Smooth tilt acceleration

hi, i did a code to make my gameobject move when my iPhone/iPad is tilted, but i’m not satisfied of my gameobject’s movement and i’m wondering if there is a way to make the movement smoother. Here is my code :

private var speed = 10.0;

function Update ()
{
	var dir : Vector3 = Vector3.zero;
	dir.x = Input.acceleration.x;

	if (dir.sqrMagnitude > 0.3)
	{
		dir.Normalize();
		dir *= Time.deltaTime;
		transform.Translate (dir * speed);
	}
}

thanks

Check answer by @aldonaletto for details in this question Accelerometer question.

The script from the answer is:

// Move object in XY using accelerometer (home button at right hand)
var speed: float = 6.0;
var filter: float = 5.0;

private var accel: Vector3;

function Start(){
    accel = Input.acceleration;
}

function Update(){
    // filter the jerky acceleration in the variable accel:
    accel = Vector3.Lerp(accel, Input.acceleration, filter * Time.deltaTime);
    // map accel -Y and X to game X and Y directions:
    var dir = Vector3(-accel.y, accel.x, 0);
    // limit dir vector to magnitude 1:
    if (dir.sqrMagnitude > 1) dir.Normalize();
    // move the object at the velocity defined in speed:
    transform.Translate(dir * speed * Time.deltaTime);
