Display relative motion compensation

1. A method for displaying an image via a display device worn on a head of a user, the display device including one or more sensors, the method comprising:

displaying the image at an initial registration position with respect to an eye of the user;

receiving 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;

filtering the composite motion data to remove the head motion component and yield the relative motion component;

using the relative motion component, adjusting 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;

displaying the image at the adjusted registration position by projecting the image onto a cornea of the eye;

at a stabilization frequency, performing subsequent adjustments of image registration positions using relative motion components;

displaying 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, performing centering adjustments of image registration positions that progressively locate the image closer to a reference location on the cornea; and

displaying the image at adjusted registration positions corresponding to the centering adjustments of the image registration positions.

2. The method of claim 1 , wherein the one or more sensors comprise two accelerometers.

3. The method of claim 1 , wherein the one or more sensors comprise an optical sensor.

9. The method of claim 1 , further comprising:

receiving companion sensor data from a companion device; and

using the companion sensor data, adjusting the initial registration position of the image to compensate for the relative motion component.
