[embodiment]
See also illustrated in figures 1 and 2ly, embodiment of the present utility model is described in detail.
A kind of image multi-point interactive device of supporting touch and infrared pen simultaneously, comprise a projection screen 1, show two among the infrared laser 2(figure of a plurality of yi word patterns), one infrared pen 3, one master controller 4, the computing machine 6 that one projector 5 and is connected with projector 5 with described master controller 4 respectively, described master controller 4 is provided with first infrared lens 41 and second infrared lens 42, be equipped with the narrow band pass filter (not shown) of infrared light on described first infrared lens 41 and second infrared lens 42, and the infrared light wavelength that sees through of the narrow band pass filter of first infrared lens 41 is different from the infrared light wavelength that the narrow band pass filter of second infrared lens 42 sees through; Described a plurality of infrared laser 2 all is located at projection screen 1 top edges, and the light that sends of described infrared laser 2 is parallel with described projection screen 1; Described master controller 4 and projector 5 all are located at the place ahead of described projection screen 1, and described first infrared lens 41 and second infrared lens 42 be not in the drop shadow spread of described projector 5, and described projector 5 is not in the range of receiving of described first infrared lens 41 and second infrared lens 42.The quantity of described infrared laser 2 can also be three, be arranged at respectively projection screen 1 the edge, upper left side, directly over edge and edge, upper right side (not shown).Described master controller 4 is adjusted according to the visible angle of first infrared lens 41 and second infrared lens 42 with the distance of projection screen 1, can see that with first infrared lens 41 and second infrared lens 42 zone is as the criterion more than or equal to the picture-display-region territory on the projection screen 1.Described infrared laser 2 irradiation light are parallel to described projection screen 1, and cover whole viewing area.Described infrared laser 2 can use USB that it is powered or use external power supply to power separately.Described master controller 4 is connected by the usb data line with computing machine 6, and projector 5 and computing machine 6 are connected by video data line, and the image of projection is presented on the projection screen 1.
See also Fig. 3, the nib of described infrared pen 3 is provided with for the bands absorption 31 that absorbs infrared light, and the infrared light wavelength that described bands absorption 31 absorbs equals the infrared light wavelength that described yi word pattern infrared laser sends.
Principle of work of the present utility model is:
When finger or other objects touch the viewing area of projection screens 1, the Xnm wavelength infrared light that infrared laser 2 sends shines finger or other objects, reflect Xnm wavelength infrared light spot and posted first infrared lens, 41 receptions of the narrow band pass filter of Xnm wavelength pass band, by the processing module on the master controller image being carried out the center calculates, catch this infraluminescence point position, and positional information transferred to computing machine, computing machine calculates luminous point in the relative coordinate of projection screen 1 by the resolution mapping relations of position coordinates and computer screen, writes operation thereby realize touching.
When switching to infrared pen 3 and write, infrared pen 3 is outwards launched the infrared light of the circular light spot of Ynm wavelength in writing process, second infrared lens 42 that this infrared light is posted the narrow band pass filter of Ynm wavelength pass band receives Ynm, the infrared laser 2 of emission Xnm wavelength infrared light, be radiated at the nib of infrared pen 3, but absorbed by the absorption band of the absorption Xnm infrared wavelength of nib, the place can not form bright spot in written position, therefore can not cause interference.By the processing module on the master controller image being carried out the center calculates, catch this infraluminescence point position, and positional information transferred to computing machine, computing machine calculates luminous point in the relative coordinate of projection screen by the resolution mapping relations of position coordinates and computer screen, thereby realizes that infrared is write operation.
Carry out touch-control writes when operating in the large scale zone, because projection screen 1 is oversize, the Xnm wavelength infrared light transmission range of infrared laser 2 emission is far away excessively, first infrared lens 41 catch by the infrared ray of finger reflection a little less than, cause writing the reduction of precision and sensitivity.So when needing the application of high precision and sensitivity under the situation at large-size projecting screen, only not good by the finger touch writing effect, use infrared pen instead and write the deficiency that then can remedy finger touch.
Advantage of the present utility model is: by the infrared light spot that first infrared lens sees through the finger reflection is set, second infrared lens is set sees through the infrared light spot that lettering pen sends, thereby realize that compatible infrared pen is write at projection screen with finger simultaneously simultaneously, and tell writing of finger and writing of infrared pen according to the different wave length of infrared light spot, with better function, use convenient handy, simultaneously by infrared nib bands absorption being set, absorb the infrared light of the infrared laser of finger reflection, avoid the infrared light of infrared pen reflective infrared laser instrument when sending infrared light, reduced interference and misoperation.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
