A method and system for three-dimensional topographical modeling. A control
surface that is adjustable provides a tactile-detectable graphical
representation of a three-dimensional graphical image and associated
physical characteristics. A sensitivity element detects an external force
applied to the control surface. A controller adjusts the
tactile-detectable graphical representation to model the associated
physical characteristics of the three-dimensional graphical image when
external force is applied to the control surface.
