previous work by the present inventors has been published as u . s . patent application no . 2008 / 0081692 a1 , which is herein incorporated by reference thereto in its entirety . the present invention now will be described more fully hereinafter , in which preferred embodiments of the invention are discussed . this invention may , however , be embodied in many different forms and should not be construed as limited to the embodiments set forth herein ; rather , these embodiments are provided so that this disclosure will be thorough and complete , and will fully convey the scope of the invention to those skilled in the art . the present invention includes a method of transforming physiological information obtained from biomedical instruments in order to use that information to modify the functioning of computer simulation or game controllers or joysticks . the invention involves modulation that transforms the controller signals received at a computer &# 39 ; s game port or a game console prior to their being used by the computer simulation or game software . the result can be that the magnitude of the effect of the game or simulation &# 39 ; s input device ( e . g ., joystick , game pad , steering wheel ) is modulated by the strength of the physiological signal ( s ). by making the joystick &# 39 ; s “ control authority ” proportional to the physiological signal ( s ), the player is encouraged to change the physiological signals ) according to a programmed criterion ( e . g ., increase , decrease , or maintain ) in order to perform better at the game task . when the physiological signal ( s ) are the target of physiological self - regulation or biofeedback training , the game play reinforces therapeutic changes in related physiological processes . however , the reinforcing feedback is preferably implicit in the task , and not explicit in the form of direct feedback ( bar graphs , tracings ), as in conventional biofeedback training . in this way , contingencies for subtle conditioning of the desirable physiological response ( s ) are set up . different embodiments of the present invention are possible , and the components of the invention can vary depending upon implementation . further , the invention is intended to be used with a variety of systems , such as standard video game systems ( e . g ., sony playstation , nintendo , etc . ), with standard personal computer systems , and with computer simulators and professional job training systems . additionally , one or more of a wide variety of different measured physiological signals can be used in accordance with the present invention , for example , eegs , skin temperature , skin conductance , heart rate , and / or event - related potentials ( erps ). u . s . pat . no . 5 , 377 , 100 , issued on dec . 27 , 1994 to pope et al , and which is incorporated herein by reference as if set forth in its entirety , and also specifically at column 3 , line 8 to column 5 , line 60 that details a method for determining an individual &# 39 ; s eeg index of attention , which index can be used to assess his or her mental engagement in a task . in accordance with at least one embodiment of the present invention , the disclosed apparatus and methods can be used specifically for entertainment purposes . for example , a player might simply use the system for the enjoyment and challenge of mastering a game or simulation , as well as the satisfaction of controlling his own physiological states . it is also within the scope of the present invention that a player could entertain himself by personally using data feedback to set challenges , thresholds and goals for the player to achieve . further , it is within the scope of the present invention to utilize a variety of input devices or controllers , as well as to utilize not just joystick or gamepad input ports , but to utilize a variety of other computer input ports as well , and thus varying the connection apparatus , as appropriate , to accommodate the type of port and / or system being utilized . the present invention could possibly utilize interface devices such as touch pads , light pens , power gloves , keyboards and weapons ( e . g ., hand - held guns ), for example . additionally , it should be noted that when the term “ counts ” has been used herein the term potentially referred to any one of a variety of types or forms of information that a computer , video game system , and / or training simulator might receive at a computer or game port . for example , it is within the scope of the present invention that the information that the computer software reads from a port could be in the form of a digital value which can be expressed as a number , counts , etc . additionally it is expressly within the scope of the present invention that substantially all of the described hardware known to the art , for example as described in u . s . pat . no . 6 , 450 , 820 , that is incorporated in its entirety by reference herein , could be replaced with software . that is to say , for example , many functions , such as comparators , timers , threshold detectors , relays , voltage controlled amplifier , voltage controlled modulator , offset circuitry , and gates , vco , baseline deviation deriving system , etc ., can be accomplished with software . for example , these functions could possibly be programmed in what is commonly known as a “ virtual instrument ” environment , such as national instruments &# 39 ; labview . in at least one embodiment , this type of environment would allow hardware used in the present invention to be replaced by functional modules represented as icons on a screen , which can be set - up and “ wired ” together . the resulting software system can then function just like its hardware counterpart , for example , interacting with external signals through analog and digital input and output boards installed in the computer . the present invention fully integrates biofeedback training into a true dynamic video game , or realistic simulation , which turns the popular home pastime of playing video games into an opportunity for therapy or self - improvement . it is the prototype of a new generation of computer game environments that train valuable mental skills beyond eye - hand coordination . current systems typically deliver biofeedback in bland , minimally motivating task formats with direct feedback . the present invention &# 39 ; s video game or task challenge format motivates trainees to participate in and adhere to the training process through the rewards inherent in mastery of popular video games or job simulators , and without the demand , monotony or frustration potential of direct concentration on physiological signals . in accordance with at least one embodiment of the present invention , the entertainment value and social interaction experience of electronic gameplay is enhanced by distributing the control and modulation of inputs to electronic games among two or more players , so that joint game goals are collaboratively pursued and accomplished by separate players who provide different means of control and modulation . for example , one or more player may provide physical activity control via game controller ( s ) ( these players may be termed the physical operators ) and one or more other individuals influencing the game through physiological activity measured via body sensors ( these players may be termed physiological operators ). such an embodiment avoids the problem of movement disruption of physiological sensing by modulating one player &# 39 ; s game controller using the physiological signals of another , collaborating player who is physically inactive . the invention further enables collaborative team play by multiple players with different roles on the team — one or more providing physiological mastery to facilitate game performance and one or more others simultaneously providing manual or physical skills needed to operate the game . this creates richer and more complex gaming opportunities than present games provide , enabling engaging and rewarding team social interactions among people who have different skill sets and interests or who take turns playing different roles on a team — on one hand , providing the physiological self - mastery , and on the other , providing physical performance action skills . such an embodiment modulates one or more players &# 39 ; game controller ( i . e ., game input device operated by physical activity ) using the physiological signals of another / other , collaborating player ( s ) who is / are not providing input to the game via a game controller . the invention accomplishes this function by transmitting control signals , either wired or wirelessly , derived from one or more player &# 39 ; s / players &# 39 ; physiological signals to modulate the control over the game of one or more other player / players who are using electronic game controllers , in a way that either retards or boosts game performance influence of the game controllers . alternatively , this shared influence over a game of a physiological operator and physical ( game controller ) operators , respectively , can be implemented by blending influences from both into a single control input into the game ; in this manner , game action tasks could be operated either via a game controller or particular predefined physiological input , or through pre - defined combinations of both . for instance , a video game task of an avatar game character jumping over a canyon could be initiated by either the game controller operator or by a physiological operator &# 39 ; s particular body activity , and the height or length of the jump could then be solely dependent on the physiological activity of the physiological operator whereas the direction of the jump and place of landing on the other side could be controllable only by the game controller input . thus , the physiological and game controller operators will have to collaborate to succeed at the task of jumping for good success in the game . such an embodiment may be implemented in any of the above - described game systems , simply by having one player &# 39 ; s physiological signal ( s ) sensed by the physiological signal conditioning system ( e . g ., 104 of fig1 of u . s . pat . no . 6 , 450 , 820 ) and having another player control the game controller ( s ) ( e . g ., joystick 105 of fig1 of u . s . pat . no . 6 , 450 , 820 ). such an embodiment enables two new categories of electronic game play : ( 1 ) modulating one or more player &# 39 ; s game controller input using the physiological signals of another / other collaborating individuals ; and ( 2 ) modulating game activity through joint authority over game actions by game controller input from one or more individuals and physiological sensor input from other separate individuals not using game controllers . the embodiment enables physiological and manual control of electronic games to be allocated in various combinations to several players . such an embodiment permits individuals who are physically challenged to participate in electronic game play by collaborating with a player who is able to manipulate controls that the challenged player cannot , and enables individuals with different skill sets and interests ( physiological self - control vs . physical performance skills ) to join together in rewarding game play . such an embodiment also enables implementation of unprecedented electronic games that incorporate a classic motif in superhero comics and movies in which differently - abled protagonists collaborate and / or interact , such as professor x and his cohorts in the x - men series or elijah price and david dunn in the movie “ unbreakable ” and provides opportunities for new kinds of games where the application of “ mental powers ” of particular individuals ( i . e ., particular deliberately produced eeg characteristics ) can enable or enrich the performance of other individuals playing a game . all references , including publications , patent applications , and patents , cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein . the use of the terms “ a ” and “ an ” and “ the ” and similar referents in the context of describing the invention ( especially in the context of the following claims ) are to be construed to cover both the singular and the plural , unless otherwise indicated herein or clearly contradicted by context . the terms “ comprising ,” “ having ,” “ including ,” and “ containing ” are to be construed as open - ended terms ( i . e ., meaning “ including , but not limited to ,”) unless otherwise noted . recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range . unless otherwise indicated herein , and each separate value is incorporated into the specification as if it were individually recited herein . all methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context . the use of any and all examples , or exemplary language ( e . g ., “ such as ”) provided herein , is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention unless otherwise claimed . no language in the specification should be construed as indicating any non - claimed element as essential to the practice of the invention . preferred embodiments of this invention are described herein . including the best mode known to the inventors for carrying out the invention . variations of those preferred embodiments may become apparent to those of ordinary skill in the art upon reading the foregoing description . the inventors expect skilled artisans to employ such variations as appropriate , and the inventors intend for the invention to be practiced otherwise than as specifically described herein . accordingly , this invention includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law . moreover , any combination of the above - described elements in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context .
