Three-Dimensional Force Display System Based on the Interpolation of Measured Data

Abstract

Measuring the force feedback from the object, describing it in virtual space, and displaying it in real time are necessary for the purpose of displaying the three-dimensional (3D) force feedback from a real object. We have constructed a system realizing these procedures. In the system, 3D force feedback from an object is described by interpolating measured data using Radial Basis Function (RBF). Real-time force display is carried out by direct access of a set of grid points sampled from the interpolated force field.
