Abstract

A bio-feedback system to support the collection of a plurality of physiological parameter values of a subject being monitored. The physiological parameter values collected are processed to determine and present to the subject a continuously updated succession of presentation states, possibly multimedia in nature, in order to attempt to enhance the bio-feedback capability of the system. The system includes a digitizing camera arranged to continually capture an image of the subject. The presentation states, which include the captured image of the subject, are accented by color accents including curved bands of color coextensive with and juxtaposed to the outline of the image of the subject. The color of the bands may be appropriately altered in a predefined manner as determined by changes in the physiological parameter values collected and processed.

Claims

A bio-feedback system to enable a determination and collection of a plurality of physiological parameter values of a subject being monitored, the physiological parameter values collected, stored, and processed to enable a presentation to the subject of a continuously updated presentation state representative of a current physiological state of the subject to attempt to enhance an ability of the subject to be aware of and possibly self-alter the subject'"'"'s present physiological state, the bio-feedback system comprising:

(a) a digitizing camera arranged to continually capture an image of the subject;

(b) a plurality of physiological parameter sensors, each sensor arranged to sense at least one physiological parameter value of the subject being monitored;

(c) computing means, having the digitizing camera operatively coupled thereto to receive from the digitizing camera each captured image of the subject, and further having operatively coupled thereto the sensors to enable collection of physiological parameter values determined by the sensors that compose the physiological state; and

(d) presentation means to enable a presentation to the subject of presentation states including the captured image of the subject along with other information including physiological parameter values sensed, information computed from physiological parameter values sensed, and a trend in changes of at least one physiological parameter values being sensed;

(e) the presentation states presented to the subject via the presentation means in order to attempt to enhance the ability of the subject to possibly alter and self-regulate the subject'"'"'s current physiological state.

2. The bio-feedback system according to claim 1, where the presentation means presents a continuously updated presentation state that includes at least one of text, graphics, sound, and vibration, in addition to the captured image of the subject having color accents associated therewith, wherein the color accents displayed include at least one curved band of color coextensive with and juxtaposed to an outline of the image of the subject thereby presenting an aura associated with and representative of the current physiological state being sensed.

3. The bio-feedback system according to claim 2, wherein a color of the color accents may be appropriately altered in a predefined manner determined by the physiological parameter values received from the sensors and processed by the computing means.

(a) a plurality of contact and non-contact physiological parameter sensors, each sensor arranged to sense at least one physiological parameter value of the subject;

(b) computing means, operatively coupled to the sensors to enable the computing means to receive the parameter values sensed by the sensors and process the parameter values to determine and provide the presentation states to the subject;

(c) a digitizing camera arranged to continually capture an image of the subject, each captured image received and possibly stored by the computing means; and

(d) a display unit, operatively coupled to the computing means to receive from the computing means images of the subject captured by the digitizing camera to enable the images to be presented to the subject;

the display unit further receiving from the computing means at least one of text and graphics information, along with at least one color accent provided as at least one curved band of color coextensive with and juxtaposed to an outline of the image of the subject captured by the digitizing camera that is representative of the current physiological state being sensed.

10. The bio-feedback system according to claim 9, further including a storage unit to store at least a portion of the physiological parameter values collected, and to possibly store a plurality of the presentation states provided to the subject.

11.
