Description

The motion frequency deriving means
Technical field
This utility model relates to field of computer technology, particularly a kind of motion frequency deriving means.
Background technology
Nervimotion is collaborative be human central nervous system, peripheral nervous system, autonomic nerve, with the autonomous synergistic function of motor system.Studies show that, the in various degree nerve centre functional lesion owing to the reasons such as disease, dysplasia, wound, neurosurgery cause such as cognitive dysfunction, will affect patient's nervimotion synergistic function.And the nervimotion synergistic function has and can cognitive competence, the learning capacity of object be concentrated such as energy, thinking speed, and the ability of reading and writing and so on exerts an influence.
Over nearly 10 years, neural Synergy and neural plastic theory are admitted widely, seek a kind of effective way cental system is carried out suitable intervention, we just can understand neuromotor function and the learning skill of object and the contact of other behaviors, psychology and spiritual problem, obstacle and so on of object, by appropriate training, we also can improve the neuromotor function of object and the learning skill of object.
And through studies show that, simple and accurate by finishing some, and task of needing maincenter just can carry out easily, may just can reflect or cognition, study or the behavior of description object on ability, thereby assessment neuromotor function, and by targetedly training, we think that the lifting of the ability of finishing these tasks also just means the lifting of neuromotor function.
At present for assessment of with equipment or the system of training neuromotor function, the ultimate principle of its training is, system sends the signal that instructs of audition or vision, measurand instructs the requirement of signal to finish corresponding action according to this, the user all can trigger a sensor in the moment of each execution, this sensor triggers the moment of determining user's execution by this, moment of whether instructing semaphore request to finish moment of finishing by this action is relatively judged the neuromotor function situation of current measurand, and namely prior art systems belongs to the nervus motorius harmony of judging measurand by phase demodulation.
In the prior art, when sensing user is moved, often only detect the moment that user action is finished, finish moment whether on system requirements deadline point or in the allowed band by this user action relatively, if, think that then the user has accurately finished corresponding action according to system requirements, otherwise that the user fails is fine according to the system requirements execution.There are two following defectives in it:
1, the accurate implementation of monitor user ' action of system is for example known the zero-time of its action executing etc.;
2, in the application process of said system, if measurand is carved the moment of having missed a requirement at a time, for example postpone execution in 5 seconds, an action must require to accelerate to finish just in 5 seconds and may catch up with the beat that instructs signal then, if and it is according to predetermined beat action, it can't finish in the moment of instructing semaphore request the action of next, and it is relatively poor or unbalance to be judged to neuromotor function, and above-mentioned acceleration can cause the neuromotor function of measurand further unbalance, cause actual needs to make system obtain the conclusion coordinating to finish by inharmonic action executing, therefore the detection accuracy of the system of prior art is not high, even violated the basic theories that nervimotion is coordinated: make measurand according to regular beat execution.

The specific embodiment
Describe this utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining this utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment 1:
The schematic flow sheet of a kind of motion frequency acquisition methods that Fig. 1 provides for the present embodiment.
Referring to shown in Figure 1, the motion frequency acquisition methods that the present embodiment provides mainly comprises following process step.
Step 101: detect in real time and obtain the acceleration signal of described user in course of action.
In user's execution action process, the sensor sensing user action implementation that can pass through obtains the triggering signal that is triggered by user action.
