I am a Ph.D. student at Human-Computer Interaction Institute (HCII) at Carnegie Mellon University (CMU), advised by Dr. Jeffrey Bigham and Dr. Amy Pavel. My current research focuses on designing and building interactive tools to support accessible media consumption and content production.

Before joining CMU, I was a member of HCI Lab at National Taiwan University (NTU), advised by Dr. Mike Y. Chen and Dr. Lung-Pan Cheng. As an undergraduate research assistant, I explored and developed several different enabling and inclusive systems across mixed-reality, mobile and wearable interfaces (see publication page for details).

Selected Research
A presenter view of a slide from a lecture where most text is in black but some of the text has been colored green to represent that it has been spoken by the presenter (as the speaker said 'activity: create a colorful circle brush'). There is an image with a squiggly circle brush on the slide highligted with green border to indicate that the image has also been mentioned.
Say it all: Feedback for Improving Non-Visual Presentation Accessibility


An authoring system that visualize real-time and post-hoc accessibility feedback for speakers to deliver more accessible presentations.
