Abstract
The utility model relates to the field of computer, in particular to an input device inputting a handwriting signal and an operation signal to the computer. A remote control electronic whiteboard comprises a projection curtain, an optical signal receiving device employing a short-focus wide-angle lens, a signal processing device, an optical signal emitting device, a fixed bracket, a projection device and a computer. The input device is characterized in that the optical signal receiving device employing the short-focus wide-angle lens is arranged on the inclined upper side of the projection panel by a bracket so as to be used for collecting faculae formed by the laser given out by a laser remote controller on a projection panel; and processing is carried out by the signal processing device to calculate the position coordinate of the faculae on the projection panel. Moreover, the remote control of an electronic whiteboard system is completely realized.
Description
Invention field
The utility model relates to computer realm, is the input media to computing machine input person's handwriting signal and operation signal.
Background technology
Multimedia give lessons more and more popularize now, adopt electronic whiteboard to become the popular at present mode of giving lessons on class.Yet the operation of present blank all can only be limited on the panel, teacher promptly can't control courseware after leaving the dais, though being arranged on the market, a lot of wireless mouses etc. can realize some remote operated functions, but because the location is cumbersome, make rolling mouse more loaded down with trivial details to the operation of assigned address especially, operation is not very convenient; Also have simulation minority keypad functions such as some simple page turners, can only realize operation and indication operations such as some simple page turnings.
Summary of the invention
The purpose of this utility model provides a kind of remote control electric blank, and it has used suitable picture pick-up device and relevant adjusting gear, makes it possible to computer be controlled and various softwares are operated by special laser remote-controlled device.
A kind of remote control electric blank, the light signal receiving, signal processing apparatus, the laser signal transmitter that comprise projection screen, employing wide-angle lens, fixed support and projector equipment and computing machine, it is characterized in that, oblique upper is fixed a signal receiving device that adopts short focus wide-angle lens with support in the middle of projection screen, be used to be captured in the formed hot spot of laser signal transmitter on the projection screen, handle by signal processing apparatus, calculate the position coordinates of light pen luminous point on the projection panel.
On the basis of technique scheme, the utility model also has following further scheme:
Described a kind of remote control electric blank is characterized in that, transmits at a distance by laser remote-controlled device.
Described signal processing apparatus is characterized in that, is connected with computing machine by the USB connecting line.
Described signal receiving device is characterized in that, has adopted and the corresponding filter of laser wavelength that laser remote-controlled device is sent out, and is used for filtering the veiling glare in the environment, reduces the interference of surround lighting to system.
Take after the further step, advantage of the present utility model is further outstanding.The wide-angle lens that adopts is made through special process, can make the distortion of finding a view of camera lens very little, locatees more accurate, simpler, give and to be installed and used the very big convenience of bringing, especially be provided with adopt support fixing after, camera secured in alignment image pickup scope.
Need not each the use and all locate, it is convenient simple that the user is used.
When described computer interface circuit is USB interface, can realize the various facilities that plug and play is brought.
When the camera of described picture pick-up device was provided with optical filter, the part that can filter in the environment was disturbed light, so that the utility model still keeps stable duty in relatively poor environment.
Description of drawings
Accompanying drawing one is a front elevation of the present utility model, and wherein 1-1 is a signal receiving device, and 1-2 is a curtain;
Accompanying drawing two is side views of the present utility model, and wherein 2-1 is a signal receiving device, and 2-2 is a curtain, and 2-3 is laser remote-controlled device, and 2-4 is a laser beam.
Embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:
Projection arrangement is connected with computing machine, and projection arrangement can use prior art.Picture pick-up device uses short burnt wide-angle imaging head, and computing machine can be desktop computer or notebook computer.The front end of described laser remote-controlled device is sent out can emission of lasering beam; When pushing button or can launching the laser facula that is captured by camera during touch-pressure switch.The photosignal that signal receiving device receives converts to can be by the digital signal of Computer Processing, Here it is described signal processing apparatus.Computing machine need be installed corresponding software, and the utility model uses E photoelectron blank drive software.Photoelectric signal process equipment can connect computing machine by the computer interface circuit.When photoelectric signal process equipment connects computing machine by computer interface, can use usb circuit.
Camera and signal are received and treating apparatus places monitor cartridge inside, be installed in the end of support, adjust angle and make camera imagine scope can to comprise view field on the whole blank.Equipment can be connected with computing machine easily by USB interface.
Optical filter is set on the camera lens.The structure of optical filter is equivalent to the optical filtering camera lens that camera is used, and can be enclosed within on the camera, and the effect of optical filter is some variegated light that filter in the environment, can further improve the advantage of bringing, especially antijamming capability of the present utility model.The color of optical filter can be determined according to the color of light that laser instrument sends on the laser remote-controlled device.
