The Huawei IdeaHub B2 (and the S2) provides a natural and intuitive writing experience with three distinct erasing modes:

Gesture/Palm Erase: Users can simply use the palm of their hand or the side of their fist to erase large areas, mimicking a traditional blackboard experience.

Selective Erase (Circle Erase): Users can draw a circle around a specific piece of text or a drawing to select and delete only that portion.

One-Tap Clear (Clear All): A dedicated button on the whiteboard toolbar that allows the user to clear the entire canvas instantly.

This combination provides a balance between high-precision editing and rapid cleaning of the board.
