OFFLINE-HongKong AR Navigation is a free Android application developed by Walter Hsieh in the Travel & Navigation category. This app uses the GPS and camera of your smartphone to provide an augmented reality-powered car navigation system. Unlike traditional navigation systems, this app guides the driver directly with a virtual path shown through the camera preview video, making it intuitive and easy to understand.

One of the most significant advantages of using this system is that the driver does not need to map the path or road. The driver can watch the real-time camera preview navigation screen to get driving conditions without impacting driving safety. This app is currently available for use in Hong Kong.
