Display relative motion compensation

A display device configured to be worn on a head of a user and to display an image, the display device comprising:

• a computing device;
• one or more sensors communicatively coupled to the computing device;
• a display system configured to display the image at an initial registration position with respect to an eye of the user;
• and
• an image stabilization program stored in a mass storage of the computing device, the image stabilization program configured to:
• receive composite motion data from the one or more sensors, the composite motion data comprising a head motion component and a relative motion component which is relative motion between the head and the display device;
• filter the composite motion data to remove the head motion component and yield the relative motion component;
• using the relative motion component, adjust the initial registration position of the image to an adjusted registration position with respect to the eye of the user that compensates for the relative motion component;
• display the image at the adjusted registration position by projecting the image onto a cornea of the eye;
• at a stabilization frequency, perform subsequent adjustments of image registration positions using relative motion components;
• display the image at adjusted registration positions corresponding to the subsequent adjustments of the image registration positions;
• at a centering frequency that is slower than the stabilization frequency, perform centering adjustments of image registration positions that progressively locate the image closer to a reference location on the cornea;
• and
• display the image at adjusted registration positions corresponding to the centering adjustments of the image registration positions.
