HI 你好，请问个Android计步算法的问题
为什么你要用手写的方式进行滤波，而不是用傅里叶变换的方式进行滤波呢？
gravityNew = (float) Math.sqrt(oriValues[0] * oriValues[0] + oriValues[1] * oriValues[1] + oriValues[2] * oriValues[2]);
gravityNew = (float) Math.sqrt(oriValues[0] * oriValues[0]
+ oriValues[1] * oriValues[1] + oriValues[2] * oriValues[2]);
这个代表传感器的值啊
传感器初始值采用平方相加 再开根号的方式
如果本身传感器的值是带负值的，这样平方相加再开根号后，全部变成了正值，本文所采用的方法应当将步数/2，这样才对吧？
请教一些为什么计步超时时候记录值为1而不是清空为0呢？这样噪声不是很大吗？
有没有iOS的例子呢？
不知道iOS是不是重力感应传感器。
计步清零
大神你好：
计步的时候有些时候会清零，请问你遇到过吗
Sensor.TYPE_STEP_COUNTER 这个传感器需不需要app保活？
梯度化阈值的作用
你好，我想请问一下梯度化阈值的作用是什么？为什么要这么做？
请问能不能监测是否是倒着走还是往前走？
现在不管是倒着走还是往前走都会计数。
