Description

Interactive printed material and sensor device

Technical field

The present invention relates to interactive printed material and sensor device.

Background technology

Printed material is used for various purposes traditionally, especially comprises aims of education and entertainment purposes.The usual manner of understanding printed material is to watch it simply and analyze the image that forms on the retina.Then what the brain sensing seen and for example identified that image is pure picture or for example comprises symbol, and if latter event, and brain is attempted to decode and comprehend these symbols by speech or mathematical expression.By utilizing printed material, there is the people of eyesight extensively to distinguish a large amount of information for countless purposes.But, this information translation mechanism be only limited to can set up on the image and human eye can debate other information.

In recent decades, having understood printed material can carry the unconspicuous out of Memory of human eye.The suggestion that various printing need utilize the information of utility appliance identification has been proposed.Thus, for example, a kind of standard method that prevents that article are forged (can find forgery when perhaps occur forging at least) is to print the relevant printing mark that for example it just can be found out when with the UV-irradiation thing, for example on bank note.Although but a kind of diverse ways is to stamp can find out thing hard to understand, thereby the onlooker can not understand.Typical example is the bar code of printing: condition code preferably can be used as black and white bar legend to be seen, these size and arrangement (and usually with alphanumeric) can make the onlooker know that it is a bar code, and be more but in addition the onlooker does not know.But bar code reader can extract signal and utilize suitable programming for example to become this conversion of signals sign to have the signal of the specific products of this bar code from these.

This shows and can be configured to provide the more information of seeing than the onlooker printed material under following two kinds of different modes: it can comprise the information that eyes are not seen, but perhaps it can comprise the information that appreciable onlooker does not understand or is ignorant of.

In the printed material field of education or entertainment purposes, propose such printing technology and produced the commercial product of the success that is just putting goods on the market in some cases, and the some data in the generation patent documentation.For example, WO 93/17407, US-A-6089943 and the GB-A-2359402 user that openly comprises printed material and certain form can be used to and the educational system of the bar code reader that this printed material is mutual.

The another kind of method that has proposed is to print so-called " pattern indicator ", and visually but it is very little can picks up by suitable sensor unit.US-A-2003/0133164 discloses this system.The characteristic that a kind of human eye of printing on the substrate is not seen is a conductance.US-A-3818610, US-A-4183152 and US-A-4868374 openly rely on " sensor pen " and suitable mutual education or the amusement appliance between the printed material on the substrate (can normal paper), wherein are held by the user and this printing is optionally in the electrically conductive ink mode.GB-A-2370349 and it be equal to product WO 02/50802 open another kind of be the modification of form from question-and-answer game, wherein the user has one and is comprising the pen that can debate the sensor of other printing ink fluorescent characteristic.

The system that depends on electrically conductive ink and/or depend on the printing ink that contains special fluorescent component is not especially flexibly, and under any circumstance needs specialty inks, thereby this sometimes then require special printing technology undesirably to improve the cost of producing printing material.

The patent specification WO-A-83/02842 that has announced discloses a kind of interactive printing material/sensing system, its utilize invisible printing but can be by the information of sensor.Particularly, this instructions discloses a kind of system that utilizes human eye can not work and invisibly printing be encoded on infrared wavelength.According to seeming very differently this fact of reflects infrared light of type that identical black printing (or four looks are handled printing) depends on " black material " that use in the employed printing ink, can reach difference and visually seem identical zone.

This technology can be used to provide various teaching and entertainment systems in the reality, and this system comprises a sensor element and a printed paper or a book, and wherein this sensor element is configured to be held in the shape of " pen " or " rod " in user's the hand usually.The for example removable vernier of other shape of this sensor or " mouse " also propose.This sensor element comprises the infrared transmitter of certain form, if this sensor element is usually located at an end for long " pen ", and comprises suitable electronic circuit and is the power supply of form with the baby battery.

Usually disposing with this electronic circuit of conserve space in order to reduce cost is monolithic chip, this chip design becomes to provide necessary function, be the character (together with suitable sensor head) of the related printed material of sensing and the output that produces certain form, for example by driving that this output of one or more LED or audio converter normally can be listened and/or visible.This electronic circuit is a form with the ASIC (application specific integrated circuit) that is connected with power supply, sensor and output device usually.In addition, this sensor element generally includes certain type switching mechanism, and for example around the ring of " pen " point, this ring encourages this electronic circuit when nib leans against surperficial going up.Want printing printing-ink on the surface area of sensing, then the infrared absorption character that for example depends on this printed ink of the electronic circuit in the sensor element can be listened or visible signal is reacted by producing.The assembly of ASIC, sensor and power supply can be " sensor assembly ", and this module is included in the suitable housing to form the complete sensors parts.

Be designed to the printed material that to cooperate with it for this sensor element, a kind of mode that presents it is a form with the question and answer volume, the user faces the problems and one group of possible answer on this question and answer volume, a common answer is correct and other answer is wrong, by stamping the printed ink that a slice has suitable infrared absorption character near printed answer, the user can be correct or wrong by telling this answer on the sheet that this sensor element is placed on this printing.Thereby the sheet of these printings normally with different colours for example red, green, yellow and blue print they look like different from attracting, but one of them (corresponding correct option) contains some carbon blacks in black treatment of printing ink (wherein as feeling that very each sheet of situation of seeing is to handle printing by four looks).Other sheet can not contain the carbon black of carbon black or complete different brackets, thereby can make sensor assembly distinguish correct option and wrong answer.

Expect above-mentioned modification easily.For example, the early learning books may require the user to determine that the fruit shown in which kind of is from certain given alphabet letters for example " a ".The picture that its relevant example for example can illustrate apple and apricot represent (utilizing infra-red absorption levels to be higher than the ink printing of given threshold value) and other fruit for example jujube, banana, tangerine, green plum and lemon but be lower than the picture that the printing-ink of this given threshold value prints off with the infrared absorption program.A kind of alternative method provides the labyrinth type multipath of certain form to be represented, wherein selected path surpasses the ink printing of this threshold value with infrared absorption and other path is lower than this threshold value.If slide, for example can indicate this sensor element " in orbit ", and if to leave the red light that this paths output can leave correct path with the indication user be form by utilizing green LED along this paths.

This instructions and the WO-A-88/05951 that provides the development of the technology that illustrates among the WO-A-83/02842 reach certain business success, reach on the satisfied result but find in the reality to be difficult to that the manufacturing of printing material and sensor assembly is remained on the printing material that can utilize any sensor pen and any cooperation.

Although WO-A-88/05951 discloses a kind of sensor element that has programming mode and small display curtain, the dexterous degree of the action that this parts can reach is still relatively limited.

As explanation among WO-A-83/02842 and the WO-A-88/05951, the quantity of the different infra-red absorption levels that can tackle is relatively little, and this seriously limits flexibility of operation.In addition, not always as far as possible easily at first to show fully the infrared absorption printing ink sheet that can not find out by bore hole and the difference between the infrared external reflection printing ink sheet.This problem determines in US-A-4627819, and its suggestion is a kind of to utilize the dot pattern of printing to overcome the method for this problem, to attempt providing difference to complete undetectable infrared external reflection.It should be noted that the illustrated invention technology of this instructions proposition this article not only may be used on relating to printed material and pen or excellent education and the entertainment systems as illustrating among the WO-A-83/02842, can also be applied to so-called " invisible bar code ".

US-A-4627819 proposal scanner can have multistage sensitivity and propose the different band of five kinds " dot densities ", but wherein do not provide the accurate structure and the operation of such scanner in detail, and the dexterous degree that the technology of utilizing US-A-4627819 to illustrate reaches is still relatively little.

We have found significantly to improve in these patent specifications the basic methods of determining now, and especially provide and can determine the modified sensor element that uses together with printed material under the satisfied mode the education that realizes unusual extentization and recreation and user.

Can change the feature of from top table, choosing and/or use separately or in combination according to the special-purpose of imagination widely.In other words, can make up with the different interactive sensor elements/printing material that is provided under the varying environment in the different feature of combination under the different modes.

Like this, according to a particular aspects of the present invention, the various combinations of interactive printed material and sensor element can be provided, they comprise and have the printed material that printing is applied to the inapprehensible information of the on-chip people of watching, wherein this sensor element is suitable for the character of this printed material of sensing and does not debate not each Printing Zone on it, this sensor element comprises display screen and is suitable on this screen showing that one group is watched the people to show the fine arts face of different conditions to this, and wherein this sensor element be configured to be similar to the animal or human shape simultaneously this screen to be positioned to the position of this fine arts face corresponding, and wherein this sensor element comprises the sensor head of the end points that is positioned at this human or animal's shape.

For this product of less children is very attractive, if if for example personage's commodity shape and this screen and inside programming are suitable for providing various demonstrations especially like this to the similar known shape of style of pen or rod.Particularly, thus the face on this screen can be cartoon make lip and voice output synchronously and also eyes can make and move at random or nictation, it is " work " illusion that face is provided thus.

On the diverse grade on the target market of interactive printed material/sensor pen combination, be suitable under various combinations, providing much complicated in fact teaching or review material according to technology of the present invention, more options question and answer material perhaps for example is provided, and it can and check the test of having learned the viewpoint of content or being used for realizing own management type from the viewpoint of amusement from study.Thus, another wide aspect on, the invention provides the combination of a kind of interactive printed material and sensor element, it comprises and has the printed material that is imprinted on the inapprehensible information of on-chip observer, wherein this sensor element is suitable for the character of this printed material of sensing and does not debate not each Printing Zone on it, and wherein this sensor element is configured to distinguish each district and provide with to the measurement of this character and/or with the intelligible output of people of the results change of this measurement by the character of measuring printed material under at least five kinds.

As available and as discussed above in the common prior art, the form known of teaching and entertainment material is, printed material and be designed to hold and the sensor pen or the rod that contact with this printed material by the user, thereby can this pen or the parameter or the character of its printed material part of being contacted of excellent sensing, wherein trigger actual detection process by switchgear by the excitation of the contact between printed material and this pen or the rod, and wherein this pen or rod comprise for example visual display unit or can listen output of output unit, and it is according to the regular drive of programming in advance in sensor assembly that this display maybe can be listened output.

According to a wide aspect of the present invention, respond the switching of this switchgear, excitation this parameter that this sensor sensed or the value of character after this switchgear excitation, the sensing value of this switchgear switching timing and this parameter or character changes to the combination on another value, changes in the character of finishing journey that show on this visual display unit or the response of reflection in audio frequency output.The parameter that can switch the time and sense or the value of character are regarded three inputs that the microchip that for example is stored in pen and rod is kept away the complicated process of storage as, consider that in real time all three inputs are so that determine related specific output according to programming, for example whether it is the certain material that shows on the visual display unit, by the specific word that suitable audio converter sends, melody or other can be listened output or the combination of the two.Can reach ambidextrous mutual between printed material and the sensor element by programming cleverly, to give these parts " intelligence " atmosphere.At this printed material system user is comprised under the situation of the picture that utilizes sensor element to finish some operation and/or word instruction especially like this.If the user ignores the instruction of these pictures or word, this sensor element could produce the output of pointing out this point, and for example it can provide the user " to read instruction again " or " no by suitable chipspeech! Follow the path with nib ".

All these can reach by suitable programming, wherein the programming microchip of sensor element inside can be in fact be found out the implication that extracts from the list entries of order, then according to the implication work of this extraction and provide and encourage user's operation sensor element under suitable mode itself.Very briefly, can be programmed to pen and rod when you are printing and tell you what is next when bringing into use it on the page.

Promptly towards younger reader " work book " and more conscientious examination or review auxiliaryly, should be noted that for two types materials within the various improvement to the prior art that illustrates previously, it is of paramount importance using and can debating other grade in a large number.When using sensor element/printing material to make up, only to debate a small amount of grade, this may for example pick up correct option for " operation separately " on the text from four, may be enough as if these parts.But, when pre-prestige alternately when becoming task to a greater extent, during arabic numeral that for example sensing mixes continuously under correct order, the requirement that can debate more grade becomes much bigger, and self calibration also becomes much bigger to guarantee consistent all the time performance demands.

Can under variety of way, produce the printed material of a part that constitutes interactive system of the present invention or print article, but, because printed material will reasonably must apply suitable attention with the requirement of cooperation ground work together with sensor assembly on the typography that adopts.The same with the situation in above mentioned the disclosing, the preferred printing process of producing printed material is four look technology printings, be that material is to utilize so-called four kinds to handle that colors are printed and utilize difference batching in the employed four look technology printing-inks to provide invisible between the printed material different piece maybe can not understand difference, perhaps more specifically, use two types black ink, wherein a kind of containing high absorbs infrared carbon black and another kind does not contain.

Thereby it is high the absorption to infrared radiation that the standard industry black ink contains a large amount of carbon blacks.But, can utilize other " black " material to obtain printing-ink not difficultly, for example introduce dyestuff, although thereby the not obvious absorption infrared radiation of this dyestuff is the high bore hole that absorbs looks like black in visible spectrum.Alternatively, can not use Mysticum printing ink also to use Mysticum printing ink to print off color chips in other cases in some cases.By adjusting the silk screen density of printing, the color chips that do not contain Mysticum printing ink can equally with the color chips that contains Mysticum printing ink look like black.

Each printing district on the printed material is adopted the single parameter of wanting sensing, infrared absorption for example, can make sensor element debate not some different states according to different infra-red absorption levels routinely, even but can debate the quantity of other different brackets and be still relatively little for example maximumly between 5 to 10 in that self calibration facility (further explain the back) is set on the printed material, and when the high-end work down of this scope, be difficult to more reach to the quality control of sensor assembly and to the requirement of the technology controlling and process of printing in order to ensure this combination reliable error-free operation in actual use.But, exist wherein requirement under more than 10 kinds different conditions, to debate other example, according to a particularly preferred characteristic of the present invention this can be by sensor element being arranged to just do not check the single character of printed material but check on it two or even three character reach.

This can be by selecting suitable character and the thing realization that detects or measure this character being set in sensor assembly to printing.Although the present invention is not subjected to this restriction.It is color that its one makes things convenient for example.

If for example utilize industry yellow at the phase dialogue paper or other substrate on print off the printing sheet, if it is very little then to shine this sheet uptake with sodium yellow.If contain the sheet of industrial viridescent or industrial fuchsin on the other hand with identical gold-tinted irradiation, then the absorbed gold-tinted in these printing ink reduces thereby the meeting of the gold-tinted quantity of reflection is obvious.Similarly, can select other spectral color.If for example sensor element can be debated other five kinds of different colors and be contained the device that can debate other six kinds of infra-red absorption levels, then utilize this sensor element simultaneous to check that it is 30 kinds of different states that the printingout of printed material can debate other 6 * 5.Owing to can distinguish 30 kinds of dissimilar printingouts, can produce and use the complicated of 26 letters or " intelligence " recreation under the variety of way.

If sensor assembly contains the content that suitable microprocessor or ASIC and memory stores pre-programmed, then for example can produce the sensor element that a kind of object for appreciation " combines recreation into syllables " and the combination of printed material.Under a kind of simple form, can internally be programmed to sensor assembly and say (by chipspeech and converter) certain given speech, then the purpose of this recreation is correctly to risk this speech.By one after the other this sensor element being applied to the letter of choosing from the alphabet of printing (wherein each alphabetical combinatorial property differs from one another) in succession, whether this sensor assembly can detect the user and select correct letter to risk the speech that had before sent under correct order.In case detect this order from detection in succession, this sensor element could send suitable congratulations message, and is for example " well-done if the letter that user's pickup order is correct! Have a try now and combine into syllables ... ", new phrase wherein is another speech of selecting at random in a large amount of speech of storing from this sensor assembly.

In a kind of relatively directly development of this system that has just illustrated, when being applied to this sensor element on the alphabet letters of printing off at every turn, audio converter can be said " speech " of and this letter correspondence, for example " eh ", " bee ", " sea " or the like.

Can imagine the various modification of this method and can in single basis " book ", provide these modification, for example on page or leaf in succession, provide different recreation by one group of printingout, for example wherein can debate the programming " code " that can correspondingly make up this sensor assembly understanding when this sensor element success sensing is taken on other top of every page by this sensor assembly from this top, and this code to make the programmable electronic circuit in this sensor assembly be that different " recreation " is worked.

As easy understanding, operation requires sensor assembly to have the memory stores that the relative complex of various operator schemes is selected in permission by this way.This sensor assembly can be complete during manufacture pre-programmed, but this is not preferred, because mode and printing material that the use of this sensor element is limited in according to a kind of pre-programmed use operation together.In fact this can not use it according to the pre-printed material that is not stored in the new model operation in the sensor assembly.For this reason, wish very much to have in the sensor assembly reprogrammable district of storage data and carry out reprogramming according to the printed material that uses together with this memory member.This can reach like this, for example makes printed material related with a simple chip, and this chip comprises the good programmed instruction of storage and contains certain type output block, for example with can be to the infrared transmitter form of its feed-in coded data stream.The infrared sensor of sensing part module forms part and can catch electronic circuit in this data stream and this sensor assembly and then this data stream is converted to and be used for the behavior of this sensor element adjusted to and the operator scheme of the new suitable programming that the desired behavior of this specific printed material is mated.

Such as noted, the present invention is valuable especially in study or the system of review field.For example, it is contemplated that one is reviewed problem that exercise paper comprises that displayings printed off under a suitable sensor element and the literal and selection that may answer, wherein each answer is positioned to the printingout of being with look against one.The user for example is configured to the sensor of pen to this sensor element, leans against printingout and points out to select by the character of this printingout of sensing.Depend on the result, this sensor element can be reacted in certain suitable mode, for example to just indicating " right or wrong " according to determined answer.

In fact can debate not each answer sheet by normal ocular vision, their color difference is not for example seen but they important is not both.But even exist under the situation of " correctly " answer, providing than answer only to the user of sensor element of the present invention/printed material combination is very beneficial to the still information more information of mistake.

Can thereby very effective teaching can be produced with a large amount of different state of the printingout correspondence of the printed material of institute sensing and/or entertainment material reaches this by guaranteeing that sensor assembly can be debated not if desired.Thereby, for example under simple more options problem condition, can be for example a correct answer of coding and four incorrect answers but also these wrong answers of differently encoding in five different answers, thereby this sensor element can provide the reaction that is cut into the true of the answer mistake of not only pointing out the user and can also provides more direct targeted guide.For example, under the situation of simple numerical estimation problem, it can be approaching can having a direct correct answer and other answer, not too near or too far away, thereby the user is can be to this problem surprised and rational answer considered a period of time.

Under these circumstances, can make various visible colors and sightless carbon black/infrared not absorb black printingout according to the present invention a large amount of various combinations are provided together, thereby can for example send suitable speech message from the chipspeech and the converter formation part of this sensor element during for example according to certain color chips, this concrete message is to choose from the message of storage on a large scale.

Attempted producing the education utensil in a large number, the product of selling with LeapPad and Tomy TalkingBooks entitling for example, wherein book has been added intelligence and user and must tell electronic circuit also to open the page or leaf that launches in which is played, thereby electronic circuit can be made suitable feedback to this outstanding page or leaf.Usually this is by realizing by the promoter region for the suitable printing of every page of unique location, and the circuit in the electronics tablet below this excitation book and this can tell the user with the finger or the position of pressurizeing with the special pens that is connected with this tablet.All need to do like this but whenever turn over a page,, recognize and by the promoter region of printing until the user if there is not printed material can not respond.

The education book material that can utilize the present invention to be manufactured on to overcome this problem under two kinds of distinct methods.In one approach, the page or leaf/book that sensor element is programmed to generally all correspondences works.All grades are preallocated, pure reaching on every page graphical content from one page to the change of descending one page and by means of the game technology of slowing down the apparent repetition.When the user followed the instruction of printing on the page, hiding coding caused sensor element to change its mode of reacting according to its inside programming.

In a kind of more complicated method, sensor element is programmed to has game, this requires each new task coordinate responses.This can automatically show certain by sensor element and suitably the numeral or the symbol of print job/activity correspondence are realized.Only when finishing each task, just show new numeral.This new numeral can be next in succession task or the new distribution of selecting according to previous performance.The each charter that uses of user can be different in this way.If program allows to allow the user to cross the task of demonstration.

These the two kinds methods that can reassign the mode of procedure operation constitute another key character of the present invention.

Such as noted, sensor assembly is preferably with in the face of related specific printed material and checks oneself and self-alignment method.Like this, for example can on printed material, debate not a series of different zone of printing or sheet and randomly also comprise and debate the zone of not printing, thereby printing area can be mainly due to calibrating for example ability of the different value of infrared reflective of character that this sensor assembly debates other institute sensing that improves for this.

Such as noted, sensor element preferably includes one and makes its work, promptly triggers the switch of the detection process of measuring character.The inside programming of sensor assembly can be such, if preset time this switch of dead then make this module enter sleep pattern and in case power up and enter calibration mode, thereby first thing that the user does when the material that uses according to the present invention's production is at one that wants subsequently sensing concrete printed material calibrating sensors parts.This is always not desirable, because the user is tending towards ignoring this " housework ", but as explained later, can also calibrate again " just at work ", promptly when using this sensor element on the printingout in succession of a part at printed material of the effect recreation or the task of inspection.

In order to produce stable foundation sensor element of the present invention/printing material combination self calibration is important, on printing quality, suffer inevitable variation because when observing, can make each four looks technology Printing Zone of differential responses with sensor assembly, printing ink rate of application for example, silk screen separates, base paper or stamp variation in other raw material of this material thereon.In these variablees, the accurate response in any given printing district exists variation range.

Mark several regions on a kind of Calibration Method that realizes sensor assembly on printed material, one of them zone is the not printing area of basic or substrate material and the quantitatively corresponding quantity of wishing to detect different response grades in other zone simply.Thus, if for example wish to debate not on the basis of six kinds of responses of single character grade, this printed material can have one and not print district and five printing districts.

By sequentially sensor element be applied to this clear area and then these five print in the district, the response that can determine these six districts is infrared external reflection for example.Then can contrast these values, for example infrared external reflection that this sensor assembly is read during the calibration process or absorption, the processing of each corresponding data in printed material district of assessment inner that these are imported in succession and sensor assembly inquiry.Although these values can slight change without doubt, thereby in the tolerance limit band that the value that draws when internal arrangement becomes response is assigned to sensor assembly sensing test pieces on the specific grade is easily presetting.

For example, if the amount of infrared radiation that forms the part reception for the infrared gatherer of blank and five grade sensor pen under any yardstick is respectively 96,80,63,49,38 and 21, then can inner this sensor assembly be programmed to discern corresponding to a kind of grade in the response grade in following five kinds of scopes: 78-82,61-65,47-53,38-41,16-25.Notice that thereby these scope each intervals do not exist overlapping.Can be on the one hand suitably select amount of space between these scopes according to the changeability degree of complexity of in sensor assembly, setting up and the printed material that causes according to the specific typography that is adopted on the other hand.High more each the response band of the electronics complexity of setting up in the pen each other can be near more, thereby during sensor parameters is fallen at interval can reduce to use this time and cause the possibility of " can not discern " grade.If this occurs, can be arranged to sensor element point out the user " to try again ", because can in printing the district, occur changing, for example owing to hold the sensor element variation on the sensing that causes of corner cut degree really with respect to printed material by what the user controlled.Again apply sensor element and can obtain to be assigned to response on the grade in the related grade very continually.Can also become this component programming the number of times or temporal the closing on of detection this " trying again " prompting whether to cross to a certain degree, if then point out the user to recalibrate this sensor assembly, for example as previously explained above this sensor element one after the other is placed on one group and prints on the sheet.

As top pointing out, carry out self calibration when can also (and in fact best) making sensor assembly on printingout in succession, use this sensor element.If when this module is arranged to debate several different brackets of an other given character and expection and is respectively printed sheet and have with the accurately corresponding character of these grades, this particular importance.If sensor assembly finds that detected response as one man is higher or lower than desirable target response for a string printingout, then can by the electronic circuit internal blas in the sensor assembly measure baseline in case the most closely with the theoretical expectation responses match.

More generally, self calibration or again the calibration can compensate the changes of properties that some can influence sensor element.The front mention sensor element be designed to will with the typographic variation of its mutual material, but they are not only variations.The operating characteristic of sensor head self is among other variation that can point to.The preferred sensor head that uses is based on semi-conductive assembly, becomes relatively little although utilize Modern Manufacturing Technology to make, and variation is inevitable, and can compensate them and also cause and can use relatively cheap member; Tight more their cost of the performance tolerance limit of semiconductor subassembly is high more.Sensor head was from the distance on printed material surface when another variable was the generation sensing.This can depend on the sensor head and the definite geometric configuration of member on every side.Equally, if only rationally making these requirements under the tolerance limit, the price of sensor head assembly can keep low price.At last, although utilize modern batteries and battery technology power supply characteristic with remaining stored electric energy, for example the variation that dies down of power supply is very little, has slight the change on performance inevitably, just exhausts battery or this little variation of accumulator changes into big change approaching.

To the electronic circuit in the sensor assembly suitably under the programming, these parts can also detect since when change must by the user for example utilize a string different printingout of pointing out above to carry out conscious self calibration and/or when the operation that self calibration no longer is enough to keep satisfied these parts can point out the user for example to change battery.

As top indication, equipment of the present invention comprises printed material and sensor element in fact.When the sensor assembly in this sensor element senses certain character in this printed material zone, need to produce (although always not immediately) noticeable reaction.

In order to produce the reaction perceiveed of in fact carrying out sensing, provide the indication of carrying out this sensing in the time of can being built into certain regional character of at every turn utilizing its sensing printed material to sensor element.Sensor element is applied to preferably causes energizing switch on the printed material, this switch triggering sensing step, and this for example also triggers from as the visible signal of the flash of light of the light emitting diode of the part of sensor element or trigger earcon for example beep sound or " card is taken " sound.Afterwards a kind of method is useful especially under the situation that becomes the single and related mark sensor of pre-printed test according to equipment disposition of the present invention.May need the user to finish the entire chapter test, for example from one group of each problem possible answer, select the user to think correct answer, and answered the score that all problems just can show test afterwards.For user feedback having been selected the fact of certain concrete answer, can become " card is taken " sound to this sensor device by sending the beep sound that to hear at the answer selection Qu Shangshi that prints at every turn, can also obtain feedback by comprise " card an is taken " switch in point, this switch provides the mechanical force feedback of undue concentration and machinery " card is taken " sound that can hear.

The simple output automatically that provides when sensor element uses can be provided as in this automatic indication that sensing occurs.But this sensor element can comprise other output block, and the character for sensing of printing in the zone is depended in concrete output.Thereby, in WO-A-83/02842 for example under the situation of the simple amusement of illustrated type or early learning recreation, this output can be got the form that can listen output and/or visible output, with face expression effect above-mentioned is example, if be that the face of leaving behind is selected correct option then face for smiling if select wrong answer.This can be accompanied by audio frequency output, and this output can be form with voice if desired, the change of the mouth shape of these voice and the screen display of representing face is coordinated mutually, thereby this thus sensor element is seemingly in the intelligence that in fact demonstrates certain program in a minute.If sensor assembly is configured to store from the data of previous sensing activity and then not only according to the printed material district that senses recently but also produce output, especially such situation according to user's previous action.

The output of the third type can regard as more complicated and for according to of the present invention be of great value for the equipment that in the more options quiz, uses, wherein the mode with score shows output on the display screen of certain form that can only set up in this sensor element when finishing test.This display screen can also show out of Memory, perhaps alphanumeric ground or utilize suitable icon.

In this respect, this is valuable especially with the situation of the many answers review that the next problem that will answer provided the numerical value indication or test paper must to select correct option likely for user wherein.This prevents that the user from becoming confusion and preventing that especially the user from answering same problem secondary or missing certain answer.

It should be noted that, in the test that has the more options answer or review under the situation of volume, sensor element is required debate other degree may be relatively little.In fact, sometimes utilize the sensor element of two grades only debating other character to be satisfied with fully simply, but, for example utilize five grades of character and do not debate not that they are obviously beneficial because this can produce can by the own storage of these parts needn't begin to test or review exercise before carry out the review books or the paper of reprogrammed.

For example, if question and answer volumes comprise respectively have a plurality of may answers one of them be 20 problems of correct option, can utilize the different stage of some for example infrared external reflections to print off the correct option sheet, each correct sheet indicates these parts to provide correct option, and incorrect answer or all have the printed design of the response that provides same program or (best) has a rank in two kinds of ranks, wherein each problem is alternately put each printingout corresponding to wrong answer on one of these two kinds of ranks.This can be picked up by the internal logic of microprocessor in the sensor device and suppose correctly to have answered a basket, the problem quantity on then microprocessor can make the test from this specific basket decoding and for example should be with the object time of how long answering all problems.Utilize unduplicated fourth class level sequence on the mathematics, for example 32 variablees on the length can be finished this point quite easily.If because the user is provided with adequate preparation, sensor element can not felt detected rate sequence, then can show or can provide one with listening and preferably go back and take an examination next time and preferably do the message that some review work before.

In any case because to the complicacy of the decoding of the thing that all can not see on the part, the user can not determine to be included in the value sequence of printing the coding of hiding in the sheet easily, thereby suitably the sensor element of programming can seem when the paper textbook uses together and demonstrates tangible intelligence with reviewing paper or reviewing.

Such as noted, detecting under some initial conditions, sensor element of the present invention can comprise that another is the output block of form with the irradiation unit, it is suitable for shining when detecting this input and the detector head adjacent areas of this sensor element.Especially according to of the present invention interesting and cause in the curious progress, printed material comprises the material of printing near a plurality of answer sheets understood, this material is with the ink printing of not seeing under the general illumination, but when shining with black light it to become be visible, and wherein this sensor element contains near ultraviolet emission irradiation part.By this way, thus for example when being chosen to the merit answer, can excite in the sensor element this irradiation part to watch the user of this printed material to see that to a miracle new epigraph occurs.Alternatively, if for example utilize ruddiness or green glow irradiation not to see so that drawing mark can become eye-catching especially.

The another kind of sensor element output may be to listen output, and sensor element is built into provides audio frequency to generate particularly, and this can provide music output.In a simple embodiment, each grade can corresponding each beat, thereby can write down tune to contact this tune of reproduction as a string printing sheet and by making this sensor element sequentially print sheet with each on paper.Alternatively, tune can be got the form of printing bar, and wherein the character of this bar is along its length variations, and then sensor moves along this, along with its character of sensing this printing bar that advances and the tune of broadcast and this printing correspondence.This can be absorbing, can be changed by the user thus because play the speed of this tune.With regard to audio frequency output, sensor element output can be the uncomplicated relatively quite neutral music beat of tone color that for example simply generates, perhaps, certainly it can be much complicated for example issue out beat to tone but its tone color corresponding to piano, harpsichord, guitar, trumpet, large size or whatsoever.In any such sensor element, appropriate device can be set from some different " musical instruments ", to select, for example be arranged at first move in the printingout sequence of utilizing sequential query to obtain information encoded of this sensor element and carry out under the pattern that musical instrument selects, after this these parts can send the tone (tone color that has selected musical instrument) that can listen and performance are ready to represent it.

Come down to when continuous when the character of utilizing sensor element of the present invention that this sensor element is measured is arranged to corresponding to tone and this correspondence, this is interesting especially.Produce legible tune along the path slide sensor parts of printing in advance, and this sensor element be placed on other zone, for example such as other substrate of fabric or print the surface, on can produce corresponding and interesting response.

With regard to the overall shape of sensor element, it can change very widely, but usually most convenient ground is that the slender bodies with certain form is a form, is commonly referred to " sensor pen " or " rod ", for example as shown in the above-cited instructions of delivering.This elongated pen can comprise suitable power supply, conventionally is one or more battery, the switch of certain form and the sensors that are positioned at certain form of an end that are placed in the suitable compartment.For example, it can get the form of optoelectronic components, and its adapts to when being energized emitted radiation sequence (for example infrared radiation) and with the radiation detection parts that are suitable for measuring the printed material radiation reflected amount thereon of putting from the end points of this sensor element.Such as noted, this end generally includes the pressure switch of certain form so that trigger radiation string and sensing volume reflection.

Sensor element also comprises certain type processing electronic circuit.This can change to complicated Reprogrammable microprocessor chip or reconfigurable ASIC from simple pre-programmed fixed routine logic chip.Under latter event, can or reshuffle by any realization reprogrammed of means easily, for example, the direct electrical connection of input, the perception loop connects, infrared I/O unit of coding that uses during for example computer peripheral equipment and central PC " wireless " connect or upload/download data between PC and the PDA for example.Last a kind of is particularly preferred because it can not only make sensor element and PDA or PC mutual and can also utilize the microchip of the permission infrared communication on the card front cover on certain page that for example is attached in the book or that be embedded in book.If only need rearrange or reshuffle a spot of data, this in addition can utilize the printing bar or the band of printed material to provide, sensor element along seal bar scanning with " reading " data and change the behavior of sensor assembly.

Adopt programmable microprocessor chip or ASIC also to allow sensor element to note timing much morely, for example be applicable to the time span that encourages and/or realize this excitation in succession of approaching switch (this can tell whether its sensor head of sensor element just moves on the variable properties road of printed material) that triggers character and measure.

The another kind of possible input of this microprocessor is the sensor element the held angle to printed material, and this can utilize the suitable design that approaches switch to the proximity sense head to detect.

The various technology that are used for improving the complicacy of sensor element described above cause can production interactivity sensor element/printed material combination, it is mutual under the mode that complicated, user are ignorant of, and it is very complicated teaching and entertainment material, especially wherein certain page of material or the different material of interactive mode opened and the difference of the interactive mode of sensor element and identical printing material is opened or page provide possibility.On a kind of meaning, sensor element seemingly from the page or leaf printed or open pick up intelligence and utilize this intelligence with the user can not be immediately clearly mode revise its factum, but this correspondence every content of understanding of printing on volume or the page or leaf and the fact of whatsit for the certain meaning of user, because this content can observe and explain.The thing that can observe and explain can be word, picture or the combination of the two, and mutual between the content of awaring understood on the printed material, sensor element and print between the image that occurs on mutual and user and the display that can not perceive between the page or leaf understand mutual three kinds of interactive modes provide the various prior aries of utilizing described in the instructions of quoting previously inaccessiable or under very large expense, just can reach at least enrich mode of operation.In addition, certainly, depend on the complexity of programming and calculate recreation that education and amusement market have become gets used to the dexterity and the complicacy that are reflected in the product that this field provides at present very much by the what is called that occur recent years.The I/O parts that utilization has type display screen or monitor and certain type for example keyboard, operating rod, mouse or the computing machine that is exclusively used in operating unit (for example unit of selling by trade mark PLAY STATION ) are highly satisfied as study and the game experience that media obtains, thereby but this need use the expensive equipment of complexity and usually be the fixed equipment PC for example that is inserted in the domestic environment in the conventional electric power line significantly.But the corresponding recording unit for example cost of laptop computer is very high, even the less handheld device of real price for example is still expensive with the palm machine or the PDA of suitable Games Software programming.On the contrary, by utilizing these technology, need not low equally especially such as the special-purpose printing-ink of conducting fluorescence printing ink if the cost of sensor element can keep the cost of low and printed material according to the present invention's explanation.

If the order and the temporal variation of the field sense are considered in the programming in the sensor unit, can be according to the dexterity that set up another kind of degree in the parts of the present invention.Whether this means can with respect to printed material by different way physics movable sensor parts obtain various results.Like this, sensor element can be contact and then each specific region of printed material is disengaged with as sensing sequence independently, perhaps, for example, can be placed on these parts on the material then and slide, thereby change with this parts below and by the change of its observed printing from the signal of sensor head along its surface.

Utilize suitable programming to make up, this can be used to provide various " special-effect " that seems to have " intelligence " as the magic and this can produce the mode of countless design amusements or educational material.

Embodiment

At first with reference to the Fig. 1 in the accompanying drawing to Fig. 4, can see that the sensor unit shown in it is configured to the face 2 humanoid thing in the highest flight of a circular.This face is actually that lcd screens below the ring frame 3 constitute by being installed in.

As can be as seen from Figure 1, this face be stylish, comprises the mouth of two eyes, two nostrils and a smile.The lower end of health is one can be press fit into annulus 5 on it to cap 6.In the ring 5 suitable sensor is installed, for example combined type infrared emission LED and infrared reception semiconductor detector.Cap 6 looks like two pin when being configured on being put into health.Can hitch cap by being with 7, thereby it can not lost.

Suitable power supply is installed in the inside of this sensor element, electric circuitry packages and other member, and their detailed operation structure can change on a large scale.This electronic circuit for example can not be programmed to when not shining the sensor of ring in 5 on the substrate to be guaranteed when promptly this sensor unit does not use to become the expression of the face on the screen 2 and for example expresses disappointment as shown in Figure 3, and wherein especially the display area of usefulness 8 marks of the expression face on the screen 2 is downward now.

In the time will using these parts, cap 6 is thrown off from this termination and can be returned to the demonstration shown in Fig. 1 and 2 the detection that enters light is mounted to very simply.

In the use can with user's hand catch this unit as shown in Figure 4 and then this personage " stand " and is printing on the top of distinguishing, for example children apply flexibly on the book.

It is contemplated that various mutual according to the sensitivity of this sensor units and the printing of book.As very simple example, this book can be that not book is debated in simple many answers, is printing the animal picture of four titles below for example illustrating, the animal correspondence of wherein having only a title and being described.Each title next door can exist one to print sheet, and the user attempts determining the correct name that prints off, promptly reads it.If title is correct, this face can continue to smile, and can the smiling face be projected on the paper on every side from the LED that shelters that puts this sensor element health as shown in Figure 4 simultaneously.This illustrates in 12 places in Fig. 4.If select wrong answer, the face of projection can not occur and suitably change expression on the screen 2.By using different printing sheets and can not debating not sensor element from several differential responses of each printingout, variation can be provided with interesting mutual.For example, in more complicated self-learning system, can there be the single problem that for example has ten answers and print sheet accordingly.Certainly, one or may two correct answers cause screen display 2 to smile and image 12 occurs.Can organize ten answers near next, this can cause the curious or fascination expression of the face of screen 2, other answer may be to cause the full of prunes answer that shows shown in Fig. 3, and one of them answer may be represented " serious mistake " fully, and this causes demonstration face that magnify rather than that close on the screen 2.Simultaneously, can be arranged to this sensor element to send suitable noise, if perhaps in fact these parts contain chipspeech and send congratulation, the word of sympathizing with or encouraging.

Fig. 5 illustrates some typical way of publishing illustration on the printing page or leaf in the book of applying flexibly that can use with sensor element shown in Fig. 1 to 4.Illustration is the copperplate printing 14 that dog is shown in this concrete example, black and white or more generally colored.For above focusing on of user is put into the parts of Fig. 1 to 4 where and is pressed in to reach desired effects, illustration has " button " of some printings, button can appear at illustrated edition on one's body as shown in 15 or appear at a side as representing with 16.

Fig. 5 just applies flexibly an example of the type of page, and it is contemplated that much more very other apply flexibly the type of page.Such as noted, applying flexibly page for example provides pen to slide to produce the path of suitable effects along it, perhaps it can for example have a series of numerals that mix, need contact these numerals in turn with the termination of this sensor unit in order to produce desired effects, the illustration of applying flexibly the another kind of type that comprises in the book can be an implicit pattern, for example is superimposed upon the staggered degree of absorption to infrared spectrum on the illustration.The user can be by being placed on the point of sensor unit on the illustration and the pen that slidably reciprocates under motion of oscillatory type sawtooth or line motion obtains reaction from illustration.This for example can be used for from the story-book of band figure producing suitable voice or from the personage's who draws greeting, perhaps produce the personage's who illustrates on the display screen caricature.Another kind may be that the illustration of printing is opened, and it has some at the article shown in the left and right hurdle of center separated time two sides.Instruction can require the user to be placed on the termination of sensor unit on the article in the left hurdle and the termination of this unit that then on paper, slides and cross center line it slide in the right hurdle " pairing " on.This can utilize illustration or the speech that prints off carries out.

Utilize legend Fig. 6 to be illustrated on a period of time how to use sensor unit.In the recreation of six types of the left border marks of each illustration of six illustrations of pie graph 6 and to be described as fixed point, tracking, associating, line, jump and sliding-type respectively mutual.When stain on the termination of line indicates the end points of sensor unit to be placed on the paper (wherein right rather than left from the alignment of an extension, as perhaps to leave paper this moment from the alignment left side of an extension rather than to the right).Thereby for fixed point and jumping type recreation, sensor unit one after the other contacts and then moves with the printing page or leaf.This unit senses the character rank at every turn and all makes indication, and illustration 6 illustrates seven kinds of different grades.As can be seen, the recreation of not all these types need be used whole grades.

In the paired picking exercise of describing in the above, Fig. 6 is in " associating " pattern shown in the 3rd section operation, wherein for example the infrared absorption of the center line at the middle part of page or leaf is appointed as grade 100 and this and illustrates and pen is placed on to have sensing value in the left hurdle be that to cross sensing value on 20 the something then be that to provide the sensing grade similarly be 20 correctly join a little for 100 center line and then successfully picking up.A special advantage of this special type is that it changes tolerant especially to printing.Pen is successfully operated required whole programmings it is reflected rightly, for example when pen run into one its show green glow when sensing the printing ink sheet that character has the value identical with the sensing character of printing ink sheet above it initially is placed on or send the triumph beep sound or say " well-done ".The absolute value of character is not important, but each printing image in only need guaranteeing equally, the character of background paper itself and central area separated time differs from one another.

It is contemplated that and handle input so that other method of different outputs to be provided, the content among Fig. 6 is not exclusive.

Now forward Fig. 7 to 15 to, they illustrate the various sensor pen unit modification by student's the auxiliary configuration of review.

Fig. 7 to 10 illustrates four kinds of possible bodies designs of pen, each comprise one wherein sensor tip 21 at one end and LCD display curtain 22 near the elongated shell of the other end.In addition, this unit has two buttons 23,24, and it is adjacent and another is nearer from point 21 to be arranged to one and screen 22.End cap 25 can be press fit on the termination of this unit, and as shown in Figure 11 a, 11b and 11c, extract from real sensor easily, reverse (keeping tying down) and leave the groove 26 of the complementation on the opposite side of the screen 22 of making peace greatly that is arranged in shell 20 in by contact pin 27.

This pen that uses together with printed material 29 shown in Figure 2, printing material 29 for example can be got the form of reviewing books, and every page of book is reproduced some problems, the adjacent some printed material sheets of possible answer that each problem has and prints.Look like and so on example on the front of one page of this book shown in Figure 16, four are numbered 1 to 4 problem shown in the figure.Each problem is surrounded by the rectangle frame of printing in turn.Be quaternate cartouche below the problem that each prints off, each ellipse contains a possible answer of printing off and has a left end that is positioned at it and can be placed on top colored printing sheet 32 to sensor tip 21.Each sheet 32 be different and for example also different on infrared external reflection on can color, sensor tip is placed in " mistake " answer and still is placed in " correctly " answer so that can make sensor element debate other user.

As can be from finding out Figure 13 a and the 13b, shell 20 be configured to and can grasps easily shown in Figure 13 a or hold with the right hand easily shown in Figure 13 b.Under these two kinds of situations, can utilize thumb action button 24 and this button itself can serve as switch, for example then cause the character of its printed material sheet of this moment taking of a sensing.This is useful under the review situation, and its middle school student have the control to the record of each answer, and promptly record can automatically not take place with the improper heart of possibility; On the contrary, the only just answer of recording learning when user's thumb presses the button 24.

As can be from finding out Figure 12 to 14, LCD Panel 22 be configured to have some icons.Figure 15 clearly show that these icons (and may as one group of complete contrast region).Can find out from this figure that two buttons 23 and 24 are designated as mode button and start button respectively, can be used to start the clock operation by start button (these parts are powered up the back) for the first time, this for example indicates on first row of display.

The printing page or leaf of book 29 can for example comprise one " test finish " district in the lower right corner, when pen be placed on that this printings district goes up and when pressing the button 24 this district cause sensor pen to go demonstration percentage score first.

The next line of the display shown in Figure 15 comprises four zones, they can optionally encourage in case if the answer that points out faults illustrates " cross " if point out that correct option illustrates " number of colluding ".This can for example be the part (except mode of learning icon and suitable button) of the unique excitation of display if this sensor unit is used for mode of learning.Like this, under mode of learning rather than review or test pattern, study can be selected a possible answer, pen be placed on it above, touch the button and learn to have selected correct still incorrect answer immediately.

As shown in Figure 14, this can have one the irradiation circular cone throw among Figure 14 with the projection part on the zone of 31 marks.If if this irradiates light be from the ultraviolet light of suitable LED and on the printing page or leaf of book this irradiated region 31 comprise legend with fluorescence (but invisible usually) ink printing, thereby this UV printing ink discharging fluorescence user can see the additional message of understanding 24 the time when touching the button.

Figure 17 to 20 illustrates the CONSTRUCTED SPECIFICATION of this unit, but and total particularly shell 20 at one end have a round hole 33 of 32 of wherein adorning switch.Figure 17 illustrates each member of 32 and an end of printed circuit board 35, and this circuit board has the main electronic circuit that is used for analyzing sensing result and drives LCD 22.As shown in Figure 17, sensor head 32 comprises outer metal housing 36, have four round metal cylindricality inner sleeves from the arch sheet 38 of one end extension, the ring body 39 that has the part spherical surface has outside open truncated cone end 45 and such as the mounting pipe 42 of the photoelectric device 42 of semiconductor emitter/receiver member.Article four, connect lead-in wire 41 and extend from device 42, these lead-in wires are connected with suitable track on the printed circuit board 35 when this part is assembled together.The polishing that outside open truncated cone end 45 surrounds the device 42 that has lead-in wire 41 transmits and receives face, and and arch sheet group 38 work to hitch the ring body 39 of part sphere together.Can also be as seen from Figure 19, under the position shown in this, the lower edge contact of arch sheet 38 discord betal cans 36 is especially when arch sheet 38 faces toward the space 34 of following circumference of shell 36.

When the termination of this sensor pen forward near Figure 20 in during with the printing books of 50 signs or paper surperficial, the spherical annulus 39 of part at first rotates, thereby even this sensor pen no-fix becomes the surface 50 that faces toward printed material really perpendicular to 50 annulus, 39 level lands, surface of printed material as shown in Figure 20.This works also to prevent that veiling glare from entering, thereby helps photoelectric device 42 character of the printing image of its below of sensing exactly.This is the position shown in the right side of Figure 20.Cause arch sheet 38 to open and the lower end of betal can 36 contact with annulus 39 by the surface of sensor pen further being pressed to printed material downwards, the triggering actual sensed.Simultaneously, pipe 40 moves down and along with ring 39 is maintained fixed by paper 50, end 45 no longer contacts with ring 39.This causes the contact between member 36 and 39 and disconnects member 39 and 45 contact, thereby trigger the electronic circuit of installing on the printed circuit board 35 so that exciting light electrical part 42 usefulness infrared lights shine this zone 50 of printed material, cause and to estimate from its emission and absorbed amount of infrared light.In case sensor pen is left paper 50, this triggering discharges.

By operate mode button 23, can enter mode of learning by this electronic circuit, for example can make it by serve as the complicated reprogramming of photoelectric device 42 receptions that the infrared signal of coding is served as receiving sensor this moment.The known various parts that are used for sending the infrared signal of coding especially may use PC, palm machine or laptop, and they suitably have the infrared emission technology and have proper procedure as the source of the infrared signal stream of this coding.
