Description
Technical field
The invention provides a high sensitive and high-res optical touch control device, this touch controller also can be used as Venier controller, chamber (Cavity) has been arranged in this touch controller, be coated with a translucent sheet on this sky chamber, this translucent sheet has a smooth diffusing surface, and this sky is indoor still has a light source and an image detecting device.Produce the image that high diffusion is different from low diffusion while by detecting an indicant, touching this translucent sheet, learn the situation that an indicant contacts with this translucent sheet, and by this indicant of detecting while contacting with this translucent sheet, the situation of relative motion each other, draw signal, with the function that changes certain electronic device or the movement of the vernier on its display.
Background technology
On computer and electronic product now, many products are to rely on contactor control device to carry out interchange between human and computer and interactive function.These products comprise notebook computer, mobile phone, GPS (GPS), and electric game machine (Gaming device) etc.In the field of Touch Screen, whole industrial technology can be divided into resistance-type (Resistive type) and the large class of condenser type (Capacitive type) two haply, though its technical connotation has difference, but purpose is all to offer the not available convenience of a kind of conventional mouse of user-removal USB cable or wireless channel (Wireless Channel), and these to be all conventional mouse must will be used for being wired to objects on computer; Touch Screen is without this demand.Yet Touch Screen has a birth defect: Touch Screen, when a finger or needle bar, going to touch it when surperficial, lacks the precision (positioning accuracy) that measures this touch position; Owing to can't effectively overcoming this shortcoming, current Touch Screen product, and can't use in the electronic palette environment of office or specialty.
Restriction based on above, although current action electronic equipment provides the user that can leave to carry mobile convenience, but they can't input data give software (for example WORD (Microsoft's paperwork software), the PowerPoint (Microsoft's presentation software) of office use, or Spreadsheet (Microsoft's tentative calculation software) etc., so make it quite be limited on professional office purposes, and the reason of searching to the bottom is in default of locational accuracy.Figure 1 shows that traditional mobile phone (Cell phone), have a touching display screen on this action phone, some is practised in using such equipment person that it is referred to as to Smart Phone8.Note, have most icons (Icon) on this touching display screen, the area of each icon compared with the icon on general computer display screen large quite many, in order to represent some program or function.The quantity of these icons, represent that this action phone can offer how many different functions (that is convenience) of user simultaneously.The quantity of these icons but, in fact and very large (for example, five of more than tens), this is because the deviser at the design drawing timestamp, must take into account the size of the quantity of icon and people's finger simultaneously.As shown in Figure 1, when a finger tip 9 (Fingertip) touches undesirable position, it may cause once triggering four programs.
The Smart Phone8 of Fig. 1 is a capacitive Touch Screen.This type of design is generally that transparent thin-film capacitor is placed on Touch Screen, and places perceptron (sensor) in four corners of this Touch Screen.As this Smart phone (8), while being touched by foreign object, the quantity of electric charge in electric capacity changes to some extent, and perceptron (sensor) is that discernable stream electric current thereon also changes to some extent; By measuring the variation of electric current on each perceptron, traditional mobile phone is learnt the general location of the finger that touches its Touch Screen.Generally speaking, using the accuracy of the result that the method calculates not high, is fortunately that it only must meet the requirement that the user can not make mistakes when selecting icon and gets final product; As shown in Figure 1, due to the size of those icons all quite greatly, the degree of accuracy of its size is also relatively coarse.Due to the restriction in this design, make undersized electronic equipment as Smart Phone want input data to document processing software WORD running into, perhaps during tentative calculation software (Spreadsheet), face great difficulty, cause Smart Phone (8) several without the essence purposes in the application of above-mentioned this class.The net result of the restriction of this technology is, when these electronic equipments, during at the state of use, the operating state of the application software of its whole system or function, be often to only depend on several simple icons to present to the user.
As for aspect notebook computer (Notebook PC), similar problem is also arranged.It is used for the equipment touch pad (Touch pad or Mouse Pad) normally of moving cursor.The problem of the touch version (mouse pad) of this class is that its susceptibility and resolution are all not high.When the manufacturing technology that faces flat-panel screens (Flat Panel Display) is maked rapid progress, the performance of the touch pad of this class is but almost without too large progress over several years.Therefore, with the functions such as resolution, speed and multi-point touch of display now, compare, the function of traditional touch pad is too simple and crude, this causes the user of many notebook computers all it to be thrown aside, change and use conventional mouse, so that it does not need to change use habit ground, the vector value still hand moved is passed the notes computer back by USB or other transmission medium, for its control vernier.Matter it, mostly the problem of above-mentioned conventional touchpads, be to come from the deficiency of its resolution and susceptibility; And this is a root problem of conventional art in fact: although some user is still arranged on market, learning to deacclimatize the function of conventional touchpads, and managing to accept traditional touch pad, the problems referred to above still exist.For example, when the user will move on to the other end to an object in display screen from an end, if this distance is not short, the several steps of the common score of this user draw several times on touch pad, just can achieve the goal.
Take a broad view of the above, no matter be the touch pad of notebook computer, still the take action touch screen of electronic equipment, whole electronics industry still needs to find one, and touch-control system (or can the called after contactor control device fast and accurately, Venier controller, user's operation interface equipment etc.), with the action electronic equipment, integrate, form electronic equipment or a notebook computer that simultaneously there is speed and degree of accuracy, so can allow the user easily use the software of the class of the document software of class of WORD or other trial balance (Spreadsheet), and data is inputted exactly, set up archives etc.
Summary of the invention
The invention provides a touch controller (also can name for Venier controller), chamber (Cavity) has been arranged in this touch controller, be coated with a translucent sheet on this sky chamber, this translucent sheet has a smooth diffusing surface, and this sky is indoor still has a light source and an image detecting device.In the situation that best, the performance of this light diffusing surface, as same Lambertian surface; In the situation that inferior good, the performance of this light diffusing surface, can approach the diffusing surface of a perfect light.When doing optical analysis, this kind of light diffusing surface, can be divided into numerous facet to it and treat, each facet is scattered beam to all the winds all, and its intensity approximately is directly proportional to the cosine value (Cosine) of this scattered beam to the angle of this faceted normal.Due to this scattering phenomenon, the brightness of this Lambertian surface (Brightness, luminance, or radiance), no matter go from any angle, be all identical.The so-called semi-transparency property of this translucent sheet, refer to that light can penetrate into opposite side from the both sides of this plate, but, due to the diffusion phenomena through so-called Lambertian Surface height, object can't be differentiated at the formed image of the other end and shape.
Effect due to this Lambertian surface, make this translucent characteristic with strong scattered light, when this effect by force to a certain extent the time, by this light of translucent, no matter be from this that side of translucent, after the scattering of translucent through this, all become scattered beam.After scattering, be positioned at the body of the object in this slide distant place, be first to pass through this surface of translucent (being Lambertian surface), then arrive imaging after this other end of translucent, this kind of image be fuzzy, can't be by the identification body.This half slide system has been covered on chamber, and still there is an image detecting device its inside.Due to this translucent can be the light of the external environment condition from this touch controller, after being radiated on Lambertian plate, break up; Same, it also can be indoor from this touch controller sky, the light be radiated on Lambertian plate is broken up, therefore, after above two effects add up, outward appearance (outward appearance refers to the image of seeing in environment) and the interior sight (interior sight refers to the image of this bottom of translucent) of the even diffused of a brightness have been formed.Every and this Lambertian have the object of some distances, and after the diffusion through Lambertian surface, its image all can be fuzzy falls, and when this image fog arrives certain degree, this object can't be recognized by this image detecting device.
It should be noted that: (1) this to be positioned at empty indoor light source can be light emitting diode (LED), but can be also the light source of other type; (2) this image detecting device CMOS image sensor (CMOS (Complementary Metal Oxide Semiconductor) image detecting device) preferably, take and can see that the whole inside surface of translucent that covers top, sky chamber is felicity condition.Yet other image detecting device, as long as can see the whole inside surface of translucent that covers top, sky chamber, and can facilitate the position that determines indicator, also can use; (3) this Lambertian surface preferably has fine grain surface, the surface of other type, coarse grained Lambertian surface for example, through overetched surface, the perhaps surface of atomization, also can be used for replacing this Lambertian surface, just effect may be slightly weaker.The application of above these variations, still belong to interior scope of the present invention.
When an indicator (for example, a finger, needle bar, while or the equipment of similar functions) touching this Lambertian surface, some internal light that stem from this Venier controller are reflected back, form the image of an indicator illuminated, now an image detecting device will be detected the image of this indicator be illuminated, along with the movement of this indicator on Lambertian surface, one electronic circuit be connected with this image detecting device follows the trail of this image, the result of its tracking can be used to the vernier on the display screen of control action electronic equipment, this action electronic equipment at least comprises: notebook computer (Notebook PC), mobile phone (Cellular phone), GPS (GPS), game machine etc.In addition, this indicator can represent some elements on the screen of selecting this electronic equipment by mentioning the action of then putting back to this Lambertian plate.Further, especially working as touch controller of the present invention is used on notebook computer, it can allow that a plurality of fingers do the control of touch-control to it, now on Lambertian surface, can mark off one (a bit) predetermined place, this (a bit) place can be used for the operation pages scrolling, the image rotation, scenery amplifies in order to make this display screen reach effect that promotes susceptibility and resolution etc.
This image detecting device is for capturing the image of multiple relevant these indicators, and this indicator can be a finger under preferably selecting.At those,, there are one first image and the second image in the image of multiple the inside, and the inside of its image is cut to some scopes, in order to extract the motion-vector value, and, by this motion-vector, makes touch controller of the present invention be controlled a screen upstream target action.When touch controller of the present invention is used finger to be used as indicator, the protuberance on finger, groove mark, whirlpool, and intersection etc., can be used as the element that defines object.Now touch controller of the present invention will be followed the trail of those elements that are defined on one first image and those elements that are defined on one second image.When carrying out this tracking work, one can split those elements that are defined in those images with the electronic circuit of this image detecting device coupling from image, then the relatively change of their positions in different images, again those change amounts are converted into to motion-vector, this motion-vector is used to control vernier or other function on screen.

Embodiment
Fig. 2 A is depicted as the translucent sheet 10 be placed on equipment of the present invention, has the Lambertian plate 11 of a high nephelometric turbidity unit on this translucent sheet plate.When incident light is beaten on the surface 11 of this high nephelometric turbidity unit Lambertian plate, produced reflected light, scattered reflection light (diffuse reflection light), and lightlike lines such as number such as diffusion penetrating light (diffuse transmission light) etc.From physical definition, so-called Lambertian surface, refer to when light drops on this high nephelometric turbidity unit surperficial, by a large amount of scattering (Scatter), opened, so that the brightness that its whole surface presents is quite even, no matter the observer goes from any angle, be nearly all identical.This surface institute has the tropism (isotropic) of grade, to all directions are all effective up and down, certainly, also effective to spreading penetrating light.In other words, if an observer from the bottom of this translucent sheet 10, look, the surface that he sees is also a uniformly surface.It should be noted that herein, so-called translucent (Semi-transparent) refers to a light scattering phenomenon, makes light can pass certain medium or certain zone, but after the diffusion of certain degree, its imaging has made the profile of object a long way off can not recognize, or can't see at all.
In the touch controller of Fig. 2 B, chamber (Cavity, 12) has still been arranged.The translucent sheet that this sky chamber 12 is had Lambertian surface by this covers.Through a camera lens (lens), image detecting device 13 receives the formed image of light by diffusion.When in the face of context, this image is in fact that a brightness is quite even, fuzzy image completely, the source of its light is parasitic light from all directions in environment, after the surface 10 that shines translucent sheet, through the diffusion of Lambertian surface11, reenter and be mapped to image detecting device 13.If explain above-mentioned phenomenon from the angle of physics,, as shown in Fig. 2 B, after the light (Ambient light) of environment penetrated the surface 10 of translucent sheet, enter 12 li of sky chambers, due to the impact of the phenomenon spread, we are called Diffuse transmission by this phenomenon.Because Lambertian surface11 has high nephelometric turbidity unit, every outer object had with a certain distance from Lambertian surface, it is presented on image detecting device 13, is all the images without clear and definite profile.Therefore, between object and object, can't differentiate each other.
As shown in Figure 2 C, a light source 14, within being placed in sky chamber 12, preferably, in situation, this light source is to be made by LED (light emitting diode).This light source impinges upon light on this translucent sheet.Same, at this light source irradiation, after the surface 10 of translucent sheet, through the diffusion of Lambertian surface11, the light of some can be reflected back, and from all angles, is incident upon image detecting device 13, forms a fuzzy and uniform image thereon.The light penetrated from LED, after arriving translucent sheet 10, some can be because the relation of Transmission diffusion, be diffused in the external world, if the observer observes from top, may just think that some zone of this translucent sheet 10 is brighter slightly, but can't know its shape.If explain above-mentioned phenomenon from the angle of physics, as shown in Figure 2 C, after the light of LED penetrated the surface 10 of translucent sheet, reflected and return by Lambertian surface11, then entering 12 li of sky chambers, due to the impact of the phenomenon spread, we are called Diffuse reflection by this phenomenon, as for the light of some part LED, can inject in external environment through Lambertian surface, this now is referred to as diffuse transmission as us.
Fig. 2 D and 2E present the appearance 15 that the inside of translucent sheet 10 is seen.Image detecting device 13 interior seen be a fuzzy and uniform image, some brightness is slightly arranged.Shown in Fig. 2 F is the image that overlapping that image detecting device 13 is seen is got up, and it is by the above-mentioned fuzzy and uniform image of being manufactured by LED light source, adds the image of injecting image detecting device 13 from the external world and combines.As previously mentioned, the light of injecting from the external world is also the light of diffusion after translucent sheet, and therefore, image detecting device 13 can not seen the clear and legible image of recognizing.
Shown in Fig. 3, be to use an indicator (Touching device, or pointing device) to go to touch the effect produced after this Lambertian surface.This indicator can be any amount of needle bar, erasing rubber, pencil, finger 20 etc. different object.When this indicator (Touching device) while touching this translucent sheet, originally in the external world, injected the light of the translucent sheet of indicator (Touching device) below, will be blocked by this indicator, if now light source 14 does not exist or do not open, can make image detecting device 13 see a shade 21.If light source 14 is opened, put into sky chamber 12, what image detecting device 13 was seen is a surface be illuminated, and this surface is that this indicator contacts part with Lambertian surface, and we call it as the position 22 that this indicator surface is illuminated.Certainly, this position can be by 13 identifications of image detecting device out.Therefore, light in the external world adds the effect of room light source, overhead 14 synthesizeds, can be so that the indicator surface contacted with Lambertian surface produces a position of illuminating 23, by image detecting device 13, we can detect situation and the position of the movement at the position 23 that this indicator surface is illuminated.
It should be noted that indicator contacts part with Lambertian surface, owing to being shone very brightly by light source, its thin section structure can be by 13 interpretations of image detecting device out.For example, if this indicator is a finger, the thin section structure on the finger, as lines, groove, whirlpool, point of crossing of protuberance etc., all can clearly be sensed by the image detecting device.Feature structure on these fingers that are illuminated, be image detecting device in the present invention in order to monitoring and determine the basis of the amount of movement of indicator, touch controller of the present invention, then be converted into the position of the vernier in the display screen on electronic device according to this amount of movement data.
It should be noted that the defined vernier of the present invention, be divided into visual type (visible type) and not visible type (visible type) two classes, this two class all is applicable to the present invention.So-called visual type vernier refers to that this vernier has certain body (for example, an arrow) on display screen, can the person's of being operated observation obtain; So-called not visible type, refer to that this vernier can not direct observation of the person of being operated obtain, and it may be the memory cell (memory cell) in electronic device, or a parameter in software etc.For example, in the picture of general computer game, might not have the fixing vernier of shape (sometimes not having fully), the user for example, changes by so-called Venier controller (mouse) can be the function of the class of action (action of swinging as the baseballer) or audio, the state of the function of the object of these not visible types, normally be stored in the memory body of electronic device, or in the parameter of software, while removing to adjust the state of function of object of those not visible types by mouse as the user, the memory body of electronic device corresponding thereto, or the parameter of software, meeting thereby change, if this vernier is visual type, above-mentioned change can be exported to display screen again, make the content changing of display screen.Therefore, the defined vernier of the present invention can be shown in the picture element on screen for one (a bit), or be present in one in the electronic device memory body (a bit) memory body, by touch-control Venier controller of the present invention, the continuous renewal of the data of input, can in time change the content of memory body data, then be converted into relevant with the picture of screen (as vernier), or the function of electronic equipment other side relevant (as audio).
Shown in Fig. 4 A, be for example, to touch the right of the Lambertian surface on translucent 10 when an indicator (, pointing 20), and light source 14 is just when luminous, the image that image detecting device 13 is seen.This translucent 15 side in the face of the image detecting device, present a finger mark illuminated 23, and this finger mark is exactly finger and this translucent 15 place contacted.Physically, this finger mark illuminated 23 is the light due to light source 14, after shining finger, through reflecting, then passes through the outside surface of Lambertian surface, through translucent 15, then through empty chamber (cavity), formed image.As for being centered around translucent of the finger mark 23 that illuminates other place, due to no matter be the light from environment, or the light of light source 14, all by Lambertian surface, diffused away, its formed image is that a diffusion is even, without the low-light level plane of clear object.
As shown in Figure 4 B, if point 20 left sides that move on to the Lambertian surface on translucent 10, the surface 23 of the indicant be illuminated, the image that its place image detecting device 23 forms, can and then move on to the left side of translucent 10.If now make finger keep contacting with Lambertian plate, continue to move towards the left side, image detecting device 13 can, when the finger right-to-left moves, be followed the trail of some the thin section structures on finger.The electronic circuit be connected with image detecting device 13 can be tracked this thin section structure that is illuminated of the surface of indicant, conversion moving coordinate value, make a vernier on the display be connected with this Venier controller, can with movement.
If point the 20 Lambertian surface that left on translucent, the image detecting device can't detect any concrete object; Until this finger reapposes on Lambertian surface, the surface portion 23 that this finger is illuminated can reappear on Lambertian surface.For example, if finger shows the left side of dropping on translucent this moment, the surface portion 23 that finger is illuminated, also there will be on the left side.
Fig. 5 A is depicted as the image 41 that image detecting device 13 detects the surface portion that is illuminated of finger, because it is larger to point the strength of the Lambertian surface11 in translucent of 40 compressings, has changed shape.Although it is comparatively oval that the surface portion 23 that now finger is illuminated becomes, the above-mentioned electronic circuit be connected with image detecting device 13, still can discover the position of the finger that this pressurized, and the numerical value of this position be converted to the value of certain position of the display on electronic equipment or notes computer.It should be noted that, translucent 10 below other by finger, do not touched zone 15, impact owing to shining light on it and be subject to the diffusional effect of height, make the received image of panadaptor, can't have any cognizable shape or object.
Fig. 5 B is depicted as a finger 40 when the time is t1, and the ，Ci position, position of the formed directing object be illuminated 41 separately is converted into the position of the vernier of the display on electronic device, and this electronic device can be notes computer etc.When the time arrives as t2, point 40 rises, so image detecting device 13 can't be seen the surface (finger tip) 41 of the indicant illuminated again.The lower surface of whole translucent, present uniform diffusion light this moment, without any body, can recognize.Move to t3 when the time, point the 40 Lambertian surface11 that again go back to touch on translucent 10, the surface of the indicant that this illuminates (finger tip) 41 will occur again.In whole above-mentioned process (t1-t3), the vernier on display be present actionless.This kind is by the action of finger, from leaving Lambertian surface to getting back to Lambertian surface, can be used to represent the selection of vernier to certain object on screen, and trigger and carry out when finger is got back to Lambertian surface, the function that other is relevant, also can develop accordingly.Perhaps, if finger just moves after when the time is t3, touching Lambertian plate at once, this is the electronic circuit that indication is connected with the image detecting device, the vernier on display screen is done to the movement of (with finger) equidirectional.
Figure 6 shows that the bottom 60 of translucent 10 of seeing from image detecting device 13.Several indicant surfaces that are illuminated are arranged on Fig. 6, and what mean respectively is first finger 61 (they can be also a kind of indicator), second finger 62, and the third hand refers to 63; These three fingers touch on translucent 10 simultaneously.Although only shown three fingers herein, in actual operating environment, the quantity of these fingers (or indicator) can be more or less.These a plurality of fingers (or indicator), can be used for controlling a plurality of events on the screen of electronic equipment or notebook computer, and these a plurality of events, also can comprise the situation of a plurality of verniers.Perhaps, these a plurality of fingers also can be used for controlling other functions of electronic equipment.
This translucent some special area in the face of the surface 60 of image detecting device is can be connected to electronic circuit identification on this image detecting device out.First zone 64, be (Scrolling) for the image in the crawling display device, and the action of this scrolling is to form with the functionally coupled of vernier shifter of the present invention.When 61,62, or 63 fingers (or indicator) wherein are while being placed in this scrolling control zone 64 interior, can make the page rolling in the screen of notes computer, and its function class is like the function of the wheel of the scrolling page of general mouse.Second 65, zone is for the page in the screen of rotation notes computer.This function also with the function class of the wheel of some computer mouse seemingly.The 3rd zone 66 is that the function that is used to provide high sensitive and high-res is used; For example, if vernier is pointed to certain zonule on notebook type computer screen, similarly be lattice of trial balance (spreadsheet), or an English alphabet in document processing software, can reach purpose with this zone.As for other zone, they also can be used as left button or the right button that is equivalent to mouse, or a specific function on computor-keyboard.
Figure 7 shows that the electronic equipment that some can use vernier shifter of the present invention or touch controller.These equipment at least comprise desktop computer, notebook computer, panel computer (Tablet computer), have large display screen and can present the mobile phone of icon (icon), the palm action toy that some is welcome by young man and adult, global pick device (GPS) etc.It should be noted that optical cursor controller of the present invention, its physical size is with respect to the size of mobile phone, can do much smaller than general mouse pad (mouse pad) size with respect to notebook computer.This be often a necessity method for designing because in order not make mobile phone, game machine, or the volume of global pick device (GPS) becomes too huge, this method for designing is very necessary.If that but optical cursor controller of the present invention is done is larger, or, after having done large, it is placed on to the back side of hand-held electronic equipment, still belong to scope of the present invention.
Further, translucent with Lambertian surface of the present invention, the area that it is minimum, may diminish to approximately as the size of the circle of half centimeter left and right of a diameter.Such size, be used for operating the size of finger of hand-held equipment than major part also little.Now when this translucent by finger while covering, the light in environment can't be mapped on the Lambertian surface of translucent fully again, and the inner light in free chamber (cavity) is only arranged, and can illuminate the surface of indicator (finger).Therefore, the character shape on finger, such as the lines of protuberance, groove mark, whirlpool, or intersect etc., can allow the image detecting device be used for the movement of monitoring finger with respect to translucent, and and then the command and display screen on the movement of vernier.From considering of actual fabrication, the shape of translucent with Lambertian surface of the present invention, be not limited to circle; Other shape is such as rectangle, square, or any design that meets the hand-held electronic equipment, all can use.
Further say again, optical profile type vernier shifter of the present invention, except making, on the hand-held electronic equipment, also can be used in notebook computer, electronic writing board, plate type computer, e-book, electronic media player, or on other similar equipment.Conceivable arriving, optical cursor controller of the present invention or touch controller, can replace the mouse of desktop computer, if it and keyboard are combined, or combines with computer screen, can get rid of the demand of general masses to conventional mouse.
