Abstract
This document describes a waterproof wearable computing device (e.g., smart watch, smart ring, hearable device, or other body-mounted devices or sensors) that aids in aquatic safety by collecting environmental, biometric, and kinematic data from the user and preemptively alerting the user of a hypoxia induced event (e.g., drowning, unconsciousness, etc.). The wearable computing device uses a multi-sensor fusion approach integrating device components such as barometers, accelerometers, gyroscopes, and physiological sensors to obtain depth data, underwater duration data, kinematic movement data, biometric data, and environmental data, which may be combined with a historical user baseline to determine a lethargy score. The wearable computing device may compare the lethargy score to a threshold and based on the comparison the wearable computing device may provide an alert (e.g., ascend, air, breathe, hypoxia, etc.) to the user before the onset of a hypoxia induced event (e.g., shallow water blackout (SWB), syncope, loss of consciousness, swallowing water, etc.). The alert may be designed for aquatic environments, such that the alert may account for wetsuits, goggles, masks, etc.
