Kinect and raycast, can't get it done

Hi everyone, I'm working on a project where i use a Kinect V1, with the asset "kinect with MS-SDK", and also if I got all the gestures and joint tracking I need, I'm not able to implement a simple "hover" status.

I'm using the raycast on the Hand Indicator implemented by the "kinect with ms-sdk" framework and trying to catch 4 areas with a collider on them, but yet not a single object is hit.

This is the code I'm using on my HandCursor Object, which is the one tracking user's right hand:

 using UnityEngine;
 using System.Collections;
 
 public class HandScript : MonoBehaviour {
 
     Transform target;
     Camera camera;
     
     void Start() {
         target = transform;
         camera = Camera.main;
     }
     
     void Update() {
 
     }
 
     void FixedUpdate(){
         Vector3 screenPos = camera.WorldToScreenPoint(target.position);
         Debug.Log("target is " + screenPos.x + " pixels from the left and "+ screenPos.y + " pixels from bottom");
         Vector3 fwd = transform.TransformDirection(Vector3.forward);
         Ray ray = camera.ScreenPointToRay(screenPos);
         ray.direction = fwd;
         
 
         RaycastHit hit;
         if(Physics.Raycast(ray, out hit, 200f))
             print("There is something in front of the object!");
         Debug.DrawRay(ray.origin, ray.direction * 200, Color.yellow);
     }
 }

Then I have a canvas with an image inside and 4 empty gameobjects with a collider to trigger the raycast, but seems I'm doing something wrong :(

Any help is apreciated and thanks in advance guys :)
