In this paper, we propose a Voice and Gesture Operated home automation system with a central
controller that allows disabled people to manipulate household appliances with their own voice
and gesture commands. The developed system consists of three main parts, such as Kinect
Motion Sensor, Central Controller, and Network Coordinator. The whole system is based on a
Wireless Sensor Network with a gateway to communicate with each device-controlling unit,
which is fixed in each room or device group. Sensor node houses a Nodemcu and an Optoisolator relay module where each Nodemcu works as a webserver and a client simultaneously,
in order to communicate with the central computer that is allocated with a designated IP
address. With this approach, system shows over 80% accuracy with gesture and voice with
external noise level.
