Key result
The VitaMon mobile sensing system measured inter-heartbeat intervals from facial video with an average error of 14.26 ms (personal model) and 21.65 ms (general model).
Why the study?
Can the VitaMon mobile sensing system accurately measure inter-heartbeat interval and heart rate variability from facial video?
Observational (n=30)
Can the VitaMon mobile sensing system accurately measure inter-heartbeat interval and heart rate variability from facial video?
A smartphone camera-based system using deep neural networks can accurately estimate inter-heartbeat intervals and heart rate variability from facial video.

May enable remote HRV monitoring via smartphone; leaves open clinical validation in larger, diverse cohorts.
Huynh et al. (2019) reported an observational. VitaMon mobile sensing system vs. Reference signal was evaluated on Inter-heartbeat interval (IBI) measurement error. The VitaMon mobile sensing system measured inter-heartbeat intervals from facial video with an average error of 14.26 ms (personal model) and 21.65 ms (general model).
