ABSTRACT Here is implemented a home navigation system, which comprises of a wheelchair which works on the inputs such as gesture commands via an android phone through Bluetooth and navigates according to command. It can be used by an elderly or physically challenged person to move inside the home without any difficulty. It is also equipped with obstacle avoidance technique, where the person may not be able to provide proper command at the right time. This project is to develop a wheel chair control which is useful to the physically disabled person with his hand gesture recognition using Acceleration technology. It is wheelchair which can be controlled by simple hand gestures. It employs a sensor which controls the wheelchair hand gestures made by the user and interprets the motion intended by user and moves accordingly. In Acceleration we have Acceleration sensor. When we change the direction, the sensor registers values are changed and that values are given to microcontroller. Depending on the direction of the Acceleration, microcontroller controls the wheel chair directions like LEFT, RIGHT, FRONT, and BACK. Keywords- microcontroller, accelerometer sensor, hand gesture, bluetooth. I. Introduction The most common image of disability is the people in wheelchairs. Wheelchairs are used by people who find themselves unequipped to move without external aid. The special needs of the elderly may differ from that of a physically challenged person or a large individual but they all have “special needs” and often require some assistance to perform their daily routine. The physically challenged people, who use a normal wheelchair for navigation, usually require an external person to move around. In this busy world, the elderly people may be left alone at home and also may not find an apt person for external help. Here comes the need of an automated home navigation system, which consists of a wheelchair which can be used by the elderly and the physically challenged people without the help of an external person. The proposed paper can be operated using the gestures of the provided android mobile phone. Patients involved in physical injuries and disabilities with good mental strength struggle to get through places using the conventional hand powered wheelchair. This paper enables an economic assembly in any existing wheelchair that enables a smart system for automated motion which can be controlled by any Smartphone. The main concept involved is „Smartphone‟ which has an operating system as Android which have inbuilt 3 axis accelerometer and Bluetooth Wireless technology . The purpose of our paper can be extended to other mobile devices which has Android powered mobile phone by sharing the application that we have developed. The main second part of our system architecture has a microcontroller SST89E51RD which drives the various directions of the dc motor for directional movement of wheelchair and powers the DC motor for linear motion of the wheelchair. The DC motor controls the front wheels for turning the wheelchair while the pair of DC motor connected to the rear wheels enable linear motion. The aim of this paper is to use wheelchair automatically for moving forward, backward, Left & Right. The overall wheelchair operation uses DC motor and motor driver module combines with microcontroller system . The physically challenged, find
