Abstract: A system for displaying a combined image data from several sources on a head-mounted see-through display (HMSTD) defining a line of sight (LOS) is provided herein. The system includes: a tracker configured to track the LOS of the HMSTD; a display controller configured to display a first display area including a synthetic image data conformal to a scene viewed via the HMSTD; a trigger mechanism configured to select a desired point within the scene which intersects the LOS of the HMSTD at a time of a triggering event, wherein the display controller is configured to receive the desired point and to display a second display area on the HMSTD, wherein the second display area is positioned relative to the desired point, and wherein said display controller is further configured to modify the synthetic image data in a portion of the first display area covered by the second display area.

Abstract: A method for initiating a gesture-based mutual interaction scheme between a first and second mobile device, comprising: associating a gesture-based mutual interaction scheme between the first and second mobile device that associates a position scheme with a respective action, where the position scheme relates to any of: an absolute or relative orientation, and an absolute or relative trajectory; acquiring a first position property of the first mobile device and a second position property of the second mobile device; determining that each of the first and second position properties comply with the position scheme; triggering an execution of an action on the second mobile device, where the action is associated with the position scheme that the first position property complies with; where the second mobile device conditions the execution of the action triggered by the first mobile device on the compliance of the second position property with the position scheme.

Abstract: Optical systems and methods are provided, which combine see-through view of the real world and display source images using a conical optical combiner cut to have flat surfaces normal to the viewer line of sight. The conical shape minimizes interferences in the view of the real world as the edges of the optical combiner are tangent to the viewer vision field of view and the inner part of the optical combiner is semitransparent. Additionally, the optical system comprises a beam splitter, a shutter(s) for attenuating or blocking the see-through path and may employ polarizing element to improve the contrast between the scene observation and the projected display and thus enabling selective viewing of either. The system may also be configured to enable diopter adjustment and virtual display distance adjustments.

Abstract: Method for verifying registration of a model of an internal-body-part with the internal-body-part in a reference coordinate system. The internal-body-part is at least partially unseen directly by a user. The method includes the procedures of continuously determining a position and orientation of a head-mounted-display in the reference coordinate system, determining a display location of at least one virtual marker, and displaying the virtual marker according to the display location. The display location of the virtual marker is determined according to the expected position of a respective at least one reference point relative to the head-mounted-display. The reference point is directly visible to the user. The relative position between the reference point and the internal-body-part is substantially constant. The position of the reference point in the reference coordinate system is predetermined. When the model and the internal-body-part are effectively registered, the reference point and corresponding virtual marker appears visually in alignment.

Abstract: Embodiments concern a method for providing information to a user of a vehicle via a display device that is worn by the user. The method comprises providing a principle axes rotation coordinate system (Vxyz) that defines a vehicle orientation relative to a world coordinate system (Wxyz) of a reference world space; providing at least one display device coordinate system (Dxyz) that defines a display device orientation relative to the vehicle coordinate system; and providing a symbol coordinate system (Sxyz) that is spatially fixed with at least one first symbol to be displayed on the display device and that defines three symbol rotation axes that are orthogonal to each other; and spatially fixing at least one of the symbol rotation axes (Sα) to a vehicle principal axis of rotation descriptive of an orientation of the vehicle.

Abstract: A system for monitoring a pilot's health is provided herein. The system may include: a head mounted device mountable to a head of a pilot; at least one vital signs sensor couplable to a body portion of said pilot and configured to obtain vital signs data associated with said pilot; at least one head sensor configured to obtain head-related data associated with the head of said pilot; and a computer processor configured to receive the vital signs data and the head-related data as an input and generate as an output, an indication of pilot incompetence, based on predefined criteria.

Abstract: Head-mounted see-through displays and methods are provided which improve helicopter displays and provide more relevant information to the pilot while reducing the information load on the display. Displays comprise a peripheral pilot-scene pitch indication region, indicating scene orientation information according to an orientation of the pilot's head with respect to the scene, a propulsion state indication region, indicating rotor and engines states with respect to their nominal operation states by presenting only deviations of the rotor and engines states from their nominal operation states, a speed indication region, indicating, in association with displayed air speed, a calculated ground speed or a calculated ground speed component in a direction of propagation and a helicopter pitch indication region displaying a pitch ladder which is re-arranged to space close pitch lines and crowd remote pitch lines.

Abstract: A novel surgical lens system including a lens and a reflective element. The lens is placed on, or above, a cornea of an eye of a subject for enabling inspection of the eye. The reflective element is incorporated into the lens. The reflective element reflects a light beam toward the eye of the subject. The reflective element increases the divergence of the light beam, such that the divergence of the reflected light beam is larger than the divergence of the light beam. The light beam is emitted by a non-invasive light source positioned externally to the eye.
