Screen or No Screen? Lessons Learnt from a Real-World Deployment Study of Using Voice Assistants With and Without Touchscreen for Older Adults

ASSETS 202335‑day deployment shows screens aid comprehension but speech stays dominant for older adults.

How do Older Adults Set Up Voice Assistants? Lessons Learned from a Deployment Experience for Older Adults to Set Up Standalone Voice Assistants

DIS 2023Diary study uncovers setup hurdles with voice assistants and suggests UI tweaks.

Towards Visualization of Time–Series Ecological Momentary Assessment (EMA) Data on Standalone Voice–First Virtual Assistants

ASSETS 2022 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

Toward a Unified Metadata Schema for Ecological Momentary Assessment with Voice-First Virtual Assistants

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.

How might an intelligent voice assistant address older adults' health-related needs?

J Am Geriatr Soc 2021Brief (2–4 h) workshops boosted clinicians’ self-rated comfort and understanding of decision-making-capacity assessments, with post-session gains in 50–90 % of participants (p

Understanding Barriers and Design Opportunities to Improve Healthcare and QOL for Older Adults through Voice Assistants

ASSETS 2021In 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
