Abstract

Abstract A bio-feedback method for training persons in the self-regulation of physiological functions by means of displaying to the person a continuous representation of a value of such physiological functions upon, and together with, a metric which is continuously and automatically variable as a function of such values and the rate of change of such values so as to provide to the person a display in which changes in the physiological function are highly resolvable and therefore easily noticed, and apparatus for practicing such method and disclosed. Means are also optionally provided additionally displaying a target or goal to which the person is to attempt to direct the value of the physiological function; the target is automatically adjusted as a function of the value of the physiological function in such manner that it appears that the target is attainable, but is readjusted to prevent actual attainment of the target. If desired, the target may used without the automatically adjusted metric. In practicing this invention, a physiological function is detected and digitized into a stream of digital signals representing a value of the physiological function over time. Statistical functions of the stream of digital signals are determined to establish the optimal metric and target for use with the physiologic data detected from the person at any point in time, and a simultaneous display of the values of the physiologic function and either the metric, the target, or both, is generated.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 167 words
A method of teaching self-regulation to a human subject of said subjects various physiological functions comprising the steps of; (a) detecting a signal from said subject of a physiological function sought to be regulated (b) digitizing said signal to provide a plurality of digitized signals overtime (c) electronically deteriming a plurality of values, each value functionally related to a number of said digitized signals (d) automatically determining a first statistical function of said digitized signals indicating whether said subject could adequately resolve the display of said values within scaling limits extending from an upper limit to a lower limit of a metric (e) determining second statistical function of said digitized signals indicating whether said values will continue to fall within said scaling limits of said metric (f) determining said scaling limits of said metric as a function of said first statistical function said second statistical function; and (g) displaying simultaneously said metric, its scaling limits, and said values to induce said subject to control said physiological function.
Claim 2
Independent Claim 167 words
A method of teaching self-regulation to a human subject of said subjects various physiological functions comprising the steps of; (a) detecting a signal from said subject of a physiological function sought to be regulated (b) digitizing said signal to provide a plurality of digitized signals overtime (c) electronically deteriming a plurality of values, each value functionally related to a number of said digitized signals (d) automatically determining a first statistical function of said digitized signals indicating whether said subject could adequately resolve the display of said values within scaling limits extending from an upper limit to a lower limit of a metric (e) determining second statistical function of said digitized signals indicating whether said values will continue to fall within said scaling limits of said metric (f) determining said scaling limits of said metric as a function of said first statistical function said second statistical function; and (g) displaying simultaneously said metric, its scaling limits, and said values to induce said subject to control said physiological function.
Claim 3
Dependent Claim 20 words
The method of claim 1 including additionally the step of setting initial values of said upper and lower scaling limits.
Claim 4
Dependent Claim 53 words
The method of claim 1 wherein said step of determining said scaling limits more particularly comprises: establishing the difference between said upper limit and said lower limit as a function of said first statistical function; and establishing the magnitudes of said upper and lower limits as a function of said second statistical function.
Claim 5
Dependent Claim 37 words
The method of claim 3 wherein said step of determining a first statistical function more particularly comprises computing the standard deviation of said number of said digitized signals included in the determination of each of said values.
Claim 6
Dependent Claim 53 words
The method of claim 5 wherein said step of determining a second statistical function more particularly comprises computing from said number of digitized signals included in the determination of each of said values the expected magnitude of said digitized signals included in the determination of the next value of said plurality of values.
Claim 7
Dependent Claim 58 words
The method of claim 1 including additionally the steps of: automatically determining a third statistical function of said digitized signals; generating from said third statistical function a target value toward which said subject is to attempt to direct said values by controlling said physiological function; and displaying simultaneously said metric, its scaling limits, said values, and said target.
Claim 8
Dependent Claim 47 words
The method of claim 6 further including the step of continuously recomputing said third statistical function for each of a second number of said digitized signals whereby said display of said target is moved to continuously motivate said subject in the task of controlling said physiological function.
