Below with reference to specific embodiment, the function of described step S120, S140 and S160 is described in detail.
S120: one contact action is executed to an object in response to the finger of user, obtains the PPG information of the finger.
Wherein, the finger can be any finger, such as index finger, thumb of user etc..The object can be one
One accessible interface, for example can be display screen, the desktop of any material, the back side of mobile phone, the surface of glass etc..It is described
Contact action can such as be pressing, sliding etc..
The waveform diagram of Fig. 2 collected PPG information when being index finger short-press an object in one embodiment of the application, wherein
Waveform in dashed rectangle is the waveform of corresponding short-press movement, it can be seen that when user's short-press, will lead to the width of PPG waveform
Angle value reduces, and is gradually increasing after being reduced to a trough, declines again again after rising to a typical peak point, then restores to not having
Waveform when pressing.The range value of the typical peak point is substantially equal to the range value of the wave crest of PPG waveform when not pressing.
The waveform diagram of Fig. 3 collected PPG information when being index finger long-pressing an object in one embodiment of the application, wherein
Waveform in dashed rectangle is the waveform of corresponding long-pressing movement, it can be seen that when a user long presses, will lead to the width of PPG waveform
Angle value reduces, and is gradually increasing again after being reduced to a trough, declines again after rising to a sub- peak point, then rises to again next
A Asia peak point declines again, so repeats, until the PPG waveform can rise to a standard when index finger leaves the object
Then peak point restores to waveform when not pressing.The Asia peak point is the wave crest that range value is less than typical peak point.
Fig. 4 is the waveform diagram of index finger collected PPG information when sliding in an object in one embodiment of the application,
Wherein the waveform in dashed rectangle is the waveform of corresponding sliding action, it can be seen that it is described right to start to press before user's sliding
As when, the range value that will lead to PPG waveform reduces, and is gradually increasing again after being reduced to a trough, when rising to a standard valley
When point, with the sliding of index finger, range value is substantially maintained near the standard valley point, is slightly fluctuated, and waveform is without bright
Aobvious regularity, until the PPG waveform can rise to a typical peak point when index finger leaves the object, then restore to
Waveform when not pressing.The range value of the standard valley point is substantially equal to the amplitude of the trough of PPG waveform when not pressing
Value.
It can be seen that the waveform of obtained PPG information has obvious when user executes in above-mentioned different action process
Difference, the application is based on the principle and realizes identification to user action type.

Wherein, whether the first threshold is used to detect the range value of the PPG information and be substantially reduced, can be according to not having
There is the trough range value of PPG waveform when pressing to determine, i.e., the described first threshold is significantly lower than the trough range value, such as will
The trough range value of PPG waveform when not pressing subtracts the amplitude that the peak amplitude value of PPG waveform when not pressing obtains
Value is used as the first threshold.Whether the range value that the second threshold is used to detect the PPG information is bright after being substantially reduced
It is aobvious to rise, it can be determined according to the peak amplitude value of PPG waveform when not pressing, such as by PPG wave when not pressing
The 80% of the peak amplitude value of shape is determined as the second threshold.
It will be appreciated by those skilled in the art that the second threshold should be higher than the first threshold.
In addition, it will be appreciated by those skilled in the art that may be obtained multiple meeting the first of condition according to the first threshold
Point, for example, assuming that the first threshold is th1 in Fig. 2, then the point between available d1 to d2 is all satisfied condition, according to upper
Herein described method can be achieved in any point for stating the condition of satisfaction.But in order to improve the arithmetic speed of the method, simultaneously
Also for the real-time process performance for improving the method, it may further require that be lower than the first threshold at described first point
First sampled point may thereby determine that first sampled point in Fig. 2 below d1 point is at described first point.
More second points for meeting condition may be obtained according to the second threshold, such as in Fig. 2, it is assumed that described
Two threshold values are th2, then available multiple sections: between u1 to u2, between u3 to u4, between u5 to u6 etc., multiple section
Interior point is all satisfied condition, and herein described method may be implemented according to the above-mentioned any point for meeting condition.The step
S140 can select one according to a pre-defined rule from multiple second points for meeting condition in some section.For example, in order to
Simplify the calculation amount of the method and improves real-time process performance, it can be between u1 to u2, the after selecting at described first point
One is higher than the point of the second threshold as the second point, i.e., the described second point is that range value is higher than the second threshold
In at least one point, after described first point and with the smallest point of first point of the time interval.In this case, with
For Fig. 2, it can determine that first sampled point in figure above u1 point is the second point.
It will be appreciated by those skilled in the art that the pre-defined rule be also possible to select u3 to u4 between, between u5 to u6 or
More posteriorly any is equivalent in fact in this case as the second point and moves back several on the basis of afore-mentioned
The PPG period is equivalent to first above u1 point and samples for selecting first sampled point in Fig. 2 above u3 point
1 PPG period is moved back on the basis of point.
S160: according at least to first point of time interval between the second point, the contact action is determined
Type of action.
In the application, the type of action may include short-press and long contact.The compressing time of the short-press can be less than
One predetermined value, such as 1 second；Correspondingly, the time of contact of the long contact can be greater than a predetermined value, such as or 1 second.
In addition, the long contact can be further divided into long-pressing and sliding.
In one embodiment, the step S160 may include:
S161: the type of action of the contact action is determined with reference to being spaced less than one first in response to the time interval
For short-press.
Wherein, described first is a reference time value for distinguishing the contact action type with reference to interval, can be with
It is configured, for example can be set to 1 second according to the use habit of user.For the waveform shown in Fig. 2, it is assumed that pass through and calculate hair
Existing first point of time interval between second point is 0.5 second, is less than described first with reference to being spaced 1 second, so as to judge
The type of action for stating contact action is short-press.
For the sake of simplicity, in the application described first with reference to be with the second point be at interval before point is between u1 to u2
It mentions and being configured.It will be appreciated by those skilled in the art that when select point between u3 to u4, between u5 to u6 or more posteriorly as institute
State second point, described first with reference to interval can by increasing several PPG period to be adjusted, such as, it is assumed that selection Fig. 2
Point between middle u3 to u4 is second point, then described first can be adjusted by increasing by 1 PPG period with reference to interval.This
Field technical staff understands that user carries out in human-computer interaction process by movement, and also frequently using double-clicking, double-click in fact may be used
To be divided into continuous short-press twice.Therefore, in one embodiment, the method can also include:
S170: being short-press in response to the type of action, and another contact action before the contact action is dynamic
Making type is also short-press, determines the second time interval between the contact action and another contact action；
S180: determine whether user performs primary double-click according to second time interval.
Wherein, the type of action of another contact action can be identical according to the type of action of the identification contact action
Mode complete.That is, the method can remember the type of action recognition result in for the previous period, for integrating
Judge current user action.
In the step S180, second time interval can be double-clicked into interval with one and be compared, and then judge to use
Whether the short-press twice at family is continuous action, that is, is double-clicked.The double-click interval can be configured according to the use habit of user,
For example can be set to 0.5 second, to can identify that user holds if second time interval is spaced less than the double-click
Otherwise primary double-click of having gone can identify that user executes short-press twice respectively.
In one embodiment, the step S160 can also include:
S162: it is greater than one second with reference to being spaced in response to the time interval, determines the type of action of the contact action
For long contact.
Wherein, described second can be identical with reference to interval as described first with reference to interval, or described the can also be greater than
One with reference to interval.For the sake of simplicity, second reference interval in the application is also with the second point u1 to the point between u2
Premised on be configured.It will be appreciated by those skilled in the art that when the point between selection u3 to u4, between u5 to u6 or more posteriorly is made

Between PPG waveform, it can be seen that the portion waveshape be mainly wave crest range value reduce, still show apparent week in fact
Phase property rule, periodic regularity and the periodic regularity of PPG information when not pressing have apparent consistency.Inventor grinds
Study carefully discovery, the heart rate value being calculated according to the portion waveshape is in normal heart rate interval, for example, according to v point and p in Fig. 3
The heart rate value that PPG waveshape between point obtains is 89.Meanwhile comparison diagram 4, it can be seen that in Fig. 4 between v point and p point
PPG waveform, peak amplitude value is also obviously reduced, and waveform is mixed and disorderly.Inventor according to the portion waveshape the study found that calculate
The heart rate value arrived is not in normal heart rate interval, for example, being obtained according to the PPG waveshape in Fig. 4 between v point and p point
Heart rate value is 201.Based on the above principles, it is long-pressing or cunning that the method, which can distinguish the type of action of the contact action,
It is dynamic.
