1. A method for displaying, at a display interface coupled to a processor, position and motion information among objects in three-dimensional space, comprising the processor-controlled steps of:
- generating and displaying at the interface a parallel coordinate plane having a plurality of axes, including a velocity axis and, orthogonal thereto, four parallel coordinate axes comprising three axes representing spatial dimensions and one axis representing a temporal dimension; and
displaying on said parallel coordinate plane a plurality of multi-segmented lines, each multi-segmented line forming a unique representation of the position and motion information of one of said objects so that separation between said multi-segmented lines in one of said parallel coordinates can be detected as indicative of a lack of a conflict between the positions of the objects.

Abstract
Critical differences in the position and motion of aircraft in congested N-dimensional airspace are highly discernible when processed and mapped onto a parallel N-coordinate plane. Trajectory intersection in both time and space may be constantly monitored. The airspace may be accurately controlled by descriptively and prescriptively configuring proposed trajectories and monitoring critical differences before assignment to aircraft. Attributes such as angular deviation, in addition to closing speed and distance, can be evaluated.

5. A method of displaying the trajectories of first and second aircraft through three dimensional space, comprising:
-
generating in a processor and displaying at a user interface a parallel coordinate plane having a plurality of axes, including a velocity axis and, orthogonal thereto, four parallel coordinate axes including three axes representing spatial dimensions and one axis representing a temporal dimension; generating in said processor and displaying on said parallel coordinate plane first and second multi-segmented lines, each line representing a unique set of points representing the position and motion information of a respective one of said aircraft; and determining whether separation exists between said multi-segmented lines in at least one of said parallel coordinates to determine whether a conflict exists between the trajectories of the first and second aircraft. - View Dependent Claims (6)

7. A method of determining potential conflict between two N-dimensional processes comprising:
-
generating in a processor and displaying at an interface an N-axes parallel coordinate plane having N parallel axes, each representative of one of said N dimensions; generating in said processor and displaying at said interface on said paralel coordinate plane a first polygonal line representing a first N-tuple, said first N-tuple being a multivariate data point of a first process, and said first polygonal line intersecting each of said parallel coordinates; generating in said processor and displaying at said interface on said parallel coordinate plane a second polygonal line representing a second N-tuple, said second N-tuple being a multivariate data point in a second process, said second polygonal line intersecting each of said parallel coordinates; determining if a predetermined relationship exists between said first and second polygonal lines at any of said parallel coordinates. - View Dependent Claims (8, 9, 10, 11)
