As seen from the above technical solution provided by the invention,
The present invention is directed to some disadvantages for solving existing scheme,
Current some schemes cannot be converted into actually available product, these schemes fully rely on the image continuously taken pictures and know Not, the disadvantage is that, on the one hand, the difference with the identification of taking pictures of the hand of other simple backgrounds, books pattern multiplicity, some patterns with Finger or rod is similar is easy to obscure, only leans on image recognition completely, has then but been mistakenly identified as indication, another party without giving directions sometimes Face, what operation of most of the time user all do not have, and identification of continuously taking pictures at this time is invalid poor efficiency, can also occupy and set Standby processor memory etc. causes other work that cannot complete well, taking pictures while and completing other works to consecutive invalid Make, then cause cost excessively high the excessively high system of hardware requirement excessively complexity, actually available product can not be formed,
Therefore the current actual product for identifying and directly being given directions on books with finger of not taking pictures,
Certain class of the invention gives directions information or graph text information to identify equipment, can take pictures and identify that finger is given directions on books at which The picture and text of position or indication and do not have to by special pen device, can take pictures identifies which this book which page,
Consider it is in one's hands to be forward extended out when being given directions on books, indication information of the invention or graph text information identify equipment quilt Setting is placed in front of books, and hand or book page turning etc. reflect infrared or ultrasonic wave, is only occurred really in book information or indication information It just takes pictures when variation identification, just identifies, avoid continuous when most of the time user does not operate when needing to identify The poor efficiency taken pictures, and hand is not in not have compared to only identifying it is relatively accurate by continuously taking pictures to infrared reflection Give directions and but accidentally know to there is indication, can directly be given directions on picture and text with finger can reliably carry out giving directions position identify and/or Picture and text identification, character image, which this book, which page of indication etc. according to identification display relevant information or can issue diaphone Frequently, do not have to by special pen device, it is very easy to use,
It is still to be identified by taking pictures that the present invention, which specifically positions, and infrared or ultrasonic wave only plays a part of to trigger identification of taking pictures, Therefore infrared or ultrasonic wave arrangement also with fully rely on infrared or ultrasonic wave and be different to be accurately positioned,
The specific location of the infrared principle of the present invention and non-monitored hand, as long as but triggering can be forward extended out by reader's hand, Therefore act on and arrange upper, the general vertical and horizontal friendship of transmitting not identical to position that with general transmitting intersect infrared or ultrasonic wave anyhow Infrared or ultrasonic wave is pitched to position and need vertical and horizontal both direction transmitting to obtain lateral and vertical coordinate, and the sensor the close fixed Position is better, and infrared or monitoring ultrasonic unit of the invention is to play triggering, it is contemplated that complete with display screen and the cooperation taken pictures At, it is contemplated that indication is to forward extend out hand to give directions, therefore is especially arranged before infrared or monitoring ultrasonic unit books, when with The infrared ray that can reflect monitoring unit transmitting or ultrasonic wave are stretched out one's hand to which triggering is taken pictures in family, and few as far as possible infrared or super Sound wave as long as can easily monitor that reader's hand forward extends out, for example can be set and be arranged in display screen left and right side Most 6 of the first infrared or monitoring ultrasonic unit total number,
The first described infrared or ultrasound unit lower edge apart from height of table top is higher than 2 centimetres and 4 centimetres of highest or is higher than 4 lis 5 centimetres of rice and highest are higher than 5 centimetres and 7 centimetres of highest or are higher than 7 centimetres and 9 centimetres of highest, and general books are lower than 2 lis Rice, avoids the interference of books itself in this way, it is further contemplated that the height of hand,
Specifically,
One,
A kind of most simple and direct concomitant regimen is proposed, for equipment in front of books, number is one the first infrared or ultrasonic wave The characteristics of monitoring unit, hand can reflect infrared or ultrasonic wave to triggering it, this scheme is that one the first is infrared or ultrasonic Wave monitoring unit can not cover books, therefore be totally different from the common cross bearings such as infrared ray, and common red The positioning of outer or ultrasonic wave as far as possible comprehensively covering and need multiple units the first be infrared or ultrasonic on the contrary, this scheme only includes one Wave monitoring unit, therefore equipment is simple, especially monitoring unit is arranged in front of books, allowing for indication is to forward extend out hand It gives directions, will not usually interfere, then stretched out one's hand forward when giving directions, can be taken pictures by infrared or monitoring ultrasonic unit to trigger Identification originally to be stretched out one's hand, this additional rolling one if can actively shake before it if due to indication Lower there is no too many inconveniences, instead realize system very easy, may also can reflect when certain books are browsed infrared or ultrasonic Wave, but can be as needed in specific product design to triggering it, for example does not go to distinguish and integrate identification, if being to browse New page then issues the correspondence audio of new page, issues if having indication really and gives directions corresponding audio or display indication pair The content etc. answered, or then specific identification can also be distinguished in advance, for example combines the second infrared or ultrasonic wave being subsequently noted Unit, which can be distinguished browse or give directions, triggers infrared or ultrasound unit etc.,
Another simple and direct concomitant regimen, equipment is in front of books, it is contemplated that children's book equipped is much 16 professional storytelling in a local dialects opened, after expansion Wider, the farthest horizontal distance for giving directions information or graph text information identification equipment front to control each other is greater than 10 centimetres at least two Most 6 the first infrared or monitoring ultrasonic units, in this way when being given directions with the right hand, often over the monitoring unit on the right, When being given directions with left hand, often over the monitoring unit on the left side, if being shaken before monitoring unit if, only than most simple side More the first the infrared or monitoring ultrasonic unit of case, but use feeling is more natural, for example, giving directions in the left side of book then on a left side Side is shaken, carrys out movement unnatural in this way without hand is reached right side.
Two,
Another concomitant regimen, described infrared or monitoring ultrasonic unit include that at least two of horizontal distance less than 3 centimetres is most 6 the first infrared or monitoring ultrasonic units and most 6 of described at least two the first infrared or monitoring ultrasonic unit Transmitting and/or receiving direction are that diverging is outside in floor projection, specifically, such as equipment, in front of books, display screen is right Side at least two and/or the first the infrared or monitoring ultrasonic unit of left side at least two, and their direction is thrown in level It is that diverging is outside on shadow,
Such benefit is, due to display screen, monitoring unit can not be arranged at display screen, and monitoring herein is exactly empty It is white, but the infrared sensor that can also monitor, and need in front of display screen for dissipating or intersecting is again seldom,
Hand when one adult indication is at least 8 centimetres wide in terms of front, generally at least 5 centimetres of the hand of children wide,
There is a pair of of the infrared of diverging transmitting that can complete to monitor substantially in display screen any side, although not to books range Really covering, such as the first half of books do not cover, but the specific location of infrared principle of the invention and non-monitored hand, And be to ensure that and monitor that reader's hand forward extends out, it is real as long as the close reader's this side for monitoring books such as infrared Border research and development show have a pair of infrared or ultrasonic wave dissipated just to can guarantee reader's hand when giving directions substantially in display screen any side Infrared or ultrasonic wave can be easily reflected by forward extending out, and triggering be completed, easily, if respectively having a pair of of diverging in display screen two sides The infrared or ultrasonic wave of transmitting then covers closeer, gives directions on the large scale books of more convenient expansion.
Three,
In view of page turning or give directions can all trigger infrared or monitoring ultrasonic, in order to can be distinguished before image recognition so as into The hand-manipulating of needle is to identification, and the present invention is in addition to the first is infrared or monitoring ultrasonic unit is also provided with second infrared or monitoring ultrasonic Unit, second infrared or monitoring ultrasonic unit include three kinds, at least 6 centimetres most 12 centimetres away from height of table top of A class and It is higher than described at least 2 centimetres of the first infrared or monitoring ultrasonic unit, at least 6 centimetres most 12 centimetres of height away from height of table top Not only the height of hand can be higher than to avoid the indication of hand but also be able to satisfy most of books page turning triggering, most 13 centimetres are according to 32 13x18 centimetres of books size is opened, lower than this height ability page turning triggering, such second of A class infrared or monitoring ultrasonic list Member is triggered in page turning and will not be triggered when giving directions, and B class is away from height of table top 12 centimetres of detection ranges of at least 3 centimetres of highests Shorter than 6 centimetres and shorter than described at least 2 centimetres of the first the infrared or monitoring ultrasonic unit of detection range, such B class second The infrared or monitoring ultrasonic unit of kind is triggered in page turning and will not be triggered when giving directions, and C class is shorter than 6 due to detection range It is centimetre general will not be triggered when giving directions and also with it is nearest described in the first infrared or monitoring ultrasonic unit horizontal distance it is big In 5 centimetres, such second of C class infrared or monitoring ultrasonic unit is located at different from the first infrared or monitoring ultrasonic unit Horizontal position and also have spacing greater than 5 centimetres, shaking of the hand before the first infrared or monitoring ultrasonic unit when indication It will not be triggered to that C class is second infrared or monitoring ultrasonic unit, to form differentiation.
Four,
User often in finger point on books, only oneself is intended to refer to a little and is not desirable to equipment and is identified,
But only from finger on books in view of this image, and indistinction,
The present invention proposes targetedly scheme special consideration should be given to the demand, and monitoring distance is less than 6 centimetres, this is allowed for Books generally have about 3 centimetres of lay edges, in addition books may have a distance apart from equipment, when monitoring distance is less than 6 centimetres Elemental user will not trigger infrared or ultrasonic wave in finger point on books, when user needs equipment to identify, Yong Hu The indication that reaches before first shakes the hand of stretching once before infrared or monitoring ultrasonic unit, and such equipment can just be triggered The identification of taking pictures given directions.

The monitoring modular includes one or more infrared or monitoring ultrasonic units, described infrared or monitoring ultrasonic list Member is infrared or ultrasonic wave emits reception group, and the triggering of the monitoring modular includes passing through described infrared or monitoring ultrasonic unit Emit and receive the infrared ray reflected or ultrasonic wave and trigger, the indication information or graph text information identification equipment are placed in Described infrared when identifying or monitoring ultrasonic unit of taking pictures in front of books books on desktop emits to one side of books,
Described infrared or monitoring ultrasonic unit includes the first infrared or monitoring ultrasonic unit, the indication information or picture and text Information identification equipment, which is placed in front of books, takes pictures identification to books, the first described infrared or ultrasound unit away from It is the height of desktop with a distance from the first described infrared or ultrasound unit lower edge from height of table top, is higher than 2 centimetres and 4 centimetres of highest Either it is higher than 4 centimetres and 5 centimetres of highest or is higher than 5 centimetres and 7 centimetres of highest or is higher than 7 centimetres and 9 centimetres of highest, generally Children's book equipped thickness is lower than 2 centimetres, almost can be more than all children's book equipped thickness if height is positioned above 4 centimetres, high For degree preferably at 7 centimetres hereinafter, such as 6 centimetres of highest, it is infrared or ultrasonic that this is that the height of hand when giving directions according to children is wanted to reflect Wave, this is highly just above the thickness of normal children's books, and can be triggered when reader gives directions,
The infrared or ultrasonic wave transmitting reception group of monitoring modular of the present invention, which is to ensure that, monitors that reader's hand forward extends out, therefore makees With and arrange it is upper intersect infrared or ultrasonic wave anyhow with general transmitting and differ widely to position, it is general emit intersect anyhow it is red Outer or ultrasonic wave needs vertical and horizontal both direction transmitting to position to obtain lateral and vertical coordinate, and the closeer positioning of sensor is more It is good, and infrared or monitoring ultrasonic unit of the invention is to play triggering, it is contemplated that it completes, examines with display screen and the cooperation taken pictures Considering indication is to forward extend out hand to give directions, therefore is especially arranged before infrared or monitoring ultrasonic unit books, when user stretches Hand can reflect the infrared ray of monitoring unit transmitting or ultrasonic wave is taken pictures to trigger,
And infrared or ultrasonic wave few as far as possible, as long as can easily monitor that reader's hand forward extends out,
Refer to when being placed in front of books with the indication information or graph text information identification equipment and take pictures and identify to books It is front that information or graph text information identification equipment, which are put, towards the surface of one side of books, and described infrared or monitoring ultrasonic unit includes It is giving directions information or graph text information to identify the first infrared or monitoring ultrasonic unit of positive one of equipment, and/or is giving directions Information or graph text information identification equipment front each other left and right horizontal distance greater than 10 centimetres at least two the first it is infrared or Monitoring ultrasonic unit and/or described infrared or monitoring ultrasonic unit include at least two of horizontal distance less than 3 centimetres It a kind of infrared or monitoring ultrasonic unit and described at least two the first infrared or monitoring ultrasonic units transmittings and/or connects Debit to be in floor projection diverging outward,
This is practical to propose three kinds of concomitant regimens,
A kind of most simple and direct concomitant regimen is proposed, for equipment in front of books, number is one the first infrared or ultrasonic wave The characteristics of monitoring unit, hand can reflect infrared or ultrasonic wave to triggering it, this scheme is that one the first is infrared or ultrasonic Wave monitoring unit can not cover books, therefore be totally different from the common cross bearings such as infrared ray, and common red The positioning of outer or ultrasonic wave as far as possible comprehensively covering and need multiple units the first be infrared or ultrasonic on the contrary, this scheme only includes one Wave monitoring unit, therefore equipment is simple, especially monitoring unit is arranged in front of books, allowing for indication is to forward extend out hand It gives directions, will not usually interfere, then stretched out one's hand forward when giving directions, can be taken pictures by infrared or monitoring ultrasonic unit to trigger Identification originally to be stretched out one's hand, this additional rolling one if can actively shake before it if due to indication Lower there is no too many inconveniences, instead realize system very easy, may also can reflect when certain books are browsed infrared or ultrasonic Wave, but can be as needed in specific product design to triggering it, for example does not go to distinguish and integrate identification, if being to browse New page then issues the correspondence audio of new page, issues if having indication really and gives directions corresponding audio or display indication pair The content etc. answered, or then specific identification can also be distinguished in advance, for example combines the second infrared or ultrasonic wave being subsequently noted Unit, which can be distinguished browse or give directions, triggers infrared or ultrasound unit etc., and one embodiment is as shown in Figure 2.
Another simple and direct concomitant regimen, equipment is in front of books, it is contemplated that children's book equipped is much 16 professional storytelling in a local dialects opened, exhibition Wider after opening, the farthest horizontal distance for giving directions information or graph text information identification equipment front to control each other is greater than 10 centimetres at least 2 most 6 the first infrared or monitoring ultrasonic units, in this way when being given directions with the right hand, often over the monitoring list on the right Member, when being given directions with left hand, often over the monitoring unit on the left side, if being shaken before monitoring unit if, only than most More the first the infrared or monitoring ultrasonic unit of simple scheme, but use feeling is more natural, for example, being given directions then in the left side of book It is shaken in left side, carrys out movement unnatural in this way without hand is reached right side.One embodiment is as shown in Figure 3.
Another concomitant regimen, described infrared or monitoring ultrasonic unit include at least two of horizontal distance less than 3 centimetres Most 6 the first infrared or monitoring ultrasonics of most 6 the first infrared or monitoring ultrasonic units and described at least two Unit transmitting and/or receiving direction are that diverging is outside in floor projection, specifically, such as equipment in front of books, is shown There are at least two the first infrared or monitoring ultrasonic units on one of screen right side or left side, and their direction is in floor projection On be diverging outward, as shown in figure 4, such as equipment is in front of books, at least two and/or left side at least two on the right side of display screen The first a infrared or monitoring ultrasonic unit, and their direction is that diverging is outside in floor projection, such as Fig. 5 institute Show,
Such benefit is, due to display screen, monitoring unit can not be arranged at display screen, and monitoring herein is exactly empty It is white, but the infrared sensor that can also monitor, and need in front of display screen for dissipating or intersecting is again seldom,
Hand when one adult indication is at least 8 centimetres wide in terms of front, generally at least 5 centimetres of the hand of children wide,
There is a pair of of the infrared of diverging transmitting that can complete to monitor substantially in display screen any side, although not to books range Really covering, such as the first half of books do not cover, but the specific location of infrared principle of the invention and non-monitored hand, And be to ensure that and monitor that reader's hand forward extends out, it is real as long as the close reader's this side for monitoring books such as infrared Border research and development show have a pair of infrared or ultrasonic wave dissipated just to can guarantee reader's hand when giving directions substantially in display screen any side Infrared or ultrasonic wave can be easily reflected by forward extending out, and triggering be completed, easily, if respectively having a pair of of diverging in display screen two sides The infrared or ultrasonic wave of transmitting then covers closeer, gives directions on the large scale books of more convenient expansion.
The first described infrared or monitoring ultrasonic unit causes the first triggering,
After the first triggering, if the indication information or graph text information identification equipment are arranged to special or preferentially carry out indication knowledge The other then described indication information or graph text information identification equipment are according to the information for including a width described image or several described images Which position what the word content and/or identification that identification is given directions were given directions is,
After the first triggering, if the indication information or graph text information identification equipment are arranged to comprehensive identification indication and books letter Breath is then described to give directions information or graph text information identification equipment according to the information for including a width described image or several described images The word content given directions and/or indication are which position and/or which this book and/or the comprehensive identification of which page.
These are arranged, and are allowed in addition to the hand of indication can reflect infrared or ultrasonic wave, page turning etc. also can, therefore in function On the first infrared or monitoring ultrasonic unit specific function is determined according to specific arrangement,
Emitting infrared or ultrasonic wave in this side of the front direction books of books can monitor whether that hand stretches out, for single page picture and text There is no problem, but when objectives are books, books page turning etc. also can infrared or ultrasonic wave, propose two schemes here,
A kind of scheme is, after the first triggering, if the indications information or graph text information identify that equipment is arranged to special or excellent It first carries out giving directions and identifies the then indication information or graph text information identification equipment according to including a width described image or several institutes It states the word content of the information identification indication of image and/or gives directions which position, it is special or preferential due to being already provided in this way Indication identification is carried out, therefore is clear function, single page picture and text are usually only given directions without page turning etc., can be easy to It is set as exclusively carrying out indication identification, and for books, picks up and put down books and page turning etc. also and can reflect infrared or ultrasonic wave, it can Distinguished with taking some measures, for example, be manually set as when needing to identify indication after having translated into certain page it is special or preferentially into Row gives directions identification, or there are also other monitoring means are such as other infrared or ultrasonic energy differentiation is page turning or indication, But no matter take any other technological means to distinguish, all meets this feature of the invention, i.e., the described indication information or picture and text Information identification equipment be arranged to special or preferentially carry out indication identification, be only set as especially by what means it is special or Indication identification preferentially is carried out,
Another scheme is, after the first triggering, if the indication information or graph text information identification equipment are arranged to comprehensive knowledge The other then described indication information or graph text information identification equipment are according to the information for including a width described image or several described images The word content given directions and/or which position and/or any this book and/or the comprehensive identification of which page are given directions, due to picking up Infrared or ultrasonic wave can all be reflected by putting down books and page turning and giving directions, and can not be distinguished in advance, but lean on image recognition, i.e., and first After kind of triggering, actually or equipment just identify indication page turning etc. by image recognition and identify the specific information or current given directions Page information.
