A Mathematical Model for Hand-Shape Analysis
A mathematical model of the human hand is presented. It models both the physical form and kinematic constraints of the fingers. An algorithm that takes as input six 3-dimensional coordinates, corresponding to the wrist and fingertip positions, and produces a geometric model of the hand is discussed. This algorithm uses the previously mentioned mathematical model. Results from an implementation of this algorithm are presented and discussed. The results show that fairly accurate geometric models of various hand-shapes can be produced very quickly using this algorithm. Critical analysis of the model and algorithm is undertaken and improvements suggested.
