My name is Lucius Vinicius Rocha Machado Filho. My academic path started with the Licentiate Degree in Informatics Engineering in 2019, where I made part of the team of the Informatics Engineering Nucleus for the maintenance of its official website. In 2021, I did a summer internship for the company EVOKE IT – Innovation Studio where I worked with fullstack for the development of customized machines and web applications. The final project of the licentiate degree consisted in the construction of a robotic football narrator where the user could alter personality parameters like “energetic,” “angry,” or even intentional bias for one of the teams. Besides, the project demonstrated the match in 3D models in real time, where the player possessed the capacity to move the camera freely, or even go to any point in the timeline.

In 2022 I decided to do the Master’s in Digital Game Development, since it was always an area of interest. During the Master’s, I participated in two Research Scholarships to work with fullstack for data visualization of material behavior, and its respective API. The project also included the creation of a Python library to simplify the interaction for future developers. During the Master’s, I chose the optional discipline “Multimodal Interaction,” where it was my first contact with forms of alternative interaction for programs. In this discipline, it was developed a program that plays chess through the combination between body gestures and voice commands, besides implied contexts, like identifying if there is more than one possible move with the given command or not.

My Master’s Dissertation consisted in the development of an accessible game to assist the education of a child with Cerebral Palsy (CP) in a Conservatory of Music. Since CP consists of a set of symptoms that mainly cause motor limitations, the child interacted with the program through their gaze with an eye-tracker. The game was validated after tests with teachers, including from the own Conservatory of Music, designers, and music students. Currently, it is used in the Conservatory of Music to assist in the child’s classes. While working on this project, I awakened a passion in the accessibility area.

Currently I am in the Doctoral Program in New Media, started in 2024, with the objective to evolve my previous work done in the Master’s. The game had the potential of new functions, besides having identified difficulties for the design of interactive applications with the gaze, which caused motivation to continue exploring the area. Two articles were written and submitted to conferences. The work was also presented at the World Conference on Qualitative Research (WCQR) 2025, where it had positive international opinions. One of the works was an Integrative Literature Review about good eye-tracker design practices. Results indicate that there are scientific gaps in this area, and my objective during this Doctoral Program is to explore them while developing an inclusive musical game for the child with CP and others with motor limitation. By the end, it is expected a fully functional inclusive game to assist musical education and guidelines about those good practices to help future developers, designers and researchers plan eye-gaze applications.
