Implementation of 3D gesture control system for environmental control

Abstract

The paper presents an explicit and complete implementation of a platform which includes an embedded system and the software necessary to recognize hand gestures on the basis of which an environment is controlled. The platform is developed using an ATmega328P controller and it is based on active infrared (IR) proximity sensor. The proposed platform will be used to detect hand gesture and also approximate the distance with a higher accuracy. This deployment provides the beginner developer with a platform for understanding, testing and learning the concepts of an embedded system, human machine interface (HMI) and a closed loop controller that works in real time. The experimental results were obtained using four active infrared (IR) proximity sensor, a temperature sensor, a buzzer and a relay, all connected to the Atmega328P microcontroller. They are used to demonstrate the functionality of the platform. The main purpose is realization of a reliable gesture sensor which is easy to build and understand, also facilitating future improvements and capabilities.
