Compared with the prior art, the embodiment of the application has the beneficial effects that:
the nerve feedback training device provided by the embodiment of the application provides interesting training tasks with rich feedback forms for trainees, in the training stage, the group containing regularly arranged objects is presented on the display interface to advance relative to the controlled main body, and the objects touching the controlled main body can be contained or deformed by the controlled main body. The training task is not only to make the controlled main body change, but also to make the trainee make more objects deform or be stored after making the controlled main body change through the training effort, and after the trainee directly observes that the object touching the controlled main body is stored or is deformed, the trainee can visually and intuitively feel the achievement of self-effort, for example, with the gradual accumulation of the object stored in the controlled main body, great satisfaction and achievement sense can be obtained, and the trainee wants to store more objects more in an effort manner, and the rich feedback form greatly improves the enthusiasm of the trainee to execute the training task. Of course, when the trainee sees that the object touching the controlled body is deformed, strong visual impact is generated, and the interest of the trainee in executing the training task is improved due to the deformation of the object. In this way, the trainee is advantageously kept high attentiveness during the training task. The feedback result in the application comprises the length change of the controlled main body, the contact of the controlled main body and the object and the deformation or the storage of the object, so that even if the length of the controlled main body is in negative change, the trainee can not lose the confidence and the training interest completely due to the contact of the controlled main body and the object and the deformation or the storage of the object, but can strive to self-adjust to achieve better training effect.

Meanwhile, as the controlled body is elongated, the more the number of objects received or deformed by touching the controlled body, the greater the feeling of achievement can be produced by the trainee. In the rest stage of the trainee executing the rest task, the display content on the display interface of the stage is distinguished from the display content of the training stage, the controlled subject which can stretch with the second blood oxygen concentration data is displayed on the display interface, but the group is not displayed, and the stretching state of the controlled subject stretches with the lifting of the second blood oxygen concentration data. In this way, the user (for example, doctor) can judge the training effect and the reality thereof by comparing the extension and contraction conditions of the controlled body in the rest stage and the training stage, for example, if the controlled body is not correspondingly shortened or even lengthened after the trainee enters the rest stage, the doctor can judge that the state of the nerve feedback training device or the trainee is problematic based on the conditions, and the display interface in the rest stage does not contain an object, so that the trainee cannot maintain a relaxed state due to the interference of the object when the trainee performs the rest task, and the training effect is influenced.

Fig. 1 (a) shows a schematic structural diagram of a nerve feedback training device according to an embodiment of the present application. The biofeedback training device 100 includes at least a processor 101 and a display 102, wherein the display 102 may be used to provide an interface corresponding to the training tasks and rest tasks performed by the trainee and the execution of other tasks performed. The processor 101 is configured to perform step S103-step S106 shown in fig. 1 (b). It should be noted that, the processor 101 may perform processing configuration not in the order of step S103 to step S106, and those skilled in the art may adjust the execution order of step S103 to step S106 according to the need.
In step S103, the trainee is prompted to execute an alternately performed training task and a rest task, in step S104, first blood oxygen concentration data of the trainee in a brain region related to a training phase and second blood oxygen concentration data of the trainee in a brain region related to a rest phase are obtained, the first blood oxygen concentration data is obtained based on near infrared data of the training phase acquired by a near infrared data acquisition module, and the second blood oxygen concentration data is obtained based on near infrared data of the rest phase acquired by the near infrared data acquisition module. Wherein the training task may be configured according to the type of illness of the trainee, for example, in case the trainee is a patient with limb movement disorder, the training task may be imagination of limb movements, such as imagination of left or right hand continuous grip; in the case that the trainee is a patient with attention deficit disorder, the training task may be that the focused imagination recipient subject changes, for example, the focused imagination controlled subject becomes longer, which is not particularly limited, and may be selected or self-configured by a doctor according to the type of illness of the trainee. For rest tasks, the trainee may be required to remain in a relaxed state, and other methods of performing rest tasks are not excluded.
The first blood oxygen concentration data and the second blood oxygen concentration data may be the relative change amounts of oxygenated hemoglobin, deoxygenated hemoglobin or total hemoglobin of the relevant brain region obtained by determining the near infrared data acquired by the external near infrared data acquisition device or the built-in near infrared data acquisition module, and preferably, the relative change amounts of oxygenated hemoglobin concentration are adopted. In the case that the trainee is a patient with limb dyskinesia, the relevant brain regions may be left and right motor brain regions of the trainee and/or S1 region primary trunk sensory cortex, the left and right motor brain regions at least include M1 region primary motor cortex; where the trainee is a patient with attention deficit disorder, the relevant brain region therein may be the frontal lobe of the trainee, preferably the dorsolateral frontal lobe of the trainee.
In this embodiment, the near infrared data acquisition module may be integrated into the neurofeedback training device 100, so as to acquire near infrared data of the trainee in a training stage and a rest stage, and after the near infrared data is acquired, analysis and processing are performed to obtain first blood oxygen concentration data and second blood oxygen concentration data, respectively.
In addition, the nerve feedback device 100 may further include an interface (not shown), and an external near infrared data acquisition device may be used in cooperation with the nerve feedback training device 100, where the nerve feedback training device 100 acquires the first blood oxygen concentration data and the second blood oxygen concentration data based on the interface. As shown in fig. 2, near infrared data of the relevant brain region may be acquired by a near infrared data acquisition device 202, the near infrared data acquisition device 202 having at least a headgear 201, the headgear 201 being for wearing over the head of a trainee. For example, the headgear 201 may have a plurality of probes for transmitting near infrared light and/or receiving near infrared light. Wherein each of the plurality of probes may be configured as either a transmitting probe (S) or a receiving probe (D), each pair of paired probes may form a probe channel. In some embodiments, one transmitting probe may correspond to multiple receiving probes, or vice versa, one receiving probe may correspond to multiple transmitting probes, the pairing of which depends on the specific requirements of the deployment location of the probes, the area of brain function to be detected, etc.
Near infrared data may be acquired for the relevant brain region while the trainee performs the training task, the rest task, by using the near infrared data acquisition device 202 or other devices used in conjunction therewith, thereby acquiring near infrared data while the trainee performs the training task and the rest task.
The interface may transmit information and may include, but is not limited to, a network adapter, cable connector, serial connector, USB connector, parallel connector, high speed data transmission adapter, etc., such as fiber optic, USB 3.0, thunderbolt interface (Thunderbolt), etc., a wireless network adapter, such as a WiFi adapter, a telecommunications (3G, 4G/LTE, etc.) adapter, etc. In some embodiments, the interface may be a network interface, through which the neuro-feedback training device 100 may connect to a network, such as, but not limited to, a local area network or the internet.
The biofeedback training device 100 in this embodiment may further include a speaker (not shown) through which a voice prompt prompting the trainee of the operation contents of the training task and the rest task that it performs is issued. In this way, the trainee can quickly become familiar with the task content through the voice prompt and the animation displayed on the display interface, and quickly enter the training state.
In step S105, in the training phase, a group including regularly arranged objects is presented on a display interface to travel relative to a controlled subject, and the objects touching the controlled subject are received or deformed by the telescopic controlled subject; the telescopic state of the controlled subject is presented in association based on the first blood oxygen concentration data. The controlled body can stretch according to the rising and falling of the first blood oxygen concentration data, for example, if the first blood oxygen concentration data rises along with the stimulation of the training task in the process of executing the training task by the trainee, the controlled body stretches along with the rising of the first blood oxygen concentration data; if the first blood oxygen concentration data decreases during the training task performed by the trainee, the controlled subject shortens as the first blood oxygen concentration data decreases. That is, the expansion and contraction state of the controlled subject is presented in association with the first blood oxygen concentration data, so that the change condition of the first blood oxygen concentration data of the trainee when the trainee performs the training task can be intuitively reflected.
By utilizing the technical scheme of the application, a timely, visual and clear linkage action mechanism of training performance of the trainee relative to a controlled main body can be provided for the trainee, and in short, the controlled main body executes the elongation action after the training performance is good; and, more objects are touched to the controlled body to be received or deformed. Thus, feedback elements with proper regularity of the controlled subject-object group are introduced through the display interface, and real-time dynamic feedback (training performance is good-controlled subject elongation) and accumulated dynamic feedback (more objects are stored or deformed) are provided for the trainee in a combined mode, so that feedback information is more comprehensive and richer. Moreover, controlled subject elongation-a scene in which more objects are stored or deformed-is easily associated with realistic familiar scenes for trainees of various cognitive levels (such as rolling skins for children, storage stones for elderly people, described in detail below), not only is it easy to understand, but skillfully hits points of interest specific to children-elderly people, children like to get mastery and achievement (such as sand play, plasticization) by deforming objects, elderly people like to get mastery and achievement (such as hoarding old objects, tableware, etc.) by stocking or storing objects, these two types of behaviors are intended and considered to be done with confidence by themselves, and young and middle-aged individuals between children and elderly people are also generally interested in object deformation and storage strongly. The application provides a training task and feedback information rich in fun and feeling, so that a trainee can quickly enter a training state, and even if the length of a controlled body is shortened, the trainee can not completely lose confidence and training interest due to the contact of the controlled body and the object and the deformation of the object or the received feedback result, but can struggle to perform self-adjustment to achieve better training effect and keep higher attention, power and confidence to finish.
On the display interface of the display 102, a group containing regularly arranged objects is also presented, the group being animated to travel relative to the controlled subject. Wherein the object and the controlled subject may be configured according to the type of animation, for example, the animation may be a mine car for precious stone, and the controlled subject may be a mine car; the animation may be a rolling skin, the object may be a dough, and the controlled body may be a rolling pin; the animation can be picking apples, the object can be apples, the controlled body can be a fruit basket and the like, and the specific types of the object and the controlled body are not limited, so long as the animation is matched with the training task based on the matching of the object and the controlled body.
The controlled body is described as a mine car by taking the object as a gemstone as an example, but the present application is not limited thereto.
On the display screen of the display 102, a regularly arranged gemstone array made up of gemstone of different colors is presented, with the row spacing between rows of the gemstone array being within a threshold row spacing range and the column spacing between columns being within a threshold column spacing range, so that the spacing between the rows, columns, of the gemstone array is not too narrow or too wide. Specifically, the mine car is configured below the precious stone array, the precious stone array falls down towards the direction of the mine car, wherein the downward advancing speed of the precious stone array does not exceed the threshold advancing speed, so that the mine car cannot be accommodated in more precious stones due to the fact that the falling speed of the precious stone array is too high and the mine car is not stretched, and the self-confidence of a trainee is reduced. Or, due to too slow falling speed of the gemstone array, the mine car cannot be stored in time, and the trainee can lose training self-confidence. Thus, on the display interface, the speed at which the group travels toward the controlled subject does not exceed the threshold travel speed range, enabling effective maintenance of self-confidence in the trainee's performance of the training task.
Along with the rising of the first blood oxygen concentration data, the mine car stretches, meanwhile, the precious stone array moves towards the mine car, and precious stones touching the mine car are stored in the mine car. Of course, as the mine car stretches, the entrance of the mine car increases, and the number of gemstones received by the mine car at the same time increases. The trainee can see that the stored precious stones are accumulated in the mine car, so that a larger achievement sense and a satisfaction sense can be obtained, and the trainee can keep higher self-confidence and attention to continuously complete the training task.
In another embodiment, where the object is a dough and the controlled body is a rolling pin, the rolling pin is moved by a regularly arranged array of dough, and during the fall of the array of dough, the dough hits the rolling pin and the dough becomes flat and deformed. As the first blood oxygen level data increases, the rolling pin elongates, and in the event of elongation of the rolling pin, the amount of dough that is touched and deformed by the rolling pin increases. During the training task execution process, the trainee deforms the dough through effort, so that the interest of executing the training task is increased, and the confidence and achievement feeling of the trainee are improved.
In some embodiments, the position of the controlled subject is unchanged, the group comprising regularly arranged objects is a preset distance from the controlled subject at the beginning of the training phase, and the group travels towards the controlled subject. In this embodiment, the controlled subject is not in contact with the subject at the beginning of training, but rather has a predetermined distance from the controlled subject, because the first blood oxygen concentration data of the trainee has a certain rise period compared with other physiological data such as an electroencephalogram signal, and the first blood oxygen concentration data can generally reach a higher value after a period of time after the trainee begins to perform a training task, so that the group including regularly arranged subjects is spaced from the controlled subject by the predetermined distance at the beginning of the training period in the present application, so as to prevent the controlled subject from being unable to contact more subjects due to the slow rise of the first blood oxygen concentration data, thereby reducing the training confidence of the trainee.
In step S106, during a rest phase, the controlled subject is presented in a telescopic manner on a display interface without presenting the group of regularly arranged objects, and the telescopic state of the controlled subject is presented in association based on the second blood oxygen concentration data. That is, on the display interface of the display 102, the group containing the regularly arranged objects is no longer displayed, but only the telescopic controlled subject is displayed. For example, in the training phase of the training task, the object is a gemstone, the controlled body is a mine car, the gemstone array travels in the direction of the mine car during the training task performed by the trainee, and the gemstone is received by the mine car after touching the mine car. After the training task is finished, the user enters a resting stage of the resting task, and at the moment, the precious stone array on the display interface disappears and only the telescopic mine car is displayed.
After the trainee enters the rest stage, the second blood oxygen concentration data of the relevant brain area is reduced, at this time, the acquired second blood oxygen concentration data is reduced, and correspondingly the controlled body is shortened, namely the telescopic state of the controlled body is presented in a correlated manner based on the second blood oxygen concentration data. On the display interface of the rest stage, only the controlled main body is presented, but not the group of the regularly arranged objects is presented, and the trainee can only see the controlled main body on the display interface without the interference of other objects, so that the rest stage can better keep a relaxation state, and further, the training task can not be continuously executed.
The doctor can judge the current physiological condition of the trainee by observing the change condition of the controlled body on the display interface in the rest stage, and judge the training effect and the authenticity of the training effect by the length change of the controlled body in the training stage and the rest stage. For example, if the trainee enters the rest period to perform the rest task after the training task is finished, the second blood oxygen concentration data will decrease with the end of the training task and the start of the rest task, and accordingly, the controlled main body will shrink from the original length to become shorter. However, if the controlled subject does not shorten or even lengthen after the trainee enters the rest phase, the physician may determine based thereon that there may be a problem with the biofeedback training device 100 or the trainee's current physiological condition, requiring a manual review of the biofeedback training device 100, or further analysis of the trainee's current physiological condition. Alternatively, this may be the case because the first blood oxygen concentration data of the trainee at the time of performing the training task is already relatively low, the second blood oxygen concentration data is not lowered, or the second blood oxygen concentration data is slightly different from the first blood oxygen concentration data, at which time the training effect of the trainee may be considered to be relatively poor.
Therefore, as the object touches the controlled body and is contained or deformed by the controlled body, the trainee can intuitively see the accumulation or deformation of the number of the object in the controlled body. The visual picture can enable the trainee to obtain larger achievement sense and satisfaction sense, and can keep higher self-confidence of executing training tasks. Moreover, the trainee performs the training task and the rest task which are alternately performed, and when the rest task is performed, the doctor can evaluate the current physiological condition of the trainee or judge whether the neuro feedback training device 100 fails or not according to the telescopic state of the controlled body of the trainee when the rest task is performed, so that the doctor can adjust the training task in time or check the neuro feedback training device 100.
In some embodiments of the application, the processor 101 is further configured to present the controlled subject on a display interface with a center that is offset from a center of the group of objects by less than half the distance between adjacent objects; the controlled body changes its telescopic state in such a manner as to be simultaneously telescopic to both sides. Specifically, as an example of the animation of the mine car seeking a gemstone, as shown in FIG. 3, a set 303 of gemstones 302 is presented on the display interface 301, the set 303 traveling toward the mine car 304. The mine car 304 stretches as the trainee's first blood oxygen concentration data rises while performing the training task, and as the mine car 304 stretches, the entrance of the mine car 304 becomes wider, more of the precious stones 302 are more easily received. As the set 303 drops downwardly, the gemstone 302 touching the mine car 304 is received. In this embodiment, the controlled body changes its telescoping state in a manner that it is simultaneously telescoping to both sides, such as the mine car 304 of FIG. 3, which may be centered about the centerline a of the mine car 304, holding the center stationary, telescoping the mine car 304 from the center to both sides. If the center line a of the mine car 304 coincides with the center line b of the group 303, the mine car 304 is simultaneously telescopic to two sides, so that the condition that any row of precious stones 302 cannot be touched is likely to occur under the condition that the length of the mine car 304 is small, and the trainee feels effort but does not obtain frustration of the precious stones 302, and thus loses confidence of performing training tasks. For this purpose, the centre line a of the mine car 304 is arranged offset from the centre line b of the group 303, i.e. the centre line a of the mine car 304 and the centre line b of the group 303 do not coincide. In addition, the offset distance between the center line a of the mine car 304 and the center line b of the group 303 is smaller than half of the distance between two adjacent gemstones 302, so that one side of the mine car 304 can be ensured to be contacted with the gemstones 302 firstly in the process of advancing towards the mine car 304, the training task is performed by a trainee, the training task can be performed by the trainee by slightly struggling with the gemstones 302 in at least one row, and the self-confidence of the training task performed by the trainee can be effectively maintained.
In some embodiments of the present application, the processor 101 is further configured to present, prior to the training phase, an exercise animation conforming to the operation content of the exercise task performed by the trainee on the display interface, so that the trainee performs the exercise task based on the exercise animation. The trainee can activate the relevant brain area by executing the training task, so that the relevant brain area of the trainee executes the training task after being activated, and a better treatment effect can be obtained.
For example, before performing an exercise task, the trainee may be required to perform a resting state task, during which the trainee remains relaxed, resting state near infrared data of the relevant brain region of the trainee is collected using the near infrared data collection module, and resting state blood oxygen concentration data is obtained based on the resting state near infrared data. In this process, the resting state blood oxygen concentration data representative value may be determined based on an average value of resting state blood oxygen concentration data of a preset period of time during which the trainee performs the resting state task.
After the rest state task is executed, starting to execute the exercise task based on the exercise animation presented on the display interface, acquiring near infrared data of the activated relevant brain region of the trainee by utilizing the near infrared data acquisition module, and obtaining third blood oxygen concentration data based on the near infrared data. In the first area of the training task display interface, the group of regularly arranged objects moves relative to a controlled body, the controlled body dynamically stretches and contracts in a preset stretching range without being related to the third blood oxygen concentration data of the training task of the trainee, and the controlled body in the current stretching state touches the object to store or deform the touched object. In a specific embodiment, as shown in fig. 4, an animation that the group 403 including the object 402 travels toward the mine car 404 is displayed on the first area M on the display interface 401 of the trainee performing the training task, where the group 403 still travels toward the mine car 404 during the training task, however, the expansion and contraction of the mine car 404 is not related to the third blood oxygen concentration data, and is not related to the third blood oxygen concentration data, but is a preset animation effect, so that the trainee knows in advance that the mine car 404 will exhibit expansion and contraction change during the training process, and the expansion and contraction of the mine car 404 corresponds to the number of the objects 402 that can touch, so that the setting is due to inconsistent illness state of the trainee, if the expansion and contraction of the mine car 404 is related to the third blood oxygen concentration data during the training task, if the length of the mine car 404 does not change greatly, the trainee cannot clearly perceive the feedback result of the training effort or the training effort, for example, if the length of the mine car 404 is seriously elongated or the length of the trainee causes the elongation or the training effort, and the training effort is not reduced, and the training effect may not be very good, and the training result is not suitable for the trainee. The mine car 404 dynamically telescopes in a predetermined telescoping range that may be set by default by the neuro-feedback training device 100 or by the physician. In this manner, the trainee is allowed to perform the exercise task and is able to intuitively see that the group 403 is traveling toward the mine car 404 and that the object 402 touching the mine car 404 is received or deformed.
In a preferred embodiment, in this process, the third blood oxygen concentration data representative value may be determined (or directly used) based on an average value of the third blood oxygen concentration data for a preset period of time during which the trainee performs the exercise task. And comparing the acquired third blood oxygen concentration data representative value with the resting state blood oxygen concentration data representative value, and when the deviation of the third blood oxygen concentration data representative value relative to the resting state blood oxygen concentration data representative value exceeds a threshold value, considering that the activation degree of the relevant brain area of the trainee is higher, and preparing to enter a training stage of a training task.
In still other embodiments of the present application, where the trainee is a patient with limb dyskinesia, the processor 101 is further configured to present a limb animation guiding the trainee in the second area of the display interface of the exercise task, and the change in motion of the limb animation corresponds to the change in extension and contraction of the controlled subject. As shown in fig. 4, in the second region N, a limb animation is presented that guides the trainee in practice, the limb animation being a grasping movement of the hand, with the action of grasping the hand, the mine car 404 extending, with the action of opening the hand, the mine car 404 shortening, so that the action change of the limb animation corresponds to the telescopic change of the mine car 404. In this way, the trainee can be intuitively presented with the association between the gripping movement of the hand and the telescoping of the controlled body to encourage the trainee to focus on thinking like the gripping movement of the hand, in hopes of being able to receive more objects 402 through effort. In another embodiment, in the case where the trainee is an attention deficit disorder patient, an animation guiding the trainee's exercise may not be presented on the display interface 401 of the trainee performing the exercise task.
In other embodiments of the present application, the controlled subject moves left and right within a predetermined range during the process of performing the telescopic change, and the controlled subject still satisfies the position requirement that the center of the controlled subject deviates from the center of the group including the objects by a distance less than half of the distance between the adjacent two objects on the display interface of the trainee performing the training task or the exercise task during the movement. Therefore, the interest of the training task and the training task can be further improved, and the interest and the attention of the trainee for executing the training task are further improved.
In further embodiments of the present application, the processor 101 is further configured such that, at least during the training phase, a minimum set length of the controlled subject is greater than or equal to a length of a single object in a group on the display interface, and the controlled subject is capable of touching at least one object in each row of objects in the group. For example, taking the subject as a dough, the controlled body is a rolling pin, and the minimum set length of the rolling pin is not less than the length of one dough, so that the minimum set length of the rolling pin is equal to the length of the dough during the process of advancing the group of dough towards the rolling pin, and the controlled body can at least touch at least one dough in each row of dough through the setting of the relative positions of the controlled body and the subject, thereby enabling the trainee to maintain enough self-confidence to perform the training task.
In further embodiments of the present application, the processor 101 is further configured, at least during the training phase, on the display interface, for the controlled subject to touch only one object of each row of objects in the group when the controlled subject is of the minimum set length. That is, when the length of the controlled body is the minimum set length, it is stated that the length of the controlled body is the same as the length of each object, and the controlled body can touch only one object in each row of objects in the group through the setting of the relative positions of the controlled body and the objects, so that the trainee can not only receive at least one object in each row of objects when performing the training task, but also touch only one object in each row of objects instead of a plurality of objects when the length of the controlled body is the minimum set length to reserve more growing space, and the trainee can continuously struggle to perform the training task to make the length side of the controlled body touch more objects.
In still other embodiments of the present application, the processor 101 is further configured such that at least during the training phase, a maximum set length of the controlled subject is greater than or equal to a distance between the objects on both sides of the group on the display interface. Specifically, the trainee desires to receive or deform more objects by performing the training task, and thus, the trainee desires to receive or deform more objects by elongating the controlled body to a maximum set length during the performance of the training task. Wherein the maximum set length is greater than or equal to the distance between the left-most and right-most objects of the group, and at this time, the controlled subject may receive or deform the maximum number of objects if the maximum set length of the controlled subject is equal to the distance between the objects on both sides of the group.
In some embodiments of the present application, in the event that the object touched by the controlled object is deformed, the processor 101 is further configured to present at least one row of objects leaving the controlled object, and wherein the object touched by the controlled object presents a deformed state. Specifically, the subject is dough and the controlled body is a rolling pin. After the dough touches the rolling pin, the dough changes from a agglomerated state to a skin state. For example, as the dough set travels toward the rolling pin, the rolling pin may stretch as the trainee performs the training task as the first blood oxygen level data increases, and the stretched rolling pin may touch the dough of each row. When the rolling pin touches the dough of the first row, the dough of the first row is deformed into the dough cover, and the changed dough cover keeps the dough cover state and keeps moving away from the rolling pin. At least one line of dough sheets in a deformed state is presented on a display interface. Therefore, the trainee can see that the dough becomes the dough cover when touching the rolling pin, the confidence of the trainee in executing the training task can be improved, and a high degree of interest can be kept, so that the trainee is more motivated to continue executing the training task.
In some embodiments of the application, the processor 101 is further configured to update the cumulative value of the number of objects touched by the controlled subject displayed on the display interface during the training phase accordingly. For example, as the number of subjects contacted by the subject increases, the cumulative value increases, and the physician can learn about the treatment of the trainee based on the statistical cumulative value, and the trainee can see the increasing cumulative value, which can also enhance the confidence.
In some embodiments of the present application, the processor 101 is further configured to, in the case where the trainee is a limb dyskinesia patient, limit the length of the controlled subject to the minimum set length when the first blood oxygen concentration data is equal to a first preset value, so that the controlled subject can touch at least one of a row of objects, thereby avoiding the trainee losing confidence. In the case that the trainee is 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 body is defined as the minimum set length, and even if the trainee performs a training task, the first blood oxygen concentration data is low, the length of the controlled body is kept at the minimum set length and cannot disappear, so that the trainee is facilitated to maintain sufficient self-confidence to perform the training task. The first preset value and the second preset value are obtained based on resting state blood oxygen concentration data of the trainee when the trainee executes a resting state task.
