We explore large language model (LLM) responses that may negatively impact the transgender and nonbinary (TGNB) community and introduce the Transing Transformers Toolkit, T^3, which provides resources for identifying such harmful response behaviors. The heart of T^3 is a community-centred taxonomy of harms, developed in collaboration with the TGNB community, which we complement with, amongst other guidance, suggested heuristics for evaluation. To develop the taxonomy, we adopted a multi-method approach that included surveys and focus groups with community experts. The contribution highlights the importance of community-centred approaches in mitigating harm, and outlines pathways for LLM developers to improve how their models handle TGNB-related topics.

We present a cross-cultural diary study with 64 transgender (trans) and non-binary adults in Mexico, the U.S., and India, to understand experiences keeping track of and managing aspects of personal health and well-being. Based on a reflexive thematic analysis of diary data, we highlight sociotechnical interactions that shape how trans and non-binary people track and manage aspects of their health and well-being. Specifically, we surface the ways in which trans and non-binary people infrastructure forms of care, by assembling together elements of informal social ecologies, formalized knowledge sources, and self-reflective media. We examine the forms of precarity that interact with care infrastructure and shape management of health and well-being, including management of gender identity transitions. We discuss the ways in which our findings extend knowledge at the intersection of technology and marginalized health needs, and conclude by arguing for the importance of a research agenda to move toward TGNB-inclusive design.

As we design increasingly complex systems, we run up against fundamental limitations of human imagination. To support practice, it becomes essential to use authentic data and algorithms as design materials to augment designers' intuitions. Recent work has explored some dimensions of using data as a design material, suggesting the contours of a new space of design and prototyping methods. In this paper, we present Replay Enactments (REs, an extension of the User Enactments methods that uses data replay as a boundary object, making complex system behavior tangible to designers and stakeholders. We reflect on a set of case studies that have instantiated REs in diverse ways and discuss trade-offs between different ways of using data replays in design. We conclude by highlighting opportunities and challenges for future work.

As people generate large quantities of heterogeneous data across their lifetimes, there is an opportunity to consider how we might build digital systems that leverage this information to help people communicate aspects of their life for which they would like to be remembered without the need to directly assign or pass on this information to another person. We present a study that leverages existing research and the use of an online design probe to explore how people think about how they'll be remembered, and how digital systems and information might help shape how people look back on and interpret people's lives after they've passed away. Findings from this work articulate specific challenges and opportunities for building systems to support people's ability to engage with experiences and memories through their digital materials.

Personal informatics systems are becoming increasingly prevalent as their price, form, and ease of use improves. Though these systems offer great potential value to users, many systems are hampered by issues that limit their ability to foster engagement, and people often abandon use of these systems without garnering meaningful outcomes. While continued use of these systems is not necessary for all people, there is an opportunity to better support people working towards achievement-based goals.

Death is an inevitable part of life, but digital systems have been slow to address the complex issues that arise when a person passes away. As digital systems have become an increasingly important part people's lives, so too have these systems begun to play a role in a number of practices related to death, such as legacy-making, bereavement, and remembrance. In this paper, we conduct a survey of seventy-five digital systems designed to support these practices. Building on prior work, we analyzed these systems to derive findings that articulate how digital technologies reflect how people think about and engage with death. Based on these findings, we generated strategies designed to help system designers grapple with the complex needs that result from navigating death online.

People accumulate huge assortments of virtual possessions, but it is not yet clear how systems and system designers can help people make meaning from these large archives. Early research in HCI has suggested that people generally appear to value their virtual things less than their material things, but theory on material possessions does not entirely explain this difference. To investigate if changes to the form and behavior of virtual things may surface valued elements of a virtual archive, we designed a technology probe that selected snippets from old emails and mailed them as physical postcards to participating households. The probe uncovered features of emails that trigger meaningful reflection, and how contextual information can help people engage in reminiscence. Our study revealed insights about how materializing virtual possessions influences factors shaping how people draw on, understand, and value those possessions. We conclude with implication and strategies for aimed at supporting people in having more meaningful interactions and experiences with their virtual possessions.

As people increasingly turn to digital channels to share, store, and reflect on their lives and experiences, the processes by which they manage the diverse collection of information generated over the course of their lives are changing. These processes, once a matter of hands-on curation and personal meaning making, are now deeply rooted in interactions with digital systems. In this work, we drew from prior research from personalization, memory, and information management to create four interactive, provocative systems. Through sessions with 12 adults from Pittsburgh, PA we used a combination of these systems and interviews to examine how systems might play a role in the near and long term resurfacing of personal and familial digital information. Findings point to an opportunity to create systems that can openly mediate the curation and transmission of digital content, and ways to draw meaning from the differences between how systems and people recall and represent their experiences.

The creation of a personal legacy is a process through which information, values, and memories are passed down to future generations. This process is inherently subjective, both as a curated collection of the elements of one's life, and as an evolving form of remembrance that is subject to the interpretations of those to whom it is left. Based on directed storytelling sessions with 14 adults from a large Midwestern city in the USA, we explore users' perceptions of how their use of digital systems and information will impact how their lives are interpreted and reflected upon by their families and by future generations. Our findings describe nuances regarding how shifting notions about technological systems and the long-term accessibility of digital information impact the ways in which we share, and subsequently manage, information online. This work, explored here in the context of legacy, exposes opportunities to help users engage with their digital information through the curation of meaningful records, the dispossession of digital debris, and a reexamination of how digital systems and services influence the accessibility and lifespan of digital information.

How do people keep track of their money? In this paper we present a preliminary scoping study of how 14 individuals in the San Francisco Bay Area earn, save, spend and understand money and their personal and family finances. We describe the practices we developed for exploring the sensitive topic of money, and then discuss three sets of findings. The first is the emotional component of the relationship people have with their finances. Second, we discuss the tools and processes people used to keep track of their financial situation. Finally we discuss how people account for the unknown and unpredictable nature of the future through their financial decisions. We conclude by discussing the future of studies of money and finance in HCI, and reflect on the opportunities for improving tools to aid people in managing and planning their finances.

Legacy is the meaningful and complex way in which information, values, and possessions are passed on to others. As digital systems and information become meaningfully parts of people's everyday and social relationships, it is essential to develop new insights about how technology intersects with legacy and inheritance practices. We designed three interactive systems to investigate how digital materials might be passed down in the future. We conducted in-home interviews with ten parents using the systems to provoke discussion about how technology might support or complicate their existing practices. Sessions revealed parents desired to treat their digital information in ways not fully supported by technology. Findings are interpreted to describe design considerations for future work in this emerging space.

Among the billions of photos that have been contributed to online photo-sharing sites, there are many that are provocative, controversial, and deeply personal. Previous research has examined motivations for sharing images online and has identified several key motivations for doing so: expression, curation of identity, maintaining social connections, and recording experiences. However, few studies have focused on the perceived risks of posting photos online and even fewer have examined the risks associated with provocative, controversial, or deeply personal images. In our work, we used photo-elicitation interviews to explore the motivations for posting these types of images and the perceived risks of doing so. In this paper, we describe our findings from those interviews.

This project represents a first step towards bridging the gap between HCI and cognition research. Using functional near-infrared spectroscopy (fNIRS), we introduce tech-niques to non-invasively measure a range of cognitive workload states that have implications to HCI research, most directly usability testing. We present a set of usability experiments that illustrates how fNIRS brain measurement provides information about the cognitive demands placed on computer users by different interface designs.
