Intuitive and easy to use application

You can easily open the application by calling 'Hey Siri, open OKO'. There are no actions required the application immediately starts looking for traffic signal. The moment OKO detects a pedestrian traffic signal we bring that state back using audio, vibrations and visual overlay.

OKO, stops you from veering off

OKO reacts instantaneously this helps orient the phone in the right direction and provides an extra sense of orientation. The moment OKO starts providing feedback you intuitively know this is the direction I want to go. Once you start veering off into traffic OKO becomes silent, you reorient and OKO informs you immediately once you are back in the right direction.

How to properly use the OKO applicaiton

We usually recommend our users to hold the phone against the chest with the camera towards the direction you want to cross. Some people use a lanyard case to let the phone hang loose. Users then rotate the chest 10 to 15 degrees, the moment the OKO application sees a traffic signal it instantly brings back that information to the user. This also indicates to the user that his chest is now facing the right direction to cross hence avoiding directional confusion.
