3rd Hand: A device to support elderly and disabled person

This paper represents a system “3rd HAND”, that can serve a disable person or elder person to perform some of their regular tasks without any helping hand. This system helps a person to switch the regular home loads (light, fan etc.) using his voice commands and his location can be tracked when he travels outside alone with the system. In self-regulated system we used an EASY_VR voice recognition module. The recognized control commands are sent to an ARDUINO for proper program controlling and then to a Bluetooth module. After that, the commands are routed to the target device over Bluetooth network and finally carried out by the control circuit. In GPS tracking system, we used the GPS and SMS services of an android mobile phone. When a client sends a request SMS to the system to get its location, the GPS receiver of the phone calculates the location coordinates and converts it to location name using GEOCODING API. Finally the location name is sent to the client automatically. Generally it is not comfortable and secured for a disabled or elder person to switch their home loads and to travel alone. So the system “3rd hand” provides them a safety switching system and supports them to travel independently in safe.
