摘　　要：针对目前常用手写设备存在的信息获取不全面问题,提出了一种支持笔交互的手写输入设备;该设备不仅可以获得笔交互过程静态轨迹的信息,而且还可以全面获取手写动态信息,特别是手写多维力信息;整个系统由传感器模块,数据测量模块、主控系统模块和显示模块组成;分析了各个模块的工作和设计原理,并给出具体的实现结构框图;讨论了系统的优化设计,以提高系统的性能;实验部分通过设计一个简单的笔迹显示程序验证了笔交互设备的性能,结果表明,设计的笔交互设备能够实现对笔交互过程手写全力信息的获取,并提供了一种自然的交互效果。Aiming at the insufficiency of present pen-interaction devices on handwriting information acquisition, a novel handwriting device is designed and implemented. The device is capable of capturing both the static trajectory of the writing pen and the dynamic handwriting information, particularly the multi-axis handwriting force information. The system consists of sensor module, data measurement module, main control system module and display module. The operation and design principles of the four modules are analyzed, and the concrete implementation block diagram is given. The system optimization design is discussed, which can improve the system performance. A simple hand-writing display program was designed and it can be used to verify the performances of the handwriting device. The results show that the designed handwriting device has the capability of acquiring all the handwriting force information during pen interaction process and provides a nature interaction effect and experience.
