Please join us tomorrow at the Change Seminar. Anat Caspi from the Taskar Center for Accessible Technology (TCAT) will be joining us to talk about equitable pedestrian wayfinding. *What: *Equitable pedestrian wayfinding *When: *Tuesday, Nov 15 *Where: *The Allen Center, CSE 203 *Abstract:* As pedestrians, we each experience the built environment differently. Our physical abilities greatly impact our access to the world and resources around us. Equitable pedestrian wayfinding is crucial for a barrier-free city, where people with different abilities can independently access customized, relevant, and up-to-date routing information. Pedestrians present heterogeneous information requirements consisting of static and transient information ranging from elevation changes to curb ramps to transient sidewalk surface conditions. However, such data, including the location of sidewalks, are generally unavailable in a user-consumable format. Moreover, existing routing solutions primarily optimize for distance, for instance, offering inappropriate routes with steep inclines that are unusable by many manual wheelchair users. A data model for equitable pedestrian wayfinding must flexibly support an annotated pedestrian network: a connected graph model that can be visualized and populated with data to parametrize a personalizable cost function. In this talk, we will present the current AccessMap capabilities (and discuss those in progress) that enable ability-based pedestrian routing. *About TCAT* The Taskar Center for Accessible Technology <https://tcat.cs.washington.edu/> (TCAT) at the University of Washington Department of Computer Science & Engineering develops and deploys technologies that increase independence and improve quality of life for individuals with motor and speech impairments. Anat Caspi is director of TCAT.
