The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the present invention in detail, in this illustrative examples of the present invention and explanation, be used for explaining the present invention, but not as a limitation of the invention.
Embodiment 1:
The schematic flow sheet of the monitoring method of a kind of motor reaction situation that Fig. 1 provides for the present embodiment.
Shown in Figure 1, the monitoring method of the motor reaction situation that the present embodiment provides, mainly comprises following process step.
Step 101: output reference signal, requires to perform an action according to its frequency according to this reference signal with indicating user.
The frequency output of this reference signal to be scheduled to, forms a regular signal, and user can, according to the indication of reference signal, perform an action respectively according to the requirement of the frequency of reference signal.
In the present embodiment, reference signal can be, but not limited to export user to acoustical signal, picture signal etc.
The inventor, in research further investigation of the present invention, find, the reference signal preferred, users of the present embodiment can tactilely-perceptible signal, for example vibration signal, temperature signal, micro-current signal or other etc., this reference signal can pass to user by sending the vibration signal of preset frequency, and user carries out the action needing as indicated by this index signal of tactilely-perceptible.
Through the inventor's further investigation, find that sense of touch is the sensory organ of the human body bottom, also be the sensory organ that sensitivity is the highest, therefore can make user perceive this index signal from sense of touch by perceptual signal by sense of touch in the present invention, the motor reaction situation that can further reflect user, meets nervimotion theory more.
As further improvement, this reference signal can also can perceptual signal with sense of touch, such as vibration signal exports to user jointly in conjunction with sound or picture signal, to offer user, indicates widely.
This reference signal indicating user requires user: according to the frequency identical with reference signal, carry out specific action.These actions can be, but not limited to for: both hands are clapped one's hands, and certain palm is clicked certain position of health, walk, foot-operated floor or backing plate, left hand is clapped right arm, the right hand is clapped left arm, above any.
As the present embodiment a kind of preferably, the inventor finds in carrying out research process of the present invention, in the present embodiment, the frequency of reference signal can also be by being preset to equipment input by input terminal according to the practical situation of self by user, and equipment is according to the predefined frequency output reference of user signal in the present embodiment.The user of this predeterminated frequency can be also coach or other directors etc. for user oneself.
In addition, preferred as the another kind of the present embodiment, the frequency of reference signal can also be set according to the motion conditions of measurand is intelligent automatically by system in the present embodiment.Specific as follows:
In application, the triggering signal of the user action of system acquisition specific quantity (for example 5 times, 10 times or other arbitrary quantity), then calculate respectively the triggered time interval of the triggering signal that any two priorities are adjacent, for example: have five triggering signal S1, S2, S3, S4, S5 in turn, calculate S2-S2, S2-S3, S3-S4, triggered time interval between S4-S5, obtains respectively four interval T1, T2, T3, T4, computation time interval T 1, T2, T3, T4 meansigma methods T0.Then the frequency using the inverse of this meansigma methods as reference signal, output reference signal.
Because system in the present embodiment can also be according to the physical training condition of user's reality, intelligent induction user's motor reaction practical situation, according to this practical situation, with the adaptive frequency of user, output reference signal, instructs active user's action executing frequency.Make the more flexible use comfort with improving user of operation of system.
It should be noted that, the setting of the frequency of reference signal in the present embodiment can be set by the user, also can in training process, by action executing in advance, allow system intelligent induction determine the frequency that meets oneself by user, user can convert rhythm and pace of moving things rhythm according to present case like this, can also require and the quickening of own level threshold limit value or the task rhythm and pace of moving things reference signal that slows down according to trainer.
Step 102: Real-time Obtaining user moves respectively according to the frequency of reference signal the triggering signal triggering.
At output indicating user, carry out as requested after the reference signal of corresponding actions, user, according to this reference signal, performs an action according to the requirement of this reference signal.
User, hold in type course of action, the sensor sensing user action implementation that can pass through, obtains the triggering signal being triggered by user action.
This sensor can be infrared sensor in the present embodiment, or acceleration transducer, or high accuracy 3-axis acceleration sensor or other.
Adopt 3-axis acceleration the sensing accurately amplitude, rhythm, orientation, direction etc. of identification maneuver, can be at the acceleration of three-dimensional any one orientation determination user action.
The inventor finds in carrying out research process of the present invention, in the present embodiment, can choose acceleration transducer as the sensor of induction user movement direction and motor process situation.The inventor finds to obtain reflecting user's course of action by following technical scheme more accurately, comprehensively, and concrete technical scheme is as follows:
This acceleration transducer can be bundled in it user, for example on hand, waist is first-class, the acceleration signal performing an action in process by acceleration transducer Real-time Obtaining user, and these acceleration signals are passed to a triggering signal analytic unit, by this triggering signal analytic unit according to user in course of action the acceleration signal of (each time point), calculative determination is acceleration rate over time in course of action, degree of will speed up over time rate signal as triggering signal.
For example: after acceleration transducer obtains the acceleration signal of each time point in user action process, by these acceleration signals are analyzed, determine acceleration real-time change rate signal in time in course of action.Take claps one's hands moves as example, and when action launching, this acceleration starts to become large by zero, and hits in a flash clapping the hands, and this acceleration generation instantaneous variation, produces a backward acceleration.On the curve of rate of acceleration change and time, hit that rate of acceleration change is very precipitous in a flash clapping the hands, therefore according to action feature, the very precipitous part of this variation is for to have moved moment on determination of acceleration temporal evolution rate curve.
Moved after moment detecting at every turn, to host computer, sent id signal, in described id signal, comprised identifier, identifier is current is zero-time or the moment of completing of described action.Host computer receive sign action complete the id signal of moment time, record this time T of receiving 1, receive next sign action complete the id signal of moment time, record this time T of receiving 2, then the time interval T 0 of time T 1 to T2 being completed as user action, and 1/T0 is the frequency of triggering signal.
System can accurately must determine that zero-time or action that user action is carried out complete moment, or zero-time and action complete moment, and zero-time by any priority two triggering signals or action complete moment and can determine the cycle of triggering signal, thereby obtain accurately, comprehensive user action information.
Step 103: frequency discrimination comparison.
After obtaining the triggering signal that user performs an action at every turn, all carry out this step, the frequency of this triggering signal and reference signal size relatively, can determine that by this frequency ratio user moves the deadline at every turn and whether meets respectively reference signal frequency and want seeking time, and difference.
Step 104: according to frequency discrimination comparative result, determine user movement response situation.
According to the frequency discrimination comparative result of step 103, can determine respectively the difference that action deadline that user is each and reference signal frequency are wanted seeking time, thereby determine the current movement response situation of user.
In addition, in order to make conclusion more accurate, in the present embodiment, can also be by user being determined to the triggering signal of a series of actions and the comparative result of reference signal frequency of duration, these results are comprehensively analyzed, finally determined user's motor reaction situation.
In the present embodiment specifically according to frequency discrimination result, determine that user's motor reaction situation can determine according to the theoretical and relevant analysis software of nervus motorius of the prior art.The calculating that for example system can present frequency discrimination result carry out accurately quantizing with the form of statistics, these statistics comprise deviation range, bias direction and the distribution of frequency, the number of times of resonance, resonance continue (continuous resonance 4 times) number of times, lose the number of times of hardwood, ratio of off resonance etc.
Therefore, in the present embodiment, due in determining user's movement response situation process, frequency by the triggering signal that relatively user action triggers is compared with the frequency that is used to indicate the reference signal that user performs an action, can accurately determine the difference of deadline and the deadline that reference signal frequency requires of the each action of user, suppose that user departs from reference signal frequency in the deadline of certain action and wants after seeking time (inverse of frequency), when moving, next only need to want seeking time accurately to complete next action according to reference signal frequency, completing of next action will be considered to meet system requirements, and without the mistake due to a upper action, and carry out this mistake of velocity adaptive in this action.Therefore adopt the present embodiment technical scheme, by each, move the comparison of frequency and reference signal frequency of corresponding triggering signal, the motor reaction situation of judging user according to this frequency comparative result tallies with the actual situation more, more meets the principle of nervus motorius Coordination Theory.
In addition, in the present embodiment, after the triggering signal that obtains each action of user and the frequency discrimination that obtains each triggering signal and reference signal relatively after, also respectively the information of each triggering signal and each frequency discrimination comparative result are stored in system, so that system is done further utilization and analysis according to storage data: for example: statistical analysis, or make user's motor reaction situation curve, set up the individual database of user; System can also, according to the variation of user use curve, be carried out overall assessment and formulate further training plan or strategy the state of user.

In this step, system can be exported a feedback signal to user, this feedback signal can be sound or picture signal or haptic signal or above-mentioned arbitrary several combination, by this feedback signal, inform the frequency discrimination comparative result that user is current, thereby offer user guided, so that user completes next action better according to this feedback signal, make next action can meet better the frequency requirement of reference signal.
This frequency discrimination comparative result is generally divided into following three kinds:
1,, when the absolute value of the time difference Δ of current triggering signal and reference signal is equal to or less than 60ms, think that the current motion rhythm and pace of moving things coordinates;
2, when the inverse of frequency of current triggering signal and the difference reciprocal of the frequency of reference signal are for just, and difference DELTA is while being greater than 60ms, thinks that current motion is slower than reference signal;
3, when the inverse of frequency of current triggering signal and the difference reciprocal of the frequency of reference signal are negative, and the absolute value of difference DELTA is while being greater than 60ms, thinks that current motion is faster than reference signal.
Also can be further subdivided into very leading, leading, delay, delay very much, accurately and leakage hit six ranks.
