具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及部分实施例，对本发明部分实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例一
本发明实施例一提出一种通过压力检测有效触摸点的方法，用于移动终端，该移动终端包括触控系统和压力检测系统，上述触控系统包括电容传感器、光学传感器等具备检测触摸信号的器件，上述压力检测系统包括压力传感器等。如图1所示，本发明实施例一的方法包括如下步骤：
S1、触控系统接收触摸信号。
S2、触控系统根据触摸信号检测所有原始触摸点，并将检测到的所有原始触摸点发送至压力检测系统。
触控系统对触摸信号进行分析，检测所有可能的按压点，触控系统可通过触摸屏上的电容变化值，检测并计算出所有触摸点，本发明实施例一称之为原始触摸点，原始触摸点可能包括了由于干扰或噪声等原因带来的异常点，本发明实施例一称之为无效触摸点，触控系统将所有原始触摸点记录为向量Vp，并发送至压力检测系统。
S3、压力检测系统解析每个原始触摸点的压力信息，并根据每个原始触摸点的压力信息判断每个原始触摸点是否为无效触摸点，并将所有的无效触摸点发送至所述触控系统。其中，判断每个所述原始触摸点是否为无效触摸点是通过判断每个原始触摸点的压力信息是否达到预设的标准，当一原始触摸点的压力信息未达到预设的标准时，压力检测系统将该原始触摸点判断为无效触摸点。
步骤S3中，压力检测系统根据触摸点的压力信息的不同设置对应的标 准，当触摸点的压力信息为力度时，设置一压力阈值作为最小的触摸点力度，遍历所有原始触摸点，计算原始触摸点的力度，小于该压力阈值的一触摸点则判定为无效触摸点。具体地，压力检测系统通过压力传感器上的电容变化值yp，由预设的统计分布函数yp＝f(xp)计算出各个原始触摸点对应的压力值xp，即触摸点力度。其中，统计分布函数f(·)为事先通过大量数据统计得到的拟合函数，每一电容变化值yp唯一对应一压力值xp，将该压力值与上述压力阈值比较，即可判断该原始触摸点是否为人手或触摸笔的正常物理按压产生，还是由其它非正常物理按压产生。
当触摸点的压力信息为压力等级时，设置一压力等级阈值作为最小的压力等级，遍历所有原始触摸点，计算原始触摸点的压力等级，小于该压力等级阈值的一触摸点则判定为无效触摸点。
上述触摸点的压力信息还可以是除力度和压力等级以外的其它可以用以衡量无效触摸点的压力信息，且力度、压力等级等压力信息可单独使用或组合使用。
压力检测系统标识无效触摸点，作为标识信息Fp传递回触控系统。
S4、触控系统接收所有的无效触摸点并根据接收的所有的无效触摸点，对所述所有原始触摸点重新计算，得到有效触摸点。
触控系统根据压力检测系统传递的无效触摸点的标识信息Fp，可以对无效触摸点所在区域的数据进行干扰和噪声的滤除，排除掉Vp中非正常按压产生的无效触摸点，触控系统对滤除干扰和噪声的区域的数据重新处理，对存在异常触摸点的一定范围内的数据做消除处理，并用非按压点附近的数据代替，再计算并输出有效触摸点准确的按压坐标，得到并输出有效触摸点的坐标。
实施例一以水雾产生的干扰为例进行说明。
在雨水或者水雾较大时，用户使用带有触摸屏的设备时容易在屏幕上产生一层水雾或水珠，降低正常的手指按压的灵敏度，甚至导致些功能键乱启动， 严重影响正常使用，给用户给来不便。
归其原因，触控系统虽然检测出触摸点，但由于干扰很难消除，因此会输出包含无效触摸点的按压坐标，表现为在不同位置上有触摸点，当触摸点落在些功能键上就会触发些程序的响应。
利用实施例一的方法，触控系统将检测出的所有原始触摸点，传递给压力检测系统，压力检测系统根据数据检测出水雾带来的无效触摸点产生的按压力度较小，力度小于压力阈值的触摸点标识为无效触摸点，并将标识信息传递回触控系统，触控系统根据这些标识信息，排除掉水雾带来的无效触摸点，而输出正常的按压坐标。从而达到消除水雾干扰的目的。
实施例一利用外界环境对压力检测的影响较小，提供一种利用压力检测与触控交互的方法，利用压力检测技术排除触摸屏上由于外界干扰带来的无效触摸点，提高触控坐标点计算的准确度，从而达到提高用户体验的效果。

接收单元131，用于接收无效触摸点的标识信息；
滤除单元132，用于根据无效触摸点的标识信息，对无效触摸点所在区域进行干扰和噪声的滤除；
输出单元133，用于在所有原始触摸点所在的区域进行滤除后的区域，重新进行坐标计算，输出有效触摸点的坐标。
滤除单元132根据压力检测系统传递的无效触摸点的标识信息Fp，可以对无效触摸点所在区域的数据进行干扰和噪声的滤除，排除掉Vp中非正常按压产生的无效触摸点，输出单元133根据滤除干扰和噪声的区域的数据，计算并输出准确的按压坐标，得到真实触摸点。
本发明实施例二的装置，其工作原理具体如下：
触控系统10的检测模块12对接收模块11接收到的触摸信号进行分析，检测所有可能的按压点，本发明实施例二称之为原始触摸点，原始触摸点可能包括了由于干扰或噪声等原因带来的异常点，本发明实施例二称之为无效触摸点，检测模块12将所有原始触摸点记录为向量Vp，并发送至压力检测系统20。
压力检测系统20中的设置单元215预先根据触摸点的压力信息的不同设置对应的标准，当触摸点的压力信息为力度时，设置一压力阈值作为最小的触摸点力度，第一计算单元211遍历所有原始触摸点，计算原始触摸点的力度，小于该压力阈值的一触摸点则由第一判定单元212判定为无效触摸点。具体地，压力检测系统通过压力传感器上的电容变化值yp，由预设的统计分布函数yp＝f(xp)计算出各个原始触摸点对应的压力值xp，即触摸点力度。其中，统计分布函数f(·)为事先通过大量数据统计得到的拟合函数，每一电容变化值yp唯一对应一压力值xp，将该压力值与上述压力阈值比较，即可判断该原始触摸点是否为人手或触摸笔的正常物理按压产生，还是由其它非正常物理按压产生。
当触摸点压力信息为压力等级时，设置一压力等级阈值作为最小的压力等级，第二计算单元213遍历所有原始触摸点，计算原始触摸点的压力等级，小于该压力等级阈值的一触摸点则由第二判定单元214判定为无效触摸点。
上述触摸点的压力信息还可以是除力度和压力等级以外的其它可以用以衡量无效触摸点的压力信息，且力度、压力等级等压力信息可单独使用或组合使用。
压力检测系统20的解析模块22标识无效触摸点，作为标识信息Fp传递回触控系统10。
触控系统10的接收单元131接收压力检测系统20传递的标识信息Fp，滤 除单元132对滤除干扰和噪声的区域的数据重新处理，对存在异常触摸点的一定范围内的数据做消除处理，并用非按压点附近的数据代替，输出单元133计算并输出有效触摸点准确的按压坐标，得到并输出有效触摸点的坐标。
实施例二的装置利用外界环境对压力检测的影响较小，通过压力检测与触控交互的技术，利用压力检测技术排除触摸屏上由于外界干扰带来的无效触摸点，提高触控坐标点计算的准确度，从而达到提高用户体验的效果。
以上所述仅为本发明的部分较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
