A two-way communication system with Morse code medium for people with multiple disabilities

This paper proposes an innovative, Morse code based two-way communication system with four user-accessible modes. The four modes are determined to provide speech to Morse vibrations and Morse to speech conversion. The proposed system is embedded with touch, gesture, vibration, microphone, and speaker modules coupled with a microprocessing unit. An S-Morse dictionary convert Morse code pattern read from the touch sensor to voice and speech from microphone to Morse vibration. A gesture recognition model using the SVM algorithm is implemented for the selection of user-accessible modes. The system modes also send and receive text data from an android application through a cloud network. The received and sent data will be converted into vibrations of Morse code pattern and voice forms respectively. The proposed method is strengthened by validating Morse conversion, machine learning algorithm accuracy, gesture recognition accuracy, Morse time analysis for alphabets, word and gesture analysis for mode selection.
