A system for predicting head movements by an aircrew member, such as a pilot flying a tactical aircraft, from input data which includes an ongoing record of head positions. The input is without head acceleration or velocity input data and is applied to a Least Mean Square prediction algorithm. The disclosure also includes an improved data dependent convergence algorithm for the prediction system, an algorithm shown to provide rapid convergence to the final prediction output. Use of the prediction system to make the delay between actually viewed and HMD presented images and other flight video images acceptable from a human engineering and disoriented pilot avoidance viewpoint is also disclosed. A computer program embodiment of the system using head movement data is included.
A weapon terminal that includes a sensor for sensing an orientation of the head of an operator of the weapon terminal, a heads-up display supported by the head of the weapon terminal operator for providing a display image viewable by the weapon terminal operator, a weapon terminal processor responsive to the sensing means and radar track reports for radar detected aircraft for controlling heads-up display to produce a display image that includes symbols representing the radar detected aircraft, wherein symbols are located at positions that represent the positions of the radar detected aircraft in relation to a direction in which weapon terminal operator is facing.
The invention is a method for displaying otherwise unseen objects and other data using augmented reality (the mixing of real view with computer generated imagery). The method uses a motorized camera mount that can report the position of a camera on that mount back to a computer. With knowledge of where the camera is looking, and the size of its field of view, the computer can precisely overlay computer-generated imagery onto the video image produced by the camera. The method may be used to present to a user such items as existing weather conditions, hazards, or other data, and presents this information to the user by combining the computer generated images with the user's real environment. These images are presented in such a way as to display relevant location and properties of the object to the system user. The primary intended applications are as navigation aids for air traffic controllers and pilots in training and operations, and use with emergency first responder training and operations to view and avoid/alleviate hazardous material situations, however the system can be used to display any imagery that needs to correspond to locations in the real world.
A helmet display system is provided comprising a display visor 3 located on helmet 1 on which helmet is also positioned image projection means for projecting an image via a holographic combiner 4 on the display visor 3. The helmet further comprises an anti-glare visor 2 which has optical transmission characteristics similar to those of a neutral density visor, with the exception that these characteristics are modified to compensate for the low transmission value of the display visor 3 to frequencies within a narrow waveband to which the combiner 4 is tuned. The invention provides a helmet display system which can be used in conjunction with an aircraft head-up display if required.
A device and method which operates as an artificial labyrinth to eliminate sensory mismatch between the natural labyrinth/vestibular system and the vision system of an individual. The present invention provides an alternative means for the user to determine the true orientation of his body with respect to the surrounding environment. The method can be effected by means of a device which senses true body orientation and displays corresponding visual orientation cues that the brain can use to confirm other visual position information. The display can be projected into space in front of the user, directly onto the user's retina, or effected by pictorial scene averaging. The device is particularly useful in the rehabilitation treatment of persons suffering from vestibular nervous system defect or damage, and in providing relief to those suffering from the symptoms of nausea and/or vertigo which are often experienced as a result of the aforementioned sensory mismatch.
A system for operator training and evaluation may detect and record information about various actions taken by an operator. For example, the system may record what the operator looks at in the course of operating the vehicle to determine whether the operator is looking at the things which the operator should appropriately be checking. In addition the system may provide other information about other aspects of the operator's performance including speed and use of controls and indicators. This information may be correlated and provided in the form of an evaluation. Alternatively, the operator may be prompted in the course of operating the vehicle to correct the operator's performance to improve the operator's skill.
