A system, method, and device for monitoring a physiological characteristic and/or response of a user includes a wearable monitoring device for displaying a status level of a physiological characteristic and/or response. When attached to or against the user's body, the wearable monitoring device includes an optical signal assembly configured to generate an optical signal based on a reflection or transmission of light from a detected travel of blood and/or pulse wave of the user and received by one or more sensors disposed along the user's extremity. A processor calculates the physiological characteristic and/or response, for example, heart-rate, heart-rate variability, blood pressure, stress intensity level, or energy level of the user, based on the generated signal from the sensor and user data. |
