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

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(); }
