  In modern classrooms and meeting rooms, interactive tablets have become important tools for communication and collaboration. However, a common and annoying problem that users often encounter is accidental touch input: when writing with a stylus, the screen may record the contact of the palm, wrist, elbow or other parts of the body, resulting in messy lines and disrupting the workflow.     To address this issue, Qunmao has developed a powerful palm accidental touch elimination function in its Qtenboard interactive tablet series. How will this considerate feature improve the writing experience     1. Precise pen recognition and automatic rejection of unnecessary touches   Qtenboard adopts an advanced touch recognition algorithm, which can distinguish between intentional stylus input and unintentional hand or arm contact. When you write with a pen, the system precisely recognizes the pen signal and ignores the touch on your palm, wrist, elbow or shoulder. This effectively avoids unnecessary lines and incorrect input on the screen.         2. Place your hands naturally without hovering   Without the function of preventing accidental palm touch, users often have to hover their hands above the screen when writing - this posture is neither natural nor easy to cause fatigue. With Qtenboard, you can naturally place your hand on the screen, just like writing on paper. This makes writing more comfortable, stable and efficient.         3. Smooth multi-user collaboration   In group Settings, multiple people can interact with the screen simultaneously. Qtenboard supports multi-pen input and multi-touch input. Its anti-accidental palm touch function ensures that each user's writing remains neat and undisturbed - even if both hands overlap or touch the screen simultaneously. This is highly suitable for brainstorming, co-creation and real-time collaboration.         4. Designed for diverse scenarios - a truly user-centered solution   Whether it's teachers giving lessons, students taking notes, business teams presenting ideas, or children using interactive apps, Qtenboard's palm accidental touch rejection function can provide a smooth and barrier-free experience. This feature reflects QUNMAO's commitment as a source manufacturer to thoughtful design and precise engineering.         Conclusion   Accidental palm touch is not merely a technical detail; it represents a significant upgrade in user experience. With the Qtenboard interactive tablet, users can write freely, collaborate seamlessly, focus on content without distractions. This is a wise choice for creating smarter classrooms and meeting rooms.

With the rapid development of artificial intelligence and digital technology, art education is also undergoing a profound change. Traditional brushes and paper are being replaced by a more flexible, environmentally friendly and interactive tool - digital canvas. As an important part of the smart classroom, digital canvas is inspiring students' unprecedented creative enthusiasm and imagination.   1. Say Goodbye To Constraints And Let Creativity Grow Freely   Traditional art classrooms are often limited by materials, space and time, while digital canvas allows students to express their creativity anytime and anywhere through a high-definition touch screen. No more correction fluid is needed, no more worrying about using the wrong color, just touch the screen to easily modify, enlarge and reconstruct. This highly free creative experience greatly encourages students to dare to try and dare to break through.   2. Multimedia integration, expanding the form of expression   Digital canvas not only supports painting, but also can integrate animation, video, sound and other elements to help students create richer and more three-dimensional works of art. They can add music to a painting, design actions for characters, and even create interactive content to fully stimulate sensory and mental participation.   3. Instant sharing and interaction to promote learning and communication   Relying on Internet technology, students' works can be shared in real time on the class screen, teacher platform, and even social media. This "creating and displaying" method makes the classroom more open and enhances students' sense of accomplishment and self-confidence. At the same time, teachers can also make personalized comments and guidance based on students' works to improve teaching efficiency.   4. Cultivate digital art literacy and connect future professional skills   Children growing up in the digital age not only need traditional art knowledge, but also need to master digital creation tools. Through the training of digital canvas, students gradually learn to use graphic software, understand image composition, and master creative expression skills. These abilities will lay a solid foundation for their future entry into creative industries such as digital design, animation production, and game development.
