Hi @haramchoi, you could use code along the following lines to get dwell time:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Tobii.G2OM;

public class HighlightAtGaze : MonoBehaviour , IGazeFocusable
{
    private float _totalGazeTime;
    private bool _hasFocus;
    
    public void GazeFocusChanged(bool hasFocus)
    {
        _hasFocus = hasFocus;
        if (!hasFocus)
        {
            Debug.LogWarning($"{gameObject.name} : {_totalGazeTime}");
        }

    }

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (_hasFocus)
            {
                _totalGazeTime += Time.deltaTime;
            }
    }
}

Let me know how it goes. Best Wishes.
