Synthesis Of Sign Language Based On Opengl And Institutions

The use of hand gestures has become an important part of human computer interaction(HCI)in recent years.Hand gestures play a natural and intuitive communication mode for all human dialogs.The ability for computer to visually recognize hand gestures is essential for future human computer interaction. It involves several fields such as Pattern Recognition.lmage Process,Psychology and Cognitive Science,Computer Graphology,Robot Motion and Physics. The Research of Gesture-Language can be applied in many fields such as Computer Access Gesture-Language Teaching.TV Bilingual Broadcasting,the search of Virtual Human,the communication between the deaf and the normal, the control of VR.the study of robot.Sign language appears to be the main means of communication within the deaf community.ln spite of a repression cycle it has suffered from in several countries until recent past.it remains a living language.Our project of synthesizing sign language is based on the established facts that half of deaf people encounter difficulties in reading and ,as a result.suffer from subeducation.Being able to synthesize their mother tongue would undoubtedly be of major interest for those persons.From sign features edition to virtual animation,here are laid the foundations of a new interface intended for deaf people.In this paper,stress is laid on the solution of hand kinematic and revease kinematic.In the first place, we put forward the 3-link plane mechanism model of the finger and decomposition method for kinematic synthesis and analysis is introduced.This is accomplished by solving sets of equations which can be used to describe mathematical models of all 3-link plane or spatial mechanisms.sequentially and in an organized way. Fixed length of joint bring us much convenient in finding the solution of these equations. Problems associated with the simultaneous solutions of a multitude of linear and nonlinear equations are thus avoided. The paper introduces Denavit-Hartenberg matrix in robotics to synthesize the finger language, and also detrudes a kinematic and reverse kinematic function to simplify the fingermovement process. Experiment results show that it is reliable and effective. The method is also applicable to address the more complex a kinematic and reverse kinematic function of finger movement, which can effectively synthesize the finger language.Briefly.the decomposition method which has already been applied to the analysis and synthesis of 4,5 and 6-link mechanisms essential creates a general mathematical model for all the 42 types of 7-link spatial mechanism if we consider wrist.elbow and shoulder.The computer program for the solutions realized by OPENGL technology. OpenGL is the premier environment for developing portable, interactive 2D and 3D graphics applications. Since its introduction in 1992, OpenGL has become the industry's most widely used and supported 2D and 3D graphics application programming interface (API), bringing thousands of applications to a wide variety of computer platforms.The focal point of this paper in using OPENGL is how to move or rotate around a flexible axis. glRotatef(Angle,Xvector,Yvector,Zvector) is responsible for rotating the object around an axis.The crux of the matter is continuous axis-changing.
