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

5. LITERATURE SURVEY Serial No. Title Publisher Highlights 1. Ultrasonic Distance Measuring Device Study (Similar to the concept of third eye gloves) 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.

A prototype of a hand glove is addressed in this work, with the goal of reducing problems to some extent.” 3. Reference paper: Benjamin He developed a laser cane with three photo diodes and three laser diodes function as receiver making an optical triangulation. The laser cane generally detects obstacle in three specified directions. 4. Reference paper: In the year (2020) Anisha M R She developed a first-generation prototype model of the glove has been created. We were able to devise a workable solution. that will benefit everyone after analyzing the difficulties in society.

9. HARDWARE AND SOFTWARE 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, i ncluding 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 S upply: 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.

15. FUTURE IMPROVEMENTS 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 features. Simple, portable and convenient Wearable on a daily basis Low-cost solution for the market Compact yet highly sensitive Improved Navigation and Mobility, Enhanced Safety.

17. RESULT

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 conducted with consideration for for the experiences and requirements of blind individuals. Furthermore, it is vital that any resulting product is affordable, easily accessible, and safe to use.
