[How to detect object that is being focused ?]

Hi @Corvus
I have tried the script and it return object name. but when I recall it in the update function to keep tracking where the player is looking it is freeze unity after hit play button. I also note when disable a script that recall the eye data from SRanipal it works fine. can you help me how to make it work to capture focus using update function?.  I have used the following script to get eye data using SRanipal eye frame and i want to incluse the detected object to the update section:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;
using System.Threading;
using System.IO;
using ViveSR.anipal.Eye;
namespace Test120FPS
{
    public class Sample_GetDataThread : MonoBehaviour
    {
        public GameObject Status;
        private string state;
        public GameObject Car;
        private string Carx;
        private string Cary;
        private string Bicyclex;
        private string Bicycley;
        private string distance;
        public GameObject Bicycle;
        public EyeData data = new EyeData();
        private Thread thread; private const int FrequencyControl = 1;
        private const int MaxFrameCount = 3600;
        void Start()
        {
            thread = new Thread(QueryEyeData);
            thread.Start();
            
            string text =  "distance"+ "?" + "Carx" + "?" + "Cary" + "?" +"Bicyclex" + "?" +"Bicycley"+"?"+"Left eye dia: "+"?" + "Right eye dia: " + "?" + "Left eye openess " + "?" + "Right eye openess " + "?" + "Left eye gaze " + "?" + "Right eye gaze " + "?" + "Status" + "?" + "CurrentFrameSequence" + "?" +  "CurrentSystemTime(ms)"  + Environment.NewLine;
            File.AppendAllText("DataRecord.txt", text);
        }
        private void OnApplicationQuit()
        {
            thread.Abort();                
        }
        private void OnDisable()
        {
            thread.Abort();
        }

      

        /// <summary>
        /// Checks name for current object in focus.
        /// </summary>
        

        void FixedUpdate()
        {
            Carx = Car.transform.position.x.ToString();
            Cary = Car.transform.position.z.ToString();
            Bicyclex = Bicycle.transform.position.x.ToString();
            Bicycley = Bicycle.transform.position.z.ToString();
            state = Status.name.ToString();
            float dist = Vector3.Distance(Car.transform.position, Bicycle.transform.position);
            float feet = dist * 3.28f;
            distance = ((int)dist*3.28f).ToString();
            
            

        }

        // You can only use C# native function in Unity's thread.
        // Use EyeData's frame_sequence to calculate frame numbers and record data in file.
