Abstract: Tools, strategies, and techniques are provided for remote, early detection of patient health condition based on deviations from established patterns of patient movement or other activity. Once established, a patient activity signature can be compared to observed patient behavior to detect unacceptable or unexpected deviations from the activity signature. Deviation from a patient movement signature can be detected and can cause an alert or other notification to be generated or communicated to a physician, for example, or other appropriate health care providers.

Abstract: A method and apparatus for mediating a biofeedback session with a human subject in which measurements of electrophysiological quantities are used to control the presentation to the subject of a series of audiovisual sequences of varying levels of relative speed and audio composition. The sequences are real scenes designed to induce a desired psychological state when viewed. As the subject succeeds in altering his physiological parameters, the speed and audio portion of the presented scene improve as an indication of success. By using the invention, the subject develops a conditioned response to the scene and is able to control his physiological parameters even when away from the apparatus by remembering the audiovisual sequences used during treatment.

Abstract: A method and apparatus for mediating a biofeedback session with a human subject in which measurements of electrophysiological quantities are used to control the presentation to the subject of a series of prestored audio-visual sequences of varying levels of clarity resident on a direct-access video storage device. The sequences are real scenes designed to induce a desired psychological state when viewed. As the subject succeeds in altering his physiological parameters, the clarity of the presented image and sound improve as an indication of success. By using the invention, the subject develops a conditioned response to the scenes and is able to control his physiological parameters even when away from the apparatus by remembering the audio-visual sequences used during treatment.
