Digital Twin Watch helps wheelchair users explore journeys while keeping their mobility requirements and the limits of available evidence visible.

A user describes a journey in natural language. Meta’s muse-spark-1.2 coordinates tools that query live Digitransit/HSL transport services and retrieve relevant urban context. The application checks departure times and total walking/wheeling distance, preserves requirements across follow-up messages, and flags returned options that exceed a hard limit.

Users can preview the returned route in a 2.5D city view and inspect historical Mapillary street photographs. A barrier-reporting workflow supports editable drafts, explicit location confirmation and human review, with demonstration reports separated from real evidence.

The core principle is that unknown accessibility remains unknown. Wheelchair-configured routing does not certify step-free access or a destination entrance.

Built during the hackathon from an initial repository skeleton, the prototype combines existing open datasets and services into a practical foundation for an urban accessibility digital twin. Building heights are estimated, urban context is a dated snapshot, and decorative traffic is explicitly simulated.
