Technical field
The present invention relates generally to the analysis of foot measurement and foot measurement data.
Background technology
Many people need foodcare product.Foodcare product can be placed on footwear inside to provide support, cushion, to improve fitness or comfortableness etc.The example of foodcare product comprises orthopedic product (hereinafter referred to as " orthosis (orthotics) "), shoe pad, foot pad, heel cup (heel cup) etc.The example of footwear comprises sport shoes, walking shoes, dress shoes, high-heel shoes etc.
Foodcare product can be obtained by two kinds of different modes at present, that is, as the narrow foodcare product that manufactures in advance can bought from the retail display in shop and as indivedual customization foodcare product making particular requirement to mate client.
But these the two kinds of modes buying foodcare product run into many problems.
When the foodcare product manufactured in advance, although packaging can provide certain to instruct, client is possible must guess which product is suitable, the size of such as client, foot characteristic and other attribute.But certain product on probation even if client has an opportunity, client may not know support or the size of the best type of the foodcare product of the particular foot characteristic for them yet.This convention may cause client to buy multiple product before finally finding the product meeting customer need.Therefore, retailer wishes that service can be provided to help client selects correct product, and without the need to employing through specialized training and/or the personnel understanding all possible product, foodcare or footwear and foot type.
When customizing foodcare product, needing considerable expertise and time to measure the foot of client, determining required foodcare product, and manufacture the foodcare product of the foot specification of mating client.Therefore, foodcare product is customized usually more expensive than the foodcare product manufactured in advance.In addition, creating customization foodcare product generally needs trained professional to measure client and make or subscribe foodcare product.
Therefore, need to be used for measuring the foot of people to help equipment and the automatic technology selecting foodcare product or automatically select foodcare product.
But, when the present inventor has been found that and realizes this equipment/technology, there is many technical problems.Such as, equipment must be low cost, reliable and use simple.In addition:
(1) before the foot of people is measured, importantly guarantee that this person correctly stands for the type of used measuring transducer, otherwise measure may be inaccurate and be variable.
(2) even if someone correctly stands, also may occur inaccurate when foot measurement, therefore equipment/automatic technology should identify and solve the reason of these errors.
(3) a kind of measurement carried out the foot of people is usually needed to be measuring of arch of foot.But, occur about how being used in sensor that two dimensional surface carries out measuring, if two-dimensional pressure sensor is to measure the problem of this three-dimensional feature.
(4) for the foodcare product of some type, need to carry out kinetic measurement (that is, the measurement of gait that carry out when this person walks, that such as analyze this person) to the foot of people.Therefore, the equipment that can carry out such measurement is needed.But this equipment must not take large volume, otherwise it can occupy the space of planes too much in shop.
(5) quantity of the dissimilar and size of foodcare product is very large, therefore needs to carry out as client selects the number of times of the foot measurement of product also very large.Therefore, need to reduce the pendulous frequency that will carry out, the equipment/automatic technology thus reducing Measuring Time and inaccurate probability.
Consider these technical problems and propose the present invention.
Summary of the invention
In order to solve the problem (1), the invention provides and wherein use the foot of the people on multiple pressure transducer effects on surface to carry out tonometric equipment and method.Process the signal from pressure transducer, to be the force (point of force) (being preferably the body weight that the comprises this person center by the force of the point on its surface of working) on this person's gauging surface, and this force of this person and the target area previously determined on the surface are compared, for the Measurement accuracy using sensor.The display position in current force of this person and the display of the difference of target area is presented, to help user to move (therefore changing the point that its body weight is worked by it) and to make its target approach district, force to user.Before the force of this person is within target area, its foot is not measured.

At the end of retail kiosk uses, or before using by day, manager 110 can initiate to check, or alternatively, self-inspection can be initiated in retail kiosk.Self-inspection can comprise pressure pad situation inspection (do not have to sense sheet during load and lost efficacy (misfiring)), the inspection of processes sensor (handle-sensor), process computer (handle-computer), touch screen inspection, system storage cleaning, base measuring pressure pad, calibration scale, consider the summer time etc.
Before startup retail kiosk, or when retail kiosk does not use, the output device 102 that manager 110 can use input equipment 103 or such as touch screen interface etc. can serve as input visits processor 104.Or if there is mistake when retail kiosk just uses, then this mistake can point out manager 110 to take action.Manager can arrange the parameter for error checking and correction, such as weight range restriction, Computational biomechanics data estimation or select the equation coefficients of foodcare product.Manager also can download from network 107 or upload new product list, stock 117, video clipping, language template etc. to storage device 105.
Fig. 2 illustrates some example foot sizings.The foot sizing that example is estimated can calculate according to the pressure measxurement undertaken by foregoing example retail kiosk.Foot sizing can be the ordinate 200 extending to the transverse center of the second toe from the transverse center of heel.Foot length 201 can be the point that namely the rearmost point 204(of foot on this ordinate on foot pressure figure approaches heel) and the First Point 213(i.e. point approaching toe farthest) between distance.Foot breadth 202 can be the projection of the distance between the inner side point 206 of foot pressure figure and outermost points 207, and the projection foot breadth shown in figure is vertical with ordinate 200.Foot arch index is the estimation that can be used for characterizing arch of foot.Foot arch index may be defined as without toe footmark middle one-third of the area be called the total without toe footmark area ratio of sufficient body (foot body).The division of three sections is carried out along lines L 205, draws between the transverse center 212 of the heel on the horizontal line of the transverse center point 211 of second toe of these lines on the horizontal line of toe line (toe line) 203 and the rearmost point 204 of heel.Therefore, foot is divided into A 208, B 209 and C 210 three equal parts, and each 1/3rd is that length L is divided by 3.Foot arch index equals the area ratio of B/ (A+B+C), and it equals the area of B divided by sufficient bulk area.Be appreciated that foot sizing can use alternative approach or estimate according to alternative measurement point.
Fig. 3 a illustrates the example of the position of the alignment mark shown on pressure pad.When people stands on pressure pad, its foot should be positioned at the approximate angle of two foot-shape profiles 311.Alignment border 310 labelling can receive the rear farthest border of measurement.In inside, sensor array grid can detect the feature of foot.As long as certain part of measured zone can be obtained, then can determine whether measured stands in outside examination network.This person is then indicated how to move its foot, to be within measured zone.Such as, determine that a kind of mode of foot whether within measured zone determines whether whether a part for foot is in the side of examination network, such as, can measure on the sensor grid of examination network outside.Therefore, examination network 312 definable is within larger real sensor grid 313 array boundary.If sensor detects the measurement within 312 and within 313 of that same area, then understand systematicly, foot is in border outer, and instructs this person to adjust its foot.
Fig. 3 b illustrates the measurement that can draw from the pressure measxurement pressure pad.Determining that in this alternative approach of aliging, people can stand within the appointed area as in Fig. 3 a.Ordinate 307 can be calculated, to provide the expectation of the position of the lines connecting the center 305 of heel and the center 306 of second toe.The profile 308 of foot can be make people put sufficient roughly can Measured Boundary.Profile can be large enough to be enough to applicable most people.Such as, in one embodiment, can be toe to provide slightly larger than 6 inches.Grid 309 can be provided to provide even measuring unit, and can (but not necessarily) they are supplied to the people standing on pressure pad.
The width of profile 308 specifies three alignment mark X 301, Y 302 and Z 303.Alignment mark X 301 is multiplied by average first metatarsal length draws with the ratio of average first toe length by getting 100%.Average length is suitable for the grouping of the people based on race, sex, foot type or total crowd average foot length by research draws.Alignment mark Z 303 is multiplied by average fifth metatarsal bone length deducts predetermined cell number to draw with the ratio of average 5th toe length by getting 100%.Alignment mark Y 302 draws by getting longitudinal average length difference between second and first metatarsal head.General hyperbolic fit curve can be drawn, to represent toe line 304 on three points.Be appreciated that average length can have certain change, therefore the accurate location of alignment mark may slightly deviation.
In one embodiment, alignment mark X 301 can be estimated as 73% (=100% × 19.29/26.32-38 grid of pressure pad length; 19.29=average Canadian first metatarsal length; 26.32=average Canadian first toe is long).Alignment mark Z 303 can be estimated as 64% (=100% × 16.9/21.69 of pressure pad length; 16.9=average Canadian fifth metatarsal bone length; The average Canadian of 21.69=the 5th toe is long).Each grid can equal 6.73 mm.A longitudinal average length difference between second and first metatarsal head is 3.4 mm, and another meansigma methods is 3.2 mm.Get the average of two meansigma methodss and will draw meansigma methods 3.35 mm.Assumed average foot length is 26.32 cm, then second metatarsal bone head position position can on move 4.45 mm (=3.35 × 35/26.32).If each grid equals 6.73 mm, then the position-movable single grid of alignment mark Y 302 distance about 2/3.The position at the center 305 of heel and the center 306 of second toe can draw from meansigma methods, but in this example embodiment, it is defined as between the 9th and the tenth grid of transverse direction.
Fig. 4 illustrates according to one example embodiment, for characterizing the foot of people according to pressure measxurement and selecting the flow chart of instantiation procedure of the foodcare product recommended.Instantiation procedure realizes by retail kiosk, example retail kiosk as shown in Figure 1.400, instantiation procedure can be initiated by manager.401, output device can show the screen of attractability, as at the picture of the commodity viewing area product sold in example retail kiosk, and waited for the input (402) of people.When not inputting, the screen of attractability can continue display foodcare product (401) or other image to arouse people's attention.In an alternative embodiment, distributing mechanism (dispensing mechanism) can replace commodity viewing area, and distributing mechanism automatically or can start the process of distributing the foodcare product recommended according to the request of people.The Voice & Video segment of interval can with the display of foodcare product.
When someone such as by touch touch screen or press start button respond the screen of attractability time, it can be available (403) that process can indicate various choice of language, such as English or Spanish.This person can indicate language preference, and error checking and correction can be performed (404).When carrying out pressure measxurement, when the foot of people is grouped in classification group, or when the foodcare product recommended is by selection, various screen can be shown.Each at these screens, mistake may occur, or user may spontaneously stop this process.Such as by storing in the storage device of retail kiosk or sending to follow the tracks of at server 106 via network, the corresponding screen of these mistakes or termination and its appearance can be tracked.If there is mistake or termination, then this process can restart (405), and turns back to its standby mode by display foodcare product (401).
If do not gone wrong 403, then 406, this process can idsplay order or show more detailed instruction again.If foot is not yet put on pressure pad by this person, then can do like this.407, display can provide feedback to someone, such as, present the real-time display of the tonogram of the foot of this person.408, someone can be indicated such as to use alignment mark as shown in Figure 3 b to the biped that aligns.The alignment mark of coupling accurate pressure figure position can be shown.Alignment mark can comprise left foot and right sufficient toe line and ordinate, and illustrates by different chromatic zoneses.Automatically the center of heel and the center of second toe can be detected.If no, then can show ordinate, and adjustment foot of must asking for help, until foot aligns with ordinate.Alternatively, as shown in Figure 3 a, user can be pointed out mobile biped in the border that pressure transducer detects.Retail kiosk can determine that whether the biped that whether foot exceeds the boundary of pressure pad, whether the body weight of people exceeds preset range or people is barefoot.409, when someone can be checked to stand on pressure pad, whether light foot.
410, multiple error checking and correction can be performed.According to previous determination, if problem may not solve, then labelling mistake.These mistakes can comprise: (1) is if None-identified someone stands on (even if this person is such) on pressure pad just barefoot; (2) if this person is just standing in outside the boundary of pressure pad; (3) if this person's biped is unjustified; Or (4) if the body weight of this person is not placed on pressure pad equably.In addition, other error checking and correction can be determined.Such as, the minimum and maximum restriction of the body weight of people can be determined.The body weight that must ask for help is between 70 and 400 pounds.Be appreciated that weight range can change, and represent by other tolerance.Due to mistake, this process can attempt again idsplay order (406), to help this person's any problems.This process may arrive the threshold value wherein may not easily dealt with problems, and thus restarts whole process (405).
If be free from mistakes, then this process proceeds to 411.411, obtain the measurement of foot, such as, from the pressure measxurement of the array of pressure transducer.In whole measuring process, measured is such as by leaving pressure pad to stop this process.If such as had problems because of user's its body weight mobile unevenly in measuring process, then also can stop this process.412, any measurement mistake or termination can be detected.If problem cannot solve, then this process can restart (405).413, estimate according to pressure measxurement and biomechanical data, people can be grouped in classification group.414, according to decision matrix or be mapped as this person select recommend foodcare product.Such as, product can be selected according to the physical characteristics behaviour of such as foot arch index or foot length etc.
In one embodiment, foodcare product can be the orthosis manufactured in advance.In an alternative embodiment, processor or pressure transducer can be configured to collect pressure measxurement, such as, to select another kind of foodcare product, heel cups, pressure pad etc.Identical pressure measxurement can realize in for the selection of dissimilar foodcare product and recommendation process.But, alternative point can be got from pressure pad, to recommend dissimilar foodcare product.Such as, although identical pressure measxurement can be used for recommending orthosis and heel cups, the alternative point concentrating on the measurement of heel can determine heel cups fitness more accurately.Can use two kinds of methods, and processor and pressure transducer only need to be configured to adaptation two kinds of foodcare products.
Alternatively, 414, can be someone and select multiple foodcare product, so that from wherein choosing.This person also can be pointed out to answer the problem providing additional information, such as, parameter can be adjusted to search for the accurate factor of more accurate match for this process provides.The type of the activity that this kind of accurate factor can use preference, this person often participates in, foodcare product can be mated the type of the footwear of use, the sex etc. of this person, to reduce selected orthotic list further.Can this process early stage, such as before carrying out pressure measxurement, inquire alternative question.The foodcare product of recommendation can be changed into another kind from the foodcare product of a type by the alternative factor, and such as orthosis is to heel cups.
415, such as can to the information using the people in above-mentioned retail kiosk to show several types.Can the labelling of model of foodcare product recommended of explicit identification.These labellings can help people to search to be positioned at the corresponding foodcare product of commodity viewing area.In addition, the real-time pressure may checked together with people is measured, can peak value display tonogram, to present the pressure measxurement carried out in retail kiosk.Also can indication example as any one relevant information estimated with biomechanical data of the body weight, foot type etc. estimated.The example that displayable biomechanical data is estimated comprises the cross point of the profile of foot length, foot breadth, body weight, foot arch index, toe line and foot, ordinate (drawing on surge pressure figure) or ordinate and sufficient body (namely not comprising the foot area of toe).
416, after someone has completed measurement and has received the information relevant with the foodcare product recommended, this person can select to restart this process, or this person can leave measuring device, this will restart this process automatically 401, to show foodcare product, wait for that new people initiates this process simultaneously.
If the example retail kiosk with Fig. 1 with the use of this process, then can be stored or be sent by network and conclude the business relevant value in performed retail kiosk by someone.The example of storable retail kiosk Transaction Information be used the number of times in retail kiosk, use system has come to select the number of times of foodcare product to someone, whether someone stops to use retail kiosk and this person just checking which screen when stopping, recommending the counting of which product and use the grand total of the people in retail kiosk and use the date-time in retail kiosk and time span that everyone uses retail kiosk to spend.If if retail kiosk not to be activated or retail kiosk is arranged to and only works at some date-time in the quite a while, then can measure last people, and 417, retail kiosk can automatic shutdown or transfer dormancy to.
If not barefoot, then the measurement of the foot of people significantly changes.Therefore, the process automatically detecting footwear and whether worn by the people that its foot is just measured can be provided.Fig. 5 illustrates the example pressure figure that foot sizing is shown according to one example embodiment, and it can be used for determining whether the foot on sensor is barefoot.Tonogram is generated after can collecting static pressure in stipulated time section, as 2 seconds.On tonogram, ordinate 500 connects the transverse center 502 of heel and the transverse center 501 of second toe.The center of heel and the center (and other concerned point any) of second toe are determined by the foot profile of measurement and general foot template being compared.Vague generalization foot template creates by the sample or average many foot type getting actual measurement.According to tonogram, the geometric center of foot can be determined.General foot template can expand according to the size of foot or length or reduce, and can use that geometric center is as a reference point to be compared general foot template and tonogram profile.Then, as the matching process of best fit can be used for determining the most suitable foot template.Use the most suitable general foot template, other points all of foot can be estimated, comprise the center of heel and the center of second toe.
Illustrate with being convenient to for clarity, in Fig. 5, the First Point along ordinate is projected out as the last dotted line 503 vertical with ordinate and First Point line 504 with rearmost point.The projection of the lines between rearmost point and First Point is foot length (FL) lines 505, and it equals the distance between rearmost point and First Point.Mark is along three points measured by the relative foot length of ordinate.These are some C 508 measured by 75% of the 16% point A 506 measured, the 50% point B 507 measured from the FL line 505 of rear end of FL line 505 from rear end and the FL line from rear end.Be appreciated that these points can change, and these points can show from the trial run of the foot for about 30 tested objects.
Lines A 509 is vertical with ordinate, and is drawn by an A 506.Lines A 509 is crossing with the border of tonogram, and the length of lines A 509 can intercept in the profile of tonogram.The profile of tonogram indicates during real-time pressure is measured the outmost pressure spot reflected.The length of lines A 509 represents heel width (HW).Lines B 510 is vertical with ordinate, and is drawn by a B 507.Lines B 510 is crossing with the border of tonogram in midfoot area, and length intercepts in the profile of tonogram.The length of lines B 510 represents the estimation of arch width (AW).Lines C 511 is vertical with ordinate, and is drawn by a C 508.The widest point between lines B 510 with lines C 511 projects on inner side 512 and outside 513 as the lines parallel with foot.The Breadth Maximum of the tonogram between lines B 510 and lines C 511, distance namely between lines 512 and 513 represent the estimation of forefoot width (FW).
Fig. 6 illustrates according to one example embodiment, use foot sizing from Fig. 5 to determine the instantiation procedure of barefoot foot whether on pressure pad.600, tonogram can generate when detecting barefoot and starting.As previously described, tonogram is generated by collecting static pressure in stipulated time section.601, mark ordinate 500.602, mark key point, is specially an A 506, some B 507 and some C 508.603, can determine estimate heel width, as in Fig. 5 relative to drawing as described in lines A 509.604, can determine estimate arch width, as in Fig. 5 relative to drawing as described in lines B 510.605, if not crossing with tonogram, then 607, arch width is endowed predetermined value, certain such as non-vanishing constant, to avoid the situation that numerical value may be removed by zero.If arch width has value really, then 606, arch width is endowed that value.608, can forefoot width be determined, as in Fig. 5 relative to drawing as described in lines C 511.609, the value of precedence record and predetermined value are compared.By recording and comparing the value of the actual tested object wearing footwear and compared in they and measurement when standing barefoot, draw predetermined value.For biped, example condition is:
In this illustration, FL_low=3.5; FL_hight=6.0; FW_limit=1.2; AW_limit=0.1.
610, after determining condition, if condition " establishment ", then 611, this person is identified as barefoot.If condition is false, then 612, user is identified as and wears footwear.Be appreciated that and value can be added condition and range, determine whether people wears the option of socks to have.Determine that the process of barefoot foot whether on pressure transducer terminates 613.
By ratio and actual tested object being compared, and calculating these ratios and whether constant mates with the ratio for those tested objects on an average, drawing target rate and constant value.But, by adjusting the point of lines A 509, lines B 510 or lines C 511 on intensity of variation along foot length line, also can ratio be changed.The position of these change lines draws by testing multiple object and calculating the scope with minimum error.Alternative measurement can allow break or in fact increase other lines.Such as, lines D can add between lines A 509 and lines B.The ratio that lines D and other width are compared with length also can create the new constant compared with ratio.This new constant can be when with lines D to length, width, arch width, certain other newly show that the ratio of the measurement of lines etc. compares time bottom line (or minima) or maximum (or maximum constant).
Fig. 7 illustrates according to one example embodiment, carry out pressure measxurement so that the instantiation procedure estimated of calculated example biomechanical data as shown in Figure 2 etc.700, this process can start after the foot of people is on pressure measurement sensor.When starting, other verification various also can be performed, to carry out alternately with measured.Such as, when people sets foot on pressure pad, output can show real-time pressure figure immediately; Someone can be pointed out to take off one's shoes and set foot on pressure pad in the appointed area of pressure pad, its body weight balances between left and right, front and back simultaneously; This person can be pointed out such as to be indicated by click START button whether prepare to measure.Some error checking and corrections can perform in pressure measxurement acquisition time, such as, to determine in fact whether barefoot foot be on sensor or determine whether there is other mistake of foot alignment, body weight etc. as in 408 or 410 of Fig. 4 as in figure 6.
701, definable target area.Target area can be the geometric center of the pressure print of biped, but also can be another geometry pressure reference point.When determining target area, target area distad can offset 10%, to force user slightly to lean forward, thus allows the toe of this person directly to contact with pressure pad.702, the centre of force (COF) that someone can be pointed out to make this person matches in target area.By calculating the moment of torsion of each sensor points and getting by the barycenter of the power institute weighting of each point so that the entirety creating the amplitude of various power and the power of position represents, determine the centre of force.The centre of force can be used for the center of gravity indicating human body.
703, if the length variations of foot pressure figure is poor more than 15 mm, i.e. about 2 sensing piece elements, then 701 repeat, and target area can recalculate and show to this person at output device.The length of the tonogram the recalculated change of trigger definition target area can be depending on the use of measurement.15 mm threshold values are approximately 2 footwear sizes, and provable recalculating is rational.This person can be pointed out to continue to make the COF of this person to match in new target area.If 703, there is not the obvious increase of foot pressure length, then initial target district can not recalculate.704, final goal district can be positioned at fixed position, unless this person moves or lift his foot.In an alternative embodiment, target area also dynamic is determined, wherein COF mates dynamic object district, and it may be defined as regional center.
705, static pressure can be initiated and measure.Frame can be collected by different rates.Pressure data can the speed of 10 frames per second be collected.When getting frame, target area can show on an output device.706, the frame of pressure data can be collected.According to tonometric anticipate accuracy, the frame of minimum number can be needed, such as 20 frame pressure datas.20 frame pressure datas of 10 frames per second can need people that target area is kept 2 seconds.
Among collected frame, a part for frame may be very poor.By evaluation process, some frames are got rid of use.Evaluation process can use any amount of distinct methods.Such as, Fig. 6 is shown for determining whether that barefoot method also can be used for determining whether frame is qualified frame.If determine it is barefoot, then frame is qualified.If this frame is not assessed as barefoot, then probably collected frame is very poor, or there is mistake and be thus eliminated.Another exemplary method can be determine whether the balance of the body weight between front and rear and side suitably distributes according to COF.
707, according to carried out pressure measxurement, static foot profile (SFO) can draw from pressure measxurement.708, after carrying out static pressure measurement, can notify that this person has completed static pressure and measured.
709, Quasi dynamic pressure measuring service can start.In general, during walking, carry out kinetic measurement, to determine the pressure of its various piece according to the gait of people.But, Quasi dynamic process estimate the pressure created type and without the need to walking.Or rather, Quasi dynamic process can allow to carry out pressure measxurement when someone's stands on one foot, so that producible pressure during simulating walking.
710, this person can be pointed out such as by holding the gimbal lever to keep balance or keeping balance on one's own account, then while maintenance balance, slowly lift a foot lightly and stand with the first upright foot.711, part the first upright sufficient target area can be defined according to previous at 707 determined static foot profiles.A few modifications can be carried out according to monopodia tonogram in the position of target area.User can be pointed out to mate the target area of the first upright foot.
712, the feature mechanical state of people can be monitored, and the difference that can realize the collection of pressure frame triggers.Such as, the triggering starting to collect pressure frame can be when COF target approach district and when stablizing predefined short time period (as one second).The frame of variable number can be collected equally; Such as can collect 20 frames at 10 frames per second.An alternative triggering can be collect frame when the load on upright foot reaches 90% body weight.Be appreciated that change and the combination of feature mechanical state can the collections of trigger frame.Such as, when the COF of people mates target area and when obtaining at least 95% of static body weight, can trigger frame collect.713, once measurement collection completes, then can the foot of raising be put back on pressure pad assignor.
714, if measure biped respectively, then can calculating parameter 715.If no, then 710 to 713 can repeat, to collect the frame of the second upright foot.The order that each sufficient frame is collected can change.Take turns in 710 second, when the upright foot of measurement second, SFO may need to rotate, to mate the pressure print of the second upright foot.711, also new target area can be defined according to SFO.A few modifications also can be carried out according to monopodia tonogram in position.
715, according to from the static state of collected frame or Quasi dynamic pressure measxurement, Foot biomechanics data estimation can be calculated.Only has qualified frame just for Computational biomechanics data estimation.Determine that the step of qualified frame can comprise foregoing method, such as, use and determine whether barefoot method.Evaluation process is generally in the execution of coming performing biomechanical data estimation calculating, if because frame is dropped in evaluation process in the con-trary case, then process will be wasted.But the order that Evaluation and calculation biomechanical data is estimated can change.Such as, assessment can be carried out for all frames, and the calculating that then biomechanical data is estimated can be carried out for all the other frames, and vice versa.Alternatively, the combination of the calculating of evaluation process and biomechanical data estimation once can be carried out for every frame.
Use Fig. 2 as the reference of Computational biomechanics data estimation, foot length 201 is by carrying out searching for along the longitudinal axis and determining that minimum and peak is determined.Distance between the rearmost point 204 of heel and First Point 213 can be calculated as foot length 201.General foot profile can be used for matching pressure figure, similar to the method shown in Fig. 5.The transverse center point 211 of second toe and the transverse center 212 of heel can draw from foot template, and the ordinate of lines between can drawing as two points.Ordinate becomes the axle of the direction of search.Use tonogram, toe line 203 is determined by the peak value and valley searching for pressure.Such as, halluces is known as the large peak value with pressure, and the valley of pressure is present between toe.Distance between the rearmost point 204 of toe line 203 and heel is the distance of lines L 205.The gross area of the foot within the lines L of foot is sufficient body, is made up of the area sum of part A 208, B 209 and C 210.According to the position of pressure, the area of A 208, B 209 and C210 can be calculated.Foot arch index equals the area of B divided by sufficient body.The foot arch index of the foot of people can be then the average foot arch index for each sufficient all qualified frame.
Biomechanical data is estimated to comprise foot sizing, the foot type of estimation and the body weight of estimation.Such as, computable biomechanical data estimate to comprise static and Quasi dynamic pressure surge pressure figure, measure from combining left sufficient and right sufficient Quasi dynamic foot pressure the artificial biped surge pressure figure, foot length, foot breadth, body weight, ordinate, foot arch index etc. that draw.Biomechanical data is estimated can be stored in memory block, retail kiosk or be sent to store by network.Demographics's information, such as relevant to the foodcare product associating customer identification number that corresponding biomechanical data estimates and recommendation information can store in the storage device or by forwarded to be stored in central database or server.
Fig. 8 a illustrates example decision matrix according to one example embodiment.Decision matrix module is used for classification group is relevant to foodcare product type.Decision-making can part from can various foodcare products draw, and thus can to change according to the product specification list stored in memory block.Classification group can based on biomechanical data estimation or directly based on pressure measxurement itself.Another example of selection foodcare product is the mapping between classification group and foodcare product.
One group of 14 orthosis manufactured in advance can be provided, name as submitted to is simultaneously called described in the U. S. application 11/524979 of the application of " Cushioned Orthotic ", JIUYUE in 2006 submission on the 21st, it transfers the assignee Schering-Plough Healthcare Products of the application, Inc..These orthosiss comprise 4 length/sizes, the arch support of 2 different brackets and the buffering of 2 different brackets.But, maximum size is only provided to the buffering of a grade.This may be because the people of maximum size foot needs maximum buffering.
Particular matrix in Fig. 8 a is divided into scope and carrys out index according to the body weight of people and foot arch index.The foot length of these Range Representations this person.Such as, there are four scopes: for being less than the scope A 850 of the foot length of 244 mm in example matrix, for being greater than and comprising 244 but be less than the scope B of the foot length of 255 mm, for being greater than 255 mm but being less than the scope C of the foot length of 270 mm, and for being greater than and equaling the scope D of the foot length of 270 mm.Each scope comprises the cross reference between body weight and foot arch index.
In example matrix, between under-weight and high body weight, divide body weight, but along with more products model and body weight tested, the body weight kind in scope can increase.Division body weight between under-weight and high body weight is medium body weight.The medium body weight for the people of specific foot length is estimated in the determination of medium body weight.For having certain foot length but the people heavier than the medium body weight of that foot length, the type of support can need larger buffering.Therefore, medium body focuses between different range and changes.Along with foot length increases, estimate that medium body weight also can increase.
In example matrix, low, medium or divide foot arch index between standard and height, but for more products model, the kind of foot arch index can increase.Low foot arch index scope 853 may be defined as and is greater than 0.257.Medium foot arch index scope 859 can be greater than 0.173 and be less than or equal to 0.257.High arches index range 860 can be less than or equal to 0.173.In these examples, there is inverse relationship between foot arch index and arch of foot, such as foot arch index is higher, then arch of foot is lower.Right foot and left foot likely foodcare product sold separately for left foot and right foot, because likely will have different foot arch indexes.Assuming that foot length and body weight constant.If foodcare product is only sold in pairs, then low or high arches index will be better than medium/standard foot arch index.Such as, if right foot is high arches index and left foot is standard foot arch index, then selected model will for high arches index.Between high arches index and low foot arch index, more conservative product can be selected, such as, can select medium foot arch index.
The foot length of end user, foot arch index and body weight, product type can be selected and be recommended that people.Such as, if the foot length of someone be 220 mm, body weight be 120 pounds and foot arch index is 0.261.The length of 220 mm represents that this person falls into scope A 850.Scope A 850 has the medium body weight 855 of 135 pounds, and therefore the people of body weight 120 pounds will be categorized into under-weight 851.This person is put into the low arch of foot 854 of scope A by the foot arch index of 0.261.Low arch of foot 854 within the scope A 850 of under-weight 851 will recommend " product 1 " 856.As another example, assuming that the foot length of someone be 220 mm, body weight be 150 pounds and foot arch index is 0.205.As previously mentioned, foot length will fall into scope A 850.Scope A 850 has the medium body weight 855 of 135 pounds, and therefore the people of 150 pounds will be categorized into high body weight 852.This person is put into the medium i.e. standard arch of foot 858 of scope A by the foot arch index of 0.205.Medium arch of foot 858 within the scope A 850 of high body weight 852 will recommend " product 4 " 857.
