图5是根据本发明优选实施例的一种压力屏的压力类别识别的流程图，如图5所示，该流程图包括的步骤如下：
步骤S501：用户按压触摸屏，触摸屏产生了0.32V的连续压力值；
步骤S502：模数转换装置以1ms的周期对该压力采样及进行转换。输出8位数字压力值0010 0000(周期1ms)即32；
步骤S503：消除抖动装置采用积分方式，即将连续输入的10个压力值进行累加，然后数学平均:其中，n为压力值的数量，f(n)为压力值。通过这种方式去除按压过程中的毛刺现象。本装置同时也可以起连“0”检测作用，可用于判断是否存在输入，当连续输入多个“0”的时候，判断用户不再处理，关闭处理功能，延长设备使用周期；
步骤S504：将压力值空间从低到高按以e(约2.72)为底的指数划分，数字值共256级，划分轻、中、重三个分类，即中压空间是轻压空间的e倍，而重压空间是中压空间的e倍，三个空间分类集合划分为(0,23]，(24,84]，(85,255]，三个分类集合的编号分别为A、B、C。输入的压力数字值是00010000，即32，与空间分类集合的上下限比较，属于中压，编号为B，映射转换完成。图6是根据本发明优选实施例的一种压力值与分类空间映射关系的原理图，如图6所示；
步骤S505：将压力编号B作为计算结果输出，供其他应用调用。
当用户要重压屏幕使用某些应用的时候，由于重压的分类空间足够大，手指在按压过程中有足够多的键程，对应用户感觉重压空间弹性很大；当用户轻压某些应用的时候，由于轻压的分类空间相对较少，按键过程中很容易切换到中压的空间，即用户感觉上轻压灵敏度很高。通过上两种情况可知，相对于线性划分空间，基于指数的非线性空间划分，与人的实际体验更一致，用户体验更好。
