The fundamental issue with daze individuals is the way to explore their approach to any place they need to go. This venture is intended to assist the visually impaired with conquering the absence of visual sense, by utilizing different faculties like sound and contact. The framework additionally comprises a ringer to produce a caution sound and to create vibration signals. The framework utilizes sound and vibration signs to advise the client about the forthcoming obstacles. As the distance between glove and snag diminishes, recurrence of both sound and vibration signal increments. Consequently, the framework assists with facilitating the routing cycle for the poor. This framework offers a minimal expense, solid, compact, low force utilization and strong answer for routes with self- evident short reaction time. Keywords: Visually impaired, Vibration signal, Sound, Obstacles etc. 1. INTRODUCTION The third eye for dazzle is a wearable gadget that can assist outwardly debilitated individuals with moving by themselves in an indoor environment. Visually impaired people to move from one spot to another independently. This gadget is useful particularly when the individual needs to move around a house or some indoor spots without anyone else. In this gadget, the distance of the snag is dictated by utilizing an Ultrasonic module and a Microcontroller. The snag distance is estimated and educated to the outwardly impeded individual as a ringer and vibrations. The individual can move in other bearings and stay away from crashes utilizing this. The end consequences of the work would be gloves with a wearable band joined to the gloves to which every one of the segments is associated on a PCB, which works with serious level of precision and unwavering quality. 2. EXISTING SYSTEM Research has been conducted for new devices and technologies to design a good and reliable and efficient system for blind or visually impaired people to detect the obstacles and warn or alert them at dangerous places or obstacles. One sound for free for travel direction and the other for blocked, it was difficult for the person to differentiate the sounds. Another problem was the system would not know the user's momentary position. Time and again there have been innovations in wearable technologies for the blind. Another Visual Impairment Aid makes use of a similar concept. We have tried to build on this existing glove by making it less complex and easily constructible so as to be marketed on a large scale. The glove presented in this also happens to be much cheaper than the Visual Impairment Aid with little to no depreciation in its performance. 3. PROPOSED SYSTEM The proposed system deals with the cheaper and effective obstacle detection with a wide range of coverage. The device includes the following components: • Arduino UNO • Ultrasonic sensor • Bread board • Buzzer • 5 mm LED: Red • Slide Switch • Female Header • Male Header • Jumper wires • Power bank • Some elastics and stickers Let us see about the components in brief: 3.1. ARDUINO UNO: The Arduino is an open-source hardware and software that can make a user to do effective operation in it. The Arduino is a microcontroller. These microcontroller devices help in sensing and controlling the objects in the real-time situations and environment. These boards are available cheaper in the market. There are a number of inventions performed in it and still it is going on. Arduino is an open-source electronics platform based on easy- to use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. The operating voltage is 5V. Input
