摘　　要：手写运动中对手写力信息的全面获取,一直是人机交互领域中解决人-机交互信息带宽不匹配的重点。本文设计了一种手写输入装置,该装置由五维力传感器、数据采集模块和显示模块构成,可以实时直接测量用户手写产生的五维力信息,并显示用户手写的结果。利用快速小波变换技术提取了手写多维力信息的特征,结合实际的汉字手写过程对提取到的主要特征分量进行定性分析。该装置和信号处理方法的应用为多维空间手写运动分析提供基础,特别为手-脑协调障碍疾病分析提供生物力学研究途径。Handwriting Force Information Acquisition has been the focus of research in the field of human-computer interaction.Handwriting input device which can measure the writing multi-dimensional forces and display the writing results in real time directly,is proposed in this paper.It is composed of a five-dimensional force sensor（FFS）,a data acquisition module and a display module.The features of multi-dimensional force information are extracted by fast wavelet transform and the feature vectors are analyzed by a handwritten Chinese characters process.The application of the instrument and the signal processing method is benefit for the analysis of multi-dimensional handwriting movements.It provides a biomechanical analysis approach for the hand-brain coordination disorder particularly.
