Magnetic Pen for IR Touch: How It Works on Interactive Whiteboards

A Complete Guide to IR Touch Technology in Qtenboard Interactive Whiteboards

Interactive whiteboards are now widely used in classrooms, training centers, and office meeting rooms. Among the many touch technologies available, IR (infrared) touch remains one of the most popular choices for large-format displays. One common accessory users often search for is the magnetic pen for IR touch.

In this article, we explain what a magnetic pen for IR touch is, how it works, where it is commonly used, and why it plays an important role in Qtenboard interactive whiteboards.

What Is a Magnetic Pen for IR Touch?

A magnetic pen for IR touch is a passive writing tool designed specifically for displays that use infrared touch technology. Unlike active stylus pens, it does not require batteries, Bluetooth pairing, or charging.

Instead, the pen works by physically blocking infrared light on the IR touch frame. When the pen touches the screen surface, the IR sensors detect the interruption and accurately determine the touch position.

Most magnetic pens are designed with:

• A solid pen tip for precise writing
• A durable body for long-term use
• Magnetic attachment, allowing the pen to stick to the screen frame for easy storage

This makes magnetic pens especially suitable for interactive whiteboards used in classrooms and conference rooms.

How IR Touch Technology Detects the Magnetic Pen

IR touch technology works by placing infrared transmitters and receivers around the edges of the display. These components form an invisible grid of infrared light across the screen surface.

When a magnetic pen, finger, or other object touches the screen:

• The infrared beams are interrupted
• The system calculates the exact X and Y coordinates
• The touch signal is sent to the display system in real time

Because this method relies on physical interruption rather than electrical conductivity, IR touch supports:

• Magnetic pens
• Finger touch
• Gloves
• Multiple touch points at the same time

This is why IR touch technology is widely used in large-size interactive whiteboards and interactive flat panels.

Magnetic Pen vs Finger Touch on IR Interactive Whiteboards

Both magnetic pens and finger touch work well on IR touch displays, but they serve different purposes.

• Higher writing accuracy
• Better control for handwriting and drawing
• Reduced accidental touches during writing
• Ideal for teaching, presentations, and annotations

• Faster navigation
• Convenient for simple operations
• Suitable for zooming, moving objects, and page switching

In real-world usage, most classrooms and meeting rooms combine both methods: finger touch for navigation and a magnetic pen for writing.

Where Is Magnetic Pen for IR Touch Commonly Used?

Magnetic pens for IR touch are widely used in scenarios where accuracy and stability matter:

• Interactive whiteboards for classrooms
• Smart teaching boards in K-12 education
• University lecture halls
• Corporate meeting rooms
• Training centers and presentation spaces

In these environments, users often write continuously for long periods. A magnetic pen provides a more natural and comfortable writing experience compared to finger input.

Why Qtenboard Uses Magnetic Pen with IR Touch Technology

Qtenboard interactive whiteboards are designed to deliver stable performance, precise writing, and long-term reliability. For this reason, Qtenboard adopts high-precision IR touch technology combined with magnetic pen support.

Key advantages include:

• Accurate touch detection across large screen sizes
• Support for magnetic pen, finger touch, and multi-touch
• Low writing latency for smooth handwriting
• Magnetic pen attachment for easy storage and classroom management

By optimizing both hardware and touch algorithms, Qtenboard ensures that writing and interaction remain responsive and consistent in daily use.

Magnetic Pen for IR Touch in Qtenboard Interactive Whiteboards

Qtenboard interactive whiteboards are available in sizes ranging from 55 to 110 inches, making them suitable for both classrooms and conference rooms. The IR touch system supports multiple touch points, enabling collaboration, group interaction, and real-time annotation.

Combined with built-in whiteboard software, screen sharing, and annotation tools, the magnetic pen becomes a practical and reliable tool for:

• Teaching and lesson delivery
• Meeting notes and brainstorming
• Training sessions and presentations

Qtenboard focuses on providing a complete interactive solution rather than just a display, ensuring ease of use for teachers, presenters, and corporate users.
