Explore an innovative lecture on developing interactive tools to address global challenges in accessibility and STEM education. Delve into Jon Froehlich's research at the University of Washington and University of Maryland, focusing on two major threads: making the physical world more accessible for people with disabilities and engaging children in STEM learning through wearables and e-textiles. Discover projects like Project Sidewalk, which uses crowdsourcing and machine learning to identify street-level accessibility issues, and MakerWear, a construction toolkit enabling young children to create interactive e-textiles. Gain insights into the key contributions of these projects and their potential future developments in this 56-minute talk from the Paul G. Allen School Colloquia series.
