People assume different and important roles within social networks. Some roles have received extensive study: that of influencers who are well-connected, and that of brokers who bridge unconnected parts of the network. However, very little work has ...

AI is becoming increasingly integrated in common technologies, which suggests that learning experiences for audiences seeking a "casual" understanding of AI-i.e. understanding how a search engine works, not necessarily understanding how to program one-is ...

This paper explores the potential of distributed emulation networks to support research and pedagogy into historical and sociotechnical aspects of software. Emulation is a type of virtualization that re-creates the conditions for a piece of legacy ...

Over the past few years, in-home smart technologies have dramatically increased and changed. This paper aims to investigate how families of different socioeconomic status use or forgo the use of smart devices, specifically smart speakers and smart ...

Capturing human annotators' subjective responses in image annotation has become crucial as vision-based classifiers expand the range of application areas. While there has been significant progress in image annotation interface design in general, ...

Live streaming refers to the broadcast of real-time videos, allowing people to have synchronous interactions. While researchers' interest in live streaming has increased recently, the accessibility of live streaming for people with visual impairments is ...

The post-college transition is a critical period where individuals experience unique challenges and stress before, during, and after graduation. Individuals often use social media to discuss and share information, advice, and support related to post-...

People with multiple chronic conditions (MCC) need support to understand and articulate how their personal values relate to their health and health care. We developed three prototypes for supporting reflection on values and health and tested them in a ...

Social presence is known to be important for distance education, and a common approach in online classes is to provide chat boxes and forums to provide the social presence. In such a class, however, learners must explicitly act beyond their normal ...

Software bots are used to streamline tasks in Open Source Software (OSS) projects' pull requests, saving development cost, time, and effort. However, their presence can be disruptive to the community. We identified several challenges caused by bots in ...

The goal of this study was to examine the work practices of behavioral health professionals with a view towards designing interactive systems to support their work. We conducted a qualitative workplace study, including in situ observations and semi-...

In two studies, we investigate how users choose virtual backgrounds and how these backgrounds influence viewers' impressions. In Study 1, we created a web prototype allowing users to apply different virtual backgrounds to their camera views and asked ...

During crises such as the COVID-19 pandemic, people spontaneously initiate support groups, while established organizations like soccer clubs set non-regular goals, both offering help. Interested in the coordination of such help and potential challenges ...

Algorithms in online platforms interact with users' identities in different ways. However, little is known about how users understand the interplay between identity and algorithmic processes on these platforms, and if and how such understandings shape ...

Built-in pervasive cameras have become an integral part of mobile/wearable devices and enabled a wide range of ubiquitous applications with their ability to be "always-on". In particular, life-logging has been identified as a means to enhance the quality ...

The COVID-19 pandemic has dramatically shifted family life across home, work, and education, especially families from nondominant groups. As schools and other educational programs moved online, parents became the primary facilitators for their children's ...

Automatic emotion recognition (ER)-enabled wellbeing interventions use ER algorithms to infer the emotions of a data subject (i.e., a person about whom data is collected or processed to enable ER) based on data generated from their online interactions, ...

An increasing number of people around the world are forced to leave their homes due to the climate catastrophe, regional conflict or poverty. In their new host countries however, refugees and migrants are frequently met by a wide range of challenges, ...

Social media provides the means by which extremist social movements, such as white supremacy and anti-LGBTQ, thrive online. Yet, we know little about the roles played by the participants of such movements. In this paper, we investigate these participants ...

Data scientists often collaborate with clients to analyze data to meet a client's needs. What does the end-to-end workflow of a data scientist's collaboration with clients look like throughout the lifetime of a project? To investigate this question, we ...

With the rapid development of smart devices and high-quality wireless technologies, mobile crowdsourcing (MCS) has been drawing increasing attention with its great potential in collaboratively completing complicated tasks on a large scale. A key issue ...

Augmented Reality (AR) applications can enable geographically distant users to collaborate using shared video feeds or interactive 3D holograms, and may be particularly useful in the socially distant context of the Covid-19 pandemic. However, a good user ...

The COVID-19 pandemic has forced the transition of workflows across sectors to digital platforms. In education settings, stakeholders previously reluctant to integrate computing technology in the classroom now find themselves with little choice but to ...

Large-scale data systems play a central role in how state bureaucracies come to know and manage citizens. Such systems are endemically uneven in implementation, producing distributed and exclusionary consequences that are among their most important ...

When toxic online communities on mainstream platforms face moderation measures, such as bans, they may migrate to other platforms with laxer policies or set up their own dedicated websites. Previous work suggests that within mainstream platforms, ...

Data is a crucial component of machine learning. The field is reliant on data to train, validate, and test models. With increased technical capabilities, machine learning research has boomed in both academic and industry settings, and one major focus has ...

Content moderation systems for social media have had numerous issues of bias, in terms of race, gender, and ability among many others. One proposal for addressing such issues in automated decision making is by designing for contestability, whereby users ...

Crowdsourcing markets provide workers with a centralized place to find paid work. What may not be obvious at first glance is that, in addition to the work they do for pay, crowd workers also have to shoulder a variety of unpaid invisible labor in these ...

Stairlifts are a widely-used technology in the home that help people with mobility issues to go up and down stairs. However, it is unclear how stairlifts are experienced by all household members and what this understanding implies for home healthcare ...
