基于VRML虚拟人的维文手语库的构建

CONSTRUCTION OF UIGHUR SIGN LANGUAGE DATABASE BASED ON VRML VIRTUAL HUMAN

维吾尔语的手语合成有助于改善维吾尔族聋哑人与听力正常人进行自然交流,也可以应用于计算机辅助维吾尔哑语教学、维文电视节目播放等方面。维文手语库是维吾尔语手语合成的基础。通过分析维吾尔手语的特点,采用关键帧插值技术来控制VRML虚拟人的手势动作,利用Visual C++和OpenGL环境实现了一个维吾尔文的手势编辑系统,通过手势运动数据驱动虚拟人来实时显示当前的手势状态。通过该系统,收集了常用的维吾尔语词汇及32个维吾尔字母的手势运动数据。

The synthesis of Uighur sign language can improve natural communication between Uighur deaf people and the normal ones.It can also be applied to computer-aided Uighur sign language teaching and Uighur television programs broadcasting.Uighur sign language database is the basis for synthesis of Uighur sign language.In this paper we analyse the characteristics of Uighur sign language,use the technology of key frame interpolation to control the gestures of VRML virtual human and have achieved a Uighur gesture editing system by using Visual C＋ ＋ and OpenGl environment.It can display current gestures state of VRML virtual human in real time driven by gestures data.Through this system,the data of gestures have been collected including commonly used Uighur words and 32 Uighur letters.
