ABOUT          CURRENT PROJECTS          PUBLICATIONS          AWARDS         WORK


I am a PhD student in Computer Science Dept. at University of Maryland, College Park. My research is about machine learning for blind people. Specifically, my current projects investigate the use of automatic speech recognizer and teachable object recognizer by blind users. My advisor is Professor Hernisa Kacorri in iSchool at University of Maryland, College Park.
CURRENT PROJECTS
Correcting Errors in Speech Input During Non-Visual Use

While speech input has improved dramatically in the past few years, reviewing and editing the dictated text during non-visual use is a known challenge. We are studying how well users can identify dictation errors based on text-to-speech output. We are also designing and evaluating mechanisms to improve speech-based error identification and correction during non-visual use.
Mobile Object Recognizers for Blind Users

The advance of machine learning enhances mobile devices to be used for people with disabilities. For example, a computer vision technique helps visually impaired users identifying objects with their mobile devices. In this project, we aim to improve the interface for visually impaired people to train their mobile devices for object recognition using deep learning and Tensorflow.
