Embedded Home Automation for Visually Impaired

Abstract

This paper aims to develop an embedded system which is used to control the home appliances through voice and mobile for the visually impaired people and also for the physically challenged people. Though various techniques have been proposed and are available currently, most of them are not user friendly for the visually impaired people and thus a friendly system has been developed for them. As speech is the preferred mode of operation for these people, this project intends to make use of voice oriented command words for controlling purposes. Further the hand-held unit has a microphone to receive the voice input and is a wireless module which uses the Radio Frequency (RF) technology. This project uses the DTMF technique in the mobile device so as to avoid any scenario involving visual interaction for the benefit of the user. Also in this module there is a voice feedback as an acknowledgement both for the voice controlled automation and automation through mobile.

Wireless Home Automation Control Using Voice Recognition Based on HM2007

“…Else its need to train board again after each power up. The board is feeding from external voltage to power the board as shown in figure (2) [5].…”

“…Press "1" (display will show "01" and the LED will turn off) on the keypad shown in figure (2), then press the TRAIN key ( the LED will turn on) to place circuit in training mode, for word accepted one, then say the target word into the onboard microphone (near LED) clearly. The Web Site: https://jutq.utq.edu.iq/index.php/main Email: journal@jutq.utq.edu.iq circuit signals acceptance of the voice input by blinking the LED off then on.…”

“…Speech is the oldest way for the human being used to communicate after sign language so that the speech recognition tends designer to use it to communicate with the machine, robotics and other application. The system introduced in this paper proposed a speech recognition control using hm2007 and Bluetooth as wireless technology to control the home appliances [2]. The system is used to provide an easy way to manage the house especially for those who have disabilities or Elderly people.…”
