VimAI's computer vision based positioning uses the camera feed of a mobile phone to identify the location and viewing direction of the user. That enables converting buildings of any size to shared AR experiences. The system allows such wide-area AR applications as navigation and contextual virtual content visualisation in buildings like industrial plants, shopping malls, museums, conference centers, hospitals, airports and hotels. The virtual content is visible to all users at the same place at the same time allowing sharing of the experience. The interactions can also be shared opening up opportunities for multi-user collaboration.
