Outdoor navigation remains a challenging activity for People with Visual Impairments (PVI). Having examined the current literature, we conclude that there are very few publications providing a nuanced understanding of how PVI undertake a journey in an outdoor environment and what are their main challenges and obstacles. This is a critical step towards developing robust solutions that meet the requirements of this user group. We undertook a questionnaire-based study with the National Council for the Blind of Ireland (NCBI) and 49 PVI. According to the feedback from our questionnaire, current journey navigation apps do not provide PVI with sufficient information about traffic lights, crossroads, and physical obstacles to support a satisfactory interaction. Our study reveals key aspects of how PVI interact with outdoor navigation applications. Critical gaps exist, for example, over 63% of respondents indicated they had suffered an injury on at least one previous occasion when navigating outdoors. Based on the questionnaire feedback, we present a solution covering the main aspects of outdoor navigation for PVI. Our work aims to contribute to the improvement of outdoor navigation applications for PVI in the future.

“…Similarly, the factors related to the adoption of mobile learning in higher education such as trust, characters and personal qualities, context, perceived usefulness of using, behavioral intention, and culture are also considered (Hamidi & Chavoshi, 2018). Since visual impairment demands clear policies of accessibility over the factors mentioned, Mishra et al (2018), have suggested an environment descriptor to give natural language descriptions of images. Tsai et al (2019) suggested the indoor special voice navigation to ensure quality and effectiveness for those with and without visual impairments, and earcons are described by McGookin (2020) as abstract tones blended to form aural messages and represent events like someone entering or departing a virtual place.…”

The purpose of this literature review is to identify, categorize, and critically appraise research papers related to mobile apps for visually impaired people in language learning. This study intended to identify the language skills, the affordances, and the limitations encountered while designing and implementing the apps. Hence, a systematic review in the Scopus database and the virtual libraries of IEEE, SAGE, ERIC, and Science Direct, adhering to the PRISMA methodology, produced 274 research papers, and after the application of the different phases, a detailed analysis was performed using 17 articles. The results revealed that Information Communication Technologies, assistive technologies, and electronic accessibility features contributed to the usability guidelines and the current evolution toward modern language learning mobile applications for visually impaired users. The revised work also revealed how writing, reading, and spelling became more demanding for this particular special need, and that grammar-based and traditional activities are replaced by other communicative approaches. The emphasis was on speaking and listening skills due to these being less demanding in terms of technical requirements. The findings of this review provide insights for instructional designers to construct inclusive language learning apps which consider the three essential dimensions needed to achieve it: technological, pedagogical and psychological, in addition to appropriate affordances necessary for both sighted and visually impaired users.

“…There are several research approaches used to help BVIP to interpret their immediate environments, such as scene recognition [ 58 ], multi-object detection [ 42 ], and scene caption [ 43 ]. Scene recognition is about classifying the image into pre-defined classe [ 58 ], while multi-object detection is to detect multiple objects on a single image [ 42 ].…”

Blind and Visually impaired people (BVIP) face a range of practical difficulties when undertaking outdoor journeys as pedestrians. Over the past decade, a variety of assistive devices have been researched and developed to help BVIP navigate more safely and independently. In addition, research in overlapping domains are addressing the problem of automatic environment interpretation using computer vision and machine learning, particularly deep learning, approaches. Our aim in this article is to present a comprehensive review of research directly in, or relevant to, assistive outdoor navigation for BVIP. We breakdown the navigation area into a series of navigation phases and tasks. We then use this structure for our systematic review of research, analysing articles, methods, datasets and current limitations by task. We also provide an overview of commercial and non-commercial navigation applications targeted at BVIP. Our review contributes to the body of knowledge by providing a comprehensive, structured analysis of work in the domain, including the state of the art, and guidance on future directions. It will support both researchers and other stakeholders in the domain to establish an informed view of research progress.
