Accessibility is an important element in the life of those who have certain limitations, such as the physically disabled and visually impaired people. However, one of the greatest challenges for this group is to find paths and areas adapted to their limitations while performing their daily activities, since not all environments they explore have these characteristics. Volunteered Geographic Information (VGI) and the crowdsourcing technique appear to be quite useful to develop solutions to overcome these challenges, since these techniques are naturally cheap as they rely on human sensors as the main agent of information delivery. In this chapter, we discuss how these techniques can help mitigate accessibility problems and present some existing research and applications in the field.

Many studies have been conducted on walking support for visually impaired people. However, only a few studies have contributed to the wide understanding of their surrounding environment. In this study, the focus was on the flow of people in environmental information. The flow of people is formed by the presence of many pedestrians in the surroundings of the walking environment. If visually impaired people can independently make decisions by grasping the dynamic environment of people flow, they can walk with ease and peace of mind. A method is proposed that extracts people flow information and selects the information necessary for understanding the environment. The method utilizes vibrotactile stimulation. The effectiveness of the proposed method in determining the surrounding environment and the influence of vibration information on behavior decisions were verified.

The special library acts as the cultural and educational center for visually impaired people, and as the center for continuing education. The multifunctional performance of the library is substantiated. The joint projects accomplished in cooperation with theatres and museums and aimed at integrating the visually impaired people into the society are described. Advanced training projects for the library professionals accomplished in 2018 are discussed.

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.
