  The general public and medical professionals recognized the importance of
accurately measuring and storing blood oxygen levels and heart rate during the
COVID-19 pandemic. The demand for accurate contact-less devices was motivated
by the need for cross-infection reduction and the shortage of conventional
oximeters, partially due to the global supply chain issue. This paper evaluated
a contact-less mini-program HealthyPai's heart rate (HR) and oxygen saturation
(SpO2) measurements compared with other wearable devices. In the HR study of
185 samples (81 in the laboratory environment, 104 in the real-life
environment), the mean absolute error (MAE) $\pm$ standard deviation was
$1.4827 \pm 1.7452$ in the lab, $6.9231 \pm 5.6426$ in the real-life setting.
In the SpO2 study of 24 samples, the mean absolute error (MAE) $\pm$ standard
deviation of the measurement was $1.0375 \pm 0.7745$. Our results validated
that HealthyPai utilizing the Integrated Image Deep Learning Solution (IIDLS)
framework can accurately measure HR and SpO2, providing the test quality at
least comparable to other FDA-approved wearable devices in the market and
surpassing the consumer-grade and research-grade wearable standards.
