2026 Surveilling Suitability: How AI Hiring Interviews Impact Job Seekers with Disabilities
abstract
AI hiring interviews, asynchronous video recording platforms that use AI to assess candidate suitability, are increasingly used by employers to streamline hiring processes. These platforms often promise to standardize assessments and mitigate subjective biases in hiring decisions. Yet, little is known about how these technologies are perceived and experienced by people with disabilities, a group historically underrepresented in the workforce and particularly vulnerable to injustices perpetuated by technology. To address this gap, we conducted focus groups and semi-structured interviews with 19 people with disabilities. We found that people with disabilities perceive and experience discrimination by AI hiring interviews that: 1) center normative characteristics, 2) exacerbate information asymmetries, 3) undermine autonomy, and 4) intrude on privacy. We use the analytical frame of surveillance to interrogate the role of AI in reconfiguring social relations between job seekers and employers. We discuss implications of our work for design and policy.

2025 Accessibility Research Across Borders: Collaboration and Community Building in Accessibility and ICTD Research
abstract
Collaboration and community building are crucial for equitable participation in research, especially in disability and accessibility research fields.Engaging with communities of disabled individuals helps understand their unique challenges, expectations, and needs, which should be reflected in assistive technology design.However, a gap exists between research in resource-rich societies and the practices of low-resource settings, where socio-economic and infrastructural constraints are often overlooked.Conversely, the innovation and sustainable solutions in these settings are often

2024 Help and The Social Construction of Access: A Case-Study from India
abstract
A goal of accessible technology (AT) design is often to increase independence, i.e., to enable people with disabilities to accomplish tasks on their own without help. Recent work challenges this view by recognizing the role of ‘help’ in addressing the access needs of people with disabilities. However, empirical evidence examining help is limited to the Global North; we address this gap using a case study of how people with visual impairments (PVI) navigate indoor environments in India. Using interviews with PVI and their companions and a video-diary study, we find that help is a key practice that PVI use to navigate indoor environments. We uncover how help is a situated phenomenon shaped by socio-material and cultural factors unique to the Indian context. We discuss the value of help in the context of broader HCI and Accessibility literature on mixed-ability and collaborative interactions. We also discuss implications our findings on help have for AT design.

2024 Human technology intermediation to reduce cognitive load: understanding healthcare staff members' practices to facilitate telehealth access in a Federally Qualified Health Center patient population
abstract
OBJECTIVES: The aim of this study was to investigate how healthcare staff intermediaries support Federally Qualified Health Center (FQHC) patients' access to telehealth, how their approaches reflect cognitive load theory (CLT) and determine which approaches FQHC patients find helpful and whether their perceptions suggest cognitive load (CL) reduction. MATERIALS AND METHODS: Semistructured interviews with staff (n = 9) and patients (n = 22) at an FQHC in a Midwestern state. First-cycle coding of interview transcripts was performed inductively to identify helping processes and participants' evaluations of them. Next, these inductive codes were mapped onto deductive codes from CLT. RESULTS: Staff intermediaries used 4 approaches to support access to, and usage of, video visits and patient portals for FQHC patients: (1) shielding patients from cognitive overload; (2) drawing from long-term memory; (3) supporting the development of schemas; and (4) reducing the extraneous load of negative emotions. These approaches could contribute to CL reduction and each was viewed as helpful to at least some patients. For patients, there were beneficial impacts on learning, emotions, and perceptions about the self and technology. Intermediation also resulted in successful visits despite challenges. DISCUSSION: Staff intermediaries made telehealth work for FQHC patients, and emotional support was crucial. Without prior training, staff discovered approaches that aligned with CLT and helped patients access technologies. Future healthcare intermediary interventions may benefit from the application of CLT in their design. Staff providing brief explanations about technical problems and solutions might help patients learn about technologies informally over time. CONCLUSION: CLT can help with developing intermediary approaches for facilitating telehealth access.

2023 Advocacy as Access Work: How People with Visual Impairments Gain Access to Digital Banking in India
abstract
Research in accessibility and assistive technology often assumes that technology is within easy reach, that is, people with disabilities are able to obtain technologies so long as they are accessible. As a result, less is understood about the challenges that people with disabilities face in obtaining technology in the first place and how they work around these challenges. We reduce this gap by examining the technology access challenges of people with visual impairments in India in the context of digital banking. Through a qualitative study consisting of 30 interviews, we find that participants routinely encountered social and technical challenges that made it difficult to access and use digital banking. To address these challenges, people with visual impairments engaged in advocacy work which consisted of five dimensions: 1) creating awareness, 2) demonstrating competence, 3) escalation, 4) gathering support, and 5) seeking sighted help. We expand on the idea of advocacy as a form of access work performed by people with visual impairments to secure and maintain access to digital banking.

2022 Trust, Reciprocity, and the Role of Timebanks as Intermediaries: Design Implications for Addressing Healthcare Transportation Barriers
abstract
Millions of Americans forego medical care due to a lack of non-emergency transportation, particularly minorities, older adults, and those who have disabilities or chronic conditions. Our study investigates the potential for using timebanks—community-based voluntary services that encourage exchanges of services for “time dollars” rather than money—in interventions to address healthcare transportation barriers to seed design implications for a future affordable ridesharing platform. In partnership with a timebank and a federally qualified healthcare center (FQHC), 30 participants completed activity packets and 29 of them attended online workshop sessions. Our findings suggest that promoting trust between drivers and riders requires systems that prioritize safety and reliability; yet, there were discrepancies in the ability of the timebank and FQHC to moderate trust. We also found that timebank supports reciprocity, but healthcare transportation requires additional support to ensure balanced reciprocity. We explain these findings drawing from network closure and trust literature. Finally, we contribute design implications for systems that promote trust and facilitate relational over transactional interactions, which help to promote reciprocity and reflect participants’ values.

2021 Examining Mobility Among People Living with HIV in Rural Areas
abstract
The rise of ridesharing platforms has transformed traditional transportation, making it more accessible for getting to work and accessing grocery stores and healthcare providers, which are essential to physical and mental well-being. However, such technologies are not available everywhere. Additionally, there is a scarcity of HCI work that investigates how vulnerable populations such as rural-dwelling people with HIV face and overcome transportation barriers. To extend past research, we conducted 31 surveys and 18 interviews with people living with HIV (22 surveys, 14 interviews) and their case coordinators (9 surveys, 4 interviews) in rural areas. Contrary to past research, we found that the use of alternative vehicles, extensive support networks, and nonprofit health organizations facilitated transportation. However, distance, the lack of trust and infrastructure, stigma, and other cultural underpinnings made popular forms of urban transportation unappealing. We contextualize our findings with prior research and contribute implications for future research and design.

2021 Understanding Accessibility and Collaboration in Programming for People with Visual Impairments
abstract
There has been a growing interest in Computer-Supported Cooperative Work and Human-Computer Interaction to understand the experiences of programmers in the workplace. However, the large majority of these studies has focused on sighted programmers and, as a result, the experiences of programmers with visual impairments in professional contexts remain understudied. We address this gap by reporting on findings from semi-structured interviews with 22 programmers with visual impairments. We found that programmers with visual impairments interact with a complex ecosystem of tools and a significant part of their job entails performing work to overcome the accessibility challenges inherent in this ecosystem. Furthermore, we find that the visual nature of various programming activities impedes collaboration, which necessitates the co-creation of new work practices through a series of sociotechnical interactions. These sociotechnical interactions often require invisible work and articulation work on the part of the programmers with visual impairments.

2020 Understanding In-Situ Use of Commonly Available Navigation Technologies by People with Visual Impairments
abstract
Despite the large body of work in accessibility concerning the design of novel navigation technologies, little is known about commonly available technologies that people with visual impairments currently use for navigation. We address this gap with a qualitative study consisting of interviews with 23 people with visual impairments, ten of whom also participated in a follow-up diary study. We develop the idea of complementarity first introduced by Williams et al. [53] and find that in addition to using apps to complement mobility aids, technologies and apps complemented each other and filled in for the gaps inherent in one another. Furthermore, the complementarity between apps and other apps/aids was primarily the result of the differences in information and modalities in which this information is communicated by apps, technology and mobility aids. We propose design recommendations to enhance this complementarity and guide the development of improved navigation experiences for people with visual impairments.

2019 Understanding Trust, Transportation, and Accessibility through Ridesharing
abstract
Relatively few studies of accessibility and transportation for people with vision impairments have investigated forms of transportation besides public transportation and walking. To develop a more nuanced understanding of this context, we turn to ridesharing, an increasingly used mode of transportation. We interviewed 16 visually-impaired individuals about their active use of ridesharing services like Uber and Lyft. Our findings show that, while people with vision impairments value independence, ridesharing involves building trust across a complex network of stakeholders and technologies. This data is used to start a discussion on how other systems can facilitate trust for people with vision impairments by considering the role of conversation, affordances of system incentives, and increased agency.

2019 Cash, Digital Payments and Accessibility: A Case Study from Metropolitan India
abstract
Despite the growing interest in digitization and money in HCI and CSCW, the use of cash and digital payments by people with disabilities has received scant attention. We present findings from a qualitative study of people with visual impairments' use of cash and digital payments in metropolitan India. Using ride-hailing services as an exemplar, we find that both cash and digital payments were inaccessible to participants. We use Perry and Ferreira's "moneywork" as a theoretical framework to highlight the "added" work necessitated by this inaccessibility; that is, the work done in addition to the interactional work necessary to complete financial transactions. We argue that this "added" work is instrumental in "making" payments accessible. We discuss how ride-hailing platforms mediated collaborations between drivers and riders in relation to payments, while still making "moneywork" essential. We provide recommendations to improve the accessibility of digital payments to facilitate greater economic inclusion.

2018 Understanding the Power of Control in Autonomous Vehicles for People with Vision Impairment
abstract
Autonomy and control are important themes in design for people with disabilities. With the rise in research in autonomous vehicle design, we investigate perceived differences in control for people with vision impairments in the use of semi- and fully autonomous vehicles. We conducted focus groups with 15 people with vision impairments. Each focus group included a design component asking participants to design voice-based and tactile solutions to problems identified by the group. We contribute a new perspective of independence in the context of control. We discuss the importance of driving for blind and low vision people, describe differences in perceptions of autonomous vehicles based on level of autonomy, and the use of assistive technology in vehicle operation and information gathering. Our findings guide the design of accessible autonomous transportation systems and existing navigation and orientation systems for people with vision impairments.

2018 Entrepreneurship and the Socio-Technical Chasm in a Lean Economy
abstract
Online technologies are increasingly hailed as enablers of entrepreneurship and income generation. Recent evidence suggests, however, that even the best such tools disproportionately favor those with pre-existing entrepreneurial advantages. Despite intentions, the technology on its own seems far from addressing socio-economic inequalities. Using participatory action research, we investigated why this might be, in an intimate, close-up context. Over a 1-year period, we--a collaborative team of university researchers and residents of Detroit's East Side--worked to establish a neighborhood tour whose initial goal was to raise supplementary income and fundraise for community block clubs. We found that in addition to technical requirements, such as communication tools, a range of non-technological efforts is needed to manage projects, build self-efficacy, and otherwise support community participants. Our findings widen Ackerman's "socio-technical gap" for some contexts and offer a counterpoint to overgeneralized claims about well-designed technologies being able to address certain classes of social challenges.

2018 Support for Social and Cultural Capital Development in Real-time Ridesharing Services
abstract
Today's transportation systems and technologies have the potential to transform the ways individuals acquire resources from their social networks and environments. However, it is unclear what types of resources can be acquired and how technology could support these efforts. We address this gap by investigating these questions in the domain of real-time ridesharing systems. We present insights from two qualitative studies: (1) a set of semi-structured interviews with 13 Uber drivers and (2) a set of semi-structured interviews with 13 Uber riders. Our results show that both drivers and riders acquired and benefited from informational, emotional and instrumental resources, as well as cultural exchanges via interactions with each other and with online platforms. We argue that these interactions could support the development of social and cultural capital. We discuss our findings in the context of labor and contribute design implications for in-car social and cultural experiences and for the ways technologies such as GPS and location-based services can support the additional emotional, social, and cultural labor that drivers provide to their riders.

2018 Digital Payment and Its Discontents: Street Shops and the Indian Government's Push for Cashless Transactions
abstract
In November 2016, the Government of India banned the vast majority of the nation's banknotes in a move referred to as 'demonetization', with the stated goals of fighting corruption, terrorism, and eventually expanding digital transactions. In this study of 200 shop-keepers in Mumbai and Bengaluru, we found that cash shortage increased digital payment adoption but that digital payments fell after new banknotes became available. Digital payment adoption depended on the nature and scope of transactions, type of product sold, as well as personal factors specific to business owners such as comfort and familiarity with other digital technologies and online transactions. Using theoretical work on market and information behavior, we examined environmental pushes for technology adoption against prevalent transactional practices, trust, and control. We propose that the move toward digital payments must be framed within a larger undertaking of technology-driven modernity that drives these initiatives, rather than just the efficiency or productivity gains digital payments present.

2018 'We can go anywhere': Understanding Independence through a Case Study of Ride-hailing Use by People with Visual Impairments in metropolitan India
abstract
Ride-hailing services have received attention as part of the growing work around the sharing economy, but the focus of these studies has largely been on drivers. In this paper, we examine how ride-hailing is transforming the transportation practices of one group of passengers - people with visual impairments in metropolitan India. Through a qualitative study consisting of interviews and observations, we examined the use and impact of these services on our target population, who otherwise contend with chaotic, unreliable, and largely inaccessible modes of transportation. We found that ride-hailing services positively affects participants' notions of independence, and we tease out how independence for our participants is not just about 'doing things alone, without help' but is also situated, social and relative. Furthermore, we show how accessibility, in the case of ride-hailing in India, is a socio-technical and collaborative achievement, involving interactions between the passenger, the driver, and the technology.

2017 Uncovering the Values and Constraints of Real-time Ridesharing for Low-resource Populations
abstract
Real-time ridesharing services (e.g., Uber and Lyft) are often touted as sharing-economy leaders and dramatically lower the cost of transportation. However, how to make these services work better among low-income and transportation-scarce households, how these individuals experience these services, and whether they encounter barriers in enlisting these services is unknown. To address these questions, we onboarded 13 low-income individuals living in transportation-scarce environments to Uber as passengers. Our participants found these services to be reliable and benefited from rich social interactions with drivers; however, barriers such as cost, limited payment methods, and low digital literacy can make such services infeasible. We contribute platform designs that could lead to increased digital literacy and application transparency. To be more inclusive and to reach critical mass, we suggest that these companies foster belief in commons and community trust by coordinating with local businesses in low-resource areas with lower digital literacy.

2017 Rice Today, Roti Tomorrow: Diets and Diabetes in Urban Indian Households
abstract
In India, where diabetes is a growing concern and approximately 69 million are affected, we investigate the factors that influence diet management, a critical component of living with the disease. Taking the middle-income diabetes-affected household as our unit of analysis, we use a combination of semi-structured interviews and a design probe to understand if and how diets are monitored, tailored, and balanced. We research the various information-seeking behaviors of our participants and their culturally situated approaches to food and eating. Our findings illuminate how contextual nuances shape individuals' beliefs around dealing with diabetes and the ways in which family, friends, and broader social networks influence dietary decisions. We conclude by offering a framework of Learning-Being-Doing to inform the holistic design of technologies for managing diets and diabetes.

2017 Agency in Assistive Technology Adoption: Visual Impairment and Smartphone Use in Bangalore
abstract
Studies on technology adoption typically assume that a user's perception of usability and usefulness of technology are central to its adoption. Specifically, in the case of accessibility and assistive technology, research has traditionally focused on the artifact rather than the individual, arguing that individual technologies fail or succeed based on their usability and fit for their users. Using a mixed-methods field study of smartphone adoption by 81 people with visual impairments in Bangalore, India, we argue that these positions are dated in the case of accessibility where a non-homogeneous population must adapt to technologies built for sighted people. We found that many users switch to smartphones despite their awareness of significant usability challenges with smartphones. We propose a nuanced understanding of perceived usefulness and actual usage based on need-related social and economic functions, which is an important step toward rethinking technology adoption for people with disabilities.

2017 Changing data practices for community health workers: Introducing digital data collection in West Bengal, India
abstract
In this paper, we present our findings on the experiences of West Bengal Community Health Workers (CHWs) in transitioning from paper to tablet- and mobile-based data collection. Through qualitative interviews, usability testing and timed observations, we found that efficiency and quality of data collected were comparable between the use of tablet devices and traditional paper methods, but data collection performed on smaller mobile phone interfaces was less efficient compared to paper. There was no significant difference in the quality of data collected across all three modes. In terms of work practices, we found that while initial interactions with CHWs suggested positive feelings about switching to digital devices, in their actual practices they retained and preferred the use of paper, and had workarounds to circumvent the digital data collection process. While there were foreseeable challenges around individual user experience, such as device familiarity, and application interface flexibility, the more compelling challenge in transitioning CHWs to digital data collection was organizational. The agency of CHWs within organizations, the levels of training with both data practices and devices themselves, and the sense of comfort that the data collectors felt with the overall project emerge as important factors of attention for implementers of new data management practices.

2016 Institutional Structures and Culture in Healthcare: A Comparative Case on Health Learning
abstract
This paper describes two design approaches to health learning -- one a self-paced multimedia portal providing information about a highly specialized injury and the other an instructional aide, assisting educators in delivering content about medical practices. Both systems primarily targeted healthcare staff, namely physicians and nurses and were implemented in the United States and India respectively. Through an analysis of the contextual factors that determined the design of both systems we uncovered common threads concerning 1) social structures within hospitals and their influence on the flow of information within formal institutions 2) the role of institutional culture and its impact on learning. In conclusion we discuss some considerations to inform those intending to successfully deploy healthcare information systems designed for a western audience in a country like India while also discussing takeaways for healthcare systems in both locations.

2016 In search of missing pieces: A re-examination of trends in ICTD research
abstract
ICTD benefits from being a broad multidisciplinary field that unites researchers from a wide range of domains attempting to understand the role of ICTs in the context of social, economic and political development. As a new field of study, however, ICTD continuously grapples with epistemological differences and varying (and often evolving) notions of what counts as development, and there still exists a significant gap in outlining where the current boundaries of this field lie. In this paper we present "Missing Pieces," an ongoing research project with the primary aim of uncovering the constitution, development, growth and impact of ICTD. Through in-depth quantitative and qualitative analyses of the distribution of participation in and impact of ICTD research across places, people, institutions, organizations and funding agencies, this project will look beyond just trends, and instead focus on finding the missing pieces, i.e. what, or rather who is being left out.
