1. A transfer-alignment system for a Head-Mounted Display (HMD), and a display coupled to the HMD, wherein the display is (a) adjustable by a user along the at least one degree of freedom, and (b) adapted to display images rendered by a display-processor, and wherein the HMD is monitored by a tracking system configured to provide information indicating position and/or orientation of the HMD with respect to a frame of reference, the system comprising:
at least one first inertial sensor attached to the HMD and configured to acquire HMD's inertial readings information indicative of movements of the HMD over time;
at least one second inertial sensor attached to the display and configured to acquire display's inertial readings information indicative of movements of the display over time; and
a processor configured to:
obtain the HMD's inertial readings information, the display's inertial readings information and the information indicating the HMD's position and/or orientation with respect to the frame of reference;
continuously analyze movement information of the HMD and movement information of the display to determine relative orientation between the HMD and the display; and
cause the display-processor to adjust the images to conform with respect to the frame of reference based on the information indicating the position and/or orientation and the relative movements of the HMD, wherein the frame of reference is selected from the group consisting of a platform coordinates, a fixed coordinate system established in space, an earth coordinate system, and any combination thereof.
