Hand Gesture Based Home Automation Using Leap Motion

In  this  world  of  abundant  intelligent  devices,  with  an  aim  to  help  the  disabled,  elderly  and  children communicate  with  the  devices  directly  through  gestures  instead  of  the  conventional  switchboards  we propose a system to make human hand tracking and controlling the household appliances possible in real time with minimal latency. The automated system developed until now was limited in the gestures made, not  much  supportive  of  the  gestures  made  by  the  individual  fingers  and  also  slow  in  recognizing  and computing  the  input  parameters.

            For this purpose, we are using a camera to detect the motion of a human hand to control the electronic devices. With the help of these detected motion, MATLAB will generate control signals for a particular gesture or a hand movement and sends the signals via ZIGBEE. The information that received is been collected and processed by ARDUINO controls the other devices. For example, the user showed an index finger to the camera one signal is generated and sends through ZIGBEE, in the received section the ARDUINO compares the received data with the defined data (signals for various gestures). Based on it the ARDUINO actuates the output whether to ON the fan or the light.
