Query: MobilePhys: Personalized Mobile Camera-Based Contactless Physiological
  Sensing   Camera-based contactless photoplethysmography refers to a set of popular
techniques for contactless physiological measurement. The current
state-of-the-art neural models are typically trained in a supervised manner
using videos accompanied by gold standard physiological measurements. However,
they often generalize poorly out-of-domain examples (i.e., videos that are
unlike those in the training set). Personalizing models can help improve model
generalizability, but many personalization techniques still require some gold
standard data. To help alleviate this dependency, in this paper, we present a
novel mobile sensing system called MobilePhys, the first mobile personalized
remote physiological sensing system, that leverages both front and rear cameras
on a smartphone to generate high-quality self-supervised labels for training
personalized contactless camera-based PPG models. To evaluate the robustness of
MobilePhys, we conducted a user study with 39 participants who completed a set
of tasks under different mobile devices, lighting conditions/intensities,
motion tasks, and skin types. Our results show that MobilePhys significantly
outperforms the state-of-the-art on-device supervised training and few-shot
adaptation methods. Through extensive user studies, we further examine how does
MobilePhys perform in complex real-world settings. We envision that calibrated
or personalized camera-based contactless PPG models generated from our proposed
dual-camera mobile sensing system will open the door for numerous future
applications such as smart mirrors, fitness and mobile health applications.
