使用OpenGL实现了手语AVATAR,以使用户易于在各种操作系统中执行3D图形应用程序。符号动画数据是使用词素分析仪从符号单词数据库中提取的,不仅应用于更新每个身体部位的位置和方向,还可以根据元音的唇部和下巴运动的产生。此外,头像还提出了眉毛,撕裂和脸部肤色的结合描述的面部表达。为了生成平滑的符号运动,我们在连续的键帧之间采用了一种插值方法,并提出了一种搜索算法,该算法快速从符号Word数据库中提取符号动画数据。
A sign language avatar is realized using OpenGL to make users easy to execute a 3D graphic application in various operating systems. Sign animation data is extracted from sign word database using a morpheme analyzer and applied not only to update of the position and the orientation of each body part, but also to generation of lip and jaw motion according to vowel. In addition, the avatar presents facial expression described by the combination of eyebrow shape, tear and face complexion. To generate smooth sign motion, we adopt an interpolation method between consecutive key frames and propose a search algorithm which quickly extracts sign animation data from sign word database.
