TL;DR
This paper introduces MyMove, a speech-based smartwatch app designed to help older adults easily label their activities in real-time, addressing the gap in activity tracking data for this demographic.
Contribution
We developed and evaluated a novel speech-based app enabling older adults to collect in-situ activity labels with low effort, demonstrating high engagement and valuable data collection.
Findings
Participants captured 1,224 verbal activity reports
Collected 1,885 activity labels with effort level and timespan
High engagement in real-world deployment
Abstract
Current activity tracking technologies are largely trained on younger adults' data, which can lead to solutions that are not well-suited for older adults. To build activity trackers for older adults, it is crucial to collect training data with them. To this end, we examine the feasibility and challenges with older adults in collecting activity labels by leveraging speech. Specifically, we built MyMove, a speech-based smartwatch app to facilitate the in-situ labeling with a low capture burden. We conducted a 7-day deployment study, where 13 older adults collected their activity labels and smartwatch sensor data, while wearing a thigh-worn activity monitor. Participants were highly engaged, capturing 1,224 verbal reports in total. We extracted 1,885 activities with corresponding effort level and timespan, and examined the usefulness of these reports as activity labels. We discuss the…
