Step:
S111: the skin power information of acquisition user in real time；
S112: the heart rate information of acquisition user in real time.
Wherein, step S111 is specifically included: the skin of user directly and is incessantly contacted by metal electrode, acquisition is used
The skin electric signal at family, wherein the metal electrode is located in the VR/AR equipment.Specifically, skin potential activity (EDA) refers to
Situations such as behavior that the skin resistance of human body, conductance change with the variation of sweat gland of skin function, nervous, fear, excitement, anxiety

S1211: determining the wave crest of skin electric signal, and is pre-processed to crest value to obtain skin electric signal relevance；
S1212: pretreated skin electric signal is converted to the excitement levels index for representing user's excitement levels.
In step S1111, it is possible, firstly, to determine the crest value of skin electric signal with the following method: successively traversal is obtained
The data taken constantly update maximum value, more much smaller than maximum value until there are data, that is, are less than wave crest judgment threshold, sentence at this time
Fixed previous maximum value is wave crest.Other methods can also be used and determine crest value, the judgment method of wave crest is the common of this field
Technology, details are not described herein.
Later, crest value is pre-processed by formula (1) to obtain skin electric signal relevance,
Wherein, VmaxFor the skin electrical signal wave peak value after pretreatment, Vmax-tFor the skin electrical signal wave peak value actually obtained,
VrefFor reference voltage, k is with reference to coefficient.Carrying out pretreated purpose to skin electrical signal wave peak value is to change skin electric signal wave crest
The fluctuation range of value can be preferably quantized.For different acquisition systems, the processing parameter in above-mentioned formula has
Different values, in the present embodiment, the VrefValue be 1900mV, k 4 so that treated crest value fall into [0,
100] in value range, convenient for the quantization and processing in subsequent process.
In step S1112, pretreated skin electric signal is converted to the step for representing the excitement levels index of user's excitement levels

Wherein, X1T, X2T, X3TRespectively failing edge slope threshold value, waveform length threshold value and waveform height threshold value.
If being unsatisfactory for above-mentioned condition, it is gentle to illustrate that the wave crest of corresponding skin electric signal rises and falls, pace of change is relatively low,
The changes of the mood of corresponding user at this time is gentle, no big ups and downs, i.e. user's excitement levels is lower.Set the excitement levels of user at this time
For basic excitement levels YT。
If meeting above-mentioned condition, illustrate that the wave crest of corresponding skin electric signal rises and falls acutely, pace of change is relatively fast, right
The changes of the mood of the user at this time answered is big, and acutely, i.e. user's excitement levels is higher, and user's excitement levels at this time is for fluctuationWherein, X1=K1-X1T,

In, since the average excitement levels of user in gaming is in higher level, a relatively high basic excitement levels can be set
YT, such as 85；And in the VR/AR scene of certain intelligence development theme, the average excitement levels of user is relatively low, can set a phase
To lower basic excitement levels YT, such as 70.Different calculating parameters is set in conjunction with different application scenarios, can make excitement levels amount
It is more accurate to change result.
It preferably,, can when going out user there are apparent mood swing by skin electrical signal detection for some special circumstances
It does not need to convert and directly determines that user is in excitatory state, is quantified as a higher value for the excitement levels of user at this time.Example
Such as, when the crest value for detecting conversion is greater than big wave threshold value, then directly judgement user is in excitatory state, the excitement of user at this time
Value Y=YTH, wherein the big wave threshold value is equal to 90%, Y of wave crest maximum valueTHFor the corresponding excitement levels of big wave threshold value, usually
For basic excitement levels YT1.2~1.5 times.In the present embodiment, it is the wave crest of [0,100] for value range, works as pretreatment
Crest value later is greater than 90, that is, can determine whether that user is in excitatory state, and the excitement levels Y of user is 1.5Y at this timeT.In addition, working as
It detects that continuous wave crest occurs in the skin electric signal of user, can also directly judge, directly determine that user is in excitatory state, this
When user excited value Y=YTH.Such direct judgement can be omitted conversion process, saves quantization time, improves system effectiveness.
Later, it handles and calculates for the skin power information of user, include the following steps:
S1221: the heart rate difference DELTA Z of user in Fixed Time Interval is calculated；
S1221: supplement correction is carried out according to excitement levels Y of the heart rate difference to user.
In step S1211, the heart rate difference DELTA Z for calculating user in Fixed Time Interval is specifically included: according to formula (2)
The heart rate difference DELTA Z of user in Fixed Time Interval is calculated,
Wherein, Z0The heart rate value at family, Z are started with for Fixed Time IntervalnUser at the end of for same amount of time interval
Heart rate value, n are the rate calculation factor, Z0And ZnIt is obtained in real time by the second collector, n is configured according to actual needs, is being turned
In the case that the crest value value changed is [0,100], the preferred value of n is 10.
Specifically, carrying out supplement correction according to excitement levels Y of the heart rate difference to user in step S1212, correct
Excitement levels Y afterwards*For
Under normal conditions, the heart rate situation of user is a stable numerical value, when the mood and focus of user change
When change, it will lead to heart rate value and change, by calculating the heart rate difference of user, can further judge the emotional change of user
State avoids error to be corrected to the excited angle value obtained by skin electric signal.
