Abstract: A transfer-alignment system for a Head-Mounted Display (HMD), and a display coupled to the HMD, wherein the display is 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 (FoR), the system comprising: at least one first inertial sensor attached to the HMD and configured to acquire HMD's Inertial Readings Information (IRI); at least one second inertial sensor attached to the display and configured to acquire display's IRI; and a processor configured to: obtain the HMD's IRI, the display's IRI and the information indicating the HMD's position and/or orientation with respect to the FoR; continuously analyze movement information of the HMD and the display to determine relative orientation therebetween; and cause the display-processor to adjust the images to conform with respect to the FoR.

Abstract: Head mounted displays (HMD) and corresponding display methods are provided, which obtain, repeatedly, from a monitoring system of a vehicle and, a reference vector relating to the vehicle; display on the HMD a reference symbol that indicates the reference vector; and determine movements of a HMD symbology according to a spatial relation between a received user's line of sight (LOS) and the reference vector. For example, the vehicle may be an aircraft and the reference vector a flight path vector (FPV) received from the aircraft's avionics. The proposed HMD enhances the displayed information content while avoiding excessive movements of the symbology. The HMD's functional parameters may be pre-set or adapted according to user preference and flight stage characteristics. The reference symbol anchors most of the symbology, while minimal critical information may be moved along with the user's LOS, providing a clearer and more stable view through the HMD.
