OKO is a smart camera app designed to assist blind and visually impaired users in navigating their surroundings. This innovative app provides real-time feedback and helps users determine the state of pedestrian traffic lights.

By using haptic and audio feedback, OKO informs users about the status of pedestrian lights at intersections, similar to a physical APS (Accessible Pedestrian Signal) system. The app is developed in close collaboration with blind and visually impaired individuals, ensuring its effectiveness and usability.

Privacy is a top priority for OKO, as all data processed through the app remains on the user's device unless they choose to share it for improving the application and removing false positive detections. The app offers an option to anonymously share detected images with the developers for this purpose.

Please note that OKO works best in good weather conditions during daylight and can only provide information when the pedestrian traffic light is visible and unobstructed.
