Improvements in or relating to Visual Display Apparatus Abstract The invention provides head-coupled area-of-interest visual display apparatus particularly for ground-based craft-flight simulators. An image generator of the computer generated image type is used. Line scanning apparatus is cockpit-mounted; transmission of line image is by fibre optic guide ribbon and frame scan apparatus is helmet-mounted. Sensing means detect head/helmet movement to permit voluntary scanning of a wide angle of simulated view from the craft. Due to the projection mount having the capability of continuous rotation, with the image being computed for discrete angular positions only, together with the computational throughput delay in the image computer, the new image, after head/helmet rotation, is momentarily delayed after the new line of vision is established. Means are provided to de-rotate the projected image to its former position on the screen until such time as the modified image is available. P.2097/1
