3. ARTIFICIAL EYE
INTRODUCTION
 Prosthesis used to replace a missing or damaged eye.
 We see with our brains than our eyes.
 Principle-Deceiving our brains.
 Read large letter and identify the objects.
 Camera interact with brain by stimulating optic nerve.

6. THE WORKING OF ARTIFICIAL
VISION
26/08/2019 Dept. of EE
6
 Consist of a camera which transmit high frequency radio signal
to microchip.
 Electrodes in chip convert it to electric impulse.
 It stimulate cells in the retina that connect to optic nerve.
 These impulses reaches the vision processing centre in brain.
 Then it is interpreted as an image.

 LIMITATION
•Surgery is required to implant the electrode array.
•Repairing is difficult if any device got damaged.
•Cost is high.
 CONCLUSION
•People suffering from low vision to completely blind
benefits.
•Currently this technology is used in US.

9. T-Pad(TOUCH SCREEN WITH FEELINGS)
INTRODUCTION
 Creating texture sensations through variations in surface
friction
 Uses vibration to create variable friction areas on a touch
screen.
 System tracks finger position and turns the vibration on and
off.

10. ORDINARY TOUCH SCREEN
26/08/2019
Dept. of EE 10
 Can detect the presence and location of a touch.
 Main components
TOUGH SCREEN CONTROLLER SOFTWARE DRIVER
 Tough screen fails to provide the sense of touch.
 They are dead to the finger.
 This is what the T-Pad enables.

11. TACTILE PATTERN DISPLAY
26/08/2019 Dept. of EE
11
 Creating texture sensations through variations in surface friction.
 Create the illusion of texture on an unadorned piece of glass
 The coefficient of friction between glass and finger tip is about 1
 Uses vibration to create variable friction areas on a touch screen.
 It provides a layer of air between finger and screen
 System tracks finger position and turns vibration turn and off.

12. APPLICATIONS
26/08/2019 Dept. of EE
12
 FOR BLINDS
 FLEXIBLE TACTILE DISPLAY
 COMPUTER BASED TRAINING

13. ADVANTAGES AND
DISADVANTAGES
26/08/2019 Dept. of EE
13
 ADVANTAGES
•User friendly
•Cost-effective
•Can be used with projectors and LCD TVs
 DISADVANTAGE
•High power consumption
 Conclusion
•Has a broad range of controllable friction levels.
•Future work can be done to reduce power consumption.

15. AN ATM WITH AN EYE
INTRODUCTION
 Combines Card ,PIN and Electronic facial recognition.
 Forcing ATM to match live image with stored image.
 User be considered fully verified.
 Damage caused by stolen cards and PINs is eliminated.

(AN ATM WITH AN EYE)
26/08/2019 Dept. of EE

1. Insert the CARD.
2. Input his or her pin when requested.
3. When pin matches video camera captures image of eye.
4. Image is converted into digital code.

5.Compared with one already stored for the individual
6.If the system perceives a match, the withdrawal
of cash is allowed.
7. When a match is made with PIN but
not the images, the bank could limit
transactions
8.user be considered fully verified.

 Advantages
•Stable
•Accuracy
•Comfort
 Disadvantages
•Costly
• The person should be present at the spot
 CONCLUSION:
•Sometimes False acceptances and rejections.
• This type of ATM is more reliable in providing security
by using facial recognition software.
