Specification

Communication method between visual and visual equipment and character dolls and audio-visual device for executing this method

Technical field

The present invention relates to a communication method between an audiovisual device and a character doll when the audiovisual device executes a program that requires a response operation of the character doll,

The present invention also relates to an audio-visual apparatus comprising a combination of audio-visual equipment equipped with mutual communication means and character dolls.

Background technology

'' Currently, audio-visual equipment such as Television Radio is available.

It has been proposed that the character doll Puru combines a pet mouth bot. Therefore, of course, a communication method between both parties has also been proposed.

An object of the present invention is to provide a television, a radio, a projector, and other audiovisual devices, and various dramas and other blogs that require a response operation of character dolls based on communication with these audiovisual devices. In order to execute a program, a communication method between the above-mentioned visual equipment and the above-mentioned character dolls is established, and an audio-visual method capable of executing the communication method is established. By providing audio-visual equipment related to the combination of equipment and character dolls.

Disclosure of the invention

One of the aspects of the present invention is the mutual communication between audiovisual devices. When executing a program that requires the response action of character dolls based on the

The above communication is represented by an apparent communication in the form of a human-recognizable linguistic form, and a communication in the same sense as a signal concealed by a person's recognition. The communication method between the audiovisual equipment and the character dolls to be performed is as follows.

Another aspect of the present invention is to combine an audio-visual device with a character doll equipped with a voice generating device for expressing a linguistic form, and the audio-visual device described above is a method for displacing character dolls. Or, on both sides, incorporate an output device for concealed signals emitted by the recognition of the person who accompanies the apparent communication in the interlingual form, and the corresponding audiovisual device It is an audio-visual device equipped with a receiving and decoding device for a signal that is concealed by the above-mentioned person in a humanoid and a control unit for controlling predetermined units based on the decoding result.

The audio-visual equipment may be a television, radio, movie, tape recorder, or other audio-visual equipment.

In addition, as the character dolls, various dolls including those of animals, a pet robot, and the like can also be used.

The above-mentioned apparent communication is intended for the purpose of allowing the viewer to understand the contents, and in principle, uses expressions in a normal language format. This is audiovisual equipment and character dolls There is no substantial communication between each other. The above-mentioned sound generator performs the above-mentioned apparent communication by means for performing the above-mentioned communication, and radiates, for example, an appropriate sound synthesizing circuit, an amplifying circuit, and its output signal. Speaker and the like.

Examples of the carrier of the signal concealed by the recognition of the person include, for example, an ultrasonic wave or a radio wave of a non-audible frequency. In some cases, sound waves at audio frequencies can be used. When using sound waves with audible frequencies, it is preferable to use time-varying frequencies to conceal human perception, so that the sound can be heard in a specific signal. Make your audience aware.

Which carrier should be used should be determined in consideration of various conditions such as ease of configuration and strength against noise.

For example, the format of the signal hidden by the recognition of the person can be configured as a digital code corresponding to each expression of a required number of language formats. In this case, if a 4-bit digital code is constructed, it can be associated with expressions in 16 different language formats without language, so this is sufficient for simple dialogue. You. The digital co one de, the other a Eba, 2 0 0 0 0 H _z signal 2 representing a 1 in Sai cycle of搆in FSK modulation to represent 0 at the signal 4 Sai cycle of 4 0 0 0 0 H z Can be achieved. If ultrasound is used as the carrier, the viewer of audio-visual equipment and character dolls will be able to hear it. So, it fits the purpose. Note that it is necessary to output one digital code signal with the start bit and the stop bit sandwiched between the start bit and the stop bit. If an audible sound wave whose frequency changes with the above-mentioned time is used as a carrier, a digital code signal is formed by intermittently changing the carrier, for example, in a different manner. .

Further, as a device for outputting a signal concealed by the above-mentioned person, a device capable of outputting any one of the above signals may be used. Specifically, the ultrasonic wave is used as the carrier, and the above! ^{1 If} SK modulation is adopted, for example, a filter circuit inserted into the audio circuit to separate non-audible frequency components contained in the audio signal, and a separated 'inaudible frequency component' It can be configured with an appropriate trans- mitter that emits light. The above-mentioned audio signal is received by a broadcast accompanied by such components, or read out from a storage depth recorded with such components, and input to an output device of the same. Sound signal. In addition, the above-mentioned trans-juicer can be usually arranged for one or both of the audio-visual equipment and the character dolls, and can be configured for both transmission and reception. An appropriate piezoelectric vibrator can be employed as the transducer.

It goes without saying that the above-mentioned reception decoding device should be determined according to the type and type of the signal hidden from human recognition. Specifically, if the carrier is an ultrasonic signal and the signal is FSK modulated, for example, a transducer that picks up the ultrasonic signal, an amplifier, and a decoder. And Further, in the character doll, for example, based on the decoding result of the reception decoding device, the control unit may include several types of language expressions held by the speech synthesis circuit. The voice data can be configured as a selection circuit that selects the required language expression.

By the way, in order to realize the present invention, it is natural that drama and other data must be supplied to the audiovisual device. For this purpose, a storage device storing these data is provided in the same way as described above, and the data is read out from the storage device. Need to be done.

The data above this case must be provided with the following conditions. .

First, the memory devices set in the audiovisual equipment and character dolls have a one-to-one relationship between the audio signal data of each expression in linguistic form and each code signal concealed by human recognition. It must be recorded in association with. Or it must be broadcast in association. That is, the hidden signal and the linguistic expression in the apparent communication must be simultaneously radiated to the above-mentioned person. .

Therefore, in the above description, when ultrasound is adopted as a carrier of a signal concealed by human recognition (hereinafter, narrowed down in this case), and in the case of parenthesized broadcasting, description will be omitted. For example, at the same time, in the storage device, at the same position of the audio recording unit, the audio signal of each language format is associated with the same meaning. The digital code signal of the ultrasonic wave expressing the above is also recorded.

Since the present invention has the above-described configuration, it is used in the following manner.

First, a mutually corresponding storage device for recording data such as drama is set in the audiovisual device and the character doll.

When the audiovisual device and the character doll are operated at the same time, the audiovisual device develops dramas or the like based on the given memory depth.

In an appropriate scene in the development of a dramatic drama, etc., the audio-visual equipment Pururu conducts an apparent dialogue in the form of linguistic form between the characters appearing and the character dolls. At the same time, a communication having the same effect is performed between the persons according to the hidden signal which cannot be recognized by a person. As described above, for example, mutual actual communication is performed according to the ultrasonic digital code signal. That is, when one of the transducers emits an ultrasonic digital code signal together with the apparent communication of the speaker, on the other hand, the digital A code signal is received by a similar transducer, decoded and responds to the corresponding apparent verbal and non-verbal response, accompanied by a response to the required ultrasonic digital code signal Stuff.

In this way, the communication between the audiovisual equipment and the character dolls is apparently expressed in a linguistic form, and the Can give a very rich taste.

According to the present invention, the communication between the audiovisual device and the character dolls can be performed in an apparently linguistic form, so that the viewer can understand the essence of the communication. On the other hand, since the actual communication is performed using a signal that is concealed, it does not reach the viewer's recognition and malfunctions due to the viewer's conversation and other noises. Can be lost.

FIG. 4 is a block diagram of a circuit built in the robot, FIG. 4 is an explanatory diagram schematically showing a waveform of a digital code signal, and FIG. 5 is an explanatory diagram schematically showing a waveform of an audio signal.

BEST MODE FOR CARRYING OUT THE INVENTION In order to explain the present invention in more detail, an embodiment will be described below based on the accompanying drawings.

Ultrasound is used as a carrier for signals hidden by human perception.

As a signal format, a digital code is used, and different codes are given in accordance with the required number of types of expressions in each language format. In this example, a 4-bit digital code was employed because only a few simple conversations were allowed. Needless to say, this can be used for 16 linguistic expressions. In addition, this digital code is represented by a schematic diagram of FIG. 1 is represented by 2 cycles of the signal, and 0 is represented by 4 cycles of the signal of 40000 Hz. Note that one code is output with the start bit and the stop bit sandwiched between the start bit and the stop bit. Next, audio-visual equipment and character dolls that implement this method, and storage devices that provide drama and other data to them will be described.

In this example, as shown in FIG. 1, a television 2 equipped with a VTR 1 is used as an audiovisual device, and a pet robot 3 is used as a character doll. Magnetic recording tapes and IC cassettes will be used as storage devices for recording dramas and other data.

The magnetic recording tape is usually called a video tape. The audio track of this magnetic recording tape records the above-mentioned digital code signal in addition to a normal audio signal. The digital code signal is recorded in the same position as the audio signal of the required language format recorded in the audio track. This digital code signal is recorded several times in a row to ensure recognition. The IC cassette also corresponds to the magnetic recording tape and records the digital code signal and the expression data in a language format to be responded to when the digital code signal is recognized. Puru.

Therefore, in this example, since the contents of the magnetic recording tape and the IC cassette are the same as those described above, only the television 2 speaks, and the pet robot 3 responds only. Teru.

The television 2 has an ultrasonic signal processing circuit shown in FIG. 2 in addition to a normal circuit.

This ultrasonic signal processing circuit is connected to an audio detection circuit 4 in the television 2 so as to separate the output into a high-frequency component and a low-frequency component, and outputs the HPF 5 and the LPF 6 and the output of the HPF 5. It is composed of an amplifier 7 for amplifying the power and a piezoelectric vibrator 8 for emitting the output of the amplifier 7.

The amplifier 9 drives the speaker 10 by amplifying the output of the LPF 6. This is done with existing circuits.

—The Robot 3 is equipped with the circuit shown in FIG. This circuit includes a similar piezoelectric vibrator 11 that picks up the ultrasonic signal radiated from the piezoelectric vibration module, a BPF 12 that passes only the ultrasonic sound signal, and an amplifier 13 that amplifies the output signal. A decoder 14 for decoding the output signal of the amplifier 13 and selecting an output language audio signal of the subsequent speech synthesis circuit 15; the speech synthesis circuit 15; an amplifier 16 for amplifying the output; and an amplifier. It consists of 16 speakers 17 that emit outgoing audio signals.

The speech synthesizer that holds the speech data in the speech synthesis circuit 15 forms a replaceable IC cassette as described above.

So this is used in the next step.

First, the magnetic recording tape is set on the VTR 1 provided in the television 2. The IC cassette that recorded the magnetic recording tape and the corresponding data was also provided to the pet sigma bot 3 set.

Assuming that the television 2, the VTR 1 and the pet robot 3 are switches, the television 2 develops dramas and the like based on the set magnetic recording tape.

In the course of the development of the above-mentioned dramas, etc., calls were made to the pet π-bot 3 in the form of a language in accordance with the human beings in the video of the television 2 and at the same time, the ultrasonic digital code signal Is radiated from the piezoelectric vibrator 8. The output of the audio detection circuit 4 of the television 3 is a high-frequency component, that is, an ultrasonic digital code signal component schematically shown in FIG. 4, and a schematic diagram of FIG. The audio signal is divided into audio signal components. Normally, only the audio signal component is amplified by the amplifier 9 and radiated from the speaker 10, but in a predetermined scene, the audio signal component is predetermined. The digital code signal component corresponding to (predetermined language expression) passes through the HPF 5, is amplified by the amplifier 7, and is radiated from the piezoelectric vibrator 8.

Then, the pet robot 3 receives the digital code signal with the piezoelectric vibrator 11, decodes the digital code signal with the amplifier 13, decodes it with the decoder 14, and sends the selection signal to the speech synthesis circuit 15 in the subsequent stage. And outputs a speech signal of the corresponding response language format expression. In this way, the corresponding response can be made in the language format.

This can be performed as if the pet robot 3 responds directly to the call in the language format of the person in the video of the television 2. Then TV 2 Communication between the characters (animals, etc.) in the video and the pet robot 3 is realized in the form of an apparent linguistic expression, and can give the viewer a very rich taste.
