Route guidance method and device using augmented reality view
A method of obtaining a route from a point of departure to a destination includes providing route guidance through an augmented reality (AR) view including an image captured by a camera. To provide route guidance, as a user terminal moves toward a destination on the basis of an obtained route, when an interaction occurs between the user terminal and a node or a link in which predetermined information included in the route is registered, content associated with the predetermined information is augmented and displayed as guidance information on an image of an AR view.
