KGISL INSTITUTE OF TECHNOLOGY
“We see with our brains than with our eyes”.
The sole principle used to visionise a blind is
–”DECEIVING OUR BRAINS”.
METHODS USED ARE
b)Nano tube implant.
c)Digital artificial vision.
e)Braile type writer
BRAILLE TYPE WRITER:
• Using a signal processor synchronized
signals are converted to pricking pulses,
which is sensed on a bad interfaced on the
stomach or hand of blind.
The BIONIC EYE implant are
of porours polyethylene
,aluminum oxide .
DIGITAL ARTIFICAL VISION
• MICRO COMPUTER
a)Sub-notebook computer-Employs a 233
MHZ processor, 32 MB of RAM,4 GB hard
b)MICRO CONTROLLER-Consists of
pulses 30 HZ to produce each frame
• SOBEL filter is most common approach
• They are Gx and Gy
• A new optical device, called the
microelectromechanical systems– (MEMS-
) based adaptive optics phoropter
(MAOP), will greatly improve this process.
• The electrodes are embedded in silicone-
based substrate polydimethylsiloxane

Electrodes (phosphenes) Visual field
The original image seen by
the camera and phosphene
image seen by the visual
field in the brain of the
blind human are as shown
• Age related retinal diseases like
macular dysfunction, retinitis
pigmentosa can be averted using
• As now, only black and white images
are seen by this AVS system, research is
being carried to visualize coloured images
by using optical fiber technology.
• Research is being carried to
replace the electrode implantation with ray
or wave devices
• NVCS can be nano fabricated on a
• “WISHING A REMARKABLE
PROGRESS IN THE
DEVELOPMENT OF THIS
ARTIFICIAL VISION SYSTEM,
SUCH THAT EACH AND EVERY
BLIND PERSON TODAY, IS NEVER
A BLIND TOMMOROW.”
