A community-driven system allows users to share updates, photos, and report accessibility issues in real time. The project aims to increase independence, safety, and confidence in navigating cities, starting with Venice and expanding globally.

This application helps people with reduced mobility, stroller users, and individuals with visual or hearing impairments navigate urban environments. It provides accessibility information such as ramps, elevators, stairs, and accessible entrances.

The application suggests paths that provide sufficient width for strollers, with a minimum clearance of 90 centimetres. It automatically avoids stairs, narrow bridges, uneven cobblestones, and slippery surfaces. Priority is given to ramps, elevators, and level streets to ensure a smooth and safe journey for parents with young children

For each bus, tram, metro, or vaporetto stop, the app clearly indicates which entrances are suitable for stroller access. It also shows whether there is designated space for a stroller inside the vehicle and warns about large gaps or steps between the platform and the door. This helps parents plan their trip without unexpected obstacles at the station.

Users pushing a double or twin stroller can filter routes that require a minimum width of more than 75 centimetres. The application provides warnings about revolving doors or narrow turnstiles that cannot accommodate larger strollers. It also highlights wider ramps and extra‑wide elevator doors to make travelling with two children as convenient as travelling with one.

Dubo is built for users who have low vision, difficulty distinguishing colors, or other visual limitations. The app never relies on color alone to convey critical information. Instead, it combines high-contrast text, clear icons, patterns, labels, voice guidance, and vibration alerts. Every obstacle — stairs, narrow bridges, broken elevators, or roadworks — is announced audibly and shown as a simple text message. This ensures that no one misses important updates, regardless of how they perceive the screen.
