Qtenboard 9679 Chip Interactive Whiteboard – Smart Eraser Functions

2025-11-24

The Qtenboard 9679 chip interactive whiteboard offers a smart and flexible erasing experience, designed to complement its pen features and make content management intuitive and efficient. Users can quickly remove mistakes, clear annotations, or reset the board in educational, corporate, and creative settings.

1. Eraser Types

  • Standard Eraser: Activate the standard eraser by tapping the bottom eraser button. It removes specific strokes with precision, making it perfect for correcting individual words, numbers, or small drawings.
  • Circle Eraser: Also accessed via the bottom eraser button, the circle eraser removes content within a defined circular area. This is useful for erasing a cluster of annotations without affecting surrounding content.
  • Full-Screen Clear: Tap the full-screen clear button at the bottom to instantly remove all content on the board. This function is ideal for starting a new lesson, meeting, or brainstorming session quickly.
  • Palm Erase: Palm erase allows users to naturally wipe away content by using their hand. The whiteboard automatically adjusts the eraser size based on the touch area, simulating the feel of a traditional whiteboard eraser and enabling intuitive broad content removal.

2. Switching Eraser Modes

Switching between standard and circle erasers is simple: Go to Settings → Writing Settings → Eraser Mode, and tap to select your preferred mode.

3. Practical Applications

  • Education: Teachers can correct mistakes or erase student work quickly without interrupting the lesson flow. Palm erase allows broad erasing with natural hand gestures.
  • Corporate Meetings: Presenters can efficiently modify diagrams, notes, or annotations during brainstorming sessions. Full-screen clear ensures a fresh slate for the next topic.
  • Creative Design: Designers can refine sketches or illustrations with precision, switching between targeted and broad erase modes as needed.

By offering multiple eraser modes and intuitive controls, the Qtenboard 9679 interactive whiteboard ensures a seamless and efficient content management experience, making it a reliable tool for classrooms, offices, and creative environments alike.
