Abstract

一种操作模式自动识别方法及终端，所述方法包括：采集作用于触控屏幕上的触控事件，提取所有触控事件产生的输入事件；调用预先建立的各操作模式的标准模型，根据所述输入事件，进行标准模型匹配，并将匹配的标准模型对应的操作模式作为识别出的操作模式。

Description

操作模式自动识别方法及终端 技术领域
本文涉及但不限于通信领域，尤其涉及一种操作模式自动识别方法及终端。
背景技术
智能终端的屏幕尺寸越来越大，这个情况给单手操作带来很大困扰，移动终端的界面或者按键并不随着用户的使用习惯发生变化，比如，用户使用过程中最常用的返回按键，如果设置在最右侧，使用左手操作时，操作返回键非常不方便。
关于智能判断左手右手操作的方法，目前已经存在一些方案，例如：
方案一：通过判断终端的屏幕旋转状态，动态配置按键的方案；
方案二：通过设置在终端两侧的光感模块自动判断用户对终端的手持状态的方案；
方案三：通过终端内置偏转角度传感器，检测用户操作时终端的偏移角度来识别左手或右手操作的方案；
方案四：通过获取手指的指纹纹路进而识别左手或右手操作的方案。
上述已存在的技术方案，一定程度上解决了智能判断左手或右手操作的问题，但同时也可以看到，上述几种方案均存在一些弊端，有进一步需要改进的地方。具体表现为：
方案一、方案三都是借助传感器的作用获取终端的旋转角度，进而进行左右手的判断，这种方案可能会出现误判，因为用户使用左手或右手操作，终端都会出现多类旋转角度，所以，单独以旋转角度作为依据，不够充分；
方案二需要配备额外的光感模块，增加了设备成本和结构复杂度，通用性不强；
方案四以图形和指纹纹路识别为基础，这种方法需要额外的图形判别模块来识别用户按压屏幕的图形，然后，需要增加指纹纹路识别功能，这些方 式首先需要额外的硬件或模块支持，增加终端成本。另外，在图形或指纹纹路识别过程中，需要一定的算法和运算，这些会消耗更多的电量，图像识别算法很占用CPU，给终端性能带来影响。最后，图形或指纹识别本身并不是百分之百准确，存在一定的误判可能性。

本发明的实施方式
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做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。
为了解决相关技术中操作模式识别方式存在的多种不足，本发明实施例提供一种操作模式自动识别方法，该方法基于终端触摸屏输入事件遵循多点触控协议(Multi-touch Protocol)，在用户操作屏幕过程中，触摸屏驱动程序会按照多点触控协议中的制定的规则，上报输入事件给上层程序，本发明实施例通过解析驱动上报的这些输入事件，可以实现智能判断用户为左手、右手还是双手的操作方式。
如图1所示，本发明实施例提供一种操作模式自动识别方法，所述方法包括如下步骤：
步骤S101，采集作用于触控屏幕上的触控事件，提取触控事件产生的输入事件；
所述输入事件包括：触控事件接触中心坐标点位置和中心坐标点为触控事件接触中心坐标点的接触椭圆区域的方向(例如，接触椭圆区域的长轴所指示的方向)；
可选地，所述输入事件还包括中心坐标点为触控事件接触中心坐标点的接触椭圆区域的大小；(例如，接触椭圆区域的面积的大小、或周长、或长轴、或短轴)
如图2所示，为多点触控协议规定的部分输入事件(即本发明实施例所用到的输入事件)的解释，包括：
ABS_MT_POSITION_X，表示触控事件的接触中心X轴坐标；
ABS_MT_POSITION_Y，表示触控事件的接触中心Y轴坐标；
ABS_MT_TOUCH_MAJOR，表示触控事件接触椭圆区域的长轴；
ABS_MT_TOUCH_MINOR，表示触控事件接触椭圆区域的短轴；
ABS_MT_ORIENTATION，表示触控事件接触椭圆区域的方向；可选的，当触控事件接触椭圆区域的长轴和屏幕坐标系Y方向对齐时返回0值，触控事件接触椭圆区域的长轴向左转时返回负值，向右转时返回正值。
具体如何提取触控事件产生的输入事件可以采用本领域技术人员的公知技术实现，并不用于限定本发明的保护范围，这里不再赘述。比如安卓(Android)系统下，可以通过监控/dev/input下的输入设备节点文件获取输入事件。
步骤S102，调用预先建立的所有操作模式的标准模型，根据所述输入事件，进行标准模型匹配，并将匹配的标准模型对应的操作模式作为识别出的操作模式。
本实施例中，操作模式的标准模型可以包括终端内的固有配置(即终端出厂时的默认配置)，可选的是通过采集用户的触控操作而建立的符合本用户使用习惯的标准模型。此时，标准模型建立过程包括：
(1)为用户提供交互界面，并提示用户在一种操作模式下进行操作；
(2)采集一定数量的触控事件作为标准样本事件，并记录标准样本事件产生的输入事件；
(3)根据记录的标准样本事件产生的输入事件，对当前操作模式进行标准模型建模；
(4)提示用户在下一种操作模式下进行操作，重复上述采集及建模过程，直到所有操作模式均建模完成。
可选的，操作模式的标准模型包括：操作模式对应的操作区域、操作模 式对应的操作区域内多个接触椭圆区域的方向；可选地，还包括操作模式对应的操作区域内多个接触椭圆区域的大小。
而根据输入事件，进行标准模型匹配，主要是考量触控事件接触中心坐标点位置所属的操作区域、以及中心坐标点为接触中心坐标点的接触椭圆区域的方向与接触中心坐标点所属的操作区域对应的标准模型中中心坐标点为与接触中心坐标点相同或相近坐标点的接触椭圆区域的方向的相似度；
具体如何计算中心坐标点为接触中心坐标点的接触椭圆区域的方向与接触中心坐标点所属的操作区域对应的标准模型中中心坐标点为与接触中心坐标点相同或相近坐标点的接触椭圆区域的方向的相似度可以采用本领域技术人员的熟知技术实现，并不用于限定本发明的保护范围，这里不再赘述。
可选地，为了提高判断的精确度，还需要考量中心坐标点为接触中心坐标点的接触椭圆区域的大小与接触中心坐标点所属操作区域对应的标准模型中中心坐标点为与接触中心坐标点相同或相近坐标点的接触椭圆区域的大小的相似度。
具体如何计算中心坐标点为接触中心坐标点的接触椭圆区域的大小与接触中心坐标点所属操作区域对应的标准模型中中心坐标点为与接触中心坐标点相同或相近坐标点的接触椭圆区域的大小的相似度可以采用本领域技术人员的公知技术实现，并不用于限定本发明的保护范围，这里不再赘述。
可选地，为了提高识别准确度，本实施例中，根据输入事件进行标准模型匹配过程中，采用多个触控事件的输入事件进行的标准模型匹配。此时，在模型匹配时，主要考量的是每一个触控事件接触中心坐标点位置落在每一个操作模式对应的操作区域内的比例，以及每一个中心坐标点为接触中心坐标点的接触椭圆区域的方向(或者方向和大小)与每一个接触中心坐标点所属操作区域对应的标准模型中中心坐标点与接触中心坐标点相同或相近坐标点的接触椭圆区域的方向(或者方向和大小)的相似度。例如，当比例和相似度都达到设定的对应阈值则可判定为符合某操作模式。当然，本领域技术人员也可以在本发明实施例思想下，自定义模型匹配策略。
另外，在操作模式识别后，可以将识别的结果通知给用户，供用户判断识别的结果是否正确，在正确的情况下，判断采集到的触控事件的输入事件 信息是否均在对应操作模式的标准模型库内，若在，则不作处理，若不在，将不在标准模型库内的触控事件的输入事件存入标准模型库中，实现标准模型的自学习。
可选地，本发明实施例所述方法，还包括：在识别出操作模式后，按照识别的操作模式，调整终端操作界面的布局方式。即调整终端操作界面的布局方式为当前操作模式对应的布局方式。其中，终端操作界面的布局方式包括：虚拟键盘的布局方式。
具体如何调整终端操作界面的布局方式可以采用本领域技术人员的熟知技术实现，并不用于限定本发明的保护范围，这里不再赘述。
可见，本实施例所述方法能够在终端相关输入系统基础上，不增加额外的硬件和软件模块，智能识别用户的操作方式，并自动调整终端的操作界面设置，方便了用户操作，较大程度的提升产品的用户体验。
为了更清楚的阐述本发明，下面结合附图3至5给出本发明的一个较佳实施例，该实施例通过披露更多的技术细节对本发明所述方法进行更详尽的阐述，需要指出的是，披露的技术细节用于解释本发明并不用于唯一限定本发明。
如图3所示，本发明实施例中终端屏幕区域划分为A、B、C、D四个区域。当用户使用左手单手操作终端时，触控事件的坐标主要集中在A区域和C区域；当用户使用右手单手操作终端时，触控事件的坐标主要集中在B区域和C区域；D区域靠近终端屏幕上方，使用单手操作时，触控事件的坐标较少位于此区域内。
如图4所示，本发明实施例中左手单手操作时触控事件的坐标主要集中在A区域和C区域，且A区域和C区域内每个位置的接触椭圆区域的大小、方向具有规律性。
如图5所示，本发明实施例中右手单手操作时触控事件的坐标主要集中在B区域和C区域，且B区域和C区域内每个位置的接触椭圆区域的大小、方向具有规律性。
通过图4和图5可以看出，当使用左手单手操作和右手单手操作时，触控事件的坐标位置均会落在C区域，但使用左单手操作和右手单手操作时，C区域内接触椭圆的方向是不一样的，二者的方向一般具有约90度的差异，也就是ABS_MT_ORIENTATION的值存在正负的差异。
由图3至图5可知，当用户使用左手单手操作时，操作触摸屏的位置主要集中在终端屏幕左下角的扇形区域内，且区域内每个位置每次操作的触摸屏接触椭圆区域的大小、方向基本保持一致，即固定位置上触控事件的ABS_MT_TOUCH_MAJOR和ABS_MT_TOUCH_MINOR的大小基本保持不变，ABS_MT_ORIENTATION正负值基本保持不变；当用户使用右手单手操作时，操作触摸屏的位置主要集中在终端屏幕右下角的扇形区域内，且区域内每个位置每次操作的触摸屏接触椭圆区域的方向基本保持一致，即固定位置上触控事件的ABS_MT_TOUCH_MAJOR和ABS_MT_TOUCH_MINOR的大小基本保持不变，ABS_MT_ORIENTATION正负值基本保持不变。
所以，本发明实施例可以建立多种操作模式的标准模型，作为操作模式自动识别的判断依据。
本实施例中，操作模式的标准模型建模方式包括：
步骤1，采集左手单手操作时的输入事件。为了提高识别准确度，在具体实施时，可以由终端提供交互界面给用户，提示用户使用左手单手操作，采集一定数量的左手单手操作屏幕时的事件作为标准样本事件。
采集的具体内容包括用户使用左手单手操作终端，用户在左手单手可以触及的范围内进行点击、滑动等触控操作产生的输入事件。
步骤2，生成左手单手操作模式输入事件的标准模型。当输入事件采集工作完成后，根据采集到的事件特征点进行标准建模，得到左手单手操作输入事件标准模型。
具体的建模内容包括：由ABS_MT_POSITION_X、ABS_MT_POSITION_Y确定的输入中心坐标点范围，以此来建立图3中所示A和C所在的区域；由ABS_MT_TOUCH_MAJOR、ABS_MT_TOUCH_MINOR、ABS_MT_ORIENTATION确定的每个接触中心 坐标点位置上接触椭圆区域的大小和方向。
步骤3，采集右手单手操作时的输入事件，其过程类似步骤1。
步骤4，生成右手单手操作模式输入事件标准模型，其过程类似步骤2。
按照与左右手的标准模型建模方式，也可以得到双手操作模式输入事件标准模型，但考虑到用户所能使用的操作模式不外乎三种：左手单手操作、右手单手操作和双手操作，所以，也可以不建立双手操作模式输入事件的标准模型，而是通过排除单手操作的方式来判断是否为双手操作模式。
可选地，在步骤2和步骤4所建立的标准模型基础上，综合得到图3所示的A区域、B区域、C区域、D区域的范围，以及分析得到分别在使用左手单手操作和右手单手操作时，C区域内椭圆方向的差异。
在标准模型建立后，即可利用标准模型对操作模式进行自动识别，识别过程如下：
S1，识别初始化，清空已缓存的输入事件，开始进行操作模式识别。
S2，采集一定数量的连续的用户操作触摸屏时的触控事件，并记录下一系列的ABS_MT_POSITION_X、ABS_MT_POSITION_Y、ABS_MT_TOUCH_MAJOR、ABS_MT_TOUCH_MINOR、ABS_MT_ORIENTATION事件序列；
S3，统计采集到的事件序列中的ABS_MT_POSITION_X、ABS_MT_POSITION_Y所确定的坐标位置分布，并统计分析每个坐标位置上由ABS_MT_TOUCH_MAJOR、ABS_MT_TOUCH_MINOR、ABS_MT_ORIENTATION所确定的触摸屏接触椭圆区域的大小和方向。
S4，根据预先建立的所有操作模式的标准模型，确定统计结果所符合的操作模式包括：
当采集到的触控事件中，坐标分布在屏幕左下角A和C区域的比例达到设定的阈值，且每个中心坐标点为接触中心坐标点的接触椭圆区域的大小、方向和左手单手操作标准模型下中心坐标点为该接触中心坐标点位置或者与该接触中心坐标点位置相近的坐标点(即标准模型中没有该坐标点位置的数据，所以采用与该坐标点位置相近的坐标点代替)的椭圆的大小、方向相似 度达到设定的阈值时，则认为用户当前使用的是左手单手操作。
当采集到的触控事件中，坐标分布在屏幕右下角B和C区域的比例达到设定的阈值，且每个中心坐标点为接触中心坐标点的接触椭圆区域的大小、方向和右手单手操作标准模型下中心坐标点为该接触中心坐标点位置或者与该接触中心坐标点位置相近的坐标点的椭圆大小、方向相似度达到设定的阈值时，则认为用户当前使用的是右手单手操作。
当采集到的触控事件中，坐标分布在的区域未达到阈值，每个中心坐标点为接触中心坐标点的接触椭圆区域的大小、方向的相似度也未达到设定阈值时，则认为用户当前使用的是双手操作。
上述每一个阈值可以根据需求灵活设定，每一个阈值的取值可以相同或不同。
在一个可选实施例中，为了提高识别效率，可以仅考虑坐标位置分布比例和C区域内接触椭圆区域的方向，而将A区域内每个中心坐标点为接触中心坐标点的接触椭圆区域的大小和方向的判断作为补充，可以根据设置选择是否将A区域内每个中心坐标点为接触中心坐标点的接触椭圆区域的大小和方向作为判断依据。
下面以识别左手单手操作为例对该优选实施例进行阐述：
首先，分析触控事件的接触中心坐标点位置所在区域，当触控事件中心坐标点位置集中在图3中A区域和C区域的数量比例达到一定阈值时，则判定用户使用左手单手操作的必要条件之一已经具备。
其次，分析触控事件在C区域内接触椭圆区域的方向，并将结果和左手单手操作标准模型中C区域内的触摸椭圆区域的方向进行比较，当相似度达到预设的阈值时，则判断用户使用左手单手操作的另外一个必要条件之一已经具备。
作为补充，分析触控事件在A区域内每个接触椭圆区域的大小和方向，并将结果和左手单手操作标准模型中A区域内的接触椭圆区域的大小和方向进行比较，当相似度达到预设的阈值时，则判断用户使用左手单手操作的一个补充条件已经具备。
最后，根据上述分析判断结果，综合断定用户是否使用的是左手单手操作。对右手单手操作进行识别判断的过程和上述步骤类似，在此不再赘述。
S5，当成功识别操作模式后，根据识别结果，自动调整终端的相关设置，包括虚拟键盘的布局、操作界面布局等，并弹出消息提示用户终端已经设置为左手操作模式或右手操作模式。
S6，当单手操作自动识别开关始终打开时，流程进入S1开始下一轮识别；当自动识别开关关闭时，流程结束。
本发明实施例还提供一种终端，如图6所示，包括：
触摸屏驱动器610，设置为采集作用于触控屏幕上的触控事件；
