Description

Technical Field

[0001] The present invention relates to the field of communication technology, and more particularly to a silent communication system for acquiring information in a non-visual and non-auditory manner. Background Art

[0002] Due to the structure of the human body, information receivers often acquire external information through vision and hearing. For example, a receiver in a monitoring room might view warehouse inventory via video, acquiring information visually and auditorily, regardless of distance. In some scenarios where vision and hearing are unavailable, receivers typically acquire information through contact, or through a combination of touch and vision or hearing. For example, people with sudden deafness or blindness cannot normally acquire external information and can only interact with the outside world through gestures or sound cues. Another example is understanding an object's size by touching it, or sensing temperature changes through skin contact. However, this method of acquiring information is easily limited by distance and can result in low accuracy.

[0003] In the prior art, patent application 202110905386.0 provides an "information transmission method, device, equipment, medium and program product". The specific scheme is: by responding to a calibration instruction, driving multiple contact units on one or more contact arrays set on the wearable device to move in a preset manner, thereby adjusting the wearing position or posture of the wearable device and making the wearable device reach a preset usage state; then, based on the acquired information to be transmitted, at least one three-dimensional figure is determined, and the three-dimensional figure is used to represent the information to be transmitted; then, the contact array is controlled to transmit the three-dimensional figure to the user's skin so that the user perceives the information to be transmitted through the skin. This technical solution achieves the following technical effects: the three-dimensional figure is transmitted to the user's skin in the form of pressure through the contact array, replacing visual information transmission with tactile sensation, solving the technical problem of how to increase the way to perceive information; and achieving the technical effect of being able to use tactile sensation to obtain information when it is inconvenient for the eyes to obtain information or it will cause distraction and lead to safety accidents. However, in this patent application, the device perceives information through skin touch, and the device structure is complex and requires calibration before use, and it cannot transmit information efficiently and sensitively.

[0004] Patent application 201611227153.5 provides "an information transmission method and apparatus, and a wearable device." The specific solution is: detecting whether the user wearing the first wearable device performs a handshake action; if a handshake action is detected, controlling the bone conduction module in the first wearable device to convert the first audio signal used to describe the first interactive information preset by the first wearable device into a first vibration signal and transmit it through the bone medium, so that the second wearable device worn by the user's handshake partner converts the first vibration signal into the first audio signal through a solid microphone and identifies the first interactive information from the first audio signal. This technical solution transmits information through vibration, which requires contact between the two parties to complete the information transmission and is not suitable for long-distance communication.

[0005] In summary, in current common communication methods, information receivers mostly obtain information through visual and auditory means. However, in certain environments where silent work is required, receiving information through traditional visual and auditory means can significantly impact ongoing work or tasks. For example, if an emergency situation information is sent to a live television host, if the host receives the information directly in the form of images, text, audio, or video, the live broadcast will be disrupted. Similarly, if instructions are sent to civil servants performing public security or counter-terrorism investigations in the form of traditional images, text, audio, or video, the task may fail. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above-mentioned defects of the prior art and provide a silent communication system for obtaining information without visual or auditory means.

[0007] According to a first aspect of the present invention, a silent communication system for acquiring information without visual or auditory perception is provided. The system comprises an information receiving module and an information sending module, wherein:

[0008] The information receiving module is used to analyze the received information and extract signal features, generate an electrical stimulation signal corresponding to the signal features; apply the electrical stimulation signal to the stimulation area of the information receiver in a non-invasive electrical stimulation manner, so as to induce the information receiver's brain to have a natural intuitive feeling for the corresponding non-stimulated area, thereby allowing the information receiver to obtain the information content based on the natural intuitive feeling;

[0009] The information sending module is used to encode and send information in the form of actions, pictures, text, audio and video.

[0010] According to a second aspect of the present invention, there is provided an information receiving device, comprising the information receiving module in the above system, the information receiving device comprising an information receiving unit, an electrical stimulation unit and an electrode unit, wherein the electrical stimulation unit is connected to the electrode unit, wherein:

[0011] The information receiving unit is used to receive and analyze the information from the sending end, extract the signal characteristics, and transmit it to the electrical stimulation unit;

[0012] The electrical stimulation unit is used to output a corresponding electrical stimulation signal according to the characteristics of the received signal;

[0013] The electrode unit is used to apply the electrical stimulation signal to the stimulation part of the information receiver in a non-invasive electrical stimulation manner, so as to induce the natural intuitive feeling of the information receiver's brain to the corresponding non-stimulation part, and then allow the information receiver to obtain information content based on the natural intuitive feeling.

[0014] Compared with the existing technology, the advantage of the present invention is that it provides a silent communication system for obtaining information without visual or auditory means, so that the information receiver does not obtain information in the form of pictures, text, audio and video, etc., and the information sender can send information content in the form of actions, pictures, text, audio and video, etc., and no sound or light signals are emitted during the information acquisition process, and it is not restricted by spatial distance. It has better silent effect and confidentiality, so that the information receiver and the information sender can receive and send information more accurately in scenarios where visual and auditory functions cannot be used.

[0015] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0021] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0022] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0023] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0024] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0025] See also Figure 1 As shown, the silent communication system for obtaining information in a non-visual and non-auditory manner includes an information receiving module, an information sending module and an information transmission module.

[0026] The information receiving module includes an information decoding unit and a natural intuition induction unit; wherein the information decoding unit is used to parse the received information and generate a corresponding electrical stimulation signal; the natural intuition induction unit is used to apply the electrical stimulation signal to the information receiver's arms, wrists, ankles, calves and other stimulation parts in a non-invasive electrical stimulation manner, so as to induce the information receiver's brain to feel natural intuition such as touch, pressure, vibration, patting, and tingling of non-stimulation parts such as fingers, palms, toes, and toes, so that the information receiver obtains the information content through natural intuition. It should be noted that the natural intuition feeling containing the information content includes one natural intuition feeling or a combination of multiple natural intuition feelings, and has a corresponding relationship with the information content.

[0027] The information transmission module includes an information recognition unit and an information encoding unit, which are used to identify and encode information content in the form of actions, text, images, audio and video. When sending information in the form of actions, the communication system collects the brain and myoelectric signals of the information sender during the action, then encodes the information content to be expressed by the brain and myoelectric signals into a transmission signal, and then sends the transmission signal to the information transmission module. In addition, the communication system can also collect EEG signals caused by the information sender's conscious brain activity when he is not moving, encode the information content to be conveyed by the conscious activity into a transmission signal, and then send the transmission signal to the information transmission module.

[0028] The information transmission module is used to transmit the signal encoded in the previous information sending module to the information receiving module through data cables, cellular mobile communications, Wi-Fi, etc.

[0029] Combine Figure 1 As shown, when a message recipient replies to a message received via the message receiving module, the recipient's system role changes to that of a message sender. The message sending module then sends the reply content in the form of actions, text, images, audio, or video, which is then transmitted to other message recipients via the message transmission module. The process for other message recipients to receive and reply to messages is the same as above and will not be repeated here.

[0030] See also Figure 2 As shown, the workflow of the information receiving module in the silent communication system for obtaining information without visual or auditory senses includes the following steps.

[0031] Step S110: generating an electrical stimulation signal according to the received information.

[0032] First, the received information is parsed, and the signal features are extracted to generate the corresponding electrical stimulation signal.

[0033] For example, the received information is filtered to extract time domain features, and after being transformed into the frequency domain through Fourier or wavelet transform, the frequency domain features are extracted; the combined features of the time and frequency domains are used as signal features, and the signal features are compared with the preset information features to obtain the information content; then, an electrical stimulation signal is generated based on the correspondence between the preset information content and the electrical stimulation signal self-test.

[0034] Step S120 , applying an electrical stimulation signal to a corresponding body part of the information receiver in a non-invasive manner.

[0035] For example, electrical stimulation signals are applied to the recipient's arms, wrists, ankles, calves, etc. via electrodes. The electrodes can be patch-type electrodes or packaged in wearable devices to facilitate non-invasive application to the body.

[0036] Step S130, inducing the information receiver's brain to have a natural and intuitive feeling about the corresponding non-stimulated part.

[0037] Since the electrical stimulation signal acts on the nerve bundles and nerve endings in the arms, wrists, ankles, calves and other parts in a non-invasive electrical stimulation manner, it will induce the information receiver's brain to have natural and intuitive feelings such as touch, pressure, vibration, slapping, and tingling in non-stimulated parts such as fingers, palms, toes, and feet.

[0038] In this communication method, inducing natural and intuitive feelings such as vibration, touch pressure, and tingling in the fingers, palms, toes, and other parts of the information receiver can be achieved by adjusting the waveform, amplitude, width, interval and other parameters of the electrical stimulation signal acting on the stimulation parts such as the arm, wrist, ankle, and calf. Therefore, the communication method of the present invention needs to parse the information and adjust the waveform, amplitude, width, interval and other parameters of the electrical stimulation signal according to the feature values extracted after parsing, so as to obtain an electrical stimulation signal containing information content.

[0039] Step S140: The information receiver obtains the information content based on natural intuition.

[0040] The information receiver obtains the information content corresponding to the natural intuitive feeling based on the natural intuitive feeling. The information receiver can obtain the information content through one natural intuition or a combination of multiple natural intuitions, where the natural intuitive feeling includes but is not limited to natural intuitive feelings such as touch, vibration, slapping, and tingling. For example, when expressed as one natural intuition, the natural intuitive feeling of finger tingling for a certain duration represents a stop command. When expressed as a combination of multiple natural intuitions, the natural intuitive feeling of palm touch represents the dot symbol in Morse code, and the natural intuitive feeling of palm vibration represents the dash symbol in Morse code. Through this design, the information receiver obtains a combination of natural direct feelings of touch and vibration in a manner similar to receiving Morse code, and obtains the information content through combined decoding.

[0041] In summary, the present invention proposes a silent communication system for obtaining information in a non-visual and non-auditory manner, which converts information content into electrical stimulation signals and acts on the arms, wrists, ankles, calves and other parts of the information receiver, thereby stimulating the corresponding nerve bundles and nerve endings, and inducing the information receiver's brain to have a natural and intuitive feeling for non-stimulated parts such as fingers, palms, toes and toes, so that the information receiver does not obtain information in the form of pictures, text, audio and video, etc., and at the same time enables the information sender to send information content in the form of actions, pictures, text, audio and video, etc., and does not emit sound and light signals during the information acquisition process, is not restricted by spatial distance, and has a good silent effect and confidentiality. During the information transmission process, even if the information receiver and the information sender are not in the same physical space, it will not affect the transmission of information.

[0042] Accordingly, the present invention also provides an information receiving device for realizing silent communication of information acquisition without visual or auditory senses. The information receiving device includes the above-mentioned information receiving module and can be worn on the wrist, hand, foot or other body parts of the information receiver in a wearable manner. Figure 3 As shown in FIG, the device includes an information receiving unit, an electrical stimulation unit, a power supply unit, and an electrode unit. Each unit can be implemented using dedicated hardware, a processor, or an FPGA.

[0043] The information receiving unit is composed of but not limited to a signal processing subunit, a first wireless transmission subunit, etc. The signal processing subunit is connected to the first wireless transmission subunit, and is used to perform signal analysis after filtering, digital-to-analog conversion, and other processing on the received signal containing information content, and extract the characteristics corresponding to the signal. The information receiving unit can communicate with other units in a wired or wireless manner. If the information receiving unit receives a signal containing information content in a wireless transmission manner, the first wireless transmission subunit outputs the signal to the signal processing submodule, and sends the characteristic signal generated by the signal processing submodule to the electrical stimulation unit through the first wireless transmission subunit. If the information receiving unit receives a signal containing information content in a wired transmission manner, the first wireless transmission subunit sends the signal characteristics generated by the signal processing subunit to the electrical stimulation unit in a wired transmission manner.

[0044] The electrical stimulation unit includes but is not limited to a wireless transmission second subunit, a signal generator subunit, a power amplifier subunit, etc. The wireless transmission second unit is used to receive the signal characteristics from the information receiving unit and transmit them to the signal generator subunit. The signal generator subunit is used to generate an electrical stimulation characteristic signal corresponding to the signal characteristics, and then transmit it to the power amplifier subunit. The power amplifier subunit generates a corresponding electrical stimulation signal based on the electrical stimulation characteristic signal, and then transmits it to the electrode unit. It should be understood that if the electrical stimulation unit and the information receiving unit are integrated into the same hardware, or the electrical stimulation unit and the information receiving unit are both independent hardware modules, and the data between the two hardware is transmitted through a data wire, there is no need for data interaction via the wireless transmission second subunit.

[0045] The power supply unit is used to provide power to the information receiving unit and the electrical stimulation unit. The power supply unit is connected to the signal processing subunit and the first wireless transmission subunit in the signal receiving unit, and the second wireless transmission subunit, signal generator subunit, and power amplifier subunit in the electrical stimulation unit.

[0046] The electrode unit is connected to the electrical stimulation unit and is used to apply the electrical stimulation signal output by the electrical stimulation unit to the arms, wrists, ankles, calves and other parts of the information receiver in a non-invasive electrical stimulation manner, stimulating the corresponding nerve bundles and nerve endings, and inducing the information receiver's brain to feel natural and intuitive sensations such as touch, pressure, vibration, slapping, and tingling in non-stimulated parts such as fingers, palms, toes, and toes. The electrode unit includes but is not limited to being composed of one or more electrodes such as gel electrodes, metal dry electrodes, flexible electrodes, microneedle electrodes, and fabric electrodes. During use, the electrodes act on the stimulation site in the form of a single structure or an array.

[0047] The communication process of the present invention is described below by taking the example of transmitting information to a TV host.

[0048] Specifically, the sender of the information uses hand gestures to send emergency information to a live TV host. The information receiver, then worn on the host's wrist, uses non-invasive electrical stimulation to induce the host's brain's natural perception of touch, pressure, and vibration in the palm of their hand, allowing the host to receive the transmitted information from this natural, intuitive perception. The information receiver, worn on the host's wrist, includes an information receiving unit, an electrical stimulation unit, and an electrode unit. The two units are integrated into the same hardware, and the electrode unit is a microneedle array electrode.

[0049] The sender uses different gestures to send breaking news to the TV host. A clenched fist signaled "start broadcasting"; an extended palm signaled "stop broadcasting"; a flexed wrist signaled "speed up, prepare to insert new content"; and an inward rotation signaled "slow down, the following content will be cut."

[0050] When the information receiving unit receives a signal containing information content, it first filters the signal to remove interference from clutter signals and obtains time domain data D t , and after Fourier transform, the frequency domain data D is obtained f Then, extract the signal feature F(D t ,D f ) and compare it with the preset information features to obtain the information content. Next, the electrical stimulation parameters P(M,A) are determined based on the information content. s ,W,f s ,T s ), including waveform M, amplitude As, width W, frequency f s , interval T sFinally, the electrical stimulation signal S(M,A) is generated according to the electrical stimulation parameters. s ,W,f s ,T s ) and applied it to the TV host's wrist through a microneedle array electrode.

[0051] Specifically, when the signal feature is F0(D t0 ,D f0 ), the information content is "start broadcasting", then the electrical stimulation parameters are P(M0,A s0 ,W0,f s0 ,T s0 ); When the signal characteristic is F1(D t1 ,D f1 ), the information content is "stop broadcasting", then the electrical stimulation parameter is P(M1,A s1 ,W1,f s1 ,T s1 ); When the signal characteristic is F2(D t2 ,D f2 ), the information content is "Speed up the speech, prepare to insert new broadcast content", then the electrical stimulation parameter is P(M2,A s2 ,W2,f s2 ,T s2 ); When the signal characteristic is F3(D t3 ,D f3 ), the information content is "reduce the speaking speed, the following broadcast content will be cut", then the electrical stimulation parameter is P(M3,A s3 ,W3,f s3 ,T s3 ).

[0052] Therefore, when the device worn by the TV host receives the "start broadcast" message, the electrical stimulation unit will stimulate the TV host according to the electrical stimulation parameters P(M0, A s0 ,W0,f s0 ,T s0 ) generates an electrical stimulation signal S(M0,A s0 ,W0,f s0 ,T s0 ), and acted on the wrist of the TV host through the microneedle array electrode, inducing the TV host's brain to feel the natural and intuitive vibration of the palm twice (the interval between the two inductions was 3 seconds); when the device worn on the TV host's wrist received the "stop broadcast" message, the electrical stimulation unit activated the electrical stimulation parameters P(M1,A s1 ,W1,f s1 ,T s1 ) generates an electrical stimulation signal S(M1,A s1 ,W1,f s1 ,T s1), and acted on the wrist of the TV host through the microneedle array electrode, twice inducing the TV host's brain to feel the natural and intuitive touch and pressure of the palm (the interval between the two inductions was 3 seconds); when the device worn on the TV host's wrist received the message "Speed up and prepare to insert new broadcast content", the electrical stimulation unit activated the electrical stimulation parameters P(M2,A s2 ,W2,f s2 ,T s2 ) generates an electrical stimulation signal S(M2,A s2 ,W2,f s2 ,T s2 ), and act on the wrist of the TV host through the microneedle array electrode, inducing the TV host's brain to feel the vibration and touch of the palm of the hand (the interval between the two inductions is 3 seconds); when the device worn on the TV host's wrist receives the message "slow down the speech speed, the following broadcast content will be deleted", the electrical stimulation unit will generate a signal according to the electrical stimulation parameters P(M3,A s3 ,W3,f s3 ,T s3 ) generates an electrical stimulation signal S(M3,A s3 ,W3,f s3 ,T s3 ) and acted on the TV host's wrist through microneedle array electrodes, inducing the TV host's brain to feel the touch and vibration of the palm of his hand naturally (the interval between the two inductions was 3 seconds).

[0053] In summary, the above communication process adopts a silent communication method that obtains information without visual or auditory senses. After the information sender sends the emergency information to the TV host through gestures, the TV host obtains the emergency information based on the natural intuitive feeling of the non-stimulated parts, avoiding the interference of pictures, text or audio and video in the traditional communication method on the live broadcast.

[0054] In summary, in common communication methods, information recipients typically obtain information through sight and hearing. In scenarios where traditional methods are unavailable, or where silent operation is required, obtaining external information through traditional sight and hearing methods can significantly impact ongoing work or tasks. In scenarios where both sight and hearing are unavailable, or where only sight or hearing are available, information recipients typically obtain information through contact, or through a combination of touch and sight or hearing. These communication methods rely on the human body's visual and auditory functions, making it difficult to maintain silence during the information acquisition process, which can compromise the confidentiality of communications. The present invention proposes a silent communication system that obtains information without visual or auditory means, so that the information receiver does not obtain information in the form of pictures, text, audio or video, etc. At the same time, the information sender can send information content in the form of actions, pictures, text, audio or video, etc., and no sound or light signals are emitted during the information acquisition process. It is not restricted by spatial distance and has good silent effect and confidentiality, so that the information sender and the information receiver can send and receive information more accurately in scenarios where they cannot obtain information by using visual or auditory functions.
