[0049] The following is a clear and complete description of the technical solution of the present invention in combination with the embodiments and the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Research has found that when conducting attention training, it is first necessary to evaluate the user's attention and select a training method suitable for the user based on the evaluation results. The existing technology often uses the observation of the user's facial micro-expressions to judge the user's attention level. This method of judging the user's attention level through subjective consciousness has poor accuracy, and different observers will obtain different evaluation results for the same user.

[0051] In order to solve the above technical problems, the present invention provides an attention assessment method, device, equipment and storage medium, which solves the problem of low accuracy of attention assessment results in the prior art. In specific implementation, the user's attention level is assessed based on the instantaneous brain wave reference signal corresponding to the user's instantaneous brain wave signal, and the assessment result obtained by the present invention has high accuracy.

[0052] For example, Figure 2 As shown in the figure, the horizontal axis is the time of attention training, the vertical axis is the signal strength, and there are two curves, one of which is the EEG signal curve of the user to be evaluated, and the other is the curve of the EEG reference signal. The EEG reference signal is the EEG signal that can be used as a reference standard. Figure 2 It can be seen that at instant t1, the gap between the EEG signal of the user to be evaluated and the EEG reference signal is small, while at instant t2, the gap between the EEG signal of the user to be evaluated and the EEG reference signal is small. Therefore, the concentration of the user to be evaluated at instant t2 is greater than that at instant t1.

[0053] Exemplary Methods

[0054] The attention evaluation method of this embodiment can be applied to a terminal device, which can be a terminal product with an audio playback function, such as a television, a computer, a mobile phone, etc. Figure 1 As shown in , the attention evaluation method specifically includes the following steps:

[0055] S100, obtaining brain wave signals corresponding to each instant of the user to be evaluated.

[0056] The instant in this embodiment refers to a short time, for example, the instant can be two seconds or three seconds. When collecting the brain wave signal of the user to be evaluated, the brain wave signals of each instant of the user to be evaluated in a quiet environment and the brain wave signals of the user to be evaluated in a noisy environment can be collected respectively. Compare the brain wave signals of each instant in the quiet environment with the brain wave reference signal to obtain the first gap between the two at each instant; compare the brain wave signal in the noisy environment with the brain wave reference signal to obtain the second gap between the two at each instant. Calculate the difference between the first gap and the second gap, and the difference is used to characterize the stability of the concentration of the user to be evaluated in different environments. The larger the difference, the worse the stability, and the smaller the difference, the better the stability. According to the difference, the attention of the user to be evaluated can be further evaluated.

[0057] S200, comparing the brain wave signal corresponding to each instant with the brain wave reference signal corresponding to each instant to obtain a comparison result.

[0058] This embodiment includes two cases. The first case: the average value of the signal in the time period of the instant is taken as the instantaneous brain wave signal of the user to be evaluated, and the average value is compared with the brain wave reference signal; the second case: the duration of the abnormal difference between the brain wave signal in the time period of the instant and the brain wave reference signal, and the comparison result is obtained according to the duration. In the first case, the overall concentration of the user to be evaluated at the instant can be known; in the second case, the stability of the attention of the user to be evaluated can be known.

[0059] In the first case, step S200 includes the following steps:

[0060] S201, according to each of the instants, obtaining a time period corresponding to each of the instants.

[0061] For example, if the instant is the third minute, the time period corresponding to the instant is the third minute.

[0062] S202, obtaining a brain wave signal corresponding to the time period according to the time period.

[0063] The moment is the third minute, and the corresponding time period is all the brain wave signals within the third minute.

[0064] S203, calculating an average value of the brain wave signal in the time period according to the brain wave signal corresponding to the time period.

[0065] Count all the brain wave signals in the third minute, calculate the average value of all the brain wave signals in this minute, and use the average value as the brain wave signal of the third minute.

[0066] S204, comparing the average value at each instant with the brain wave reference signal corresponding to each instant to obtain a comparison result.

[0067] In this embodiment, Figure 2 As shown, since the EEG reference signal is generated by users with better concentration, the EEG reference signal can basically maintain a fixed value in a short period of time, so there is no need to average the instantaneous EEG reference signal.

[0068] The comparison result in this embodiment is the difference between the average value and the brain wave reference signal.

[0069] In the second case, step S200 includes the following steps:

[0070] S205: Obtain a time period corresponding to each of the instants according to each of the instants.

[0071] S206: Obtaining a brain wave signal corresponding to the time period according to the time period.

[0072] S207, based on the brain wave signal corresponding to the time period, counting the duration for which the difference between the brain wave signal and the brain wave reference signal in the time period is continuously greater than the set value.

[0073] For example, if the difference between the brain wave signal from the tenth to the twentieth second in the second minute and the brain wave reference signal is greater than the set value, then during the tenth to the twentieth second in the second minute, the attention of the user to be evaluated is not good. The duration in this embodiment is the ten seconds corresponding to the tenth to the twentieth second, and the attention of the other fifty seconds is good.

[0074] S208: Obtain a comparison result according to the duration.

[0075] In this embodiment, the duration is used as the comparison result.

[0076] S300, obtaining an evaluation result according to the comparison result, wherein the evaluation result is used to characterize the attention level of the user to be evaluated at each moment.

[0077] When step S200 is the first case, step S300 includes: according to the comparison result, obtaining the degree of fit between the average value of each instant in the comparison result and the brain wave reference signal corresponding to each instant, wherein the degree of fit is used to characterize the similarity between the average value and the brain wave reference signal.

[0078] The degree of agreement in this embodiment is the difference between the average value and the brain wave reference signal.

[0079] When step S200 is the second case, step S300 includes the following steps S301 and S302:

[0080] S301, when the duration in the comparison result is less than the set time, the instantaneous attention level of the user to be evaluated in the evaluation result is obtained as level one.

[0081] S302, when the duration in the comparison result is greater than the set time, the instantaneous attention level of the user to be evaluated in the evaluation result is obtained as level two, and the level two instantaneous attention level is less than the level one instantaneous attention level.

[0082] For example, if the difference between the brain wave signal from the tenth second to the twentieth second in the second minute (instantaneous) and the brain wave reference signal is greater than the set value, then the duration in the second minute is ten seconds, and the set time is artificially set, and the set time can be fifteen seconds. Ten seconds in this embodiment is less than fifteen seconds, so the instantaneous attention level of the user to be evaluated is level one.

[0083] In this example, the brain wave signal of the user to be evaluated is collected by the device. There are delays in the device collecting and transmitting signals. For example, the device shows that the brain wave signal of the user to be evaluated at the fifth second is a. However, due to the delay problem of the device, the brain wave signal a does not correspond to the fifth second. If the brain wave signal a is used to evaluate the concentration level of the user to be evaluated at the fifth second, the evaluation result obtained cannot represent the concentration level of the user to be evaluated at the fifth second.

[0084] Therefore, in order to avoid the above problems, this embodiment adopts the following steps S401, S402, S403, S404, S405 to obtain each instantaneous evaluation result of the user to be evaluated.

[0085] S401, plotting the brain wave signals of the user to be evaluated at each instant into a curve according to the time sequence corresponding to each instant, and recording it as the brain wave curve of the user to be evaluated.

[0086] S402, according to the time sequence corresponding to each instant, the brain wave reference signal at each instant is plotted into a curve, which is recorded as the brain wave reference curve.

[0087] In this embodiment, the time corresponding to the collected signal is used as the horizontal axis and the signal strength is used as the vertical axis. The curves corresponding to the brain wave signals of the user to be evaluated collected at each instant and the curves corresponding to the brain wave reference signals are plotted in the same coordinate system.

[0088] S403, moving the EEG curve by a set distance in a direction opposite to the time sequence to obtain the EEG curve after the movement, wherein the set distance corresponds to a delay time of a signal acquisition device, and the signal acquisition device is used to acquire the EEG signal of the user to be evaluated.

[0089] like Figure 3 As shown, the solid line EEG signal is the EEG signal of the user to be evaluated collected in real time, and the dotted line EEG signal is the EEG signal after moving. In this embodiment, the dotted line EEG signal is obtained by moving the solid line EEG signal to the left by a set distance along the horizontal coordinate (time coordinate). The dotted line EEG signal is the signal corresponding to each instant of the user to be evaluated. The delay time of the signal acquisition device is known, and the set distance is the delay time.

[0090] S404, comparing the EEG curve after the movement with the EEG reference curve to obtain the difference between the EEG curve and the EEG reference curve at each instant.

[0091] S405: Obtain an evaluation result according to the difference.

[0092] like Figure 3 As shown in the figure, to evaluate the concentration level of the user to be evaluated at the instant t1, the brain wave signal strength corresponding to the dotted line at t1 is used instead of the brain wave signal strength corresponding to the solid line. When calculating the evaluation result of the user to be evaluated at the instant t1, the brain wave signal strength on the dotted line at t1 is subtracted from the brain wave reference signal at t1.

[0093] After collecting each instantaneous brain wave signal of the user to be evaluated, this embodiment forms the brain wave signal of the entire attention training process by using the instantaneous brain wave signals, and then evaluates the attention of the entire process. When evaluating the attention of the entire process, the following steps S501, S502, S503, S504, and S505 are included:

[0094] S501, accumulating the comparison results corresponding to each instant to obtain an accumulation result.

[0095] S502: Obtain, according to the accumulated result, a first score corresponding to the entire process of the attention training of the user to be evaluated.

[0096] S503, counting the continuous time corresponding to the difference between the brain wave signal corresponding to each consecutive instant and the brain wave reference signal being less than a preset value.

[0097] S504, obtaining a second score according to the continuous time.

[0098] S505: Obtain a total score based on the first score and the second score, where the total score is used to represent the degree of attention during the entire process.

[0099] In summary, on the one hand, the present invention uses brain wave signals to characterize the attention of the user to be evaluated. As a physiological parameter of the user, brain waves can accurately and objectively reflect the attention of the user to be evaluated. On the other hand, the present invention compares the instantaneous brain wave signal of the user to be evaluated with the instantaneous brain wave reference signal. When the two are very close, it indicates that the user's attention level at that moment is relatively high, otherwise the attention level is relatively low. In summary, the present invention uses the user's instantaneous brain wave signal to evaluate the user's instantaneous attention level, and the evaluation result is objective and accurate.
