Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the application is made the most in detail Explanation.Following example are used for illustrating the application, but are not limited to scope of the present application.

It will be appreciated by those skilled in the art that in embodiments herein, the sequence number of following each step Size be not meant to the priority of execution sequence, the execution sequence of each step should with its function and Internal logic determine, and the implementation process of the embodiment of the present application should not constituted any restriction.

Inventor finds in research process, if held at the last position of health (such as arm) Row one presses, and this pressing can cause the blood flow burst at neighbouring position to spring up, and then make to collect Blood flow information changes.Further, if set gradually two biographies in the side being pressed position Sensor, at different time points, these two sensors can detect that the burst of this blood flow springs up.Enter One step, if changing the relative position of pressing position and detection position, then these two sensors Detect that the time relationship (such as sequencing) that the burst of this blood flow springs up may change.Base In this, then can identify, according to the blood flow information that these two sensors obtain, the position being pressed, And then may determine that the input information that the position being pressed accordingly is corresponding.Wherein, described blood flow letter Breath can be PPG (photoplethysmography, photoplethysmographic) information, or Person can also is that Doppler measurement information, such as LDF (Laser Doppler Flowmetry, Laser-Doppler flow velocity) information.

Fig. 1 is to input information described in one embodiment of the application to determine the flow chart of method, described Method can determine realization on equipment in such as one input information.As it is shown in figure 1, described method Including:

S120: be pressed in response to a position on health, at least two at described health detects Position obtains a blood flow information respectively, obtains at least two blood flow information；

S140: determine an input information according at least to described at least two blood flow information.

Method described in the embodiment of the present application, is pressed in response to a position on health, at described body At least two detection position of body obtains a blood flow information respectively, obtains at least two blood flow information, Then an input information is determined according at least to described at least two blood flow information.Thus provide one Plant the method that blood flow information based at least two detection position determines input information, described method Improve the input capability of the electronic equipments such as Wearable.

Below with reference to detailed description of the invention, describe the merit of described step S120 and S140 in detail Energy.

S120: be pressed in response to a position on health, at least two at described health detects Position obtains a blood flow information respectively, obtains at least two blood flow information.

Wherein, described health can be the health of people or animal, simple for the sake of, the application is many Illustrate as a example by the health of people.

Described position and described at least two detection position can be appointing on described user's body Meaning position, it is contemplated that user operation is convenient, and blood flow information is pressed, and impact is obvious to be risen See, described in the position that is pressed and described at least two detection position preferably same at described health On one limbs, such as can be respectively positioned on the arm of a user.

Described blood flow information can be such as PPG information or Doppler measurement information, and it can To be obtained by corresponding sensor acquisition, such as can be obtained by PPG sensor acquisition Described PPG information.

In one embodiment, this step S140 may include that

S141: according at least to described at least two blood flow information determine described in the position that is pressed；

The described input information that S142: the position that is pressed described in determining is corresponding

As it was noted above, in described step S141, described blood flow information can be such as PPG Information or Doppler measurement information, will be below PPG information or many to described blood flow information Illustrate respectively in the case of general Le metrical information.

A), in one embodiment, described blood flow information is PPG information, described accordingly Step S141 is further:

S141a: according at least to described at least two PPG information determine described in the position that is pressed.

Fig. 2 is the waveform diagram of the PPG information collected under normal circumstances, and it presents bright Aobvious cyclically-varying, can reflect the health indicator such as heart rate of collected object.Fig. 3 be The waveform diagram of the PPG information collected when being pressed near detection position, wherein oval Interior waveform correspondence push action, it can be seen that this portion waveshape occurs in that obvious range value Declining, this is to increase suddenly owing to push action causes detecting the blood volume near position.

Wherein it is possible to by the local of this for the waveform in ellipse in similar Fig. 3 corresponding push action Waveform is denoted as target waveform.The most in one embodiment, can be by comparing the side of range value Formula determines described target waveform, and range value is such as less than the valley value of normal PPG waveform Waveform recognition is described target waveform.

It addition, in some cases, if the push action correspondence moment is just at normal PPG Waveform should occur the moment of crest, then may causing described target waveform such as the ellipse in Fig. 4 Waveform in region.In this case, although push action also causes the amplitude of PPG waveform Range value after value substantially reduces, but it reduces still is not less than normal PPG waveform Valley value.Therefore, in another embodiment, the PPG information that detection can be obtained It is divided into many sub-PPG information by the cycle；Then, by the plurality of sub-PPG information respectively Do cross-correlation calculation with one with reference to PPG information, identify described object wave according to result of calculation Shape.

Still as a example by waveform shown in Fig. 4, can be according between adjacent trough being a cycle, will Shown in Fig. 4, waveform is divided into C1, C2, C3, C4, C5, altogether 5 sub-waveform, and these are 5 years old Corresponding 5 the sub-PPG information of individual sub-waveform.Wherein, the waveform of marginal portion can be ignored, This is because when gathering described PPG information, excess some PPG information can be gathered.

Described can be between two troughs collected under normal circumstances with reference to PPG information PPG waveform, is carried out with above-mentioned 5 sub-PPG information with reference to PPG information respectively by described mutually After correlation computations, it is found that the described cross-correlation calculation result with reference to PPG information with C3 It is significantly less than the described cross-correlation calculation result with reference to PPG information with other sub-PPG information, May determine that sub-PPG information corresponding for C3 is described target waveform accordingly.

In actual application, can be by described mutual with reference to PPG information and each sub-PPG information Correlation calculation result and a threshold value compare, if less than this threshold value, then it is assumed that corresponding Sub-PPG information is target waveform.Described threshold value can such as be set to described with reference to PPG letter Breath and the 80% of the cross-correlation calculation result of self.

It will be appreciated by those skilled in the art that above two determines that the mode of described target waveform is all right It is applied in combination, to improve accuracy and efficiency.

In one embodiment, described at least two PPG information is just two PPG letters Breath, described step S141a may include that

S141a ': a PPG information corresponding according to the first detection position and the second detection position The 2nd corresponding PPG information determine described in the position that is pressed.

In one embodiment, described step S141a ' can be further:

S1411a ': determine one first spy that described pressing is corresponding in a described PPG information Levy a little；

S1412a ': determine one second spy that described pressing is corresponding in described 2nd PPG information Levy a little；

S1413a ': the very first time corresponding according to described fisrt feature point and described second feature The second time that point is corresponding determine described in the position that is pressed.

Described step S1411a ' in, described fisrt feature point can be a described PPG information In target waveform on any point, convenient for statement, with described fisrt feature point in the application It is that a described PPG information illustrates as a example by the trough point on target waveform.

Described step S1412a ' in, described second feature point can be described 2nd PPG information In target waveform on any point, simple for the sake of, described second feature point is typically chosen correspondence The point of described fisrt feature point, is such as a described PPG information at described fisrt feature point In the case of trough point on middle target waveform, described second feature point can select described second Trough on target waveform point in PPG information.

Described step S1413a ' in, described in the position that is pressed be primary importance, the second position, In 3rd position and the 4th position one.Described primary importance, the second position, the 3rd position With the 4th position and described first detection position, the described second position relationship detecting position can With as shown in Figure 5.It will be seen that described primary importance, described first detection position, described 3rd position, described 4th position, described second detection position and described second position edge successively One reference direction distribution.Wherein, in Fig. 5, dotted line L represents described first detection position and described The middle vertical plane of the second detection position.It will be seen that described 3rd position is positioned at described middle vertical plane Near described first detection side, position, described 4th position is positioned at the close institute of described middle vertical plane State the second side, detection position.Wherein, described reference direction can be the arbitrary extension of described health It direction, such as Fig. 5 is the bearing of trend of an arm of user.It addition, described primary importance, The described second position, described 3rd position and described 4th position all can be understood as a class position Set, the most described primary importance be described in Fig. 5 first detection position on the left of a class position The set put, described 3rd position is between described first detection position and described middle vertical plane The set of class position.

Fig. 6 be primary importance when being pressed in the first detection position and the second detection station acquisition The oscillogram of the PPG information arrived.Wherein, abscissa represents sampled point sequence number, corresponding sampling Time, vertical coordinate represents the range value of PPG information.Upper curve represents at the first detecting position Putting the PPG waveform collected, lower curve represents the PPG collected in the second detection position Waveform.

It will be seen that corresponding 42706th sampling of fisrt feature point in a PPG information Point, corresponding 42730th sampled point of the second feature point in the 2nd PPG information, namely Say, fisrt feature point 24 sampled points of leading second feature point, each sampled point interval 4ms, Then fisrt feature point leading second feature point 96ms.

Inventor studies discovery, causes the reason of above-mentioned time difference to be, described first detecting position Put than described second detection position closer to described primary importance, therefore, when described first Putting when being pressed, its blood flow caused springs up and first involves the first detection position, the most just can ripple Shape second detects position.

Fig. 7 be the second position when being pressed in the first detection position and the second detection station acquisition The oscillogram of the PPG information arrived.It will be seen that in the figure, in a PPG information Corresponding 26413rd sampled point of fisrt feature point, the second feature point in the 2nd PPG information Corresponding 26381st sampled point, say, that fisrt feature point falls behind second feature point 32 Individual sampled point, each sampled point interval 4ms, then fisrt feature point falls behind second feature point 128ms.

Easy to understand, cause the reason of time difference in above-mentioned Fig. 7 to be, described first detecting position Put than described second detection position farther away from the described second position, therefore, when described second Putting when being pressed, its blood flow caused springs up and first involves the second detection position, the most just can ripple Shape first detects position.

Fig. 8 be the 3rd position when being pressed in the first detection position and the second detection station acquisition The oscillogram of the PPG information arrived.It will be seen that in the figure, in a PPG information Corresponding 72446th sampled point of fisrt feature point, the second feature point in the 2nd PPG information Corresponding 72452nd sampled point, say, that fisrt feature point leading second feature point 6 Sampled point, each sampled point interval 4ms, then fisrt feature point leading second feature point 24ms.

Easy to understand, cause the reason of time difference in above-mentioned Fig. 8 to be, described first detecting position Put than described second detection position closer to described 3rd position, therefore, when described 3rd Putting when being pressed, its blood flow caused springs up and first involves the first detection position, the most just can ripple Shape second detects position.

Fig. 9 be the 4th position when being pressed in the first detection position and the second detection station acquisition The oscillogram of the PPG information arrived.It will be seen that in the figure, in a PPG information Corresponding 65233rd sampled point of fisrt feature point, the second feature point in the 2nd PPG information Corresponding 65210th sampled point, say, that fisrt feature point falls behind second feature point 23 Individual sampled point, each sampled point interval 4ms, then fisrt feature point falls behind second feature point 92ms.

Easy to understand, cause the reason of time difference in above-mentioned Fig. 9 to be, described first detecting position Put than described second detection position farther away from described 4th position, therefore, when described 4th Putting when being pressed, its blood flow caused springs up and first involves the second detection position, the most just can ripple Shape first detects position.

According to above-mentioned experiment, can obtain, when a position is pressed, be pressed apart from this Nearer position, position is relatively early affected, thus described target waveform relatively early detected, therefore, In one embodiment, described step S1413a ' may further include:

S14131a ': in response to the difference of described second time Yu the described very first time be on the occasion of, The position being pressed described in determining is described primary importance or described 3rd position.

The difference of described second time and the described very first time be on the occasion of, then it represents that described first spy Levy and a little lead over described second feature point, thus described first detection position is than described second detection Position closer to the described position being pressed, may determine that accordingly described in the position that is pressed be Described primary importance or described 3rd position.In other words, it may be determined that described in the position that is pressed Setting in the left side of dotted line in Fig. 5.

Easy to understand, primary importance described in Fig. 5 and the described second position are symmetrical about dotted line L, Described first detection position and described second detection position are symmetrical about dotted line L, and the described 3rd Position and described 4th position are symmetrical about dotted line L, therefore can obtain, in response to described the The difference of one time and described second time be on the occasion of, determine described in the position that is pressed be described The second position or described 4th position.In other words, in response to described second time and described the The difference of one time is negative value, determine described in the position that is pressed be the described second position or described 4th position.It addition, based on above-mentioned three groups of symmetrical relationss, the position on the right side of dotted line L can be with base In with dotted line L on the left of similar principle be identified, the application hereafter emphasis is to dotted line L The location recognition in left side illustrates.

Thus, positive and negative according to described second time and the difference of the described very first time, the most permissible The position being pressed described in determining is positioned at left side or the right side of described dotted line L.

In some embodiments, it is only necessary to determine described in the position that is pressed be positioned at described dotted line The left side of L or right side, in other embodiments, in addition it is also necessary to carry out further really The position being pressed described in Ding is primary importance or the 3rd position.Therefore, implement at another kind In mode, described step S1413a ' may further include:

S14132a ': in response to the difference of described second time and the described very first time more than 1 the One threshold value, determine described in the position that is pressed be described primary importance.

And in another embodiment, described step S1413a ' may further include:

S14133a ': be just in response to the difference between described second time and the described very first time Value and less than a Second Threshold, determine described in the position that is pressed be described 3rd position.

Comparison diagram 6 and Fig. 8 it is found that when described be pressed position be described primary importance time, Fisrt feature point leading second feature point 96ms in Fig. 6, and being pressed position described in working as is institute When stating three positions, fisrt feature point leading second feature point 24ms in Fig. 8.At these two In the experimentation that figure is corresponding, user presses described primary importance and the dynamics of described 3rd position Essentially identical, arm posture keeps constant, it can be seen that fisrt feature point and second in Fig. 6 The time difference of characteristic point is significantly greater than fisrt feature point and the time difference of second feature point in Fig. 8. Inventor studies discovery, causes two visibly different reasons of time difference in above-mentioned Fig. 6 and Fig. 8 It is: described primary importance to described first detection position and the distance of described second detection position Difference, with described 3rd position to described first detection position and the distance of described second detection position Difference difference.

In fig. 5 it may be seen that described primary importance to the distance that described first detects position is D11, described primary importance is D12 to the distance of described second detection position, two distances Difference is D12-D11=D0；Described 3rd position to the distance of described first detection position is D31, described 3rd position is D32 to the distance of described second detection position, two distances Difference is D32-D31 < D0.The difference of the most above-mentioned range difference, result in Fig. 6 and Fig. 8 Two time differences are significantly different.

Inventor finds in research process, when the described position being pressed is described primary importance, When being the position on the left of described first detection position, press surging in holding essentially identical, hands In the case of arm attitude is essentially identical, described second time obtained and the difference of the described very first time It is worth the most essentially identical, and this difference can be all higher than described first threshold.Described first threshold, Can be according under pressed state, blood flow is flow to described second inspection by described first detection position The time that location is put, determined by training in advance.

It should be noted that except distance, be likely to affect blood by surging, body posture etc. Flow by the time of described first detection position to described second detection position, therefore, in order to improve Recognition accuracy, it is also possible to simultaneously consider to arrange by the factor such as surging, body posture described First threshold.It addition, be likely to the Second Threshold affected hereinafter by surging, body posture etc. Deng setting, but due to its non-the application emphasis, be no longer described in detail.

When the described position being pressed is described three position, press the basic phase of surging in holding With, in the case of arm attitude is essentially identical, when described second time obtained is with described first Between difference can different with the difference of position, meanwhile, this time difference can more than zero and be less than described Second Threshold.Described Second Threshold can be identical with described first threshold, it is also possible to setting little In described first threshold.

Owing to when the described position being pressed is described three position, pressing surging base in holding This is the most identical, in the case of arm attitude is essentially identical, and described second time obtained and described the The difference of one time can be different with the difference of position.Therefore, in another embodiment, institute State the 3rd position and include many sub-positions；Described step S1413a ' farther include:

S14134a ': according to the difference between described second time and the described very first time described Many sub-positions determine one as described in the position that is pressed.

In this step, can determine, in conjunction with a reference information, the sub-position that described difference is corresponding.Institute State reference information and include the corresponding relation between multiple reference difference and the plurality of sub-position, its Can be predetermined by training.

In another embodiment, described at least two PPG information is three PPG information, Described step S141a may include that

S141a ": detect a PPG information corresponding to position, the second detecting position according to first The 3rd PPG information that the 2nd PPG information putting correspondence detects position corresponding with the 3rd determines institute State the position being pressed.

In one embodiment, this step S141a " can be further:

S1411a ": in a described PPG information, determine one first spy that described pressing is corresponding Levy a little；

S1412a ": in described 2nd PPG information, determine one second spy that described pressing is corresponding Levy a little；

S1413a ": in described 3rd PPG information, determine one the 3rd spy that described pressing is corresponding Levy a little；

S1414a ": according to the very first time corresponding to described fisrt feature point, described second feature Threeth time corresponding with described third feature point the second time that point is corresponding determine described by by The position of pressure.

Described step S1411a ", S1412a ", S1413a " realize principle and described step S1411a ' or S1412a ' to realize principle identical, repeat no more.Further, simple for the sake of, should In embodiment, described fisrt feature point, described second feature point and described third feature point are also All select the trough point of target waveform in corresponding PPG information.

Described step S1414a " in, described in the position that is pressed be primary importance, the second position, In 3rd position, the 4th position, the 5th position and the 6th position one.Described primary importance, The described second position, described 3rd position, described 4th position, described 5th position and described 6th position and described first detection position, described second detection position and described 3rd detection The position relationship of position can be as shown in Figure 10.It will be seen that it is described 6th position, described 3rd detection position, described 5th position, described primary importance, described first detection position, Described 3rd position, described 4th position, described second detection position and the described second position depend on Secondary along a reference direction distribution.Wherein, in Figure 10, dotted line L1 represents described first detection position With the middle vertical plane of described second detection position, dotted line L2 represents described in described first detection position The middle vertical plane of the 3rd detection position.It will be seen that described 3rd position is positioned at middle vertical plane L1's Near described first detection side, position, described 4th position is positioned at leaning on of described middle vertical plane L1 The most described second detection side, position；Described 5th position is positioned at the close described of middle vertical plane L2 3rd detection side, position, described primary importance is positioned at close described the of described middle vertical plane L2 One detection side, position.It is similar to embodiment corresponding to Fig. 5, described primary importance, described The second position, described 3rd position, described 4th position, described 5th position and the described 6th Position all can be understood as the set of a class position.

It will be appreciated by those skilled in the art that in present embodiment, substantially by first in Fig. 5 Position is further divided into the primary importance of present embodiment, the 5th position and the 6th position, its His position is the most unaffected.Therefore, for the described second position, described 3rd position and described The identification of the 4th position can complete according to the principle in embodiment corresponding for Fig. 5, the most superfluous State, hereafter stress how primary importance, the 5th position and the 6th of present embodiment Put the position being pressed described in identification.

In one embodiment, described step S1414a " may include that

S14141a ": in response to the difference of the described very first time Yu described 3rd time be on the occasion of, The position being pressed described in determining is described 5th position or described 6th position.

This step realize principle and described step S14131a ' to realize principle identical, the most superfluous State.

In another embodiment, described step S1414a " can also include:

S14142a ": in response to the difference of the described very first time and described 3rd time more than 1 the Three threshold values, determine described in the position that is pressed be described 6th position.

This step realize principle and described step S14132a ' to realize principle identical, the most superfluous State.Wherein, described 3rd threshold value, can be according under pressed state, blood flow is by the described 3rd Detection position flow to the time of described first detection position, is determined by training in advance.

In another embodiment, described step S1414a " can also include:

S14143a ": in response to the difference between the described very first time and described 3rd time be On the occasion of and less than one the 4th threshold value, determine described in the position that is pressed be described 5th position.

This step realize principle and described step S14133a ' to realize principle identical, the most superfluous State.Wherein, described 4th threshold value, can be identical with described 3rd threshold value, or less than described 3rd threshold value.

In another embodiment, described step S1414a " can also include:

S14144a ": the difference in response to described second time with the described very first time is more than one First threshold, and the difference of the described very first time and described 3rd time is negative value, determines described The position being pressed is described primary importance.

In this step, in response to described second time with the difference of the described very first time more than described First threshold, it may be determined that described in the position that is pressed be primary importance, the 5th position or the 6th Position, and the difference being simultaneously in response to the described very first time and described 3rd time is negative value, then The position being pressed described in may further determine that is described primary importance.

Certainly, in present embodiment, described 5th position or primary importance can also be the thinnest Being divided into many sub-positions, a step of going forward side by side is identified.Such as can according to the described very first time and The difference of described 3rd time identifies many sub-positions included by described 5th position further.

It addition, it will be appreciated by those skilled in the art that described method can also pass by increasing PPG The quantity of sensor, increases further the quantity of detection position, thus strengthens the position that is pressed Accuracy of identification.Such as, often increase a PPG sensor in the side of existing PPG sensor, Then accordingly the location sets of this side is further divided into three subclass.

It addition, in above-mentioned embodiment, described in the position that is pressed and the detection of described at least two Position the most on the same line, as a example by Fig. 5, advantage of this is that, described primary importance, The described second position, described 3rd position and described 4th position, these four location sets correspondences Region the most easily distinguish, can carry out clear and definite according to the described very first time and described second time Identify, i.e. do not have a situation of the corresponding two or more location sets of recognition result, thus When user is by pressing input information, it is easily mastered the correspondence between diverse location and different information Relation, is difficult to obscure.Certainly, the most on the same line, refer to substantially at same straight line On, can there is certain error tolerance.

The position being pressed described in it addition, and described at least two detection position be not at same straight line On, described method also can't be caused not implement, simply the most in this case, described in be pressed The region of optional location sets corresponding to position divide and be not apparent from, in this case, can Extra equipment auxiliary can be needed to carry out region division.Such as can be by user's body upslide The mode of shadow is to divide different regions, and then user can control pressing according to the prompting of projection Different regions, to input different information.

B), in one embodiment, described blood flow information is Doppler measurement information, described Doppler measurement information can be such as LDF (laser Doppler shift), LDV (Laser Doppler Velocimetry, LDV), supersonic Doppler frequency displacement etc., its bag Include a series of Envelop waves signal, it is carried out such as fast Fourier transform and can obtain correspondence Frequency-region signal, the doppler-frequency component in described frequency-region signal is proportional to blood flow rate, from And the blood flow that causes of described pressing springs up and can cause Doppler frequency occur in described frequency-region signal Significantly increasing of component.

Corresponding described step S141 is further:

S141b: according at least to described at least two Doppler measurement information determine described in be pressed Position.

Figure 11 is the LDF information and the schematic diagram of frequency domain information thereof collected under normal circumstances, Wherein, it is LDF waveform above dotted line, is corresponding frequency domain information below dotted line.Described frequency Domain information can obtain in the following manner: described LDF information is divided according to scheduled duration Become many sub-information, use the modes such as Fourier transformation to carry out frequency domain conversion every sub-information, Thus obtain described frequency domain information.Wherein, described scheduled duration is the least, the knowledge of the most described method Other precision is the highest, such as could be arranged to 4ms.It addition, except as shown in figure 11 to described Beyond LDF information divides according to scheduled duration, it is also possible to use sliding according to a pre-fixed step size Described LDF information is converted to multiple frequency domain informations of correspondence by the mode of dynamic time window.Letter For the sake of list, the application only illustrates as a example by dividing mode shown in Figure 11.

It addition, when push action occurs, the frequency that the LDF information that collects is corresponding can be caused Domain information occurs that obvious frequency is remote, hereinafter will be described in detail with reference to the accompanying drawings.

In one embodiment, described at least two Doppler measurement information is just more than two General Le metrical information, described step S141b may include that

S141b ': the first Doppler measurement information corresponding according to the first detection position and the second inspection Location put the second Doppler measurement information of correspondence determine described in the position that is pressed.

In one embodiment, described step S141b ' can be further:

S1411b ': determine in described first Doppler measurement information that described pressing is corresponding one the One time；

S1412b ': determine in described second Doppler measurement information that described pressing is corresponding one the Two times；

S1413b ': according to the described very first time and described second time determine described in be pressed Position.

Described step S1411b ' in, the described very first time is that described first detection position detects The time of described push action, or perhaps described push action has influence on described first detecting position The time put.Described first Doppler measurement information can be pressed by it according to as shown in figure 11 It is divided into many sub-information according to scheduled duration, then each sub-information is carried out frequency domain conversion, root Determine that according to frequency domain information moment frequency shift (FS) occur is as the described very first time.

Described step S1412b ' in, described second time is that described second detection position detects The time of described push action, or perhaps described push action has influence on described second detecting position The time put.Described second time can according to described step S1411b ' similar principle Determine.

Described step S1413b ' in, described in the position that is pressed be primary importance, the second position, In 3rd position and the 4th position one.Described primary importance, the second position, the 3rd position With the 4th position and described first detection position, the described second position relationship detecting position can With as shown in Figure 5.It will be seen that described primary importance, described first detection position, described 3rd position, described 4th position, described second detection position and described second position edge successively One reference direction distribution.Wherein, in Fig. 5, dotted line L represents described first detection position and described The middle vertical plane of the second detection position.It will be seen that described 3rd position is positioned at described middle vertical plane Near described first detection side, position, described 4th position is positioned at the close institute of described middle vertical plane State the second side, detection position.Wherein, described reference direction can be the arbitrary extension of described health It direction, such as Fig. 5 is the bearing of trend of an arm of user.It addition, described primary importance, The described second position, described 3rd position and described 4th position all can be understood as a class position Set, the most described primary importance be described in Fig. 5 first detection position on the left of a class position The set put, described 3rd position is between described first detection position and described middle vertical plane The set of class position.

Figure 12 a and Figure 12 b is that primary importance detects position and second respectively at first when being pressed The schematic diagram of the frequency domain information of the detection LDF information that collects of position and correspondence thereof.Can see Arriving, in Figure 12 a, sub-information C2, the frequency domain information of C3 occur in that obvious frequency shift (FS). The blood flow that this most described pressing causes springs up the impact on Doppler measurement information, the most permissible Determine the described very first time.Meanwhile, in Figure 12 b, sub-information C26, C27 and C28 Frequency domain information occurs in that obvious frequency shift (FS).Contrast is it is found that Figure 12 a and Figure 12 b In two groups of LDF information, the time of frequency of occurrences skew is significantly different.

Wherein, for how determining time corresponding to described pressing (the most described very first time or the Two times) can there is multiple strategy: such as can be the time catch cropping of frequency shift (FS) to be detected at first For the time that described pressing is corresponding, or can be with the frequency offset that detects maximum time As the time etc. that described pressing is corresponding.If using detect at first time of frequency shift (FS) as The time that described pressing is corresponding, a threshold value can be set, when the frequency shift (FS) of a certain sub-information When amount is more than this threshold value, i.e. think that this sub-information correspondence moment is the described time pressing correspondence. If pressing the corresponding time using the time that the frequency offset detected is maximum as described, can To select a maximum correspondence in all frequency offsets information more than described threshold value Time as time corresponding to described pressing, as a example by Figure 12 b, then should select C27 The corresponding time.For the sake of Jian Dan, the application all using detect at first time of frequency shift (FS) as Illustrate as a example by the time that described pressing is corresponding, i.e. with time catch cropping that C2 is corresponding in Figure 12 a For the described very first time, using the time corresponding for C26 as described second time in Figure 12 b.Real In testing, time a length of 4ms that every sub-information is corresponding, then can obtain the described very first time in institute Before stating for the second time, its time difference 96ms.

Figure 13 a and Figure 13 b is that the second position detects position and second respectively at first when being pressed The schematic diagram of the frequency domain information of the detection LDF information that collects of position and correspondence thereof.Can see Arriving, the described very first time is the time corresponding for C34 in Figure 13 a, and described second time is figure Time corresponding for C2 in 13b.In experiment, time a length of 4ms that every sub-information is corresponding, then The described very first time can be obtained after described second time, its time difference 128ms.

Easy to understand, cause the reason of time difference in above-mentioned Figure 13 a and Figure 13 b to be, described First detects position than described second detection position farther away from the described second position, therefore, when When the described second position is pressed, its blood flow caused springs up and first involves the second detection position, The most just can detect position by waveform first.

Figure 14 a and Figure 14 b is that position and second is detected respectively at first when being pressed in the 3rd position The schematic diagram of the frequency domain information of the detection LDF information that collects of position and correspondence thereof.Can see Arriving, the described very first time is the time corresponding for C2 in Figure 14 a, and described second time is Figure 14 b The time that middle C8 is corresponding.In experiment, time a length of 4ms that every sub-information is corresponding, the most permissible Obtained the described very first time before described second time, its time difference 24ms.

Easy to understand, cause the reason of time difference in above-mentioned Figure 14 a and Figure 14 b to be, described First detects position than described second detection position closer to described 3rd position, therefore, when When described 3rd position is pressed, its blood flow caused springs up and first involves the first detection position, The most just can detect position by waveform second.

Figure 15 a and Figure 15 b is that position and second is detected respectively at first when being pressed in the 4th position The schematic diagram of the frequency domain information of the detection LDF information that collects of position and correspondence thereof.Can see Arriving, the described very first time is the time corresponding for C25 in Figure 15 a, and described second time is figure Time corresponding for C2 in 15b.In experiment, time a length of 4ms that every sub-information is corresponding, then The described very first time can be obtained after described second time, its time difference 92ms.

Easy to understand, cause the reason of time difference in above-mentioned Figure 15 a and Figure 15 b to be, described First detects position than described second detection position farther away from described 4th position, therefore, when When described 4th position is pressed, its blood flow caused springs up and first involves the second detection position, The most just can detect position by waveform first.

According to above-mentioned experiment, can obtain, when a position is pressed, be pressed apart from this Nearer position, position is relatively early affected, thus relatively early frequency shift (FS) detected, therefore, In a kind of embodiment, described step S1413b ' may further include:

S14131b ': in response to the difference of described second time Yu the described very first time be on the occasion of, The position being pressed described in determining is described primary importance or described 3rd position.

The difference of described second time and the described very first time be on the occasion of, then it represents that described first examines Location is put than described second detection position closer to the described position being pressed, accordingly can be true The position being pressed described in Ding is described primary importance or described 3rd position.In other words, may be used It is positioned at the left side of dotted line in Fig. 5 with the position being pressed described in determining.

In some embodiments, it is only necessary to determine described in the position that is pressed be positioned at described dotted line The left side of L or right side, in other embodiments, in addition it is also necessary to carry out further really The position being pressed described in Ding is primary importance or the 3rd position.Therefore, implement at another kind In mode, described step S1413b ' may further include:

S14132b ': in response to the difference of described second time and the described very first time more than 1 the One threshold value, determine described in the position that is pressed be described primary importance.

And in another embodiment, described step S1413b ' may further include:

S14133b ': be just in response to the difference between described second time and the described very first time Value and less than a Second Threshold, determine described in the position that is pressed be described 3rd position.

By Figure 12 a and Figure 12 b it is found that being pressed position described in Dang is described first When putting, the very first time is 96ms before the second time；Can be sent out by Figure 14 a and Figure 14 b Existing, when described be pressed position be described three position time, the very first time is before the second time 24ms.In the experimentation that these 4 figures are corresponding, user presses described primary importance and described The dynamics of the 3rd position is essentially identical, and arm posture keeps constant, it can be seen that primary importance The corresponding very first time is significantly greater than first that the 3rd position is corresponding with the time difference of the second time Time and the time difference of the second time.Inventor studies discovery, causes above-mentioned two time difference bright Aobvious different reason is: described primary importance to described first detection position and described second inspection The range difference that location is put, with described 3rd position to described first detection position and described second inspection The range difference that location is put is different.

In fig. 5 it may be seen that described primary importance to the distance that described first detects position is D11, described primary importance is D12 to the distance of described second detection position, two distances Difference is D12-D11=D0；Described 3rd position to the distance of described first detection position is D31, described 3rd position is D32 to the distance of described second detection position, two distances Difference is D32-D31 < D0.The difference of the most above-mentioned range difference, above-mentioned two time difference is obvious Different.

Owing to when the described position being pressed is described three position, pressing surging base in holding This is the most identical, in the case of arm attitude is essentially identical, and described second time obtained and described the The difference of one time can be different with the difference of position.Therefore, in another embodiment, institute State the 3rd position and include many sub-positions；Described step S1413b ' farther include:

S14134b ': according to the difference between described second time and the described very first time described Many sub-positions determine one as described in the position that is pressed.

In another embodiment, described at least two Doppler measurement information is general more than three Strangling metrical information, described step S141b may include that

S141b ": detect the first Doppler measurement information corresponding to position, the second inspection according to first Location puts more than threeth general corresponding with the 3rd detection position of the second Doppler measurement information of correspondence Strangle metrical information determine described in the position that is pressed.

In one embodiment, this step S141b " can be further:
