Experience the .lumen Glasses at SightCity 2026 in Frankfurt

There are few places in Europe where the future of assistive technology is discussed as directly, practically, and meaningfully as at SightCity. This year, .lumen will be there.

From 27–29 May 2026, we will join the SightCity community in Frankfurt to present the .lumen Glasses for the Blind, meet blind and visually impaired visitors, speak with mobility and rehabilitation professionals, and connect with partners working to make independent mobility more accessible.

For us, it's a real honour to be part of this event.

SightCity is one of the most important meeting points for the blind and visually impaired community, assistive technology companies, researchers, distributors, associations, public institutions, and accessibility professionals. It is where people come not just to hear about new solutions but to test them, question them, compare them, and understand if they can truly help in everyday life. Exactly the kind of conversation we want to have.

Update from SightCity 2026

SightCity became exactly the kind of conversation we hoped for: direct, practical, honest, shaped by the people who understand assistive technology best.

During the event, the .lumen booth became one of the places people kept returning to: to test, ask questions, compare, challenge, and understand what AI-powered mobility could mean in real life.

Benjamin Hofer, Team Lead Platform at Gridscale, described .lumen as “one of the most innovative solutions at this year’s trade fair” and added: “And it worked well.”

SightCity also featured .lumen in a dedicated post, highlighting how the Glasses use cameras, AI, and haptic feedback to guide blind users independently, without a guide dog, internet connection, or cloud processing.

For those who want a deeper look at the technology, Cornel Amariei also joined Christian Stahlberg on the Sightviews podcast, in the episode “Vibration statt Waldi: wie dotLumen blinde Menschen navigiert.” 

The conversation explains how the system works, why .lumen was founded, and includes a short hands-on test directly from our booth at SightCity. The Sightviews episode also describes .lumen as one of the most-discussed exhibits of SightCity 2026 and explains the device’s six-camera, AI, and forehead-vibration guidance system.

What .lumen members went to SightCity

Our team in Frankfurt brought together the core perspectives behind .lumen: technology, vision, and market adoption.

1. Cornel Amariei, CEO & Founder, will share the story behind .lumen, the mission of building scalable mobility for blind and visually impaired people, and the company’s long-term vision.

2. Balazs Blenyesi, Chief Business Development Officer, will meet with partners, distributors, institutions, and organisations interested in bringing .lumen technology closer to the people who need it.

3. Robert Gutt, Head of Navigation, will be there to explain how the Glasses understand pedestrian environments and guide users through space.

Still wondering what are the .lumen Glasses?

The .lumen Glasses for the Blind are an AI-powered mobility headset designed to help blind and visually impaired people move more independently.

The easiest way to explain them is this: they replicate some of the mobility functions of a guide dog, using technology.

The Glasses scan the environment using cameras and AI, understand what is around the user, identify safe paths, and guide the person through haptic & audio feedback.

If the user needs to move slightly left, right, or continue forward, the haptic feedback guides them intuitively. Audio is used only for specific situations where extra information matters, such as crossings, stairs, or finding important objects.

The goal is not to replace the white cane, the guide dog, or years of orientation and mobility training. The goal is to add a new layer of assistance: one that can understand the environment in real time and help blind people navigate more confidently through complex pedestrian spaces.

Thank you to everyone who visited, tested, challenged, asked, and helped us learn. SightCity was an important step in preparing .lumen for Germany.
