Accessibility at CMU

We design, make and study technology to make the world accessible.


We are researchers, teachers, and people with disabilities at CMU making the world more accessible.

Jeffrey P. Bigham

is an associate professor in HCII and LTI. He builds access technology combining machine learning, NLP, and computer vision with the on-demand labor of people from the web (the crowd). He also manages this web page.

Patrick Carrington

Patrick Carrington

is a Postdoctoral Fellow in HCII. Patrick's work focuses on applications and devices for wheelchair users to support access, independence, engagement, and quality of life. His research has focused on "chairables", mobile and wearable technologies physically designed to centrally consider the wheelchair user and integrate in and around the wheelchair.

Cole Gleason

Cole Gleason

is a Ph.D. student in HCII, and his work focuses on helping people with visual impairments get around and explore the world more independently using crowdsourcing and computer vision.

Anhong Guo

Anhong Guo

is a PhD student in HCII. He works on leveraging the increasing availability of wearable devices and bringing together the strengths of computer vision and crowdsourcing to solve accessibility issues.

Aaron Steinfeld

is an associate research professor in RI. He works on helping people get places and get things done with universal design, intelligent transportation systems, crowdsourcing, human-robot interaction, and machine learning.

Kristin Williams

Kristin Williams

is a PhD student in HCII. She is interested in how wearable computing and augmented reality could facilitate functional communication in contexts demanding a high degree of linguistic skill.
