Description

The multiple point touching control desk

Technical field

The utility model relates to a kind of computer display device, particularly a kind of touching computer display device.

Background technology

For a long time, people only are accustomed to controlling the computer picture with mouse always, make Multi-Touch multipoint mode Touch Screen technology can't obtain complete utilization in sci-tech product.With user's angle, utilize finger directly at the enterprising line operate of screen, more accurate more than what use mouse to come in theory.Though this can allow the user expend more action and muscle power, however, more enjoyment can in controlling process, be obtained.In addition, various 3D images or image processing software interface are arranged at present, and design is too in complexity in the process of controlling, and must arrange in pairs or groups mouse and keyboard use in the lump, even many modes of operation also are dependent on intuition and experience, could obtain best control mode.Therefore,, replace present employed keyboard (button), mouse, will further embody the future trend of hommization operating and controlling interface if use Multi-Touch multi-point touch control type interfacing.Multiplex touch control is multiple spot on same display interface or multi-user's interactive mode of operation, abandoned the single-point mode of operation of keyboard, mouse.Multi-point touch is divided into two aspects in actual applications, and first main control chip can be gathered multi-point signal simultaneously, and it two is the meanings that can judge every road finger touch signal, in other words can provide the gesture identification function for the user exactly.The user can carry out single-point touches and clicks, double-click, translation, pushes, rolls and different gesture touch screen such as rotation by both hands, realization moves up and down, behind the area that click is wanted to understand, can with this area practically figure zoom in or out, can carry out simultaneously solid and overturn, help understanding the correlated characteristic (literal, video recording, picture, defend information such as sheet, three-dimensional simulation) of object.Not just point, write, by so simple; Also available singly the finger by pressure-controlled, or strut, draw in picture with two fingers, so that reach the purpose of convergent-divergent image, control as long as be apt to the hands can follow one's bent.

The utility model content

The purpose of this utility model provides a kind of multiple point touching control desk, and the utility model has solved the problem that present touch display device needs keyboard and mouse to be used.

Multiple point touching control desk of the present utility model, comprise desktop and be installed in trunk table body below the desktop, the saturating screen of the clear glass back of the body is installed on the table, infrared laser transmitter, infrared ray high-speed camera, the varifocal wide-angle projector of high lumen are arranged in the trunk table body and contain the server of RCB component high-speed video capture card, infrared laser transmitter, infrared ray high-speed camera, the varifocal wide-angle projector of high lumen connect the server that contains RCB component high-speed video capture card respectively.

Multiple point touching control desk of the present utility model has following technical characterstic:

1, multiplex touch control is multiple spot on same display interface or multi-user's interactive mode of operation, has abandoned the single-point mode of operation of keyboard, mouse.

2, multi-point touch is divided into two aspects in actual applications, and first main control chip can be gathered multi-point signal simultaneously, and it two is the meanings that can judge every road finger touch signal, in other words can provide the gesture identification function for the user exactly.

3, the user can carry out single-point touches and clicks, double-click, translation, pushes, rolls and different gesture touch screen such as rotation by both hands, realization moves up and down, behind the area that click is wanted to understand, can with this area practically figure zoom in or out, can carry out simultaneously solid and overturn, help understanding the correlated characteristic (literal, video recording, picture, defend information such as sheet, three-dimensional simulation) of object.

4, simultaneously not just point, write, by so simple; Also available singly the finger by pressure-controlled, or strut, draw in picture with two fingers, so that reach the purpose of convergent-divergent image, control as long as be apt to the hands can follow one's bent.

5, can carry out remote assistance to client computer, possess and connect various digital equipments, possess function such as video matrix.

6, according to customer demand, customized various touch software multimedia systems, can with MAP INFO MAP GIS professional GIS graphics software such as GOOGLE EARTH be used.

Multiple point touching control desk of the present utility model, utilize Infrared to squeeze on the transparent glass steel flat board, and the tram is grasped in the reflection that utilizes light to run into the finger generation, can be integrated in projector or the liquid crystal panel, and in conjunction with identification techniques such as gesture, Freehandhand-drawing tracks, as in, large scale interactive teaching, mouse action, Games controls and presentation function.

Embodiment

Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.

Consult Fig. 1-Fig. 3, the multiple point touching control desk, comprise desktop 6 and be installed in trunk table body 7 below the desktop 6, the saturating screen 1 of the clear glass back of the body is installed on desktop 6, infrared laser transmitter 2, infrared ray high-speed camera 3, the varifocal wide-angle projector 4 of high lumen are arranged in trunk table body 7 and contain the server 5 of RCB component high-speed video capture card, infrared laser transmitter 2, infrared ray high-speed camera 3, the varifocal wide-angle projector 4 of high lumen connect the server 5 that contains RCB component high-speed video capture card respectively.Have 3, four infrared ray high-speed cameras 3 of four infrared ray high-speed cameras to lay respectively at trunk table body 7 interior four bights, an infrared laser transmitter 2 is positioned at the top of trunk table body 7.Wheel 8 is arranged at the bottom of trunk table body 7.By the saturating screen 1 emission infrared spectrum of the clear glass back of the body of infrared laser transmitter 2 on desktop 6, when artificial interactive operation, human finger meeting reflection absorption ftir spectroscopy, infrared light after the reflection triggers induction infrared ray high-speed camera 3, after the RGB component high-speed video capture card acquired signal of the server 5 of the vision signal that infrared ray high-speed camera 3 is triggered through containing RCB component high-speed video capture card, software systems (the high-speed video acquisition module that contains the server 5 of RCB component high-speed video capture card in process, the video pictures pretreatment module, move pre-detecting module, shape is an identification module, touch the curtain playout software, many people are intersected interactive touch menu module, a touch curtain correction software) after the analysis, finish interactive operation in conjunction with the varifocal wide-angle projector 4 of high lumen, and the demonstration of various trade informations.
