Description

Technical Field

[0001] The present application relates to the field of near-infrared technology, and in particular to a neural feedback training device and storage medium based on near-infrared data. Background Art

[0002] Cognitive intervention is an effective treatment for diseases related to neurodevelopmental and brain dysfunction, such as limb movement disorders and attention deficit disorder. Neurofeedback training is an important cognitive intervention method. It measures the patient's brain function and provides real-time visual and auditory feedback to the patient, allowing the patient to make autonomous adjustments based on the measurement results, thereby gradually improving and enhancing their brain function.

[0003] However, the feedback form in existing neurofeedback training is relatively simple. For example, the feedback result is only the rise and fall of an object. Patients are likely to lose interest in training after long-term training. If such a simple feedback form shows negative feedback results, patients are likely to lose confidence. In addition, the existing method only presents the feedback results of the training phase, making it difficult to judge the training effect and its authenticity. Summary of the Invention

[0004] The present application is proposed to address the above-mentioned technical problems existing in the prior art. The present application aims to provide a neurofeedback training device and storage medium based on near-infrared data, which can provide fun and controllable training tasks while introducing regular and appropriate feedback elements through a display interface, so that trainees can quickly enter the training state. The feedback is in the form of the telescopic state of the controlled body and the objects touching the controlled body are received or deformed by the telescopic controlled body, so that trainees can maintain high attention, motivation and confidence to complete the training tasks, and the feedback results of the training stage and the rest stage are presented on the display interface, so that the authenticity of the training effect can be determined, thereby improving the therapeutic effect on the trainees.

[0005] According to a first embodiment of the present application, a neurofeedback training device based on near-infrared data is provided, the neurofeedback training device including a processor configured to prompt a trainee to perform alternating training tasks and rest tasks; obtain first blood oxygen concentration data of relevant brain areas of the trainee during the training phase and second blood oxygen concentration data of relevant brain areas during the rest phase, the first blood oxygen concentration data being obtained based on the near-infrared data of the training phase acquired by a near-infrared data acquisition module, and the second blood oxygen concentration data being obtained based on the near-infrared data of the rest phase acquired by the near-infrared data acquisition module; during the training phase, a group of regularly arranged objects is presented on a display interface moving relative to a controlled body, and objects touching the controlled body are received or deformed by the retractable controlled body; the retractable state of the controlled body is presented in association with the first blood oxygen concentration data; during the rest phase, the retractable controlled body is presented on the display interface without the group of regularly arranged objects, and the retractable state of the controlled body is presented in association with the second blood oxygen concentration data.

[0006] According to a second embodiment of the present application, a computer-readable storage medium is provided, the computer-readable storage medium storing a computer program, which, when executed by a processor, causes the processor to perform the following processing: prompting a trainee to perform alternating training tasks and rest tasks; obtaining first blood oxygen concentration data of relevant brain regions of the trainee during a training phase and second blood oxygen concentration data of relevant brain regions during a rest phase, wherein the first blood oxygen concentration data is obtained based on near-infrared data collected by a near-infrared data acquisition module during the training phase, and the second blood oxygen concentration data is obtained based on near-infrared data collected by the near-infrared data acquisition module during the rest phase; during the training phase, a group of regularly arranged objects is presented on a display interface as moving relative to a controlled body, and objects touching the controlled body are received or deformed by the retractable controlled body; the retractable state of the controlled body is presented in association with the first blood oxygen concentration data; during the rest phase, the retractable controlled body is presented on the display interface without the group of regularly arranged objects, and the retractable state of the controlled body is presented in association with the second blood oxygen concentration data.

[0007] Compared with the prior art, the embodiments of the present application have the following advantages:

[0008] The neurofeedback training device provided by the embodiment of the present application provides trainees with interesting training tasks with rich feedback forms. During the training phase, a group of objects containing regularly arranged objects is presented on the display interface and moves relative to the controlled body, and the objects touching the controlled body are received or deformed by the controlled body. The training task is not only to strive to change the controlled body, but also to make the trainees change the controlled body through hard training so that more of the objects are deformed or received. After directly observing the objects touching the controlled body being received or deformed, the trainees can visually feel the results of their efforts. For example, as the objects received by the controlled body gradually accumulate in the controlled body, they will feel a great sense of satisfaction and accomplishment, and want to work harder to receive more objects. The rich feedback forms greatly increase the trainees' enthusiasm for performing the training task. Of course, when the trainees see the objects touching the controlled body deformed, they will also have a strong visual impact. The deformation of the objects will also increase the trainees' interest in performing the training task. This is conducive to keeping the trainees' attention high during the training task. The feedback results in this application include changes in the length of the controlled subject, the contact between the controlled subject and the object, and the deformation or storage of the object. In this way, even if the length of the controlled subject shows a negative change, the trainee will not completely lose confidence and interest in training due to the feedback results of the contact between the controlled subject and the object and the deformation or storage of the object. Instead, he will strive to make self-adjustments and strive to achieve better training results.

[0009] The controlled subject provided in the embodiment of the present application can be extended and retracted as the first blood oxygen concentration data rises and falls. For example, when the first blood oxygen concentration data rises, the controlled subject is extended, and when the first blood oxygen concentration data falls, the controlled subject is shortened. In this way, the first blood oxygen concentration data is presented in association with the controlled subject. At the same time, as the controlled subject is extended, the more objects that touch the controlled subject and are accommodated or deformed increase, and the greater the sense of accomplishment that the trainee can have. During the rest phase when the trainee performs a rest task, the display content on the display interface of this phase is distinguished from the display content of the training phase. The controlled subject that can be extended and retracted as the second blood oxygen concentration data rises and falls is displayed on the display interface, but the group is not displayed, and the extension and retraction state of the controlled subject is extended and retracted as the second blood oxygen concentration data rises and falls. In this way, users (such as doctors) can judge the training effect and its authenticity by comparing the stretching and contraction of the controlled subject in the rest stage and the training stage. For example, if the controlled subject does not shorten accordingly after the trainee enters the rest stage, or even stretches, the doctor can judge based on this that there is a problem with the neurofeedback training device or the trainee's status. In addition, the display interface of the rest stage does not contain objects to prevent the trainee from being unable to maintain a relaxed state due to the interference of objects when performing the rest task, thereby affecting the training effect.

In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

[0017] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and specific embodiments, but are not intended to limit the present application.

[0018] The words "first", "second" and similar terms used in this application do not indicate any order, quantity or importance, but are only used to distinguish. The words "include" or "comprises" and similar terms used in this application mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of covering other elements. In this application, the arrows shown in the figures of each step are only examples of the execution order, not limitations. The technical solution of this application is not limited to the execution order described in the embodiments. The steps in the execution order can be combined, decomposed, or swapped, as long as the logical relationship of the execution content is not affected.

[0019] All terms (including technical or scientific terms) used in this application have the same meaning as those understood by ordinary technicians in the field to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having the same meaning as they have in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense unless explicitly defined as such here. Devices known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the devices should be considered as part of the specification.

[0020] FIG1(a) shows a schematic structural diagram of a neurofeedback training device according to an embodiment of the present application. The neurofeedback training device 100 includes at least a processor 101 and a display 102, wherein the display 102 can be used to provide an interface corresponding to the execution content of the training task and rest task performed by the trainee and other tasks performed. The processor 101 is configured to execute steps S103 to S106 shown in FIG1(b). It should be noted that the processor 101 may not be configured to process in the order of steps S103 to S106, and those skilled in the art may adjust the execution order of steps S103 to S106 as needed.

[0021] In step S103, the trainee is prompted to perform alternating training tasks and rest tasks. In step S104, first blood oxygen concentration data of the trainee's relevant brain regions during the training phase and second blood oxygen concentration data of the trainee's relevant brain regions during the rest phase are obtained. The first blood oxygen concentration data is obtained based on the near-infrared data collected by the near-infrared data acquisition module during the training phase, and the second blood oxygen concentration data is obtained based on the near-infrared data collected by the near-infrared data acquisition module during the rest phase. The training tasks can be configured based on the trainee's disease type. For example, if the trainee has a limb movement disorder, the training task can be imagining limb movements, such as imagining continuous grasping with the left or right hand. If the trainee has attention deficit disorder, the training task can be focusing attention and imagining a change in the subject, such as imagining the subject lengthening. This is not specifically limited and can be selected or configured by the physician based on the trainee's disease type. The rest task can require the trainee to remain relaxed, but other methods of performing the rest task are not excluded.

[0022] The first blood oxygen concentration data and the second blood oxygen concentration data may be the relative changes in oxyhemoglobin, deoxyhemoglobin, or total hemoglobin in the relevant brain region determined from near-infrared data collected by an external near-infrared data acquisition device or a built-in near-infrared data acquisition module. Preferably, the relative change in oxyhemoglobin concentration is used. If the trainee has a limb movement disorder, the relevant brain region may be the trainee's left and right motor brain regions and / or the S1 primary trunk sensory cortex, wherein the left and right motor brain regions include at least the M1 primary motor cortex. If the trainee has an attention deficit disorder, the relevant brain region may be the trainee's frontal lobe, preferably the trainee's dorsolateral prefrontal lobe.

[0023] In this embodiment, the near-infrared data acquisition module can be integrated into the neurofeedback training device 100 to respectively collect the near-infrared data of the trainee during the training phase and the rest phase. After the near-infrared data is collected, it is analyzed and processed to obtain the first blood oxygen concentration data and the second blood oxygen concentration data, respectively.

[0024] In addition, the neurofeedback device 100 may further include an interface (not shown), and an external near-infrared data acquisition device may be used in conjunction with the neurofeedback training device 100. The neurofeedback training device 100 obtains the first blood oxygen concentration data and the second blood oxygen concentration data based on the interface. Figure 2As shown, a near-infrared data acquisition device 202 can be used to collect near-infrared data of the relevant brain areas. The near-infrared data acquisition device 202 has at least a head cap 201, and the head cap 201 is used to be worn on the head of the trainee. For example, the head cap 201 can have multiple probes for transmitting near-infrared light and / or receiving near-infrared light. Each of the multiple probes can be configured as a transmitting probe (S) or a receiving probe (D), and each pair of probes arranged in pairs can form a detection channel. In some embodiments, one transmitting probe can correspond to multiple receiving probes, or conversely, one receiving probe can correspond to multiple transmitting probes, and the pairing relationship is determined according to the specific requirements of the probe's layout position, the brain functional area to be detected, etc.

[0025] The near-infrared data acquisition device 202 or other devices used in conjunction therewith can be used to collect near-infrared data of relevant brain areas when the trainee performs training tasks and rest tasks, thereby obtaining near-infrared data of the trainee when performing training tasks and rest tasks.

[0026] The interface can transmit information and may include, but is not limited to, a network adapter, a cable connector, a serial connector, a USB connector, a parallel connector, a high-speed data transmission adapter, such as an optical fiber, USB 3.0, Thunderbolt, etc., a wireless network adapter, such as a WiFi adapter, a telecommunications (3G, 4G / LTE, etc.) adapter, etc. In some embodiments, the interface can be a network interface, and the neurofeedback training device 100 can be connected to a network, such as, but not limited to, a local area network or the Internet, through the interface.

[0027] The neurofeedback training device 100 in this embodiment may also include a speaker (not shown) that provides voice prompts to the trainee regarding the content of the training and rest tasks to be performed. In this way, the trainee can quickly familiarize themselves with the tasks and quickly enter the training state through the voice prompts and the animations displayed on the display interface.

[0028] In step S105, during the training phase, a group of regularly arranged objects is presented on the display interface as moving relative to a controlled subject. Objects touching the controlled subject are accommodated or deformed by the retractable controlled subject. The retractable state of the controlled subject is presented in association with the first blood oxygen concentration data. The controlled subject can retract or shrink based on the rise and fall of the first blood oxygen concentration data. For example, if the first blood oxygen concentration data rises as the trainee performs a training task, the controlled subject will lengthen as the first blood oxygen concentration data rises. If the first blood oxygen concentration data falls as the trainee performs the training task, the controlled subject will shorten as the first blood oxygen concentration data falls. In other words, the retractable state of the controlled subject is presented in association with the first blood oxygen concentration data, which can intuitively reflect the changes in the first blood oxygen concentration data of the trainee as the trainee performs the training task.

[0029] The technical solution of this application can provide trainees with a timely, intuitive, and clear linkage mechanism of their training performance relative to the controlled subject. Simply put, if the training performance is good, the controlled subject will perform an extension action; more objects will touch the controlled subject and be accommodated or deformed. In this way, the display interface introduces a regular and appropriate feedback element for the controlled subject-object group, providing trainees with real-time dynamic feedback (good training performance - controlled subject extension) and cumulative dynamic feedback (more objects are accommodated or deformed), providing more comprehensive and rich feedback information. Moreover, the scene of the controlled subject stretching - more objects being stored or deformed - is easy for trainees of all cognitive levels to associate with familiar real-life scenes (such as rolling out dough for children and storing gems for the elderly, which will be described in detail below). It is not only effortless to understand, but also cleverly hits the unique interests of children and the elderly. Children like to get a sense of control and accomplishment by deforming objects (such as playing with sand and kneading plasticine), while the elderly like to get a sense of control and accomplishment by hoarding or storing objects (such as hoarding old items, tableware, etc.). These two groups of people are happy to do these behaviors and believe that they are more confident in doing them. Young and middle-aged individuals between children and the elderly usually have a strong interest in object deformation and storage. This application provides fun and controllable training tasks and feedback information so that trainees can quickly enter the training state. Even if the length of the controlled subject becomes shorter, the trainees will not completely lose confidence and interest in training due to the contact between the controlled subject and the object and the deformation or storage of the object. Instead, they will strive to adjust themselves, strive to achieve better training results, and maintain high attention, motivation and confidence to complete the training.

[0030] On the display interface of the display 102, a group containing regularly arranged objects is also presented, and the group moves relative to the animation of the controlled subject. Among them, the objects and the controlled subject can be configured according to the type of the animation, such as the animation can be mine car treasure hunting, the objects can be gems, and the controlled subject can be a mine car; the animation can be rolling dough, the objects can be dough, and the controlled subject can be a rolling pin; the animation can be picking apples, the objects can be apples, and the controlled subject can be a fruit basket, and so on. The specific types of the objects and the controlled subject are not limited, as long as the animation formed by the objects and the controlled subject is adapted to the training task.

[0031] The objects are taken as gems, and the controlled subject is taken as a mine car as an example for description, but the application is not limited thereto.

[0032] On the display interface of the display 102, a regularly arranged gem array composed of gems of different colors is presented, the row spacing between each row of the gem array is within a threshold row spacing range, and the column spacing between each column is within a threshold column spacing range, so that the spacing between each row and each column of the gem array is not too narrow or too wide. Specifically, the mine car is configured below the gem array, and the gem array falls towards the direction where the mine car is located, wherein the speed at which the gem array moves downward does not exceed a threshold moving speed, so as to prevent the mine car from being unable to accommodate more gems due to the too fast falling speed of the gem array, thereby reducing the self-confidence of the trainee. Or, the trainee will also lose confidence in training due to the too slow falling speed of the gem array, which causes the mine car to be unable to timely accommodate the gems. Therefore, on the display interface, the speed at which the group moves towards the controlled subject does not exceed the threshold moving speed range, which can effectively maintain the self-confidence of the trainee in performing the training task.

[0033] As the first blood oxygen concentration data rises, the mine car is elongated, and at the same time, the gem array moves towards the mine car, and the gems touching the mine car are accommodated into the mine car. Of course, as the mine car is elongated, the entrance of the mine car becomes larger, and the number of gems accommodated by the mine car increases at the same time. The trainee sees that the number of accommodated gems in the mine car increases, which will obtain a greater sense of achievement and satisfaction, which is conducive to enabling the trainee to maintain a higher self-confidence and attention to continue to complete the training task.

[0034] In another embodiment, where the object is dough and the controlled entity is a rolling pin, a regularly arranged array of dough moves toward the rolling pin. As the dough array falls, the dough contacts the rolling pin, flattening and deforming. As the first blood oxygen concentration data increases, the rolling pin extends. As the rolling pin extends, the amount of dough contacted and deformed increases. As the trainee performs the training task, their effort in deforming the dough increases, making the task more engaging and boosting their confidence and sense of accomplishment.

[0035] In some embodiments, the position of the controlled subject remains unchanged, and at the start of the training phase, the group of regularly arranged objects is at a preset distance from the controlled subject, and the group moves toward the controlled subject. In this embodiment, the controlled subject does not come into contact with the objects at the beginning of training, but is at a preset distance from the group. This is because the trainee's first blood oxygen concentration data has a certain rising period compared to other physiological data such as EEG signals. The first blood oxygen concentration data generally reaches a higher value some time after the trainee starts to perform a training task. Therefore, at the start of the training phase in this application, the group of regularly arranged objects is at a preset distance from the controlled subject to prevent the controlled subject from being unable to come into contact with more objects due to the slow rise of the first blood oxygen concentration data, thereby reducing the trainee's training confidence.

[0036] In step S106, during the rest phase, the retractable controlled subject is presented on the display interface and the group of regularly arranged objects is not presented, and the retractable state of the controlled subject is presented in association with the second blood oxygen concentration data. That is, on the display interface of the display 102, the group of regularly arranged objects is no longer displayed, but only the retractable controlled subject is displayed. For example, during the training phase of a training task, the objects are gems, and the controlled subject is a mine cart. The gem array moves toward the mine cart while the trainee is performing the training task, and the gems are collected by the mine cart after touching the mine cart. After the training task is completed, the rest phase of the rest task is entered. At this time, the gem array on the display interface disappears, and only the retractable mine cart is presented.

[0037] After the trainee enters the rest phase, the second blood oxygen concentration data of the relevant brain area decreases. At this time, the acquired second blood oxygen concentration data decreases, and the controlled body correspondingly shortens. In other words, the contraction and expansion of the controlled body are displayed in relation to the second blood oxygen concentration data. During the rest phase, the display interface only displays the controlled body, without the group of regularly arranged objects. This allows the trainee to see only the controlled body on the display interface without the interference of other objects, allowing them to maintain a more relaxed state and avoid continuing the training task during the rest phase.

[0038] Doctors can determine the trainee's current physiological condition by observing changes in the controlled body displayed on the interface during the rest phase. They can also assess the effectiveness of training and the authenticity of the training effect by observing changes in the length of the controlled body between the training and rest phases. For example, if a trainee completes a training task and then enters the rest phase to perform a rest task, the second blood oxygen concentration data will decrease with the end of the training task and the beginning of the rest task. Accordingly, the controlled body will shrink and shorten from its original length. However, if the controlled body does not shorten accordingly after the trainee enters the rest phase, or even lengthens, the doctor can determine that there may be a problem with the neurofeedback training device 100 or the trainee's current physiological condition, necessitating a manual review of the neurofeedback training device 100 or further analysis of the trainee's current physiological condition. Alternatively, this may be because the trainee's first blood oxygen concentration data was already relatively low during the training task, while the second blood oxygen concentration data did not decrease, or the difference between the second blood oxygen concentration data and the first blood oxygen concentration data was small, in which case the trainee's training effect may be poor.

[0039] In this way, as the object touches the controlled body and is received or deformed by the controlled body, the trainee can intuitively see the accumulation of the number of objects in the controlled body or the deformation. This intuitive picture can give the trainee a greater sense of accomplishment and satisfaction, and can maintain a high level of self-confidence in performing the training task. Moreover, the trainee performs alternating training tasks and rest tasks. When performing the rest task, the doctor can evaluate the trainee's current physiological condition or determine whether the neurofeedback training device 100 has malfunctioned based on the stretching and contraction state of the controlled body when the trainee performs the rest task, so that the doctor can adjust the training task in a timely manner or check the neurofeedback training device 100.

[0040] In some embodiments of the present application, the processor 101 is further configured to cause the center of the controlled subject presented on the display interface to deviate from the center of the group containing the objects, and the deviation distance is less than half of the distance between two adjacent objects; the controlled subject changes its telescopic state by telescoping to both sides at the same time. Specifically, Figure 3Taking the animation of a mine cart searching for gems as an example, a group 303 consisting of gems 302 is presented on the display interface 301, and the group 303 moves toward the mine cart 304. The mine cart 304 stretches as the trainee's first blood oxygen concentration data increases while performing the training task. As the mine cart 304 stretches, the entrance of the mine cart 304 becomes wider, making it easier to accommodate more gems 302. As the group 303 falls downward, the gems 302 that touch the mine cart 304 are accommodated. In this embodiment, the controlled body changes its telescopic state by simultaneously stretching to both sides, for example Figure 3 The mine cart 304 can be centered around its centerline a, which remains stationary, and then extended and retracted from the centerline b. If the centerline a of the mine cart 304 coincides with the centerline b of the group 303, the simultaneous extension and retraction of the mine cart 304 could result in the trainee being unable to reach any of the rows of gemstones 302 if the mine cart 304 is too short. This could lead to the trainee feeling frustrated after trying hard but failing to obtain a gemstone 302, and thus losing confidence in completing the training task. To this end, the centerline a of the mine cart 304 is offset from the centerline b of the group 303, meaning that the centerlines a of the mine cart 304 and b of the group 303 do not coincide. Moreover, the deviation distance between the center line a of the mine cart 304 and the center line b of the group 303 is less than half of the distance between two adjacent gems 302. In this way, it can be ensured that when the group 303 moves toward the mine cart 304, one side of the mine cart 304 can first contact the gems 302, which is beneficial for the trainees to collect at least one row of gems 302 with a little effort when performing the training task, and can effectively maintain the trainees' confidence in performing the training task.

[0041] In some embodiments of the present application, the processor 101 is further configured to present, on the display interface before the training phase, a training animation that matches the operational content of the training task to be performed by the trainee, so that the trainee performs the training task based on the training animation. By performing the training task, the trainee can activate the relevant brain areas, so that after the relevant brain areas of the trainee are activated, performing the training task can achieve better treatment effects.

[0042] For example, before performing a practice task, the trainee may be asked to perform a resting-state task. During this process, the trainee remains relaxed. The near-infrared data acquisition module collects resting-state near-infrared data from relevant brain regions of the trainee, and resting-state blood oxygen concentration data is obtained based on the resting-state near-infrared data. During this process, a representative value of the resting-state blood oxygen concentration data can be determined based on the average value of the resting-state blood oxygen concentration data over a preset period of time while the trainee performs the resting-state task.

[0043] After completing the resting-state task, the practice task is started based on the practice animation presented on the display interface, and the near-infrared data acquisition module is used to collect the near-infrared data of the relevant activated brain areas of the trainee, and the third blood oxygen concentration data is obtained based on the near-infrared data. In the first area of ​​the display interface of the practice task, a group of regularly arranged objects moves relative to the controlled subject, and the controlled subject is dynamically extended and retracted within a predetermined extension range without being associated with the third blood oxygen concentration data of the trainee's practice task, and the controlled subject in the current extension state touches the object to accommodate the touched object or deform it. In a specific embodiment, as Figure 4 As shown, the first area M of the display interface 401 on which the trainee performs the training task displays an animation of a group 403 containing objects 402 moving toward a mine cart 404. The group 403 still moves toward the mine cart 404. However, the extension and contraction of the mine cart 404 is not related to the third blood oxygen concentration data and no longer changes accordingly based on the change in the third blood oxygen concentration data. Instead, it is a pre-set animation effect, which is used to let the trainee know in advance that the mine cart 404 will show extension and contraction changes during the training process, and the extension and contraction of the mine cart 404 corresponds to the number of objects 402 that can be touched. Because trainees' medical conditions vary, if the extension and retraction of the mining cart 404 is linked to the third blood oxygen concentration data during the training task, and if the length of the mining cart 404 does not change significantly during the training task, the trainee cannot clearly perceive the feedback resulting from their hard work or lack of effort. For example, if the length of the mining cart 404 cannot be extended or the change in length is minimal due to a trainee's severe condition, the trainee may lose confidence in the training phase, become passive, or even refuse to cooperate with the training, thus reducing the training effect. The mining cart 404 dynamically retracts and retracts within a predetermined extension range, which can be set by default in the neurofeedback training device 100 or by a physician. This allows the trainee to perform the training task and intuitively see the group 403 moving toward the mining cart 404 and the object 402 touching the mining cart 404 being retracted or deformed.

[0044] In a preferred embodiment, during this process, a third representative blood oxygen concentration data value may be determined (or directly used) based on an average value of the third blood oxygen concentration data during a preset time period while the trainee performs the training task. The obtained third representative blood oxygen concentration data value is compared with the representative resting blood oxygen concentration data value. When the deviation of the third representative blood oxygen concentration data value from the representative resting blood oxygen concentration data value exceeds a threshold, it is determined that the trainee has a high degree of activation in the relevant brain region and is ready to enter the training phase of the training task.

[0045] In some other embodiments of the present application, when the trainee is a patient with limb movement disorder, the processor 101 is further configured to present a limb animation guiding the trainee to practice in the second area of ​​the display interface of the practice task, and the movement changes of the limb animation correspond to the extension and contraction changes of the controlled body. Figure 4 As shown, in the second area N, a limb animation is presented to guide the trainee's practice. This limb animation is a hand grasping movement. As the hand grasps, the mine cart 404 extends, and as the hand opens, the mine cart 404 shortens, so that the changes in the limb animation correspond to the expansion and contraction of the mine cart 404. This intuitively presents the trainee with the correlation between the hand grasping movement and the expansion and contraction of the controlled subject, encouraging the trainee to focus their attention on imagining the hand grasping movement and thus hoping to acquire more objects 402 through effort. In another specific embodiment, if the trainee has attention deficit disorder, the animation guiding the trainee's practice may not be presented on the display interface 401 while the trainee is performing the practice task.

[0046] In other embodiments of the present application, the controlled subject moves left and right within a predetermined range during the telescopic process. Furthermore, during this movement, the center of the controlled subject, as displayed on the display interface of the trainee's training or practice task, still satisfies the position requirement that the center of the controlled subject deviates from the center of the group containing the objects by less than half the distance between two adjacent objects. This further enhances the fun of the practice or training task, thereby increasing the trainee's interest and attention in performing the training task.

[0047] In some other embodiments of the present application, the processor 101 is further configured to, at least during the training phase, on the display interface, set the minimum set length of the controlled subject to be greater than or equal to the length of a single object in the group, and the controlled subject can touch at least one object in each row of objects in the group. For example, taking the object as dough and the controlled subject as a rolling pin as an example, the minimum set length of the rolling pin is not less than the length of one dough ball. In this way, when the group of dough balls moves toward the rolling pin, the minimum set length of the rolling pin is equal to the length of the dough balls, and the relative position of the controlled subject and the object can be set so that the controlled subject can at least touch at least one dough ball in each row of dough balls, thereby enabling the trainee to maintain sufficient self-confidence to perform the training task.

[0048] In some other embodiments of the present application, the processor 101 is further configured so that, at least during the training phase, on the display interface, when the length of the controlled subject is the minimum set length, the controlled subject only touches one object in each row of objects in the group. In other words, when the configured length of the controlled subject is the minimum set length, it means that the length of the controlled subject is the same as the length of each object, and the relative positions of the controlled subject and the objects can be set so that the controlled subject only touches one object in each row of objects in the group, thereby enabling the trainee to not only fit at least one object in each row of objects when performing the training task, but also to only touch one object in each row of objects when the length of the controlled subject is the minimum set length, rather than multiple objects, to leave more room for growth, and to encourage the trainee to continue to work hard to perform the training task so that the length of the controlled subject increases and touches more objects.

[0049] In some other embodiments of the present application, the processor 101 is further configured so that, at least during the training phase, on the display interface, the maximum set length of the controlled subject is greater than or equal to the distance between the objects on both sides of the group. Specifically, the trainee hopes to accommodate more objects or deform more objects by performing the training task. Therefore, the trainee expects that in the process of performing the training task, the controlled subject can be stretched to the maximum set length to accommodate more objects or deform more objects. Wherein, the maximum set length is greater than or equal to the distance between the objects in the leftmost column and the objects in the rightmost column of the group. At this time, when the maximum set length of the controlled subject is equal to the distance between the objects on both sides of the group, the controlled subject can accommodate the maximum number of objects or deform the maximum number of objects.

[0050] In some embodiments of the present application, when the object touched by the controlled subject is deformed, the processor 101 is further configured to present at least one row of objects that are away from the controlled subject, wherein the objects that touched the controlled subject are in a deformed state. Specifically, the object is dough and the controlled subject is a rolling pin. After the dough touches the rolling pin, the dough changes from a ball state to a dough sheet. For example, as the group of dough moves toward the rolling pin, the rolling pin elongates as the first blood oxygen concentration data increases while the trainee performs the training task, and the elongated rolling pin can touch each row of dough. When the rolling pin touches the first row of dough, the first row of dough changes into a dough sheet. The deformed dough sheet maintains the dough sheet state and continues to move away from the rolling pin. On the display interface, at least one row of dough sheets in a deformed state is presented. In this way, the trainees can see the dough turning into dough when it touches the rolling pin, which can increase the trainees' confidence in performing the training task and maintain a high level of interest, making the trainees more motivated to continue performing the training task.

[0051] In some embodiments of the present application, the processor 101 is further configured to update the cumulative value of the number of objects touched by the controlled subject, as displayed on the display interface, during the training phase. For example, as the number of objects touched by the controlled subject increases, the cumulative value increases accordingly. The doctor can understand the trainee's treatment status based on the statistical cumulative value, and the trainee will also gain confidence when seeing the continuous increase in the cumulative value.

[0052] In some embodiments of the present application, the processor 101 is further configured such that, if the trainee is a patient with limb movement disorders, when the first blood oxygen concentration data is equal to a first preset value, the length of the controlled subject is limited to the minimum set length. In this way, the controlled subject can at least touch one object in a row of objects, thereby preventing the trainee from losing confidence. In the case of a patient with attention deficit disorder, when the first blood oxygen concentration data is less than or equal to a second preset value, the length of the controlled subject is limited to the minimum set length. Even if the first blood oxygen concentration data is low when the trainee is performing a training task, the length of the controlled subject is maintained at the minimum set length and does not disappear. This helps the trainee maintain sufficient confidence to perform the training task. The first preset value and the second preset value are obtained based on the resting-state blood oxygen concentration data of the trainee when performing a resting-state task.
