It is emphasized that the embodiment of the present invention claimed be system shown in Figure 1 composition and its structure, when being based on The function of training stage is just enabled during above-mentioned composition structure.Additionally, by description above, the training stage substantially enters The accurate power of row finger strength pressing control test that is to say, that this system pass through strategy accordingly constantly carry out finger strength by The accurate power of pressure controls test adaptive adjustment difficulty of test.

When the accurate power of finger strength pressing each time controls test, in system, the handling process of signal is as shown in Figure 2.When So, Fig. 2 is only schematic diagram, and wherein vibrating motor and the quantity of pressure transducer is only for example, and is not construed as limiting.

The composition and its structure of system is described in detail above, below the process to the training stage and The accurate power of finger strength pressing controls the principle of test to do detailed introduction.

The accurate power that training stage relate to finger strength pressing controls test, in the embodiment of the present invention, the embodiment of the present invention In the accurate power of finger strength pressing control and contain initial constant in test and fix target force f₀, initial tolerance value w₀, maximum phase To tolerance δ_max, minimum relative tolerance value δ_min, maximum duty cycle η_max, minimum duty cycle η_min, tolerance w_j, relative tolerance value δ_j, dutycycle η_jReal-time force f with corresponding finger_i；Control two important ginsengs in test by the accurate power that finger strength is pressed Amount { δ_j,f_iCollaborative Control dynamically to adjust absolute tolerance value w_j, thus the accurate power of adjustment finger strength pressing each time controls The difficulty of test, the level of ability adaptively following user makes its task difficulty always close to the Limiting Level of user；Specifically As follows:

δ_jRelative tolerance value when refreshing for jth time tolerance, tolerance w when it is refreshed with jth time tolerance_jHave as follows Relational expression: w_j=f₀·δ_j.

And δ_jNumerical values recited be controlled by dutycycle η_j, its expression formula is as follows:

$\left\{\begin{array}{cc}{\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_j\&centerdot;(1-\mathrm{\&alpha;}),& {\mathrm{\&eta;}}_j>{\mathrm{\&eta;}}_{\max }\\ {\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_j,& {\mathrm{\&eta;}}_{\min }\&le;{\mathrm{\&eta;}}_j\&le;{\mathrm{\&eta;}}_{\max }\\ {\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_j\&centerdot;(1-\mathrm{\&alpha;}),& {\mathrm{\&eta;}}_j<{\mathrm{\&eta;}}_{\min }\\ {\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_{\max },& {\mathrm{\&delta;}}_{j+1}>{\mathrm{\&delta;}}_{\max }\\ {\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_{\min },& {\mathrm{\&delta;}}_{j+1}<{\mathrm{\&delta;}}_{\min }\end{array}\right.;$

In above formula, α is the coefficient less than 1.

Described dutycycle η_jIt is in the tired of target force range of tolerable variance for all voltage signals in each group voltage signal data Timing is long, accounts for the percentage ratio of total duration before training mission starts to refresh to jth time tolerance that is to say, that dutycycle η_j's Size, with each group of voltage signal data f_iRelated.

Due to fixing target force f₀, initial tolerance value w₀, maximum relative tolerance value δ_max, minimum relative tolerance value δ_min, maximum Dutycycle η_max, minimum duty cycle η_minBe default Fixed constant, thus its constant value exist infinite multiple.And real daily life In, when we execute accurate operation by finger fingertip, the power being applied is generally and little.In order to study conveniently, have chosen one Individual typical initial value, i.e. initial constant fixation target force f₀=2n, initial tolerance value w₀=0.2n, maximum relative tolerance value δ_max =0.5, minimum relative tolerance value δ_min=0.05, maximum duty cycle η_max=0.8, minimum duty cycle η_min=0.7.Require emphasis It is that hereinbefore the assignment of some constants by way of example only, is not construed as limiting；Can set according to demand in actual applications Determine or change its size value.

Based on the Computing Principle of above-mentioned dutycycle, the main control module in the embodiment of the present invention, it is additionally operable in training mission After end, in calculating each group voltage signal data, all voltage signals are in the accumulative duration of target force range of tolerable variance and account for this instruction The percentage ratio of total duration t practiced, and the achievement that the percentage ratio calculating is trained as this.

In training stage, the accurate power of finger strength pressing controls the schematic diagram of test as shown in Figure 3.The two of bottom in Fig. 3 Individual image illustrates the position of touch feedback, and this two schematic diagrams are all shown by the form that one or several vibrating motors vibrate Show.In example shown in Fig. 3,4 pressure transducers (precision is 0.1n) are provided with base 8, pressure transducer collects Accurate pressing force signal be finally transferred in host computer training information input module 1, the power of slave computer Logic control module 5 is touched Feel signals collecting frequency is 500hz.After the accurate power completing a finger strength pressing controls test, main control module can pass through Fingers carry on the back vibrating motor 6 and cervical region vibrating motor 7 exports the result feedback in tactile；For example, when single finger real-time force surpasses When crossing the range of tolerable variance upper limit, respective finger refers to back of the body vibrating motor 6 and can produce warning vibrational feedback；When all finger real-time force exist When in range of tolerable variance, cervical region vibrating motor 7 produces incentive massage type vibrational feedback.

It is emphasized that the embodiment of the present invention is not carried out to tolerance refreshing frequency k and real-time force value refreshing frequency Set and limit, the tolerance refreshing frequency k shown in Fig. 3 and real-time force value refreshing frequency are only for example and are not construed as limiting, specifically Data setting can be set according to practical situation by staff.

On the other hand, the said system that the embodiment of the present invention is provided, can also be divided into according to its information governance policies 4 parts as shown in Figure 4: central control system 9, haptic feedback system 10, adaptive control system 11 and execution system 12.

In fact, the detailed process of this 4 parts has been carried out detailed introduction above；Only briefly retouched herein State.

In adaptive control system 11, host computer training information input module 1 receives finger strength acquisition module 2 collection Finger strength input information.In haptic feedback system 10, the instruction sent according to slave computer Logic control module 5, control Fingers Back of the body vibrating motor 6 and the start and stop of cervical region vibrating motor 7.In adaptive control system 11, using line closed loop control as shown in Figure 5 Strategy use family processed remains near close to itself Limiting Level in the performance in once complete training process.Host computer The success or failure result of each power control task is sent to haptic feedback system 10 by training information input module 1, is carried on the back by Fingers Vibrating motor 6 and cervical region vibrating motor 7 output feedback result.

In conjunction with Fig. 3-Fig. 4, when the accurate power of finger strength pressing each time controls test, it is firstly received Fingers back of the body vibration Motor 6 or the vibratory stimulation of cervical region vibrating motor 7, thus induce the activity of the tactilely-perceptible cortex of brain 13, and by brain 13 Motor cortex control finger go execute pressing force transducer power control task.Active force tactile passage on finger is more simultaneously The activity of the secondary tactilely-perceptible cortex exciting brain 13.Every time during control task reaction, Fingers back of the body vibrating motor 6 and cervical region shake Dynamic motor 7 provides vibrotactile feedback, that is, inspire the connection activity of brain 13.Thereafter four fingers of right-hand man alternately make at random With, a finger activity, other fingers suppress, or refer to activity simultaneously more, and this process enhances left and right brain and frequently leads to callosal News.So that the attention of user is in the training process, continuously focus among the execution of task.

By the training of this continuous attention focusing activity, and training mission is automatically adjusted by adaptive algorithm Difficulty adapts to the control ability of user's continuous improvement or the individual variation of different people, and closed loop control algorithm makes user that training is appointed The input of the enthusiasm of business and attention all maintains a top level all the time.Strengthen the life of attention activity in brain 13 Reason function, thus reach the purpose of the attention improving target group.

In the training stage, by the way of line closed loop controls, adaptive real-time update absolute tolerance value w_jBig Little, thus adjusting task difficulty so that task difficulty is all the time close to the Limiting Level of user.

The scholar montani of Italian padova university proposes, and so that the success rate of user is maintained in video-game design When 75%, user participates in the subjective enthusiasm highest of game.

Therefore, in following example, dutycycle (i.e. success rate) can be set to 75% and nearby (that is, η is set_max= 80%, η_min=70%)；Certainly, above-mentioned concrete numerical value is only for example and is not construed as limiting.

The process that line closed loop controls is as shown in fig. 6, detailed process is as follows:

In shown main control module, absolute tolerance value w_j=f₀*δ_j, control relative tolerance value δ_jChange can control definitely Tolerance w_jChange.Relative tolerance value δ_jBy dutycycle η_jControl:

$\left\{\begin{array}{cc}{\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_j\&centerdot;(1-\mathrm{\&alpha;}),& {\mathrm{\&eta;}}_j>{\mathrm{\&eta;}}_{\max }\\ {\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_j,& {\mathrm{\&eta;}}_{\min }\&le;{\mathrm{\&eta;}}_j\&le;{\mathrm{\&eta;}}_{\max }\\ {\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_j\&centerdot;(1-\mathrm{\&alpha;}),& {\mathrm{\&eta;}}_j<{\mathrm{\&eta;}}_{\min }\\ {\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_{\max },& {\mathrm{\&delta;}}_{j+1}>{\mathrm{\&delta;}}_{\max }\\ {\mathrm{\&delta;}}_{j+1}={\mathrm{\&delta;}}_{\min },& {\mathrm{\&delta;}}_{j+1}<{\mathrm{\&delta;}}_{\min }\end{array}\right.$

Once include several times force value (i.e. the voltage signal data of some groups of Real-time Collections) in real time because tolerance refreshes Refreshing, and the refreshing frequency of real-time force value is stablized constant, therefore in this example, the time during dutycycle is defined is converted to The refreshing frequency of force value in real time.

Then dutycycle η_jIt is in the number of times s in target zone by finger real-time force_iImpact:

${\mathrm{\&eta;}}_j=\frac{\underset{i=0}{\overset{m}{\&sigma;}}{s}_i}{m};$

In above formula, m is the total degree that in the unit time, force value refreshes in real time.

Real-time force is in the number of times s in target zone_iBy real-time force value f_iWith relative tolerance value δ_jJoint determination:

When total duration t reaching this training, terminate training.

Additionally, the accurate power of the finger strength pressing of described training stage control test include for a finger test or The combined test of multiple fingers.For example, the quantity of pressure transducer can be set to 10, the quantity of vibrating motor It is set to 10；Meanwhile, the accurate power carrying out referring to collaborative finger strength pressing controls test more, and is respectively the offer of each finger not With vibratory stimulation and the feedback of form, such that it is able to further Development Finance and the more training mission of difficulty level.

Through the above description of the embodiments, those skilled in the art can be understood that above-described embodiment can To be realized by software it is also possible to realize in the way of by software plus necessary general hardware platform.Based on such understanding, The technical scheme of above-described embodiment can be embodied in the form of software product, this software product can be stored in one non-easily The property lost storage medium (can be cd-rom, u disk, portable hard drive etc.) in, including some instructions with so that a computer sets Standby (can be personal computer, server, or network equipment etc.) executes the method described in each embodiment of the present invention.
