<p>Visually impaired persons possess a specific set of functional and sensory requirements for their successful existence in architectural environments. Unfortunately, a majority of our existing built infrastructure is ill-equipped to address these requirements. Both existing forms of solution for this issues, technological and architectural, are incapable of compensating for the inadequately considered design of public spaces and are subject to widespread general criticisms from the vision loss and architectural community (Human Rights Commission, 2012; Pawluk et al., 2015).   This thesis recruits the native capabilities of emerging consumer-level digital technologies in order to explore new solutions to this complex problem. This research saw the proposition tested through the development of a digital platform which blended the design strategies of universal design and assistive technologies with a wide range of theoretical perspectives drawn from medical, psychological, sociological, and geolocational literature. The resulting integration generated unique forms of architectural engagement which improve the spatial comprehension abilities of the visually impaired.  The early design outcomes focus on two distinct modes of engagement with a virtual, augmented environment. The first is direct bodily interaction, in which the human-scale perception of the user is bolstered through an object-detection system, which provides users with sensory cues to identify objects in their direct vicinity. The second was the development of various methods for distance-based spatial engagements. Engagement with an environment from a distance significantly expands the scale of potential spatial understanding. These methods allow users to explore spaces in a myriad of different ways, with each mechanic providing different environmental information through diverse sensory outputs. The later design work reflects on these creations and through a process of redevelopment and evaluation draws larger observations regarding the development of the tools and what they offer in terms of spatial understanding. Final conclusions from the thesis provide a framework for research which would allow for the digital adaptation of our currently unsuitable infrastructure.</p>

Digital transformation of the modern world requires any person, including people with partial or complete vision loss, to have new competencies in organizing their own lives. The share of high-tech services is growing in almost all areas of library and information activities.The process of inclusion of visually impaired people in the world of new opportunities is directly related to the formation of the image of socially active special library. The author analyzes the management decisions and development of the Novosibirsk Regional Special Library for the Blind and Visually Impaired as a consumer and participant of the intersectoral and interdepartmental market of rehabilitation industry products. The article reveals the role of assistive (auxiliary) technologies in the expansion of a number of educational services for the interested social and professional groups of the population.The empirical basis of the article is the results of the information and applied development of the assistive technology sphere by the specialists of the Novosibirsk Regional Special Library for the Blind and Visually Impaired. Various social, technical, regulatory and economic aspects have defined the development of the institution over a long period of time. The interdisciplinary nature of the proposed method involves the use of advanced assistive technologies as the basis for expanding the services of special library.The article considers the proactive approach that takes into account the priorities of the readership as an actual and effective way to develop a system of special library and information services. The author proposes and approves as innovation the idea of using the achievements of the related field of activity — accessibility technologies. Educational and training activities of the library in this context become a targeted tool for informing and motivating specialists of various branches. The article shows the need for additional efforts to organize and coordinate the work in the conditions of different levels of competence of specialists. Advanced development of assistive technologies allows expanding the range of users.

Introduction Knowing how to gather information from graphics and to use that information to solve mathematics problems is an important skill. Prior research indicates that many students with visual impairments face considerable challenges when attempting to locate information in math graphics. Little is known about how teachers of students with visual impairments support their students in acquiring graphics skills. Methods Eleven teachers of visually impaired students participated in focus groups. Sessions were audio-recorded and transcribed. Themes were identified. Results The teachers described the importance of individualizing instruction for the student, teaching a systematic approach, and ensuring that graphics are clear to them. Discussion From an early age, visually impaired students need explicit instruction in how to access information in graphics. The use of prescribed low vision devices, manipulatives, and systematic instruction are integral to student success, as are the design and production of clear and accurate graphics. Implications for practitioners Teachers of visually impaired students utilize a variety of strategies to support students in accessing information in graphics. A curriculum and guidelines to assist them in supporting a wide range of learners would be valuable to the field of vision loss.

In this paper, we report on the “VIsual Dataset for Visually Impaired Persons” (VIDVIP), a dataset for obstacle detection during sidewalk travel. In recent years, there have been many reports on assistive technologies using deep learning and computer vision technologies; nevertheless, developers cannot implement the corresponding applications without datasets. Although a number of open-source datasets have been released by research institutes and companies, large-scale datasets are not as abundant in the field of disability support, owing to their high development costs. Therefore, we began developing a dataset for outdoor mobility support for the visually impaired in April 2018. As of May 1, 2021, we have annotated 538,747 instances for 32,036 images in 39 classes of labels. We have implemented and tested navigation systems and other applications that utilize our dataset. In this study, we first compare our dataset with other general-purpose datasets, and show that our dataset has properties similar to those of datasets for automated driving. As a result of the discussion on the characteristics of the dataset, it is shown that the nature of the image shooting location, rather than the regional characteristics, tends to affect the annotation ratio. Accordingly, it is possible to examine the type of location based on the nature of the shooting location, and to infer the maintenance statuses of traffic facilities (such as Braille blocks) from the annotation ratio.

In This Paper we present a real time domain obstacle detection system for the visually impaired persons to improve their mobility in daily life with the help of obstacle detection sensor installed in their walking stick .System is having a lower cost so it is easily purchasable so it can have a major significance in life of visually impaired persons. This Paper proposes a system to detect any object attached to the floor regardless to their height [1]. Obstacle on the floor in the front of user can be reliably detected in real time using the proposed system implemented by the IR sensor installed on the walk stick of the visually impaired person. Project also contains a navigation system for visually impaired persons to make the life of such persons easier up to some extent. This project is suited for the area where the possibility of blind person is high (like blind school, college)[6]. For transport facility of blind we have first decided the common bus roots of blind then we have placed RF tag to all those buses with unique code. At the second side we have placed RF reader, microcontroller and voice processor. The RF reader receive unique code, microcontroller process this code with defined code, if match found, voice processor get activated and starts speaking bus name, initial destination and final destination. The obstacle detection is also included in the project with voice. The system aims at increasing the mobility of visually impaired people by offering new sensing abilities.
