In this paper, we use the natural neighbor coordinates and its properties as a tool for electromagnetic tracker calibration. We have established a framework for computing the three-dimensional natural neighbor coordinates and used it for the calibration process for which we wish to eliminate the distortion error presented in the electromagnetic field. Our work comprises of two main parts. The first is about the computational model of the natural neighbor coordinates while the second is a discussion on the result we get after calibrating the electromagnetic tracker distortion. Our result has shown that the natural neighbor coordinates can be a promising method for approximating the distortion in the electromagnetic field and for calibrating the distorted field data.
