具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
目前，对触摸屏的触控测试方法为：在触摸屏上进行划线测试，即沿着触摸屏表面的平行方向进行触控测试。然而，本申请的发明人注意到，在实际触控交互过程中，敲击触控响应的准确性是衡量触控测试的一项重要指标。
如图1和图2所示，本公开实施例提供一种触控测试装置，其包括伸缩机构1、触控部件2、触摸屏3、获取单元4和运算单元5。伸缩机构1被配置为长度可调节；触控部件2连接于伸缩机构1的伸缩部1B，伸缩部1B用于带动触控部件2敲击触摸屏3；获取单元4用于获取触控部件2针对触摸屏3的同一目标坐标点敲击触摸屏3的实际检测坐标点；运算单元5用于计算触控部件2敲击触摸屏3的目标坐标点与实际检测坐标点之间的触控坐标误差。
例如，如图4所示，伸缩机构1包括本体1A和连接于本体1A的伸缩部1B，伸缩部1B用于相对于本体1A伸缩运动，以使伸缩机构1的长度增大或减小，并且这样的伸缩机构1的结构简单且有助于对触摸屏的触控测试的准确性提供更加客观公正的结果。在这种情况下，例如，伸缩机构1可以为电动缸或液压缸，或者其他能够进行直线往复运动的传动机构等，此处不作 限定。以液压缸为例，液压缸的缸筒为本体，液压缸的活塞杆为伸缩部。在其它实施例中，伸缩结构1可以为其它类型的长度可调节的结构(例如电动弹簧)。伸缩机构1带动触控部件2敲击触摸屏3的次数、速度(即垂直方向上的速度)、时间(即敲击同一目标坐标点的时间间隔)等均可进行控制，以实现触控性能中的水平方向和竖直方向的快速敲击性能进行测试。
触控部件2可以为能够在触摸屏3上进行触控的物体(也可称为测试棒)，测试棒与触摸屏3相触碰的端部可以设计为凸弧形，以利于测试棒与触摸屏3完全触碰上。
当触控部件2敲击触摸屏3时，触控部件2敲击触摸屏3的实际检测坐标点通过获取单元4进行获取，实际检测坐标点与触控部件2敲击触摸屏3的目标坐标点会有位置偏差，其中，目标坐标点为预先设定好的触控位置，使触控部件2位于触摸屏3的目标坐标点的上方位置，然后通过伸缩机构1带动触控部件2进行敲击触摸屏3，敲击触摸屏3时获取单元4获取到的坐标点为实际检测坐标点。例如，获取单元4可以为触控传感器等，只要获取单元4实现获取触控的实际检测坐标点即可，此处不作限定。
计算获取到的实际检测坐标点与目标坐标点之间的触控坐标误差，通过运算单元5进行计算。例如，触控坐标误差的计算可以采用处理器来完成该计算，则运算单元5为处理器的运算逻辑部件。实际检测坐标点与目标坐标点之间的触控坐标误差即为两坐标点之间的距离值。
本公开实施例提供的一种触控测试装置，通过伸缩机构带动触控部件敲击触摸屏，通过获取单元获取触控部件敲击触摸屏的实际检测坐标点，通过运算单元计算触控部件敲击触摸屏的目标坐标点与实际检测坐标点之间的触控坐标误差，以实现触摸屏的敲击触控测试，进一步完善了触摸屏的触控交互测试，有助于对触摸屏的触控测试的准确性提供更加客观公正的结果。
例如，伸缩机构1用于带动触控部件2多次敲击触摸屏3；获取单元4用于获取触控部件2多次敲击触摸屏3的多个实际检测坐标点，运算单元5用于计算触控部件2敲击触摸屏3的目标坐标点分别与多个实际检测坐标点之间的距离的最大值，该最大值为触控部件2敲击触摸屏3的触控坐标误差。当使一触控部件2位于触摸屏3的目标坐标点的上方位置，并进行多次敲击触摸屏3时，获取单元4获取到多次实际检测坐标点，将该多次实际检测坐 标点的数据传输至运算单元5，运算单元5利用下述计算式计算触控坐标误差，计算式为：
Figure PCTCN2019083469-appb-000002
其中，x a为该触控部件敲击所述触摸屏的目标坐标点，x r1...x rn分别为获取单元获取到的多个实际检测坐标点。其中，计算多次触控交互响应的误差值，然后选取最大值，能够使计算结果更加准确可靠。
例如，本公开实施例提供的触控测试装置还包括移动机构6，移动机构6连接于伸缩机构1(例如连接于伸缩的本体1A)，移动机构6用于带动伸缩机构1(例如伸缩结构1的本体1A)至少沿平行于触摸屏3的方向移动。通过移动机构6可使连接于伸缩机构1的触控部件2移动至触摸屏3的目标坐标点的上方位置。
例如，如图4所示，移动机构6可包括连接于伸缩机构1本体1A的移动臂6A以及连接于移动臂6A的驱动机构(例如伺服电机等)6B，通过驱动机构6B控制移动臂6A的移动位置。此处本公开实施例对移动机构6的具体结构不作限定，只要移动机构6至少能沿平行于触摸屏3的方向移动即可。例如，根据测试要求，通过移动机构6带动连接于伸缩机构1的触控部件2沿预设轨迹移动，移动机构6至少可以沿平行于触摸屏3的方向移动。例如，移动机构6沿x和y方向移动；在此基础上，例如，也可以设计为能够沿垂直于触摸屏3的方向移动，即z方向，以调节触控部件2距离触摸屏3的高度。移动机构6可带动触控部件2在触摸屏3上进行划线测试，即沿着触摸屏3表面的平行方向进行触控测试。
例如，触控部件2的数量为多个(这些触控部件2对应不同的目标坐标点)，伸缩机构1的数量与触控部件2的数量相同，以进行多点触控性能测试。例如，如图1所示，多个伸缩机构1都与移动机构6连接并且分别与多个触控部件2一一对应地连接；通过同一移动机构6连接多个触控部件2，可控制该多个触控部件2在同一水平面内移动，以确保水平方向的测试。例如，如图4所示，每个伸缩机构1的伸缩部1B连接于一个触控部件2；多个伸缩机构1的本体1A均连接于一个移动机构6。一个移动机构6可同时带动多个伸缩机构1相对于触摸屏3移动，每个伸缩机构1分别连接有一个触控部件2，可分别控制每个触控部件2敲击触摸屏3，实现多点敲击触控操作，每个触控部件2敲击触摸屏3的动作相互之间可不受影响。
例如，如图2所示，触控测试装置包括控制单元7，多个伸缩机构1分别连接于控制单元7，控制单元7用于控制多个伸缩机构1(例如该多个伸缩机构的伸缩部)依照预设次序依次交替伸缩运动，以带动相应的触控部件2依照预设次序依次交替敲击触摸屏3。例如，在设置有N个触控部件2的情况下，第1个触控部件2至第N个触控部件2逐个敲击触摸屏。参见图3，控制多个伸缩机构1带动多个触控部件2依照预设次序依次交替敲击触摸屏3，可以采用处理器来完成，则控制单元7为处理器的控制部件。例如，控制单元7还可控制伸缩机构1的伸缩部的伸缩次数、时间、速度等，以相应的控制触控部件2敲击触摸屏3的次数、时间、速度等，此处不作限定。交替敲击触摸屏3，可使获取单元4每次获取到一个实际检测坐标点，可有效保证获取到实际检测坐标点准确可靠。
例如，本公开实施例提供的触控测试装置还包括载台8，载台8用于放置触摸屏3。例如，载台8上可以设置有固定结构，以固定触摸屏3；载台8适宜制成水平面，以将触摸屏3水平放置在载台8上，并使触摸屏3固定不动，通过控制移动机构6和伸缩机构1来完成触控部件2敲击触摸屏3的触控交互响应测试。
在本公开实施例中，通过实现触摸屏的敲击触控测试，使得进一步完善了触摸屏的触控交互测试，有助于对触摸屏的触控测试的准确性提供更加客观公正的结果。
如图5所示，本公开实施例提供一种触控测试方法，其包括以下步骤101至103。

102、获取触控部件敲击触摸屏的实际检测坐标点。
参见图1和图2，当触控部件2敲击触摸屏3时，可通过获取单元4获 取触控部件2敲击触摸屏3的实际检测坐标点。例如，获取单元4可以为触控传感器等，或者其它任意类型的能够获取触控的实际检测坐标点的部件，此处不作限定。使触控部件2位于触摸屏3的目标坐标点的上方位置后，控制触控部件2敲击触摸屏3，目标坐标点为预先设定好的触控位置，实际检测坐标点与触控部件2敲击触摸屏3的目标坐标点会有位置偏差。
103、计算触控部件敲击触摸屏的目标坐标点与实际检测坐标点之间的触控坐标误差。
例如，实际检测坐标点与目标坐标点之间的触控坐标误差即为两坐标点之间的距离值，参见图1和图2，该步骤可通过运算单元5来完成，例如，运算单元5可为处理器的运算逻辑部件。
本公开实施例提供的一种触控测试方法，通过控制触控部件敲击触摸屏，获取触控部件敲击触摸屏的实际检测坐标点，计算触控部件敲击触摸屏的目标坐标点与实际检测坐标点之间的触控坐标误差，以实现触摸屏的敲击触控测试，进一步完善了触摸屏的触控交互测试，有助于对触摸屏的触控测试的准确性提供更加客观公正的结果。
例如，可以通过多次敲击触摸屏来提高触控测试的准确性。例如，如图6所示，本公开实施例提供的触控测试方法包括如下步骤201至204。
201、通过移动机构控制触控部件移动至相对于触摸屏的目标触控位置。
可采用上述实施例的触控测试装置进行触摸屏的敲击触控测试，例如，参见图1和图2，触控测试装置包括移动机构6、伸缩机构1和触控部件2，移动机构6连接于伸缩机构1，用于带动伸缩机构1至少沿平行于触摸屏3的方向移动，触控部件2连接于伸缩机构1，伸缩机构1用于带动触控部件2敲击触摸屏3。例如，根据测试要求，通过移动机构6带动连接于伸缩机构1的触控部件2沿预设轨迹移动。移动机构6至少可以沿平行于触摸屏的方向移动，例如移动机构至少可以沿x和y方向移动；或者，在此基础上，移动机构6也可以设计为能够沿垂直于触摸屏3的方向移动，即z方向，以调节触控部件2距离触摸屏3的高度；移动机构6可带动触控部件2在触摸屏3上进行划线测试，即沿着触摸屏3表面的平行方向进行触控测试。
例如，触控部件2的数量为多个，一个移动机构6可同时带动多个伸缩机构1相对于触摸屏3移动，每个伸缩机构1分别连接有一个触控部件2， 可分别控制每个触控部件2敲击触摸屏3，实现多点敲击触控操作，每个触控部件2敲击触摸屏3的动作相互之间可不受影响。
202、控制多个触控部件依照预设次序依次交替敲击触摸屏。
参见图1、图2和图3，该步骤可通过控制单元7来完成，例如，控制单元7可为处理器的控制部件。例如，控制单元7可控制伸缩机构1依照预设次序依次交替伸缩运动，以带动相应的触控部件2依照预设次序依次交替敲击触摸屏3。例如，控制单元7还可控制伸缩机构1的伸缩部的伸缩次数、时间、速度等，以相应的控制触控部件2敲击触摸屏3的次数、时间、速度等，此处不作限定。
203、获取任一触控部件多次敲击触摸屏的多个实际检测坐标点。
参见图1和图2，当使一触控部件2位于触摸屏3的目标坐标点的上方位置，并进行多次敲击触摸屏3时，获取到的是多次实际检测坐标点，需要说明的是，该触控部件2相对于触摸屏3的同一触控位置的目标坐标点不变。
204、根据计算式
Figure PCTCN2019083469-appb-000003
计算触控部件敲击触摸屏的触控坐标误差，其中，x a为任一触控部件敲击触摸屏的目标坐标点，x r1...x rn分别为多个实际检测坐标点。
也就是说，将一触控部件每一次敲击的触控交互响应的误差值计算出来，然后取最大值，作为该触控部件敲击触摸屏的触控坐标误差，计算结果更加准确可靠。
