OCR & Magic Pen Settings

OCR (Text Recognition) Pen

After enabling OCR, you can select different language types based on your needs.

Provides handwriting-to-text conversion with clean, standard-style fonts.

Magic Pen

Includes a built-in shape recognition library.

Supports automatic detection of drawn shapes (e.g., circles, triangles, arrows) and converts them into standard geometric shapes.

The recognized shapes can be inserted directly into the whiteboard canvas.

OCR Pen Writing Effect

Handwritten text is recognized upon lifting the finger/stylus and converted into neat printed text.

Magic Pen Recognition Insertion Effect

Freehand sketches (shapes/arrows/diagrams) are automatically refined and inserted into the canvas as normalized vector shapes.

Background Settings

The whiteboard supports flexible background customization.
Operation steps:

The whiteboard allows setting custom background colors, as well as grid templates for writing, drawing, and teaching.

Custom background images must be at least 2K resolution, and the aspect ratio must match the screen orientation.

When using landscape mode, you cannot insert a portrait-oriented background image (and vice versa).

This ensures that custom backgrounds display correctly and maintain high visual clarity.
