3D Presentation

The presented paper aims to create a more affordable way to present culturally-historical objects like paintings, masterpieces, tapestries, objects, artifacts, etc., and make it more accessible to visually impaired or blind people. The State of the Art of the team shows that the already used method received good feedback at the exhibition "Battle of Pavia 1525" in Pavia, Italy, from more than 11 000 people, who take part in exhibition in Italy. This encouraged the team to continue developing the idea. An approach on the base of the Bulgarian patent application named “Tactile graphical tile for visually impaired people” is described. By using innovative methods for 3D digitalization, also by using more accessible and affordable materials for 3D printing the culturally- historical objects can be presented in schools for visually impaired or blind people. By using approaches are shown how can be reduced the time for 3D digitalization. Conclusion and future developments are presented.

Electronic Travel Aids

This review deals with a comprehensive description of the available electromagnetic travel aids for visually impaired and blind people. This challenging task is considered as an outstanding research area due to the rapid growth in the number of people with visual impairments. For decades, different technologies have been employed for solving the crucial challenge of improving the mobility of visually impaired people, but a suitable solution has not yet been developed. Focusing this contribution on the electromagnetic technology, the state-of-the-art of available solutions is demonstrated. Electronic travel aids based on electromagnetic technology have been identified as an emerging technology due to their high level of achievable performance in terms of accuracy, flexibility, lightness, and cost-effectiveness.

Baseline Solution

Precise and reliable directional feedback is crucial for electronic traveling aids that guide visually impaired people along safe paths. A large proportion of visually impaired people can determine light position using their light perception. This work presents LightGuide, a directional feedback solution that indicates a safe direction of travel via the position of a light within the user's visual field. We prototyped LightGuide using an LED strip attached to the brim of a cap, and conducted three user studies to explore the effectiveness of LightGuide compared to HapticBag, a state-of-the-art baseline solution that indicates directions through on-shoulder vibrations. Results showed that, with LightGuide, participants turned to target directions in place more quickly and smoothly, and navigated along basic and complex paths more efficiently, smoothly, and accurately than HapticBag. Users' subjective feedback implied that LightGuide was easy to learn and intuitive to use. The potential limitations of using LightGuide in real environments are subsequently discussed.

Special Library

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.

Cultural Constructions

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.
