1. An apparatus for processing absolute pose data derived from an absolute pose of a manipulated object in a real three-dimensional environment, said apparatus comprising: a) at least one invariant feature in said real three-dimensional environment; b) an optical measuring means for optically inferring said absolute pose from on-board said manipulated object using said at least one invariant feature and expressing said inferred absolute pose with absolute pose data (φ,θ,ψ,x,y,z) representing Euler rotated object coordinates expressed in world coordinates (X o ,Y o ,Z o ) with respect to a reference location; c) a processor for preparing said absolute pose data and identifying a subset of said absolute pose data; and d) a communication link for transmitting said subset to an application.
