Abstract
Produce the apparatus and method of touch-sensitive light spots in the plane, comprise at least one linear laser generating means, it is characterized in that, one or more laser beam emitting devices that can produce linear laser are placed in the outside at the plane induction region, plane induction region and parallel is with it pressed close on the formed plane of the linear beam that laser beam emitting device is launched, when other objects during from line-like laser beam flux institute shape plane one side touching plane induction zone, will get on the obstacle object because of laser, the pairing position of obstacle object forms one or more hot spots on the induction zone of plane.
Description
Technical field
The present invention relates to a kind of apparatus and method that produce touch-sensitive light spots in the plane.Can be used for indication or expression position, even can be applied to touch screen etc.
Background technology
The product of indication class is with a long history, on blackboard, indicated emphasis with teacher's pointer in the past, afterwards with laser pointer or laser designator, indicate by the bright spot that on screen, produces, developed again afterwards again and touch-screen, can directly on screen, indicate or even pass through the touch screen operation computer by finger, yet the touch-screen cost of giant-screen is still quite high, and to the requirement of screen also than higher, the technology that can realize touch-screen at present mainly be pressure-sensitive with infrared-type.The principle of using the pressure sensitivity technology is the pressure membrane inductive layer of being made up of a series of resistive film, insulation grid, conducting film one deck on screen.When on the inductive layer a bit receive pressure the time this point will connect circuit (what the product that also has adopted is opposite mode, makes this point cause short circuit).
The advantage of pressure sensitivity technology is to need not to use special-purpose pen, uses not sharp-pointed lip pencil thing to get final product, and is also lower for the requirement of power supply simultaneously, uses the USB interface power supply to get final product.But also there is inferior position in it, need exert oneself when that is operated exactly, and the time has been grown the user can be more tired, and reaction velocity also has delay slightly, and the size of blank is also restricted simultaneously, can not do too greatly.
Infrared technology is around " electronic whiteboard " infrared receiver and power valve to be housed, thus the scanning grid of formation level and vertical direction.When object blocks is lived in the grid certain to the scanning point of crossing of level and vertical composition, just can be by the level that is blocked and the infrared ray location positioning coordinate of vertical direction.
Infrared technology accurate positioning, precision do not need to use special-purpose pen than higher simultaneously yet, but in use but receive high light and other strong ultrared influence easily.
Summary of the invention
The present invention by adopting a kind of apparatus and method that produce touch-sensitive light spots in the plane, makes the electronic whiteboard of photoelectric technology can really become touch-screen, also can transform displays such as plasma, liquid crystal, rear-projection as touch-screen by photoelectric technology simultaneously.
The object of the present invention is achieved like this: the apparatus and method that produce touch-sensitive light spots in the plane, comprise at least one linear laser generating means, it is characterized in that, one or more laser beam emitting devices that can produce linear laser are placed in the outside at the plane induction region, plane induction region and parallel is with it pressed close on the formed plane of the linear beam that laser beam emitting device is launched, when other objects from plane that line-like laser beam flux forms during the induction zone of one side touching plane, will get on the obstacle object because of laser, the pairing position of obstacle object forms one or more hot spots on the induction zone of plane.
Described linear laser generating means is characterized in that it can being the linear laser transmitter, or the point-like laser device produces the device of linear laser effect by other modes.
Described plane induction region is characterized in that, the level that plane surface is enough guarantees can not form laser optical path in the plane when laser beam plane and induction region plane parallel are pressed close to and hinders.
Described linear laser generating means is characterized in that, when using a plurality of generating device of laser, need make line-like laser beam flux that each device launched in same plane.
The described apparatus and method that produce touch-sensitive light spots in the plane, it is characterized in that, by many group linear laser generating meanss are set at the outside, plane diverse location, the pairing position of each object can both produce hot spot when can guarantee a plurality of objects simultaneously near the plane induction region, and can can't not shone by laser and can't form hot spot in the relevant position owing to object blocks certain object that makes wherein mutually.
The described apparatus and method that produce touch-sensitive light spots in the plane, it is characterized in that, because linear laser may exist photocentre position light stronger, and with the photocentre be center of circle ambient light the brightness meeting successively slightly a little less than, and block the far and near different formed hot spot brightness of object distance generating device of laser and have difference, when the generating device of laser position is set, need Luminance Distribution according to the plane glazing, make when all positions form hot spot on the induction planes, the hot spot brightness ratio is than homogeneous as far as possible.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is that the present invention cooperates the photoelectricity electronic whiteboard to form the synoptic diagram of touch-screen.
Embodiment
Shown in figure (1), on a rectangle blank, a frame is set, on 4 angles of frame 4 linear laser generating meanss are set respectively.Adjust laser height, make 4 laser instrument institute emitted light beams plane that coexists.And try one's best and be parallel to the blank plane in this plane, makes laser form hot spot by direct irradiation on the plate face.When using pen or finger to indicate on blank, the place that nib or finger tip touch blank can produce a speck.So will five hot spots on the plate face if touch the plate face with five fingers simultaneously.At this moment, the effect of using finger or nib touch pad face can produce indicating effect just as using a laser pointer indicator.
Another application of the present invention is exactly to cooperate the photoelectric technology electronic whiteboard shown in figure (2), by the present invention, directly by conventional pen or finger, on screen, produce hot spot, can substitute the light pen of photoelectricity electronic whiteboard, thereby realize the effect of touch-screen.
