BRAIN CONTROLLED CAR FOR DISABLED USING ARTIFICIAL INTELLIGENCE SEMINAR REPORT
[attachment=67296]
ABSTRACT
This paper considers the
development of a brain driven car, which would be
of great help to the physically disabled people.
Since these cars will rely only on what the
individual is thinking they will hence not require
any physical movement on the part of the
individual. The car integrates signals from a
variety of sensors like video, weather monitor,
anti-collision etc. it also has an automatic
navigation system in case of emergency. The car
works on the asynchronous mechanism of artificial
intelligence. Itβs a great advance of technology
which will make the disabled, abled. In the 40s
and 50s, a number of researchers explored the
connection between neurology, information theory,
and cybernetics. Some of them built machines that used electronic networks to exhibit rudimentary
intelligence, such as W. Grey Walter's turtles and
the Johns Hopkins Beast. Many of these
researchers gathered for meetings of the
Teleological Society at Princeton and the Ratio
Club in England.

A brain-computer interface (BCI), sometimes
called a direct neural interface or a brain-machine
interface, is a direct communication pathway
between a human or animal brain (or brain cell
culture) and an external device. In one-way BCIs,
computers either accept commands from the brain or
send signals to it (for example, to restore vision) but
not both. Two-way BCIs would allow brains and
external devices to exchange information in both
directions but have yet to be successfully implanted
in animals or humans.In this definition, the word brain means the
brain or nervous system of an organic life
form rather than the mind. Computer means any
processing or computational device, from simple
circuits to silicon
