Abstract

A computer-implemented method of detecting physiological attributes of a wearer of a computerized wearable device having one or more sensors comprises (1) using the information from the one or more sensors to assess the physiology of the wearer; and (2) notifying the wearer of the wearer'"'"'s physiology. In various embodiments, the method involves using the wearable device to determine the wearer'"'"'s current posture, balance, alertness, and/or physical state and comparing the current posture, balance, alertness and/or physical state to at least one baseline measurement. For example, the system may measure a baseline posture to determine when the wearer'"'"'s current posture deviates from the baseline posture, and notify the wearer so that the wearer may improve his or her posture. In other embodiments, the computerized wearable device may detect one or more of the wearer'"'"'s physiological characteristics (e.g., oxygen levels, pulse rate, pupil size, etc.) and determine the wearer'"'"'s alertness level.
