Trying to track the direction of a swipe and then apply additional force to an object moving in that direction

I realize this question is probably ridiculously rudimentary, but this is literally the first batch of code I have written ever, in any language. After going through 2 or 3 coding and Unity3D books, I figured it was time to just sit down and start coding. Apologies in advance for my messy code and (probably) incorrect assumptions. I'll get it eventually :)

The gist of my prototype is I want to let the player swipe and object around the space, but I want the speed and thrust velocity to be controlled by a script. So, for instance, if the player swipes up, I want to get the normalized direction of the swipe, and then move the object in that direction. The catch is that I want the object to be powered by a motor that has nothing to do with the swipe speed or end position. So the script should grab the direction and say "Ok, I can move this object in that direction at the speed and power dictated in the script."

Hoping that makes sense, here is what I have so far. It is not complete, (the smash function is missing) but I wanted to know if I was on the right track

 #pragma strict
 
 var horizontalSpeed : float;
 var verticalSpeed : float;
 var thrust : float;
 var thrustsRemaining : int;
 var touch : Touch;
 var direction : Vector2;
 
 
 function Start () {
     Init ();
 }
 
 function Init () {
     thrustsRemaining = 2;
 }
 
 function Update () {
     if (Input.touchCount == 2 && Input.GetTouch(0).phase == TouchPhase.Moved) {
         touch = Input.touches[0];
         CheckDirection ();
     }
 
 }
 
 function CheckDirection () {
     direction = touch.deltaPosition.normalized;
     
     if (touch.TouchPhase.Began.y < touch.TouchPhase.Ended.y || touch.TouchPhase.Began.y == touch.TouchPhase.Ended.y) {
         Thrust ();
     } else if (touch.TouchPhase.Began.y > touch.TouchPhase.Ended.y) {
         Smash ();
     }
 }
 
 function Thrust () {
     if (thrustsRemaining > 0) {
     transform.Translate (touch.x * thrust * horizontalSpeed * verticalSpeed * touch.y * time.deltaTime)
     thrustsRemaining--;
     }
 }
