Technical Deep Dive

Huawei IdeaHub B2 supports multi-touch whiteboard gestures that let users manipulate digital content naturally. Its intelligent whiteboard documents selection, movement, zooming, and erasing operations. Zoom in enlarges the canvas or chosen content; zoom out reduces its scale and presents a larger working area. Erase removes supported handwriting or annotation content without requiring a physical eraser.

The device detects simultaneous touch positions and interprets their relative movement through the whiteboard interface. The gesture functions complement low-latency handwriting, multiple stroke styles, intelligent text and shape recognition, and local co-authoring. The 25 ms writing-latency specification makes the interface more responsive during meetings and classroom use. Note that zoom in and zoom out are two outcomes of the same category of zoom gesture, but the question deliberately lists them separately. All three provided options are supported capabilities. The correct combined answer is A, B, and C.

During customer solution design, engineers must distinguish native collaboration functions from optional OPS modules, external peripherals and software or conferencing licenses. Display size, room acoustics, source-device capabilities, network conditions and firmware release can all affect practical performance. A model-family feature should not automatically be attributed to every other IdeaHub generation.
