Person suffering from quadriplegia cannot operate the typical wheelchair available for disabled person. As an attempt to make lives of the people suffering from this phenomenon simple, the project aims at using eye pupil movement to control wheelchair. The web camera attached to the laptop placed on the wheelchair of the user will capture the image of the eyes. These eye movements are processed using MATLAB software and serial commands are sent to Arduino circuit which then controls the motor attached to the Wheelchair. Ultrasonic sensor is used to detect obstacle in the path of wheelchair.
To ensure user’s safety, an obstacle detection feature using ultrasonic sensor is included. Their outputs are given as inputs to the NI myRIO microcontroller, which provides the information to the driver circuit allowing the wheelchair to move in the desired direction. Keyword.

INTRODUCTION A considerable fraction of the world’s population is suffering from some form of physical disability.
GUI of the android application have the facility to control the direction of the wheelchair and it has the provision to control electrical home appliances using radio frequency concept. System design uses IOIO board which contains a single MCU that acts as a USB host and interprets commands from an android application. Pin 31 and pin 33 of IOIO board are used as PWM output which is given to DC motor driver MD30C and pin 32 and pin 34 are used as direction control pins. Output of the DC drive is fed to two DC drive to move the wheelchair in different direction. For forward movement of the wheelchair both DC motor are rotated in forward direction.
Abstract— In this paper, we proposed an assessment robotic system for wheelchair control based on touchscreen. This project is a more important issue in this days because of they are competing the normal persons in all the aspects by ignoring their disability. So that they need a personal assistive system which will help them to move from one place to another in their homes and offices. The implemented robotic wheelchair is having a capacitive touchscreen for controlling the movement of the wheelchair. There is also a voice playback module which is prerecorded with the voices like asking water, food and medicines.
ROBO WHEEL Angel Mary, Favas K S, Vishnu Kumar Students, Computer Science Matha College of technology, MG University email@example.com Arun Mathew Asst. Prof, Computer Science Matha College of technology, MG University firstname.lastname@example.org Abstract- This paper introduces an automated system is to be developed to control the motor rotation of wheel chair based on hand movement of physically challenged person. In order to facilitate these people for their independent movement, a tab or a mobile phone is used. Based on the data from android application will generate command signals which will be received by controller fitted on the back of the chair using Bluetooth. There are modes of working as movement control and home automation.
The design must not impede the collapsibility of the wheelchair. The goal of a wheelchair is to increase its user’s mobility. For ease of travel and storage, many manual wheelchairs have been designed to be able to fold or collapse, and implementing this feature is important in increasing portability of the chair. 6. Propulsion must be available for either side of the chair.
It augments the physical world around us and converts them into digital information. It works with the help of natural hand gestures . Steve Mann of MIT media lab developed Sixth Sense Technology in 1994 and later on advancement have been made. Later on Pranav Mistry of MIT media lab made the proper modification and implementation of Sixth Sense Technology in 2009. It comprises of a pocket projector, camera, color bands, mirror and all are connected to the mobile computing devices .
The electric wheelchair has become the most popular type of mobility device for little people that have become immobile. The electric wheelchair allows for more freedom for the individual. The electric wheelchair has an electric motor which allows for movement. The electric wheelchair has become so remarkable in ways that it made life easier for disabled people. Getting around by yourself in a wheelchair that you must push yourself is exhausting and difficult.
Furthermore it has been considered also the need of developing measures that capture the impact of rehabilitation interventions on the patients’ functional ability in real-life conditions, like the home and community settings [162, 172]. An emerging therapeutic approach called Constraint-Induced Movement Therapy (CIMT) has been shown to prevent and/or reverse learned non-use following stroke [1 pr]. CIMT involves constraining the unaffected limb thereby forcing the patient to use their affected limb. In this way the neuroplasticity is stimulated and the motor function is improved, simply forcing the use of the affected limb [2 pr]. CIMT is intended for stroke survivors who retain the ability to flex the wrist and move their arm and fingers.
In traditional days, wheelchair is been operated using joystick,mouse or keyboard which proved to be effective only for healthy people. Providing a robot that would respect all constraints mentioned above is the ultimate goal of BCI. Brain computer Interface is a direct communication pathway between human brain and an external communication devices.BCIs sometimes called as Mind-machine Interface or Brain-Machine Interface. Basically there are two types of Brain Computer Interface techniques, invasive and noninvasive technique. In invasive technique the brain signals are recorded by an implanting electrode directly into cortex of brain.
