Voice Assistance for Dumb People Based On Hand Gestures
Voice Assistance for Dumb People Based On Hand Gestures

Abstract:

          It is very difficult for dumb people to convey their message to normal people. Since regular people are not trained on hand sign language, the communication becomes very difficult. In emergency or other times when a dumb person travelling or among new people communication with nearby people or conveying a message becomes very difficult. Here we propose a voice assistance system that helps dumb people in conveying their message to normal people using hand motions and gestures

            Voice Assistance for Dumb People Based On Hand Gestures

When power is ON, the position and orientation of hand is obtained from the data glove that consists of 4 Flex sensors on fingers. Flex sensors can measure the bend of the 4 fingers when making a sign. When the user performs a gesture, signals coming from the sensors are amplified via a dedicated amplification circuit to each signal. The voice output is produced if the language is recognized by the regular people the dumb person coveys the message based on hand gestures.

Microcontroller (Arduino UNO

Microcontroller (Arduino UNO

The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.

 

flex sensor

 

flex sensor

This sensor can detect flexing or bending in one direction. They were popularized by being used in the Nintendo PowerGlove as a gaming interface. These sensors are easy to use, they are basically resistors that change value based on how much their flexed. ... When flexed all the way the resistance rises to ~100KΩ

Arduino IDE

The Arduino Integrated Development Environment (IDE) is a cross-platform application (for Windows, macOS, Linux) that is written in functions from C and C++. It is used to write and upload programs to Arduino compatible boards, but also, with the help of third-party cores, other vendor development boards

.Embedded C

embedded c

Embedded C is a generic term given to a programming language written in C, which is associated with a particular hardware architecture. Embedded C is an extension to the C language with some additional header files. These header files may change from controller to controller
