Please critique my gesture event handling

Unity Engine

I want to implement something like Unity’s IPointer handlers for gesture detection but I don’t really have any ideas that feels nice and clean, this is the direction I’m currently going with:

public interface IGestureControlHandler {
    void onSwipe(Vector2 dir);
    void onTap(Vector2 pos);
    void onDoubleTap(Vector2 pos);
    void onPinch(Vector2 thumbMvmt, Vector2 indexMvmt);
}

public class GestureControl : MonoBehaviour {
   IGestureControlHandler receiver;
   public void setEventReceiver(IGestureControlHandler planeController) {
      receiver = planeController;
   }

   void Update() {
      if(Input.touchCount > 0) {
         // Gesture detection stuff
         if(receiver != null) {
            Vector2 swipeDir = Vector2.whatever;
            receiver.onSwipe(swipeDir);
         }
      }
   }
}

And in whatever GameObject that needs gesture detection:

public class PlaneController : MonoBehaviour, IGestureControlHandler {

   void Awake() {
      gameObject.AddComponent<GestureControl>().setEventReceiver(this);
   }
   
   public void onSwipe(Vector2 dir) {
      throw new System.NotImplementedException();
   }
   public void onTap(Vector2 pos) {
      throw new System.NotImplementedException();
   }
   public void onDoubleTap(Vector2 pos) {
      throw new System.NotImplementedException();
   }
   public void onPinch(Vector2 thumbMvmt, Vector2 indexMvmt) {
      throw new System.NotImplementedException();
   }
}

I feel pretty disgusted by this tbh:

what do you think I can do to make it better?

I’d enforce a single independent instance of GestureControl. I’d get rid of the interface. I’d put static events in GestureControl. This way, objects can subscribe to gestures they’re interested in exclusively and the input processing code is ran only once.
