When living apart, grandparents and grandchildren often use audio-visual communication approaches to stay connected. However, these seldom provide sufficient companionship intimacy due a lack of co-presence spatial interaction, which can be fulfilled by immersive virtual reality (VR). To understand how might leverage VR facilitate their remote better inform future design, we conducted user-centered participatory design study with twelve pairs grandchildren. Results show that affords casual...

AI is promising in assisting UX evaluators with analyzing usability tests, but its judgments are typically presented as non-interactive visualizations. Evaluators may have questions about test recordings, no way of asking them. Interactive conversational assistants provide a Q&A dynamic that improve analysis efficiency and evaluator autonomy. To understand the full range analysis-related questions, we conducted Wizard-of-Oz design probe study 20 participants who interacted simulated via text...

People who are blind or have low vision (BLV) encounter numerous challenges in their daily lives and work. To support them, various haptic assistive tools been developed. Despite these advancements, the effective utilization of tools—including optimal feedback on-body stimulation positions for different tasks along with limitations—remains poorly understood. Recognizing gaps, we conducted a systematic literature review spanning two decades (2004-2024) to evaluate development within HCI...

Usability testing is vital for enhancing the user experience (UX) of interactive systems. However, analyzing test videos complex and resource-intensive. Recent AI advancements have spurred exploration into human-AI collaboration UX analysis, particularly through natural language. Unlike user-initiated dialogue, our study investigated potential proactive conversational assistants to aid evaluators automatic suggestions at three distinct times: before, in sync with, after usability problems....

The global aging trend compels older adults to navigate the evolving digital landscape, presenting a substantial challenge in mastering smartphone applications. While Augmented Reality (AR) holds promise for enhancing learning and user experience, its role aiding adults' app exploration remains insufficiently explored. Therefore, we conducted two-phase study: (1) workshop with 18 identify challenges potential AR interventions, (2) tech-probe participatory design sessions 15 participants...

Incorporating accessibility education into undergraduate computer science (CS) programs is essential for preparing future technology professionals to create inclusive technology. However, many CS lack coverage, often confining it human-computer interaction (HCI) courses. To address this gap, we developed assignments seamlessly integrated core We collaborated closely with ten instructors select and customize these suit their needs. evaluate the impact of assignments, conducted interviews...

Charts are crucial in conveying information across various fields but inaccessible to blind and low vision (BLV) people without assistive technology. Chart comprehension tools leveraging haptic feedback have been used widely often bulky, expensive, static, rendering them inefficient for chart data. To increase device portability, enable multitasking, provide efficient assistance comprehension, we introduce a novel system that delivers unobtrusive modulated electrotactile directly the...

AI has been increasingly adopted in user experience (UX) analysis, which UX evaluators review test recordings to identify usability problems. However, most AI-infused systems apply fully automatic approaches, leading distrust from evaluators. In my dissertation work, we consider as assisting, not replacing human judgment. Through an international survey, investigated the current practices and challenges of identified opportunity for assistance. We then studied nuanced cooperative work...

The banking industry has been integrating digital technologies globally. However, accepting new is challenging in particular for older adults. We focus on adults' experiences China, where transactions have growing rapidly, to provide a perspective how they adapt this trend. conducted an online survey with 155 adults who are 60 or above (M = 70, SD 9) from 18 provinces explore their practices and challenges. Our results show that conduct frequently. few do so using platforms despite long wait...

Analysis is a key part of usability testing where UX practitioners seek to identify problems and generate redesign suggestions. Although previous research reported how analysis was conducted, the findings were typically focused on individual or based small number professionals in specific geographic regions. We conducted an online international survey 279 their practices challenges while collaborating during data analysis. found that often under time pressure conduct adopted three modes...

Being able to analyze and derive insights from data, which we call Daily Data Analysis (DDA), is an increasingly important skill in everyday life. While the accessibility community has explored ways make data more accessible blind low-vision (BLV) people, little known about how BLV people perform DDA. Knowing people's strategies challenges DDA would allow them. Toward this goal, conducted a mixed-methods study of interviews think-aloud sessions with (N=16). Our revealed five key approaches...

This paper describes an ongoing multi-scale visual analytics approach for exploring and analyzing biomedical knowledge at scale. We utilize global local views, hierarchical flow-based graph layouts, multi-faceted search, neighborhood recommendations, document visualizations to help researchers interactively explore, query, analyze biological graphs against the backdrop of knowledge. The generality our - insofar as it requires only linked documents means can support a range therapeutic use...

Literacy—the ability to read, write, and comprehend text—is an important topic addressed by UNESCO. Despite global efforts promote adult literacy education, rural areas with limited resources still lag behind. As livestreaming has gained popularity in China, many streamers leveraged its accessibility affordability reach low-literate adults. To gain a better understanding of the practices challenges faced education through livestreaming, we conducted mixed-methods study involving 7-day...

Inter-generational communication is essential for bridging generational gaps and fostering mutual understanding. However, maintaining it complex due to cultural, communicative, geographical differences. Recent research indicated that while Virtual Reality (VR) creates a relaxed atmosphere promotes companionship, inadequately addresses the complexities of inter-generational dialogue, including variations in values relational dynamics. To address this gap, we explored opportunities Artificial...

We present a compact, field-portable lens-free microscope basedon the principle of spatio-spectral light-field fusion. This is firsttime device this kind has been introduced whereby both superresolutionand signal-to-noise ratio are enhanced via marriageof synthetic aperture imaging and spectral fusionholography, culminating in system that self-contained fieldportablewhile achieving high resolution, contrast, strong signal fidelity,and ultra-wide field-of-view.

Older adults increasingly adopt small-screen devices, but limited motor dexterity hinders their ability to type effectively. While a 9-key (T9) keyboard allocates larger space each key, it is shared by multiple consecutive letters. Consequently, users must interrupt gestures when typing letters, leading inefficiencies and poor user experience. Thus, we proposed novel that leverages the currently unused key 1 duplicate letters from previous allowing entry of without interruptions. A study...

Reviewing a think-aloud video is both time-consuming and demanding as it requires UX (user experience) professionals to attend many behavioral signals of the user in video. Moreover, challenges arise when multiple need collaborate reduce bias errors. We propose collaborative visual analytics tool, CoUX, facilitate evaluators collectively reviewing usability test videos digital interfaces. CoUX seamlessly supports problem identification, annotation, discussion an integrated environment. To...
