This paper provides a method for human identification and obstacle avoidance for visually impaired. Visually impaired people faces lots of difficulty in accomplishing their day to day activities. Among one such difficulty is to recognize the person, this paper comes up with a technique which will helps blind people to identify person approaching them. Here DWT technique is used for face recognition. In this technique the entire image is decomposed into discrete wavelet bands. From this bands required features of image is obtained. This features when subjected to classifier gives proper output by identifying the person. Another part of paper deals with obstacle avoidance by using a blind stick. Blind stick uses an ultrasonic sensor and PIR sensor that detect obstacle at a distance of 100 cm. This stick can be used as alert signal for blind people.

Nowadays, blind or impaired people are facing a lot of problems in their daily life since it is not easy for them to move, which is very dangerous. There are about 37 million visually impaired people across the globe according to the World Health Organization. People with these problems mostly depend on others, for example, a friend, or their trained dog while movıng outside. Thus, we were motivated to develop a smart stick to solve this problem. The smart stick, integrated with an ultrasonic sensor, buzzer and vibrator, can detect obstacles in the path of the blind people. The buzzer and vibration motor are activated when any obstacle is detected to alert the blind person. This work proposes a low-cost ultrasonic smart blind stick for blind people so that they can move from one place to another in an easy, safe and independent manner. The system was designed and programmed using C language. Keywords: Arduino Uno, Arduino IDE, ultrasonic sensor, buzzer, motor.

The study focus on a simple method of detecting the obstacle and route by using an ultrasonic sensor that can detect a hole or stair with maximum range about 2 meter. As we can see Blind people is having their trouble to do their life routines because they can’t see even a single things. With our idea, we want to help this kind of people to live their life freely. This ultrasonic blind stick have a several feature that surely can help this blind people to navigate routes and detect an obstacle that surely can make their life routines easier. The user just need to use the blind the normal blind stick , the different is , blind people can detect a hole or stair more faster and easily. Besides that, guardian or user of the blind waking stick can find their stick by remote if they misplaced them.

Changing ideas on the nature of and relationship between the senses in nineteenth-century Europe constructed blindness as a disability in often complex ways. The loss or absence of sight was disabling in this period, given vision’s celebrated status, and visually impaired people faced particular social and educational challenges as well as cultural stereotyping as poor, pitiable and intellectually impaired. However, the experience of blind people also came to challenge received ideas that the visual was the privileged mode of accessing information about the world, and contributed to an increasingly complex understanding of the tactile sense. In this chapter, we consider how changing theories of the senses helped shape competing narratives of identity for visually impaired people in the nineteenth century, opening up new possibilities for the embodied experience of blind people by impressing their sensory ability, rather than lack thereof. We focus on a theme that held particular social and cultural interest in nineteenth-century accounts of blindness: travel and geography.

Blind people face the problem in daily life. They can't even walk without any aid. Many times they rely on others for help. Several technologies for the assistance of visually impaired people have been developed. Among the various technologies being utilized to assist the blind, Computer Vision-based solutions are emerging as one of the most promising options due to their affordability and accessibility. This paper proposes a system for visually impaired people. The proposed system aims to create a wearable visual aid for visually impaired people in which speech commands are accepted by the user. Its functionality addresses the identification of objects and signboards. This will help the visually impaired person to manage day-to-day activities and navigate through his/her surroundings. Raspberry Pi is used to implement artificial vision using python language on the Open CV platform.

Abstract There are still people with disabilities in society who consider them a burden. However, in fact, every child with special needs such as a blind people has the right to have a decent life like any other community. So, we need an orphanage for the blind people with a blind space approach that aims to provide social services to blind children by helping and guiding them towards reasonable personal development and having work skills, so that they can be independent, live properly and have responsibility, both for himself, his family, and society. This research used a qualitative descriptive method by collecting literature studies from national and international journal articles regarding the blind orphanage, collecting data related to the research location and conducting a comparative study of similar buildings in Central Jakarta. This research resulted in a blind orphanage design with a blind space in Jakarta approach that provides disability facilities for visually impaired people, educational facilities, and activity facilities for visually impaired people. It is hoped that the design of the Blind Orphanage can accommodate the activities of the Blind people in Jakarta.

In this paper, we present a low cost hands-free detection and avoidance system designed to provide mobility assistance for visually impaired people. An ultrasonic sensor is attached to the jacket of the user and detects the obstacles in front. The information obtained is transferred to the user through audio messages and also by a vibration. The range of the detection is user-defined. A text-to-speech module is employed for the voice signal. The proposed obstacle avoidance device is cost effective, easy to use and easily upgraded.

Interdisciplinary Contexts of Special Pedagogy, no. 25, Poznań 2019. Pp. 353-371. Adam MickiewiczUniversity Press. ISSN 2300-391X. DOI: https://doi.org/10.14746/ikps.2019.25.15 People with visual impairment use information from other senses to gain knowledge about the world around them. More and more studies conducted withthe participation of visually impaired people indicate that data obtained through auditory perception is extremely important. In this context, the ability of echolocation used by blind people to move independently is interesting. The aim of the article is to present echolocation as a method supporting spatial orientation of people with visual impairment. The article presents the results of empirical studies of echolocation. It also presents the benefits of using this ability in everyday life and signals research projects related to the methodology of teaching echolocation in Poland.

Abstract The proposed robot aims to serve as a personal assistant for visually impaired people in obstacle avoidance, in identifying the person (known or unknown) with whom they are interacting with and in navigating. The robot has a special feature in truly locating the subject’s location using GPS. The novel feature of this robot is to identify people with whom the subject interacts. Facial detection and identification in real-time has been a challenge and achieved with accurate image processing using viola jones and SURF algorithms. An obstacle avoidance design has been implanted in the system with many sensors to guide in the correct path. Hence, the robot is a fusion of providing the best of the comfort and safety with minimal cost.

Internet of things is where all the things are connected to the internet and communicate with each other. There are many applications of the IoT in various fields such as healthcare, agriculture, industries, and logistics, and even for empowering people with disabilities. There are many previous work for the blind people using IoT in finding the obstacles many navigation applications have been developed. In this chapter, a system is proposed to assist blind people in reading books. This method is based on capturing the text book pages as an image and processing them into text with speech as an output.
