智能写字板是一种新型的人机交互领域的电子设备，通过智能写字板，用户可以在智能写字板的书写区域铺垫传统纸张，然后用普通笔芯在传统纸张上书写，就可以将用户书写的文字同步到手机或者平板中，实现手写内容的实时数字化，使得真实笔迹能够永久清晰保存，还能留存真实手写感。
但是，当前智能写字板都是默认用户的触控点到智能写字板之间的垂直距离不变，在确定用户的触控坐标时，都是采用固定的补偿值对坐标进行补偿，而不考虑用户在智能写字板上铺设的纸张的厚度，从而在用户更换不同类型的纸张或者铺垫不同类型的纸张进行书写时，由于触控点到智能写字板之间的距离变化，导致智能写字板输出的触控点的坐标误差较大。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
需要说明的是，本申请实施例中所涉及到的终端可以是智能写字板，也可以是具有与智能写字板相同功能终端，例如智能手机、平板电脑、个人数字助理(Personal Digital Assistant，PDA)、移动互联网设备(Mobile Internet Device，MID)、智能穿戴设备(如智能手表、智能 手环)等，还可以是具有触摸屏，且在使用过程中触控点到触摸屏的垂直距离会发生改变的终端，本发明实施例不作限定。
下面结合图1至图3，对终端确定触控点坐标的方法进行介绍。如图1所示，图1是一种触摸屏感应通道分布示意图，在图1中，触摸屏中共分布有12个感应通道，分别为感应通道1至感应通道12，以触摸屏的左上角的顶点为坐标原点，以相交于所述坐标原点的触摸屏的两条边作为x轴和y轴建立直角坐标系，其中，在x轴方向上的任意两个相邻感应通道之间的第一距离相同，在y轴方向上的任意两个相邻感应通道之间的第二距离相同，所述第一距离与所述第二距离可以相同，也可以不同，上述两个相邻感应通道之间的距离均是指两个感应通道的中心点之间的距离。如图2所示，图2是图1所示触摸屏的正视图，即图2中三个感应通道中心点的连线平行于x轴，由于触控点P与感应通道之间存在有介质材料，例如智能写字板上铺设的纸张，因此触控点与触摸屏之间存在一定的触控感应距离h。在确定触控点坐标时，若终端确定感应通道8的感应值A 1为最大感应值，则终端可以获取与感应通道8在x轴方向上相邻的感应通道7的感应值A 2以及感应通道9的感应值A 3，根据感应值A 2和感应值A 3确定触控点的坐标，具体的，触控点P的横坐标x P与感应值A 2以及感应值A 3满足如下公式：
Figure PCTCN2018104698-appb-000001
Figure PCTCN2018104698-appb-000002
其中，A 3大于或者等于A 2，M 1为在x轴方向上相隔一个感应通道的两个感应通道的中心点之间的像素点个数，即感应通道7的中心点O 7和感应通道9的中心点O 9之间的像素点数量，Δx 0为x轴坐标补偿值，用于补偿x轴方向上因为触控感应距离导致的误差。
如图3所示，图3是图1所示触摸屏的左视图，即图3中三个感应通道的中心点连线平行于y轴，根据上述原理，可以得到触控点P的纵坐标y P满足如下公式：
Figure PCTCN2018104698-appb-000003
其中，A 5大于或者等于A 4，A 4为与感应通道8在y轴方向上相邻的感应通道5的感应值，A 5为与感应通道8在y轴方向上相邻的感应通道11的感应值，M 2为在y轴方向上相隔一个感应通道的两个感应通道的中心点之间的像素点个数，即感应通道5的中心点O 5和感应通道11的中心点O 11之间的像素点数量，Δy 0为y轴坐标补偿值，用于补偿y轴方向上因为触控感应距离导致的误差。
但是，上述确定触控点坐标的方法中，终端(例如智能写字板)输出的触控点坐标是在固定厚度下，按照固定的坐标补偿值确定的，即对于一智能写字板，在确定触控点坐标的过程中，获取到的触控点到感应屏的触控感应距离不变，坐标补偿值(x轴坐标补偿值与y轴坐标补偿值)为固定值。在用户在智能写字板上铺垫不同厚度的纸张的情况下，例如两次书写过程中铺垫的纸张类型不同或者铺垫的纸张数量不同，会导致触控点到感应屏的触控感应距离变化，例如当触控感应距离增大时，感应通道的感应值会随着触控感应距离的增大而减 小，而靠近触控点的感应通道的感应值下降速率比远离触控点的感应通道的感应值的下降速率快，这样会导致得到的触控点坐标误差增大，而由于终端不能在用户每次使用时检测触控点到感应屏的触控感应距离，从而不能根据不同的触控感应距离选择不同的坐标补偿值，导致在不同触控感应距离下最终得到的触控点坐标的误差增大，触控精度降低。
针对上述问题，本申请提供一种确定触控感应距离的方法，请参见图4，图4是本申请实施例提供的一种确定触控感应距离的方法流程图，如图4所示，该方法包括：
步骤101，在第一触控点位于触摸屏第一感应通道的中心点上方的情况下，获取所述第一感应通道的第一感应值以及第二感应通道的第二感应值。
其中，第一感应通道为触摸屏多个感应通道中的任意一个感应通道，第二感应通道与第一感应通道相邻，其中，所述第二感应通道可以是在x轴方向上与所述第一感应通道相邻的感应通道，也可以是在y轴方向上与所述第一感应通道相邻的感应通道，本申请实施例不做具体限制。具体的，如图5所示，图5中以第二感应通道是在x轴方向上与所述第一感应通道相邻为例进行说明，示出了第一感应通道与第二感应通道之间的位置关系图以及第一触控点P 1与第一感应通道以及所述第二感应通道之间的位置关系。其中，点O 1为所述第一感应通道的中心点，点O 2为所述第二感应通道的中心点。
本申请实施例中，在检测到所述第一感应通道在x轴方向上两个相邻的感应通道的感应值相同的情况下，或者在检测到所述感应通道在y轴方向上两个相邻的感应通道的感应值相同的情况下，确定所述第一触控点位于所述第一感应通道中心点上方。在确定所述第一触控点位于所述第一感应通道中心点上方的情况下，获取所述第一感应通道的感应值以及所述第二感应通道的第二感应值。
步骤102，根据所述第一感应值、所述第二感应值以及所述第一感应通道与所述第二感应通道之间的距离，确定所述触控感应距离。
其中，所述第一感应通道与所述第二感应通道之间的距离为所述第一感应通道的中心点与所述第二感应通道的中心点之间的距离，即在x轴方向上相邻的两个感应通道的中心点之间的距离，该距离在设计触摸屏时已经确定，在本申请实施例中以常数a表示。所述触控感应距离为第一触控点与所述第一感应通道的中心点之间的垂直距离，即所述第一触控点与终端触摸屏之间的垂直距离。
本申请实施例中，在获取所述第一感应值，所述第二感应值以及所述第一感应通道的中心点与所述第二感应通道的中心点之间的距离a之后，根据感应通道的感应值以及触控点到感应通道中心点之间的距离关系，确定所述第一触控点与所述第一感应通道的中心点之间的垂直距离。具体的，感应通道的感应值与触控点到感应通道中心点的距离成反比关系，如图5所示，在图5中，所述第一触控点P 1与第一感应通道的中心点O 1之间的触控感应距离、所述第一感应值以及所述第二感应值满足如下公式：
Figure PCTCN2018104698-appb-000004
其中，h为所述第一触控点P 1与第一感应通道的中心点O 1之间的触控感应距离，A为所述第一感应值，B为所述第二感应值。
根据上述公式3确定所述触控感应距离h为：
Figure PCTCN2018104698-appb-000005
通过实施本申请实施例，能够在用户每次在终端的触摸屏上进行触控或者书写操作时，重新确定用户的触控点与所述终端的触摸屏之间的触控感应距离，进而能够根据不同的触控感应距离选择不同的坐标补偿值，或者根据不同的触控感应距离计算触控点坐标，以减少由于触控感应距离的变化而导致终端最终确定的触控点坐标与实际触控点坐标之间的误差，提高触控精度。
在一种可能的实施例中，根据上述步骤确定的所述触控感应距离h可以作为用户本次使用终端的过程中，所有触控点与触摸屏之间的触控感应距离，即在本次操作过程的开始，用户开始在终端的触摸屏上进行触控操作时，即根据上述方法确定一个触控感应距离h 1，将该触控感应距离h 1作为本次整个操作过程中的触控感应距离。在下一次用户开始在终端触摸屏上进行操作时，再根据上述方法确定一个触控感应距离h 2，将该触控感应距离h 2作为本次整个操作过程中的触控感应距离。例如，若所述终端为智能写字板，当用户在所述智能写字板上铺垫好纸张开始进行书写时，根据上述方法确定一个触控感应距离h 1，若终端在一段时间段内，每隔预设时长都能够检测到触控操作，则将该时间段内用户的操作作为一次操作过程，将所述触控感应距离h 1作为本次操作的触控感应距离；若终端在本次检测到用户的触控操作后，在预设时间段内没有再次检测到触控操作，则终端将下一次检测到的触控操作作为另一次操作过程，再次根据上述方法确定一个触控感应距离h 2，比如用户在智能写字板上书写两个汉字，若用户在书写两个汉字之间的间隔时间小于或者等于预设时长，则将书写这两个汉字的过程认为是一次操作过程，只需在开始书写第一个汉字时确定一次触控感应距离，若用户在开始书写第二个汉字与书写完第一个汉字之间的时间间隔大于所述预设时长，则将书写这两个汉字的过程认为是两次操作过程，终端需要在用户开始书写第二个汉字时再次确定一次触控感应距离。又例如，若所述智能写字板上具有固定纸张的装置，比如采用磁力吸附装置，利用相互吸引的磁极固定纸张，则终端在检测到磁力吸附装置两磁极间的相互作用力变化超过预设阈值的情况下，即认为变化前后是两次不同的操作过程，触控感应距离可能发生改变，比如用户打开磁力吸附装置增加或者撤出纸张，则终端在磁力吸附装置的两极间相互作用力由变化变为稳定之后，若检测到触控操作，则需要再次确定一次触控感应距离。
在一种可能的实施例中，终端可以在检测到触控操作后，采用上述方法确定多个初始触控感应距离，计算所述多个初始触控感应距离的平均值作为最终的触控感应距离，并将最终的触控感应距离作为本次操作的触控感应距离，由于通过单个触控点确定触控感应距离时，所述单个触控点是用户随机触控的，通过多个初始触控感应距离计算平均值的方法确定最终触控感应距离，以减少通过单个触控点确定触控感应距离的随机误差，提高最终确定的触控感应距离的准确性。
在一种可能的实施例中，终端可以在触控点位于每个感应通道的中心点上方时，都根据上述方法确定一次触控感应距离，终端将触控点位于一个感应通道上方时确定的触控感应距离，作为以该感应通道中心点为中心的预设区域内的触控感应距离。举例来讲，在图2中，在终端检测到感应通道7的感应值以及感应通道9的感应值相同的情况下，确定触控点位于感应通道8的中心点上方，此时确定感应通道8对应的触控感应距离h 8，并将触控感应距离h 8作为以感应通道8的中心点O 8为中心的矩形区域的触控感应距离，当终端确定触控点位于感应通道9的中心点上方，此时终端再次确定感应通道9对应的触控感应距离h 9，并将触控感应距离h 9作为以感应通道9的中心点O 9为中心的矩形区域的触控感应距离，其中，所述矩形区域如图6所示，所述矩形区域平行于x轴的边的边长等于x轴方向上相邻的两个感应通道的中心点之间的距离a，所述矩形区域平行于y轴的边的边长等于y轴方向上相邻的两个感应通道中心点之间的距离，所述矩形区域的对角线相交于感应通道的中心点。
通过实施上述实施例中的方法，可以在用户进行触控操作时，每次经过感应通道中心点上方时均确定一次触控感应距离，提高了终端确定触控感应距离的频率，使每次确定的触控感应距离所对应的触控区域的面积更小，由于每个触控感应距离可以对应一组坐标补偿值，因此每组坐标补偿值对应的触控面积也更小，进而能够提高终端最终输出的触控点的坐标的精度。
本申请实施例中，请参见图7，图7是本申请实施例提供的一种根据触控感应距离确定触控点坐标的方法的流程示意图，如图7所示，该方法包括：
步骤201，在第一触控点位于触摸屏第一感应通道的中心点上方的情况下，获取所述第一感应通道的第一感应值以及第二感应通道的第二感应值。
步骤202，根据所述第一感应值、所述第二感应值以及所述第一感应通道与所述第二感应通道之间的距离，确定所述触控感应距离。
其中，步骤201的执行方法请参照上述实施例中的步骤101，步骤202的执行方法请参照上述实施例中的步骤102，在此不再赘述。
步骤203，根据所述触控感应距离确定与所述触控感应距离对应的坐标补偿值。
本申请实施例中，坐标补偿值包括x轴坐标补偿值以及y轴坐标补偿值，终端可以存储有触控感应距离与坐标补偿值关联的关联表，例如，触控感应距离h 1对应的一组坐标补偿值为(Δx 1,Δy 1)，触控感应距离h 2对应的一组坐标补偿值为(Δx 2,Δy 2)等，在终端确定一个触控感应距离之后，则从所述关联表中查找与所述触控感应距离对应的组坐标补偿值，以用于确定触控点的坐标。
步骤204，根据所述坐标补偿值确定第二触控点的坐标。
本申请实施例中，所述第二触控点为用户在触摸屏上操作时的任意一个触控点，在触控点位于所述第二触控点的情况下，第三感应通道的感应值大于其他感应通道的感应值。
