Claim 11:
12. An augmented reality device comprising:
a head-mountable frame;
a radar system that generates first and second radar fingerprints of locations of real-world objects relative to the user at first and second times;
a visual system that includes:
a visual camera mounted to the frame to capture first and second visual images of the real-world objects;
a visual tracking module connected to the visual camera and storing first and second visual images at the first and second time intervals, respectively;
a visual mapping module connected to the visual tracking module and generating first and second visual maps of locations of real-world objects relative to the user based on the first and second visual images;
a map merge and optimization module that refines the locations of the first and second sets of fingerprints based on the first and second visual maps, respectively;
a rendering module to determine a desired position of a rendered object based on the first and second sets of fingerprints as refined by the map merge and optimization module;
an eyepiece secured to the frame; and
a projector secured to the frame and operable to convert data into light to generate the rendered object and displaying the rendered object in the desired position to the user through the eyepiece.
