We help blind and visually impaired people to navigate safely. OKO, our mobile application, is able to recognise the pedestrian traffic light by using the smartphone camera and our AI algorithm it is able to inform the user on the state of the pedestrian traffic light. We bring this information back to the user using audio and haptic feedback.

In the future OKO will become smarter and will be able to do much more, like detecting obstacles, incorporating GPS navigation such that blind and visually impaired people can explore new places safely. Check out the OKO campaign to see how you can help.

What users say

"I requested an APS for an intersection where I have to cross twice a week (in two directions, so 4 moments of uncertainty). I no longer see the need of installing a physical APS.

Luc (Belgium, OKO App)

"I think the app is extremely useful, especially in places or countries that don’t have traffic lights with built-in solutions for blind and visually impaired people.”

Gilberto (Portugal, OKO App)

"It’s just a super app and I feel much safer crossing at a traffic light.”

Mai-Li (Belgium, OKO App)

"Amazing initiative, love to help out improve the OKO app.”

Nicolas (Belgium, OKO Campaign)
