A technique for transmitting and receiving data by e-mail or the like is well known.
As a means for persons with disabilities to communicate via telephone lines, telephone communication devices TDD / TTY developed for persons with hearing impairments have become widespread in the United States. In this method, character information input from a typewriter is transmitted via a telephone line, and characters are displayed on the liquid crystal display device on the receiving side. In addition, there is an example in which the TDD / TTY is modified and the receiving unit of the liquid crystal display device is replaced with a braille display ("Possibility and problem of using a computer network by deafblind people" IEICE Technical Report E
T97-79).

[0003] On the other hand, finger braille is known as one of the means for a deafblind person who has impaired sight and hearing to take daily communication. As a device for transmitting information in a finger braille pattern, a method of presenting character information by stimulating a stimulating element provided on the finger pad or back of six fingers (hereinafter, a six-finger braille method) has been reported. ("Braille information transmission device", Japanese Patent Laid-Open No. 10-105048,
"New Braille Transmission Method by Passive Tactile Sensing", Journal of the Institute of Image Information and Television Engineers, VOL52, 98-4, "Study of Optimal Stimulation Mode for Finger Braille Display", Transactions of the Institute of Electronics, Information and Communication Engineers (A), VOL. J81-A, No 9. 1

There is a problem that cannot be performed. Further, since there is no function having a function of notifying the user of the start / end of the conversation or the change of the speaker / listener, it is difficult to form a form such as a normal verbal conversation.

In a type in which the receiving unit of the liquid crystal display device is replaced with a braille display by modifying the TDD / TTY, it is possible to form a conversation form close to real time, but it is possible to realize real time conversation in the same manner as verbal conversation. It is difficult to tell. In addition, this type is not a form that expresses unique listening, reunion, or restatement in oral conversation.

[0007] Furthermore, in the above-mentioned system using a braille pin display, a handicapped person who has learned small-sized braille can be used, but the sense of a fingertip is limited, and a handicapped person who cannot read braille is used. There are issues such as being unable to do so.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to enable persons with disabilities in communication, including deafblind persons, to eliminate communication barriers caused by various disabilities, An object of the present invention is to provide a communication device and a communication method capable of realizing remote communication between a person with a disability and a healthy person, and a recording medium recording a program of the method.

Next, a method for performing remote communication using the communication device according to the present invention including the six-finger braille terminals 5 and 15 will be described. When explaining remote communication, tactile stimuli that inform the user of the state necessary for conversation, such as starting and ending a conversation, acquiring the right to speak (speaker change), joining, re-listening, and correcting the speaker's remarks, are used before. In addition to the tactile stimulus corresponding to the character information based on the "6 finger braille method" described above, the stimulus is applied as stimuli at various timings unique to the present invention (see FIG. 6).

FIG. 5 is a flowchart showing a protocol and a method for realizing remote communication using the communication device according to the present invention. FIG. 6 is an explanatory diagram exemplifying types of stimuli at the various timings for transmitting a state of conversation. FIG. 7 is a schematic explanatory view illustrating an example of a method of driving the stimulus pins of the six-fingered Braille terminals 5 and 15, and FIG. is there.

Hereinafter, the communication method will be sequentially described with reference to FIGS. 1 and 6 to 8 in accordance with the flowchart of FIG.

The sender, that is, the sender (in this embodiment, the user of the left block in FIG. 1) uses the braille input keys 21 to 26 of the six-finger braille terminal 5 or the ten keys of the keyboard 3. Input the telephone number of the transmission destination (S500). The character data for conversation coded by the voice modem 2 is transmitted and detected by the computer 11 on the receiving side. Thereby, the computer 11 puts the transmitter 20 in the transmission state.

When the wearable vibration presenter 19 receives a weak radio wave from the transmitter 20, it displays a ringing vibration by, for example, driving a vibration motor (S504), thereby presenting an incoming call to the receiver (S506). . During the transmission of the radio wave, the sender (user of the computer 1) receives a stimulus signal (FIG. 6) of the DISP1 by the six-finger braille terminal 5 on the transmission side.
Is presented to the user (S501) to notify that the telephone is being called (S503).

Here, as shown in FIG. 7, the stimulus pins 21a, 21b, 2 arranged in the lateral direction of the Braille input key unit 21, for example, as shown in FIG.
1c is simultaneously driven at a presentation time t at respective timings corresponding to the respective conversation states to be conveyed. The timing corresponds to the vibration frequency f, the presentation time t,
The pause time t0 and the number of repetitions of the cycle T are set to the values illustrated in FIG. 6, and the delay times within one finger and between the six fingers are also set to the values illustrated in FIG. Thereby, various stimulation conditions are transmitted to the six fingers to convey the state of conversation.

For example, in the case of the DISP 1 during the telephone call, FIG. 6 shows both the receiving side and the transmitting side, and the vibration of the constant frequency f1 is given for 3 seconds, and the pause time t for 1 second.
At o, the six fingers are driven at the same time (no delay between the six fingers) until there is a response on the receiving side. This stimulus signal is transmitted using the six-finger braille terminals 5, 15 and the wearable vibration presenters 9, 19.

Returning to FIG. 5, when the receiving computer 11 detects an incoming call, the computers 1 and 11 transmit information such as their names and telephone numbers registered in advance to each other (S507). . Further, the presenting unit of the six-finger braille terminals 5, 15 on both the transmitting and receiving sides provides
The stimulus signal of ISP2 (FIG. 6) is presented (S509).
Thus, both users are notified that the communication partner is ready for confirmation.

Information such as the communicated user name and telephone number is temporarily stored in a memory buffer of each of the computers 1 and 11, and is output to the 6-finger Braille terminals 5 and 15 so that the information of the communication partner can be used by both users. (S510, S5
11). When the communication partner can be confirmed, both the transmitting and receiving users press the switch 30 of the six-finger braille terminal 5, 15 or the carriage return key or the enter key (not shown) of the keyboard 3, 13. I do.

In step S513, the sender and receiver names and the mode are confirmed, and the switch 30 or the carriage return
When detecting depression of the key or the enter key, the computers 1 and 11 transmit a "confirmation end signal" to the communication partner. When each computer detects the transmitted "confirmation end signal", the tactile stimulus of DISP3 (FIG. 6)
It is output by the presentation units of the finger braille terminals 5 and 15 to present the conversation preparation completion vibration (S155). That is, DISP3
Is a signal notifying that the conversation for remote communication is ready and one of them can acquire the right to speak.
In this state, the keyboards 3 and 13 are prohibited from key input on either side, and no data is transmitted even if a key input is made. At the same time, the six-finger braille terminals 5 and 15 are key-locked so that they cannot be mechanically input.

In this state, the user who wants to speak first (in this embodiment, the user of the left block in FIG.
7 and below, the user presses the switch 29 of the six-finger braille terminal 5 or the space key of the keyboard 3. If the press of the switch 29 or the space key is detected, the process proceeds from S517 to S519, and the computer 1
Transmits a "speech start signal" to the listener (S51).
9) At the same time, key input prohibition or key lock is released (S521). Upon receiving the "speech start signal", the listener's computer 11 disables the keyboard 13 from key input and mechanically locks the braille input key section of the six-finger braille terminal 15 (S520, S522).

As described above, the speaker who has pressed the switch 29 or the space key first can acquire the right to speak and transmit character data for conversation, and the listener without the right to speak can input a key. I can't send it. The speaker who has obtained the right to speak has the Braille input key units 21 to 26 of the keyboard 3 or the six-finger braille terminal 5 unless an escape key or the like described below is pressed in S523.
Then, a conversation is input (S525 to S529). Here, the computer 1 outputs data to the voice modem 2 for each character, and transmits the data to the listener (S527).

The data for one character received by the listener is temporarily stored in a memory buffer and output to the presentation unit of the six-finger braille terminal 15 to inform the listener of the communication partner in real time (S524). To S532). The presentation on the listener's side is continued until a "speech end signal" described later is received.

When the speaker ends the conversation, the keyboard 3
Is pressed or the switch 27 of the six-finger braille terminal 5 is pressed. When the computer 1 detects that the escape key or the switch 27 has been pressed, the computer 1 performs steps S523 to S523.
Proceeding to 531, the key input of the speaker's keyboard 3 is prohibited, and the Braille input key section of the 6-finger braille terminal 5 is mechanically locked. Further, the computer 1 transmits a "speech end signal" to the listener, and returns to S517.

The listener receives this "speech end signal" and returns to S517, and waits for both speeches. Here, when the previous listener depresses the switch 29 of the six-finger braille terminal 15 or the space key of the keyboard 13, the right to speak is transferred, and the speaker and the listener are changed to establish a conversation.

The above protocol allows a user to have a conversation in real time, like a transceiver.

When the call is initially made and the other party is on a call with another party (busy), the DIS as shown in FIG.
The stimulus signal of P is presented to the transmitting side (speaker) until the call is disconnected, notifying that the calling party is busy.

In the meantime, while the conversation is being performed in the above-described method after S517, the listener's contact or re-listening, or a key input error on the speaker side or the cancellation of the conversation can be determined by using the following tactile stimulus. Can be communicated to the communication partner.

For example, the listener presses the switch 31 of the six-finger braille terminal 15 or the cursor movement key (←) of the keyboard 13 when the conversation is unknown. When the computer 11 detects the depression of the switch 31 or the cursor movement key, the computer 11 sends a "re-listening signal" to the speaker. The "re-listening signal" is indicated by DISP4 in FIG. Upon receiving the “re-listening signal”, the computer 1 of the speaker presents the tactile stimulus of the DISP 4 by the six-finger braille terminal 5. In addition, the listener's joint is transmitted using the tactile stimulus of DISP5 shown in FIG.

As a method of correcting a statement in a conversation of six-finger braille, the correction is transmitted by reciprocating a finger placed on the back of a partner's hand to the left and right. Therefore, the cancellation on the speaker side is transmitted using the tactile stimulus of DISP6 shown in FIG.

The above-mentioned DISP 6 applies a vibration of a constant frequency for 0.5 sec, a pause time to of 0 sec, 0.1 sec.
ec is driven with a time difference with a delay of six fingers, and presented to each finger in the order of Braille input key 23 → 22 → 21 → 24 → 25 → 26. Therefore, the stimulation site for each finger is stationary, but the stimulus of each finger is successively stimulated under the above-mentioned conditions, thereby causing a tactile apparent movement. Thus, 6
In the presentation unit of the finger braille terminal 5, by sequentially presenting the stimulus with an appropriate time difference in the above order, it is possible to give a feeling similar to a correction operation in the case of finger braille. Note that the above stimulus order may be reversed.

The embodiment of the remote communication with the communication device according to the present invention using the six-finger braille terminal has been described above. However, the start and the end of the conversation, the acquisition of the floor, the combination, the re-listening, The speech correction of the speaker may be presented on the six-finger braille terminal at a stimulation site other than the finger pad. In addition, the remote communication method represented by a six-finger braille terminal is appropriately presented by a character on a monitor device as another output device, a voice by a voice synthesizer, or a stimulus pin on a braille pin display. It is obvious that the present invention can be applied to a method of notifying the character data and the state of the conversation.

[0055]

As described above, the apparatus according to the present invention,
According to the method and the recording medium, remote communication between a person with communication impairment or a person with communication impairment and a healthy person can be performed in the same way as oral conversation while presenting the conversation state together with the conversation content. It is possible, and there is an effect that a barrier to information transmission due to a failure can be eliminated.
