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, when the finger of user perform such as to press, slip etc. During action, the blood flow signal gathered at this finger position can be caused to produce the change of obvious waveform. Based on this, herein described method can be according to the blood flow information gathered at finger to finger Action relevant information is identified, and then determines corresponding input 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: the finger in response to user performs a contact action to an object, obtains described The blood flow information of finger；

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

S160: according at least to the time interval between described first and described second point, determine One input information.

Method described in the embodiment of the present application, an object execution one is connect by the finger in response to user Touch and make, obtain the blood flow information of described finger, in described blood flow information, determine that range value is high In the first point of first threshold, and range value is less than the second point of Second Threshold, the most at least According to the time interval between described and described second point, determine described input information at first. Thus providing a kind of method determining input information according to blood flow information, described method can be answered With the blood flow transducer in Wearable, and it is effectively increased the interaction capabilities of Wearable.

Below with reference to detailed description of the invention, describe described step S120, S140 and S160 in detail Function.

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

Wherein, described finger can be arbitrary finger of user, such as forefinger, thumb etc..Institute Stating object can be an arbitrary interface contacted, and can be such as display screen, any material Desktop, the back side of mobile phone, the surface etc. of glass.Described contact action can be such as pressing, Slide.Described blood flow information can be BVF (Blood Volume Flow, blood volume Flow) information, it can be obtained by corresponding blood flow transducer, described blood flow transducer ratio A ultrasonic array in this way.

Fig. 2 be in one embodiment of the application forefinger short by an object time BVF that collects The oscillogram of information, wherein the waveform in dashed rectangle is corresponding short by the waveform of action, permissible See, when user is short on time, the range value of BVF waveform can be caused to rise, when rising to one It is gradually reduced again after crest, rises again after dropping to a standard valley point, then recover to not having Waveform during pressing.The BVF when range value of described standard valley point is substantially equal to not press The range value of the trough of waveform.

The BVF that collects when Fig. 3 is that in one embodiment of the application, forefinger length is by an object The oscillogram of information, wherein the waveform in dashed rectangle is corresponding long by the waveform of action, permissible See, when a user long presses, the range value of BVF waveform can be caused to rise, when rising to one It is gradually reduced again after crest, rises again after dropping to a sub-valley point, drop to next the most again Individual sub-valley point rises again, so repeats, during until forefinger leaves described object, and described BVF Waveform can drop to a standard valley point or lower, then recovers to ripple when not pressing Shape.The range value of described sub-valley point is more than the amplitude of the trough of BVF waveform when not pressing Value.

Fig. 4 is that in one embodiment of the application, forefinger collects when sliding on an object The oscillogram of BVF information, wherein the waveform in dashed rectangle is the waveform of corresponding sliding action, It will be seen that when starting to press described object before user slides, BVF waveform can be caused Range value raises, and is gradually reduced again, when dropping to a typical peak point after being increased to a crest Time, along with the slip of forefinger, its range value substantially maintains near described typical peak point, slightly Having fluctuation, its waveform is without evident regularity, during until forefinger leaves described object, and described BVF Waveform can drop to a standard valley point, then recovers to waveform when not pressing.Described The range value of the crest of BVF waveform when the range value of typical peak point is substantially equal to not press.

It will be seen that when user performs in above-mentioned different course of action, obtained BVF The waveform of information has significantly difference, and the application is based on this principle and realizes user action The identification of type.

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

Wherein, described first threshold the most substantially rises for the range value detecting described blood flow information Height, it can determine according to the peak amplitude value of blood flow waveform when not pressing, the most described One threshold value is apparently higher than described peak amplitude value, such as by the ripple of blood flow waveform when not pressing Acrometron angle value increases by 20% as described first threshold.Described Second Threshold is used for detecting described blood Whether the range value of stream information is decreased obviously after significantly raised, and it can be according to when not pressing The trough range value of blood flow waveform determine, such as by the trough of blood flow waveform when not pressing Range value increases by 10% and is defined as described Second Threshold.

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

It addition, it will be appreciated by those skilled in the art that and may obtain multiple according to described first threshold Meet the first point of condition, such as, Fig. 2 assuming, described first threshold is th1, the most permissible The point obtained 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 described method, the most also In order to improve the real-time process performance of described method, may further require that be height at described first In first sampled point of described first threshold, may thereby determine that in Fig. 2 above d1 point First sampled point is described first point.

The more second point meeting condition may be obtained according to described Second Threshold, such as scheme In 2, it is assumed that described Second Threshold is th2, then can obtain multiple interval: 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 described method and improve real-time process performance, permissible Between u1 to u2, select first point less than described Second Threshold after described first As described second point, the most described second point is that range value is less than at least the one of described Second Threshold In individual point, it is positioned at the point that the time interval after described first and with described first is minimum. In this case, as a example by Fig. 2, it may be determined that first sampled point below u1 point in figure For described second point.

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

In one embodiment, described time interval may be used for reflecting described contact action Type of action, the corresponding different time interval of the most different type of action, so that corresponding different Input information.In present embodiment, described step S160 may include that

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

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

In described step S161, described type of action can include short contacting by with long.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, can also be such as 1 second.It addition, described length connects Touch to be further divided into and grow by and slide.

Corresponding pass in described step S162, between described type of action with described input information System can be predetermined, and its corresponding relation can be as shown in table 1.Assume an intelligence ring Communicating with an intelligent glasses, intelligence ring obtains the type of action of user and then controls described intelligence Can glasses, intelligence ring recognize one long by the case of, it can control intelligent glasses and beat Open APP (application) and select menu；In the case of bracelet recognizes a sliding action of user, Intelligent glasses performs a page turn over operation, i.e. shows next APP in its display window；Work as bracelet Recognize user one short by action in the case of, currently displaying APP is selected.Table 1 Shown relation table can be stored in advance in as inside the described intelligence Wearable such as ring, and And such relation table can be given in its operation instructions, in order to instruct and train user to lead to The action executing crossed in similar table 1 orders input accordingly.

In one embodiment, described step S161 may include that

S1611: in response to described time interval less than one first with reference to interval, determine described in connect Touch make type of action be short by.

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

For the sake of Jian Dan, described first in the application is all to be u1 with described second point with reference to interval It is configured premised on point between u2.It will be appreciated by those skilled in the art that when selecting u3 to arrive Point between u4, between u5 to u6 or more posteriorly is as described second point, described first ginseng Examining interval can be by increasing several blood flows cycle to be adjusted, such as, it is assumed that select figure In 2, the point between u3 to u4 is second point, and the most described first can be by increasing with reference to interval 1 blood flow cycle is adjusted.It will be appreciated by those skilled in the art that user is being carried out by action In interactive process, also frequently use double-click, double-click and in fact can be divided into continuous print two Secondary short press.Therefore, in one embodiment, described method can also include:

S170: be short by, and another before described contact action in response to described type of action The type of action of one contact action is also pressed for short, determines that described contact action contacts with described another 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 another contact action described can be according to identifying described contact action The identical mode of type of action complete.During it is to say, described method can remember the last period Interior type of action recognition result, for the user action that comprehensive descision is current.

In described step S180, described second time interval and one can be double-clicked interval and carry out Relatively, so judge short twice of user by whether being continuous action, i.e. 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 interval of double-clicking, then can identify that user performs Once double-click, otherwise, can identify that user performs short twice respectively and presses.

In one embodiment, described step S161 can also include:

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

Wherein, described second with reference to interval can and described first identical, or also with reference to interval Can be more than described first with reference to interval.For the sake of Jian Dan, between described second reference in the application Every being also to be configured premised on the point that described second point is between u1 to u2.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 with reference to interval can also by increase several blood flows cycle with It is adjusted.

Described long contact refers to be more than the contact action at described second reference interval time of contact, than As can be long by or slide.As a example by Fig. 3 and Fig. 4, it can be seen that when user performs When length is pressed or slides, described time interval can be longer than short time interval on time.

In some cases, described method can directly according to the determination result of described step S162, Input the input information that described long contact is corresponding；In other cases, described method is also possible to Need to further discriminate between described length to contact, such as determine whether to grow by or slide.

In one embodiment, described step S161 can also include:

S16121: in response to described time interval more than described second with reference to interval, according to described Blood flow information between first and described second point 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 pressed for long.

As a example by Fig. 3, the blood flow information between described first and described second point can be corresponding Blood flow waveform between v point and p point in Fig. 3, it can be seen that this portion waveshape is mainly ripple The range value at peak reduces, and the most still shows obvious periodic regularity, its periodic regularity With the periodic regularity of blood flow information when not pressing, there is obvious concordance.Inventor studies Find, according to the calculated heart rate value of this portion waveshape in normal heart rate interval, such as, It is 86 according to the calculated heart rate value of blood flow waveform between v point and p point in Fig. 3.With Time, comparison diagram 4, it can be seen that blood flow waveform between v point and p point in Fig. 4, crest Range value is also obviously reduced, and waveform is mixed and disorderly.Inventor studies discovery, according to this subwave The calculated heart rate value of shape is not in normal heart rate interval, such as, according to v point in Fig. 4 With the calculated heart rate value of blood flow waveform between p point is 961.Based on above-mentioned principle, institute It is to grow by or slide that the method for stating can distinguish the type of action of described contact action.

In described step S16121, can calculate according to any one existing blood flow algorithm of heart rate Described heart rate value, such as, can input the blood flow letter between described and described second point at first Breath, utilizes summit to find function and finds out the trough summit of effective blood flow information, and correspondence is the most adjacent Two trough summits calculate the time difference that unit is the second, make the inverse of each time difference take advantage of Using 60 as intermediate object program, all intermediate object programs do and then divided by intermediate object program quantity i.e. 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 is arranged, and the most in most of the cases, i.e. user is static or described in the case of experiencing small oscillating movements 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, determines described The type of action of contact action is for sliding.

In order to describe clear for the sake of, in above-mentioned embodiment, substantially according to the described time between Every determining described type of action, and then determine described input information according to described type of action, also It is exactly according to the first couple between described time interval, described type of action and described input information Should be related to and determine described input information.It will be appreciated by those skilled in the art that and described method is held For row equipment, it need not be concerned about described type of action completely, say, that it can be direct Determine described defeated according to the second corresponding relation between described time interval and described input information Enter information.Certainly, for a user, it is still necessary to understand described first corresponding relation, Will pass through the different types of action of execution, control the input information that input is different.

In another embodiment, described time interval may be used for reflecting described contact action Duration, the corresponding different time interval of the most different duration, and then corresponding different input letter Breath.In present embodiment, described step S160 may include that

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

S162 ': determine the described input information that described duration is corresponding.

Described step S161 ' in, described second point can be that range value is less than described Second Threshold At least one point in, be positioned at the described time interval after first and with described first Little point.In such a case, it is possible to directly determine that the duration of described contact action is equal to described Time interval.

Being similar to an 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 at described contact action in fact Duration on the basis of add several blood flows cycle, therefore, as long as described obtained Time interval a little and between described second point deducts the blood flow cycle of respective numbers can be really The duration of fixed described contact action, such as assumes that described second point takes in Fig. 2 between u3 to u4 Point, then can deduct 1 blood flow by the time interval between described and described second point at first 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 was less than 1 second, a control command is inputted； When described duration was 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, namely root according to described duration Determine according to the 3rd corresponding relation between described time interval, described duration and described input information Described input information.It will be appreciated by those skilled in the art that for the execution equipment of described method, It can be concerned about described duration completely, say, that it can be directly according to the described time The 4th corresponding relation between interval and described input information determines described input information.Of course, For a user, it is still necessary to understand described 3rd corresponding relation, in order to by input The action of different durations, controls the input information that input is different.

It addition, in actual applications, described duration can also combine with type of action, with group Close out more input information.Such as, as a example by sliding, when slip duration is more than within 1 second, being less than When 1.5 seconds, page 1 order is turned in input；When slip duration was more than 1.5 seconds, page 2 are turned in input Order.

Additionally, the embodiment of the present application also provides for a kind of computer-readable medium, it is included in and is performed The computer-readable instruction of below Shi Jinhang operation: perform in above-mentioned Fig. 1 illustrated embodiment Step S120 of method, the operation of S140 and S160.
