“…Similarly, the legibility of axis labels, annotations, and other text is an important consideration when designing visualizations for older adults. Reading smaller fonts grows progressively difficult with Age [JF17b] and several studies point to older adults' challenges using visualizations due to this issue [FWX*23,MSC*19,WM12]. Enlarging font size is an immediate solution for legibility issues, but may not always be feasible due to constraints such as limited screen real state (e.g., smartwatch).…”

Despite the explosive growth of the aging population worldwide, older adults have been largely overlooked by visualization research. This paper is a critical reflection on the underrepresentation of older adults in visualization research. We discuss why investigating visualization at the intersection of aging matters, why older adults may have been omitted from sample populations in visualization research, how aging may affect visualization use, and how this differs from traditional accessibility research. To encourage further discussion and novel scholarship in this area, we introduce GerontoVis, a term which encapsulates research and practice of data visualization design that primarily focuses on older adults. By introducing this new subfield of visualization research, we hope to shine a spotlight on this growing user population and stimulate innovation toward the development of aging‐aware visualization tools. We offer a birds‐eye view of the GerontoVis landscape, explore some of its unique challenges, and identify promising areas for future research.

“…Older adults were found to have more problems using existing mobile device icons than younger adults [62]. A recent study also showed that older adults might misinterpret icons and interactive elements in online visualizations [35]. Furthermore, Rock et al summarized that four icon characteristics-semantically close meaning (i.e.…”

“…Recent technologies, such as virtual and augmented reality, might also allow older adults to interact with a live remote bank teller through embodied avatars and shared visual cues. Moreover, future research could explore ways to design features that enable help-givers to draw visual guidance on older adults' phones to support them in conducting banking transactions and even support them to perform trial-and-error, which is effective for learning new technologies but is often challenging for older adults to do [34,35]. Another approach is to design a remote collaborative tool that allows help-givers to demonstrate how to complete a banking task with interactive guidance for older adults.…”

Managing finances is crucial for older adults who are retired and may rely on savings to ensure their lives' quality. As digital banking platforms (e.g., mobile apps, electronic payment) gradually replace physical ones, it is critical to understand how they adapt to digital banking and the potential frictions they experience. We conducted semi-structured interviews with 16 older adults in China, where the aging population is the largest and digital banking grows fast. We also interviewed bank employees to gain complementary perspectives of these help givers. Our findings show that older adults used both physical and digital platforms as an ecosystem based on perceived pros and cons. Perceived usefulness, self-confidence, and social influence were key motivators for learning digital banking.They experienced app-related (e.g., insufficient error-recovery support) and user-related challenges (e.g., trust, security and privacy concerns, low perceived self-efficacy) and developed coping strategies. We discuss design considerations to improve their banking experiences.CCS Concepts: • Human-centered computing → Accessibility; • Social and professional topics → Seniors.

“…Le et al [37] further discovered that multiple visual cues in health visualizations could impair older adults' information processing, with participants using a combination of prior knowledge and visualization elements when interacting with visual displays. Fan et al [23] identified challenges for older adults in understanding interactive COVID-19 data visualizations, such as insufficient information clarity. Additionally, Cajamarca et al [14] observed that older Chilean adults interpreted health data on smartwatches more accurately without progress indicators, which otherwise distracted them from essential information.…”

“…As individuals age, they undergo gradual changes in perception, cognition, and physical abilities that can impact their capacity to use visualizations effectively. For example, a recent survey by Fan et al [23] found that older adults struggled to effectively use and gain insights from COVID-19 visualizations due to factors such as indistinguishable colors for aging vision (e. g., blue-green), low contrast ratios between graphical elements, and small font sizes. The onset and progression of age-related changes can vary greatly among individuals due to genetics, lifestyle, and overall health.…”

W E detail and illustrate glanceability as a crucial requirement for several types of mobile visualizations. For example, in a difficult terrain, a runner can only check a smartwatch for elevation or heart rate data for a few hundred milliseconds before the eyes need to refocus on the trail ahead. Such quick information needs differ from those in traditional visualizations that are meant for deep analysis and interaction with possibly large and complex datasets. Visualizations designed for quick information needs are described under a variety of terms in the literature such as glanceable visualizations, glanceable displays, peripheral displays, ambient visualizations, or sometimes as forms of casual visualizations. To clarify how glanceability is used in the field of Visualization, we discuss these related terms with respect to visualization concepts, drawing from not only Visualization but also, Vision Sciences, Human-Computer Interaction, and Ubiquitous Computing, revealing how the use of the term glanceable differs in these communities. Drawing from these different perspectives, we discuss specific values for glanceable mobile visualizations: presence & accessibility, simplicity & understandability, as well as suitability & purposefulness. Based on these values, we explore different evaluation methodologies, ranging from lab studies, to online experiments, to evaluation in the field and conclude with a discussion of open challenges in the design of future glanceable mobile visualizations.
