| Abstract | Structural 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.
