Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of formula multimedia presentation system of writing in one's own hand, to realize dustlessization demonstration and teaching, facilitate the personnel's such as vast teacher, conference presentation advantage.
For achieving the above object, the technical solution used in the present invention is:
Write in one's own hand a formula multimedia presentation system, comprise coordinate setting module, interface module and coordinate transferring;
Described coordinate setting module, converts coordinate data to personal letter track;
Described interface module, the coordinate data that above-mentioned coordinate setting module is generated is converted to the coordinate information that unified computer can be identified;
Described coordinate transferring, the coordinate information by after above-mentioned interface module conversion, is converted to the control information of computing machine and generates in real time dynamic Grid Track figure, thereby complete writing of current screen.
According to a preferred embodiment of the invention, described coordinate setting module, utilizes infrared positioning equipment directly to define the coordinate in presentation screen, in the process of writing, because blocking ultrared reception, produces coordinate parameters with personal letter.
According to a preferred embodiment of the invention, described coordinate setting module, for the frame place at screen is provided with infrared emission matrix, horizontal and vertical emission matrix and the receiving matrix of arranging respectively, when the barriers such as finger or pen stop in screen surface, can block the reception of a part of infrared beam, thereby identify and generate coordinate parameters by coordinate generation module.
According to a preferred embodiment of the invention, described coordinate setting module, utilizes touch apparatus as writing implement, in hand or touch-screen writing implement writing process, can produce corresponding coordinate parameters.
According to a preferred embodiment of the invention, described coordinate setting module, adopts and accelerates sensing apparatus, and the mobile meeting generation flat transverse of equipment and longitudinally continuous variable quantity, form deformation trace generation character or figure.
According to a preferred embodiment of the invention, described interface module, obtains coordinate setting module parameter, and unification converts the coordinate parameters that computing machine can be identified to, and passes to host computer by USB interface, bluetooth equipment or Zigdee technology.
According to a preferred embodiment of the invention, described coordinate setting module is communicated by letter by 485 communication interface standards with interface module.
Technical scheme of the present invention has following beneficial effect:
Technical scheme of the present invention, by described coordinate setting module, the action of outside writing pencil or hand is converted to digital coordinates, and and by interface module and coordinate transferring, be converted to image path and show on screen, thereby replaced the writing on the blackboard of existing teaching use, change existing multimedia system and cannot normally take down notes, mark, take passages, drill the defects such as plate, reached and realized dustlessization demonstration and teaching, facilitate the personnel's such as vast teacher, conference presentation object, the health hazard of having avoided the dust because using chalk to produce to cause.Change traditional writing on the blackboard demonstration for the consumption in the artificial one-tenth muscle power of demonstration and the harm in health.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the write in one's own hand formula multimedia presentation system structural representation described in the embodiment of the present invention.
By reference to the accompanying drawings, in the embodiment of the present invention, Reference numeral is as follows:
1-infrared emission matrix; 2-screen.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of formula multimedia presentation system of writing in one's own hand, comprises coordinate setting module, interface module and coordinate transferring; Coordinate setting module, converts coordinate data to personal letter track; Interface module, the coordinate data that above-mentioned coordinate setting module is generated is converted to the coordinate information that unified computer can be identified; Coordinate transferring, the coordinate information by after above-mentioned interface module conversion, is converted to the control information of computing machine and generates in real time dynamic Grid Track figure, thereby complete writing of current screen.
Wherein, coordinate setting module, utilizes infrared positioning equipment directly to define the coordinate in presentation screen, in the process of writing, because blocking ultrared reception, produces coordinate parameters with personal letter.
Coordinate setting module, for the frame place at screen is provided with infrared emission matrix, horizontal and vertical emission matrix and the receiving matrix of arranging respectively, when the barriers such as finger or pen stop in screen surface, can block the reception of a part of infrared beam, thereby identify and generate coordinate parameters by coordinate generation module.
Coordinate setting module, utilizes touch apparatus as writing implement, in hand or touch-screen writing implement writing process, can produce corresponding coordinate parameters.
Coordinate setting module, adopts and accelerates sensing apparatus, and the mobile meeting generation flat transverse of equipment and longitudinally continuous variable quantity, form deformation trace generation character or figure.
Interface module, obtains coordinate setting module parameter, and unification converts the coordinate parameters that computing machine can be identified to, and passes to host computer by USB interface, bluetooth equipment or Zigdee technology.
Coordinate setting module is communicated by letter by 485 communication interface standards with interface module.
Coordinate setting module: can be served as by plurality of devices.As infrared ray, acceleration sensing apparatus and touch apparatus etc.,
The frame place of screen is provided with infrared emission matrix, requires matrix resolution enough high, horizontal and vertical emission matrix and the receiving matrix of arranging respectively.When the barriers such as finger or pen stop in screen surface, can block the reception of a part of infrared beam, thereby identify and generate coordinate parameters by coordinate generation module.
This coordinate parameters not necessarily can meet the coordinate parameters that computer shows, by 485 signal transmission lines, coordinate parameters is passed to unified coordinate interface module and carry out coordinate transform, the coordinate after conversion passes to host computer (computer) by USB interface, bluetooth equipment or Zigdee technology.
