Paper instructions are a mainstream medium for sharing knowledge. However, consuming such instructions and translating them into activities can be inefficient due to the lack of connectivity with the physical environment. PaperToPlace is a novel workflow comprising an authoring pipeline, which allows the authors to rapidly transform and spatialize existing paper instructions into an MR experience, and a consumption pipeline, which computationally places each instruction step at an optimal location that is easy to read and does not occlude key interaction areas. This is a collaborative project with Adobe Research.

Assessing accessibility for wheelchair users can be challenging, due to lack of accessibility details needed for individual users. Embodied Exploration is a VR technique to deliver the experience of a physical visit while keeping the convenience of remote assessment. Embodied Exploration allows wheelchair users to explore high-fidelity digital replicas of physical environments with themselves embodied by avatars, leveraging the increasingly affordable VR headsets.

To explore the potential opportunities for visualizing time-series based EMA data on standalone IVAs, we designed a prototype system, where older adults are able to query and examine the time–series EMA data on Amazon Echo Show — a widely used commercially available standalone screen–based IVA

EICS 2022
We present an exploratory study that uses iterative design to understand needs and opportunities to bring contour delineation into an immersive 3D space, such as the one enabled by today’s head-mounted VR displays

Trials 2022
The Social Mobile Approaches to Reducing Weight (SMART) 2.0 Study is a 24-month parallel-group randomized controlled trial that will include 642 overweight or obese participants, aged 18–35 years, from universities and community colleges in San Diego, CA.

ASTRO 2022
Daily re-evaluation of contours associated with adaptive planning is time-intensive and difficult to access. This project evaluated the efficacy of everyday touch devices for contouring using a novel cross-platform interface.

CUI 2021
We designed a novel unified metadata schema to enable Human-Computer Interaction (HCI), user experience (UX), and behavioral health researchers to rapidly prototype Ecological Momentary Assessment (EMA) data collection applications on different voice-first smart devices with built-in IVAs.

CHI 2022 - QT-BIPOC PD Workshop
We present wireframes displaying communication metrics that negatively impact patient-centered care divided into the following categories: digital nudge, dashboard, and guided reflection. Our wireframes provide quantitative, real-time, and conversational feedback promoting provider reflection on their interactions with patients.

CHI 2022
To understand the perspectives of clinicians on the design of effective educational strategies and for tools to help identify implicit bias, we conducted 21 semi-structured interviews with primary care clinicians about their perspectives and design recommendations for tools to improve patient-centered communication and to help mitigate implicit bias.

CHI 2021
In this paper, we describe ARTEMIS' design process with a summary of specific user goals ARTEMIS addresses. We also describe the system implementation and show an early validation of how the system addresses user goals.

CHI 2021
This paper investigates in-class interactions in synchronous online classrooms when the choice of modality is discretionary, such that students choose when and if they turn on their cameras and microphones

ASSETS 2021
In this paper we focus on the processes of care delivery and QOL enhancements for older adults as a collaborative task between patients and providers. By interviewing 16 older adults living independently or semi–independently and 5 providers, we identified 12 barriers that older adults might encounter during daily routine and while managing health

As the elderly population and associated number of persons with dementia increase, so does the need for decision-making capacity assessments (DMCAs). Many healthcare professionals (HCPs), however, do not feel prepared to conduct DMCAs. We have provided 4-h DMCA workshops to HCPs since 2006 and offered physicians either a 3-h or 2-day DMCA workshop from 2013 to present. We evaluated the effectiveness of the workshops on self-reported key concepts of capacit

CHI 2021
Co-location matters, especially when running collaborative design thinking workshops. What if participation cannot occur in person? How can we conduct these workshops remotely?

CHI 2021
This paper presents a 2x2 mixed factorial experiment that explores the effects of providing spatial information and system-generated guidance to task objects. It also investigates the effects of such guidance on the remote collaborators need for spatial information.

Hidden biases in patient-provider interactions can result in poor communication in clinical interactions and healthcare disparities. The UnBIASED Research Project is combining stakeholder engagement with computational sensing to automatically detect hidden biases and provide automated feedback on communication quality during clinical encounters. Early insights from stakeholder engagement highlight the importance of nonverbal communication as social signals of hidden bias.
