Abstract
Este trabajo presenta una alternativa en la construcción de señas de la lengua de señas chilena mediante sub-gestos (no necesariamente tienen significado por sí solos) que pueden ser compuestos para formar diferentes gestos, aprovechando la estructura de esta lengua. Además, este trabajo presenta la implementación de un programa que permite realizar la conversión de glosas en lengua de señas chilena a animaciones 3D.
Adicionalmente, se realiza una revisión de los métodos de ”traducción” de lenguas de señas al idioma hablado, desde intérpretes, reconocimiento de imágenes, video, etc. A nivel país también se han presentado proyectos que tienen estas ideas en su concepción. Sin embargo, no se había profundizado en la forma en la que se construyen las animaciones; este es el objetivo de este trabajo.
Al ser la lengua de señas una lengua natural, posee también características propias de las lenguas orales que podemos aprovechar cuando hablamos de construir una oración o palabra. Debemos entender que algunos términos serán más bien abstractos que literales, como, por ejemplo, al hablar de "palabra” sería más correcto el uso de “glosa”. Siendo la “glosa”, el método que utilizaremos para establecer las relaciones entre el español chileno y la lengua de señas chilena. Esto, sumado a la disponibilidad de recursos tecnológicos que permiten la animación 3D y que se encuentran a libre disposición como Blender y Unity, programas utilizados para crear las animaciones que representan a cada sub-gesto.
This work presents an alternative in the construction of Chilean Sign Language signs by the usage of sub-gestures (which do not necessarily have meaning by themselves) that can be composed to form different gestures, taking advantage of the structure of this language. In addition, this work presents the implementation of a program that allows the conversion of Chilean sign language glosses into 3D animations. Additionally, a review of the “translation”methods from sign languages to the spoken language is made, which includes: interpreters, image recognition, video, etc. At a national level, projects have also been presented that have these ideas in their conception. However, the way in which the animations are constructed has not been studied in depth; this is the objective of this work. Since sign language is a natural language, it also has characteristics of oral languages that we can take advantage of when we talk about ¸constructing.a sentence or word. We must understand that some terms will be abstract rather than literal, for example, when speaking of “word”, it would be more correct to use “gloss”. The “gloss”method will be used to establish the relationship between Chilean Spanish and Chilean Sign Language. This, added to the avai lability of technological resources that allow 3D animation and that are freely available such as Blender and Unity, programs used to create the animations that represent each sub-gesture.
