1. ABSTRACT
• The concept of a “Third eye for Blind" typically refers to a wearable device that
helps individuals who are visually impaired to navigate their surroundings more
easily. One such device is an ultrasonic vibrator glove.
• These waves bounce off objects and return to the glove, where they are
processed and analyzed.
• Based on the distance and location of the objects, the glove then provides
feedback to the wearer through vibrations.

2. INTRODUCTION
• Blindness can significantly impact a person's ability to navigate and interact with
the world around them.
• The third eye for the blind consists of a glove with ultrasonic vibrators attached to
the fingertips.
• The vibrators are controlled by a microcontroller, which receives input from an
ultrasonic sensor mounted on the back of the glove.
• The sensor emits ultrasonic waves that bounce off objects in the surrounding
environment and are detected by the sensor.

3. INTRODUCTION(contd.)
• The microcontroller then converts this information into vibrations that are
transmitted to the fingertips of the glove.
• The sensor then sends this information to the microcontroller, which converts it
into vibrations.
• These vibrations are transmitted to the fingertips of the glove, providing the
wearer with a sense of the objects in their surroundings

4. OBJECTIVES
1. Availability: To make this device simple as well as easily available and be mass produced.
2. Efficiency: To make this device achieve max. possible efficiency.
3. Navigation Simplicity: To help user navigate in his surroundings more easily.
4. Economical : To make the device cost effective so that larger section of blind population can
afford it .
5. Support communication and navigation for visually impaired individuals

John Glendale Eden and
Kyle Pancho
An early passive system, consisting of towed lines of
microphones, was used to detect submarines by 1916,
and by 1918 an operational active system had been
built by British and U.S. scientists.
A major step in the development of sonar systems was
the invention of the acoustic transducer and the design
of efficient acoustic projectors. These utilize
piezoelectric crystals, magneto strictive materials, or
electro strictive crystals.

DESCRIPTION
• HARDWARE REQUIREMENTS:
A. Arduino Nano
Arduino Nano is a popular microcontroller board based on the ATmega328P
microcontroller. It has 14digital input/output pins, 6 analogy inputs, a 16 MHz quartz
crystal oscillator, a USB connection, a power jack, and an ICSP header.
The Arduino Nano can be programmed in C or C++, and there are many libraries
and examples available online to help with programming.

10. HARDWARE AND SOFTWARE
DESCRIPTION(contd..)
B. Ultrasonic Sensor
An ultrasonic sensor is a device that uses soundwaves to detect the distance
between an object and the sensor. It typically consists of a transceiver, which
generates and receives the sound waves, and a control circuit that processes the
signal and determines the distance.
The pin configuration of an ultrasonic sensor can vary depending on the specific
model and manufacturer.

11. HARDWARE AND SOFTWARE
DESCRIPTION(contd..)
C. Buzzer
A buzzer is an electronic device that produces sound when an electrical signal is
applied to it. It is commonly used in various applications, including alarms, musical
instruments, and game consoles.
The buzzer consists of a piezoelectric transducer that converts electrical energy
into mechanical vibrations that produce sound waves.

12. HARDWARE AND SOFTWARE
DESCRIPTION(contd..)
D. Vibration Motor
• Vibrator Motors are the mechanical devices used to develop vibrations.
• A Coin or flat-sized motor works with the help of ring magnet, power supplied brushes connected
to ring magnet, weight and a rotor with the commutation points connected at the front side and the
coils connected on the backside.

13. HARDWARE AND SOFTWARE
DESCRIPTION(contd..)
E. Light Emitting Diode(LED)
• It is a semiconductor device that emit light when current flows through it.
F. External Power Supply:
• NodeMCU ESP8266 operates at 5V & 3.3V.
• It has an on board LDO voltage regulator to keep the voltage steady at 3.3V.

14. HARDWARE AND SOFTWARE
DESCRIPTION(contd..)
• SOFTWARE REQUIREMENTS:
Arduino:
Arduino Software (IDE) contains a text editor for writing code, a message area, a text console, a
toolbar with buttons for common functions and a series of menus. It connects to the Arduino
hardware to upload programs and communicate with them.

• The entire project can be made in the form of jacket, so that the device
doesn't need to be wear one by one.
• Use of specially designed boards instead of Arduino and high quality
ultrasonic sensors makes faster response which make the device capable
of working in crowded.
• Partnerships with organizations and governments can fund and
distribute the device to those who need it most.

16. EXPECTED OUTCOME
The proposed Ultrasonic Vibrator Gloves is expected to have the following remarkable

18. CONCLUSION
• The concept of using an ultrasonic vibrator glove to assist the blind is a promising
development in assistive technology.
• The glove would use ultrasonic sensors to detect objects and obstacles in the user’s path,
and the vibrating motors would provide feedback on location and proximity.
• This could potentially improve the independence and safety of blind individuals, enabling
them to navigate their surroundings with greater confidence.
• Although there are still challenges to be overcome in the development and
implementation of such a device, initial testing and research have demonstrated
encouraging outcomes.

19. CONCLUSION(contd.)
• It is imperative that any research or development associated with this technology is
