Core functions of computer electronic whiteboard software

Three-stage interactive design creates an efficient classroom interactive platform

I. Dual-mode intelligent teaching system

(I) Immersive teaching mode

Supports direct import of PPT files to achieve layered editing of original text, pictures, tables and animations. Teachers can use brushes, shapes and other tools to mark key points in real time on the PPT page, freely insert text boxes, mathematical formulas, dynamic charts, and provide 20+ animation effect settings to improve the efficiency of complex courseware production by 30%.

(II) Global annotation mode

With cross-software compatibility, annotations can be enabled in any interface such as web pages, videos or third-party software, supporting real-time annotations, arrow guidance, highlighting and other operations, and the annotation content is automatically synchronized to the teaching screen. The annotation results can be shared to the student tablet or remote conference end with one click, supporting historical annotation backtracking and page positioning, making classroom interaction more targeted.

II. Professional-level tool matrix

(I) Diversified pen tools

Provide 6 pen tools to meet different teaching needs:

Pencil and chalk tools support three types of line shapes: solid line, dotted line, and wavy line. The thickness of the handwriting can be adjusted intelligently according to the pressure sensitivity. It is suitable for scenarios such as formula derivation and key markup.

The brush and marker are equipped with a 128-color color picker and transparency adjustment function. The edge blur effect simulates real brushstrokes, which is suitable for illustration drawing and mind map creation.

The stamp pen has built-in 20+ reward stamps such as medals, stars, smiley faces, etc., which can be quickly inserted by clicking, for instant classroom motivation and improving student participation.

The texture pen provides texture brushstrokes such as wood grain, cloth grain, and stone grain, and supports custom imported image textures. It is suitable for art course creation and scenario-based teaching.

(II) Intelligent erasing system

Provide three-level erasing mode:

Local erasing supports precise erasing of specified handwriting, and local clearing can be achieved through gesture circle selection.

Erase the board only clears the annotations on the current page, leaving the original courseware unaffected.

Erase the screen can clear all writing traces on the screen with one click, quickly resetting the teaching scene.

(III) Teaching auxiliary tools

Integrate a variety of practical tools to improve classroom demonstration effects:

Dynamic demonstration tools include searchlights to focus on key areas, screen zooming to lock details, screenshot tools to collect materials in real time, and support video recording to generate micro-class clips.

The mathematics teaching aid library has built-in rulers, triangles, protractors, compasses, etc., which can be dragged to generate standard geometric figures and display angle values to achieve visual formula derivation.

III. Multimedia interactive innovation

(I) Direct camera connection function

You can directly call the device camera without third-party software, shoot the experimental process or student works, and directly circle and explain in the dynamic video screen. It supports static capture and save to the courseware. It provides a multi-image comparison mode that can display 2-4 pictures at the same time, supports synchronous zooming and moving comparison, and is suitable for teaching scenarios such as biological slice observation and art appreciation.

(II) Convenient sharing system

Supports QR code scanning and sharing of courseware. Users can download the current courseware including annotations in PDF, image or link format by scanning the QR code. At the same time, it has the cloud synchronization storage function, automatically saves the teaching process to the account cloud, and manages by course or date, so as to achieve seamless transfer across devices.

IV. Humanized interactive design

(I) Three-stage operation interface

Adopts clear functional partition design:

The left menu bar integrates courseware management, account center, system settings and other functions, and supports operations such as creating, importing, and saving courseware.

The middle tool area provides common brush quick switching, eraser tool and undo/redo button, supports 100-step historical backtracking, and is convenient for teachers to operate flexibly.

The right page bar displays multi-page courseware thumbnails, supports quick operations such as dragging and dropping page order, creating a new blank page, and copying the current page, which is convenient for courseware structure management.

(II) Cross-platform adaptability

Compatible with Windows 10 + and macOS 12 + systems, compatible with mainstream brand touch screens and digital tablets, the handwriting pen pressure sensitivity accuracy reaches 4096 levels, bringing a delicate writing experience. No need to install third-party plug-ins, the installation package is less than 200MB, and it can run smoothly on old devices, reducing the cost of hardware upgrades.

Core value:

Through dual-mode switching, full-scene tool chain and intelligent interactive design, the electronic whiteboard is transformed into a teaching platform that integrates courseware production, classroom interaction, and achievement precipitation, helping teachers to achieve teaching upgrades from content display to deep interaction, and building an efficient and convenient digital classroom ecosystem.
