Background
Emergency departments (EDs) are high-pressure environments where clinicians diagnose patients under significant constraints, including limited medical histories, severe time pressures, and frequent interruptions. Current ED care practices often inadequately support meaningful patient participation. Most interventions prioritize clinical...
BACKGROUND
In the Emergency Department (ED), healthcare providers face extraordinary pressures in delivering accurate diagnoses and care, often working with fragmented or inaccessible patient histories while managing severe time constraints and constant interruptions. These challenges and pressures may lead to potential errors in the ED diagnostic...
BACKGROUND
Emergency departments (EDs) are high-pressure environments where a diagnosis is made in a resource-constrained context. These environments also require complicated interactions between patients, caregivers, and healthcare providers to make timely diagnoses. EDs, in consequence, predispose to suboptimal diagnostic outcomes, leading to pot...
BACKGROUND
Hypertension (HTN) is one of the most important cardiovascular disease risk factors and affects over 100 million American adults. HTN-related health inequities are abundant in Black communities as Blacks are more likely to utilize the emergency department (ED) for chronic disease-related ambulatory care, which is strongly linked to lower...

Previous works have shown that effective communication between parental caregivers and child patients has many benefits to the children, such as providing emotional support and coping skills for health management. Drawing on semi-structured interviews, we have identified the challenges parental caregivers face when communicating with their children...
In-situ self-reporting is an important measurement method used for capturing daily experience data right-in-the-moment in dynamic contexts. Research has been conducted to reduce the demand placed on users for manually reporting data in context. In this regard, smartwatches offer inherent benefits for making self-reporting more convenient and facili...
Objective
Family caregiving is an important public health issue, particularly with the aging population. In recent years, mobile health (mHealth) technology has emerged as a potential low-cost, scalable platform to address caregiver support needs, and thereby alleviate the burden on caregivers. This study sought to examine the support needs of fami...
African Americans have faced health disparities in terms of access to health care and treatment of illnesses. The novel coronavirus disease 2019 (COVID-19) pandemic exacerbates those disparities caused by limited access to medical care and healthy lifestyles, vulnerability to misleading information, and mistrust of the medical profession, all of wh...
In this paper, we present a preliminary analysis of past review studies on conversational agents (CAs) in health care in terms of user acceptance. We show a trend of user acceptance in CAs in health care by synthesizing the outcomes of different works regarding five main factors (i.e. satisfaction, ease of use, usefulness, the number of interaction...
Conversational agents have increasingly been deployed in healthcare applications. However, significant challenges remain in developing this technology. Recent research in this area has highlighted that: i) patient safety was rarely evaluated; ii) health outcomes were poorly measured, and iii) no standardised evaluation methods were employed. The co...

In this paper, we report findings from our pilot study using semi-structured interviews to assess users' perceived receptivity to an adaptive system of engagement strategies, ewrapper, that "wraps" around decision points in a dietary self-monitoring mobile application. Study participants were asked to perform a "think-aloud" usability exercise with...
In pediatric chronic care, the treatment process affects not just the child's physical health, but his or her psychosocial and emotional development. As a result, caring for pediatric patients with a chronic illness such as cancer is becoming a daunting task for parental caregivers. They are expected to fulfill the caregiving needs of managing the...
This paper is a literature review of 57 papers that have examined the role and impact of conversational agents (CAs) in the health domain. We note that three key themes repeatedly arose during the review: therapeutic alliance, trust, and human intervention. We also point out several areas that have been largely overlooked, such as specific patient...

In-situ self-reporting is a widely-used data collection method which offers many benefits in the clinical, psychological and social research fields. However, high capture burden issues have surfaced as in-situ self-reporting expands and diversifies in various studies. Thus, we draw attention to the design space of low-burden in-situ self-reporting....
Dealing with a chronic condition often involves daunting tasks and the participation of multiple people in care. Previous literature has documented collaboration between patients, clinicians, close relatives, friends, and paid carers. However, collaboration in care has been mostly examined as the work of dyads, such as patients and clinicians. In t...
Physical play opportunities for people with motor disabilities typically do not include co-located play with peers without disabilities in traditional sport settings. In this paper, we present a prototype of a wheelchair-accessible interactive floor projection system, iGYM, designed to enable people with motor disabilities to compete on par with, a...
Real-time collaboration between a requester and crowd workers expands the scope of tasks that crowdsourcing can be used for by letting requesters and crowd workers interactively create various artifacts (e.g., a sketch prototype, writing, or program code). In such systems, it is increasingly common to allow requesters to verbally describe their req...
Mental health wellness concerns are a significant issue among emerging adults due to the compounded stressors of life changes, new responsibilities, and career-related burdens. Due to a lack of support and the stigma associated with seeking help, they often do not receive adequate professional care. In this paper, we show how emerging adults seek h...
Although the ability of patients to access their health information during ongoing care is considered crucial for better health outcomes and increased satisfaction, the current care model places patients in a passive role. To investigate the patient experience in the hospital environment where information is lacking and in accessible, we conducted...
Patient-provider communication is crucial to the quality of patient care. To avoid communication breakdowns, existing studies often aim to improve patients' health literacy or providers' interpersonal communication skills. Little has been done to look at the interaction between the two parties or the situated health practices where the communicatio...
People are increasingly involved in the self-management of their own health, including chronic conditions. With technology advances, the choice of self-management practices, tools, and technologies has never been greater. The studies reported here investigated the information seeking practices of two different chronic health populations in their qu...
In this paper, we propose a single-drone-based localization for radio frequency (RF) sources in an outdoor environment. For fast and accurate localization, we propose a dynamic trajectory planning scheme, which guides the RF scanning drone toward a direction minimizing the geometric dilution of precision (GDOP) in order to minimize the uncertainty...
This study investigates how people manage chronic migraine -- an illness characterized by unpredictable, intermittent breakouts in everyday life. Participants in our study must self-identify migraine symptoms, triggers, and effective coping mechanisms while also seeking social recognition and assistance from a social network during migraine attacks...
Implementation of large Health Information Technology (HIT) systems is critical to healthcare organizations and has seen heavy investment. However, research has not fully explored the adaptation of HIT systems, particularly the tensions between individual flexibility and organizational needs in the adaptation process. This study analyzes how Emerge...
Patient-provider collaboration is considered crucial to successful patient care. However, while many CSCW and health informatics studies have focused on collaborative care incorporating patient awareness in chronic care management, very little attention has been given to emergency care. I am conducting a qualitative study of patient care trajectori...
In this paper, we describe a practice that is common across multiple heterogeneous contexts but enacted differently depending on the unique constellation of resources and demands present in each local context. Using the case of informal documentation practices in two departments of a single hospital, Emergency and Labor & Delivery, we describe how...
Health and wellness have drawn significant attention in the HCI and CSCW communities. Many prior studies have focused on designing technologies that are patient-centric, allowing caregivers to take better care of patients. Less has been done in understanding and minimizing the burden of caregiving in caregivers' own lives. We conducted a qualitativ...
We conducted an observational study in an Emergency Department (ED) to examine the adaptation process after deploying an Electronic Medical Records (EMR) system. We investigated how EMR was adapted to the complex clinical work environment and how doctors and nurses engaged in the adaptation process. In this paper, we present three cases in which ED...
There has been a growing interest in the HCI community to study Health, with particular focus in understanding healthcare practices and designing technologies to support and to enhance these practices. A majority of current health studies in HCI have focused on either clinical settings, such as hospitals and clinics, or non-clinical spaces, like pa...
We conducted an observational study to investigate nurses' communication behaviors in an Emergency Department (ED). Our observations reveal unique collaboration practices exercised by ED staff, which we term as "loosely formed team collaboration." Specifically, ED patient care teams are dynamically and quickly assembled upon patient arrival, wherei...
The goal of this study was to examine the effects of medical notes (MD) in an electronic medical records (EMR) system on doctors' work practices at an Emergency Department (ED).
We conducted a six-month qualitative study, including in situ field observations and semi-structured interviews, in an ED affiliated with a large teaching hospital during t...
Previous studies suggest that mobile phones could prevent many communication and information breakdowns that commonly occur in a hospital environment. However, the actual benefits of mobile phones in medical work remain unexplored. We studied mobile phone usage among nurses in an Emergency Department (ED). Surprisingly, mobile phones were not favor...
Upon leaving the hospital, parents of high-risk infants experience a variety of challenges in providing care at home. In this work, we present results from a qualitative study to understand the role of social interaction and information-sharing surrounding high-risk infants among both home caregivers and health professionals. These results demonstr...
We propose that citizen science methods can engage riders with disabilities and others in improving public transportation accessibility by documenting and assessing problems and good solutions throughout the system. This will empower riders, resulting in a greater understanding of the transportation system, and improve the feedback loop between rid...
As long as people have traveled, they have constructed bags to help them carry more items than their hands will hold. While quite effective at keeping things together, bags do a poor job of communicating when something is missing. We propose that there exists an opportunity for the HCI community to improve the quality of people's lives by creating...
Designers are skilled at sketching and prototyping the look of interfaces, but to explore various behaviors (what the interface does in response to input) typically requires programming using Javascript, ActionScript for Flash, or other languages. In our survey of 259 designers, 86% reported that the behavior is more difficult to prototype than the...
While a designer's focus used to be the design of non-interactive elements such as graphics or anima- tions, today's designers deal with various levels of interactivity such as mouse, keyboard and touch screen interaction. Unfortunately, it is challenging for design- ers to create these diverse interactions since most im- plementation tools such as...
The "Natural Programming" project at Carnegie Mellon University has been working for more than 10 years to make programming more "natural", or closer to the way people think. We have addressed the needs of all kinds of programmers: novices, professionals and end-user programmers. Many studies were performed which provided new insights and led to ne...
Parents always desire to take good care of their children and manage their numerous responsibilities. One of parents' main responsibilities is to manage their children's health. Through their actions of caring for their children, parents want to know they're doing the best job to ensure their children's well being. Unfortunately, much of the time t...
