Kotaro Hara gave an invited presentation about the Project Sidewalk at GroupSight workshop, held in Austin Texas during the HCOMP conference this year. In the presentation, Kotaro introduced our work on locating sidewalk accessibility features by combining crowdsourcing, computer vision, machine learning, and Google Street View.

Our project got featured on Technica.ly after giving a presentation at Transportation Tech in Baltimore. See the article here: How this UMD researcher is using Google Street View to make the physical world more accessible.
