如何使用计步器计算脚踏 [英] How to calculate Foot step using Pedometer
问题描述
我开发应用的卡路里计算由步行烧我使用SensorEventListener （加速度计）我从那个X，Y，Z三个值。
我的问题是如何使用三个X，Y，Z计算踏上一步。
这是我的code为获得X，Y，Z值。我使用GPS也。但我需要使用Android的计步器计数步 guyzz PLZ帮我。

我的建议是你应该跟踪全球Z轴的变化（你的身体向上/向下运动）。你不能机制保障用户将持有的中移动一个特定的方向，因此您将不得不依赖于实验。此外，您可能需要监控移动的速度（以免转化汽车运动，脚步骤例如）。
我会做的是：
1 - 创建上移动一个文本文件，并记录X，Y和放大器的价值; Z（除GPS速度），而我走，在不同的方向移动（在我的口袋里，在一个腰包，...等）。另外，保持的我执行的步骤的数量的轨道。
-2-基于该数据，在步骤之一，形成一个公式来将此数据转换为的脚步数。
i develop application for calculation of calories burn by walking for that i use SensorEventListener (ACCELEROMETER) i get three value from that X,Y,Z. my question is how to calculate foot step using that three X,Y,Z. this is my code for getting X,Y,Z value. i use GPS also. but i required count step using Pedometer in Android guyzz PLZ help me.

My suggestion is that you should track variations in Global Z axis (your body up/down movement). You cannot guarentee that the user will hold the mobile in a specific orientation, so you will have to rely on experimenting. Also, you may need to monitor the speed of movement (so as not to translate car movement to foot steps for e.g.).
What I would do is:
1- Create a text file on the Mobile and record the values of X, Y & Z (in addition to GPS speed) while I am walking, with the mobile in different orientations (in my pocket, in a belt pouch, ...etc). Also, keep track of the number of steps I performed.
2- Based on this data in step one, form a formula to convert this data to number of foot steps.
