Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
In the description of the invention, it is to be understood that term " longitudinal direction ", " transverse direction ", " on ", " under ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, it is for only for ease of the description present invention and simplifies description, rather than instruction or the dress for implying meaning
Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limit of the invention
System.
In the description of the invention, unless otherwise prescribed with limit, it is necessary to explanation, term " installation ", " connected ",
" connection " should be interpreted broadly, for example, it may be mechanical connection or electrical connection or the connection of two element internals, can
To be to be joined directly together, can also be indirectly connected by intermediary, for the ordinary skill in the art, can basis
Concrete condition understands the concrete meaning of above-mentioned term.
1., it is necessary to establish connection equipment and application could be allowed mutually to receive data with as other bluetooth equipments, java is used
The sdk (software development kit) that the application program write can directly invoke bracelet manufacturer can be achieved with the connection of bracelet and connecing for data
Receive, for the application write with c++, it is necessary to call the sdk of java layers in c++ layers.
As shown in figure 3, jni encapsulates Java and the interface function of the communication of other language, c++ can be allowed to adjust by jni
With java function, the sdk of bracelet manufacturer is called in c++ layers, c++ application program can be allowed to be established with bluetooth equipment and communicated.
All write an interface function in the java layers of c++ layers and Android, by this interface and jni can allow c++ and
Java mutual data transmissions.
After 2. application program establishes communication with bluetooth equipment, equipment will be to application transport data
Acceleration sensor is included in our bluetooth equipment, the x of equipment instantaneous transmission, y, z-axis 3 are received in java layers
The acceleration in direction, data are being transferred to c++ layers, calculated in c++ layers, Computing Principle is as follows：
Bracelet is lain in a horizontal plane in into horizontal plane, its original state such as Fig. 1：
The acceleration of each axle now is
X=0
Y=0
Z=1g
When x-axis tilt alpha degree angle, as shown in Figure 2
The acceleration of each axle now is
The formulas of x'=-1g × sin α 1
Y'=0
The formulas of z'=1g × cos α 2
Obtained with 1 formula divided by 2 formulas：
Wherein
Similarly if setting y-axis deflection angle as β
Then
The both forward and reverse directions of the positive negative indication bracelet of z-axis.
3. if to realize the instantaneous transmission and processing immediately of data, need to set in the application more than 50 frame per second and each
The function that frame all calls, frame number get over that high latency is smaller, and the data volume of different bluetooth equipments transmission per second is different, if can reach
More than 50 times per second, operation that just can be smooth is played.The x-axis and y-axis of bracelet are tilted, good α and β can just receive inclination immediately
Angle, the operation of game can be realized using the two values.
Existing note step function and sleep monitor are only that armrest ring is shaken to carry out data record, and we fully apply
The data of its axle of gravity sensor three transmission, and deflection angle is converted into by algorithm, so as to be entered by deflecting bracelet
The various operations of row.
So that aircraft is played as an example：
According to the deflection angle of x-axis and y-axis, change the position of aircraft, to reach the effect of control aircraft.
Bracelet is deflected, bracelet gives instant sensing , And to our game data with the speed rates of 60 times per second, we
The data taken of game be exactly good x-axis and the deflection angle of y-axis and z value, for more preferable bracelet operating body
Test, bracelet can be shielded by code and take anti-operation, even z is negative value, there will not be the transmission of data again.Operation model is set
Enclose, when x-axis deflects between 15 degree to 40 degree to the left, aircraft will be moved with slower speed to the left, when aircraft deflects 40 to the left
Spend to 90 degree, aircraft will be moved with fast speed to the left, be deflected to the right similarly.Y-axis is to operate moving up and down for aircraft, operation side
The same x-axis of formula.
Thus with bracelet game content can accurately be controlled or faster position target.
Which can be used for using for mouse pointer or other movement class game.

The plane of friendship,
After being adjusted, integration of the acceleration magnitude on the time after after being corrected and adjustment；To these acceleration
Value carries out on the integration of time to obtain velocity amplitude, and carries out the further integration on the time to these velocity amplitudes,
To obtain the shift value along two normal axis of plane；
The direction of motion is estimated according to the ratio of the shift value.
7. the analysis according to claim 6 that human body behavior judgement is carried out by inertial sensor matches method of work, its
It is characterised by, the S3 also includes：
Closed based on the acceleration magnitude after inputting and correct relative to the relevant user of the placement of user's body with gravity sensor
In the integration of time, to evaluate the shift value along two normal axis of plane；According to gravity sensor relative to user's body
Placement, be used for by+1/-1 adjust acceleration magnitude the step of, along user movement axle, if gravity sensor is positioned over
The upper part of the body of user, then acceleration magnitude is adjusted -1, and if gravity sensor is positioned over the lower part of the body, then adjusted acceleration magnitude
Whole+1.
8. the analysis according to claim 1 that human body behavior judgement is carried out by inertial sensor matches method of work, its
It is characterised by, in addition to：
Gravity sensor opereating specification is set, and when gravity sensor x-axis deflects between 15 degree to 40 degree to the left, ancillary equipment is grasped
Control object will be moved with slower speed to the left, and when gravity sensor deflects at 40 degree to 90 degree to the left, ancillary equipment manipulates object
It will be moved to the left with fast speed；
When gravity sensor x-axis is deflected to the right between 15 degree to 40 degree, ancillary equipment manipulation object will be to the right with slower speed
Mobile, when gravity sensor is deflected to the right at 40 degree to 90 degree, ancillary equipment manipulation object will be moved to the right with fast speed.
9. the analysis according to claim 1 that human body behavior judgement is carried out by inertial sensor matches method of work, its
It is characterised by, in addition to：
Y-axis moves up and down for operation ancillary equipment, the same x-axis of mode of operation；
If z is negative value, there will not be the transmission of data.
