Wayfinding and Navigation for People with Disabilities Using Social Navigation Networks
To achieve safe and independent mobility, people usually depend on published information, prior experience, the knowledge of others, and/or technology to navigate unfamiliar outdoor and indoor environments. Today, due to advances in various technologies, wayfinding and navigation systems and services are commonplace and are accessible on desktop, laptop, and mobile devices. However, despite their popularity and widespread use, current wayfinding and navigation solutions often fail to address the needs of people with disabilities (PWDs). We argue that these shortcomings are primarily due to the ubiquity of the compute-centric approach adopted in these systems and services, where they do not benefit from the experience-centric approach. We propose that following a hybrid approach of combining experience-centric and compute-centric methods will overcome the shortcomings of current wayfinding and navigation solutions for PWDs
The Shortest Path to Happiness: Recommending Beautiful, Quiet, and Happy Routes in the City
When providing directions to a place, web and mobile mapping services are all
able to suggest the shortest route. The goal of this work is to automatically
suggest routes that are not only short but also emotionally pleasant. To
quantify the extent to which urban locations are pleasant, we use data from a
crowd-sourcing platform that shows two street scenes in London (out of
hundreds), and a user votes on which one looks more beautiful, quiet, and
happy. We consider votes from more than 3.3K individuals and translate them
into quantitative measures of location perceptions. We arrange those locations
into a graph upon which we learn pleasant routes. Based on a quantitative
validation, we find that, compared to the shortest routes, the recommended ones
add just a few extra walking minutes and are indeed perceived to be more
beautiful, quiet, and happy. To test the generality of our approach, we
consider Flickr metadata of more than 3.7M pictures in London and 1.3M in
Boston, compute proxies for the crowdsourced beauty dimension (the one for
which we have collected the most votes), and evaluate those proxies with 30
participants in London and 54 in Boston. These participants have not only rated
our recommendations but have also carefully motivated their choices, providing
insights for future work.Comment: 11 pages, 7 figures, Proceedings of ACM Hypertext 201
Literacy Access through Storytime: An Ethnographic Study of Public Library Storytellers in a Low-Income Neighborhood
While early literacy achievement continues to be stratified by social class in the United States, public libraries often offer programs such as “storytime” in order to bolster the literacy development of youth in their communities. The purpose of the present ethnographic study was to explore how storytellers recruited and maintained participation in this free literacy program in a lower-income neighborhood. Via participant observations, semi-structured interviews, and artifact collection, storytellers recruited new patrons to storytime by (1) appealing to community members to enter the physical space of the library and (2) appealing to library patrons to attend storytime. Once patrons attended storytime, storytellers acted in order to maintain storytime attendance by (1) facilitating meaningful learning experiences, (2) fostering enjoyment through participation, (3) developing nurturing relationships, and (4) offering flexibility in storytime expectations. By exploring a contextualized account of the work of storytellers, the findings suggest important avenues through which public programs may contribute to more equitable access to literacy learning
Co-production as a route to employability: Lessons from services with lone parents
Policy‐makers claim to support personalized approaches to improving the employability of disadvantaged groups. Yet, in liberal welfare states, mainstream activation programmes targeting these groups often deliver standardized, low‐quality services. Such failures may be related to a governance and management regime that uses tightly defined contracting and performance targets to incentivize (mainly for‐profit) service providers to move people into any job as quickly as possible. This article draws on evidence from third sector/public sector‐led services in Scotland to discuss an alternative approach. These services co‐produced personalized support in partnership with disadvantaged service users (in this case vulnerable lone parents). We suggest that, in this case, street‐level co‐production and personalization were facilitated by co‐governance and co‐management in the design and organization of provision. We conclude by identifying lessons for future employability services
Syrian Refugees and the Digital Passage to Europe: Smartphone Infrastructures and Affordances
This research examines the role of smartphones in refugees’ journeys. It traces the risks and possibilities afforded by smartphones for facilitating information, communication, and migration flows in the digital passage to Europe. For the Syrian and Iraqi refugee respondents in this France-based qualitative study, smartphones are lifelines, as important as water and food. They afford the planning, navigation, and documentation of journeys, enabling regular contact with family, friends, smugglers, and those who help them. However, refugees are simultaneously exposed to new forms of exploitation and surveillance with smartphones as migrations are financialised by smugglers and criminalized by European policies, and the digital passage is dependent on a contingent range of sociotechnical and material assemblages. Through an infrastructural lens, we capture the dialectical dynamics of opportunity and vulnerability, and the forms of resilience and solidarity, that arise as forced migration and digital connectivity coincide
