Hi, I'm Toshi!

I'm an aspiring game developer turned academic after developing a passion for:

Teaching

I believe usability principles and visualization techniques can significantly enhance students' understanding of complex and abstract concepts.

Selected courseware I've developed:

• Python Gym: a web app for learning Python with instant feedback.
• Active Handout Astro: a framework for interactive course development built with Astro.

You can also check my other projects here.

HCI Research

I'm interested in exploring how a user's gaze can be utilized as an element of interaction with computer systems.

Selected research I've developed in the past:

• EyeSwipe: gaze-based text entry method analogous to keyboard swiping on smartphone
• CameraMouseSuite: a camera-based mouse-replacement interface.

About me

I am an Assistant Professor in Computer Science and Engineering at Insper, where my primary focus is on teaching. I earned my PhD in Computer Science from the University of São Paulo (USP) in 2018, advised by Prof. Carlos Hitoshi Morimoto and Prof. Margrit Betke (Boston University).

My doctoral research concentrated on assistive technologies for individuals with severe motor disabilities, including quadriplegia. Specifically, I developed gaze-based applications using eye trackers, including two text entry methods: EyeSwipe and Swipe&Switch, which are designed to work similarly to the swipe functionality found on smartphone keyboards.
