Abstract
A portable and programmable biofeedback system which senses a physiological variable, such as heart rate, and both displays the physiological variable in a visual display in real time and activates and deactivates a user prerecorded voice-message upon reaching a user-programmed threshold value for the physiological variable measured. The system is especially useful in the field of behavior modification which require that the patient have reliable access to his or her behavior modification techniques upon onset of the symptoms associated with a diseased behavior. The invention is made up of a combination of components, namely, a biosignal sensor, a transmitter, a receiver, a processing unit capable of being programmed with a biosignal threshold value and comparing the biosignal to the threshold value, a switching circuit into which an output signal is input, and an analog or digital message recording and playback device operably linked to the switching circuit so that a playback device is activated or deactivated when the output and threshold values match. A display mechanism for visually displaying the real-time changes of the biosignal is linked to the processing unit.
