Interpretation of sensor event values in Android devices
The acceleration sensor, also known as G-sensor, returns the acceleration values of the x, y, and z axes.
This value contains the influence of gravity, measured in m/s ^ 2.

instantiation: Creates an instance of a class, the concrete object of the class.
method: a function defined in a class.
object: An instance of a data structure defined by a class. The object consists of two data members (class variables and instance variables) and methods.

it's not easy to really implement it. "Add a touch screen" is very simple, but this is missing the fundamental sense of the return to the simple spirit of innovative interactive design of the spiritual core.

Put the phone flat on the desktop, the X axis defaults to the 0,y axis default 0,z axis default 9.81.
Turn the phone down on the desktop, and the z-axis is-9.81.
Tilt the phone to the left and the x-axis to positive.
Tilt the phone to the right with a negative x-axis.
Tilt the phone up and the Y axis is negative.
Tilt the phone down and the y-axis is positive.
The accelerometer may be the most mature MEMS product, and there are many kinds of accelerometer in the market.
