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 portfolio of HCI research on assistive technologies (AT), few...

Twenty BPS people (9 female) had varying levels of residual vision; 50% had total blindness, while the other 50% had vision varying from light perception to partial sightedness; 70% had congenital vision impairments (Table 3). ...Context 2

... These semistructured interviews were designed to address three issues: how blind and partially sighted persons understand space, how they use these representations to travel, and the implications in their journey of aids, assistance, and mobility training. In the same way, Bandukda et al. [93] conducted semi-structured interviews conducted with twenty UBVI participants and eight mobility and orientation trainers. Their goals were to learn about orientation and mobility tools, give UBVI training on orientation and mobility technology, change personal and social circumstances, and evaluate social influences. ...
... Their goals were to learn about orientation and mobility tools, give UBVI training on orientation and mobility technology, change personal and social circumstances, and evaluate social influences. The aforementioned questionnaires and interviews [87]- [93] are focused on particular facets of the UBVI navigation activity, which is crucial to fully comprehend these facets. However, none of them covers critical aspects of the journey such as crossing a road and the understanding VOLUME 4, 2016 surrounding visual features are not discussed. ...
Outdoor navigation remains a challenging activity for people with visual impairment. Having examined the current literature, we conclude that there are very few publications providing a nuanced understanding of how PBVI undertake a journey in an outdoor environment and what their main challenges and obstacles are. 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 UBVI. According to the feedback from our questionnaire, current journey navigation apps do not provide sufficient information about traffic lights, crossroads, and physical obstacles to support satisfactory interaction. Our study reveals key aspects of how UBVI interact with outdoor navigation applications. Critical gaps exist, with over 63% of respondents indicating 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 UBVI. Our work aims to contribute to the improvement of interaction between UBVI and outdoor navigation applications in the future.
