Emergency Alert System for Physically Handicapped

Abstract

Emergency alert system consist of development of a wheel chair control. It is useful for physically disabled person with his hand movement. with the help of hand gesture recognition.In earlier systems wheelchair is use for handicap person and this wheelchair had limited range. Due to this we were unable to handle the wheelchair from long distance.The system is classified into gesture unit and wheelchair unit. This wheelchair can be control by simple hand gestures. It consist a Accelerometer sensor which is control the wheelchair hand gesture made by the users and clarify the motion consist by user and moves accordingly. 

People with physical disabilities every time find it complicated to navigate through their house without the assistance of someone. But to navigate through one’s own home without contribute of any one all time can be demoralizing for the person as well. It can be handled wirelessly with hand gesture methods  Gesture control wheelchair is divided into two parts:
1. Transmitter: the Hand gesture
2. Receiver: the wheel chair

The hand gesture reorganization needs both hands Person will be capable to control the chair in limited space, because this project uses the IR sensors which are also helpful in avoiding object. 

With more and more applications of IoT technologies. the quality of life of residents is one of the most important aspects in smart cities. Specially, home healthcare monitoring for the disabled and / or. the elderly has become a focus of recent researches and developments. Existing home healthcare systems have drawbacks. such as simple and few functionalities, weak interaction and poor mobility.This paper presents a home mobile healthcare (mHealth) system for wheelchair users. based on the emerging IoT technologies. The paper focuses on the proposed system architecture and the design of wireless body sensor networks (WBSNs).
