Description
Technical field
The present invention relates to a kind of electric whiteboard systems for classroom teaching evaluation, belong to applied teaching equipment and technology neck
Domain.
Background technology
Currently there are for teaching electronic whiteboard too unification, although electronic writing can be realized,
When the mechanical sense with font when in teaching, shown on electronic whiteboard is too heavy.Such as when teacher is carrying out Chinese language word religion
Class hour, the word that teacher writes will embody the essence of Chinese calligraphy, and one stroke to the left and another to the right wants thick and heavy strong, and the pause and transition in rhythm or melody sense of the vigour of style in writing is apparent, and
It is not the single stroke that common electronic whiteboard is showed, good writing displaying could be to student as writing model.
Secondly, in the teaching skill of the new and old teacher of each institution of higher education and the classroom teaching skill training of normal student, writing on the blackboard
In aesthetics, writing on the blackboard capability evaluation problem, the stroke of writing on the blackboard, firmly thickness, firmly variation of size etc. is all embodied in teacher's
Teaching skill horizontal upper.
But in terms of current electronic whiteboard only resides within teaching character presentation, and the aesthetics of font is had ignored, assessed
Suffer from the limitation of ordinary electronic blank so that the writing on the blackboard form of every teacher all reaches unanimity, without identification.
Utility model content

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment belongs to the scope of protection of the invention.
- 2 are please referred to Fig.1, is a kind of electric whiteboard system for classroom teaching evaluation, it is included with pressure sensitive
Project mutual capacitance type capacitance plate electronic whiteboard and the matching bionic white board marker used；
As shown in Figure 1：The capacitance screen surfaces of the electronic whiteboard enclose one layer of Trackpad 1, in 5 He of inductive layer of capacitance plate
One layer of deformation knot being made of dielectric spring layer 7, upper rise structure sheaf 6 and lower elevated structure layer 8 is added between driving layer 9
Structure, upper rise structure sheaf 6 and lower elevated structure layer 8 are uniformly distributed successively along dielectric spring layer about 7, in dielectric spring layer 7
Gather one layer of net structure 3 for carrying capacitance, and capacitance is uniformly arranged along the X-axis Y-axis of dielectric spring layer 7, and capacitance is arranged tighter
Close, the screen resolution of electronic whiteboard is also higher, and the depth of the stroke color identified is also finer and smoother；The inductive layer 5
On inductive layer connector 2 with driving layer 9 on driving layer connector 4 be connected with each other, existed by bionic white board marker nib
The contact coordinate of screen is oriented in contact on screen, so as to show the stroke of writing and shade；
When writer with bionic white board marker when being write on Trackpad 1, when being wield the pen on the screen due to writer draw
The track power crossed is divided into weight, netted with capacitance in dielectric spring layer 7 since dielectric spring layer 7 deforms upon
The distance between structure 3 d can change because of the small elastic deformation of dielectric spring layer 7, and d becomes smaller, and is felt pressure
Screen at capacitance C will become larger, the depth of pen and ink and the linear variation of the size of capacitance, to this, we are by the color of ink marks
100 kinds of grades are divided by the gray level of white to black, the depth of stroke ink marks color can so naturally carried out
It crosses, so as to reach the analogue simulation of stroke writing；When writer, which wields the pen, weight difference, screen can voluntarily experience bionic
The depth of stroke color can be naturally presented to its pressure in white board marker on the screen.
As shown in Fig. 2, the bionic white board marker built Bluetooth module, carrying out wireless connection with electronic whiteboard makes
With including pen body and nib, the nib is writing brush shape, and outer surface covers one layer of conductive nano cloth 14, conductive nano
Cloth 14 is per se with electrostatic, and soft texture, on the screen fluent writing；Pen body afterbody is equipped with the battery for being conveniently replaceable battery
Open hatchcover 10, top is equipped with power lamp 11, colored select button 12 and switch 13 are respectively equipped on penholder.
The electronic whiteboard uses Android system, when writer needs to carry out screen turning to current writing screen content
When page, cls or preservation, it need to only be operated with screen gesture, time of the writer in classroom instruction can be saved.
As shown in Fig. 2, the power lamp 11, which is equipped with green, dotted state and red vulnerability status two ways, with
Just battery is replaced in time.The battery is two section 5V Rechargeable batteries or disposable battery.
Many traditional instruction utility function buttons are added on the penholder of bionic white board marker, such as multiple color
Colored select button 12 so that writer being capable of the desired function of free switching oneself when carrying out traditional instruction；It is intended to realize imitative
Switching of the raw electronic whiteboard pen to font color on electronic whiteboard, bluetooth module is added in bionic white board marker in advance makes
It realizes wireless connection with electronic whiteboard, while to carry out color conversion volume to each color button of bionic white board marker
Journey.
As shown in figure 4, the effect form for the font that existing electronic whiteboard apparatus system is showed, form is poor,
Font stroke does not have thickness, and also without the font vigour of style in writing, the font that font ink marks is presented also without point of the depth, using the present invention is such as
Shown in Fig. 3, the form that font is shown is just more vivid, can reduce the true of writer's writing on the blackboard font to greatest extent
Mark carries out objective effective assessment to the classroom instruction blackboard Using Skill of normal student.
In conclusion compared with the electronic whiteboard on existing market, the present invention has the following advantages：
1）Electronic whiteboard uses pressure sensing type capacitance plate, and wieling the pen for writer can be distinguished while writer's writing line
Dynamics so that writer shows the depth and thickness of pen and ink in classroom instruction when being write on electronic whiteboard；
2）The similar writing brush nib of nib of bionic white board marker, font line can be sketched the contours of in writing as writing brush
The vigour of style in writing of item so that stroke has pause and transition in rhythm or melody sense；
3）Bionic white board marker carries bluetooth module, and by its wireless connection with electronic whiteboard, writer can be voluntarily
Realize the selection to writing font ink marks color；
4）The writing on the blackboard writing that the present invention can be good to instructor reduces, and gives technical capability evaluation person one well
With reference in addition, this system can preserve writing on the blackboard image in real time using Android system so that assessment is more convenient, breaches time sky
Between limitation, make teaching board technical capability evaluation work carry out it is more smooth, realization electronics and IT products and hommization it is organic
With reference to.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
