which demanded some temporary adjustments to the structure of four undergraduate and two graduate courses. I am also grateful for all student participants for their time, dedication, and seriousness.Finally, this work would not be possible without the financial support of CAPES and material support of Caverna Digital, a laboratory of the Electric Engineering faculty and pioneer in Virtual Reality in Brazil since its foundation two decades ago. Congratulations to the lab and all personnel for the twenty-year birthday! I am very proud to be part of this group for more than seven years and to take part in many glorious achievements. There are still many more to come.
