AI-Powered Wearable Navigation System for the Visually Impaired

healthPilotedTRL 7

Imagine a virtual guide dog built into a pair of glasses. Instead of a dog pulling a leash, these glasses use sensors and AI to 'pull' the wearer's head in the right direction. It tells the user where they are and how to get home using sounds and gentle vibrations on the forehead.

The business problem

What needed solving

Traditional mobility aids for the blind are either outdated (canes) or non-scalable and expensive (guide dogs), leaving millions of people unable to be educated or employed.

The solution

What was built

A head-worn wearable device featuring AI for image/sound processing, 3D environment mapping, and a haptic/auditory feedback system.

Who can put this to work

Assistive Technology
mid-size
Target: Medical device distributors

If you are a medical device distributor dealing with the scarcity of guide dogs—where only 28,000 exist for 40 million blind people—this project developed a wearable headset that mimics guide dog benefits without the high cost and care requirements.

Public Infrastructure
any
Target: Smart city accessibility consultants

If you are a consultant dealing with urban mobility barriers for the 238 million visually impaired people, this project developed a 3D environment understanding system that helps users navigate to specific points of interest.

Consumer Electronics
enterprise
Target: Wearable tech manufacturers

If you are a manufacturer dealing with the need for specialized haptic interfaces, this project developed a head-worn device with integrated cooling, miniaturized sensors, and forehead-based impulse feedback.

Frequently asked

Quick answers

What is the cost advantage over traditional solutions?

Based on available project data, training a single guide dog costs between $30-$60K, whereas .lumen is designed to be an affordable and scalable alternative.

Can this be scaled to a global market?

Yes, the target market is significant, with 40 million blind and over 238 million visually impaired people worldwide struggling with mobility.

What is the status of the intellectual property?

Based on available project data, the team has already made progress with patents and research iterations.

How does the device integrate with the user's movement?

The system uses a combination of haptics and auditory feedback to guide the user by 'pulling' their head toward a destination.

What is the development timeline for market entry?

The project period ran from 2022-11-01 to 2024-10-31, focusing on finalizing the product and piloting it for market entry.

Consortium

Who built it

The project is led by a single Romanian SME, DOTLUMEN SRL. With a 100% industry ratio and no university or research partners, the project is lean and focused entirely on commercial product development and market entry.
