Abstract

A hand gesture to speech and text conversion system in 3D that was designed to enhance communication with people with speech impairment. The system has been using a gesture glove, which is a wearable device, and it is connected to an IMU sensor (MPU6050) to record the actual hand orientation, motion, and finger gesture in real time. A sensor data is processed by an Arduino UNO which recognizes the predetermined gestures based on a threshold-based classification. The identified gestures appear on an LCD of size 16x 2 in form of text that is sent wirelessly via a Bluetooth (HC-05) module to a mobile phone to be read out. Buzzer will act as instant feedback when there is a successful gesture recognition and a battery supply is used to create portability. Serious outcomes of the experiments show that the system is an effective low-cost, user-friendly assistive communication aid to speech- and hearing-impaired users because its gesture recognition is performed in real-time with a low latency.
