Abstract
A piecewise progressive continuous calibration method with context coherence is utilized to improve display of virtual content. When a set of frames are rendered to depict a virtual image, the VAR system may identify a location of the virtual content in the frames. The system may convolve a test pattern at the location of the virtual content to generate a calibration frame. The calibration frame is inserted within the set of frames in a manner that is imperceptible to the user.
