摘　　要：摘要探讨了将倾角信息引入基于力信息的签名识别是否能有效消除传统数字书写笔在书写过程中须保持固定姿态的这种限制，是否会对系统的识别性能产生影响。采用书写力传递的方法，将倾角信息与力传感器的信息相结合，实现了多传感器信息融合，并将含有倾角信息的书写力与无倾角信息的书写力进行了识别性能对比试验。结果表明，在固定握笔姿态下，倾角信息对识别率的影响不大，而在自由握笔姿态下，倾角传感器与力俜感器相结合可以有效棍高系统识别，障骺．The problem that whether the introduction of the dip angle information of a digital pen for signature verification into the foree-based signature verification can effectively eliminate the restriction that ordinary digital pens require the writer to hold them in a fixed posture during handwriting and affect the performance of the recognition system was investigated. The method of force transmission was used to combine the inclination sensor information with the force sensor information to realize multi-sensor information fusion. The experiments were eondueted to compare the recognition capability of force signals with or without incorporating dip angle information. The results showed that dip angle information had little impact on the recognition rate when the digital pens were in a fixed posture. On the other hand, it played an important role when a pen was at a free posture. The combined information of a inclination sensor and a force sensor can improve the recognition performance of the system remarkably.
