- Metrics and Models for the
Perceptual Design of Virtual Transparency - Progress (09/98~10/98)
The ATC Tower simulation is being rewritten
to accept CTAS-like data records for ultimate connection to live
air traffic data. The expanded spatial calibration data have
been verified by remeasurement after implementation of the distortion
correction. Generally, the system provides sub centimeter accuracy,
with the largest errors associated with the less frequently used
extreme positions near the walls.
