Abstract

Deaf communicate naturally through gestural and visual languages called sign languages. These languages are natural, composed by lexical items called signs and have their own vocabulary and grammar. In this paper, we propose the definition of a formal, expressive and consistent language to describe signs in Brazilian Sign Language (LIBRAS). This language allows the definition of all parameters of a sign and consequently the generation of an animation for this sign. In addition, the proposed language is flexible in the sense that new parameters (or phonemes) can be defined “on the fly”. In order to provide a case study for the proposed language, a system for collaborative construction of a LIBRAS vocabulary based on 3D humanoids avatars was also developed. Some tests with Brazilian deaf users were also performed to evaluate the proposal.

FleXLIBRAS:描述和巴西手语的标志动画
聋人自然地通过称为手语的手势和视觉语言进行交流。这些语言是自然的,由称为符号的词汇组成,有自己的词汇和语法。在本文中,我们提出了巴西手语(LIBRAS)中描述符号的形式化、表达性和一致性语言的定义。这种语言允许定义一个标志的所有参数,从而为这个标志生成动画。此外,所建议的语言在可以“动态”定义新参数(或音素)的意义上是灵活的。为了为提出的语言提供一个案例研究,还开发了一个基于三维人形化身的LIBRAS词汇协同构建系统。还对巴西聋哑人进行了一些测试,以评估该提案。
