Two touch characteristics
Touch technology non-contact Infrared touch technology uses built-in touch technology and does not accept external contacts for two-point writing and four-point or more touch
When the touch screen is connected to external devices such as computers, there is no need to install a driver
Touch finger pen, or any other non-touch screen Transparent objects
Continuous response speed, continuous nodding
Nodding response time, continuous response time
Computer response switching channel, the system automatically identifies internal and external touch channels
With soft central control function through the screen Menu touch control In any signal channel, image mode channel switching, channel switching, brightness, volume, contrast adjustment can be realized through the screen touch menu. That is, it can be switched to peripherals such as desktop computers or notebooks in real time for the teacher's convenience.

The device has anti-static and anti-interference functions
The touch screen of the device has an anti-blocking function, and the touch receiver is Single point or at least one point of multi-point infrared emission point can still be written normally after being blocked
The metal surface of the device casing must meet the requirements of salt spray test level or above
Six software features
The writing and erasing function provides a hard pen Highlight pens and soft pens can be used for writing, providing point erasure of large, medium and small areas and circle erasing of objects
The screen roaming function allows the screen writing range to be infinitely extended, providing unlimited electronic blackboard writing annotations for teaching. The layout
supports two-point writing operations at the same time, and supports the zoom, rotation and movement functions of picture, audio and video graphic lines.
Provides the drawing function of commonly used graphics and the automatic recognition function of hand-drawn graphics, and provides the color and picture filling function of closed graphics.

The above list of functions can be implemented in both simple mode and desktop mode. The standard mode toolbar is fixed at the bottom of the screen, all functions can be accessed quickly, and the layout of function icons can be switched left or right. The simple mode toolbar can be docked arbitrarily and can automatically switch between horizontal and vertical modes. The desktop mode toolbar provides hard pen and highlighter pens for annotation under the desktop. It can make transparent annotations and screenshots of any application. It can take full-screen or partial screenshots, and it can also page up and down the presentation.
