Method for the display of navigation instructions using an augmented-reality concept
First Claim
1. A method for the display of navigation instructions, which have been generated as a function of a user defined destination, whereby the current position of the user is recorded using GNSS satellite systems, the orientation of the user is established through azimuth information from a GNSS sensor and a digital compass, the field of view in front of a user is recorded by a video camera and the video image is augmented for navigation by superimposing navigation instructions assembled using the output data from said sensors.

Abstract
A method with which navigation instructions are displayed on a screen. Preferably, using an augmented-reality approach whereby the path to the destination and 3D mapping objects such as buildings and landmarks are highlighted on a video feed of the surrounding environment ahead of the user. The invention is designed to run within embodiments the likes of Personal Digital Assistants (PDAs), smartphones or in-dash vehicle infotainment systems, displaying in real-time a video feed of the path ahead while superimposing transparent cartographic information with navigation instructions. The aim is to improve the user'"'"'s navigation experience by making it easier to relate to the real world with 3D maps and representative navigation instructions. This method makes it safer to view the navigation screen and the user can locate landmarks, narrow streets and the final destination more easily.
