摘要
针对如何利用触摸屏获取手写签名过程中动态信息的问题,讨论基于TMS320C5402的硬件设计方法并给出相应的示例。用该方法所获取的手写签名过程中的压力、签名总时间、速度、加速度等动态信息,基本达到手写签名认证算法的需要。
To deal with the problem of acquisition the dynamic data of handwriting signature with touch-screen. The way of hardware design with TMS329C5402 and an example of the application of this technique are discussed. The information of pressure, total time, velocity、 and acceleration gotten from the signing process with this technique can adapt to the needs of verification algorithm.
