“…As outdoor navigation is heavily dependent on route learning through landmarks and clues in O&M training, the BPS participants found it difficult to navigate new and unfamiliar routes. Despite a significant body of AT research focuses on navigation for BPS people, the availability of commercial AT for route familiarization is limited, therefore, BPS people often rely on sighted help for assistance in unfamiliar outdoor environments [30,79]. As noted in previous research, having prior understanding of the route and surroundings is essential for independent mobility [4,38,79].…”

Figure 1: Factors that influence self-efficacy belief of blind and partially sighted people Orientation and mobility (O&M) training provides essential skills and techniques for safe and independent mobility for blind and partially sighted (BPS) people. The demand for O&M training is increasing as the number of people living with vision impairment increases. Despite the growing research on O&M assistive technologies (AT), few studies have examined the experiences of BPS people during O&M training, including the use of technology to aid O&M training. To address this gap, we conducted semistructured interviews with 20 BPS people and 8 Mobility and Orientation Trainers (MOT). The interviews were thematically analysed and organised into four overarching themes: Tools and Strategies for O&M training, Technology Use in O&M Training, Changing Personal and Social Circumstances, and Social Influences. Our findings show that the self-efficacy belief evolves over time and across different circumstances, therefore, requiring ongoing O&M support for BPS people. We discuss opportunities for accessibility research in multimodal technologies to increase access to and effectiveness of O&M training.

“…Independent navigation for people with visual impairments is considered a major challenge, drawing significant attention from the research communities in both HCI and AI [23]. Here, AI is often used to solve a functional task, where the user follows instructions to successfully reach a destination.…”

“…For example, increased attention has been given to designing and developing AI-enabled AT to aid independent navigation for people with visual impairments. In this research, much effort has been dedicated to providing the individual with wayfinding guidance and complimentary information about the physical features in an environment such as one's proximity to obstacles, curbs, hazards and landmarks [3,22,23,29,39,42].…”

Prior work on AI-enabled assistive technology (AT) for people with visual impairments (VI) has treated navigation largely as an independent activity. Consequently, much effort has focused on providing individual users with wayfinding details about the environment, including information on distances, proximity, obstacles, and landmarks. However, independence is also achieved by people with VI through interacting with others, such as in collaboration with sighted guides. Drawing on the concept of interdependence, this research presents a systematic analysis of sighted guiding partnerships. Using interaction analysis as our primary mode of data analysis, we conducted an empirical, qualitative study with 4 couples, each made up of person with a vision impairment and their sighted guide. Our results show how pairs used interactional resources such as turn-taking and body movements to both co-constitute a common space for navigation, and repair moments of rupture to this space. This work is used to present an exemplary case of interdependence and draws out implications for designing AI-enabled AT that shifts the emphasis away from independent navigation, and towards the carefully coordinated actions between people navigating together.CCS Concepts: • Human-centered computing → Accessibility; Accessibility technologies; Accessibility design and evaluation methods; Empirical studies in accessibility;
