if the player moves in the real world the game object also want to move

Question

I am creating an iOS game. It's my first experience in iOS. I am facing an issue in player movement. If the player moves in the real world this means the game object (character in the game) also wants to move. So I tried to access pedometer to take the step count. But it is not updating. It's showing the step count as 0 only. The value is not changing. Here's my script:

 private float loLim = 0.005F;
 private float hiLim = 0.3F;
 private int steps = 0;
 private bool stateH = false;
 private float fHigh = 8.0F;
 private float curAcc= 0F;
 private float fLow = 0.2F;
 private float avgAcc;

 public Text stepCountTxt;

 public void Update(){
   stepDetector();
 }

 public int stepDetector(){
 curAcc = Mathf.Lerp (curAcc, Input.acceleration.magnitude, Time.deltaTime * fHigh);
 avgAcc = Mathf.Lerp (avgAcc, Input.acceleration.magnitude, Time.deltaTime * fLow);
 float delta = curAcc - avgAcc;
     if (!stateH) {
         if (delta > hiLim) {
             stateH = true;
             steps++;
         }
     } else {
         if (delta < loLim) {
             stateH = false;
         }
     }
     avgAcc = curAcc;
     calDistance (steps);

 return steps;
}

void calDistance(int i){
   stepCountTxt.text=i.toString();
}
