Description

The present invention relates to a communication system, a communication terminal, communication method, a 及 Beauty receiving method.

  In the communication means using the communication by the conventional telephone network and the mobile phone network, communication is mainly achieved by transmitting and receiving voice information. In recent cellular phones, a camera is provided to make a videophone call and to transmit and receive not only audio information but also video information, thereby diversifying communication (for example, Patent Document 1). A video phone is a device that integrates a telephone, a camera, and a receiver. It is a system that displays the other party's screen on the receiver and looks at the face in the same way as a TV. Say. The basic principle of the video system is the same as that of television. The camera itself is imaged by a camera, and is decomposed into image signals and transmitted. The image signal is received by the receiver, and the other party is displayed on the display. The voice system is the same principle as a normal telephone. In order to reduce the transmission cost, a method of greatly compressing the band of the video signal and the audio signal by digital technology is used. As a result, if there is a bandwidth equivalent to one ordinary telephone line (64 kilobits / second), almost practical communication quality can be obtained. Many videophones using the Internet or mobile phones are transmitted at 64 kilobits / second.

  The control unit 250 of the communication terminal 2 supplies a drive signal to the tactile sensation providing unit 240 based on the received data related to the tactile sensation. The tactile sensation providing unit 240 generates vibration based on the drive signal supplied from the control unit 250 and presents a tactile sensation. The operator of the communication terminal 2 can perceive the tactile sensation received from the communication terminal 1 by touching the communication terminal 2.

  Preferably, the control unit 250 of the communication terminal 2 displays a tactile sensation locus on the display unit 230 based on the tactile sensation data. For example, when the tactile sensor 120 detects a slide operation from the upper right to the lower left by the operator in the communication terminal 1, the display unit 230 of the communication terminal 2 displays a locus corresponding to the slide operation (FIG. 4B). .

  In FIG. 4B, when the touch sensor 120 or the touch sensor 220 detects contact at a predetermined position by the operator of the communication terminal 1 or the communication terminal 2, switching between the touch transmission mode and the touch reception mode is performed.

  In FIG. 4B, when the tactile sensor 120 detects contact at the lower right portion of the display unit 130 of the communication terminal 1, that is, at the position of the own face image, the control unit 150 of the communication terminal 1 Switch to the touch reception mode. The control unit 150 notifies the communication terminal 2 of mode switching when switching modes. Based on the notification, the control unit 250 of the communication terminal 2 switches the communication terminal 2 from the touch reception mode to the touch transmission mode.

  4B, when the tactile sensor 220 detects contact at the lower right portion of the display unit 230 of the communication terminal 2, that is, the position of the own face image, the control unit 250 of the communication terminal 2 Switch from touch reception mode to touch transmission mode. The control unit 250 notifies the communication terminal 1 of mode switching when switching modes. Based on the notification, the control unit 150 of the communication terminal 1 switches the communication terminal 1 from the touch transmission mode to the touch reception mode.

  When the control unit 250 of the communication terminal 2 switches the communication terminal 2 from the touch reception mode to the touch transmission mode, when the tactile sensor 220 detects contact by the operator, the control unit 250 detects the tactile sensor 220 of the communication terminal 2. The data relating to the tactile sensation is acquired from the data and the data relating to the tactile sensation is transmitted to the communication terminal 1 (FIG. 4C).

  Preferably, the control unit 150 of the communication terminal 1 displays a tactile sensation locus on the display unit 130 based on tactile sensation data. For example, when the tactile sensor 220 detects a slide operation from the upper right to the lower left by the operator in the communication terminal 2, the display unit 130 of the communication terminal 1 displays a locus corresponding to the slide operation (FIG. 4C). .

  The control unit 150 of the communication terminal 1 supplies a drive signal to the tactile sensation providing unit 140 based on the received data related to the tactile sensation. The tactile sensation providing unit 140 generates vibration based on the drive signal supplied from the control unit 150 and presents a tactile sensation. In this way, the operator of the communication terminal 1 can perceive the tactile sensation received from the communication terminal 2 by touching the communication terminal 1.

  When the tactile sensor 120 of the communication terminal 1 and the tactile sensor 220 of the communication terminal 2 do not detect contact for a certain period of time, the control unit 150 of the communication terminal 1 and the control unit 250 of the communication terminal 2 respectively communicate with the communication terminal 1 and the communication. The mode of the terminal 2 is switched to the normal mode (FIG. 4 (d)).

  Next, the operation of the tactile communication system according to the present invention will be described with reference to the flowchart shown in FIG. In the flowchart shown in FIG. 5, it is assumed that the communication terminal 1 and the communication terminal 2 are communicating in advance by voice call.

  First, the control unit 150 of the communication terminal 1 determines whether to switch to the touch transmission mode depending on whether or not the tactile sensor 120 has detected a long press due to an operation by the operator (step S1). If it is determined to switch to the touch transmission mode, the process proceeds to step S2. If it is determined not to switch to the touch transmission mode, step S1 is repeated.

  Subsequently, the control unit 150 transmits a mode switching notification to the communication terminal 2 by the communication unit 110 via the network 3 (step S2). Then, the control unit 150 switches the communication terminal 1 from the normal mode to the touch transmission mode (step S3). When receiving the mode switching notification, the control unit 250 of the communication terminal 2 switches the communication terminal 2 from the normal mode to the touch reception mode (step S4).

  Subsequently, the control unit 150 of the communication terminal 1 determines whether or not the tactile sensor 120 has detected contact with a contact object (step S5). When the contact by the contact object is detected, the control unit 150 acquires tactile sensation data from the tactile sensor 120 and transmits the tactile sensation data to the communication terminal 2 via the network 3 by the communication unit 110 (step S6). When the communication unit 210 of the communication terminal 2 receives the data related to the tactile sensation (step S7), the control unit 250 of the communication terminal 2 supplies a drive signal to the tactile sensation providing unit 240 based on the data related to the tactile sensation. The tactile sensation providing unit 240 generates a vibration based on the drive signal supplied from the control unit 250 and presents a tactile sensation (step S8). When contact by a contact object is not detected in step S5, step S6 to step S8 are skipped and the process proceeds to step S9.

  Subsequently, the control unit 250 of the communication terminal 2 determines switching to the touch transmission mode depending on whether or not the tactile sensor 220 has detected a contact at a predetermined position due to an operation by the operator (step S9). When the tactile sensor 220 detects contact at a predetermined position by the operation of the operator, the control unit 250 transmits a mode switching notification to the communication terminal 1 by the communication unit 210 via the network 3 (step S10). On the other hand, if the contact at the predetermined position by the operation of the operator is not detected in step S9, the process proceeds to step S11.

  Subsequently, the control unit 150 of the communication terminal 1 determines whether or not the tactile sensor 120 has detected a contact at a predetermined position by the operation of the operator, or whether or not a notification of mode switching has been received from the communication terminal 2. Thus, switching to the touch reception mode is determined (step S11).

  When the contact at the predetermined position due to the operation of the operator is not detected in step S11 and the mode switching notification is not received from the communication terminal 2, the control unit 150 indicates that no operation has been performed on the tactile sensor 120 for a certain period of time. It is determined whether or not (step S12). If the fixed time has not elapsed, the process returns to step S5. On the other hand, when the predetermined time has elapsed, the control unit 150 transmits a mode switching notification to the communication terminal 2 by the communication unit 110 via the network 3, and switches the communication terminal 1 from the touch transmission mode to the normal mode. . Further, the control unit 250 of the communication terminal 2 switches the communication terminal 2 from the touch reception mode to the normal mode by the notification of the mode switching (step S13), and the process ends.

  In step S <b> 11, when a contact at a predetermined position due to an operation by the operator is detected or a mode switching notification is received from the communication terminal 2, the control unit 150 sends a mode switching notification via the network 3 to the communication unit 110. Is transmitted to the communication terminal 2 (step S14). Then, the control unit 150 switches the communication terminal 1 from the touch transmission mode to the touch reception mode (step S15). On the other hand, the control unit 250 of the communication terminal 2 switches the communication terminal 2 from the touch reception mode to the touch transmission mode (step S16).

  Subsequently, the control unit 250 of the communication terminal 2 determines whether or not the tactile sensor 220 has detected contact with a contact object (step S17). When the contact by the contact object is detected, the control unit 250 acquires tactile sensation data from the tactile sensor 220 and transmits the tactile sensation data to the communication terminal 1 by the communication unit 210 via the network 3 (step S18). When the communication unit 110 of the communication terminal 1 receives the data related to the tactile sensation (step S19), the control unit 150 of the communication terminal 1 supplies a drive signal to the tactile sensation providing unit 140 based on the data related to the tactile sensation. The tactile sensation providing unit 140 generates vibration based on the drive signal supplied from the control unit 150 and presents a tactile sensation (step S20). When the contact by the contact object is not detected, step S18 to step S20 are skipped and the process proceeds to step S21.

  Subsequently, the control unit 150 of the communication terminal 1 determines switching to the touch transmission mode depending on whether or not the tactile sensor 120 has detected a contact at a predetermined position by the operation of the operator (step S21). When the tactile sensor 120 detects contact at a predetermined position by the operation of the operator, the control unit 150 transmits a mode switching notification to the communication terminal 2 by the communication unit 110 via the network 3 (step S22). On the other hand, if the contact at the predetermined position by the operation of the operator is not detected in step S21, the process proceeds to step S23.

  Subsequently, the control unit 250 of the communication terminal 2 determines whether the tactile sensor 220 has detected a contact at a predetermined position by the operation of the operator, or whether a notification of mode switching has been received from the communication terminal 2. Thus, switching to the touch reception mode is determined (step S23).

  When the contact at the predetermined position due to the operation of the operator is not detected in step S23 and the mode switching notification is not received from the communication terminal 1, the control unit 250 determines that the tactile sensor 220 has not been operated for a certain period of time. It is determined whether or not (step S24). If the predetermined time has not elapsed, the process returns to step S17. On the other hand, when the predetermined time has elapsed, the control unit 250 transmits a mode switching notification to the communication terminal 1 by the communication unit 210 via the network 3, and switches the communication terminal 2 from the touch transmission mode to the normal mode. . Further, the control unit 150 of the communication terminal 1 switches the communication terminal 1 from the touch reception mode to the normal mode based on the mode switching notification (step S25), and the process ends.

  When contact at a predetermined position due to an operation by the operator is detected in step S23 or a mode switching notification is received from the communication terminal 1, the control unit 250 sends a mode switching notification via the network 3 to the communication unit 210. Is transmitted to the communication terminal 1 (step S26). Then, the control unit 250 switches the communication terminal 2 from the touch transmission mode to the touch reception mode (step S27). The operation of the communication terminal 2 after switching the touch reception mode is the same as the operation after step S7. On the other hand, the control unit 150 of the communication terminal 1 switches the communication terminal 1 from the touch reception mode to the touch transmission mode (step S28). The operation of the communication terminal 1 after switching the touch reception mode is the same as the operation after step S5.

  As described above, according to the present invention, data related to the tactile sensation of the communication terminal 1 and the communication terminal 2 is communicated via the network 3, and the communication terminal 1 and the communication terminal 2 are related to the tactile sensation of the communication terminal 2 and the communication terminal 1, respectively. Since the tactile sensation presenting unit 140 and the tactile sensation presenting unit 240 present the tactile sensation based on the above, the communication regarding the tactile sensation, which is information other than the audio information and the video information, can be transmitted, thereby further facilitating communication.

  According to the present invention, when the control unit 150 of the communication terminal 1 is transmitting data related to the tactile sensation, the communication terminal 1 transmits the data related to the tactile sensation to the communication terminal 2 in order to stop receiving the data related to the tactile sensation. The data relating to the desired tactile sensation can be transmitted to the communication terminal 2 without unintended noise being mixed into the data relating to the tactile sensation.

  According to the present invention, when the control unit 150 of the communication terminal 1 is receiving data related to the tactile sensation, the communication terminal 1 receives from the communication terminal 2 in order to stop transmitting the data related to the tactile sensation to the communication terminal 2. Data relating to a desired tactile sensation can be received from the communication terminal 2 without unintentional noise being mixed into the tactile sensation data.

  The noise will be specifically described below. It is assumed that the communication terminal 1 can transmit the tactile sensation data to the communication terminal 2 while the communication terminal 1 is receiving the tactile sensation data from the communication terminal 2. Then, when the operator of the communication terminal 1 touches the screen in order to feel the tactile sensation received, the touch becomes an input of the tactile sensation in the communication terminal 1, and unintended tactile sensation data is transmitted from the communication terminal 1 to the communication terminal 2. The problem of end up occurs.

  In addition, the tactile sensation providing unit 140 of the communication terminal 1 vibrates due to the tactile sensation data received from the communication terminal 2. The problem of being transmitted to the terminal 2 occurs. In particular, in the case of a digital communication device such as a mobile phone, since the signal is digitized and compressed, it takes time to decode. For this reason, there is a risk of echo due to a time lag. Furthermore, since the tactile sensor 120 and the tactile sensation providing unit 140 are arranged in close proximity, they are influenced by each other. Therefore, it is strongly influenced by howling and echo phenomenon compared to voice.

  In addition, the amount of information of speech is different depending on the person's voice quality (speaking method, pitch of sound (pitch, frequency), combination of vowels and consonants, formant (property of frequency peak shifting with time), etc.) It is possible to recognize the difference between one's own voice and another person even if talking at the same time, whereas the tactile sensation is conveyed only by vibration of the communication terminal 1 or the communication terminal 2. Compared to this, it is less affected by noise.

  As described above, when the communication terminal 1 and the communication terminal 2 transmit or receive the tactile sensation at the same time, it becomes difficult to recognize which vibration is the received tactile sensation. In addition, due to the tactile sensation as described above, it becomes more difficult to distinguish between tactile sensation and noise when howling or echo occurs.

  Therefore, according to the configuration of the present invention, when the communication terminal 1 is transmitting data relating to the tactile sensation without the communication terminal 1 and the communication terminal 2 simultaneously transmitting or receiving the tactile sensation, Stop receiving. Further, when the communication terminal 1 is receiving data related to the tactile sensation, the transmission of the data related to the tactile sensation to the communication terminal 2 is stopped. Therefore, the above-described problem of howling and echo phenomenon can be prevented.

  In step S7, the control unit 250 of the communication terminal 2 supplies a drive signal to the tactile sensation providing unit 240 based on the tactile sensation data. The drive signal at this time is faithful to the tactile sensation in the communication terminal 1 in the communication terminal 2. It is not limited to what is reproduced. For example, the control unit 250 may supply the tactile sensation providing unit 240 with a drive signal obtained by processing the received tactile sensation data. Specifically, the control unit 250 may supply a drive signal that increases the amplitude in the received tactile sensation data and drives the tactile sensation providing unit 240 with the increased amplitude.

  Similarly, in step S <b> 19, the control unit 150 of the communication terminal 1 supplies a drive signal to the tactile sensation providing unit 140 based on the tactile sensation data. It is not limited to what is faithfully reproduced. For example, the control unit 150 may supply the tactile sensation providing unit 140 with a drive signal obtained by processing the received tactile sensation data. Specifically, the control unit 150 may supply a drive signal that increases the amplitude in the received tactile sensation data and drives the tactile sensation providing unit 140 with the increased amplitude.

  In the present embodiment, the communication terminal 1 and the communication terminal 2 have shown an example in which communication is performed via the network 3, but the present invention is not limited to this. For example, the communication terminal 1 and the communication terminal 2 do not pass through the network 3, that is, near the RFID, infrared communication (IrDA), Bluetooth (registered trademark), Zigbee (registered trademark) (IEEE 802.15.4), IEEE 802.11, and the like. You may make it transmit the video telephone, the data regarding a contact, and the data regarding a tactile sensation also by distance wireless communication.

  In the present embodiment, the communication terminal 1 and the communication terminal 2 transmit and receive the tactile sensation data based on the tactile sensation data detected by the tactile sensor 120 and the tactile sensor 220, respectively. It is not limited to. For example, the communication terminal 1 and the communication terminal 2 may transmit and receive a predetermined vibration pattern associated with the tactile sensation data detected by the tactile sensor 120 and the tactile sensor 220 and information indicating the vibration pattern.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, the functions included in each means, each step, etc. can be rearranged so that there is no logical contradiction, and a plurality of means, steps, etc. can be combined or divided into one. .
