Anagha J. Jadhav, Mandar Padmakar Joshi · 2016
All over the world deaf and dump people face many problems while communication. There are various challenges experienced by speech and hearing impaired people at public places in expressing themselves to normal people. The objective of this paper is to provide the solution to this problem. To reduce the communication gap between the common people and speech impaired people the proposed system is designed and implemented. The embedded system consist of wearable sensing gloves along with flex sensors which are used to sense the motion of the fingers. Indian sign language is used for determining the words. Flex sensors and accelerometer are used as sensor, these sensors are mounted on the gloves, the movement include the angle tilt, rotation and direction changes, these signals are processed by the microcontroller and playback voice is generated indicating signs through speaker.
