Taskar Center for Accessible Technology

What Taskar Center for Accessible Technology does

The Taskar Center for Accessible Technology (TCAT) is an academic research and translation center housed within the Paul G. Allen School for Computer Science & Engineering at the University of Washington in Seattle. Founded around 2014-2015, TCAT develops open-source accessible technologies organized around three pillars: Mobility + Transportation, Non-Ableist AI, and Work + Play. Its core product portfolio includes AccessMap, a free web application for personalized pedestrian routing that uses slope, curb ramp, crossing, and surface data to plan routes reflecting individual mobility needs; OpenSidewalks, an open schema specification for pedestrian infrastructure compatible with OpenStreetMap; iOSPointMapper, an iOS field-capture app that runs on-device AI semantic segmentation with LiDAR, GPS, and human-in-the-loop validation so that no raw imagery leaves the device; and TDEI, a Transportation Data Exchange Initiative building open-source data collection tools and governance models under the U.S. DOT ITS4US Deployment Program. Additional products include the OS-CONNECT statewide sidewalk inventory for Washington, the APE annotated pedestrian environment dataset spanning 2,700 km², Tactile MapTile, FleXR (a WebXR/A-Frame accessibility plugin), an Autonomous Wheelchair add-on kit with on-board machine intelligence, and Next Gen Augmentative Communication tools.

TCAT's business model is grant-funded research rather than commercial software sales. All tools, applications, and datasets are free to use, and the center's revenue derives primarily from Washington State legislative appropriations (notably ESHB 1125 Section 111 for OS-CONNECT), the ITS4US Deployment Program, and university institutional support. GTM motion is community-led: TCAT engages students worldwide, faculty, partner communities, and disability advocates through participatory design, open-source contribution, volunteer mapathons, and conference dissemination. Customer segments include people with disabilities (primary end users of AccessMap and Tactile MapTile), state and county transportation agencies and planners (primary institutional users of OpenSidewalks, OS-CONNECT, and TDEI), and researchers and accessibility advocates. The center is led by founder and director Dr. Anat Caspi and operates with approximately 10 staff.

TCAT has no patents and minimal commercial revenue mechanics; its primary strategic asset is the integration of an open data standard (OpenSidewalks), a statewide dataset (OS-CONNECT), a field-capture pipeline (iOSPointMapper), and a routing application (AccessMap) into a single participatory design loop.

Expansion highlights5 records

Broad incumbents

• Apple Maps: Apple's mapping platform with built-in accessibility features including wheelchair routing and detailed transit/pedestrian information. Comparable in serving accessible-routing end-users, but as a broad incumbent rather than a disability-community-led effort.
• HERE Technologies: Major location-data and mapping platform supplying pedestrian and transit network data to enterprises and cities. Comparable in providing pedestrian-network data products for transportation agencies, but as a broad commercial incumbent rather than an open accessibility-first schema.
• Moovit: Mass-market transit and mobility app (owned by Intel) with accessibility features and GTFS-based routing. Comparable in serving accessible-trip planning at scale, but as a broad incumbent across all transit modes rather than a pedestrian-accessibility specialist.
• Google Maps: Widely used mapping platform with wheelchair-accessible routing and crowdsourced Local Guides data. Comparable in offering accessible pedestrian navigation, but as a broad incumbent with vastly larger data resources rather than a specialized accessibility data source.

Others

• Aira: Remote visual-interpretation service connecting blind and low-vision users with trained agents via smart glasses. Not a direct mapping competitor, but adjacent in the disability-tech ecosystem TCAT serves, and complementary to AccessMap's screen-reader routing.

Direct peers

• Wheelmap: Community-driven wheelchair-accessibility mapping platform built on OpenStreetMap (by Sozialhelden e.V.). Closest direct comparable to AccessMap: both let users find and contribute accessibility-tagged places and routes via open map data.
• NaviLens: AI-based wayfinding system using computer-vision tags readable at distance for blind and low-vision users in transit and public spaces. Comparable to TCAT's computer-vision accessibility work (iOSPointMapper, Tactile MapTile) and mission to expand mobility for visually impaired users.
• Lazarillo: Indoor and outdoor accessible wayfinding app for blind and low-vision users, with beacons and a navigation API. Comparable to AccessMap's screen-reader navigation and Tactile MapTile's spatial-understanding goals for visually impaired users.
• Project Sidewalk: Also a University of Washington project, using crowdsourced street-level imagery and machine learning to map sidewalk accessibility. Direct comparable to OS-CONNECT/APE: similar academic pedigree, ML-based pedestrian feature detection, and sidewalk-inventory goals.
• AccessNow: App-based crowdsourced accessibility mapping for venues, sidewalks, and transit. Comparable to AccessMap in end-user mission — helping people with disabilities navigate the built environment — though more venue-focused than pedestrian-network-focused.
