We present a method for enhanced 3-D tracking using an interaction matrix. We developed two constraints to avoid the singularities and local minima of the interaction matrix. These constraints were combined with the minimization of tracking errors to identify suitable system configurations for enhanced tracking. Experiments were conducted to validate the method. © 2006 Society of Photo-Optical Instrumentation Engineers.
