1. A display assembly comprising:
a waveguide assembly configured to project image light towards an eyebox, wherein an amount of aberration in the image light is based in part on a movement of the waveguide assembly;
one or more movement sensors coupled to the waveguide assembly, the one or more movement sensors configured to monitor the movement of the waveguide assembly; and
a display controller configured to correct for the amount of aberration in the image light based in part on the monitored movement.
