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.

Abstract: System for determining a position of a tool-point-of-interest of a tool, relative to an eye-tissue-of-interest, which includes and imager a tool-tracker and a processor. The imager acquires an image of a tissue-reference-marker. The tool-tracker determines information relating to the P&O of the tool in a reference-coordinate-system. The imager and the tool-tracker are in registration with the reference-coordinate-system. The processor determines the position of the tissue-reference-marker in the reference-coordinate-system, according to the acquired image of the tissue-reference-marker. The processor determines the P&O of the eye-tissue-of-interest in the reference-coordinate-system according to at least the position of the tissue-reference-marker and a relative position between the tissue-reference-marker and the eye-tissue-of-interest. The relative position is pre-determined from a stored-3D-model. The processor determines the position of a tool-point-of-interest in the reference-coordinate-system from the P&O of the tool in the reference-coordinate-system. The processor also determines a relative position between the tool-point-of-interest and the eye-tissue-of-interest.
