Human-Centered Responsible Artificial Intelligence: Current & Future Trends
In recent years, the CHI community has seen significant growth in research on
Human-Centered Responsible Artificial Intelligence. While different research
communities may use different terminology to discuss similar topics, all of
this work is ultimately aimed at developing AI that benefits humanity while
being grounded in human rights and ethics, and reducing the potential harms of
AI. In this special interest group, we aim to bring together researchers from
academia and industry interested in these topics to map current and future
research trends to advance this important area of research by fostering
collaboration and sharing ideas.Comment: To appear in Extended Abstracts of the 2023 CHI Conference on Human

Socio-geography of human mobility: a study using longitudinal mobile phone data
A relationship between peopleâs mobility and their social networks is presented based on an analysis of calling and mobility traces for one year of anonymized call detail records of over one million mobile phone users in Portugal. We find that about 80% of places visited are within just 20 km of their nearest (geographical) social tiesâ locations. This figure rises to 90% at a âgeo-social radiusâ of 45 km. In terms of their travel scope, people are geographically closer to their weak ties than strong ties. Specifically, they are 15% more likely to be at some distance away from their weak ties than strong ties. The likelihood of being at some distance from social ties increases with the population density, and the rates of increase are higher for shorter geo-social radii. In addition, we find that area population density is indicative of geo-social radius where denser areas imply shorter radii. For example, in urban areas such as Lisbon and Porto, the geo-social radius is approximately 7 km and this increases to approximately 15 km for less densely populated areas such as Parades and Santa Maria da Feira
"...when you're a stranger":Evaluating safety perceptions of (un)familiar urban places
What makes us feel safe when walking around our cities? Previous
research has shown that our perception of safety strongly depends
on characteristics of the built environment; separately, research has
also shown that safety perceptions depend on the people we encounter
on the streets. However, it is not clear how the two relate
to one another. In this paper, we propose a quantitative method
to investigate this relationship. Using an online crowdâsourcing
approach, we collected 5452 safety ratings from over 500 users
about images showing various combinations of built environment
and people inhabiting it. We applied analysis of covariance (ANCOVA)
to the collected data and found that familiarity of the scene
is the single most important predictor of our sense of safety. Controlling
for familiarity, we identified then what features of the urban
environment increase or decrease our safety perception

Owning a Home: New Opportunities and Challenges for Low-Income Women
In recent years, policy initiatives at the federal, state and local levels have fostered innovative programs to promote and support low-to-moderate income individuals and families in achieving homeownership. However, the sustainability of homeownership among this group is an area of concern as default and foreclosure rates have increased and are expected to grow. This exploratory study examined the housing experience of 11 female, first-time low-to-moderate income homeowners who completed a homebuyer education program. Their experiences suggest that sustaining homeownership, while problematic, provides immeasurable positive gains within themselves and for their families. Strategies of how they cope with the challenges inherent in maintaining this asset are discussed. Implications for supporting these tenuous housing situations are offered
