1. Like other bluetooth devices, a connection needs to be established to enable the device and the application to receive data from each other, the application written by java can directly call sdk (software development kit) of a bracelet manufacturer to realize connection of the bracelet and reception of the data, and for the application written by c + +, sdk of the java layer needs to be called in the c + + layer.
As shown in fig. 3, jni encapsulates interface functions of Java and other languages for communication, and can enable c + + to invoke the Java function through jni, invoke sdk of a bracelet manufacturer at a c + + layer, and enable a c + + application program to establish communication with a bluetooth device.
An interface function is written in both the c + + layer and the Android java layer, and the c + + layer and the java layer can transmit data to each other through the interface and the jni.
2. After the application program establishes communication with the Bluetooth device, the device will transmit data to the application
The Bluetooth device comprises an acceleration sensor, acceleration in 3 directions of an x axis, a y axis and a z axis which is instantly transmitted by the device is received on a java layer, data is transmitted to a c + + layer, and calculation is carried out on the c + + layer, wherein the calculation principle is as follows:
place bracelet level at the horizontal plane, its initial condition is as shown in figure 1:
the acceleration of each axis at this time is
x＝0
y＝0
z＝1g
When the x-axis is tilted by an angle of alpha, as shown in FIG. 2
The acceleration of each axis at this time is
x' ═ 1g x sin alpha 1 formula
y'＝0
z' ═ 1g Xcos alpha 2 formula
Dividing formula 1 by formula 2 to yield:
wherein
Similarly, if the y-axis deflection angle is set as beta
Then
The positive and negative of the z-axis represent the positive and negative directions of the bracelet.
3. If the instant transmission and the instant processing of data are to be realized, functions which are more than 50 frames per second and are called by each frame need to be set in the application, the higher the frame number is, the smaller the delay is, the different Bluetooth devices have different data transmission amounts per second, and if the data transmission amounts can reach more than 50 times per second, the game can be operated smoothly. The calculated alpha and beta can receive the inclined angle instantly by inclining the x axis and the y axis of the bracelet, and the game operation can be realized by utilizing the two values.
The existing step recording function and sleep monitoring only depend on the vibration of a bracelet to record data, and data transmitted by three axes of a gravity sensor of the existing step recording function and sleep monitoring are fully applied and converted into deflection angles through an algorithm, so that various operations can be carried out through the deflection bracelet.
Take an airplane game as an example:
and changing the position of the airplane according to the deflection angles of the x axis and the y axis so as to achieve the effect of controlling the airplane.
The bracelet that deflects, the bracelet will respond to immediately, and do not transmit our recreation to data with the rate of 60 times per second, and the data that our recreation was taken is exactly the value of the angle of deflection and the z of the x axle that has calculated and y axle, for better bracelet operation experience, the operation of anti-back is taken to accessible code shielding bracelet, if z is the negative value promptly, will not have the transmission of data again. Setting the operation range, when the x-axis deflects to the left by 15-40 degrees, the airplane moves to the left at a slower speed, and when the airplane deflects to the left by 40-90 degrees, the airplane moves to the left at a faster speed and deflects to the right in the same way. The y axis is the up and down movement of the airplane, and the operation mode is the same as the x axis.
This allows for accurate control of the game content or faster targeting with the hand ring.
