Smart glasses are designed for all kinds of applications and can be employed in industrial applications, medical and healthcare, consumer, logistics, security, and government, etc. In practice, blind people identify objects or find out walk able paths using a white cane. In spite of a variety of such canes (long cane, guide cane, support cane) available, it doesn't recognize what the actual object is. The guiding sticks give an idea about the objects that lie only in a limited area. Having a camera vision with the support of audio messages for the visually impaired ones gives them a better and more precise sense of their surroundings, especially in an outdoor environment. However, because of the high cost of such devices, the dependency of blind people on common people is consistent. This paper provides a new design of Smart glasses, that the user can wear as normal glasses. These devices are optical head-mounted devices that integrate camera and allow hands-free operations. The fundamental objective of smart glasses for people with normal vision is to blend human vision with the virtual world, producing a kind of ubiquitous computing. But, using this design, the camera placed on the device obtains the video equivalent to the point of view which will be processed for assisting the visually impaired user. There is no need for the user to hold the device in his hands or move it in the necessary position and the vision of the user is not occluded. It will provide a field of view up to 120 degrees.

It is arduous for the visually impaired people to identify every object in their immediate surroundings. With recent advancements in technologies, various products are being developed to overcome these constraints. In contrast to these products, this paper delivers a solution which is portable and economically viable for the visually impaired. A device is being developed, equipped with an ESP32 camera and multiple sensors. A real time system is created which performs object detection on the live streamed data, generated by the camera. In accordance with the data from the sensors, the object and its proximity are identified. A graphical user interface acquires this data and cautions the user about the imminent obstacles, thus guiding them through a pertinent path to reach their destination safely.

Assistive technologies are being developed for visually impaired people to live independently and confidently. This project work proposes a camera-based assistive text reading framework to help blind persons to read text labels and product packaging from hand-held objects in their daily lives. The project work is framed into three stages: Image capturing, Text recognition , Speech output. The project work can be able to insist the blind people in their daily life. The entire application will run on Raspberry pi B. The Raspberry pi B is a credit card sized single computer or So C , or System on a Chip, is a method of placing all necessary electronics for running a computer on a single chip. Instead of having an individual chip for the CPU, GPU, USB controller, RAM everything is compressed down into one package. Raspberry pi B needs an Operating system to start up. In the aim of cost reduction, the Raspberry pi B omits any on-board non-volatile memory used to store the boot loaders, Linux Kernels and file systems as seen in more traditional embedded systems. Rather, a SD/MMC card slot is provided for this purpose. After boot load, as per the application program Raspberry pi B will get execute. Obstacle detection is also provided in this system to recognise the obstacle in front and produce the voice output through Ear phone to blind users.

We have designed a smart glass for the visually impaired people which can recognize objects and measures distance between a blind person and the object by using stereo vision, object segmentation, object recognition by features extracion and learning algorithm (Support vector machine).

Throughout the world, there are 39 million blind people. They face issues in their day-to-day life, be it accessing any written script or even recognising their knowns. The proposed system helps them to recognise people (using face recognition), detect any obstacle in the path (thus providing an ease in their day-to-day life), and convert textual scripts into audio signals (text detection) that are provided to the blind person with the help of a microphone. A RPi camera is used to collect all the visuals and RASPBERRY PI 4Bboard. The conventionally used braille system of reading is not very efficient and also all textual scripts are not available in braille language. Therefore, this device can be a great assistance to a blind person as it is low weight, economical and efficient.

The present innovation has wearable device answers for ease the issues of handicapped people. Student-GLASS is a wearable smart camera device built with a powerful microcontroller that has the ability to see what we, normal people, are seeing, understands the user voice requests and supplies the relevant information using auditory feedback through an earphone. The device aims to improve the quality of life for the blind and visually impaired people and makes them understand their surroundings in a clear way as close as to a normal person at an affordable cost. The device consists of an OV7670 camera sensor based vision module, which can capture up to VGA resolution pictures. The device depends on the services of a smart phone for its voice recognition capabilities. A special voice recognition app must be installed on the smart phone which will communicate with the device using a Bluetooth connection. The device supports memory card up to 4GB, to store the necessary audio and image files. It is capable of generating high quality MP3 audio using VS1011e, a DSP based audio codec chip. The user can interact with the device using a four input capacitive touch buttons built into it. This is helpful when the user doesn't have a smart phone or if its data connectivity is lost.

Wearable technology is the smart devices that can be worn on the body as accessories. Wearable devices such as activity trackers are a good example of the Internet of Things. This technology is basically used for tracking daily activities with the help of some electronic device. Mainly this technology contains smart watches or activity tracker. This kind of technology can be used for many purpose like navigation, health tacker and many other purpose. Wearable technology with image processing will lead to a great futuristic way to solve real life problems and help in solving it way faster than it usually takes and saving the money too. Image processing is a set of computer algorithms which performs processing techniques such as gray scaling or compressing. Image processing can also be helpful in reducing the noise and distortion of an image. In this project, we are going to make a smart wearable glass for visually impaired people which will help them in reading the sign boards and newspaper headline which they feel hard in reading.

Independent living is one of the major concerns for people around the globe. But when it comes to people who are visually challenged, they always rely on other people to get their daily things done. In today's advanced technical environment, the need for self-sufficiency is recognized in the situation of visually impaired people who are socially restricted. More than 90% of individuals with blindness and low vision are mostly seen in developing countries. Visually impaired people always need the help of others, and they rely on others for essential needs. In this project, we developed a system that uses a conglomeration of technologies like Object detection, Speech Recognition, etc, to solve the problems faced by blind people to a certain extent. It makes use of a camera module that acts as a virtual eye for the visually impaired and helps them recognize objects surrounding them. This system also includes other features like searching Wikipedia and sending emails. All the features are implemented using a headset that provides voice assistance for an easier lifestyle for the visually impaired. The whole system was developed in the Python programming language.
