Abstract:
A heart rate variability feedback system for a user, the system comprising:an output device configured to transmit a sensory signal perceptible by the user based on the output device receiving an activation signal;a plurality of electrodes configured to produce electrical signals based on electrical activity of the user's heart;a housing sized and configured to be worn by the user;a memory housed by the housing wherein the memory is configured to store heart rate variability feedback criteria associated with a plurality of operational modes;a mode selection device housed by the housing and configured to be operated by the user to select any one of the plurality of operational modes as a selected operational mode; anda processor housed by the housing and coupled to the plurality of electrodes, the output device, and the memory, the processor configured to receive digital signals associated with the electrical signals produced by the electrodes, the processor configured to determine heart rate variability of the user based on the digital signals and to transmit an activation signal to the output device based on whether the determined heart rate variability satisfies the heart rate variability feedback criteria associated with the selected operational mode.
