This dissertation presents a system that can assist a person with a visual impairment in both navigation and movability. Meanwhile, number of solutions are available in current time. We described some of them in the later part of the paper. But to date, a reliable and cost-effective solution has not been put forward to replace the legacy devices currently used in mobilizing on a daily basis for people with a visual impairment. This report first examines the problem at hand and the motivation behind addressing it. Later, it explores relative current technologies and research in the assistive technologies industry. Finally, it proposes a system design and implementation for the assistance of visually impaired people. The proposed device is equipped with hardware like raspberry pi processor, camera, battery, goggles, earphone, power bank and connector. Objects will be captured with the help of camera. Image processing and detecting would be done with the help of deep learning, R-CNN like modules on the device itself. However, final output would be delivered by the earphone into the visually impaired person’s ear. The research work contains the methodology and the solutions of above mention problem. The research works can be used in practical use cases, for visually impaired person. The system proposed in this project includes the use of a region based convolutional neural network as well as the use of a raspberry pi for processing the image data. System includes tesseract library of programming language python for OCR and give output to the user. The detailed methodology and result are elaborated later in this paper.

This article thematizes relations between visual impairment and urban space, drawing from the analytical perspective of actor-network theory (ANT). It traces the ways in which visually impaired people create specific connections with space and how they transform it. Urban space is configured for use by able-bodied persons, for whom movement within it is easy and seems to be disembodied. However, for those who defy the standardization of space, the materiality of movement is constantly present and visible, because the passages are difficult to make and are not ready in advance. These materialities, as well as the strategies that people use to make connections with urban space, differ according to the assemblages that visually impaired people create. A route is different with a cane, a human companion, a guide dog, or the use of a combination of such assistance; the visually impaired person pays attention to different clues, follows specific lines, and other information is important and available. Each configuration makes it possible or impossible to do something; this shows disability as dynamic, and demonstrates the collective nature of action, which is more visible and palpable in the case of a disabled person.

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.

The Way

Mobility for people with visual impairments is a challenge in placeswhere there is no knowledge of obstacles. Research carried out inthis work identified that people with visual impairment have difficultieswith obstacles located above 1 meter. Thus, an approach isproposed to notify the visually impaired person through sound andvibration about such obstacles. The proposed solution is available onthe ThingSpeak platform and components such as microcontrollers(ESP8266 NodeMcu ESP-12), sensors, buzzer and GPS were usedin its development. Results confirmed that the proposed approachcorrectly identified the existence of obstacles with a height equalto or greater than 1 (one) meter in the way of visually impairedpeople.

Objective: to analyze mental health in the face of visual impairment, identifying the stages of psychological distress in the encounter with the not seeing. Method: This is an exploratory study with a qualitative approach. Fifteen adults with visual impairment attended at a specialized ophthalmology ambulatory in a university hospital in the city of Natal, Rio Grande do Norte, Brazil were studied, from June to August 2015, through a semistructured interview. The speeches were analyzed based on the theory of mourning. Results: the results showed that the mental health of the visually impaired person is structured through a normative apparatus constituted of individual and social attributes dynamically constructed. These attributes are related to the constitution of stages of mourning, characterized by shock, denial, bargaining, depression, and acceptance. The mental health of the visually impaired person contemplates the phases of normal mourning, established before the condition of visual loss, as structuring mode in a process of personal reconstruction, reflected in the ways of walking the life, proper from each one. Conclusion: With this study, it was possible to understand the ways of constitution and reconstitution of people in dealing with a new condition, the one of visual impairment, providing caregivers, family, and society with an ethical spirit and solidarity, more compliant and humane in the to deal with people with disabilities.

Visually Impaired Persons

Visual impairments often pose serious restrictions on a visually impaired person and there is a considerable number of persons, especially among aging population, which depend on assistive technology to sustain their quality of life. Development and testing of assistive technology for visually impaired requires gathering information and conducting studies on both healthy and visually impaired individuals in a controlled environment. We propose test setup for visually impaired persons by creating RFID based assistive environment – Visual Impairment Friendly RFID Room. The test setup can be used to evaluate RFID object localization and its use by visually impaired persons. To certain extent every impairment has individual characteristics as different individuals may better respond to different subsets of visual information. We use virtual reality prototype to both simulate visual impairment and map full visual information to the subset that visually impaired person can perceive. Time-domain color mapping real-time image processing is used to evaluate the virtual reality prototype targeting color vision deficiency.

Access or assessment accommodations and arrangements exist to enable students with disabilities to be included in high stakes examinations, and to comply with Equality legislation and the Convention on the Rights of Persons with Disabilities. This article explores the accessibility of digital versions of Question Papers offered by UK awarding bodies for high stakes externally assessed examinations. It raises concerns that question papers from five out of six providers are not adequately accessible for candidates with visual impairment who use screen reader technologies and so asks broader questions about ways in which, even in high income countries with a strong espoused commitment to equality, disadvantage can be compounded rather than addressed. Access arrangements offered by awarding bodies should reflect candidates’ ‘normal way of working’; this article presents original and unique data from a survey of Qualified Teachers of the Visually Impaired in respect of technologies and strategies used by 325 students with visual impairment and finds that up to 16% of these learners are using screen reader tools in school. These candidates may, therefore, be disadvantaged in examinations because the technology they use to access learning resources cannot be successfully utilised to access assessments. The article concludes with recommendations for regulators and providers of assessments.

The loss of vision restrained the visually impaired people from performing their daily task. This issue has impeded their free-movement and turned them into dependent a person. People in this sector did not face technologies revamping their situations. With the advent of computer vision, artificial intelligence, the situation improved to a great extent. The propounded design is an implementation of a wearable device which is capable of performing a lot of features. It is employed to provide visual instinct by recognizing objects, identifying the face of choices. The device runs a pre-trained model to classify common objects from household items to automobiles items. Optical character recognition and Google translate were executed to read any text from image and convert speech of the user to text respectively. Besides, the user can search for an interesting topic by the command in the form of speech. Additionally, ultrasonic sensors were kept fixed at three positions to sense the obstacle during navigation. The display attached help in communication with deaf person and GPS and GSM module aid in tracing the user. All these features run by voice commands which are passed through the microphone of any earphone. The visual input is received through the camera and the computation task is processed in the raspberry pi board. However, the device seemed to be effective during the test and validation.

Autonomous travel is a notable test for visually impaired people and furthermore the expanding accessibility of cost proficiency, superior and versatile advanced imaging gadgets has made a gigantic open door for enhancing conventional checking for record picture securing. We propose a camera based visual help system utilizing raspberry pi for content perusing, movement of items and the sentiments of outwardly hindered people face various challenges to play out their everyday errand. They are absolutely or halfway subject to somebody for help. Their issues have made them to lose their would like to live in this contending society. They look for help from others to control them entire day. This paper expects to make the outwardly debilitated individual completely autonomous in all perspectives. The proposed framework depends on a virtual eye, which conveys to the outside encompassing through a camera. The camera goes about as a consistent wellspring of data to the framework. The information is gotten through the camera. They got signals from the information gadgets are dissected utilizing picture handling in LABVIEW and it reacts to the outwardly debilitated individual through discourse preparing units. The handled data about environmental factors will be educated through the speaker (yield unit) by which outwardly weakened individuals can move and make their work effectively all alone. Also the outwardly weakened individual can naturally control a portion of the home apparatuses like fan utilizing remote correspondence framework.

This study presents as a problem-question whether the use of the audiobook will provide the visually impaired person with the condition to adhere, take ownership, make individual and collective use ofnew technologies, these human creations whichrepresent the possibility of an increasingly growing mastery of information never imagined and its new ways of use.Within this context, the research has the following objectives: to analyze the importance of the audiobook as a pedagogical tool, as mediator of reading classes for students with visual impairment; to analyze whether digital technologies can be used to support the teaching and learning process.Regarding tothe approach ofthe problem, the research has a qualitative focus. For data collection, interviews and online questionnaires sent by WhatsApp were used. The research population and sample comprised 13 (thirteen) subjects. To carry out the interviews, several technological resources were used: Google Meet; WhatsApp and cell phone (phone call).Due to the pandemic –Covid 19 and the inevitable social isolation, digital technology was the best option for conducting the research. The interviews were transcribed using theTranscriber for Whatsappand Call Recorderapplications. The study reveals that digital technologies can and should be used to support the process of teaching and learning to students with visual impairments.That the audiobook represents another reading alternative, a complement, a support, with its own attractions, benefiting people with or without disabilities.As from the social representations extracted from the research subjects’speeches, it was possible to see that assistive technologies need to gotogether with the Braille system, called as a literacy technology, a method whichallows the visually impaired to read and write without intermediation, in other words, the person has direct contact with the text.
