Inventor(s)Silverman; Gordon (New York, NY); Brudny; Joseph (New York, NY)
AbstractStructural systems and method are employed including a multiplicity of computers to control the acquisition and enhancement of skilled performance or behavior. Preprocessing computers (8 and 24) each accept signals from any corresponding one of a variety of physiological or other signal transducers either in close proximity to the computer or transmitted to the computer via a telemetering system. The preprocessing computer calculates a number of different measures of this signal and makes the results known to one or more other computers. These other or auxiliary computers control presentation of a display of the data for a human observer, and perform additional calculations which determine if the processed data is within a predetermined range. This range may be a function of time and/or other variables. A measure of the error between the allowed range and the processed data is computed within these auxiliary computers. These results may be used to alter the display. They are also returned to the preprocessing computer where they may alter the preprocessing calculations. Alteration of the display and the preprocessing calculations are adapted to improve skilled performance and behavior without the intervention of a human operator other than the user.

BACKGROUND OF INVENTION

In the past, the introduction of signals which are electrical analogs of physiological signals into a computer or display has been used primarily for one of three purposes.

(1) Acquisition of data concerning physiological and/or behavioral responses, possibly to some external stimuli.

(2) Physical rehabilitation of human subjects who have lost motor control as a result of some injury or insult to the central nervous system or other parts of the body.

(3) Psychological treatment of altered behavior due to heightened anxiety and stress.

Computer application in the fields of science and medicine led to tremendous advances in these areas. However, these advances have not yet been adapted or reflected in the methodology of instructing people to improve their fitness or performance in sports. In man, the effectors of behavior are primarily the muscles. Their skillful use, in terms of appropriate spatio-temporal and coordinated activity requires learning that leads to eventual patterning or automatic responses. Acquisition of skill is accomplished through very many successful, and properly identified to be successful, repetitive trials. Skill enhancement maximizes the role of the effectors of behavior (muscles) and adds to well-being and fitness.

PRIOR ART

There are many skill enhancement machines and systems designed to improve athletic and/or other performance or behavior in healthy, normal individuals. Such presently available systems, however, suffer from a number of limitations. Most do not employ computers for learning, offering only various types of mechanical resistance to cause muscular contractions. The inherent inability of human beings to finely quantify effort without on-line, real-time augmented feedback makes such contractions either excessive and too widely spread or too inadequate to be effective. The ones that employ computers, use "off-line" techniques for the improvement of skilled behavior. This means that skill improvement occurs as a result of a sequence of operations (knowledge of results). Thus and first, performance or behavioral data is acquired from a subject and stored in a computer. Next, the data is reviewed (after the activity has been completed) and adjustments in the performance are determined. This process is repeated until some behavioral goal is achieved. The delay in the feedback of behavior has been demonstrated to be ineffective for learning or improving skilled performance.

Other machines display a measure of the subject's performance but these may not provide behavioral goals. Thus, a human operator is needed to provide for the target goals. Where the machine includes behavioral goals as part of the display, these goals are often fixed. As a consequence, the machine by itself is incapable of "adaptive" or dynamic operation. This limits the rate and level of peformance which can be achieved.

Still other machines do employ some dynamic, adaptive operation. However, these rely on behavioral measures of human performance such as position, and not on underlying physiological signal sources. A subject training signal is provided only when performance falls outside an allowed error range. The subject is unaware of the instantaneous and continuous value of his or her error.

A primary limitation of these machines is related to their organization or architecture. Most machines include a single computer or processor which must carry out all operations associated with the acquisition of data, display of results, and calculation of performance goals. Such machines cannot perform all instructions associated with these calculations within a specified time (real time). As a consequence, the subject cannot obtain an accurate representation of his or her behavior. Results are only made available after a considerable delay in time. This limits improvement of skill acquisition.

This criticism of prior art includes typical structures, systems and methods reflected in the following U.S. patents:

Evans 3,717,857 discloses an athletic measurement system and apparatus in which a dedicated (fixed, and non-interchangeable) transducer provides definite information about flex and twist of a plate affixed to an arm or within an arm or club. Means such as a cathode ray tube or oscillograph, are included for display of a swing initiated by a human being. However, this device is limited to measurement of a single behavioral activity and provides only a fixed computation with regard to the data being generated by the human being.

Brudny 3,905,355 describes an apparatus for obtaining and displaying muscle activity at a multiplicity of points on the human body with structure to display, in a multiplicity of forms, a single measure of such activity, and includes an adjustable reference means which can be used by a human being to compare his own responses against this adjustable reference. This system includes a single computer with a single program of operations whose function is to calculate one measure of performance of EMG activity. The computer provides a single result which is used by the display alone and cannot integrate or coordinate the independent actions of other computers which can carry out distinct operations.

James et al. 4,110,918 includes portable, self-contained modular units which may be used for biofeedback training. A central processing unit can be adapted to receive inputs in a simultaneous manner from multiple portable units and provides additional refined conditioning of the signals from the portable units. However, the central processor cannot initiate, synchronize, control, nor vary the preprocessing calculations and the results generated by the portable units.

Scattergood et al. 4,136,684 provides an example of a biofeedback system which can operate over a wide dynamic range extending from one microvolt of signal to signal levels in ex
