Diseño e implementación de un dispositivo electrónico mediante sistemas embebidos para la traducción del lenguaje de señas a palabras.

Abstract

It was developed the design and implementation of an electronic device through embedded systems with the purpose of using it to translate language signs into words. Through the implementation of this electronic device, people with audible disability can communicate in an appropriate way with the rest of people. There were used flexo resistive sensors that measure the deformation caused by flexing the fingers of the hand when making a sing. The reading of the sensors were carried out an ATmega microcontroller which through its analog inputs receives signals from the device and by the output ports send these signals converted into voltages thus through Bascom program this information becomes in words or sounds. With the help of Raspberry Pi embedded system, it is possible to manage the necessary communication protocols (wifi) that has to have both hands the left and right one and also the visualization stage. This process gives as result the translation of 28 words from the alphabet into an unlimited number of words after interchanging them. There were analyzed different electronic devices to conclude that it is relevant to design and manufacture our own data acquisition board. It was because there are several models in the market but none of them was satisfactory to this work needs. Finally it is advisable to use more length sensors for the reason that the range of deformation is broad and therefore the signal sample is optimal to improve the interpretation of the sign.
