A method and system for providing an optical see-through Augmented Reality modified-scale
display. This aspect includes a sensor suite 100 which includes a compass
102, an inertial measuring unit 104, and a video camera 106
for precise measurement of a user's current orientation and angular rotation rate.
A sensor fusion module 108 may be included to produce a unified estimate
of the user's angular rotation rate and current orientation to be provided to an
orientation and rate estimate module 120. The orientation and rate estimate
module 120 operates in a static or dynamic (prediction) mode. A render module
140 receives an orientation; and the render module 140 uses the orientation,
a position from a position measuring system 142, and data from a database
144 to render graphic images of an object in their correct orientations
and positions in an optical display 150.
