Abstract: Measuring the heart rate from a convenient location such as the wrist is commonly achieved using photoplethysmography. As a consequence, this method is widely used on commercial wearable devices. Unfortunately, it also highly suffers from motion artefacts superimposed into the cardiac frequency band which generally lead to incorrect heart rate estimation. In this paper we propose a new approach that uses the ambient light contribution as a reference for motion artefacts reduction. Contrarily to accelerometer-based techniques, the proposed method does not require any additional hardware. Moreover, it is especially efficient for reduction of micro-motions that can’t be addressed using conventionally used accelerometry. Using the ambient light signal as a reference in association with adaptive filtering has demonstrated promising results for the reduction of artefacts during both periodic and random motion events.
