Helmet Mounted Display Feasibility Model
Abstract
A feasibility model of an advanced visual display system for flight simulation is described. The feasibility model is comprised of a video projector mounted on a pilot's helmet which projects a computer generated image onto a spherical screen. The video projector utilizes a laser light source in forming the projected video raster. The display is slaved to the viewer's head pointing direction via a magnetic head tracking device, and results in imagery that is generated and displayed for the instantaneous viewing direction of the observer. Since the computer image generator requires a measurable period of time to create an image for a specific head pointing direction, an undesirable display orientation error is induced each time the viewer moves his head. A method of continuously compensating for this image display error was provided and is described. This feasibility model has demonstrated successfully, on a small scale, the helmet mounted display concept. This concept will be utilized in a full scale development model scheduled for delivery under contract in 1985. (Author)
