4. The purpose of our project is to use
Raspberry pi, Wheelchair controlling
sense by Eyes technology to design a
system. A common application of this
system is to give access a paralyze
human to access to their wheelchair
without any help of others.
5. Eye controlled wheelchair system is introduced using
camera for capturing the image. Camera captured the
image in real time based on face, eye and eye pupil
detection with minimum delay of time and analyses the
image as input to interface the motor driver IC, to
perform the different operation such as left, right,
forward, and backward and stop.
6. HARDWARE LIST AND SPECFICATIONS OF
MATERIALS USED:
• The list of materials used for the making of this project and its
specification are given below in detail:-
• Arduino mega microcontroller board.
• RASBPERRI PI
• PI CAMERA
• LCD SCREEN.
• RELAY BRIDGES.
• DC MOTORS
• CAR CAMERA
7. ARDUINO CHIP:
• Arduino Uno is a microcontroller
board based on theATmega328P
(datasheet). It has 14 digital
input/output pins (of which 6 can
be used as PWM outputs), 6 analog
inputs, a 16 MHz quartz crystal, a
USB connection, a power jack, an
ICSP header and a reset button.
8. RASPBERRY PI DEVICE:
The Raspberry Pi is a very cheap
computer that runs Linux, but it
also provides a set of GPIO (general
purpose input/output) pins,
allowing you to control electronic
components for physical computing
and explore the Internet of Things
9. HOW CAN RASPBERRY PI DEVICE WORK ON
WHEELCHAIR:
• According to the desired character opted by the
user, the Raspberry Pi gives the signal to the Motor
driver as per the algorithm used in the software
program. Motor driver gets signal using serial
communication and moves the wheelchair either
forward, backward or stop.
11. PI CAMERA:
• This is a pi camera which
is used to take picture of
an eye movements and
note the direction to give
input as which direction
needs to be perform
right now.
12. DC MOTORS:
• DC motors is any of a class of rotary electrical
machines that converts direct current electrical
energy into mechanical energy. The most common
types rely on the forces produced by magnetic
fields. Nearly all types of DC motors have some
internal mechanism, either electromechanical or
electronic; to periodically change the direction of
current flow in part of the motor
13. • We are using two dc motors to
move our wheelchair by giving
direction from the software.
• We are using four Relay bridges to
control the directions of our
wheelchair which will help to
move forward backward left and
right position.
14. FEATURES:
Eye Detection.
People who are unable to walk can use this wheelchair with
eyesight being their guide, the disabled would save energy
and could use their hands and arms for other activities.
Our project is an eye movement controlled wheelchair. A
mounted camera will track eye movement and control a
wheelchair to go forward, left or right, stop. Blinks will
control the wheelchair to stop.
15. CAR BACK CAMERA SCREEN:
• This is a simple mini screen which
shows backward positions either
there is something behind the
wheelchair or its free space to
move backward which is
connected to the arduino chip and
make visible to us .
•
16. Methodology and Algorithms:
The principle of this system is eye pupil
detection and eye tracking based on
image processing techniques. An
algorithm is introduced for detecting the
eye pupil location by Image processing. In
this technique several stages performed
to find out the movement of eye, such as
Eye detection, color conversion, Edge
detection and eye tracking
17. LANGUAGE:
• Python is an interpreter, object oriented,
high level programming language with
dynamics semantics. Its high level built in
data structures, combined with dynamic
typing and dynamic binding; make it very
attractive for rapid application development.
Python’s easy to learn syntax emphasizes
readability and therefore reduce the cost of
program maintenance
