I am a postdoctoral fellow working in the Human-Computer Laboratory at Ewha Womans University in Seoul, South Korea. There I perform research to develop multimodal interaction techniques to increase the access of people with disabilities to art, education, and mobility to improve their quality of life.
Despite the Braille slate being the most popular method used by visually impaired people to write Braille on paper, there is a lack of tools that facilitate independent learning and practice. In addition, there is limited opportunity to use it beyond writing on a piece of paper. This project explores using an interactive Braille Slate as a text input interface for touchscreen devices and independent practice.
This work explores the development of a mobile application to make riding a bus more accessible by leveraging machine learning algorithms to provide navigation guidance to take, ride, and descend public bus transportation.
Typing on mobile devices without looking at the screen is prone to errors. Usually, characters are typed by tapping gestures that trigger audio and haptic feedback. Modern smartphones are capable of sensing the pressure of the user's finger on the screen. This project explores developing and evaluating pressure-based gestures to type text.
