Mariana Shimabukuro

Graduate Student – PhD

I am a Ph.D. student in Computer Science, and my current project relates to educational applications.

I got my Masters of Science degree from the Computer Science program supervised by Dr. Christopher Collins at the University of Ontario Institute of Technology in 2017. My Masters project is titled “An Adaptive Crowdsourced Investigation of Word Abbreviation Techniques for Text Visualizations” where I collected data on how people create abbreviations allowing me to design an abbreviation algorithm.

I have some experience in the industry where I worked with natural language processing (NLP) regarding extraction of named entity recognition (NER) in the context of law cases corpora in Portuguese.

I have also worked with educational technologies applied to introducing programming techniques using robotics. During my undergraduate studies, I joined a group called GISDI, which develops applications for mobile robotics in an educational environment. This environment is taken to schools where programming lessons are given.

While still in university for my undergraduate degree, I was granted a scholarship by the Brazilian government,  named Science Without Borders. Through this scholarship, I was able to spend my third year of undergraduate studies in Canada at the University of Ontario Institute of Technology – UOIT. As an exchange student, I attained a summer position at vialab and started working on my word abbreviation studies.

In 2015, I graduated from the University of State of Sao Paulo – UNESP in Brazil as top of my class in 2015 with a Bachelor’s degree in Computer Science.

In my spare time, I like going to the gym; lifting weights, building muscle and doing some HIIT cardio. Well, I try to be as fit as I can. Once I am a food lover, I work out hard so I can eat more.

    abstract = {Technology has blurred the boundaries of our work and private lives. Using touch-free technology can lessen the divide between technology and reality and bring us closer to the immersion we once had before. This work explores the combination of eye-tracking glasses and a brain-computer interface to enable hand-free interaction with the camera without holding or touching it. Different camera modes are difficult to implement without the use of eye-tracking. For example, visual search relies on an object, selecting a region in the scene by touching the touchscreen on your phone. Eye-tracking is used instead, and the fixation point is used to select the intended region. In addition, fixations can provide context for the mode the user wants to execute. For instance, fixations on foreign text could indicate translation mode. Ultimately, multiple touchless gestures create more fluent transitions between our life experiences and technology.},

    abstract = {In language learning applications, contextualization and immersion rely on real-life communication and remain challenging despite the recent advancements in artificial intelligence (AI) that have significantly impacted educational and language learning experiences. This paper introduces LingoComics, a web application that embeds AI-empowered stories with narrative and comic-style illustrations to enhance contextualization and personalization in language learning. At the core of LingoComics is the Story Designer module, which allows learners to co-author short narratives using a structured set of parameters within a simple user interface. Leveraging OpenAI’s GPT-4-turbo for text completion and DALLE-3 for image generation, the Story Designer generates contextually relatable stories and comic-style images based on user input.
    Future work includes user evaluations, activity designs, and additional language learning support features. LingoComics aims to increase learners’ confidence and motivation by enabling personalized, situational language practice, preparing them for real-life communication.},
