HAND GESTURE BASED WHEEL CHAIR WITH OBSTACLE DETECTION,WIRELESS & GPS TECHNOLOGY USING BLUETOOTH

Abstract

This paper is to develop a wheelchair control which is useful to the physically disabled person with his hand movement or his hand gesture recognition using Acceleration technology. Various Projects have been undertaken previously to develop automatic wheelchair using various technology like button control, Retina controlled. But none have such combined features like Navigation, Dark Room Sensor, Automatic messaging, Obstacle detector. This project will make the user life more comfortable and more independent and is also cost effective and requires low maintenance. Tremendous leaps have been made in the field of wheelchair technology. However, even these significant advances haven’t been able to help quadriplegics navigate wheelchair unassisted. 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. Microcontroller controls the wheelchair directions like LEFT, RIGHT, FRONT, and BACK. The aim of this paper is to implement wheelchair direction control with hand gesture reorganization. The features included in this project are, We are using touch plate sensors to control wheelchair movement, Obstacle detection with the message on mobile via Bluetooth and deviation from the obstacle, Panic Switch with the alert message to the near ones, Illumination of the LEDs in the dark places, Navigation through Google maps.
