随着触控技术不断发展更新，为适应消费者需求，触控交互产品与设备也逐步向大尺寸化发展，由原来的55寸、65寸为主流交互产品慢慢发展到现在的以75寸、85寸为主流，触控交互产品的显示面板的屏幕比例也出现更多选择。随着人们对交互体验要求的提高，消费者开始越来越多地关注到人机交互的性能，例如触控交互的响应速度、书写细腻程度、触控笔迹跟随速度等，但是随着触控交互产品尺寸不断扩大，触控方法和算法也变得比较复杂，目前大尺寸触控交互设备的交互体验效果还很难到达到人们的预期。触控点坐标精度下降而带来的交互响应速度变慢、书写细腻程度欠佳、跟随速度等各方面触控性能问题也慢慢突显。
针对上述问题，本申请实施例提供一种分区触控方法、装置与电子设备，将大尺寸触控交互设备的整体触控区域分解为多个小尺寸触控区域，对于每个小尺寸触控区 域而言，其内部触控点定位精度更高，先在小尺寸触控区域内获取高端精度触控点坐标数据，再将其汇总转换为大尺寸触控区域下的触控点坐标，触控点定位精度不会下降，从而能够有力保证大尺寸触控交互产品的触控性能与体验更优。
在一方面，本申请实施例提供了一种分区触控方法。
如图1所示，本申请实施例提供的一种分区触控方法，应用于触控显示设备，触控显示设备包括一触控屏，触控屏的整体触控区域被划分为至少两个子区域，分区触控方法包括以下步骤：
S1：接收用户对触控屏的触控操作；
S2：判断触控操作相应触控点所属的子区域；
S3：获取触控点所属的子区域对应的触控扫描数据；
S4：根据触控扫描数据计算触控点在触控点所属的子区域内的坐标数据，并将所述坐标数据确定为次级坐标数据；
S5：根据触控点所属的子区域与整体触控区域的位置关系与几何比例，将次级坐标数据转换为整体坐标数据。
其中，整体触控区域往往为矩形，此外，整体触控区域还可以为除矩形外的其他形状，对此不做限定。
利用本申请实施例中的分区触控方法可以将整体触控区域分解为至少两个子区域，例如可以将矩形的整体触控区域分解为左右两小矩形子区域或上下两小矩形子区域，或划分为上中下或者左中右三子区域，或者左上、中、右下三子区域等，或者呈井格状划分为九个小的子区域等。可以理解的是对于整体触控区域的划分有多种不同划分方式，具体采用划分方式可以根据具体的触控交互产品中触控显示屏幕的整体触控区域而定。但是不论采用何种子区域划分方式，获得的子区域其尺寸必定比整体尺寸更小，对于每个小的子区域而言，其内部触控点定位算法相互独立，在小尺寸子区域内进行触控点定位，其精确度一定更高。
在划分子区域后，在在接收到用户对触控屏的触控操作时，判断触控点所属的子区域，从而针对相应子区域确定触控点的次级坐标数据，此时所确定的次级坐标数据的精确度较高。之后再根据小尺寸子区域与整体触控区域的位置关系与几何比例，将高精度的次级坐标数据转换为整体坐标数据，在这一过程中坐标数据的精确度保持不变，最后确定的整体坐标数据也保有高精确度，从而保证大尺寸触控交互产品的触控性能与体验更优。
在本申请的一个或多个实施例所提供的一种分区触控方法中，获取实时子区域对应的触控扫描数据之前，方法还包括：
控制触控扫描电路对子区域进行扫描。
在分区触控方法中，采用控制触控电路对子区域进行扫描的方式实现对整体触控区域的分区触控扫描，从而获取子区域对应的触控扫描数据。确定触控点所属的子区 域后，控制触控扫描电路只对触控点所属的子区域进行扫描，相比整体触控区域，针对小尺寸子区域的触控扫描减少了触控扫描面积，在保证精确度提高的同时还能够提高触控扫描效率。
如图2所示，在本申请实施例提供的一种分区触控方法中，触控显示设备在整体触控区域边界处设置检测设备4，步骤S2，包括：
接收检测设备对触控体的方位检测信息，根据方位检测信息确定触控体相对检测设备的距离与方向；
根据触控体相对检测设备的距离与方向，确定触控体相应的触控点所属的子区域。
设置在整体触控区域边界的检测设备用于检测触控体，能够获取到相应的方位检测信息，据此对与触控体相对应触控点所处的子区域进行判断。
其中，用户可以通过触控体来执行相应的触控操作，则触控体与触摸显示屏幕接触的位置即为触控点。可选地，触控体表示触摸显示屏可以对其触控作出响应的物体，例如触控笔等具有触摸头的触控设备，或者用户的手指等器官，对此不作限定。
参考图2所示，图2为整体触控区域分区示意图，图中以矩形整体触控区域为例，其中竖线阴影部分表示第一个子区域(记为触控区域1)，横线阴影部分表示第二个子区域(记为触控区域2)。
如图2所示，在本申请实施例提供的一种分区触控的方法中，两相邻子区域存在重叠区域(记为触控区域3)。
当检测到触控点位于重叠区域(触控区域3)时，根据监测设备4对触控体的跟踪检测，确定触控体运动趋势；
根据触控体运动趋势判定相应触控点所属的子区域。
将整体触控区域分解为至少两个子区域后，相邻两子区域相接边界附近是比较特殊的位置，当触控点位于此区域甚至恰好落在两子区域相接边界线上时，其触控点坐标定位工作就变得非常困难，也非常容易出现误差。因此，在分区触控方法中，在进行区域划分时，设置两相邻子区域间存在重叠部分即如图2所示的重叠区域，需要注意的是重叠区域的宽度不宜过宽，一般将重叠区域宽度设置为30mm左右，可以根据实际情况作出适应性调整。当触控点位于重叠区域时，检测设备4对触控体进行跟踪检测，以确定触控体的运动趋势，当触控体的运动趋势为从触控区域1向触控区域2运动，则判定触控点位于触控区域2；相反的，当触控体的运动趋势为从触控区域2向触控区域1运动，则判定触控点位于触控区域1。
采用上述方法，能够保证跨子区域触控点坐标数据连续性，保证触控点在所属的子区域内的次级坐标数据足够准确。
本领域技术人员应当理解的是，检测设备4可以是任意一种能够获取与触控体相对距离与角度(方向)的装置，例如检测设备可以是雷达模块、摄像头或距离传感器 等能够实现动态追踪功能的装置，在一个或多个实施例中检测设备可以选取动态追踪传感器，能够更迅速的确定触控体的运动趋势，从而更迅速完成对触控点所属子区域的判定操作，进而缩减触控响应时间，优化触控体验性能。
本申请的一个或多个实施例所提供的一种分区触控方法，还包括：
接收检测设备4对触控体的状态检测信息；
在转换得到整体坐标数据后，根据状态检测信息对整体坐标数据的有效性进行判定；
若状态检测信息内容为空，则整体坐标数据无效，将整体坐标数据丢弃。
考虑到大尺寸触控交互产品与设备的应用场景，触控交互产品周围往往会存在较多的干扰项，可能造成出现异常整体坐标数据，为避免异常整体坐标数据造成的影响，检测设备4在对触控体进行检测时还生成状态检测信息，用以表征是否存在触控体，若不存在触控体则状态检测信息的内容为空。当触控体不存在而又获取到了整体坐标数据，则说明整体坐标数据为异常数据，这样的整体坐标数据是无效的。
在本申请的一个或多个实施例所提供的一种分区触控方法中，根据子区域与整体触控区域的位置关系与几何比例，将次级坐标数据转换为整体坐标数据，包括：
根据位置关系与几何比例确定坐标数据转换公式；
根据次级坐标数据，利用坐标数据转换公式，计算确定整体坐标数据。
参考图3所示，与参考图2的区域划分结果相对应(左边为触控区域1，右边为触控区域2，中间重叠部分为触控区域3)，为整体触控区域的尺寸示意图。其中X是整体触控区域的物理长度最大坐标数据S(单位：分辨率),X1为触控区域1的坐标尺寸实际的物理长度，最大坐标数据S1(单位：分辨率)；X2是触控区域2的坐标尺寸实际的物理长度,最大坐标数据S2(单位：分辨率)；X3表示的是X与X2的差，即X3＝X-X2；理论上S1＝S2＝S，可以根据实际情况进行设定。
参考图4所示，为触控点落在触控区域1中位置示意图,其中A表示触控点横轴上的实际物理长度。此时在子区域触控区域1中确定触控点坐标为(x,y)，将转换后的整体坐标数据记为(x’,y’)。根据触控区域1与整体触控区域的位置关系以及几何比例，可以确定坐标数据转换公式为下述公式(1)：
Figure PCTCN2020106733-appb-000001
参考图5所示，图5为触控点落在触控区域2中位置示意图，其中B表示触控点横轴上的实际物理长度。此时在子区域触控区域2中确定触控点坐标为(x,y),将转换后的整体坐标数据记为(x’,y’).根据触控区域2与整体触控区域的位置关系以及几何比例，可以确定坐标数据转换公式为下述公式(2)：
Figure PCTCN2020106733-appb-000002
相同的，当采用其他的子区域划分方式时，根据触控点所在子区域与整体触控区域的位置关系和几何比例，都可以确定坐标数据转换公式，从而将高端精度的次级坐标数据转换为整体坐标数据。
在另一方面，本申请实施例还提供了一种分区触控装置。
