背景技术Background Art
在传统教学中，粉笔和黑板是常见的工具。然而，粉笔产生的粉尘对健康有害，且传统粉笔书写的质感无法在现有电子书写设备上完全再现。为了实现环保和提升教学体验，各类电子书写设备应运而生，但它们在书写手感方面仍然存在不足，难以完全取代粉笔和黑板的组合。目前市场上的电子书写设备多采用压感笔，但这些设备通常成本较高，且在使用过程中容易损坏。另一种方法是利用触控屏的表面声波或光学成像技术来模拟压力感应，但这些技术复杂，难以推广。In traditional teaching, chalk and blackboard are common tools. However, the dust produced by chalk is harmful to health, and the texture of traditional chalk writing cannot be fully reproduced on existing electronic writing devices. In order to achieve environmental protection and improve the teaching experience, various electronic writing devices have emerged, but they still have shortcomings in writing feel and it is difficult to completely replace the combination of chalk and blackboard. Currently, most electronic writing devices on the market use pressure-sensitive pens, but these devices are usually expensive and easily damaged during use. Another method is to use surface acoustic waves or optical imaging technology of touch screens to simulate pressure sensing, but these technologies are complex and difficult to promote.
为了克服上述问题，本发明提出了一种模拟粉笔触感的压感笔尖，采用特殊材料和设计，通过摩擦感和压感反馈模拟传统粉笔的书写质感。In order to overcome the above problems, the present invention proposes a pressure-sensitive pen tip that simulates the touch of chalk, which adopts special materials and design to simulate the writing texture of traditional chalk through friction and pressure feedback.
