AR display device for vehicle and method for operating same

An augmented reality, AR, display device for a vehicle comprising:

• a communication module configured to receive image data including a front image of the vehicle, location data including a current location of the vehicle, map data relating to the current location of the vehicle, state data of the vehicle, and network data obtained from an external resource;
• a processor configured to activate a preset application to render an AR graphic interface overlapping the front image, the AR graphic interface including a first AR object indicating a current driving state of the vehicle and a second AR object indicating a guide for driving based on the current location of the vehicle and the map data;
• and
• a display configured to display a navigation screen including the front image overlapped by the AR graphic interface according to the rendering,
• wherein the processor is further configured to:
• predict a context to occur based on the state data of the vehicle and the network data, and
• update the AR graphic interface based on the prediction in a manner of separating the second AR object from the first AR object to a location associated with an occurrence of the predicted context while the first AR object keeps being displayed and changing the separated second AR object into driving guide information related to the predicted context,
• wherein the driving guide information includes additional information related to the predicted context, and
• join the second AR object to the first AR object when the predicted context is determined to have ended.
