Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method of communication between an audiovisual device and a character doll when the audiovisual device executes a program that requires response actions of the character doll.

[Prior Art] At present, no combination of audiovisual equipment such as televisions, radios, etc. with character dolls or pet robots has been proposed, and therefore, naturally, no method of communication between the two has been proposed either. .

[Problems to be Solved by the Invention] The problem to be solved by the present invention is to solve problems in TVs, radios, projectors, and other audiovisual equipment, and various dramas and other programs that require response movements of character puppets to communicate with these equipment. In order to carry out this, it is necessary to establish a communication method between the above audiovisual equipment and character puppets.

[Means for Solving the Problems] The gist of the configuration of the present invention is that when executing a program that requires response actions of character dolls based on mutual communication with audiovisual equipment, Audio-visual equipment and character dolls that carry out communication through apparent communication using verbal expressions that are recognizable to humans, and communication using communication means that are hidden from human recognition. It is a method of communication.

The above-mentioned audiovisual equipment may be a television set, radio, movie projector, tape recorder, or any other audiovisual equipment.

Furthermore, the character dolls can be of various types, including various dolls including animal dolls, so-called pet robots, and the like.

The purpose of the apparent communication mentioned above is to make the viewer understand the content.1 It is sufficient that normal language expressions are used normally, and there are no restrictions on this. Then, there is no meaning in Comic Unicage.

Examples of the transmission means hidden from human recognition include ultrasonic waves and radio waves with inaudible frequencies. When deciding what kind of means to adopt, various conditions such as ease of construction and resistance to noise should be taken into consideration.

, The representation of the communication content can be configured, for example, by a digital code corresponding to each of the required number of linguistic representations. In this case, if a 4-bit digital code is constructed, it goes without saying that it can correspond to 16 different language expressions, so this is sufficient for use in simple dialogue. This digital code is, for example, 20000H
It is possible to express 1 in 2 cycles of the z signal, and to express 0 in 4 cycles of the 40000H2 signal.

When employing ultrasonic waves as the transmission means, if such a modulation method is adopted, viewers of audiovisual equipment and character dolls will not be able to hear the ultrasound, so this is consistent with the purpose. Note that it is necessary to output each digital code signal with a start bit and a stop bit sandwiched at the front and rear.

In order to realize this method, the following configurations are required for audiovisual equipment, character dolls, and storage devices for providing dramas and other data to them.

First, storage devices such as magnetic recording tapes and magnetic disks that record data such as dramas set in audiovisual equipment and character dolls contain audio signals of verbal expression and signals of communication means hidden from human recognition. This is because the means of communication that is hidden from human recognition and the verbal expression that is the apparent means of communication must be recorded in association with each other, as described above, and must be radiated simultaneously.

Therefore, as mentioned above, if the above-mentioned ultrasonic waves are used as a transmission means hidden from human recognition (the following explanation will focus on this case), in the storage device,
At the same position in the audio recording section, the ultrasonic digital code signal expressing the same meaning is also recorded in correspondence with the audio signal of each language expression.

Further, in this case, the audiovisual equipment and character dolls require an output device for the ultrasonic digital code signal. This includes, for example, a filter circuit inserted into the audio circuit in order to separate the ultrasonic digital code audio signal contained in the audio signal read from the storage device and input to the audiovisual equipment or the character doll, and and a suitable transducer that emits an ultrasonic digital code signal component.

On the other hand, audible frequency components such as language expressions are processed by an existing audio signal circuit and emitted from a speaker.

This circuit must be specially provided for character dolls. The voice signal circuit for linguistic expression built into the character doll can be composed of, for example, a suitable voice synthesis circuit, an amplification circuit, and a speaker for emitting the output signal thereof.

Thus, the linguistic expression signal and the corresponding digital code signal, which have been recorded in a mixed state in the storage device, are simultaneously emitted through the respective speakers or transducers.

Furthermore, the audiovisual equipment and character dolls must be equipped with a receiving and decoding circuit for the ultrasonic digital code signal. This circuit can be composed of, for example, a transducer that picks up an ultrasonic digital code signal, an amplifier, a decoding station, and a control section that controls each section based on the decoding results. In the above-mentioned audio-visual equipment, the control section can be configured as a circuit that selects a specific one from the options for proceeding with a drama or the like based on the decoding result. Further, in the above-mentioned character dolls, the control section can be configured as a circuit for selecting an appropriate language expression from the above-mentioned speech synthesis circuit.

Note that the transducer can be arranged individually in both audiovisual equipment and character dolls, and can be configured to serve both for transmission and reception. A suitable piezoelectric vibrator can be used as the transducer.

[Operation] Since the present invention is constructed as described above, it is carried out as follows.

First, a mutually compatible storage device such as a magnetic tape or a magnetic disk is set in the audio-visual equipment and the character doll to record data such as a drama as described above.

When the audio-visual equipment and the character puppets are operated simultaneously in this way, the audio-visual equipment develops a drama or the like based on the given storage device.

On the other hand, in appropriate scenes in the development of dramas, etc., an apparent dialogue using verbal expressions takes place between audiovisual equipment or its characters and character puppets, and at the same time, concealment that cannot be recognized by humans is carried out. Communication with the same purpose is carried out between the parties using the communication means provided. As mentioned above, mutual actual communication is carried out using, for example, ultrasonic digital code signals.

That is, when an ultrasonic digital code signal is emitted from one transducer along with apparent communication from a speaker, the other side receives this digital code signal with a similar transducer, decodes it, and produces a corresponding apparent signal. verbal and non-verbal responses, and are accompanied by responses using the necessary ultrasonic digital code signals.

In this way, the audiovisual equipment and the character puppets communicate with each other through seemingly verbal expressions, which can provide viewers with a very deep interest.

[Example] An embodiment of the present invention will be described below based on the drawings.

This embodiment is an example in which ultrasonic waves are used as a transmission means hidden from one person's recognition.

Digital codes will be used to express the content of the communication, and separate codes will be given to correspond to the required number of language expressions. In this embodiment, a 4-bit digital code is used because only a few types of simple dialogues are required. Needless to say, this makes it possible to correspond to 16 different linguistic expressions.

Further, as shown schematically in FIG. 1(a), this digital code is designed such that 1 is expressed in 2 cycles of a 20,000 Hz signal, and 0 is expressed in 4 cycles of a 40,000 H2 signal. By adopting this method of modulating ultrasonic waves,
Since viewers of audiovisual equipment and character dolls cannot hear this, this conforms to the purpose. Note that each code signal is output with a start bit and a stop bit sandwiched at the front and rear.

Next, audio-visual equipment, character dolls, and recording devices for supplying drama and other data to these devices will be described. .

In this example, a television set equipped with a VTR is used as the audiovisual equipment, and a pet robot is used as the character doll. Magnetic recording tapes and IC cassettes are used as storage devices for recording dramas and other data.

The above magnetic recording tape is commonly called a videotape. In addition to the normal audio signal, the above-mentioned digital code signal is recorded on the audio track of this magnetic recording tape.
It is recorded at the same position in correspondence with the audio signal of the desired language format recorded on the audio track. Several digital code signals are recorded in succession to ensure recognition. The above IC cassette also corresponds to the above magnetic recording tape,
The digital code signal and the linguistic expression data to be responded to when the digital code signal is recognized are recorded in association with each other. Therefore, in this example, since the contents of the magnetic recording tape and IC cassette are as described above, only the TV set side speaks to the user, and the pet robot side only responds.

The above-mentioned television is equipped with an ultrasonic signal processing circuit as shown in FIG. 2 in addition to normal circuits.

This ultrasonic signal processing circuit consists of HPF2 and LPF3, which are connected to the audio detection circuit l in the television set in order to separate the output into high frequency components and low frequency components;
2, and a piezoelectric vibrator 5 that radiates the output of the amplifier 4.

The amplifier 6 amplifies the output of the LPF 3 and drives the speaker 7. This is an existing circuit. On the other hand, a pet robot is equipped with a circuit as shown in Figure 3.

This circuit includes a similar piezoelectric vibrator 8 that picks up the ultrasonic signal emitted from the piezoelectric vibrator 5, a BrF3 that passes only the ultrasonic audio signal, an amplifier lO that amplifies its output signal, and an amplifier lO a decoder 11 that decodes the output signal of and selects the output language audio signal of the speech synthesis circuit 12 in the subsequent stage; the speech synthesis circuit 12; an amplifier 13 that amplifies the output thereof; This configuration includes a speaker 14 that performs the following functions.

In the above-mentioned speech synthesis circuit lz, the speech synthesizer that holds the speech data is configured as a replaceable IC cassette, as described above.

Since this embodiment is configured as described above, it is used in the following manner.b.

First, the m non-recording tape is set in the VTR installed in the television. The magnetic recording tape and the IC cassette containing the corresponding data are also set in the pet robot.

When the television, VTR, and pet robot are turned on in this way, the TV screen begins to play dramas based on the magnetic recording tape set.

During the development of the above-mentioned drama, etc., a person or the like in a television image calls out to the pet robot using verbal expressions, and at the same time, an ultrasonic digital code signal is emitted from the piezoelectric vibrator 5. The output of the television audio detection circuit l is a high frequency component, that is, the
The ultrasonic digital code signal component is separated into an ultrasonic digital code signal component as schematically shown in FIG.
However, in a predetermined scene, a digital code signal component corresponding to a predetermined audio signal component (predetermined language expression) passes through the HPF 2, is amplified by the amplifier 4, and is emitted from a piezoelectric vibration. It is emitted from child 5.

Then, the pet robot receives the digital code signal with the piezoelectric vibrator 8, amplifies it with the amplifier 10, decodes it with the decoder 11, exerts a selection effect on the subsequent speech synthesis circuit 12, and generates the corresponding response language. This is to output an audio signal of expression. A corresponding response is thus given by the speaker 14 in verbal form.

This is done as if the pet/toy robot were to respond directly to a verbal call from a person on television. As a result, communication was established between the television (or the people, animals, etc. in the video) and the pet robot through apparent verbal expressions.
It can give viewers a lot of interest.

Furthermore, in actual communication, ultrasonic signals of inaudible frequencies are used, and the signal format described above is adopted, so that malfunctions caused by audience conversations and other noises can be extremely reduced.

[Effects of the Invention] According to the present invention, communication between audiovisual equipment and character puppets is performed in the form of apparent verbal expression, allowing the viewer to understand the exchange, while making it possible for the viewer to understand the exchange, while making it difficult to communicate in real life. Since the communication is carried out using a hidden transmission means, the viewer is not aware of this and there is no possibility of malfunctions caused by the viewer's conversation or other noises.
