Mobile Device Input!

Hi guys! I'm trying to build a 2d game and below script is my character "PlayerControl" script. It works fine on Horizontal axis with arrow keys but how should i implement touch input for mobile devices to move my character in right and left direction. Please can somebody help me?? Thanks in advance....

using UnityEngine;
using System.Collections;

public class PlayerControl : MonoBehaviour
{
[HideInInspector]
public bool facingRight = true; // For determining which way the player is currently facing.
[HideInInspector]
public bool jump = false; // Condition for whether the player should jump.


public float moveForce = 365f; // Amount of force added to move the player left and right.
public float maxSpeed = 5f; // The fastest the player can travel in the x axis.
public AudioClip[] jumpClips; // Array of clips for when the player jumps.
public float jumpForce = 1000f; // Amount of force added when the player jumps.
public AudioClip[] taunts; // Array of clips for when the player taunts.
public float tauntProbability = 50f; // Chance of a taunt happening.
public float tauntDelay = 1f; // Delay for when the taunt should happen.


private int tauntIndex; // The index of the taunts array indicating the most recent taunt.
private Transform groundCheck; // A position marking where to check if the player is grounded.
private bool grounded = false; // Whether or not the player is grounded.
private Animator anim; // Reference to the player's animator component.
GameObject hero;

void Awake()
{
// Setting up references.
groundCheck = transform.Find("groundCheck");
anim = GetComponent<Animator>();
}


public void Update()
{
// The player is grounded if a linecast to the groundcheck position hits anything on the ground layer.
grounded = Physics2D.Linecast (transform.position, groundCheck.position, 1 << LayerMask.NameToLayer ("Ground"));

// If the jump button is pressed and the player is grounded then the player should jump.
if (Input.GetButtonDown ("Jump") && grounded)
jump = true;
}


void FixedUpdate ()
{
// Cache the horizontal input.
float h = Input.GetAxis("Horizontal");

// The Speed animator parameter is set to the absolute value of the horizontal input.
anim.SetFloat("Speed", Mathf.Abs(h));

// If the player is changing direction (h has a different sign to velocity.x) or hasn't reached maxSpeed yet...
if (h * GetComponent<Rigidbody2D> ().velocity.x < maxSpeed)
// ... add a force to the player.
GetComponent<Rigidbody2D>().AddForce(Vector2.right * h * moveForce);

// If the player's horizontal velocity is greater than the maxSpeed...
if(Mathf.Abs(GetComponent<Rigidbody2D>().velocity.x) > maxSpeed)
// ... set the player's velocity to the maxSpeed in the x axis.
GetComponent<Rigidbody2D>().velocity = new Vector2(Mathf.Sign(GetComponent<Rigidbody2D>().velocity.x) * maxSpeed, GetComponent<Rigidbody2D>().velocity.y);

// If the input is moving the player right and the player is facing left...
if (h > 0 && !facingRight)
// ... flip the player.
Flip ();

// Otherwise if the input is moving the player left and the player is facing right...
else if(h < 0 && facingRight)
// ... flip the player.
Flip();

// If the player should jump...
if(jump)
{
// Set the Jump animator trigger parameter.
anim.SetTrigger("Jump");

// Play a random jump audio clip.
int i = Random.Range(0, jumpClips.Length);
AudioSource.PlayClipAtPoint(jumpClips, transform.position);

// Add a vertical force to the player.
GetComponent<Rigidbody2D>().AddForce(new Vector2(0f, jumpForce));

// Make sure the player can't jump again until the jump conditions from Update are satisfied.
jump = false;
}
}


void Flip ()
{
// Switch the way the player is labelled as facing.
facingRight = !facingRight;

// Multiply the player's x local scale by -1.
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}


public IEnumerator Taunt()
{
// Check the random chance of taunting.
float tauntChance = Random.Range(0f, 100f);
if(tauntChance > tauntProbability)
{
// Wait for tauntDelay number of seconds.
yield return new WaitForSeconds(tauntDelay);

// If there is no clip currently playing.
if(!GetComponent<AudioSource>().isPlaying)
{
// Choose a random, but different taunt.
tauntIndex = TauntRandom();

// Play the new taunt.
GetComponent<AudioSource>().clip = taunts[tauntIndex];
GetComponent<AudioSource>().Play();
}
}
}


int TauntRandom()
{
// Choose a random index of the taunts array.
int i = Random.Range(0, taunts.Length);

// If it's the same as the previous taunt...
if(i == tauntIndex)
// ... try another random taunt.
return TauntRandom();
else
// Otherwise return this index.
return i;
}
}

Thanks! I'll let you guys know after implementing it.
