A real-time gesture recognizer based on dynamic programming

摘要: Coded gestures are physical movements to which precise meanings have been attached. Their use with an electronic pointing device potentially increases the power of pointer by allowing several distinct control functions be incorporated. The formation a coded gesture is invariably subject distortions make its automatic recognition difficult. After particular consideration three techniques, dynamic programming algorithm was developed and used in design real-time recognizer that allows mouse-driven software operated purely means pointer. decision taken implement using widely available, obsolescent microcomputer order keep down costs. Despite inevitable technical compromises this approach, results preliminary trials 10 normal subjects show average rate 98.3% confusion only 0.4%.
