Abstract:
1. A method for informing a user of an intoxication state over time, comprising: upon receiving an input provided by the user at a user interface of a wrist-borne mobile computing device, prompting the user to provide a breath sample to a sample receiving module in communication with the wrist-borne mobile computing device, at a first time point; at a processing subsystem in communication with the wrist-borne mobile computing device, receiving a breath sample signal derived from the breath sample; at the processing subsystem, determining a value of a blood alcohol content (BAC) metric from the breath sample signal; at the processing subsystem, generating a predicted temporal profile of the blood alcohol content metric for the user over time, including an estimated time point at which the user will reach a state of sobriety, based upon the value of the blood alcohol content metric and the first time point; and transmitting commands, from the processing subsystem to the wrist-borne mobile computing device, that prompt the wrist-borne mobile computing device to display information from an analysis derived from the predicted temporal profile and informative of the estimated time point at the user interface, thus informing the user of the intoxication state over time.
