image displayed on the display unit of the other party's mobile phone while holding his / her own mobile phone, the other party's mobile phone is communicated by human body communication through the touched finger. Image data is transferred to your mobile phone. Also, the image of the other party's mobile phone can be touched by the other party, and he can receive the same image data transfer by touching the other party's body.

On the other hand, touch one of the displayed images with your right hand thumb while holding your mobile phone in your right hand, and touch the image display device such as an electronic photo frame with human body communication function with your left hand. Therefore, the selected image can be transferred from the mobile phone to the image display device and displayed by human body communication through the right finger touching the image. In this case, if the display surface of the image display device is configured as a display function unit, a touch panel function unit, and a human body communication contact unit as in the third embodiment, the desired on the screen specified by touching with the finger of the left hand The transferred image can also be displayed at the position.

FIG. 8 is a display screen diagram showing a display on the display surface of the touch panel of the data selling apparatus related to Example 4 of the information input / output apparatus according to the embodiment of the present invention. The fourth embodiment is configured as an electronic ticket data selling device for boarding public transportation. The configuration is the same as that of the first embodiment of FIG. 1 except that the headphones 6 are not provided. However, when understanding Example 4, it is assumed that “music data” in FIG. 1 is read as “electronic ticket data”. In the case of the fourth embodiment, the audio signal output unit 58 is not necessary in the electronic ticket data sales apparatus 12.

On the other hand, the mobile phone 4 has the same hardware configuration as that of the first embodiment because only the content of received data is different. That is, the mobile phone 4 has a common configuration for downloading music and downloading electronic ticket data. In the fourth embodiment, the situation is different from that in the first embodiment, as in the second embodiment, the information amount of the electronic ticket data is extremely small compared to the music data.

In the display screen diagram of the fourth embodiment shown in FIG. 8, parts corresponding to those in the first embodiment shown in FIG. 2 are numbered in the 400s and the same numbers are given to the tenth place and the first place. FIG. 8 is a purchase data selection screen similar to that in the first embodiment, and on the display surface 438, a commuter pass indicated by a boarding ticket icon such as a charge display 402, 404, a coupon ticket 403, and a three-month commuter pass 405 display. An icon or the like is displayed together with a route map 406 with a boarding fee as reference display information. However, on the initial screen, only the route map 406 and the authentication button 422 are displayed, and no other display is made. In this state, a transmission signal having a disclosed frequency is applied to the display surface 438, and the display surface 438 is in a standby state for human body communication. The mobile phone 4 is also set to the same frequency and is in a human body communication standby state. The electronic ticket data selling device 12 of the fourth embodiment can also function as a normal ticket vending machine, and when a considerable amount of money is inserted into the money / banknote insertion unit 407, a ticket that can be purchased with the amount inserted. When one of the icons is touched, the corresponding paper ticket is discharged from the normal ticket discharge unit 409.

When purchasing an electronic ticket on the display surface 438 in FIG. 8, the user 2 first touches the authentication button 422 with the finger 8. As a result, a human body communication path is formed between the electronic ticket data sales apparatus 12 and the mobile phone 4 through the finger 8, and when there is a response from the mobile phone 4 according to the human body communication protocol, a mobile phone icon 418 and a human body communication icon 420 are displayed. Is done. Then, it is authenticated whether or not the mobile phone 4 has a payment qualification through human body communication through the touched authentication button 422. If OK, a ticket icon 403, such as a ticket icon 402 up to a payable amount, And a commuter pass icon 405. Such an authentication result is stored in the electronic ticket data sales apparatus 12 even if the finger 8 is released from the authentication button 422. This memory can be canceled by touching the cancel button 414, and if the cancel button 414 is touched, the boarding ticket icon 402 etc. disappears and the screen returns to the initial screen.

By touching one of the ticket icons 402 and the like with the authentication result stored, the ticket data to be purchased can be selected. FIG. 8 shows a state where the finger 2 of the user 2 touches the boarding ticket icon 404, which is detected by the function of the touch position detection unit 54 of the touch panel 38 and the selection cursor 408 is displayed around the performance icon 204.

Payment is made with the data sales apparatus 12. Therefore, the display of the selection icon 408 is also a display that informs the user 2 of the completion of the acquisition and settlement of such electronic ticket data. The electronic ticket data stored in the mobile phone 4 is authenticated by the short-range communication between the short-range communication unit 20 of the mobile phone and the short-range communication unit provided in the ticket gate when the ticket is passed, and the user 2 opens the ticket gate. Allow to pass. This short-range communication function is a normal configuration that is already widely used in ticket gates. When the ticket gate is provided with a human body communication function, it is possible to perform the ticket gate by human body communication through the transmission / reception electrode 26. In this case, the user touches a predetermined part of the ticket gate and passes the ticket gate.

Details of various elements in the function of the sales apparatus control unit 46 in the fourth embodiment can be understood by obtaining corresponding elements in the flowchart relating to the first embodiment. In Example 4, it should be noted that the touch for authentication and the touch for electronic ticket acquisition and electronic payment are performed separately. However, the human body communication for “trial listening” in the first embodiment (however, the case where the trial listening is performed by the mobile phone 4 applies mutatis mutandis) is changed to the human body communication for “authentication” in the fourth embodiment. The human body communication for “data purchase” can be applied to the human body communication for “electronic ticket data purchase” in the fourth embodiment. In the fourth embodiment, the frequency of the transmission signal used in the human body communication between the mobile phone 4 and the electronic ticket data selling device 12 is the same for both “authentication” and “purchasing electronic ticket data”. It shall be read as a thing to understand the flowchart.

FIG. 9 is a display screen diagram showing a display on the display surface of the touch panel regarding Example 5 of the information input / output device according to the embodiment of the present invention. Example 5 is configured as an automatic teller machine of a bank. The configuration is the same as that of the first embodiment of FIG. 1 except that the headphones 6 are not provided. However, when understanding the fifth embodiment, it is assumed that “music data sales apparatus” or “sales apparatus” in FIG. 1 is understood as “automatic teller machine” and “music data” is read as “accounting data”. In the case of the fifth embodiment, the audio signal output unit 58 is not necessary in the electronic ticket data sales apparatus 12.

On the other hand, the mobile phone 4 has the same hardware configuration as that of the first embodiment because only the content of received data is different. That is, the mobile phone 4 has a common configuration both in downloading music and exchanging cash data with the bank. In the fifth embodiment, the situation is different from that in the first embodiment, as in the case of the second embodiment and the fourth embodiment, the amount of information in the balance data is extremely small compared to the music data.

In the display screen diagram of the fifth embodiment shown in FIG. FIG. 9 shows an operation screen in the automatic teller machine, and a remittance screen is shown on the display surface 538 as an example. Specifically, the transaction request data display unit 550 displays the names of the sender and recipient, the bank name, the branch name, the account number, and the amount of money to be sent.

FIG. 11 is a basic flow of the television control unit 46 of the television 12 in the sixth embodiment. The flow starts when the main switch is turned on and power is supplied to the television 12. When the flow starts, a broadcast television program screen received by the tuner is displayed in step S122. Next, in step S124, it is checked whether the mail order program is being broadcast. If it is being broadcast, it is checked in step S126 whether the product selection screen is being displayed. If not, the process proceeds to step S128.

In step S128, it is checked whether or not the operation for reproducing the product selection screen stored in the previous mail order program is instructed by the TV remote controller or the like. If it is detected that the reproduction instruction is in progress, the process proceeds to step S130. move on. In step S130, the display on the display surface 38 is switched from the broadcast screen received by the tuner to the product selection screen based on the stored information, and the process proceeds to step S132. On the other hand, when the broadcast product selection screen is being displayed in step S126, the process also proceeds to step S132. In either case, in step S132, the touch panel function is turned on, and the process proceeds to step S134.

In step S134, in conjunction with the display screen 638 becoming the product selection screen display, a transmission signal having a disclosed frequency is automatically applied to the display surface 638 to enter a standby state for human body communication. In step S136, it is checked whether or not the touch panel 40 on the display surface 38 is touched. When a touch on the touch panel is detected, a touch position detection process is performed in step S138. In step S140, it is checked whether the selection display screen is being broadcast. If it is broadcast, the process proceeds to step S142, and the product data related to all the products in the still screen for selection display received by the tuner is stored in the product data storage unit 56. Furthermore, in step S144, based on this stored data, the product selection screen display is continued regardless of the program progress, and the process proceeds to step S146. On the other hand, if it is not detected in step S140 that the selection display screen is being broadcast, it means that the selection display screen is displayed based on the stored information, and the process directly proceeds to step S146.

In step S146, touch handling processing based on the touch position detected in step S138 is performed. Details thereof will be described later. In step S146, it is checked whether the touch on the panel is a touch on the end button. If the end button is touched, the process proceeds to step S150. In step S150, it is checked whether the main switch is turned off and the power supply to the television 12 has been cut off. If it is detected that the power supply has been cut off, the flow ends.

If no touch on the panel is detected at step S136, the process proceeds to step S152 to check whether the displayed selection display screen is being broadcast. If the program is being broadcast, the flow returns to step S124 so as to be able to cope with display changes other than the product selection screen based on the program progress. On the other hand, if it is not detected that the selection display screen displayed in step S152 is being broadcast, this means that the display is based on storage, and the process returns to step S136. Steps S136 and S152 are repeated until a touch on the panel is detected, and the touch is awaited. Also, if the touch of the end button is not detected in step S148, the process proceeds to step S152. In this case, since there is only a display based on the memory, the process proceeds to step S136. Unless detected, step S136 to step S148 and step S152 are repeated, corresponding to various touches on the panel while continuing to display the selection display screen based on the memory.

By the way, if it is not detected in step S128 that the selection screen playback instruction is in progress, it means that the display state is a normal television program in which the product selection screen is not displayed by either program progress or playback. In step S154, the touch panel function is turned off, and in step S156, application of a transmission signal to the transmission / reception electrode 62 is automatically stopped so that human body communication is not performed.

If the end button touch is not detected, the process proceeds to step S178, and it is checked whether any of the product icons is touched. When the touch of the product icon is detected, the process proceeds to step S180, and it is checked whether or not the browsing mode is set. If it is the browsing mode, the process proceeds to step S184, and the display is changed to the product selection screen display in FIG. 10A as the product detail display screen in FIG. On the other hand, when the browsing mode setting is not detected in step S180, the process directly proceeds to step S186.

In step S186, it is checked whether the URL acquisition mode is set. If it is the URL acquisition mode, the process proceeds to step S188, where URL data is output to the mobile phone 4 by human body communication through the touching finger, and the process proceeds to step S190. On the other hand, when the URL acquisition mode setting is not detected in step S186, the process directly proceeds to step S190. In step S190, it is checked whether the telephone number acquisition mode is set. If it is the telephone number acquisition mode, the process proceeds to step S192, where the telephone number data is output to the mobile phone 4 by human body communication through the touched finger, and the flow ends. On the other hand, if the URL acquisition mode setting is not detected in step S190, the flow is immediately terminated. Also, when no touch on any product icon is detected in step S178, the flow is immediately terminated.

On the other hand, when it is detected in step S162 that the display surface 638 is in the display state of the product detail display screen, the process proceeds to step S194. In step S194, the product information display portion on the product detail display screen has been touched. Check it out. When a touch is detected, the process proceeds to step S196, where detailed product data is output to the mobile phone 4 by human body communication through the touching finger, and the process proceeds to step S198. In step S198, it is checked whether or not the touched position is a part of the product itself. If applicable, the process proceeds to step S20, and an enlarged image of the part being touched is displayed in an overlapping manner, and the process proceeds to step S202. On the other hand, if it is not detected in step S198 that the touched position is a product part, the process directly goes to step S202 because the touch is on the information part. Furthermore, also when the touch to a merchandise information display part is not detected by step S194, it transfers to step S202 directly.

In step S202, it is checked whether or not the “return” button on the product detail display screen has been touched. If applicable, the process proceeds to step S204, and the display is changed from the product detail display screen in FIG. The display is returned to the product selection screen display in A) and the flow is ended. In step S204, the product selection screen display is set to the browsing mode. Note that step S176 in FIG. 12 is provided to quickly end the touch handling process when it is detected that the end button has been touched. In FIG. 11, the touch of the end button is further detected in step S148 after the touch handling process. In this case, even if the same thing is detected twice, there is no problem in the flow of the flow.

FIG. 13 is a basic flow related to cooperation with the television 12 in the mobile phone control unit 14 of the mobile phone 4 in the sixth embodiment. In FIG. 13, functions such as normal voice calls and mails that are inherent to mobile phones are omitted, and calls and Internet functions are illustrated only in the case of cooperation with the television 12. The flow starts when the main switch is turned on and power is supplied to the mobile phone. When the flow starts, a cellular phone startup process is performed in step S212. In step S214, it is checked whether an operation for setting activation of the human body communication function has been performed. If no human body communication setting operation is detected, the flow proceeds to step S250, and if power off by the main switch is not detected here, the flow returns to step S214. In this manner, unless the human body communication setting operation is performed in step S214, steps S214 and S250 are repeated. If there is a normal operation of the mobile phone during this time, a flow related to the operation is executed. . In FIG. 13, illustration and description of the steps relating to these are omitted.

When a human body communication setting operation is detected in step S214, the process proceeds to step S216, and the frequency for human body communication with the registered television 12 is set. Further, in step S218, the television 12 is authenticated by short-range communication. If the authentication is OK, a signal for human body communication is applied to the transmission / reception electrode 26 in step S220 to enter a human body communication standby state. Next, in step S224, it is checked whether the URL has been acquired through human body communication. If the URL acquisition can be confirmed, the process proceeds to step S226 to automatically set the Internet mode. Further, the URL acquired in step S228 is automatically set as an access destination, and a connection to a mail order WEB site is prepared. When the authentication of the television 12 is NG in step S218, the process proceeds to step S252, and after displaying that the human body communication setting is prohibited, the process proceeds to step S250. In this way, in human body communication, an information provider is authenticated so that malicious data is not taken into the mobile phone 4 due to careless human contact.

If the authentication of the television 12 is OK in step S218 and the connection to the mail-order WEB site is prepared by step S228 as described above, the connection operation to the WEB site is performed within a predetermined time in step S230. Check if it has been done. When a connection operation is detected, the process proceeds to step S232, where a product purchase process by mail order according to the guidance on the WEB site is performed, and the process proceeds to step S234. On the other hand, when the connection operation within the predetermined time is not detected in step S230, the process proceeds to step S236, where the URL is automatically stored, and the process proceeds to step S234. As a result, the purchase process can be performed after reexamination at a later date. In addition, when acquisition of URL is not detected by step S224, it transfers to step S234 directly.

In step S234, it is checked whether or not the telephone number has been acquired through human body communication, and if the telephone number acquisition can be confirmed, the process proceeds to step S238 to automatically set a dial for product purchase by mail order based on the acquired telephone number. . In step S240, it is checked whether a call operation has been performed within a predetermined time based on the set telephone number.

On the other hand, if a call operation within a predetermined time is not detected in step S240, the process proceeds to step S246, where the telephone number is automatically stored in the telephone directory of the mobile phone 4, and the process proceeds to step S244. As a result, a phone call for purchase can be made after review at a later date. In addition, when acquisition of a telephone number is not detected by step S234, it transfers to step S244 directly.

In step S244, it is checked whether a human body communication end operation has been performed. When the human body communication end operation is detected, the process proceeds to step S248, the application of the human body communication signal to the electrode is stopped, and the process proceeds to step S250. On the other hand, if a human body communication end operation is not detected in step S244, the process returns to step S224. Thereafter, unless a human body communication end operation is detected in step S244, steps S224 to S244 are repeated to correspond to information acquisition by human body communication. .

The seventh embodiment is configured as a mail order device in which a street display device and a mobile phone cooperate. The street display device according to the seventh embodiment can be specifically configured as a large screen display device attached to a street show window, an electronic paper advertisement posted on the street, or the like. Since the configuration is the same as that of the sixth embodiment except that the display device is changed from a television to a street display device, description will be made with reference to FIGS. 1 and 10. However, when understanding Example 7, it is assumed that “music data sales device” or “sales device” in FIG. 1 is understood as “street display device” and “music data” is read as “product data”. Also in the case of the seventh embodiment, the audio signal output unit 58 is not necessary in the street display device 12. In the street display device 12, it is assumed that the display data of the mail-order products is received by the short-range communication unit 66 of FIG. 1 or an appropriate wireless / wired communication means not shown in FIG. Further, since the street display device is dedicated to displaying product information, the end button 614 provided for returning to the display as the TV program progresses in FIG. 10A is unnecessary.

In the seventh embodiment, a transmission signal having a disclosed frequency is applied to the display surface 638 of the street display device 12 during a person's passage time except for midnight, and the apparatus is in a standby state for human body communication. Such control based on time is performed by the street display device control unit 46 having a built-in clock function. On the other hand, the mobile phone 4 side is set to the same frequency by being set in the mail order mode, and is in a human body communication standby state. When both are in a standby state and the browse button 612 is touched while the menu icon is displayed on the display surface 638, the browse button 612 is displayed in FIG. Thus, the display state is surrounded by a thick frame. Since the operation in the “browsing” state is the same as that in the sixth embodiment, the description thereof is omitted. Further, the operation when the URL button 615 is touched and the operation when the TEL button is touched are the same as those in the sixth embodiment, and thus description thereof is omitted.

In the seventh embodiment, when the street display device 12 is configured as a large screen display device attached to the show window, the product displayed on the display surface 638 is made to correspond to the product actually displayed in the show window. The same product number as the product in the window is attached, or the product icons on the display surface 638 can be arranged in a layout corresponding to the display arrangement of the show window. On the other hand, when the street display device 12 is configured as an electronic paper advertisement, it takes a simpler configuration and eliminates an enlarged image as shown in FIG. Only the product icon 602 can be displayed. Since the function in this case is specialized for obtaining a URL or a telephone number through human body communication, it is not necessary to display not only the end button 614 but also the browse button 612. Further, the product icon 602 can be an actual product photo instead of a symbol. In this case, the product icon 602 can be displayed as a large product photo by displaying the electronic paper advertisement on a large screen as compared with the mail order using only the display unit 15 of the mobile phone 4. Purchasing consideration based on this becomes possible. Note that the URL and telephone number acquisition based on the touch on the electronic paper advertisement in Example 7 are not only mail-order sales, but generally when viewing the electronic paper advertisement and accessing the WEB to acquire detailed information or by telephone When making inquiries, it is useful to save time for notes or manual entry.
