Modeling systems are enhanced by combining physical and virtual modeling
techniques to create a hybrid modeling system. Manipulation of physical
models results in updated real-time physical characteristics being
provided to a virtual model. User manipulation of virtual model
characteristics can also be provided and implemented on the physical
model using actuators and control devices. The invention also enables
multiple users to simultaneously construct and manipulate different
portions of a physical model, e.g., of an atom or a molecule, and to have
the results of these manipulations provided to a computer system for
computational analysis. The results of such analyses can be
electronically returned to the physical model, e.g., wirelessly.
