“…Many people with disabilities also use technologies such as websites, online forums, online imagery and existing location-based technologies to assess the accessibility of a building and often cross-check using multiple strategies [28,29,35]. 1 These sections are an extended version of [18] Technology is used by people with VI to build a mental map [30] before starting a journey by retracing the steps and recounting details of a trip such as street names or intersections [35].…”

“…Thus, it is essential for orientation and mobility that users get access to more speciic information about indoor environments. The current paper is an expanded version of the paper "Travelling More Independently: A Requirements Analysis for Accessible Journeys to Unknown Buildings for People with Visual Impairments" published at the ASSETS conference 2020 [18]. We extended the conference paper by analyzing the answers of people with MI, as well as the data of people with VI in more depth, and compare these results.…”

It is much more difficult for people with visual or mobility impairments to prepare for a trip or visit unfamiliar places than it is for people without disabilities. In addition to the usual travel arrangements, one needs to know if the various parts of the travel chain are accessible. To the best of our knowledge, there is no previous work that examines in depth travel behaviour for indoor environments for both trip planning and execution, highlighting the special needs of people with low vision, blindness or mobility impairments. In this paper, we present a survey with 125 participants with blindness, low vision and mobility impairments. We investigate how mobile they are, what strategies they use to prepare a journey to an unknown building, how they orient themselves there and what materials they use. For all three groups, our results provide insights into the problem space of the specific information needs when planning and executing a trip. We found that most of our participants have specific mobility problems depending on their disability. Feedback from the participants reveals there is a large information gap, especially for orientation in buildings, regarding availability of high-quality digital, tactile and printable indoor maps, accessibility of buildings and mobility supporting systems. In particular, there is a lack of available and high-quality indoor maps. Our analysis also points out that the specific needs differ for the three groups. Besides the expected between-group differences, also large in-group differences can be found. The current paper is an expanded version of [18] augmented by data of people with mobility impairments.

“…However, the same devices and software applications can represent a different form of barrier: if their user interface is not accessible or not suitable for assistive technologies, they fail in reaching the goal of providing persons with disabilities with a tool that could actually enforce their independent living [117]. Thus, current research on wayfinding and navigation technologies should consider both types of accessibility requirements: accessibility of the urban environments and buildings [51] and accessibility of the applications that provide information about it (e-accessibility) [102].…”

Urban environments, university campuses, and public and private buildings often present architectural barriers that prevent people with disabilities and special needs to move freely and independently. This paper presents a systematic mapping study of the scientific literature proposing devices, and software applications aimed at fostering accessible wayfinding and navigation in indoor and outdoor environments. We selected 111 out of 806 papers published in the period 2009–2020, and we analyzed them according to different dimensions: at first, we surveyed which solutions have been proposed to address the considered problem; then, we analyzed the selected papers according to five dimensions: context of use, target users, hardware/software technologies, type of data sources, and user role in system design and evaluation. Our findings highlight trends and gaps related to these dimensions. The paper finally presents a reflection on challenges and open issues that must be taken into consideration for the design of future accessible places and of related technologies and applications aimed at facilitating wayfinding and navigation.
