It will be appreciated by those skilled in the art that in embodiments herein, the sequence number of following each steps 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 should not constitute any restriction to the implementation process of the embodiment of the present application.

Inventor finds in research process, if held at the last position of body (such as arm) Row one presses, and this pressing can lead to the blood flow burst at position nearby to spring up, and then make to collect Blood flow information changes.And, if set gradually two biographies in the side being pressed position Sensor, this two sensors can detect this blood flow burst in different time points and spring up.Enter One step, if change the relative position of pressing position and test position, this two sensors The possible change of time relationship (such as sequencing) that this blood flow burst springs up is detected.Base In this, the position being pressed then can be identified according to the blood flow information that this two sensors obtain, And then can determine the corresponding input information in the position being accordingly pressed.Wherein, described blood flow letter Breath can be ppg (photoplethysmography, photoplethysmographic) information, or Person can also be Doppler measurement information, such as ldf (laser doppler flowmetry, Laser-Doppler flow velocity) information.

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

S120: be pressed in response to a position on body, at least two detections of described body Position obtains a blood flow information respectively, obtains at least two blood flow informations；

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

The embodiment of the present application methods described, is pressed in response to a position on body, in described body At least two test positions of body obtain a blood flow information respectively, obtain at least two blood flow informations, Then determine an input information according at least to described at least two blood flow informations.Thus providing one Plant the method that input information is determined based on the blood flow information of at least two test positions, methods described Improve the input capability of the electronic equipments such as Wearable.

Below with reference to specific embodiment, describe the work(of described step s120 and s140 in detail Energy.

S120: be pressed in response to a position on body, at least two detections of described body Position obtains a blood flow information respectively, obtains at least two blood flow informations.

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

Described position and described at least two test positions 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 affects substantially to rise See, the described position being pressed and described at least two test positions are preferably same in described body 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 the position being pressed described in described at least two blood flow informations determinations；

S142: the corresponding described input information in position being pressed described in determination

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 the position being pressed described in described at least two ppg information determinations.

Fig. 2 is the waveform diagram of the ppg information collecting under normal circumstances, and it presents bright Aobvious cyclically-varying, can reflect the health indicators such as the heart rate of collected object.Fig. 3 be The waveform diagram of the ppg information collecting when being pressed near test position, wherein oval The corresponding push action of interior waveform is it can be seen that this portion waveshape occurs in that obvious range value Decline, this is to lead to the blood volume near test position to increase suddenly due to push action.

Wherein it is possible to the local by this corresponding push action of waveform in ellipse in similar Fig. 3 Waveform is denoted as target waveform.Then 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.

In addition, in some cases, if the push action corresponding moment is just in normal ppg Should the moment of crest in waveform, then may lead to the ellipse in described target waveform such as Fig. 4 Waveform in region.In this case although push action also leads to the amplitude of ppg waveform Value substantially reduces, but the range value after its reduction is still 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, described target ripple is identified according to result of calculation Shape.

Still taking waveform shown in Fig. 4 as a example, can be according to being a cycle between adjacent trough, will Waveform shown in Fig. 4 is divided into c1, c2, c3, c4, c5, altogether 5 sub-waveform, and this 5 Individual sub-waveform corresponds to 5 sub- ppg information.Wherein, the waveform of marginal portion can be ignored, This is because when gathering described ppg information, can excessively gather some ppg information.

Described can be between two troughs collecting under normal circumstances with reference to ppg information Ppg waveform, is carried out mutually with above-mentioned 5 sub- ppg information with reference to ppg information respectively by described It is found that the described cross-correlation calculation result with reference to ppg information and c3 after correlation computations It is significantly less than the described cross-correlation calculation result with reference to ppg information and other sub- ppg information, May determine that the corresponding sub- ppg information of c3 is described target waveform accordingly.

In practical application, can be described mutual with reference to ppg information ppg with each information Correlation calculation result is compared with a threshold value, 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 reference ppg letter Breath and the 80% of the cross-correlation calculation result of itself.

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

In one embodiment, described at least two ppg information are just two ppg letters Breath, described step s141a may include that

S141a ': according to the corresponding ppg information of the first test position and the second test position The position being pressed described in corresponding 2nd ppg information determination.

In one embodiment, described step s141a ' can be further:

S1411a ': determine corresponding one first spy of described pressing in a described ppg information Levy a little；

S1412a ': determine corresponding one second spy of described pressing in described 2nd ppg information Levy a little；

S1413a ': according to the described fisrt feature point corresponding very first time and described second feature The position being pressed described in the corresponding second time determination of point.

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 to illustrate as a example the trough point on target waveform in a described ppg information.

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 a described ppg information such as in described fisrt feature point In the case of trough point on middle target waveform, described second feature point can select described second Trough point on target waveform in ppg information.

Described step s1413a ' in, the described position that is pressed be primary importance, the second position, One of 3rd position and the 4th position.Described primary importance, the second position, the 3rd position Can with the position relationship of the 4th position and described first test position, described second test position With as shown in Figure 5.Can see, described primary importance, described first test position, described 3rd position, described 4th position, described second test position and described second position edge successively One reference direction distribution.Wherein, in Fig. 5, dotted line l represents described first test position and described The middle vertical plane of the second test position.Can see, described 3rd position is located at described middle vertical plane Near described first test position side, described 4th position is located at the close institute of described middle vertical plane State the second test position side.Wherein, described reference direction can be the arbitrary extension of described body It is the bearing of trend of an arm of user in direction, such as Fig. 5.In addition, described primary importance, The described second position, described 3rd position and described 4th position all can be understood as a class position Set, such as described primary importance is the class position on the left of the first test position described in Fig. 5 The set put, described 3rd position is between described first test position and described middle vertical plane The set of class position.

Fig. 6 is to gather in the first test position and the second test position when primary importance is pressed The oscillogram of the ppg information arriving.Wherein, abscissa represents sampled point sequence number, corresponding sampling Time, vertical coordinate represents the range value of ppg information.Upper curve represents in the first detecting position Put the ppg waveform collecting, lower curve represents the ppg collecting in the second test position Waveform.

Can see, corresponding 42706th sampling of the fisrt feature point in a ppg information Point, the second feature point in the 2nd ppg information corresponds to the 42730th sampled point, that is, Say, fisrt feature point 24 sampled points of leading second feature point, each sampled point is spaced 4ms, Then fisrt feature point leading second feature point 96ms.

Inventor's research finds, is the reason lead to above-mentioned time difference, described first detecting position Put than described second test position closer to described primary importance, therefore, when described first Put when being pressed, the blood flow that it causes springs up and involves the first test position first, then just can ripple Shape second test position.

Fig. 7 is to gather in the first test position and the second test position when the second position is pressed The oscillogram of the ppg information arriving.Can see, in the figure, in a ppg information Fisrt feature point corresponds to the 26413rd sampled point, the second feature point in the 2nd ppg information Corresponding 26381st sampled point is that is to say, that fisrt feature point falls behind second feature point 32 Individual sampled point, each sampled point is spaced 4ms, then fisrt feature point falls behind second feature point 128ms.

Easy to understand, it is the reason lead to time difference in above-mentioned Fig. 7, described first detecting position Put than described second test position farther away from the described second position, therefore, when described second Put when being pressed, the blood flow that it causes springs up and involves the second test position first, then just can ripple Shape first test position.

Fig. 8 is to gather in the first test position and the second test position when the 3rd position is pressed The oscillogram of the ppg information arriving.Can see, in the figure, in a ppg information Fisrt feature point corresponds to the 72446th sampled point, the second feature point in the 2nd ppg information Corresponding 72452nd sampled point is that is to say, that fisrt feature point leading second feature point 6 Sampled point, each sampled point is spaced 4ms, then fisrt feature point leading second feature point 24ms.

Easy to understand, it is the reason lead to time difference in above-mentioned Fig. 8, described first detecting position Put than described second test position closer to described 3rd position, therefore, when described 3rd Put when being pressed, the blood flow that it causes springs up and involves the first test position first, then just can ripple Shape second test position.

Fig. 9 is to gather in the first test position and the second test position when the 4th position is pressed The oscillogram of the ppg information arriving.Can see, in the figure, in a ppg information Fisrt feature point corresponds to the 65233rd sampled point, the second feature point in the 2nd ppg information Corresponding 65210th sampled point is that is to say, that fisrt feature point falls behind second feature point 23 Individual sampled point, each sampled point is spaced 4ms, then fisrt feature point falls behind second feature point 92ms.

Easy to understand, it is the reason lead to time difference in above-mentioned Fig. 9, described first detecting position Put than described second test position farther away from described 4th position, therefore, when described 4th Put when being pressed, the blood flow that it causes springs up and involves the second test position first, then just can ripple Shape first test position.

According to above-mentioned experiment, can obtain, when a position is pressed, be pressed apart from this The nearer position in position is more early affected, thus relatively early detect described target waveform, therefore, In one embodiment, described step s1413a ' may further include:

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

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

Easy to understand, primary importance described in Fig. 5 and the described second position are symmetrical with regard to dotted line l, Described first test position and described second test position are symmetrical with regard to dotted line l, and the described 3rd Position and described 4th position are symmetrical with regard to dotted line l, therefore can obtain, in response to described the One time was on the occasion of the position being pressed described in determination is described with the difference of described second time 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, and the position being pressed described in determination is the described second position or described 4th position.In addition, being 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 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, you can with The position being pressed described in determination is located at left side or the right side of described dotted line l.

In some embodiments, it is only necessary to determine the described position being pressed is located at described dotted line The left side of l or right side, in addition it is also necessary to carry out further really in other embodiments The position being pressed described in fixed is primary importance or the 3rd position.Therefore, implement another kind of In mode, described step s1413a ' may further include:

S14132a ': the difference in response to described second time and the described very first time is more than one the One threshold value, the position being pressed described in determination is described primary importance.

And in another embodiment, described step s1413a ' may further include:

S14133a ': in response to the difference between described second time and the described very first time for just It is worth and is less than a Second Threshold, the position being pressed described in determination is described 3rd position.

Contrast Fig. 6 and Fig. 8 it is found that when described be pressed position be described primary importance when, Fisrt feature point leading second feature point 96ms in Fig. 6, and described ought be pressed position for institute When stating three positions, fisrt feature point leading second feature point 24ms in Fig. 8.At this two Scheme in corresponding experimentation, user presses described primary importance and the dynamics of described 3rd position Essentially identical, arm posture keep constant it can be seen that fisrt feature point and second in Fig. 6 The time difference of characteristic point is significantly greater than the time difference of fisrt feature point and second feature point in Fig. 8. Inventor's research finds, causes the reason in above-mentioned Fig. 6 and Fig. 8, two time differences are significantly different It is: described primary importance is to the distance of described first test position and described second test position Difference, the distance with described 3rd position to described first test position and described second test position Difference is different.

In fig. 5 it may be seen that the distance of described primary importance to described first test position is D11, the distance of described primary importance to described second test position is d12, two distances Difference is d12-d11=d0；The distance of described 3rd position to described first test position is D31, the distance of described 3rd position to described second test position is d32, two distances Difference is d32-d31 < d0.The difference of exactly 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 test position, keeping, pressing dynamics is essentially identical, handss In the case that arm attitude is essentially identical, the difference of described second time of obtaining and the described very first time Value is also essentially identical, and this difference can be all higher than described first threshold.Described first threshold, Can be according under pressed state, blood flow flow to described second inspection by described first test position The time that location is put, determined by training in advance.

It should be noted that except distance, pressing dynamics, body posture etc. are likely to affect blood Flow by the time of described first test position to described second test position, therefore, in order to improve Recognition accuracy is it is also possible to consider the factors such as pressing dynamics, body posture and arrange described simultaneously First threshold.In addition, pressing dynamics, body posture etc. are likely to affect Second Threshold hereinafter 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, keeping the basic phase of pressing dynamics With in the case that arm attitude is essentially identical, when described second time of obtaining 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 identical with described first threshold it is also possible to setting little In described first threshold.

Due to when the described position being pressed is described three position, keeping pressing dynamics base This is identical, in the case that arm attitude is essentially identical, described second time of obtaining 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 ' further include:

S14134a ': according to the difference between described second time and the described very first time described One is determined as the described position being pressed in many sub- positions.

In this step, the corresponding sub- position of described difference can be determined in conjunction with a reference information.Institute State the corresponding relation that reference information includes 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 are three ppg information, Described step s141a may include that

S141a ": according to the corresponding ppg information of the first test position, the second detecting position Put corresponding 2nd ppg information and the corresponding 3rd ppg information of the 3rd test position determines institute State the position being pressed.

In one embodiment, this step s141a " can be further:

S1411a ": determine corresponding one first spy of described pressing in a described ppg information Levy a little；

S1412a ": determine corresponding one second spy of described pressing in described 2nd ppg information Levy a little；

S1413a ": determine corresponding one the 3rd spy of described pressing in described 3rd ppg information Levy a little；

S1414a ": according to the described fisrt feature point corresponding very first time, described second feature Point corresponding second time and described third feature point corresponding 3rd time determine described by by The position of pressure.

Described step s1411a ", s1412a ", s1413a " realizes principle and described step S1411a ' or s1412a ' to realize principle identical, repeat no more.And, for the sake of simple, should In embodiment, described fisrt feature point, described second feature point and described third feature point All select the trough point of target waveform in corresponding ppg information.

In described step s1414a ", the described position that is pressed be primary importance, the second position, One of 3rd position, the 4th position, the 5th position and the 6th position.Described primary importance, The described second position, described 3rd position, described 4th position, described 5th position and described 6th position and described first test position, described second test position and described 3rd detection The position relationship of position can be as shown in Figure 10.Can see, described 6th position, described 3rd test position, described 5th position, described primary importance, described first test position, Described 3rd position, described 4th position, described second test position and the described second position according to Secondary along one reference direction be distributed.Wherein, in Figure 10, dotted line l1 represents described first test position With the middle vertical plane of described second test position, dotted line l2 represents described in described first test position The middle vertical plane of the 3rd test position.Can see, described 3rd position is located at middle vertical plane l1's Near described first test position side, described 4th position is located at leaning on of described middle vertical plane l1 Closely described second test position side；Described 5th position is located at the close described of middle vertical plane l2 3rd test position side, described primary importance is located at close described the of described middle vertical plane l2 One test position side.Similar to the corresponding embodiment of 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 simultaneously 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 the corresponding embodiment of Fig. 5, no longer superfluous State, hereafter stress how in the primary importance of present embodiment, the 5th position and the 6th Put the position being pressed described in identification.

In one embodiment, described step s1414a " may include that

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

This step realize principle and described step s14131a ' to realize principle identical, no longer superfluous State.

In another embodiment, described step s1414a " can also include:

S14142a ": the difference in response to the described very first time and described 3rd time is more than one the Three threshold values, the position being pressed described in determination is described 6th position.

This step realize principle and described step s14132a ' to realize principle identical, no longer superfluous State.Wherein, described 3rd threshold value, can be according under pressed state, and blood flow is by the described 3rd Test position flow to the time of described first test position, is determined by training in advance.

In another embodiment, described step s1414a " can also include:

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

This step realize principle and described step s14133a ' to realize principle identical, no longer 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 and 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 and the described very first time difference be more than described First threshold is it may be determined that the described position being pressed is primary importance, the 5th position or the 6th Position, and the difference being simultaneously in response to the described very first time with 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 thin further It is 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.

In addition, it will be appreciated by those skilled in the art that methods described can also be passed by increasing ppg The quantity of sensor, increases the quantity of test position further, thus strengthening the position being 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 are further divided into three subclass.

In addition, in above-mentioned embodiment, the described position being pressed and described at least two detections Position all on the same line, advantage of this is that taking Fig. 5 as a example, described primary importance, The described second position, described 3rd position and described 4th position, this four location sets correspond to Region clearly easily distinguish, can be carried out clearly according to the described very first time and described second time Identification, that is, be not in the situation of the corresponding two or more location sets of recognition result, thus When user passes through to press input information, it is easily mastered the correspondence between diverse location and different information Relation, is difficult to obscure.Certainly, here on the same line, refer to substantially in same straight line On, can there is certain error tolerance.

In addition, the described position being pressed and described at least two test positions are not in same straight line On, methods described also can't be led to can not to implement, simply in this case, described be pressed The region division of position corresponding optional position set 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, carrying out such as fast Fourier transform to it can be corresponded to 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 lead to Doppler frequency in described frequency-region signal The significantly increasing of component.

Described step s141 is further accordingly:

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

Figure 11 is the schematic diagram of the ldf information and its frequency domain information collecting under normal circumstances, Wherein, it is ldf waveform above dotted line, be 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 multiple sub-informations, each sub-information carried out frequency domain conversion using modes such as Fourier transformations, Thus obtaining described frequency domain information.Wherein, described scheduled duration is less, then the knowledge of methods described Other precision is higher, such as could be arranged to 4ms.In addition, except as shown in figure 11 to described Beyond ldf information is divided according to scheduled duration, can also be according to a pre- fixed step size using cunning Described ldf information is converted to corresponding multiple frequency domain information by the mode of dynamic time window.Letter For the sake of list, the application only taking dividing mode shown in Figure 11 as a example illustrates.

In addition, when push action occurs, the corresponding frequency of ldf information collecting can be led to The obvious frequency of domain information appearance is remote, will be described in detail with reference to the accompanying drawings hereinafter.

In one embodiment, described at least two Doppler measurement information are just more than two General Le metrical information, described step s141b may include that

S141b ': according to the corresponding first Doppler measurement information of the first test position and the second inspection Location puts the position being pressed described in corresponding second Doppler measurement information determination.

In one embodiment, described step s141b ' can be further:

S1411b ': determine described pressing corresponding 1 the in described first Doppler measurement information One time；

S1412b ': determine described pressing corresponding 1 the in described second Doppler measurement information Two times；

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

Described step s1411b ' in, the described very first time is that described first test 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 multiple sub-informations according to scheduled duration, then frequency domain conversion, root are carried out to each sub-information Determine the moment that frequency shift (FS) occurs as the described very first time according to frequency domain information.

Described step s1412b ' in, described second time is that described second test 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, the described position that is pressed be primary importance, the second position, One of 3rd position and the 4th position.Described primary importance, the second position, the 3rd position Can with the position relationship of the 4th position and described first test position, described second test position With as shown in Figure 5.Can see, described primary importance, described first test position, described 3rd position, described 4th position, described second test position and described second position edge successively One reference direction distribution.Wherein, in Fig. 5, dotted line l represents described first test position and described The middle vertical plane of the second test position.Can see, described 3rd position is located at described middle vertical plane Near described first test position side, described 4th position is located at the close institute of described middle vertical plane State the second test position side.Wherein, described reference direction can be the arbitrary extension of described body It is the bearing of trend of an arm of user in direction, such as Fig. 5.In addition, described primary importance, The described second position, described 3rd position and described 4th position all can be understood as a class position Set, such as described primary importance is the class position on the left of the first test position described in Fig. 5 The set put, described 3rd position is between described first test position and described middle vertical plane The set of class position.

Figure 12 a and Figure 12 b is respectively at the first test position and second when primary importance is pressed Ldf information and its schematic diagram of corresponding frequency domain information that test position collects.Can see Arrive, in Figure 12 a, the frequency domain information of sub-information c2, c3 occurs in that obvious frequency shift (FS). The blood flow that this exactly described pressing leads to springs up the impact to Doppler measurement information, permissible accordingly Determine the described very first time.Meanwhile, in Figure 12 b, sub-information c26, c27 and c28's 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 described pressing corresponding time (the i.e. described very first time or the Two times) can there are multiple strategies: such as can be the when catch cropping of frequency shift (FS) be detected at first For the described pressing corresponding time, or can be with the frequency offset that the detects maximum time As described pressing corresponding time etc..If using detect at first time of frequency shift (FS) as The described pressing corresponding time, a threshold value can be set, when the frequency shift (FS) of some sub-information When amount is more than this threshold value, that is, think that this sub-information corresponding moment is the described pressing corresponding time. If using the frequency offset the detecting maximum time as the described pressing corresponding time, can Select a maximum correspondence to be more than in all frequency offsets in the sub-information of described threshold value Time as described pressing the corresponding time, then should select c27 taking Figure 12 b as a example The corresponding time.For the sake of simple, the application all using detect at first time of frequency shift (FS) as Described pressing the corresponding time as a example illustrate, that is, in Figure 12 a with c2 corresponding when catch cropping For the described very first time, using the c26 corresponding time as described second time in Figure 12 b.Real In testing, each sub-information a length of 4ms when 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 respectively at the first test position and second when the second position is pressed Ldf information and its schematic diagram of corresponding frequency domain information that test position collects.Can see Arrive, the described very first time is the c34 corresponding time in Figure 13 a, described second time is figure The c2 corresponding time in 13b.In experiment, each sub-information a length of 4ms when corresponding, then The described very first time can be obtained after described second time, its time difference 128ms.

Easy to understand, it is the reason lead to time difference in above-mentioned Figure 13 a and Figure 13 b, described First test position than described second test position farther away from the described second position, therefore, when When the described second position is pressed, the blood flow that it causes springs up and involves the second test position first, Then just can waveform first test position.

Figure 14 a and Figure 14 b is respectively at the first test position and second when the 3rd position is pressed Ldf information and its schematic diagram of corresponding frequency domain information that test position collects.Can see Arrive, the described very first time is the c2 corresponding time in Figure 14 a, described second time is Figure 14 b The middle c8 corresponding time.In experiment, each sub-information a length of 4ms when corresponding, then permissible Obtained the described very first time before described second time, its time difference 24ms.

Easy to understand, it is the reason lead to time difference in above-mentioned Figure 14 a and Figure 14 b, described First test position than described second test position closer to described 3rd position, therefore, when When described 3rd position is pressed, the blood flow that it causes springs up and involves the first test position first, Then just can waveform second test position.

Figure 15 a and Figure 15 b is respectively at the first test position and second when the 4th position is pressed Ldf information and its schematic diagram of corresponding frequency domain information that test position collects.Can see Arrive, the described very first time is the c25 corresponding time in Figure 15 a, described second time is figure The c2 corresponding time in 15b.In experiment, each sub-information a length of 4ms when corresponding, then The described very first time can be obtained after described second time, its time difference 92ms.

Easy to understand, it is the reason lead to time difference in above-mentioned Figure 15 a and Figure 15 b, described First test position than described second test position farther away from described 4th position, therefore, when When described 4th position is pressed, the blood flow that it causes springs up and involves the second test position first, Then just can waveform first test position.

According to above-mentioned experiment, can obtain, when a position is pressed, be pressed apart from this The nearer position in position is more early affected, thus relatively early detect frequency shift (FS), therefore, In a kind of embodiment, described step s1413b ' may further include:

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

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

In some embodiments, it is only necessary to determine the described position being pressed is located at described dotted line The left side of l or right side, in addition it is also necessary to carry out further really in other embodiments The position being pressed described in fixed is primary importance or the 3rd position.Therefore, implement another kind of In mode, described step s1413b ' may further include:

S14132b ': the difference in response to described second time and the described very first time is more than one the One threshold value, the position being pressed described in determination is described primary importance.

And in another embodiment, described step s1413b ' may further include:

S14133b ': in response to the difference between described second time and the described very first time for just It is worth and is less than a Second Threshold, the position being pressed described in determination is described 3rd position.

By Figure 12 a and Figure 12 b it is found that position described ought be pressed be described first When putting, very first time 96ms before the second time；Can be sent out by Figure 14 a and Figure 14 b Existing, when described be pressed position and be described three position when, the very first time is before the second time 24ms.Scheme in corresponding experimentation at this 4, user presses described primary importance and described The dynamics of the 3rd position is essentially identical, arm posture keep constant it can be seen that primary importance The time difference of the corresponding very first time and the second time is significantly greater than the 3rd position corresponding first Time and the time difference of the second time.Inventor's research finds, causes above-mentioned two time difference bright Aobvious different the reason, is: described primary importance to described first test position and described second inspection The range difference that location is put, with described 3rd position to described first test position and described second inspection The range difference that location is put is different.

In fig. 5 it may be seen that the distance of described primary importance to described first test position is D11, the distance of described primary importance to described second test position is d12, two distances Difference is d12-d11=d0；The distance of described 3rd position to described first test position is D31, the distance of described 3rd position to described second test position is d32, two distances Difference is d32-d31 < d0.The difference of exactly above-mentioned range difference, above-mentioned two time difference is obvious Different.

Due to when the described position being pressed is described three position, keeping pressing dynamics base This is identical, in the case that arm attitude is essentially identical, described second time of obtaining 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 ' further include:

S14134b ': according to the difference between described second time and the described very first time described One is determined as the described position being pressed in many sub- positions.

In another embodiment, described at least two Doppler measurement information are general more than three Strangle metrical information, described step s141b may include that

S141b ": according to the corresponding first Doppler measurement information of the first test position, the second inspection Location puts corresponding second Doppler measurement information and the 3rd test position is corresponding more than the 3rd general Strangle the position being pressed described in metrical information determination.
