Resumen


Resumen

En el presente trabajo se diseñó y construyó un guante traductor de lenguaje de señas a mensajes de ayuda elementales. Este sistema tiene como finalidad utilizar un sistema embebido portátil capaz de mostrar al menos 10 mensajes en un LCD para pedir ayuda en tres diferentes idiomas mediante el uso del alfabeto de lenguaje de señas. Este desarrollo tecnológico se divide en 3 etapas: La adquisición de señales eléctricas, el procesamiento de señales y el despliegue de mensajes. Para la adquisición de señales se utilizaron cinco sensores de flexión colocados en cada uno de los dedos. Para el procesamiento de señales se empleó el microcontrolador PIC18f4550, el cual permite convertir la señal analógica proveniente de los sensores de flexión y almacenar las diferentes frases a utilizar. El despliegue de mensajes se realizó mediante un LCD de 2x16 líneas. Además, estos mensajes pueden ser mostrados en 3 distintos idiomas: español, inglés y alemán, así como también se tiene la posibilidad de reprogramar el sistema para diferentes escenarios, de acuerdo con las necesidades del usuario. Los resultados muestran que es posible desarrollar un guante traductor de lenguaje de señas a mensajes de ayuda a bajo costo y eficiente.

Abstract

In this work, the design and construction of a glove translator from sign language to messages for help was carried out. This system is intended to use a portable embedded system capable of displaying at least 10 messages on an LCD to ask for help in three different languages. This technological development is divided into 3 stages: acquisition signals, data processing and print to LCD. For the acquisition of signals, five flexion sensors placed on each of the fingers were used. For the signal processing, the PIC18f4550 microcontroller was used, which allows converting the analog signal from the flex sensors and storing the different phrases to be used. Finally, for the display of messages has been made using an LCD 2x16 lines. In addition, these messages can be displayed in 3 languages: Spanish, English and German; also, these messages can be programed for different cases. The results show that it is possible the construction of a glove translator form sing language to messages for help at low cost and efficient.  

Keywords: Glove, Sign Language, PIC18f4550.
