Description
Technical field
The present invention relates to photoelectric field, relate in particular to a kind of contactless touch screen control device.
Background technology
Nearly 5 years, smart mobile phone has captured the primary seat in mobile communication terminal market, meanwhile, in order to meet the diversified life of consumer and amusement demand, various application software produce thereupon, when service is provided, the method for operating that is also mobile terminal is that the interactivity between user and equipment has proposed new requirement.12 traditional key operations and full keyboard equipment afterwards, can not meet the operating function that a feast for the eyes App provides for user far away, now, touch display screen technology is arisen at the historic moment, employing the most simply, mode makes consumer's complete operation easily, reaches unprecedented man-machine interaction and experience.This technology is applied to panel computer, notebook computer, various terminal devices such as display screen significantly simultaneously, has captured rapidly market.It is the most natural input medium, along with modern is to conserve space and man-machine display interface is aesthetic and the lifting of interactive requirement, and being replaced by touch screen gradually of traditional mechanical key mode.
Distinguish according to know-why, touch-screen roughly can be divided into five basic kind: vector pressure sensing technology touch-screen, resistive technologies touch-screen, capacitance technology touch-screen, infrared technology touch-screen, surface acoustic wave technique touch-screen.Wherein early stage vector pressure sensing technology touch-screen has exited historical stage, although infrared touch panel is cheap, its housing is broken, easily produces light and disturbs, and distortion etc. in curved surface situation, causes service condition little.The accurate positioning of resistive touch screen, but price is quite high, and be afraid of to scrape rapid wear.Surface acoustic wave touch screen has solved the various defects of touch-screen in the past, clear uprising, is applicable to various occasions, and defect is that water droplet, the dust of screen surfaces can make touch-screen slow up, and even cannot work.Capacitance touch screen design theory is good, although its image fault problem has much room for improvement, but it is still one of most widely used touching device of present stage, its principle is to stick the metal capacitance material of layer of transparent at glass surface, these special metal capacitance materials are called metal level, have multiple touch positioning units on metal level.In the time that finger (electric conductor) touches on metal level, the electric capacity of electric shock will change, and the oscillator frequency being attached thereto is changed, and is changed and can be determined touch point positional information by survey frequency.
Along with the development of intelligent terminal, touch display screen becomes indispensable display device, although but touch screen operation is convenient, but require to point in person operating of contacts completely, many times can not meet the demand of use, the significantly touch display screen in particularly meeting, classroom, the human-computer interaction operation that this is original smoothness has brought the limiting factor of a lot of inconvenience.Except operational restriction, the free-hand operation that touches completely also easily causes certain dirt and damage to screen, is also unfavorable for the consideration of health aspect simultaneously.If can have a kind of method under the condition of non-touching, complete the operation of touch screen, realize good human-computer interaction function, will be the much progress in intelligent terminal control operation.
Although existing touch screen technical operation is convenient, it but has certain qualifications, and such as must we self pointing in person contact completely, this has just brought certain operational issue.Such as cold winter, what we often ran into cannot operate touch screen product with the both hands of gloves exactly.The tactile mode of hand is difficult to be applied to long-range significantly touch display screen in addition.Along with scientific and technological development, no matter be to give lessons or the meeting of company lecture in campus, or even our family's LCD TV, touch screen is all widely used, but most significantly touch display screen just carries out some simple page turnings with laser pen conventionally, luminous point instruction can not complete the operation of other complexity at all; The restriction of service range and screen size simultaneously, cause us cannot carry out in real time manual operation, this just waste in vain good touch screen resource, also make again consumer's interactive reduction in use, the stage of having got back to original non-touch display screen simultaneously.Except operational limitation, the free-hand operation that touches completely also easily causes certain damage to screen, the long-term existence of these oil stains, spot not only has influence on the display degree of screen, the sensitivity of operation is also had to very large impact simultaneously, it is blunt that a lot of consumers find that the long-term touch screen using can produce operant response, or even the phenomenon of sliding screen, this has affected smooth user's experience that intelligent terminal brings greatly.And in public, some touch-screen equipments are for a large amount of floating populations, free-hand operation does not also meet health simultaneously and health is considered easily, and practical, touch screen easily has but become the approach of transmission.
Therefore, need a kind of contactless touch-screen control program, can realize the control to touch-screen in the situation that not contacting touch-screen.There are a lot of scholars both at home and abroad for above-mentioned relevant, thinking and scheme that close problem has proposed multiple solution, roughly have following several.
One, be also concentrate the most, scheme that user is maximum, be exactly the thought based on image processing.In the front of screen, assigned address is placed one or more video camera, and there is comparatively clear and definite requirement its angle and position, then the many application drawings before screen is looked like to carry out Quick Acquisition in short-term.PC, by the collection to image, forms contrast with original image, through complicated analytical algorithm, draws operation conclusion, and indicated number screen operates.This thought is applied in different patents, paper, relates to the instruction operation of laser pen, the operation of gesture, or even the operation of some three-dimensional postures.But it is very high that the shortcoming of this scheme is environmental limit to require, need to set up external camera head is connected with PC with touch screen displays, do not there is general applicability and animal migration, and computing machine also needs just can complete aforesaid operations through the analysis of complicated algorithm and image processing techniques, need to there is a powerful database to support, image to multi collect is stored, is analyzed, thereby completes the analysis contrast of image, ensures the accuracy of operation identification.Meanwhile, the collection of image all needs there is certain consideration to environment, light, operator's clothes etc., situation error complicated and that inevitably generation is identified.
Its two, be to make an issue of at screen itself, lay two-layer capacitor layers, between there is certain gap, and touch positioning unit between two-layer capacitor layers is interspersed.Because while increase along with the area of the touch unit on the metal level of capacitance plate itself, can realize contactless input, finger needn't contact completely with screen, but while having certain distance, and the touch positioning unit after increase just can sense and operate the capacitance variations that the action of object brings.But because the area that touches positioning unit has increased, in the situation that the capacitance plate total area is set, can cause the number of touch unit to reduce, and then make the precise decreasing of input, the position detection accuracy that this kind of scheme operates while utilizing the capacitor layers of multilayer to lay to improve noncontact.Although this scheme has realized contactless operation effectively easily, there is certain limitation for non-contacting distance, and still helpless for the operation of giant-screen, it is not very large that the man-machine interaction of contactless function screen is experienced to upper meaning.
Its three, be also instantly very popular a kind of scheme, i.e. order control operation.Eyeball can reflect infrared light spot while irradiation through infrared beam on cornea, and infrared light spot can form the differential seat angle of two directions anyhow with pupil center, and this differential seat angle changes along with the rotation of eyeball.The built-in camera of screen top is a miniature pick-up unit, can read difference size, itself and pre-stored eye is controlled to the interval angle reference comparison of focusing.Then, through a series of image processing, sight line analysis, motion analysis etc., notification screen equipment complete operation.This kind of method seems novel convenient, but because the everyday actions of eyes is too complicated, in operating process, there will be unavoidably extra operation, such as nictation, suddenly turn order and see other places etc., these casual little tricks also can be collected by micro detecting device, are used as operational instruction, thereby bring a lot of extra calculated amount, bring operational erroneous judgement simultaneously.In addition, the degree of restriction of the method is also very high, necessarily require screen to there is positive camera head, or external camera head, and in the scope that eyes must can photograph at pick-up unit, still can meet the demands for the Miniature Terminal such as mobile phone, panel computer, at a distance significantly display screen cannot realize operation.
In sum, existing touch-screen existence easily causes certain damage, easy communicate illness and much in occasion, has the problem that can not directly use manual manipulation touch-screen touch-screen with hand direct control, and existing scheme existence realization complexity, the poor reliability of under the condition of non-touching, touch-screen being controlled and the problem that cannot carry out to long-distance large touch-screen contactless operation.
