Description

Technical Field

[0001] The present invention relates to the technical field of multimodal signal fusion, and in particular to a TENS signal generation method, apparatus, device and medium. Background Art

[0002] Multimodal signal fusion is one of the foundations of virtual reality augmented reality technology. Currently, there are many technologies based on visual and auditory signal processing and enhancement, but the integration of tactile signals is still in the research stage. On the one hand, the introduction of tactile signals has a huge impact on human perception and can significantly enhance the experience of various virtual reality augmented reality technologies. For example, mainstream game consoles (such as X-box, Sony PlayStation, and Nintendo Switch) all include game controllers with vibration functions to enhance the player's gaming experience; video websites (such as Bilibili) use mechanical vibration combined with rhythmic videos to enhance the viewing experience. On the other hand, touch has unique applications in medicine and health care, such as using massage devices to relieve pain.

[0003] Currently, tactile stimulation can be achieved by using traditional mechanical devices such as vibration motors to simulate tactile stimulation, or by using electrical signals to simulate tactile stimulation, i.e., using the transcutaneous electrical nerve stimulation (TENS) mechanism. SKG (a wearable massager brand) has also launched a massage chair product that uses TENS stimulation. However, in the process of using the existing technology, the inventors found that the existing technology has at least the following problems:

[0004] 1) The electrical signals generated by current TENS-based products are simple periodic signals, providing a single experience;

[0005] 2) The signals generated by current TENS-based products cannot be automatically integrated with other sensory signals (such as hearing). Summary of the Invention

[0006] The present invention aims to solve the above technical problems at least to a certain extent, and provides a TENS signal generation method, device, equipment and medium.

[0007] The technical solution adopted in the present invention is:

[0008] In a first aspect, the present invention provides a TENS signal generating method, comprising:

[0013] According to the power spectrum of the electric tactile signal, amplitude modulation is performed on the multiple atomic waveforms of the electric tactile signal to obtain a TENS signal.

[0014] The present invention allows users to customize the corresponding vibration effects according to different audio signals, thereby facilitating the personalized customization of TENS signals and providing a good user experience. Specifically, during the implementation of the present invention, the audio signal is first divided into multiple audio signal frames to obtain the audio power spectra corresponding to the multiple audio signal frames. Then, the audio power spectrum is processed to obtain the tactile electric signal power spectrum corresponding to the audio power spectrum; at the same time, a tactile electric signal atomic waveform library is constructed; finally, according to the tactile electric signal power spectrum, the multiple tactile electric signal atomic waveforms are amplitude modulated to obtain the TENS signal. During this process, users can build a tactile electric signal atomic waveform library by themselves according to their requirements for the intensity of the vibration signal corresponding to the audio signal, and then fuse multiple tactile electric signal atomic waveforms in the tactile electric signal atomic waveform library with multiple audio signal frames corresponding to the audio power spectrum through amplitude modulation to generate the final TENS signal. The TENS signal can be adapted to the corresponding audio signal and tactile electric signal atomic waveform in turn. The TENS signal can change with the change of the audio signal according to the difference of the tactile electric signal atomic waveform, thereby achieving the technical effect of the fusion of touch and hearing.

[0046] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] It should be understood that the term "and / or" that may appear in this document is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B may mean: A exists alone, B exists alone, and A and B exist at the same time.

For example, depending on the functions / acts involved, they may actually be performed substantially concurrently, or two figures shown in succession may sometimes be performed in the reverse order.

[0049] Example 1:

[0050] A first aspect of this embodiment provides a TENS signal generation method, which can be executed by, but is not limited to, a computer device or a virtual machine with certain computing resources, such as a personal computer, a smart phone, a personal digital assistant, or a wearable device, or by a virtual machine, so as to achieve personalized customization of the TENS signal.

[0051] like Figure 1 As shown, a TENS signal generation method, device, equipment and medium may include, but are not limited to, the following steps:

[0052] S1. receiving an audio signal, and then dividing the audio signal into a plurality of audio signal frames;

[0053] S2 obtains the audio power spectrum corresponding to the multiple audio signal frames;

[0054] In this embodiment, obtaining audio power spectra corresponding to the multiple audio signal frames includes:

[0055] S201. Obtain power values of the plurality of audio signal frames respectively, wherein the power value of any audio signal frame is:

[0056]

[0057] Where n is the frame length of the current audio signal frame, x i is the amplitude of the i-th sampling point in the current audio signal frame; it should be understood that, in this embodiment, the power value of the audio signal frame adopts the root mean square power value, and it may also adopt the average power value. Compared with the average power value, the root mean square power value is more robust to abnormal values.

[0058] S202. Count the power values of the multiple audio signal frames to obtain audio power spectra corresponding to the multiple audio signal frames. It should be understood that the audio power spectrum is audio power density distribution data obtained by counting the multiple audio signal frames.

[0060] In this embodiment, the audio power spectrum is processed to obtain a tactile electrical signal power spectrum corresponding to the audio power spectrum, including:

[0061] Based on a specified transformation function, the audio power spectrum is subjected to function transformation processing to obtain a tactile electric signal power spectrum corresponding to the audio power spectrum;

[0062] In this embodiment, the specified transformation function can be set to one or more. When it is set to multiple, multiple specified transformation functions are combined to form a composite transformation function. It should be noted that multiple specified transformation functions can be combined to obtain a composite transformation function.

The combination order of control parameters and basic functions can be optimized according to the audio power spectrum. Based on the composite transformation function with optimized parameters and combination order, the audio power spectrum is transformed and processed to obtain the tactile electrical signal power spectrum.

[0063] It should be noted that the use of multiple specified transformation functions to perform function transformation processing on the audio power spectrum can make the power of the audio power spectrum more suitable for tactile presentation. For example, in view of the fact that the sense of touch is not as high as the hearing resolution, the power spectrum of the tactile electric signal can be adjusted to increase the dynamic range; in addition, the use of a combination of multiple specified transformation functions for transformation processing can reduce the number of parameters, making it easier to quickly design a good overall transformation function for the tactile electric signal power spectrum.

[0064] The tactile electrical signal power spectrum corresponding to the audio power spectrum is:

[0072] And / or, based on a normalized transformation function, performing normalized transformation processing on the current audio signal frame; wherein the normalized transformation function is: f4(E)=(EE min ) / (E max -E min ); where E is the audio power spectrum, E min is the maximum power value of the audio signal frame in the audio power spectrum, E max is the minimum power value of the audio signal frame in the audio power spectrum.

[0073] Specifically, in this embodiment, the designated transformation function is an exponential transformation function, a logarithmic transformation function, a linear transformation function, and a normalized transformation function.

In this embodiment, the multiple tactile electric signal atomic waveforms may be different.

[0075] S5. Based on the power spectrum of the electric tactile signal, amplitude modulate the multiple electric tactile signal atomic waveforms to obtain a TENS signal. It should be noted that amplitude modulation is used to fuse the electric tactile signal atomic waveforms with the corresponding audio signal so that the TENS signal can trigger electric signals of different intensities based on the power value of the audio signal. Of course, the intensity of the triggered electric signal depends on the corresponding electric tactile signal atomic waveform.

[0076] Specifically, according to the tactile electric signal power spectrum, after amplitude modulation is performed on the multiple tactile electric signal atomic waveforms, in the obtained TENS signal, the TENS signal value corresponding to the mth audio signal frame in the audio power spectrum is:

[0077] TENS (m) =F (m) ×A (m) ;

[0078] Among them, F (m) is the power spectrum of the tactile electric signal of the mth audio signal frame; A (m) is the mth tactile electric signal atomic waveform in the tactile electric signal atomic waveform library.

[0079] This embodiment allows users to customize the corresponding vibration effects according to different audio signals, thereby facilitating the personalized customization of TENS signals and providing a good user experience. Specifically, during the implementation of this embodiment, the audio signal is first divided into multiple audio signal frames to obtain the audio power spectra corresponding to the multiple audio signal frames.
