“…While the adoption of navigation technology among people with visual impairments suggests that such technologies are helpful, we still have limited understanding of how people choose navigation technologies and use them in their everyday lives. navigation technologies to support blind users, but most prior research focuses on a singular viewpoint, whether the sensory output method (e.g., sound [16]), navigation scenario (e.g., unfamiliar indoor environment [9]), or suitability of specific technology (e.g., smartphone accelerometers [4]). Absent in this work are the role that individual differences play in choosing and using navigation technology; we should expect that people with vision impairments are individuals, with individual preferences, and not simply an aggregate collection of users.…”

Personal navigation tools have greatly impacted the lives of people with vision impairments. As people with vision impairments often have different requirements for technology, it is important to understand users' ever-changing needs. We conducted a formative study exploring how people with vision impairments used technology to support navigation. Our findings from interviews with 30 adults with vision impairments included insights about experiences in Orientation & Mobility (O&M) training, everyday navigation challenges, helpful and unhelpful technologies, and the role of social interactions while navigating. We produced a set of categorical data that future technologists can use to identify user requirements and usage scenarios. These categories consist of Personality and Scenario attributes describing navigation behaviors of people with vision impairments. We demonstrate the usefulness of these attributes by introducing navigation-style personas backed by our data. This work demonstrates the complex choices individuals with vision impairments undergo when leaving their home, and the many factors that affect their navigation b ehavior.

“…Although widespread solutions are still not a reality indoors, there are several eforts to support indoor localization and blind navigation assistance [17,57]. There is an increasing tendency for approaches where users do not require any hardware besides their own devices, for instance by making use of smartphone sensors [16,21]. In addition, camera-based approaches can use the user's (or a specialized) device to guide them to a particular target [4,18,41] or to detect and avoid obstacles [19,39,49,62,66].…”

People with visual impairments often have to rely on the assistance of sighted guides in airports, which prevents them from having an independent travel experience. In order to learn about their perspectives on current airport accessibility, we conducted two focus groups that discussed their needs and experiences in-depth, as well as the potential role of assistive technologies. We found that independent navigation is a main challenge and severely impacts their overall experience. As a result, we equipped an airport with a Bluetooth Low Energy (BLE) beacon-based navigation system and performed a real-world study where users navigated routes relevant for their travel experience. We found that despite the challenging environment participants were able to complete their itinerary independently, presenting none to few navigation errors and reasonable timings. This study presents the frst systematic evaluation posing BLE technology as a strong approach to increase the independence of visually impaired people in airports.

“…Previous indoor navigation designs can be broadly grouped into three categories: dead-reckoning (e.g., Foxlin 2005;Li et al 2012); sensor-based (e.g., Hub et al 2004);and, beacon-based (e.g., Chawathe 2008;Buchanan 2010). Each of these solutions have their own trade-offs as summarised by Fallah et al (2012Fallah et al ( , 2013. Most notably, deadreckoning techniques degrade in accuracy over time as errors accumulate; beacon-based versions often involve large-scale augmentation of the physical environment; and, sensorbased approaches require considerable computational power and custom hardware.…”

This paper describes an approach to using physical-digital appropriation for navigation, piggybacking off the humble, ubiquitous barcode to facilitate cheap, scalable indoor wayfinding. We illustrate the technique by describing a prototype interface for navigating to specific books within a library. Our design-BookMark-provides visitors to the library with a detailed map to any desired book by simply scanning the barcode on the back of any other book in the library. After describing in detail how our technique is achieved, we move on to show its effectiveness via an in-situ experiment in which we compare our design to standard methods of library navigation. We then present the results of a longitudinal evaluation where we deploy the BookMark application to library visitors for a period of 24 months. We conclude with a discussion of our overall results, what our design means for other pervasive infrastructures, and how best to design for the future of physical-digital appropriation.
