What is NaviLens?

NaviLens is an AI optical code system designed to help blind and visually impaired users handle public spaces independently. The system works by scanning special NaviLens codes placed in buildings, transport hubs, and public areas using a smartphone app. When scanned, the codes provide audio information about the user's location, nearby facilities, directions, and other relevant details. The approach is different from standard QR codes; it uses a proprietary visual system optimised for accessibility. Institutions deploy the codes in their spaces, while users download the app for free and can scan codes to gain situational awareness and handle without requiring sighted assistance or external GPS reliance in indoor environments.

Pros & cons

Advantages

  • Free app for users, removing cost barriers to accessibility
  • Works indoors where GPS is unreliable or unavailable
  • Gives blind users greater independence in navigating unfamiliar spaces
  • Requires only a smartphone, no additional hardware needed
  • Institutions benefit from knowing their spaces are accessible

Limitations

  • Requires institutions to install codes; coverage depends on adoption, so not all public spaces may have them
  • Users need to be near a code to get information, limiting usefulness in spaces without NaviLens deployment
  • Relies on institutions keeping information associated with codes current and accurate

Use cases

Navigating train stations and airports with NaviLens codes installed

Finding facilities and services within hospitals or university campuses

Independent travel in museums or cultural institutions that have deployed codes
