Resumo

Information on urban accessibility barriers is often unavailable or outdated. This paper presents AcessoMap Video, a Progressive Web Application (PWA) for collaboratively documenting these barriers through short georeferenced videos. Its architecture processes media directly in the browser: face detection suggests privacy masks, users review temporal tracks and keyframes, and a visually sanitized copy is generated before publication. The resulting video excludes the original audio track, while geographic coordinates are quantized to a grid with an approximate spacing of 50 m. Reported occurrences are published on a collaborative map, where they can be confirmed or disputed by the community, and exported in CSV and GeoJSON formats. Preliminary functional validation verified the integrated recording and publication workflow; however, sanitization effectiveness and the computational and human effort required for review still need quantitative evaluation. The source code, configuration files, and reproduction instructions are included in a versioned research artifact prepared for archiving on Zenodo under the MIT License.
