Detecting touch events left and right side

How can I simultaneously detect the touch events left and right side with each side has different touch functionality implementation.38970-touch.png

foreach (Touch touch in Input.touches) {
if (touch.position.x < Screen.width/2) {
Movement();
}
else if (touch.position.x > Screen.width/2) {
ShootNPunch();
}
}

For work with multitouch see my example (write on CSharp):

 private int finId1 = -1; //id finger for cancel touch event
 private int finId2 = -1;

 void Start() {
  Input.multiTouchEnabled = true; //enabled Multitouch
 }

 void Update() {
  //First check count of touch
  if (Input.touchCount > 0) {
   foreach (Touch touch in Input.touches) {
    //For left half screen
    if (touch.phase  == TouchPhase.Began && touch.position.x <= Screen.width && finId1 == -1) {
     //Do something: start other function
     finId1 = touch.fingerId; //store Id finger
    }
    //For right half screen
    if (touch.phase  == TouchPhase.Began && touch.position.x > Screen.width && finId2 == -1) {
     //Do something
     finId2 = touch.fingerId;
    }
    if (touch.phase == TouchPhase.Ended) { //correct end of touch
     if(touch.fingerId == finId1) { //check id finger for end touch
      finId1 = -1;
     } else if(touch.fingerId == finId2) {
      finId2 = -1;
     }
    }
   }
  }
 }

I hope that it will help you.
