About 3.6 million adults in the United States use a wheelchair to get around, according to census data. However, it's farily difficult for those people to navigate the sidewalks of cities. University of Washington researchers have led the development of Project Sidewalk, an online crowdsourcing game that lets anyone with an internet connection use Google Street View to virtually explore neighborhoods and label curb ramps, missing or rough sidewalks, obstacles and more. Project Sidewalk first launched in Washington, D.C., and it's now available in Newberg, Oregon -- near Portland -- and Seattle.
