MICROCONTROLLER BASED SIGN LANGUAGE TRANSLATOR

The communities of vocal impaired and deaf people who use sign language face great
communication difficulties with people who use vocal languages. This project, aims
to contribute towards bringing the gap closer by offering a tool which translates sign
languages to written messages on an LCD display. This report discusses the different
development and implementation issues including gesture modeling, sensor
interfacing, sign recognition and translation. American Sign Language is widely used
in different part of the world including Malaysia; therefore it is considered in this
project. The proposed method utilizes five potentiometers to emulate sensor output, a
microcontroller to acquire, convert, recognize, translate and display the hand gesture
on the LCD unit. The translator can recognize all 26 letters, 10 numbers, and some
phrases and words. The presented work is believed to be an entry to more promising
and rewarding sign language translation-applications in the future.
