tilt-sensor

I'm trying to get the tilt angle, roll angle from my sensors from my android phone but with no success so far, when I click on my button which should give me the 3 angles, I get "results: 0.0 -0.0 -0.0" package com.example; import android.app.Activity; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.hardware.SensorManager; import android.os.Bundle; import android.widget.TextView; import android.widget.Button; import android.view.View; public class MyActivity extends Activity { /** Called when the activity is first

In a my project I am trying to control a car using data obtained through the accelerometer of an Android device. (Left, Right, Forward, Reverse). Even though I have managed to read values from the accelerometer the readings are subject to frequent changes even the device is in a stable position. Can someone provide me a better way to do this? Following is the code that I have used import android.content.Context; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.hardware.SensorManager; public class

Lets say you have the acceleration readings in all the 3 dimensions i.e X, Y and Z. How do you infer using the readings the phone was tilted left or right? The readings get generated every 20ms. I actually want the logic of inferring the tilt from the readings. The tilt needs to be smooth. A tilt can be detected in a sort of diferent ways. You can take into account 1 axis, 2 axis, or the 3 axis. Depending on how accurate you want it, and how much you feel like fighting with maths. If you use only one axis, it is quite simple. Think the mobile is completely horizontal, and you move it like this
