9.     Positioning accuracy: less than 0.5mm

10.  The anti-glare design: normal use is possible in direct  sunlight or strong light.

11.  Working environment:Working Temperature:-10℃-45℃,Work humidity: 0~90%:

12.  A new generation of intelligent recognition:

large objects (such as palm,

books, erasers, etc.) blocking infrared tube will not affect normal operation (writing, gestures to zoom, eraser, etc.).

13.  Super anti-death point, anti-dust, anti-obstructions, even if the whole border is blocked, normal writing will not be affected.

14.  Provides hardware fault detection, rapid fault location determination.

15.  Firmware upgrading: The firmware upgrade program supports hardware updating remotely via USB in a smart and fast way.

2) Software function:

1. Gesture recognition: Support Windows, Android, MAC gestures, enabling zoom, rotate; no need to click any buttons or shortcuts in the software interface, you can  achieve writing, roaming and erasable gestures (gesture recognition provide patent certificate);

2.    Screen Hold function: a key lock, setting to open or close the touch function, prevent misuse by software directly. (Provide the patent certificate.

3. PPT application: work seamlessly with PPT software, during PPT playback, you can achieve directly PPT flip, labeling and erasing through software shortcuts.

4. The pen functions: to provide pencils, soft pencil, brush, texture pen, objects, pens, etc. 8 kinds of pens and offer multi types of lines, line ends, thickness, color, contrasts and other property settings.

5. The penwipe function: provides object rub, dot rub and scratch brush, to achieve different objects erases

6. Graphic plotting: for fast graphics rendering, including linear, rectangular, oval, round, triangular, pentagonal, five-pointed star-shaped, hexagonal, diamond, arrow, double arrow; cubes, cylinders, cones, etc. user-friendly graphical tool to quickly create standard graphics. Vertices of drawn graphics can be edited, and graphics pattern filling, moving and rotating can be realized.

7. Auxiliary tools: magnifying mirror, ruler, compasses, set-square, protractor, screen recording, video recording, video booth, fill bucket, searchlight, cover screen, camera, randomly getting a number and other commonly used tools, and various mathematically aiding drawing tools.

 8. Page function: can provide white pages, blackboard pages, green pages, transparent pages, picture pages, screen pages, can arbitrarily change the page background according to teaching needs

9. Transparent Page:  to achieve seamless handover between handwriting and mouse. On the same page, computer operation, handwriting and labeling can be achieved together.

10.  Picture Pages: Provide swastika grid, sheet music, Piano, four-line three-grid, English letters and other discipline page.

11. Page operation: support page zoom, roaming, roaming return, the whole page clear, page flip, etc., the roaming function support infinite amplification and moving for the writing page.

12. Direct calling external camera video; and the number of projectors (high shot instrument), with quasi-camera interface perfect combination of video booth, a key call.

13. Reading function (In win7 system, support Chinese, English, digital reading).

14.  Handwriting recognition, support handwriting directly into printing, and rapid phonetic notation for Chinese characters.

15. Support recording and screen recording. Recording function allows playback of all content written on the        whiteboard, and saving it in a media format; screen recording can record not only writing, but also the whole operation including voice and save the video file in the format of AVI and SWF.

16.  Insert object: insert picture supports PNG / BMP / WMV / JPG / JPEG and other insert, text, audio support MP3 format / WMA / WAV / AAC and other formats, video support AVI / SWF / MP4 / WMV / FLV / mpg insert / 3GP and other formats, such as insert histogram.

17. Compatible operating systems: Windows XP and      above,   LINUX, Mac system, Android. All these OS   support double pen writing.

18. offline lessons preparing; software enables offline use   for teacher preparing lessons conveniently; under        WINDOWS7 operating system and Word, IE browser, PPT, image browser and other applications, multi-touch  function is realized directly without the aid of special  software or interface , such as zoom function which can be achieved directly by hand at any time, you do not have to go first to the menu, which greatly saves time and effort for teachers.

19. Software upgrades: The software offers lifetime free

upgrade service.

20.  Resource Library:

a)     The software comes with various disciplines of teaching resources, including pictures, text, multi disciplinary dynamic resources, and provides custom tools and custom resources. Teachers can implement custom resource conservation, management and calls.

b)     Mathematics teaching support: the math resource repository contains mathematical formulas, function curves, mathematics graphics. Common mathematical formulas include a number of commonly used mathematical formulas which have calculation function,  based on the variable value entered by the user. Function curves contain a number of commonly used functions curves, for example, sine, cosine, quadratic, etc. and according to the definition domain and value domanin of function, display corresponding two-dimensional functions, the user can change the function of the curve, definition domain and value domain and save it to the repository. Function graphs contain some common property graphics, such as  two-dimensional coordinate system, three-dimensional coordinates, sine curve, cosine curve graphics.

c)     physics teaching support: contain slide rheostat, spiral micrometer, micrometer, spring balance, concave lens, lens and such experimental graphics as electric circuit, optics etc.

d)     Chemistry Teaching support: this repository contain conventional chemical reaction equations from junior high schools and high schools and a variety of chemical lab wares, including the commonly used chemical beakers, flasks, funnels, alcohol burner, measuring tube, separating funnel, etc. and also dynamic change of container liquid surface, automatic plane maintainence and random adjustment of liquid surface height.

e)      Language teaching support: Vocabulary library resources in English teaching and reading function. Chinese language teaching including the phonetic features of Chinese characters, Chinese characters stroke order playback function, support Chinese characters reading.

f) Other disciplines Support: teaching resources include geography, history, biology, music and other disciplines.
