Methods and systems are provided for using a user's line of sight (LOS) and/or gaze direction to enhance displayed data and control various displays and instruments. The user's LOS is tracked, corresponding element(s) in a scene at which the user gazes are identified, e.g., in a database, and respective displayed data are enhanced or otherwise manipulated with respect to the identified element(s). The database may be multilayered and may comprise data layers which are conformal to a scene representation. Users may also select, using their LOS, among multiple layers of information and among multiple displayed parts to enhance or attenuate respective layers or parts. Designated elements may be real-world elements, displayed elements or instruments in the operational surroundings of the user. Identification of elements at which LOSs of multiple users are aimed at may be used for exchange of information among the users.

The optical system may include an electronic display; and a light directing medium configured to steer a plurality of viewing cones into an eye motion box facing said display so that said viewing cones overlap at least partially at the eye motion box plane, wherein a viewing cone is a geometric location only within which a viewer can see light coming from said electronic display.

Aspects of embodiments pertain to a display illumination optics for illuminating an image display device of an image generation apparatus, the display illumination optics comprising: a source illumination distributor that includes an illumination waveguide having a front surface and a back surface opposite the front surface and configured to internally direct light along a main direction, wherein the illumination waveguide is configured to distribute the luminance of input illumination light along the main direction of the display illumination optics to obtain, along the main direction, output illumination light of desired luminance.

A method and a system are provided herein for calculating whether or not a specific aerial vehicle at a specified point of time can maneuver over a given location in the terrain while complying with terrain clearance requirements. The system may include a computer memory configured to store a 3D model representing at least a portion of a terrain located in a vicinity of an aerial vehicle; a computer processor configured to map said portion of the terrain into at least two types: a first type indicative of a potential of the aerial vehicle to maneuver over a respective terrain while complying with terrain clearance, and a second type indicative of a non-potential of said aerial vehicle to maneuver over a respective terrain, wherein the mapping is carried out based on said parameters, the 3D model and given predefined performance of the aerial vehicle.

A mixed A mixed reality system, comprising: a sensor configured to acquire readings of real-world data, and display, on an output device, a real-world visualization of the real-world data based on the readings to a user, wherein the sensor has one or more parameters affecting the real-world visualization; and a processing circuitry configured to: obtain (a) information of one or more virtual entities located within an area from which the readings are acquired, the information defining, for each of the virtual entities, one or more simulated physical properties, and (b) values of one or more situational parameters indicative of a state of the sensor during acquisition of the readings, wherein the values of the one or more situational parameters are readings of one or more situational sensors, sensing the state of the sensor and its surroundings during acquisition of the readings; determine, for at least one given virtual entity of the virtual entities, a virtual entity visualization of the given virtual entity, the virtual entity visualization determined by manipulating a simulated reading of the simulated physical properties based on (a) the parameters affecting the real-world visualization, and (b) the values of the situational parameters; and display the virtual entity visualizations in combination with the real-world visualization, thereby enabling a user viewing the output device to view the virtual entity visualizations and the real-world visualization.

A method and a system for displaying a scene to a user wearing ahead mounted display (HMD) while removing obstructions in a field of view (FOV) of the user are provided herein. The method may include: capturing by a sensor a vehicle image of the scene wherein the first sensor is mounted on the vehicle; tracking a position and orientation of the HMD in a specified coordinate system, to yield a line of sight (LOS) of the user wearing the HMD; obtaining a database containing obstacles data indicating at least one physical object located within the vehicle and affecting the FOV of the user; calculating an obstructed portion in the FOV of the user, based on the LOS and the database; generating from the vehicle image, an un-obstructed view which includes a portion of the scene overlapping the obstructed portion; and displaying in the HMD the un-obstructed view.

Imaging systems and methods are provided, which implement wide field imaging of a region for medical procedures and provide tracking of tools and tissues in the whole region while providing digitally magnified images of a portion of the captured region. Optical tracking may be implemented by stereoscopic imaging, and various elements may be optically tracked such as various markers and fiducials, as well as certain shapes and objects which are optically identifiable by image processing.

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.

A method and system for providing depth perception to a two-dimensional (2D) representation of a given three-dimensional (3D) object within a 2D non-visible spectrum image of a scene is provided. The method comprises: capturing the 2D non-visible spectrum image at a capture time, by at least one non-visible spectrum sensor; obtaining 3D data regarding the given 3D object independently of the 2D non-visible spectrum image; generating one or more depth cues based on the 3D data; applying the depth cues on the 2D representation to generate a depth perception image that provides the depth perception to the 2D representation; and displaying the depth perception image.

A mixed reality system, comprising: a data acquisition device configured to acquire real-world data; an output device for providing the real-world data to a user; and a processing circuitry configured to: obtain (a) data acquired by the data acquisition device, and (b) information of one or more virtual entities having properties enabling determination of simulated effects of the virtual entities on the data; determine the simulated effects of the virtual entities on the data utilizing the properties; and provide the user with output on the output device being a manipulation of the data reflecting the simulated effects.
