Claim 0:
1. A system for displaying layers of synthetic vision system (SVS) data as a function of a line of sight (LOS) designation of a user within an aircraft, the system comprising:
a multilayered database comprising a scene representation of a real-world scene and multiple data layers each comprising display data regarding the terrain and/or obstacles in the real-world scene, wherein the multiple data layers are each conformal to the scene representation of the real-world,
wherein the scene representation is associated with a view through a three-dimensional see-through display, having a depth dimension and a planar dimension, which is used by a user, and
a control unit comprising a line of sight (LOS) tracker configured to track the user's LOS with respect to the real-world scene, or track the user's LOS relative to the aircraft and convert to LOS relative to the real-world scene,
wherein the control unit is configured to identify a region of interest (ROI) in the scene representation at which the user's LOS is aimed, and to display, via a display control and on the three-dimensional see-through display, the multiple data layers,
wherein the control unit is further configured to select among the multiple data layers according to the ROI and:
attenuate one or more of the multiple data layers, or a part thereof, relative to a remainder of the multiple data layers according to a respective distance thereof in three dimensions from the ROI by varying visual parameters to reduce a prominence of the display data on the attenuated one or more of the multiple data layers, and
enhance one or more of the multiple data layers, or a part thereof, relative to a remainder of the multiple data layers according to a respective distance thereof in three dimensions from the ROI by varying visual parameters to increase a prominence of the display data on the enhanced one or more of the multiple data layers.
