“…Cursor-based interactions assist blind people to attend to and interact with physical objects in complex visual scenes [24]. Audio-based AR systems such as Microsoft's Soundscape [39], Blindsquare [7], and NavCog [1,55] act as navigation aids which provide information on points of interest and non-visual landmarks. These systems do not introduce visual augmentations but rather augment the environment with audio cues that help users perform tasks of interest in the real world.…”

Augmented Reality (AR) technology creates new immersive experiences in entertainment, games, education, retail, and social media. AR content is often primarily visual and it is challenging to enable access to it non-visually due to the mix of virtual and real-world content. In this paper, we identify common constituent tasks in AR by analyzing existing mobile AR applications for iOS, and characterize the design space of tasks that require accessible alternatives. For each of the major task categories, we create prototype accessible alternatives that we evaluate in a study with 10 blind participants to explore their perceptions of accessible AR. Our study demonstrates that these prototypes make AR possible to use for blind users and reveals a number of insights to move forward. We believe our work sets forth not only exemplars for developers to create accessible AR applications, but also a roadmap for future research to make AR comprehensively accessible.

“…On example is the NAVIG project, in which an ETA provided the user not only with guidance instructions but also additional cues about the environment [37]. In the NavCog project, a smartphone-based system has been developed which provides turn-by-turn navigation assistance based on accurate real-time localization over large spaces [1].…”

Orientation and Mobility (O&M) classes teach people with visual impairments how to navigate the world, for instance how to cross a road. Yet, this training can be difficult and dangerous due to conditions such as traffic and weather. Virtual Reality (VR) can overcome these challenges by providing interactive controlled environments. However, most existing VR tools rely on visual feedback, which limits their use with students with visual impairment. In a collaborative design approach with O&M instructors, we designed an affordable and accessible VR system for O&M classes, called X-Road. Using a smartphone and a bespoke headmount, X-Road provides both visual and audio feedback and allows users to move in space, as in the real world. In a study with 13 students with visual impairments, X-Road proved to be an effective alternative to teaching and learning classical O&M tasks, and both students and instructors were enthusiastic about this technology. We conclude with design recommendations for inclusive VR systems. CCS Concepts: • Human-centered computing → Virtual reality; Accessibility systems and tools; Participatory design;

“…Related paradigms like contextaware computing [18] expand the vision of how sensing infrastructures can support myriad implicit and explicit interactions; context-awareness has shown promise for supporting accessibility applications such as predictive text suggestions for AAC systems [36,37]. The Internet of Things [3,50] expands on this vision by adding cloud computing capabilities and connectivity to facilitate the creation of "smart" objects, buildings, and even cities [38]; smart buildings and cities have the potential to facilitate accessibility such as if beacons are embedded to support non-visual navigation (e.g., [1,25,26]) or better understandings of the accessibility of urban infrastructure for city planners or pedestrians (e.g., [30,47]). New technologies such as 3D printing and other fabrication options enable embedding of sensors in a variety of materials and objects [63], which could have implications for accessibility (e.g., smart prosthetics [33]).…”

“…Participants ranged in age from 18 to more than 75. We did not collect exact age for privacy reasons, but rather participants reported age in buckets: 18 -24 (5%), 25 -34 (20%), 35 -44 (32.5%), 45 1 https://accessibilityuserresearchcollective.org/ 2 https://www.shepherd.org/resources-healthcare-professionals/research 3 While we would have preferred to use a more screen-reader-compliant survey tool, we have encountered anecdotal reports of screen reader problems with several major survey software providers (whose products claim full accessibility compliance), and have been unable to fnd full-featured survey software that is fully accessible. Indeed, the challenges of survey software providers believing they comply with accessibility guidelines but then discovering that adjustments and updates need to be made as they introduce new features or as new accessibility hardware or software are adopted by end-users exemplifes Bennett et al's observation that "access requires continuous work" [7].…”

Sensing technologies that implicitly and explicitly mediate digital experiences are an increasingly pervasive part of daily living; it is vital to ensure that these technologies work appropriately for people with physical disabilities. We conducted on online survey with 40 adults with physical disabilities, gathering open-ended descriptions about respondents' experiences with a variety of sensing systems, including motion sensors, biometric sensors, speech input, as well as touch and gesture systems. We present fndings regarding the many challenges status quo sensing systems present for people with physical disabilities, as well as the ways in which our participants responded to these challenges. We conclude by refecting on the signifcance of these fndings for defning a future research agenda for creating more inclusive sensing systems. CCS CONCEPTS • Human-centered computing → Ubiquitous and mobile computing; Accessibility; • Computing methodologies → Artifcial intelligence; • Social and professional topics → People with disabilities.
