VISTAS III
The Visual Imaging Simulator for Transport Aircraft Systems (VISTAS)-III
is a part-task visual flight simulator/workstation that uses
Commercial-Off-The-Shelf rear-screen projectors to replicate a pilot's
visual surroundings from the cockpit of a typical large transport
aircraft. By projecting the out-the-window or "heads-up" displays and
the instrument panel or "heads-down" displays, moving images can be
displayed simultaneously on seven screens. This capability creates an
ideal environment for rapid-prototyping, development, and preliminary
evaluation of cockpit display concepts, such as a real-time,
computer-generated view known as "Synthetic Vision."

The single pilot fixed-based workstation consists of a 144 degree by 30
degree out-the-window visual, a simulated HUD, a large field,
reconfigurable screen for head-down displays, and pilot input controls.
Rudimentary pilot controls are provided, including a left side-stick
controller, center-aisle throttle controls with take-off/go-around
(TOGA) button, rudder pedals, toe brakes, landing gear switch and a
Personal Computer (PC) track ball for display-related cursory-control
pilot inputs. A speaker-independent voice recognition system is
installed as a robust, rapidly-reconfigurable pilot-vehicle interface.
Further, a speech-generation capability provides automated alerts,
warnings, and simulated Air Traffic Control commands.
VISTAS-3 also includes the capability to perform Helmet-Mounted Display
(HMD) research. The retinal scanning HMD provides a full-color,
fully-overlapped binocular, high-resolution (1280x1024 pixels) display
over a 41o Horizontal x 33o Vertical field-of-view. The HMD provides a
high-bright display with over 60% transmissivity. The HMD can generate
both virtual and augmented reality display concepts.

The HMD is driven from PC-based graphics generators which minimizes
display concept development time. Coupled with an optical head-tracker,
this system provides a research platform for unlimited field-of-regard
cockpit display applications, stereo display development, and augmented
reality concepts.
