Accelerometer Problem.

[Hardik Trivedi]

Hi Friends,

I am doing some stuff with accelerometer. I am able to access this sensor using Sensor Listener service.As you all know it gives three values X,Y and Z. Now what this values are.
I got some info from google. But still I am not sure about it.

Can anyone elaborate those three values to me? I want to detect that user is walking or not? I want to detect the distance the user has walked.

Please Help.

I would suspect that the three values represent the acceleration in each of the three directions of a 3-D graph (you know, that boring geometry stuff you slept through in math class ;) ). My guess is that if you lay your phone flat, the X axis goes left/right relative to the device, the Y axis goes forward/backwards (or rather away from the top and bottom of the device), while Z is up/down (that is upwards from the screen or downwards from the back of the device). A simple app that displays the values should be able to verify this.

I google and found this post which seems to agree the directions: http://www.anddev.org/accessing_the_accelerometer-t499.html
