Toward a Unified Metadata Schema for Ecological Momentary Assessment with Voice-First Virtual Assistants
Chen Chen, Khalil Mrini, Kemeberly Charles +5
Ecological momentary assessment (EMA) is used to evaluate subjects' behaviors and moods in their natural environments, yet collecting real-time and self-report data with EMA is cha…
How do Older Adults Set Up Voice Assistants? Lessons Learned from a Deployment Experience for Older Adults to Set Up Standalone Voice Assistants
Chen Chen, Ella T. Lifset, Yichen Han +5
While standalone Voice Assistants (VAs) are promising to support older adults' daily routine and wellbeing management, onboarding and setting up these devices can be challenging. A…
Screen or No Screen? Lessons Learnt from a Real-World Deployment Study of Using Voice Assistants With and Without Touchscreen for Older Adults
Chen Chen, Ella T. Lifset, Yichen Han +5
While voice user interfaces offer increased accessibility due to hands-free and eyes-free interactions, older adults often have challenges such as constructing structured requests…
VRContour: Bringing Contour Delineations of Medical Structures Into Virtual Reality
Chen Chen, Matin Yarmand, Varun Singh +4
Contouring is an indispensable step in Radiotherapy (RT) treatment planning. However, today's contouring software is constrained to only work with a 2D display, which is less intui…
A DirectX-Based DICOM Viewer for Multi-User Surgical Planning in Augmented Reality
Menghe Zhang, Weichen Liu, Nadir Weibel +1
Preoperative medical imaging is an essential part of surgical planning. The data from medical imaging devices, such as CT and MRI scanners, consist of stacks of 2D images in DICOM…
Investigating Input Modality and Task Geometry on Precision-first 3D Drawing in Virtual Reality
Chen Chen, Matin Yarmand, Zhuoqun Xu +3
Accurately drawing non-planar 3D curves in immersive Virtual Reality (VR) is indispensable for many precise 3D tasks. However, due to lack of physical support, limited depth percep…
Towards Visualization of Time-Series Ecological Momentary Assessment (EMA) Data on Standalone Voice-First Virtual Assistants
Yichen Han, Christopher Bo Han, Chen Chen +5
Population aging is an increasingly important consideration for health care in the 21th century, and continuing to have access and interact with digital health information is a key…
QTBIPOC PD: Exploring the Intersections of Race, Gender, and Sexual Orientation in Participatory Design
Naba Rizvi, Reggie Casanova-Perez, Harshini Ramaswamy +3
As Human-Computer Interaction (HCI) research aims to be inclusive and representative of many marginalized identities, there is still a lack of available literature and research on…
Making Hidden Bias Visible: Designing a Feedback Ecosystem for Primary Care Providers
Naba Rizvi, Harshini Ramaswamy, Reggie Casanova-Perez +2
Implicit bias may perpetuate healthcare disparities for marginalized patient populations. Such bias is expressed in communication between patients and their providers. We design an…
Understanding Barriers and Design Opportunities to Improve Healthcare and QOL for Older Adults through Voice Assistants
Chen Chen, Janet G. Johnson, Kemeberly Charles +6
Voice based Intelligent Virtual Assistants (IVAs) promise to improve healthcare management and Quality of Life (QOL) by introducing the paradigm of hands free and eye free interact…
Interactive Multi-User 3D Visual Analytics in Augmented Reality
Wanze Xie, Yining Liang, Janet Johnson +6
This publication reports on a research project in which we set out to explore the advantages and disadvantages augmented reality (AR) technology has for visual data analytics. We d…
Managing Commercial HVAC Systems: What do Building Operators Really Need?
Bharathan Balaji, Nadir Weibel, Yuvraj Agarwal
Buildings form an essential part of modern life; people spend a significant amount of their time in them, and they consume large amounts of energy. A variety of systems provide ser…
Genie: A Longitudinal Study Comparing Physical and Software-augmented Thermostats in Office Buildings
Bharathan Balaji, Jason Koh, Nadir Weibel +1
Thermostats are primary interfaces for occupants of office buildings to express their comfort preferences. However, standard thermostats are often ineffective due to inaccessibilit…
