FAQ

• Can the reading pen download other resources or audio files?
  Yes. Our pens support content updates via USB or Wi-Fi (optional). Users can download audio resources provided by their specific publishers. For our B2B partners, we provide a proprietary tool to manage and update audio libraries seamlessly.
• What can I buy from Dimdu besides the reading pen?
  We provide a complete interactive learning ecosystem, including Bluetooth-enabled pens, AI-powered speech recognition pens, recordable stickers, and custom-printed OID books. We are a one-stop-shop for educational publishers.
• What makes OID 3.0 technology better than older versions?
  OID 3.0 offers significantly higher recognition density and faster response times (<0.1s). It supports a wider range of colors and textures, meaning it won't interfere with the book's original artwork. It also has better error correction, ensuring the pen reads accurately even at different angles.
• What is the working principle of the OID reading pen?
  The OID (Optical Identification) pen works by using a high-speed micro-camera at the pen tip to scan invisible dot codes printed on the paper. These codes are mapped to specific audio files stored in the pen's memory. When the pen touches the code, it instantly triggers the Sonix chipset to decode and play the corresponding sound, creating an interactive "point-and-read" experience.
• How does the OID pen achieve intelligent tutoring?
  Through our proprietary software that includes: • Adaptive learning paths based on user performance • Pronunciation correction using speech recognition • Progress reports and learning analytics • Interactive feedback and encouragement system
