Reliability Assessment of New and Updated Consumer-Grade Activity and Heart Rate Monitors

Abstract

The aim of this paper is to address the need for reliability assessments of new and updated consumer-grade activity and heart rate monitoring devices. This issue is central to the use of these sensor devices and it is particularly important in their medical and assisted living application.\nUsing an example lightweight empirical approach, experimental results for heart rate acquisitions from Garmin VivoSmart 3 (v4.10) smartwatch monitors are presented and analyzed. The reliability issues of optically-acquired heart rates, especially during periods of activity, are demonstrated and discussed. In conclusion, the paper recommends the empirical assessment of new and updated activity monitors, the sharing of this data and the use of version information across the literature.
