Research highlights

Real-time captioning and sound awareness support

With advances in wearable computing and machine learning, Leah Findlater and I have been investigating new opportunities for real-time captioning and sound awareness support for people who are deaf/Deaf and hard of hearing (DHH). Our work spans three primary areas: real-time captioning in augmented reality and wearables (ARCaptions), sound awareness support in the “smart home” (HomeSound), and real-time sound identification on smart watches (SoundWatch, website forthcoming). Throughout this work, we’ve engaged with over 250 DHH participants to help identify design opportunities, pain points, and to solicit feedback on our designs.

Project Sidewalk

Project Sidewalk combines remote crowdsourcing + AI identify and assess sidewalk accessibility in online imagery. Working with people who have mobility disabilities, local government partners, and NGOs, we have deployed Project Sidewalk into five cities (Washington DC, Seattle, WA, Newberg, OR, Columbus, OH, and Mexico City, MX), collecting over 500,000 geo-tagged sidewalk accessibility labels on curb ramps, surface problems, and other obstacles.
