Detection and response to arousal activations

A wrist-worn wearable computing device, comprising:

• a display screen;
• a plurality of sensors, the plurality of sensors comprising at least one first electrode on a bottom face of the wrist-worn wearable computing device and contacting a wrist of the user and at least one second electrode on a top surface of the wrist-worn wearable computing device, the at least one first and second electrodes being electrically isolated within the wrist-worn wearable computing device;
• at least one processor;
• and
• memory including instructions that, when executed by the at least one processor, cause the at least one processor to:
• receive, from the plurality of sensors on the wrist-worn wearable computing device, data indicative of an arousal event associated with a sympathetic nervous system, wherein the data indicative of the arousal event associated with the sympathetic nervous system comprises, at least, electrodermal activity (EDA) data captured when the user places one or more fingers on the at least one second electrode on the top surface of the wrist-worn wearable computing device, the at least one second electrode comprising at least one EDA sensor that measures, at least, a skin conductance response to sweat or moisture on the skin of the user;
• classify the data indicative of the arousal event associated with the sympathetic nervous system into a plurality of bins, the plurality of bins corresponding to periods of time;
• determine at least one bin of the plurality of bins exceeds a threshold;
• and
• in response to the at least one bin exceeding the threshold, provide, via the display screen, a notification to a user identifying the arousal event associated with the sympathetic nervous system.

A non-transitory computer-readable storage medium comprising instructions that, when executed by at least one processor, cause the at least one processor to:

• receive, from a plurality of sensors on a wrist-worn wearable computing device, data indicative of an arousal event associated with a sympathetic nervous system, the plurality of sensors comprising at least one first electrode on a bottom face of the wrist-worn wearable computing device and contacting a wrist of the user and at least one second electrode on a top surface of the wrist-worn wearable computing device, the at least one first and second electrodes being electrically isolated within the wrist-worn wearable computing device, wherein the data indicative of the arousal event associated with the sympathetic nervous system comprises, at least, electrodermal activity (EDA) data captured when the user places one or more fingers on the at least one second electrode on the top surface of the wrist-worn wearable computing device, the at least one second electrode comprising at least one EDA sensor that measures, at least, a skin conductance response to sweat or moisture on the skin of the user;
• classify the data indicative of the arousal event associated with the sympathetic nervous system into a plurality of bins, the plurality of bins corresponding to periods of time;
• determine at least one bin of the plurality of bins exceeds a threshold;
• and
• in response to the at least one bin exceeding the threshold, provide, via the display screen, a notification to a user identifying the arousal event associated with the sympathetic nervous system.
