As z, < when 0, mobile device screen is down.
This method can calculate the change of x, y and z the moment, when one of coordinate changes, represents mobile device
State changes, pre-recorded before present invention execution on once the second three-dimensional coordinate of state change and with once shape
State change the second time, when the state of mobile device changes again, record now the first three-dimensional coordinate of mobile device and
The current very first time.
In order to the process of the clear explanation present invention is with the first three-dimensional coordinate for (x1, y1, z1), very first time t1, the two or three
Dimension coordinate is (x2, y2, z2), and the second time was t2, calculated speed speed of current mobile device, speed=abs (x2+y2+
Z2-x1-y1-z1)/(t2-t1), as t2-t1 > 100ms and speed > 0.02 when, to displacement add up 1m.If t2-t1 >
100ms or speed > 0.02 is false, then the displacement of explanation mobile device is not changed in.
Preferably, typically adopt speed=abs (x2+y2+z2-x1-y1-z1)/(t2-t1) * in a practical situation
10000 calculating the speed of mobile device, as t2-t1 > 100ms and speed > 200 when, displacement is added up 1m.
