Abstract
In this chapter, an enhanced methodology for interactive, accurate, fast and robust multibody simulations using Augmented Reality is presented and discussed. This methodology is based on the integration of a mechanical tracker and a dedicated impulse based solver. The use of the mechanical tracker for the interaction between the user and the simulation allows to separate the processing of the data coming from the position tracking from those coming from the image collimation processing. By this way simulation results and visualization remain separated and the precision is enhanced. The use of a dedicated sequential impulse solver allows a quick and stable simulation also for a large number of bodies and overabundant constraints. The final result of this work is a software tool able to manage real time dynamic simulations and update the augmented scene accordingly. The robustness and the reliability of the system will be checked over two test cases: a ten pendula dynamic system and of a cross-lift mechanism simulation.
