Mark, and be connected with control chip to feed back motion track；This communication module is for communication link between control chip and external computer
Connecing, this external computer is for responding the instruction of control chip and being projected in proportion by motion track or be shown in target blank.
Described electronics chalk also includes being arranged on the intrinsic battery of pen and/or is arranged on the power supply of case surface and connects
Mouthful.
Described electronics chalk also includes the page turning key being arranged on a body and being connected with control chip.
Described electronics chalk also includes being arranged on this laser diode that is internal and that be connected with control chip of pen and swashing
Light button.
Wherein, described communication module is bluetooth module or WiFi module.
Described target blank is electronic whiteboard, or by the common blank of projector.
Present invention additionally comprises and the data processing method of the above-mentioned same inventive concept of electronics chalk, comprise the following steps (A)
Electronics chalk power-up initializing；(B) communication between control chip and external computer and external computer and target blank is set up
Connect；(C) electronics chalk motion track on target blank is gathered 1.；(D) motion track projected the most in proportion or show
In target blank.
Described data processing method also includes step (E): chalk pattern is switched to chalkboard eraser pattern；(F) again adopt
Set electron chalk motion track on target blank is 2.；(G) by projection or be shown in target blank and 2. covered by motion track
The motion track of lid eliminates the most in proportion.
Further, the motion track gathered in described step (F) 2. does widening treatment.
Beneficial effects of the present invention:
The present invention is compared to conventional multimedia teaching, and electronics chalk can strengthen multimedia interactive, be provided that teaching simultaneously
Need common function, including PPT page turning, electronic teacher pointer, chalk and chalkboard eraser, also reduce the operation easier of multimedia teaching,
Solve the materials of conventional chalk and avoid air pollution.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
Fig. 1 is the theory diagram of electronics chalk of the present invention；
Fig. 2 is the flow chart of electronic powder pen data processing method of the present invention.
Detailed description of the invention
As it is shown in figure 1, be a kind of electronics chalk of the present invention, including a body and be arranged on pen intrinsic control core
Sheet, optical sensor, optical lens module, light emitting diode, communication module；
This light emitting diode is for producing the light irradiated on target blank；Optical lens module is for sending light emitting diode
Light be sent to target blank and lighted and the target whiteboard images being illuminated is sent to optical sensor；This light
Learn induction apparatus to be used for imaging continuously target blank to gather the motion track of a body, and be connected with instead with control chip
Feedback motion track；
This partial traces acquisition principle is consistent with the operation principle of optical mouse, has used for reference optical mouse when moving, its moving rail
Mark will be recorded as the coherent image of one group of high-speed capture by optical sensor, is divided by the special image of electronics chalk body interior
Analysis chip (being equivalent to the control chip of the present invention) analyzing and processing.This control chip is by characteristic point position on these images
Change is analyzed, and judges moving direction and the displacement of electronics chalk, thus completes light target location.Wherein, image
Being to scatter after target blank is by coherent light illumination, can form Space Speckle, what optical sensor shot is exactly the pattern of speckle.
The pattern of speckle depends on illuminated region, so move when electronics chalk, illuminated region is in change, and imaging is out
Speckle pattern is also in translation.The generally detection to speckle pattern translation uses and closes on image addition or subtract each other, and can produce similar poplar
The striped that family name interferes.
The electronics chalk of the present invention can not work independently, and needs an external computer simultaneously worked, above-mentioned communication
Module is exactly for communicating to connect between control chip and external computer, this external computer for respond the instruction of control chip with
And motion track is projected in proportion or is shown in target blank, thus realize chalk scribble function.
Wherein, the communication module of the present embodiment preferably employs bluetooth module, but other can transmit data with compunlcation
Module be also applied for the present invention, such as WiFi module.In like manner, described target blank includes but not limited to electronic whiteboard, or
