Classification: CPC G | IPC G

Claim 12:
13. A method of displaying rendered content comprising:
attaching a head-mountable frame to a head of a user;
executing a plurality of radar cycles to generate first and second radar fingerprints of locations of real-world objects relative to the user at first and second times in a slow domain;
detecting first and second measurement values at the first and second times in the slow domain, each measurement value being indicative of at least one of position and movement, with a measurement unit secured to the frame;
determining first and second pose estimates, the first pose estimate being based on the first set of radar fingerprints relative to the first measurement value and the second pose estimate being based on the second set of radar fingerprints relative to the second measurement value;
determining drift of the measurement unit by comparing the first pose estimate with the second pose estimate;
adjusting a measurement unit filter that is connected to the measurement unit to correct for the drift;
determining a desired position of a rendered object based on the second pose estimate;
converting data into light to generate the rendered object; and
displaying the rendered object in the desired position to the user through an eyepiece secured to the head-mountable frame.
