BEST MODE FOR CARRYING OUT THE INVENTION
Now, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
In this specifications, physical strength and health information means a term including all kinds of physical physiological health information, health information according to physical strength(physical strength information), all kinds of health information related to a user's body such as heart rate, respiration volume, blood pressure, weight, oxygen volume saturated in blood, momentum or exercise speed(running speed, etc.,) according to a user's exercise state, agility, momentary power, muscular power, softness, equilibrium, muscular endurance power, cardiac and pulmonary endurance power, NIBP, VO2, change in heart rate, cooperation ability of body organs, etc. Physical strength and health evaluation information to be discriminated from the above term means a result obtained about a user's health degree by analyzing the physical strength and health information. For example, in a user whose weight is heavier as compared with his age, the user's age and weight belong to the physical strength and health information and fatness, while if it is judged on the basis of these, belongs to the physical strength and health evaluation information.
First, FIG. 2 shows, as a block diagram, basic construction of a automatic physical strength evaluation and exercise system 100.
The automatic physical strength evaluation and exercise system 100 in FIG. 2 comprises an exercise equipment 10, a main controller section 20, a display device 30, a memory means 40, a physical strength and health information sensing section 50 and a load adjustment section 80.
The exercise equipment 10 may include, but is not limited to, a health bike shown as an example in FIG. 1. Physical strength and health information according to user's exercise is sensed in the physical strength and health information sensing section 50. The sensed and read physical strength and health information is transmitted to the main controller section 20, which analyzes the physical strength and health information, generates physical strength and health evaluation information about user's health state, and diagnoses the user's health state. The generated physical strength and health evaluation information is displayed in the display device 30.
Furthermore, the user executes a predetermined game stored in the memory means 40 while being exercising, in order not to feel bordom. Referring to FIG. 7, a reference person 1 and a virtual subject 2 to reflect user's momentum appear in the game, the virtual subject 2 or the reference person 1 being able to have any figure which can induce user's interest according to the conventional art, such as diverse characters, interesting animal figures, etc. Also, the user can take pictures of his own diverse figures using an image camera 36 in order to make his own appearance displayed as the virtual subject 2 to reflect the user's momentum(exercise speed). Further, it is possible to compose a predetermined background scene and his exercising appearance using a chroma-key method. a user can exercise with other users by means of a network 95 such as an internet, etc., instead the exercising together with the reference person 1, which system will be explained in detail in connection with FIG. 9.
A button input device 35 is provided so that the user may select a desired menu among diverse menus for diverse health measurement. As information to be able to be inputted through the button input device 35, there will be a diagnosis by questions about a health state, etc. The button input device 35 may comprise a selection button in the middle and a cancel button and a movement button in the left and right sides, as shown in FIG. 1. Also, a Keyboard and/or a mouse can be included as shown in FIG. 3, in order to input information such as a member ID, a password, a name, a resident registration number, sex, age, weight, height, etc. The main controller section 20 may comprise diverse menus to enable a diagnosis of the user's health state, and the physical strength and health information read in the physical strength and health information sensing section 50 according to the menus. The following example is explained so as to facilitate understanding of the invention.
The physical strength and health information sensing section 50 may comprise diverse measurement modules, an example of which is shown in FIGS. 1 and 3. The physical strength and health information sensing section 50 is installed in the exercise equipment 10, and thus it is advantageous that information about the user's self exercise state can be measured simultaneously with the user's exercising and without measuring health or exercise information separately.
For example, the weight scales may be provided in a saddle or a footboard of the exercise equipment 10. Then, user's weight can be measured by getting up or sitting on the exercise equipment 10, such measured user's weight being transmitted to the main controller section 20. Further, a body fat measurement means 52 for measuring the user's fatness, as shown in detail in FIG. 10, may be installed in a handle 11 of the exercise equipment 10. By installing the body fat measurement means 52 in the handle 11, user's fatness can advantageously be measured the during the exercise without any necessity to measure it separately.
The main controller section 20 provides the physical strength and health evaluation information aftering executing diagnosis about the user's health state on the basis of the transmitted physical strength and health information. For example, whether to be fat or not can be analyzed by only two pieces of physical strength and health information regarding body fat and weight. The more diverse the physical strength and health information to be read in the physical strength and health information sensing section 50 is, the more diverse is the physical strength and health information to be able to diagnose in the main controller section 20. For example, the main controller section 20 can calculate the rotation number of a bike wheel or a pedal and the exercise distance while the user exercises for around 12 minutes, and a Broker index(weight/(height−100)=100: 90-100: normal; 101-119: fat; 120 or the above: severe fat) can be calculated using the user's weight and height inputted through the button input device 35. Further, the body fat can be calculated using the bioelectric resistance analysis method, and the heart rate by an electrocardiogram and its change, agility about how fast the user responds to the given situation, etc., can be measured.
In FIG. 1, main construction of a system with the appearance for performing a method of automatically evaluating physical health state using a game in accordance with the present invention is illustrated, and in FIG. 3, one example construction in accordance with one embodiment of FIG. 2 is illustrated.

The oxygen intake measurement means 55 comprises a spirometer of an oxigen mask shape, measuring maximum oxigen intake and using for evaluating cardiac and pulmonary endurance power.
Meanwhile, the button input device 35 is utilized for examining agility. The examination of agility can be achieved, differently from the general methods, by pressing the button responsive to an event given by presenting abrupt situation on a screen, as shown in FIG. 11, while displaying a game and evaluating physical strength, that is, by being established so that management on the situation is performed. In this case, agility is evaluated by a time difference between an outbreak of the event and the pressing action of the button. Preferably, such situations are presented several times on the game space for evaluating the physical power, and at each time the pressing speed of the user(a response speed against the presented situation) are repeatedly measured, from which error factors(for example, considering maximum/minimum range or constant range) are removed and an average value is obtained.
Furthermore, the load of the exercise equipment 10 is adjusted according to the kind, the level and the proceeding state of the game. The present invention is constructed so that the user may follow a preceding reference person 1 in a templated game, and the load adjustment section 80 comprises a load adjustment apparatus 81 and its load control module 82 so as to adjust load of the pedal according to each different situation(adjustment of inclination, ground surface state, etc.,) given by stages of the protocol to be displayed on a screen. Further, the load adjustment apparatus 81 may consist of a common brake device, or may be constructed diversely such as changing of gears, or inclination of the exercise equipment 10.
Meanwhile, by comprising a smart card reader/writer 41, the present invention can be constructed so as to store user's personal information and the present information of physical strength and health state through his recent measurement result and achieve a continuous administration of the user's information and exercise. First, the personal information is stored through the smart card reader/writer 41, the result just before the present measurement at every measurement is shown, and the change in the physical strength and every physiological variable is written in other memory means 40(other backup device, a hard disk, a ZIP drive, a CD ROM, a database) and administered, thereby enabling to construct the present invention so that an administration of a systematic momentum and an exercise method may be performed.
Furthermore, the image camera 36 may be used for purposes comprising a method showing a screen briefly after storing user's appearance before executing measurement, a method using the stored appearance as information constructing the virtual subject 2 reflecting the user in the game environment, an image chatting in the virtual space connected with a network such as LAN, etc., a service on the network to use a series of image cameras with an internet phone, etc. A speaker can be used at the same time with an image camera, a microphone, etc., for various guidances assisting measurement of the user or an internet phone, an image voice chatting, etc., through the network such as LAN, etc. The microphone can be used for an answer to the questions, etc., voice orders for various actions, an image voice chatting, etc.
In FIG. 4, the whole construction in accordance with one embodiment of a method of the present invention is illustrated as a flow chart, and in FIG. 5, a concrete flow chart for a physical strength evaluation module in FIG. 4 is illustrated. Also, in FIG. 6, a concrete flow chart for a game execution and measurement module in FIG. 5 is illustrated as an example.
In FIG. 4, a method of automatically evaluating physical strength with exercise using the automatic physical strength evaluation and exercise system 100 of the present invention, may mainly comprise the steps of asking basic questions, evaluating physical strength according to measuring protocol, prescribing exercise using the physical strength evaluation, and exercising for promoting health with achieving bio-feedback of various physiological variables after the exercise prescription, in steps S1 to S4.
In step S11 of FIG. 5, the user or the measured person registers as a member and receives a member card. On issuing the member card, various body information such as height, weight, age, girth, etc., is stored in a database 44.
The question of health may comprise steps 1 and 2. The step 1 classifies a healthy person, a diabetic, a hypertensive, a cardiac disorder patient, a muscle and skeleton disorder patient, etc., through basic questions, which are used as materials for removing dangerous factors to be able to occur on the physical strength evaluation and for judging the health state. The step 2 provides with different questions by healthy or various disorder patients, and then detailed classification about the stage of health is performed. That is, by using a classification(man, woman, the old and the weak) obtained from the physical information of a patient inputted in the beginning and a classification item(healthy patient and various disorder patients) divided by the basic questions, physical strength evaluation protocol proper for each individual can be provided, or certain or all measurement of physical strength evaluation can be prohibited for various disorder patients, thereby being able to remove dangerous factors(various factors of danger in life or physical functions) to be able to occur on the physical strength evaluation. Also, there is an effect to be able to induce hospital treatment because a diagnosis of disease can be made by means of relationship among various physiological variables obtained by such information and physical strength evaluation.
The question of health can be made by a method of writing directly on various questionaires or a method of performing various input(by operation of the button input device 35 or a mouse, confirmation by voice, other various kinds of inputting methods) of the user or the patient as to the questions, which are displayed in order or totally on the display device 30(a TFT LCD, a CRT Monitor, etc.) in the present system, or explained by voice.
In the physical strength(physical strength related to health and exercise) evaluation of step S2 in FIG. 4, various questions are made for evaluating basic physical strength evaluation displayed on the screen in step 13 in FIG. 5, and, then various physiological variables will be measured as the following order. That is, measurement of body fat for 10-15 seconds, measurement of blood pressure(at stabilized time), measurement of heart rate(at stabilized time) and measurement of left and right muscular strength, as physical strength and health information which should be measured besides the above questions or is convenient to measure before application of measurement protocol for a game execution and measurement step of step 17 are made in step S14 to S16 in FIG. 5.
In step S17 of FIG. 5, the game execution and measurement step according to the present invention is executed, for instance, for 8 minutes, wherein measurement of the physical strength and health information such as heart rate, oxygen intake, agility, momentary power, muscular endurance power, and cardiac and pulmonary endurance power is made, which should be measured during performing a game reflecting multiple protocols standardized according to measurement requirements. In such protocols of measurement, when a kind and a level of a game is determined in step S31 and images of the virtual subject 2 and/or the reference person 1 are selected in step S32, the determined game is executed in step S33, as shown in FIG. 6 for example. In step S34, the corresponding events for physical strength and health information which should be measured continuously during the game are generated continuously, and then the measuring results are stored and displayed. In the event that the measurement is impossible, up-or-down adjustment in a level of the game can be induced.
In step S35, load of the exercise equipment 10 is adjusted by means of the load control module 82 and the load adjustment apparatus 81 of the load adjustment section 80 according to kinds, levels and proceeding states of the game. In step S36, the exercise speed of the measured person or the user is measured by means of a momentum sensing means 83 such as rpm sensor, etc., and reflected by the virtual subject 2 in the game. In common, the user's momentum can be known from added load and sensed exercise speed. Such momentum sensing means 83 can be included by the load adjustment section 80 and a momentum signal such as the exercise speed, etc., to be sensed can be supplied to the main controller section 20 through the load control module 82. Otherwise, the momentum sensing means 83 can be included by the physical strength and health information sensing section 50 and the momentum signal can also be supplied through the sub-controller 61.
Even in this event, when the user's exercise goes off the range of momentum(speed) proper for the kind, the level and the proceeding state of the game in step S37 above prescribed times since the speed is too fast or slow, it is preferable to induce so as to up-or-down adjust the level of the game.
Then, in step S39, events for physical strength and health information which should be measured one time or several times during the game are generated one time or several times, and then the physical strength and health information is measured, which is stored in the memory means 40 and displayed in: the display device 30. Even in this event, when the measurement is impossible, it is preferable to induce so as to up-or-down adjust the level of the game.
When the events for every measurement are finished by repeating such event generation(step S40), events for physical strength and health information, such as momentary power, etc., which should be measured after finishing the game execution are generated in step S41 and the physical strength and health information is stored and/or displayed after being measured. Then the game is finished after performing finishing exercise, for example, for 1 minute in step S42. In step S18 of FIG. 5, after finishing application of the measurement protocol as above, measurement of blood pressure at recovering time is made, and in step S19, evaluation of physical strength according to measurement protocols as above is performed. In step S20, exercise prescription(corresponding to step S3 in FIG. 4) through the physical strength evaluation is performed, and exercise for promoting health according to automatic exercise prescription can be executed. At this time, as explained in connection with step S4 of FIG. 4, it is preferable that bio-feed back of various physiological variables after the exercise prescription.
As described in the above, the basic physical strength and health evaluation comprises one part achieved using the game to effectively show various protocols obtained by preceding input of physical information and answers to the questions of health, and other part achieved by taking a series of action in the present system according to output means provided in the present system or the output means and various voice guidance. Information about cardiac and pulmonary endurance power(heart rate), agility(pressing of buttons) and momentary power(can be obtained by performing maximum exercise for a short period, for instance, the momentary power=W=0.065=N/T, where load is equal to W=0.065, W is weight, N is the number of rotation, and T is a time taken in performing one rotation of a pedal) can be obtained through the former. Through the latter, information about muscular strength(grasping power), fatness degree(body fat) and cardiac and pulmonary endurance power(can be obtained from blood pressure and heart rate or F=N, where F is average load applied to the exercise equipment 10, and N is the number of rotation of the exercise equipment 10) can be obtained. That is, in the order of physical strength and health evaluation, measurement of body fat, blood pressure at stabilized time, heart rate and muscular power are performed, and then while the user is performing a game containing effectively various protocols to be applied to the measured person or the user for a prescribed time(for instance, 8 minutes), information about heart rate, oxygen intake, agility, momentary power, muscular endurance power, cardiac and pulmonary endurance power can be obtained using the game.
The game may be constructed with various configuration(various stages reflecting various environments, degree of difficulty, etc.) which various protocols can be applied to. The virtual subject 2 to be indicated reflecting the measured person and the reference person 1 to proceed are appeared inside of two or three dimensional space representing in the output means. The present invention is embodied to the bike for removing various measurement danger factors. Change in heart rate on measurement is measured by a method in which three electrodes are attached to the body with simplified three lead type of electrocardiograph or by a method in which hands are in contact with electrodes located at the handle part to measure the grasping power and the body fat.
If physical strength and health evaluation begins, certain measurement which a game is not reflected to is performed, and then, the measured person executes a game which certain protocols for the user are reflected to by the above-mentioned method. If the game begins, the measured person perceives the reference person 1 to proceed at a certain speed and the virtual subject 2 to reflect a state of himself in the output means concurrently, and proceeds the game by rotating the pedal of the system in order to follow the virtual subject inside of the game. During the game proceeding, the speed of the reference person 1 can be given to be constant, but, diverse load environment is provided for the measured person by adjusting load of the pedal according to various game environments(various environmental changes to be able to expect an increase of load such as a rising hill, a sand road, etc.,) representing various protocols. Further, each speed of the measured person to be changed continuously during measurement and each load at certain points can be used in calculation of work made during the whole measurement and calculation of other various measurement. That is, the measured person rotates the pedal fast or slow according to the game, thereby increasing or decreasing the speed of the virtual subject 2 to reflect himself in the game by reflecting the pedal ratation speed. The agility is evaluated by calculating response time using a time difference between an outbreak of the event and an input of the measured person where the particular event is presented and the measured person takes one of various input types for solving this event when the game is executed for prescribed time. It is preferable to repeat such similar events and to obtain an average value
In FIG. 8, construction for explaining the process of exercise prescription in FIG. 4 is shown.
Through the basic questions, the degree of the physical strength and health evaluation can be determined. In the case it is difficult to evaluate the physical strength and health because the measured person suffer from sever disease, the danger factors can be prevented beforehand. In the physical strength and health evaluation, men, women and the old and the weak are classified, and different protocol is applied, in which gradual increase and decrease of load per the total time is applied differently. When the physical strength and health evaluation is finished, measured physiological variables are analyzed synthetically, and a synthetical physical strength and ability index, an exercise-related physical strength index, a health-related physical strength index, etc., are presented with being classified into 15 stages. Also, health age related to these is presented and analysis opinion is made. By doing as above, it is possible to analyze automatically by means of objectified materials through an application of analysis template for the physical strength and health evaluation.
In the exercise prescription, by analyzing the measured physiological variables synthetically after the physical strength and health evaluation is performed, a synthetical physical strength and ability index, an exercise-related physical strength index, and a health-related physical strength index are presented with being classified into multiple stages. Also, health age related to these and analysis opinion are presented on the output means or in a output form. As shown in FIG. 8, the exercise prescription is performed according to the following flow after evaluating the physical information of the measured person, question examination materials and the various physiological variables obtained through the game synthetically, and is calssified into, for instance, a health group, a danger group, a disease group and an exercise-prohibition group.
In this event, the exercise prescription proper according to each classified group is made. Presented exercise prescription is general exercise(walking, jogging, running, swimming, etc.), exercise using general health apparatus(a running machine, a health bike, various muscle power advance apparatus, etc.), and/or games using the system in accordance with the present invention. The game may be a series of template type game predetermined according to the various exercise prescription for the measured person, said game being in a single game type or a complex game type. The game to be applied according to the exercise prescription is discriminated in the present system and provided, or taken in the form of reflecting sports or game elements which the user prefers. The game may be executed according to the fixed exercise prescription or may be provided in the form of being able to remove dangerous factors capable of occurring during exercising by reflecting change of the various physiological variables(heart rate and its chage, maximum oxygen intake, etc.) fed back continuously through the game.
Health promotion exercise can be arranged using the system of the present invention according to each exercise prescription related to fatness, strengthening of cardiac and pulmonary capability, strengthening of muscle and articulation function, and promotion of growth with basic exercise(walking, running, bicycle, etc.). Such health promotion exercise step can also be performed by raising the level of the reference person 1 in the game, and moreover by presenting a competitor in the game using a network.
In FIG. 9, construction for embodying one method in accordance with the present invention using a network is illustrated as a block diagram.
With such construction of the network, a health adminstration server 90 can also provide each individual health adminstration service, and in this event, each client comprises the automatic physical strength evaluation and exercise system 100 and a connecting means. The health adminstration server 90 is preferably constructed so as to build up and utilize a database for each member by means of a separate memory means 91. A database management server may also be comprised. By such constructions, it is possible to transmit the physical strength and health information from the automatic physical strength evaluation and exercise system 100 to the health adminstration server 90, and receive the physical strength and health evaluation information and the exercise prescription information from the health adminstration server 90 in the automatic physical strength evaluation and exercise system 100. In addition, each data, update programs, etc., can be provided.
