Thus providing one kind to determine input information method according to ppg information, methods described can be answered With the ppg sensor in Wearable, the interactive energy of Wearable can be effectively improved Power.

Below with reference to specific embodiment, describe described step s120, s140 and s160 in detail Function.

S120: the finger in response to user executes a contact action to an object, obtains described The ppg information of finger.

Wherein, described finger can be arbitrary finger of user, such as forefinger, thumb etc..Institute Stating object can be an arbitrary accessible interface, can be such as display screen, any material Desktop, the back side of mobile phone, the surface of glass etc..Described contact action can be such as pressing, Slide etc..

Fig. 2 be in one embodiment of the application forefinger short by an object when collect ppg letter The oscillogram of breath, the wherein waveform in dashed rectangle are the corresponding short waveforms by action, can see Arrive, when user is short on time, the range value of ppg waveform can be led to reduce, when being reduced to a ripple It is gradually increasing after paddy again, declines after rising to a typical peak point again, then recover to not pressing Waveform during pressure.The range value of described typical peak point is substantially equal to ppg ripple when not pressing The range value of the crest of shape.

Fig. 3 be in one embodiment of the application forefinger length by an object when collect ppg letter The oscillogram of breath, the wherein waveform in dashed rectangle are the corresponding long waveforms by action, can see Arrive, when a user long presses, the range value of ppg waveform can be led to reduce, when being reduced to a ripple It is gradually increasing after paddy again, decline after rising to a sub- peak point again, then rise to the next one again Sub- peak point declines again, so repeats, until when forefinger leaves described object, described ppg Waveform can rise to a typical peak point, then recovers to waveform when not pressing.Described Sub- peak point is the crest that range value is less than typical peak point.

Fig. 4 is that in one embodiment of the application, forefinger collects when sliding on an object Waveform in the oscillogram of ppg information, wherein dashed rectangle is the waveform of corresponding sliding action, Can see, when starting to press described object before user slides, ppg waveform can be led to Range value reduces, and is gradually increasing after being reduced to a trough again, when rising to a standard valley point When, with the slip of forefinger, its range value substantially maintains near described standard valley point, slightly There is fluctuation, its waveform no evident regularity, until when forefinger leaves described object, described ppg Waveform can rise to a typical peak point, then recovers to waveform when not pressing.Described The range value of standard valley point is substantially equal to the range value of the trough of ppg waveform when not pressing.

Can see, when user executes in above-mentioned different course of action, obtained ppg believes The waveform of breath has obvious difference, and the application is based on this principle and realizes to user action class The identification of type.

S140: determine that range value is less than first point of first threshold in described ppg information, with And range value is higher than the second point of Second Threshold.

Wherein, described first threshold is used for detecting whether the range value of described ppg information substantially drops Low, it can determine according to the trough range value of ppg waveform when not pressing, that is, described First threshold is significantly lower than described trough range value, such as by ppg waveform when not pressing Trough range value deduct the amplitude that the peak amplitude of ppg waveform when not pressing is worth to Value is as described first threshold.Described Second Threshold is used for detecting the amplitude of described ppg information Whether value substantially rises after obvious reduction, and it can be according to ppg waveform when not pressing Peak amplitude value determine, such as by the peak amplitude value of ppg waveform when not pressing 80% is defined as described Second Threshold.

It will be appreciated by those skilled in the art that described Second Threshold should be higher than described first threshold.

In addition, it will be appreciated by those skilled in the art that may be obtained multiple according to described first threshold Meet at first point of condition, such as, in Fig. 2, assume that described first threshold is th1, then permissible The point obtaining between d1 to d2 is satisfied by condition, according to the above-mentioned any point meeting condition Realize herein described method.But, in order to improve the arithmetic speed of methods described, simultaneously In order to improve the real-time processing performance of methods described, may further require that be low at described first point In first sampled point of described first threshold, may thereby determine that below d1 point in Fig. 2 First sampled point is at described first point.

The second point that more meet condition may be obtained according to described Second Threshold, such as scheme It is assumed that described Second Threshold is th2 in 2, then can obtain multiple intervals: between u1 to u2, Between u3 to u4, between u5 to u6 etc., the point in the plurality of interval is satisfied by condition, root Herein described method all can be realized according to the above-mentioned any point meeting condition.Described step s140 Can select from multiple second points meeting condition in some interval according to a pre-defined rule One.Such as, in order to simplify the amount of calculation of methods described and improve real-time processing performance, permissible Between u1 to u2, first point higher than described Second Threshold after selecting at described first point As described second point, that is, described second point is at least that range value is higher than described Second Threshold In individual point, after described first point and the point minimum with described first point of time interval. In this case, first sampled point it may be determined that above in figure u1 point taking Fig. 2 as a example For described second point.

It will be appreciated by those skilled in the art that described pre-defined rule can also be select u3 to u4 between, Between u5 to u6 or more posteriorly a little as described second point, in this case, in fact Be equivalent to and move several ppg cycles after on the basis of afore-mentioned, to select u3 in Fig. 2 As a example first sampled point of point top, it is equivalent to first sampled point above u1 point On the basis of after move 1 ppg cycle.

In one embodiment, described time interval can be used for reflecting described contact action Type of action, the different time interval of that is, different type of action correspondences, and then correspondence is different Input information.In present embodiment, described step s160 may include that

S161: according at least to described first point of time interval and described second point between, determine The type of action of described contact action；

S162: determine the corresponding described input information of described type of action.

In described step s161, described type of action can include short by with length contact.Described The short compressing time pressed can be less than a predetermined value, such as 1 second；Accordingly, described long contact Time of contact can be more than a predetermined value, such as can also be 1 second.In addition, described length connects Touch to be further divided into and grow by and slide.

In one embodiment, described step s161 may further include:

S1611: be less than one first reference interval in response to described time interval, connect described in determination Touching the type of action made is short pressing.

Wherein, described first reference interval is the reference for distinguishing described contact action type Time value, it can be configured according to the use habit of user, such as could be arranged to 1 second. It is assumed that finding first point of time and second point between by calculating taking waveform shown in Fig. 2 as a example It is spaced apart 0.5 second, less than described first reference interval 1 second, such that it is able to judge described contact The type of action of action is short pressing.

For the sake of simple, described first reference interval in the application is all to be u1 with described second point It is configured premised on putting between u2.It will be appreciated by those skilled in the art that when selection u3 arrives Point between u4, between u5 to u6 or more posteriorly is as described second point, described first ginseng Examine interval to be adjusted by increasing several ppg cycles, such as it is assumed that selecting In Fig. 2, the point between u3 to u4 is second point, then described first reference interval can be by increasing Plus 1 ppg cycle is adjusted.It will be appreciated by those skilled in the art that user is by action Carry out in interactive process, also frequently using double-click, double-click and in fact can be divided into continuously Short twice press.Therefore, in one embodiment, methods described can also include:

S170: press for short in response to described type of action, and another before described contact action The type of action of one contact action be also short press, determine that described contact action another contacts with described The second time interval between action；

S180: determine whether user performs according to described second time interval and once double-click.

Wherein, the type of action of described another contact action can be according to the described contact action of identification Type of action identical mode complete.That is, when methods described can remember the last period Interior type of action recognition result, for the current user action of comprehensive descision.

In described step s180, described second time interval can be carried out with a double-click interval Relatively, so judge user short twice by whether being continuous action, that is, double-click.Described double-click Interval can be configured according to the use habit of user, such as could be arranged to 0.5 second, from And if described second time interval is less than described double-click and is spaced, then can be performed with identifying user Once double-click, otherwise, short twice pressing can be executed respectively with identifying user.

In one embodiment, described step s161 can also include:

S1612: be more than one second reference interval in response to described time interval, connect described in determination Touching the type of action made is long contact.

Wherein, described second reference interval can be identical with described first reference interval, or Described first reference interval can be more than.For the sake of simple, between described second reference in the application Every be also be between u1 to u2 by described second point point premised on be configured.This area skill Art personnel understand, make when selecting point between u3 to u4, between u5 to u6 or more posteriorly For described second point, described second reference interval can also be by increasing several ppg cycles To be adjusted.

Described long contact refers to be more than the contact action of described second reference interval time of contact, than As can be long by or slide.Taking Fig. 3 and Fig. 4 as a example it can be seen that working as user's execution When length is pressed or slided, described time interval can be significantly long than short time interval on time.

In some cases, the determination result that methods described can directly according to described step s1612, The input corresponding input information of described long contact；In other cases, methods described is also possible to Need to further discriminate between described long contact, such as determine whether to grow by or slide.

In one embodiment, described step s161 can also include:

S16121: be more than described second reference interval in response to described time interval, according to described First point of ppg information and described second point between determines a heart rate value；

S16122: belong to a target heart rate scope in response to described heart rate value, determine described contact The type of action of action is that length is pressed.

, the described first point ppg information and described second point between can correspond to taking Fig. 3 as a example In Fig. 3, the ppg waveform between v point and p point is it can be seen that this portion waveshape is mainly The range value of crest reduces, and in fact still shows obvious periodic regularity, and it is periodically advised Rule has obvious concordance with the periodic regularity of ppg information when not pressing.Inventor Research finds, according to the calculated heart rate value of this portion waveshape in normal heart rate interval, Such as, according to the heart rate value that the ppg waveshape between v point and p point in Fig. 3 obtains it is 89.Meanwhile, contrast Fig. 4 is it can be seen that the ppg waveform between v point and p point in Fig. 4, Peak amplitude value is also obviously reduced, and waveform is mixed and disorderly.Inventor's research finds, according to this portion The calculated heart rate value of partial wave shape not in normal heart rate interval, such as, according in Fig. 4 The heart rate value that ppg waveshape between v point and p point obtains is 201.Based on above-mentioned principle, The type of action that methods described can distinguish described contact action is to grow by or slide.

In described step s16121, can be calculated according to any one existing ppg algorithm of heart rate Described heart rate value, such as, can input described first point of ppg and described second point between Information, finds, using summit, the crest summit that function finds out effective ppg information, then counts The unit calculating adjacent vertex is the time difference of second, and the inverse obtaining difference afterwards is multiplied by 60 The heart rate value of user can be drawn.

In described step s16122, described target heart rate scope can be entered according to the state of user Row setting, such as in most of the cases, that is, user is static or experiencing small oscillating movements in the case of described Target heart rate may range from 60-100 beat/min；And after user strenuous exercise, such as run After step, described target heart rate may range from 100-180 beat/min.

In another embodiment, described step s161 can also include:

S16123: be not belonging to described target heart rate scope in response to described heart rate value, determine described The type of action of contact action is to slide.

In another embodiment, described time interval can be used for reflecting described contact action Duration, the different time intervals of that is, different duration correspondences, and then the different inputs letter of correspondence Breath.In present embodiment, described step s160 may include that

S161 ': according at least to described first point of time interval and described second point between, determine The duration of described contact action；

S162 ': determine the corresponding input information of described duration.

Described step s161 ' in, if described second point is range value is higher than described Second Threshold At least one point in, after described first point and with described first point of time interval Little point.In such a case, it is possible to directly determine the duration of described contact action equal to described Time interval.

Similar to a upper embodiment, described second point can also be such as u3 to u4 in Fig. 2 Between or u5 to u6 between point, when taking these, be in described contact action in fact Duration on the basis of increased several ppg cycle, therefore, as long as described in obtain First point of time interval and described second point between deducts the ppg cycle of respective numbers Determine the duration of described contact action, such as assume described second point take in Fig. 2 u3 to u4 it Between point, then described first point of time interval and described second point between can be deducted 1 The ppg cycle, to determine the duration of described contact action.

Described step s162 ' in, the corresponding relation between described duration and described input information can To be predetermined, such as, when described duration is less than 1 second, input a control command； When described duration is more than 1 second, input another control command.

Clearer in order to describe, in above-mentioned embodiment, substantially according to the described time Interval determines described duration, and then determines described input information according to described duration, that is, institute State and there is between time interval, described duration and described input information one the 3rd corresponding relation.This Skilled person understands, for the execution equipment of methods described, it completely may not necessarily It is concerned about described duration that is to say, that it can be directly according to described time interval and described input The 4th corresponding relation between information determines described input information.Of course, for a user, It is still necessary understanding described 3rd corresponding relation, will pass through the action of the different duration of input, The different input information of control input.

In addition, in actual applications, described duration can also be combined with type of action, with group Close out more input informations.Such as, taking slide as a example, when slip duration was less than more than 1 second When 1.5 seconds, page 1 order is turned in input；When slip duration is more than 1.5 seconds, page 2 are turned in input Order.

Additionally, the embodiment of the present application also provides a kind of computer-readable medium, including being performed The computer-readable instruction of below Shi Jinhang operation: execute in above-mentioned Fig. 1 illustrated embodiment Step s120, s140 of method and the operation of s160.
