BACKGROUND

Field

Example embodiments in general relate to a bioelectrical signal controlled exercise machine system for allowing an exerciser to control the state of an exercise machine and exercise environment.

Related Art

Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field. Those skilled in the art will appreciate that exercise machines generally provide for exercisers to change resistance settings based on their strength, size, training objectives, and other conditions unique to each exerciser.

Typically, exercisers use exercise machines for a period of time necessary to realize their workout objectives. For instance, an exerciser may perform ten repetitions of an exercise at one particular weight or resistance setting, then stop the exercise to change the weight or resistance to a different setting, then perform more repetitions of the same exercise at the new weight.

The intermittent cycle of “exercise-stop-exercise” breaks the continuity of the exercise routine, and injects considerable non-exercise time into the duration of the exercise session. This “down-time” during which an exerciser is changing the machine settings is effectively lost. Therefore, an exerciser desiring to exercise for forty-five minutes would necessarily spend more than forty-five minutes for their session in order to account for the down-time. On the other hand, a gym owner looks at exerciser's “down times” as lost profits. When exercisers occupy a machine for a longer period, fewer people are able to use the machine during the course of any given day.

SUMMARY

An example embodiment of the present invention is directed to a bioelectrical signal controlled exercise machine system. The bioelectrical signal controlled exercise machine system includes an exercise machine, a bioelectrical sensor device and a control unit in communication with the bioelectrical sensor device and the exercise machine. The control unit is adapted to receive data from the bioelectrical sensor device relating to measured bioelectrical signals of the human exerciser, and wherein the control unit transmits a control signal to the exercise machine to change the state of the exercise machine based on the data from the bioelectrical sensor device.

At least one embodiment of the present invention is a new and novel system and method providing for an exerciser to set or change their entire exercise experience, and more specifically change one or more elements of the exercise environment by means of transmitting electrical signals generated by one or more electrodes or microphones placed on an exerciser's body.

At least one embodiment of the present invention comprises the use of a plurality of electrodes that sense electrical energy generated by the brain and/or muscles, and transmit the amplified signal to a processor and controller to selectively change two or more elements related to the exercise environment. Additionally, at least one embodiment of the present invention provides for the use of voice commands to control additional elements related to the exercise environment.

The elements of a typical exercise environment, preferably in a gym or similar fitness facility, include the lighting of the facility, the heating or cooling level, music intended to establish an exercise tempo, weight or resistance settings that are continually changed for different exercises, or to accommodate exercisers of different strength levels, and the sequence of exercises that would be performed over the course of the intended exercise period.

One embodiment of the present invention uses two or more electroencephalogram (EEG) electrodes, and/or two or more surface electromyography (EMG) electrodes, and/or a voice-input device, individually or together which sense electrical signal inputs generated on demand by the exerciser, in order to control a multiple of elements of the typical exercise environment as just described.

One embodiment of the present invention is a new and novel method of controlling two or more discrete elements of the exercise environment, input into the system preferably comprises at least discrete input sources though not required. Therefore, the multi-channel input into the controller of the embodiment may be preferably expressed as one of the following:

• • EEG1 and EEG2=two discrete output control signals.
  • EMG1 and EMG2=two discrete output control signals.
  • EEG and MIC (microphone)=two discrete output control signals.

Using the simple formulae just described, a larger number of control signals driving various changes to the exerciser environment may be generated by an expanded formula that may consist of multiple source inputs. For example, control signals (CS) controlling seven different exercise environment variables may rely on sensor inputs consisting of:

• • EEG1; EEG2; EMG1; EMG2; EMG3; EMG4; MIC1=CS1; CS2; CS3; CS4; CS5; CS6; CS7

An EEG detects electrical activity in the brain using small conductive electrodes in contact with the scalp. Two EEG electrodes are required to read electrical brain activity, the two electrodes comprising one channel. Therefore, an EEG “helmet” or headband worn by the exerciser provides for retaining a multiple of electrodes, and maintains those electrodes in communication with the scalp to thereby generate at least two output channels.

When EEG tests are performed in a clinical environment, for instance, at the neurology department in a hospital, the patient typically lays quietly, without movement, so as not to disrupt the signals. However, in an exercise environment, exercisers are physically active while performing exercises. This high intensity muscle movement generates electromyography signals that can degrade the electroencephalograph signals. Spurious signals that degrade EEG signals are referred to as artifacts.

Artifacts typically encountered in an exercise facility include:

• • Artifacts with movement of the electrodes—which occurs during exercise,
  • Artifacts from EMG signals generated by activity of muscles close to EEG electrodes,
  • Artifacts with ambient 110V power in facility
  • Artifacts from poor/loss of electrode grounding that can result in spikes of up to 50-60 Hz.

EMG tests for athletes are well known by those skilled in the art. Motor neurons are electrical signals that cause muscles to contract. Therefore, higher value electrical signals are produced by the muscles being contracted. The electrical potential of the muscle membrane ranges from 50 μV, and up to 20 to 30 mV depending on the muscle activated. Similar to EEG signals that are continually generated based on a person's mental and physical activity, EMG signals are inherently generated whenever muscles contract. Also similar to EEG signals, a person can intentionally contract a muscle as a mind-commanded means of generating a specific on-demand electrical signal that can be used to control an event.

Therefore, the embodiment of the present invention as just described further provides for the use of EMG as another mind-initiated, on-demand generator of electrical signals that control specific events while at the same time, allowing the exerciser to continue to exercise. Such events may include for instance, increasing the volume of music playing, or changing the resistance level of an exercise machine.

It is well known to those artisans that all EEG and EMG signals have the potential to degrade as a result of artifacts. It was therefore discovered that the use of more than one type of electrode, and the use of multiple electrodes provided a larger number of data streams that, when analyzed together, help reduce the occurrence or impact of artifacts, and provide a means to validate the mind-controlled signals used to modify the exerciser's environment.

Anticipating a large number of artifacts that could degrade the EEG signal, various embodiments provide for at least one algorithm that incorporates amplification, buffering and low pass filtering of the EEG signal to increase the signal to noise ratio between the EEG and artifact signals, and smoothing of the wave form to normalize out of character data, thereby reducing the influence of artifacts on the desired channel signal.

Various embodiments provide for yet a third method of generating a mind-controlled signal. By means of a throat microphone, the exerciser may elect when to speak, and specifically what word to speak, thereby activating a voice recognition circuit that creates an output signal correlating to one or more words programmed into a voice actuation processor. The voice-actuated control may be used in conjunction with EEG and EMG signals. For instance, an on-demand mind-generated alpha wave may actuate a motor to increase the angle of the exercise plane fro the horizontal. While the exerciser maintains the brain wave level, the motor will continue to increase the exercise angle. By speaking a preprogrammed word, for instance “stop”, the exerciser can override the EEG signal and cause the inclination to temporarily stop at the desired angle.

As can be readily appreciated, an exerciser, while exercising, may concentrate on various thought, muscle contraction and/or voice command actuation of one or more control signals, all of the control signals being thought stimulated, to control one or more elements of the exerciser's environment.

More specifically, the various embodiments teach one or more systems that will allow an exerciser to automatically change the various settings on an exercise machine, change music or tempo of sounds listened to during exercise, change the ambient room temperature or change room lighting simply by training their mind to actuate one or more neurobiological or voice sensors

As can readily be appreciated, the new and novel method of mind-controlling exercise machine settings allow the exerciser to continue exercising without interruption, and without removing their hands from an exercise machine in order to physically change machine settings or other elements of their exercise environment.

Therefore, one exemplary embodiment of the present invention is system and method providing for an exerciser to control elements of their exercise environment by means of intentionally increasing ionic current within the certain neurons of the brain, the current being sensed by EEG electrodes in contact with the exerciser's scalp.

Another exemplary embodiment of the present invention is system and method providing for an exerciser to control elements of their exercise environment by means of intentionally thinking about, and therefore contracting specific muscles to increase neuromotor electrical signal levels as sensed by EMG electrodes placed in contact with the exerciser's scalp or face.

Another exemplary embodiment of the present invention is system and method providing for an exerciser to control elements of their exercise environment by means of intentionally thinking about, and therefore speaking certain words into a microphone, the words having been preprogrammed to correlate to actuation of a specific output signal that controls one or more elements of their environment.

Another exemplary embodiment of the present invention is a system and method providing for an exerciser to think about, and therefore control elements of their exercise environment without the use of their hands, by means of actuating one or more EMG, EEG and/or microphone sensors worn by the exerciser.

Yet another exemplary embodiment of the present invention is a device worn about the head of an exerciser, the device containing at least a power supply, a plurality of electrodes capable of generating at least two channels of signals, the electrode pairs comprising EEG electrodes, EMG electrodes, a means of amplifying the electrode signals, and a means of transmitting the signals to a signal processor.

Another exemplary embodiment of the present invention is a device worn about the head of an exerciser, the device containing at least a power supply, a microphone, a plurality of electrodes capable of generating at least two channels of signals, the electrode pairs comprising EEG electrodes, EMG electrodes, a means of amplifying the electrode signals, and a means of transmitting the signals to a signal processor.

Yet another exemplary embodiment of the present invention is at least signal conditioning algorithm that processes EEG and/or EMG signals to substantially reduce the detrimental effects of artifacts that are increasingly present when neuromotor and other neurobiological signals are sensed on a rapidly moving exerciser during exercising.

These and other embodiments will become known to one skilled in the art, especially after recognizing the commercial value of exercisers being able to control exercise machine settings and other elements of their exercise environment simply by thinking about changing one or more elements, the control means thereby reducing the total exercise period by eliminating any interruption of their exercise routine to manually change any machine or other settings. The time-savings of the present invention correlate positively to increased profits for the gym facility in which the present invention is implements as a means to control elements of each exerciser's environment. The present invention is not intended to be limited to the disclosed embodiments.

DETAILED DESCRIPTION

An example bioelectrical signal controlled exercise machine system generally includes an exercise machine, a bioelectrical sensor device and a control unit in communication with the bioelectrical sensor device and the exercise machine. The control unit is adapted to receive data from the bioelectrical sensor device relating to measured bioelectrical signals of the human exerciser, and wherein the control unit transmits a control signal to the exercise machine to change the state of the exercise machine based on the data from the bioelectrical sensor device.

The phrase “exercise environment” is used herein to mean one or more of any physical element with which an exerciser engages before, during or after exercising on an exercise machine in a gym facility, examples of which include but are not limited to resistance setting, weight setting, attitude of the exercising plane, room temperature, room lighting level, type or volume of music. Audible or visual cues to exercise tempo, and type of exercises and the sequence of exercises performed during a workout session, each of which may be referred to as a environmental “element” without specificity as to which element is being referred to unless a specific element is named.

Control circuits are well known to those skilled in the art. It should be noted that it is not the objective of the embodiments herein to limit the architecture or function of a control system of any particular control system design or method, but rather to broadly describe the applicability of control systems when used to change elements of an exercise environment which may include but not be limited to switches, solenoids, potentiometers, and valves. The broadest interpretation should be given to control systems as they may apply to controlling any element of the exerciser's environment.

FIGS. 1a-1c are exemplary diagrams illustrating various elements related to and exerciser's environment. During the course of a typical exercise routine, exercisers must address various elements of their environment in order to benefit from their workout. Other elements are typically out of the hands of exercisers who must rely on the gym establishment to.

More specifically, a typical exerciser 100 exercises on a substantially horizontal plane 101. During the exercise, the exerciser will select a certain weight 102 that provides a resistance equivalent against which they will exercise muscles. In some environments, the exerciser will hear music 103 that motivates the exerciser or establishes an exercise tempo 104.

One embodiment of the present invention provides for an exerciser to modify the elements of their exercise environment, hands-free, by controlling the elements with their mind. For instance, the exerciser can select a heavier weight 106 by concentrating on an actuation means to change the machine resistance settings. The exerciser may also focus thoughts so that actuators change the substantially horizontal exercise plane to an inclined plane 105, while at the same time providing the exerciser a hands-free means to change the music 108 by actuating a music control circuit. The exerciser may also change the room lighting from bright light, to dimmed light 107, while at the same time allow the exerciser to increase the frequency, and hence tempo 109 of an audible sound.

Although not exhaustive, typical elements encountered in their exercise environment are listed in the exercise environment chart 110. It is preferable that each and every one of these elements be modifiable by an exerciser from time to time during their exercise routine, and especially without having to stop the routine, dismount the exercise machine, make any preferred adjustment, then re-mount and re-start their routine.

FIG. 2 is an exemplary diagram of a brain wave frequency chart. More specifically, healthy human brains generate different brain waves at different frequencies and amplitudes throughout the day, depending on their activity. Electrical signals increase as groups of neurons are accessed to perform a function. Brain wave rhythms are generally accepted to include alpha, beta, gamma, delta and theta waves 200, each with a corresponding frequency range 201, and a fluctuation amplitude 202. As can be readily seen in the chart, the amplitude changes 203 in each of the rhythms correlate to mental activity.

At least one embodiment therefore provides for EEG electrodes to sense, record and transmit brainwave fluctuations that correspond to certain brain activity, the EEG signals ultimately controlling various circuits to change elements of the exerciser's environment. As an exerciser practices mental activity to actuate a control circuit, they become better at controlling changes in brainwave activity upon demand.

For example, an exerciser who wanted to increase the exercise resistance of a machine may focus on changing their alpha and beta wave amplitude in order to actuate a circuit that would change the resistance. If the control circuit is triggered when there is a maximum differential between alpha and beta brainwaves compared to the running normal difference between these rhythms, the exerciser may lower their alpha amplitude by increasing their mental focus and visual interaction with their surroundings, while at the same time increasing beta by exerting mental efforts and visually engaging with their surroundings.

FIG. 3 is an exemplary diagram of a representative exerciser 300 wearing a bioelectrical sensor device 310 to measure electrical signals from the exerciser's body. (e.g. an electroencephalograph electrode outfitted headband). More specifically, one embodiment of a headband of the present invention comprises an adjustable band 301 (e.g. elastic and stretchable such as an elastic headband), one first EEG electrode 302, one second EEG electrode 303, one ear clip electrode 305, and a power supply and signal transmission means 304.

During exercise, at least two electrodes record and transmit to a computer EEG signals related to neuron activity proximal to the electrodes. The two electrodes create a single channel for communicating the signal to a computer via a wireless communication means. Although a single channel comprises two electrodes, a headband providing for a plurality of electrodes that output at least two channels is preferred.

Many different types of EEG headbands or helmets are known to those skilled in the art, many of which are cumbersome, require a laborious setup protocol, and many of which are hard wired to a receiving computer. However, many of these types of EEG helmets or sensors are not conducive for use in an exercise environment. It is preferred that the exerciser, who is highly mobile when exercising, wear an EEG headband that is light weight, provides for the minimum number of electrodes required to control the desired number of circuits, and that is in wireless communication with the system controller.

FIG. 4 is an exemplary diagram illustrating differences in brainwave frequency response during exercise. More specifically, the chart 400 displays actual EEG signals that were obtained through testing on an exerciser wearing a light weight, wireless EEG headband as previously described. During exercise, the amplitude of the alpha and beta waves were independently recorded. In many cases, it can be seen that the amplitude changes of the two rhythms were very similar. In one instance, 402, the amplitude of the average alpha far exceeded the amplitude of the beta at the same point in time during the test. This differential occurred within approximately two seconds, and may be attributed to an artifact.

More importantly, while alpha generally exceeded beta in amplitude, a condition occurred wherein the exerciser maintained a significant amplitude increase in beta relative to alpha 401. The duration of this condition exceeded five seconds, illustrating a consciousness on the part of the exerciser to focus on intensifying beta activity. One embodiment of the invention recognizes this preferred condition for a predetermined minimum time duration, activates a circuit that controls the change in one element of the exerciser's environment.

FIG. 5 is an exemplary diagram of a representative exerciser 200 wearing an electroencephalograph and electromyography electrode outfitted headband 503. It can be readily seen that the headband provides for multiple channel outputs that, correspondingly, control multiple elements of the exerciser's environment by generating thought-activated signals. The headband comprises at least two EEG electrodes 202, and at least two EMG electrodes 500. It is well known that EMG electrodes record neuromuscular electrical signal activity of the muscles proximal to the electrodes. As a means to provide for more than one EMG channel, a chin strap comprising at least two EMG electrodes 501 placed proximal to mandibular and temporal muscles allow for the exerciser to increase electrical signal levels, and therefore control specific control circuits by intentionally focusing thoughts on activating the targeted muscles by flexing their chin, of clenching their teeth. In practice, data received from all of the electrodes is amplified and transmitted wirelessly in real time from the headband to a receiver and controller.

Therefore, the headband and chin strap comprising multiple EEG and EMG electrodes provides for an exerciser to thoughtfully actuate a plurality of control circuits during exercising, each control circuit thereby preferably controlling one of multiple elements in their environment. U.S. Pat. No. 8,812,075 to Neurosky, Inc. discloses an exemplary sensor headset suitable for use with the various embodiments of the present invention and is hereby incorporated by reference herein. U.S. Publication No. 2014/01487,15 filed by Neurosky, Inc. discloses various types of biosensors that are suitable for use with the various embodiments of the present invention and is also hereby incorporated by reference herein.

FIG. 6 is an exemplary diagram showing a multi-channel mind controlled exercise machine adjustment system. A headband as previously described provides for a plurality of sensors including two channels of EEG electrodes 600, electrodes for one EMG channel 601, and an audio sensor device 602 (e.g. a throat microphone 602). It should be noted that the configuration of input sensors is not meant to be limiting, and any number of any combination of any of the sensors just described may be used in a multi-channel mind controlled exercise machine.

An exerciser may actuate each or all of a plurality of channels by focusing one or more thoughts toward generating increased electrical activity in the brain, in muscles by intentionally stimulating one or more muscles, and/or by consciously considering a particular voice command correlating to controlling a specific desired element of their exercise environment.

Amplifiers 603 provide for increasing the signal strength of the neurobiological signals detected by the electrodes. Further, filters, such as low pass or high pass filters provide for scrubbing artifacts from the electrode-input electrodes. Depending on the brain wave rhythm preferred for processing as a mind controllable signal, the high pass or low pass filters, and in some cases both filter ranges will be used to attenuate the artifacts. Filters are preferably used to clean the signal from EMG electrodes as well, the filters being selected based on the frequencies of the desired and non-desired ranges.

The amplifiers and filters just described may be integrated into EEG and EMG electrode modules, and may not be discrete components through which the neurobiological signals pass. Those skilled in the art will appreciate that microphone circuits are well known, and any recognized circuit may be used for receiving and communicating a voice input to a signal acquisition module 605 preferably affixed to the headband. The acquisition module further provides for multiplexing a plurality of EEG, EMG and mic signals, all of the signals together being transmitted to a controller module by means of an RF transmitter 606. The RF signals may be transmitted to the controller by communication wire, but are preferably communicated via a wireless communication link 607.

An RF Receiver circuit 608 receives the multiplexed signal. An analog to digital circuit 609 converts the signals to digital format for processing by a digital signal processor 610. The process of receiving, converting and processing analog signals is not meant to be limiting. The large body of art is well known, and any recognized receiving, converting and processing circuit may be used without no effect on the intended function of the various embodiments of the present invention.

A multi-channel controller 611 provides for processing each of the received signals to activate a specific circuit that will control its respective element. In practice, and merely for example, a first EEG channel A may be used to actuate a motor to increase the angle of an exercise platform, while a second EEG channel B is used to increase the music volume of the exercise music. A third channel C from EMG electrodes may be used to increase the resistance setting of the exercise machine. Each of the channels just described would be actuated by various means practiced by the exerciser, including placing their mind is a meditative state with eyes closed in order to increase alpha amplitude relative to beta, the predetermined differential being achieved thereby triggers the respective output control signal. A second condition wherein the exerciser opens their eyes and focuses on the machine element, and strongly visualizes a change in machine attitude increases the beta signal amplitude relative to the alpha, the predetermined differential being achieved thereby triggers its respective output control channel.

In both of the just described cases, once the intentional thought process actuates the control output signal, for instance, a motor that turns on to elevate the exercise machine, the switch could remain open until the exerciser speaks a control word “stop” into a microphone, the word having been preprogrammed to terminate any EEG or EMG originated control signal.

Although many variations of the system of controlling a plurality of control signals that modify one or more elements of the exerciser's environment may be used without deviating from the purposed function of controlling signals using mind-originated thoughts, and the headband and/or variations of the headband previously described by rely on one or more channels generated by EEG, EMG and/or mic signals, independently or in combination with one another, to describe every possible configuration and circuit design would be burdensome, but would nevertheless illustrate the broad application of the new and novel method of exercisers being able to mind control many elements within their exercise environment, hands-free, and on demand during the course of their exercising.

FIG. 7 is an exemplary diagram showing one system and method of translating EEG signals into a control circuit to adjust an exercise machine. A software program for a control circuit is launched 700 wherein brainwave signal input variables are defined, time periods during which the brainwave signal must be received to create a result, and terminal contacts for a serial port output are defined.

Not shown, a headband with at least two EEG electrodes is affixed to an exerciser, and is powered on so that neurobiological electrical signals are sensed by the electrodes. Signals received by the electrodes are communicated to the control circuit 701 and parsed into the various rhythms including alpha, beta, gamma, theta and delta, all of which are characterized by different frequencies. The selected frequencies being defined in the setup 700 establish the rhythms that will be used by the controller 704 to control the machine function.

Presented as one example, alpha “A” and beta “B” frequencies are used in the illustration. The electrode-sensed signal amplitude changes of the A and B frequencies are monitored over time, with normalization of the signal by the controller to compute a running average of the amplitude changes as a means of smoothing what are oftentimes highly erratic signal changes. The smoothed data stream thereby becomes a more reliable data source upon which to apply control function rules.

At the start of the exemplary exercise, an exerciser is positioned on an exercise machine positioned on a substantially horizontal plane. Various rules, having been previously established, provide for signal conditions that correlate to controller function. For instance, a first rule establishes a T/F gate that compares amplitude changes of A and B frequencies. If A does not equal B, an switch 707 is opened to allow for machine control. If A equals B, the switch is closed 705 and a “null” control event 706 will be triggered.

A positive result from one rule 708 will cause the controller to actuate a motor that inclines an exercise platform. This rule requires the exerciser to establish and maintain for at least 5 seconds a condition where the amplitude change of B (plus an error margin) is greater than the amplitude change of A. As one method discovered during experimentation, an exerciser may achieve this condition while exercising by staring intensely at one end of the machine, and visualizing that end of the machine being elevated by the motor. This mental exercise is just one proven example of how to reduce the amplitude of the alpha frequency, while elevating the amplitude of the beta frequency. A positive result from another rule 709 means that the amplitude changes of A and B are substantially equal, indicating that no control signal is desired by the exerciser. The control circuit defaults to a “null” status and ne event is triggered.

Yet another rule 710 is established so that an exerciser can reverse the inclination of the exercise machine. More specifically, if the amplitude of the B frequency is less than the amplitude of the A frequency for a period of not less than 10 seconds, the inclined machine will begin to decline to a new position of one “increment”. An increment may be defined as a 5-degree incline or decline, but the actual increment amount is irrelevant, and any preprogrammed increment may be used. As one method discovered during experimentation, an exerciser may achieve this condition while exercising by closing their eyes and meditating on the wind-down of one exercise, relaxing and reducing overall muscle activity prior to starting the next exercise in a sequence of exercises. This mental exercise is just one proven example of how to reduce the amplitude of the beta frequency, while elevating the amplitude of the alpha frequency.

A final rule 711 is used to anticipate the end of an exercise routine by concluding that the reduction in muscle activity, and the eyes-closed meditation condition is persisting for more than 30 seconds. As a result of a positive result of this rule, the inclined exercise machine begins to return to its horizontal starting point, readying for exerciser dismount.

As can be seen, the exerciser, through the use of mental imaging, is able to increase or decrease the incline of an exercise machine. It should be noted that machine incline is but one of many elements of an exercise environment, and the control signals and rules of the immediately preceding example may be modified to apply to controlling an element other than machine incline or decline.

FIGS. 8a-8c are exemplary diagrams showing a representative exerciser wearing a throat microphone, and a list of voice command instructions, and a block diagram of a control circuit for adjusting an exercise machine.

As another means of controlling elements if an exercise environment, an exerciser 200 is shown with a band 800 affixed to the neck. A microphone 801 is retained by the band, securing the microphone against the skin proximal to the vocal cords. Throat microphones are well known by those skilled in the art, and are frequently used as a hands-free communication means.

Used separately, or in conjunction with an EEG and/or EMG headband, the throat microphone provides for an exerciser to thoughtfully consider what element of their environment that prefer to change, and remembering a series of word or phrase commands 802 can actuate a controller function via a voice recognition circuit not shown. A list of controller functions 803 is shown but is not intended to be limiting. Any element of the exercise environment may be controlled by a voice command separately or in conjunction with EEG and/or EMG input.

As one example of a voice recognition module activating multiple controller output signals, a control module 804 is installed on an exercise machine not shown. The microphone is in wireless communication with a voice signal receiver module 805 that incorporates an A/D conversion circuit, a preprogrammed processor 806 containing a list of recognized words and the associated instruction that are communicated to a multi-function controller 807.

Six controller output signals 808 are shown, but ten or more output signals are possible, each controlling a different element of the exerciser's environment. The number of controller output signals is limited only by reason of the number of elements desired to be controlled. It is preferable, however, that the controller 807 processes only one input request at a time, with a reasonable delay prior to initiating the next command in a string of voice commands.

As one illustration of the use of mind-initiated voice control in conjunction with mind-initiated EEG controls, the exerciser, having initiated the elevation sequence by meeting the B>A EEG rule (FIG. 7, 708) desires to stop the elevation actuator prior to the elevation reaching a predetermined increment. By initiating a voice command, for example “stop elevation”. As shown in the drawing, the command sends an interrupt instruction 808 to the elevation controller, thereby providing the exerciser with multiple method of mind-controlling the machine elevation element of their exercise environment.

As will be appreciated by those skilled in the art, providing exercisers with the ability to mind-control a plurality of elements within their exercise environment allow exercisers to continue exercising without interruption while changing any element desired. The increased efficiency and mind-machine engagement reduces the overall workout time by eliminating the traditional start-stop sequence required whenever an exerciser changes a machine setting. Further, they will appreciate that the reduced exercise time provides for a gym facility to conduct more exercise classes within any given period of daily operation, thereby creating more operating revenue and profit.

The various embodiments of the present invention use a sensor unit 310 that preferably uses a bioelectrical sensor device 320 that is adapted to detect a bioelectrical signal of a human exerciser before, during and after the performance of an exercise. The bioelectrical sensor device 320 includes one or more of each of the following types of biosensors: an electroencephalography (EEG) sensor, and an electromyography (EMG) sensor. The bioelectrical sensor device 320 is adapted to communicate with the control unit by wired or wireless communication. The sensor unit 310 may also include an audio sensor device 602 that is in communication with the control unit 620 and is adapted to receive audio commands from the human exerciser as illustrated in FIG. 8b of the drawings.

A control unit 620 is in communication with the bioelectrical sensor device and the exercise machine (wirelessly and/or wired communications). The control unit 620 is adapted to receive data from the bioelectrical sensor device 320 (and audio sensor device 602) relating to measured bioelectrical signals of the human exerciser. The control unit 620 transmits a control signal to the exercise machine 900 to change the state of the exercise machine based on the data from the bioelectrical sensor device 320 to perform the desired function by the exerciser. The control unit 620 controls the actuators 910, 910a, 910b of the exercise machine to control the pitch, roll and/or yaw of the exercise machine (or any combination thereof). The control unit 620 further can control the resistance level provided to the carriage by the resistance device 920.

In addition, the control unit 620 may transmit a control signal to various other environmental systems in the building where the exerciser is performing an exercise such as, but not limited to, the HVAC system 980 (to control temperature and climate conditions), the sound system 982 (to control volume and the type of music playing during the workout) and room lighting 984 (to control the level and type of lighting in the room).

To use the various embodiments of the present invention, the bioelectrical sensor device 320 and/or audio sensor device 602 are physically connected to the human exerciser. The exerciser performs an exercise on the carriage 903 of the exercise machine 900. The bioelectrical sensor device 320 detects one or more bioelectrical signals of the human exerciser which are used by the control unit 620 to calculate and determine how to control the exercise machine 900 (e.g. lift, lower, roll to the right, roll to the left, increase resistance, lower resistance) and/or various environmental elements (e.g. lighting, room temperature, song choice, music level). The control unit 620 transmits the appropriate control signal(s) to the exercise machine and/or various environmental elements based on the detected bioelectrical signal(s). For example, the control signal adjusts a state of the actuator 910, 910a, 910b to correspondingly adjust the attitude of the exercise machine (e.g. pitch, roll and/or yaw).
