2025 Understanding Young People's Creative Goals with Augmented Reality
abstract
Young people are major consumers of Augmented Reality (AR) tools like Pokémon GO, but they rarely engage in creating these experiences. Creating with technology gives young people a platform for expressing themselves and making social connections. However, we do not know what young people want to create with AR, as existing AR authoring tools are largely designed for adults. To investigate the requirements for an AR authoring tool, we ran eight design workshops with 17 young people in Argentina and the United States that centered on young people's perspectives and experiences. We identified four ways in which young people want to create with AR, and contribute the following design implications for designers of AR authoring tools for young people: (1) Blending imagination into AR scenarios to preserve narratives, (2) Making traces of actions visible to foster social presence (3) Exploring how AR artifacts can serve as invitations to connect with others, and (4) Leveraging information asymmetry to encourage learning about the physical world.

2024 "I Deleted It After the Overturn of Roe v. Wade": Understanding Women's Privacy Concerns Toward Period-Tracking Apps in the Post Roe v. Wade Era
abstract
The overturn of Roe v. Wade has taken away the constitutional right to abortion. Prior work shows that period-tracking apps’ data practices can be used to detect pregnancy and abortion, hence putting women at risk of being prosecuted. It is unclear how much women know about the privacy practices of such apps and how concerned they are after the overturn. Such knowledge is critical to designing effective strategies for stakeholders to enhance women’s reproductive privacy. We conducted an online 183-participant vignette survey with US women from states with diverse policies on abortion. Participants were significantly concerned about the privacy practices of the period-tracking apps, such as data access by law enforcement and third parties. However, participants felt uninformed and powerless about risk mitigation practices. We provide several recommendations to enhance women’s privacy awareness toward their period-tracking practices.

2024 "Voices Help Correlate Signs and Words": Analyzing Deaf and Hard-of-Hearing (DHH) TikTokers' Content, Practices, and Pitfalls
abstract
Video-sharing platforms such as TikTok have offered new opportunities for d/Deaf and hard-of-hearing (DHH) people to create public-facing content using sign language – an integral part of DHH culture. Besides sign language, DHH creators deal with a variety of modalities when creating videos, such as captions and audio. However, hardly any work has comprehensively addressed DHH creators’ multimodal practices with the lay public’s reactions taken into account. In this paper, we systematically analyzed 308 DHH-authored TikTok videos using a mixed-methods approach, focusing on DHH TikTokers’ content, practices, pitfalls, and viewer engagement. Our findings highlight that while voice features such as synchronous voices are scant and challenging for DHH TikTokers, they may help promote viewer engagement. Other empirical findings, including the distributions of topics, practices, pitfalls, and their correlations with viewer engagement, further lead to actionable suggestions for DHH TikTokers and video-sharing platforms.

2024 Understanding Parents' Perceptions and Practices Toward Children's Security and Privacy in Virtual Reality
abstract
Recent years have seen a sharp increase in the number of underage users in virtual reality (VR), where security and privacy (S&P) risks such as data surveillance and self-disclosure in social interaction have been increasingly prominent. Prior work shows children largely rely on parents to mitigate S&P risks in their technology use. Therefore, understanding parents’ S&P knowledge, perceptions, and practices is critical for identifying the gaps for parents, technology designers, and policymakers to enhance children’s S&P. While such empirical knowledge is substantial in other consumer technologies, it remains largely unknown in the context of VR. To address the gap, we conducted in-depth semi-structured interviews with 20 parents of children under the age of 18 who use VR at home. Our findings highlight parents generally lack S&P awareness due to the perception that VR is still in its infancy. To protect their children’s interactions with VR, parents currently primarily rely on active strategies such as verbal education about S&P. Passive strategies such as using parental controls in VR are not commonly used among our interviewees, mainly due to their perceived technical constraints. Parents also highlight that a multi-stakeholder ecosystem must be established towards more S&P support for children in VR. Based on the findings, we propose actionable S&P recommendations for critical stakeholders, including parents, educators, VR companies, and governments.

2023 Investigating Deaf and Hard-of-Hearing (DHH) Individuals' Online Dating Practices, Self-Presentation, and Disability Disclosure
abstract
The proliferation of online dating platforms has provided new opportunities for deaf and hard of hearing (DHH) individuals to seek, build, and maintain romantic relationships. However, challenges such as deception, harassment, and aggression widely exist, closely tied to their practices of self-presentation and disability disclosure. Yet, these practices of DHH individuals in online dating communities remain largely unknown. Our study presents a preliminary qualitative analysis of 1,200 posts from a leading DHH online dating community. Our findings reveal that DHH individuals hesitate to reveal their disability while actively disclosing their relationship challenges, especially with respect to hearing-DHH relationships. We have also identified significant research gaps in understanding online DHH dating activities, calling for future research to make online dating environments more inclusive for DHH individuals.

2023 DreamVR: Curating an Interactive Exhibition in Social VR Through an Autobiographical Design Study
abstract
Virtual exhibitions have long been regarded as an extension of information delivery for physical exhibitions. However, what virtual exhibitions can offer audiences as a novel experience independently from physical exhibitions has been largely unexplored. In this study, we aim to understand the promises and challenges of experiencing and curating exhibitions in VR by interviewing nine expert curators. Drawing from expert insights, we summarized a set of design guidelines to inform what we can learn and adapt from physical exhibitions when curating in VR. Then, using an autobiographical design approach, we curated an interactive exhibition in VRChat to explore novel interaction techniques. We also hosted an open tour guide in the user study to validate our design guidelines with thirty participants. Results show that our approach of curating an exhibition in VRChat provided the participants with engaging and novel experiences interacting with the exhibits and other audiences.

2023 "I Am a Mirror Dweller": Probing the Unique Strategies Users Take to Communicate in the Context of Mirrors in Social Virtual Reality
abstract
Increasingly popular social virtual reality (VR) platforms like VRChat created new ways for people to interact with each other, generating dedicated user communities with unique idioms of socializing in an alternative world. In VRChat, users frequently gather in front of mirrors en masse during online interactions. Understanding how user communities deal with the mirror’s unique interactions can generate insights for supporting communication in social VR. In this study, we investigated the mirror’s synergistic effect with avatars on behaviors and dedicated user conversational performance. Qualitative findings indicate that avatar-mediated communication through mirrors provides functions like ensuring synchronization of incarnations, increasing immersion, and enhancing idealized embodiment to express bolder behaviors anonymously. Quantitative studies show that while mirrors improve self-perception, it has a potentially adverse effect on conversational performance, similar to the role of self-viewing in video conferencing. Studying how users interact with mirrors in an immersive environment allows us to explore how digital environments affect spatialized interactions when transported from physical to digital domains.
