Wearable Machine Interface System for Tracking and Controlling Mental Stress Using Weist-Worn Wearable Devices
Wrist-worn wearable devices provide rich sets of pulsatile physiological data under various modalities and circumstances. An unexploited capability is that the pulsatile physiological time series collected by wrist-worn wearable devices can be used for recovering internal brain dynamics. Inferring the underlying neural mechanisms and reconstruction of the mental-stress-related brain dynamics could potentially be accomplished entirely through wrist-worn wearable devices. The method is validated by analyzing electrodermal activity (EDA) pulsatile data in the context of mental-stress-related arousal, and can be extended to other pulsatile physiological signals (e.g. cortisol, heartbeat data). The outcomes will be (1) a portfolio of wrist-worn wearable-device-based brain decoders that can be optimized to exploit the constraints of a given clinical application and wrist-worn wearable device data collection capabilities; (2) a toolbox of bio-inspired controllers that can have inhibitory and excitatory effects for maintaining a neural state within a desired range.
