摘要:
A virtual reality flight control system displays to the pilot the image of a scene surrounding a vehicle or pod having six degrees of freedom of acceleration or velocity control by the pilot and traveling through inertial space, the image itself including a superimposed figure providing the pilot an instant reference of orientation consisting of superimposed sets of geometric figures whose relative orientations provide the pilot an instantaneous feel or sense of orientation changes with respect to some fixed coordinate system. They include a first set of geometric figures whose orientations are fixed to the pilot's vehicle and a second set of geometric figures whose orientations are fixed with respect to a fixed or interstellar coordinate system. The first set of figures is a first set of orthogonal great circles about the three orthogonal axes of the flight vehicle or pod and centered at and surrounding the pilot's head, while the second set of figures is a second set of orthogonal great circles about the three orthogonal axes of a fixed or interstellar coordinate system, also centered at and surrounding the pilot's head.

A system for generating and processing synthetic and absolute real time remote environments for interaction with a user and her biological senses is comprised of seven modules. These modules store, retrieve and process data to generate an output which interfaces with the system user's biological senses. These modules also track user data to accurately place the user in the generated and processed model. Various embodiments of the system user sensory interface are provided including visual and aural input devices and a three dimensional chamber having interactive tactile output via matrix-addressed, electromechanically operated rods driving a flexible skin.

A panoramic image based virtual reality display system includes a panoramic optical assembly, preferably of substantially spherical coverage, feeding composite optical images to a light sensitive surface of a video camera for storage or further processing in image processing circuitry. Such image processing circuitry includes a special effects generator and image segment circuitry to divide a composite image into a plurality of image segments or sub-segments for display on individual displays of multiple video display assemblies. Such a multiple video display assembly preferably includes a closed structure having individual display units mounted in all viewable directions therein, with segments of the composite image displayed on respective display units to recreate the panoramic view gathered by the panoramic optical assembly. The image processing circuitry may also select a portion or portions of the composite image for display on one or two displays of a head mounted display unit.

Visual system (37) for providing high detail, high resolution imagery anywhere a trainee is looking throughout a wide field of view. An image generation system (38) of visual system (37) accepts inputs from a helmet mounted oculometer system (30) which determines a trainee's instantaneous eye line-of-sight. The image generation system (38) provides a foveal view of high detail, high resolution imagery at the eye line-of-sight. The foveal view is projected on a screen (46) by a foveal projection system (40). The image generation system (38) further provides a peripheral view of low detail, low resolution imagery that is projected on screen (46) by a peripheral projection system (42). The foveal view is merged with the peripheral view by a merge electronics system (44).
摘要:
A video display system employs a plurality of controlled cathode ray tubes producing individual images which are combined by dichroic prisms to form a single image which is transmitted by a fiber-optic cable to a set of optical elements which transmit the image to the viewer. The position and orientation of the viewing instrument are sensed to provide control signals to an image generator to provide an image appropriate to the orientation of the viewing instrument.

An articulated light guide having internal mirrors and rotatable joints, vides a transmission path to a helmet mounted projector wherefrom light is transmitted onto a retroreflective screen to produce images utilized in simulation training. Located at the screen are photodiodes which detect the orientation of said images with respect to a reference and provide alignment signals to a servo-controlled image rotation device.
摘要:
Optical probe (21) for simultaneously providing two images along independent lines-of-sight that correspond to front and side views in a single camera model visual system. An optical probe comprises a first pitch prism (24) and a second pitch prism (28). The pitch prisms have respective first and second apparent entrance pupils that are external to each prism and common to both prisms at a particular location (32). All motion of the optical probe is constrained to rotations about the location (32) of the first and second apparent entrance pupils.
摘要:
A wide angle infinity display system to be utilized by a trainee pilot forbserving a visual scene displayed upon a retroreflective screen. The system includes a helmet adapted to be worn by the trainee pilot, image producing means for generating visual information, image forming means mounted upon the helmet for projecting the visual information onto the retroreflective screen so as to form the visual scene observed by the trainee pilot, and communicating means for transmitting the visual information from the image producing means to the image forming means. Position monitoring means coupled to the helmet sense angular movement of the head of the trainee pilot, and the visual scene is changed correspondingly, to permit scanning of a wide angle field of view.
