Detailed Description
The technical scheme of the invention is clearly and completely described below by combining the embodiment and the attached drawings of the specification. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It has been found that meditation training comprises four sequential phases, namely four states: active state, quiet state, relaxed state, and fixed state. The meditation degree corresponding to the active state to the entering state gradually increases. However, when the user performs the meditation training, it is difficult to perform four states at a time, that is, when the user performs the meditation training, the meditation training is interrupted by other things, and then when the user continues the meditation training again, the user often cannot know which state the user should start from, and thus cannot continue the interrupted meditation training.
In order to solve the technical problems, the invention provides a method and a device for controlling interrupted meditation sound effect based on electroencephalogram signals, which solve the problem that meditation training cannot be continued once meditation training is interrupted in the prior art. In the specific implementation, the meditation state and the interruption time corresponding to the meditation training interruption of the user are recorded, and when the user continues the meditation training again, the guidance sound effect corresponding to the meditation state at the time of interruption is played. And then recording the electroencephalogram signals when the user continues to perform meditation training, and sending out a prompt sound effect according to the electroencephalogram signals. The present invention can help the user to quickly enter the meditation state before interruption to smoothly complete the whole meditation training, thereby improving the effect of the meditation training.
For example, as shown in fig. 2, the abscissa of the rectangular coordinate system is the time corresponding to the user performing meditation training, the ordinate is the intensity of the electroencephalogram signal generated when the user performs meditation training, the time corresponding to the origin of coordinates is 0, and the intensity of the electroencephalogram signal is also 0. As shown in fig. 2, when the user interrupts the meditation training at time N, the meditation state of the user is a calm state, and the period T0-N is interrupted. When the user continues the meditation training again, the guide sound effect corresponding to the calm state is played to guide the user to rapidly enter the calm state, and the time for playing the guide sound effect is T0-N. And then stopping playing the guiding sound effect, and leading the user to independently perform meditation training. And acquiring the electroencephalogram signals after the interruption of the user after T0 time, and sending out a prompting sound effect for judging whether the meditation training meets the standard or not according to the electroencephalogram signals.
Exemplary method
The method for controlling interrupted meditation sound effect based on electroencephalogram signals can be applied to terminal equipment, and the terminal equipment can be terminal products with video or audio playing functions, such as televisions, computers, mobile phones and the like. In this embodiment, as shown in fig. 1, the method for controlling interrupted meditation sound effect based on electroencephalogram specifically includes the following steps:
s100, the corresponding meditation state when the user starts to interrupt the meditation training and the interrupt time for interrupting the meditation training are obtained.
The meditation states in this embodiment include an active state, a calm state, a relaxed state, and an entry state, and the meditation degrees corresponding to the active state, the calm state, the relaxed state, and the entry state are sequentially increased.
As shown in fig. 2, the user interrupts the meditation from time N and continues the meditation again at time T0, which is the time T0-N.
S200, when the user continues to perform the meditation, obtaining a guiding sound effect corresponding to the meditation state according to the meditation state.
S300, obtaining playing time corresponding to the playing of the guide sound effect according to the interruption time.
The guidance sound effect in steps S200 and S300 corresponds to the meditation state before the interruption, and in the present embodiment, when the meditation state at the time of the interruption is the active state, the first guidance sound effect corresponding to the active state is played when the meditation training is performed again to guide the user to the extent of the active state that should be reached if the interruption is not made. For example, if the user does not interrupt the meditation training, the intensity of the electroencephalogram signal at time T0 should be a, and now the user interrupts the meditation training, so it is necessary to play the first guidance sound effect during the time T0-N to make the intensity of the electroencephalogram signal of the user reach a (if the degree of the active state that should be reached is not interrupted) during the time T0.
Similarly, when the meditation state at the time of interruption is a calm state, the second guide sound effect corresponding to the calm state is played when the meditation training is performed again; when the interrupted meditation state is a relaxation state, playing a third guide sound effect corresponding to the relaxation state when the meditation training is performed again; when the interrupted meditation state is the entering-timing state, the fourth guidance sound corresponding to the relaxation state is played when the meditation training is performed again.
In this embodiment, the volumes corresponding to the first guiding sound effect, the second guiding sound effect, the third guiding sound effect and the fourth guiding sound effect are gradually reduced, and gradually favor to light music, so that the purpose of guiding is to avoid the situation that the too large volume interferes with the quiet environment required for the meditation of the user.
In this embodiment, the playing time may be equal to the interruption time, and the playing time may also be greater than the interruption time. When the playing time is equal to the interruption time, the user can just be guided to the meditation state that should be reached if not interrupted. When the playing time is longer than the interruption time, the effect of the whole meditation training process can be improved.
In order to correctly identify whether the meditation training users before and after interruption are the same person and only the same person plays the guidance sound effect corresponding to the meditation state before interruption, the method for identifying whether the acquired electroencephalogram signals are the same meditation training user comprises the following steps:
acquiring an electroencephalogram signal of a meditation training user.
And (II) denoising the electroencephalogram signal to obtain a denoised electroencephalogram signal.
And (III) screening the de-noised electroencephalogram signal according to a preset band-pass filter algorithm to obtain a filtered electroencephalogram signal.
And (IV) learning the filtering electroencephalogram signal according to a preset convolutional neural network algorithm, and extracting a spatial filtering characteristic data set of the filtering electroencephalogram signal.
And (V) extracting the brain print characteristics of the meditation training user according to the spatial filtering characteristic data set of the filtering electroencephalogram signals.
And (VI) identifying the meditation training users according to the brain print characteristics.
And S400, collecting the electroencephalogram signals of the user after the playing time, and recording the electroencephalogram signals as the electroencephalogram signals after interruption.
As shown in fig. 2, the time after T is the time after the playing time, that is, the electroencephalogram signal after T is the electroencephalogram signal after interruption. In the embodiment, the electroencephalogram signals of the user are acquired through the device worn on the head, the electroencephalogram signals in the embodiment are the electroencephalogram signals after noise is removed, and only the electroencephalogram signals after the noise is removed can really reflect the meditation state of the user.
S500, obtaining a prompt sound effect matched with the electroencephalogram signals after interruption according to the electroencephalogram signals after interruption, wherein the prompt sound effect is used for meditation training.
In the embodiment, the electroencephalogram signal after interruption is compared with the electroencephalogram standard signal, and a prompt sound effect is obtained according to the difference between the electroencephalogram signal and the electroencephalogram standard signal.

and S501, acquiring the electroencephalogram standard signal corresponding to the time after the playing time, and recording the electroencephalogram standard signal as the electroencephalogram standard signal of the next section.
In this embodiment, the electroencephalogram standard signal in the latter period is the electroencephalogram standard signal after T time as shown in fig. 2.
S502, when the difference value between the electroencephalogram signal after interruption and the electroencephalogram standard signal at the next section is larger than a first set value, a first prompt sound effect in the prompt sound effects is obtained.
S503, when the difference value between the electroencephalogram signal after interruption and the electroencephalogram standard signal of the next section is smaller than a second set value, obtaining a second prompt sound effect in the prompt sound effects.
Whether the electroencephalogram signal after interruption exceeds a certain range when being larger than the electroencephalogram standard signal or exceeds a certain range when being smaller than the electroencephalogram standard signal, the meditation effect of the user who carries out meditation training at the moment is not ideal, and corresponding prompt sound effect needs to be sent out to inform the user of the training effect at the moment, so that the user can adjust himself in time.
The step 500 not only can reflect the meditation training effect of the user according to the difference value between the electroencephalogram signal after interruption and the electroencephalogram standard signal, but also can send out a prompt sound effect according to the curves corresponding to the two signals. When the cue sound effect is issued according to the curve, the step S500 includes the following steps S504, S505, S506, S507:
and S504, acquiring the electroencephalogram standard signal corresponding to the time after the playing time, and recording the electroencephalogram standard signal as the electroencephalogram standard signal of the next section.
And S505, drawing a curve by the time corresponding to the electroencephalogram standard signal of the next section and the electroencephalogram standard signal of the next section, and recording the curve as the electroencephalogram standard curve of the next section.
In this embodiment, the standard curve of the brain wave in the latter period is the curve after T time as shown in fig. 2.
S506, drawing a curve of the electroencephalogram signal after interruption and the time corresponding to the electroencephalogram signal after interruption, and recording the curve as an electroencephalogram curve.
And S507, obtaining a prompt sound effect according to the matching degree between the electroencephalogram curve and the electroencephalogram standard curve of the next section.
In this embodiment, when the trend of the electroencephalogram curve is the same as the trend of the electroencephalogram standard curve (both curves are increasing or decreasing at the same time), a prompt sound effect that the training is qualified is sent out, otherwise, a prompt sound effect that the training is unqualified is sent out.
In the embodiment, the instantaneous meditation training effect of the user can be judged according to the strength of the electroencephalogram signals, and the whole meditation training process of the user can be evaluated. When the process of the entire meditation training is evaluated, the following steps S601, S602, S603, S604, S605, S606 are included:
s601, acquiring the electroencephalogram signals of the user before interruption of the meditation training, and recording the electroencephalogram signals as the electroencephalogram signals before interruption.
And S602, acquiring the electroencephalogram standard signal corresponding to the time before interruption of the meditation training, and recording the electroencephalogram standard signal as the electroencephalogram standard signal of the previous section.
And S603, acquiring the electroencephalogram standard signal corresponding to the time after the playing time, and recording the electroencephalogram standard signal as the electroencephalogram standard signal of the next section.
S604, calculating the difference between the electroencephalogram signal before interruption and the electroencephalogram standard signal of the previous section, and recording as a first difference.
S605, calculating the difference value between the electroencephalogram signal after interruption and the electroencephalogram standard signal of the next section, and recording as a second difference value.
S606, obtaining an evaluation sound effect according to the first difference value and the second difference value.
In steps S601-S606, the difference between each instantaneous electroencephalogram signal and an electroencephalogram standard signal is counted, then an average value is calculated, the average value before interruption is used as a first difference value, and the average value after interruption is used as a second difference value. Then, according to the first difference and the second difference, calculating the average value of the two differences, taking the average value as a final average value, and if the final average value is large, sending out an evaluation sound effect that the meditation training is unqualified; if the final average value is small, the evaluation sound effect of the passing of the meditation training is sent out.
In summary, the present invention firstly records the meditation status corresponding to the interrupted meditation training of the user, and when the user continues the meditation training again, the user sends out the guidance sound corresponding to the meditation status at the interrupted time, and the guidance sound can inform the user of the meditation status corresponding to the interrupted meditation training, and can help the user to quickly enter the meditation status before the interruption, so as to smoothly complete the whole meditation training, thereby improving the effect of the meditation training. In addition, the invention collects the electroencephalogram signals of the interrupted users after the users continue to carry out meditation training, and sends out prompt sound effects according to the intensity of the electroencephalogram signals, wherein the prompt sound effects are used for informing the users about the meditation training, so that the users can know the meditation training effect of the users, and if the meditation training effect does not meet the requirements, the users can adjust the users according to the prompt sound effects to improve the meditation training effect.
