Below in conjunction with drawings and Examples, the embodiment of the application is described in further detail.Following examples for illustration of the application, but are not used for limiting the scope of the application.
Those skilled in the art understand, in the embodiment of the application, the size of the sequence number of following each step does not also mean that the priority of execution sequence, and the execution sequence of each step should be determined with its function and internal logic, and should not form any restriction to the implementation process of the embodiment of the present application.
Fig. 1 is the process flow diagram of leading limbs defining method described in the application's embodiment, and described method can realize on such as one leading limbs determination equipment.As shown in Figure 1, described method comprises:
S120: PPG (PhotoPlethysmoGraphy) information obtaining first limbs of user;
S140: according to a described PPG information and a reference information, determines whether described first limbs are leading limbs.
Method described in the embodiment of the present application, obtain a PPG information of limbs of user, and then determine whether described first limbs are leading limbs according to a described PPG information and a reference information, thus provide a kind of leading limbs defining method, the Wearable device being conducive to user carries out Lookup protocol according to determination result, promotes Consumer's Experience.
Below with reference to embodiment, describe the function of described step S120 and S140 in detail.
S120: the PPG information obtaining first limbs of user.
Wherein, described first limbs can be hands in two hands of described user, or can be user two arms in an arm, an or pin in user's two pin, or the one leg in the two legs of user.For the purpose of simple, be that a hand in two hands of described user is that example is described below mainly with described first limbs.
Described PPG information can be the PPG signal of a period of time, its can by with user's skin mutually near or at least one PPG sensor of contacting obtain.PPG signal is light by the mode of transmission or reflection through human vas, and the reflection arteries obtained by photodetector is beaten the voltage change signal of the blood volume change caused.The PPG information that namely a described PPG information obtain on described first limbs.
S140: according to a described PPG information and a reference information, determines whether described first limbs are leading limbs.
Inventor finds under study for action, because the leading limbs of people are more sturdy than non-dominant limbs, and pachylosis, skin surface is thicker, cause the skin transmittance of the skin transmittance of non-dominant limbs such as leading limbs low, and then cause the range value of the PPG information gathered on non-dominant limbs can higher than the range value of the PPG information gathered on leading limbs.
Fig. 2 is the contrast schematic diagram of the leading hand of user and the PPG signal of non-dominant hand, abscissa representing time, and ordinate represents the range value of PPG signal, and solid-line curve represents the PPG signal curve of leading hand, and dashed curve represents the PPG signal curve of non-dominant hand.Can see, the range value of the PPG signal of non-dominant hand generally all can higher than the range value of the PPG signal of leading hand.Wherein, the range value of the application is the amplitude of the corresponding waveform of PPG signal, and its value is nonnegative value.
Inventor also finds, the PPG signal of other limbs (as arm, pin, leg) of user, also exists difference similar to Figure 2.Based on above-mentioned principle, the determination to leading limbs can be realized.

S141 ': the averaged amplitude value in response to a described PPG information is greater than described threshold value, determines that described first limbs are not leading limbs;
S142 ': the averaged amplitude value in response to a described PPG information is less than described threshold value, determines that described first limbs are leading limbs.
Such as, gather the right limb PPG information of described user and left limb PPG information in advance, and carry out analyzing and processing, suppose that the averaged amplitude value of described right limb PPG information falls into the first interval (R
pmin, R
pmax), suppose that the averaged amplitude value of described left limb PPG information falls into the second interval (L

p, then think that it falls into described first interval, described first limbs are not the leading limbs of described user; If the averaged amplitude value of a described PPG information is less than described threshold value M
p, then think that it falls into described second interval, described first limbs are leading limbs of described user.
General, the averaged amplitude value of the PPG information of non-dominant limbs can be higher by more than 5% than the averaged amplitude value of the PPG information of leading limbs, can rationally arrange described threshold value M accordingly
p.
