About EBITH
EBITH — Even Blind I Am The Hero — is an assistive technology platform from Devs And Visuals. It exists because the tools that help visually impaired and deaf people navigate and communicate are still priced like medical equipment and built like laboratory experiments.
Around 2 million people in the UK are deaf or have significant hearing loss, and roughly 340,000 are registered blind or partially sighted. The technology that would give them day-to-day independence exists. It is just locked behind £2,500–£6,000 devices, cloud subscriptions, and models trained on the wrong sign language.
EBITH puts three of those capabilities — obstacle and signage detection, British Sign Language recognition, and two-way speech-to-text communication — into an app that runs on a phone someone already owns, offline, for free at the point of use.
We are not trying to replace interpreters, guide dogs, or long canes. We are trying to cover the hours of the day when none of those are available: the unfamiliar street, the GP waiting room, the classroom conversation happening two desks away.
The measure of success is not accuracy on a test set. It is whether someone gets somewhere they would not otherwise have gone.
How We Work
Every model EBITH ships runs on the device. Camera frames, audio, and sign sequences are processed locally and discarded. There is no upload endpoint to secure, because there is no upload.
A 255 KB model on a mid-range Android phone is not a compromise on a cloud model — it is the thing that makes the product usable on a bus, in a hospital corridor, in a classroom with no Wi-Fi.
Assistive technology built without disabled people in the room becomes a demo. We validate every feature against real BSL users and cane users before it ships, not after.
The Team
Devs And Visuals is a small product engineering studio. EBITH is our own product, not client work — which means we answer to the people who use it rather than to a roadmap someone else set.
The work spans four disciplines: applied machine learning (sequence models, landmark extraction, on-device quantisation), mobile engineering (Flutter, TFLite, camera pipelines), accessibility research (BSL linguistics, WCAG conformance, voice-first interaction), and design.
We are currently pursuing UK Innovate UK grant funding, US NSF accessibility programmes, and NHS innovation partnerships to fund the 2025–2026 pilot programme with three UK special needs schools.
This site targets WCAG 2.1 Level AA. In practice that means: every interactive element is reachable and operable by keyboard with a visible teal focus ring; body text meets a 4.5:1 contrast ratio and large text 3:1; all decorative animation is hidden from assistive technology and disabled entirely when your system requests reduced motion; no information is carried by colour alone; and page structure uses real landmarks and a single logical heading order.
The hero animation is decorative but meaningful, so it carries a text description for screen reader users rather than being silently hidden.
If any part of this site is difficult to use with your assistive technology, that is a defect and we want to hear about it. Email hello@devsandvisuals.com and we will fix it.
This website sets no advertising or tracking cookies and runs no third-party analytics. Nothing you do here is profiled or sold. Standard server logs, retained by our host for operational security, are the only record of a visit.
The EBITH app processes camera frames, audio, and sign sequences entirely on your device. None of it is transmitted, stored remotely, or used for training. Recognition happens inside a 255 KB TFLite model that works with the network switched off.
If you email us, we keep your message and address only as long as needed to answer you and to maintain a record of grant and partnership correspondence. Ask us to delete it and we will.
