具体实施方式
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。
如图1所示，图1为本发明触摸屏智能设备文字处理方法的第一实施例的流程图。本实施例提到的触摸屏智能设备文字处理方法，包括：
步骤S101，当检测到触摸屏触点的数量为两个时，保存两个触点的初始坐标；
本实施例的智能设备的触摸屏支持多点触控技术，当用户同时将两个手指放在触摸屏上时，智能设备检测到两个触点，并保存两个触点的初始坐标，此时，智能设备将两个初始坐标之间的文字确定为用户需要进行文字处理的文字。
步骤S102，当检测到两个触点消失时，判断两个触点的最终坐标的间距是否小于预设阈值；
当用户在收拢两指间的距离时，智能设备检测到两触点的间距减小，当手指离开触摸屏时，两触点的间距小于预设的阈值时，智能设备判定用户需要进行文字处理操作，弹出文字处理提示菜单，供用户选择。例如，两个触点的初始坐标之间的初始距离为D（0），可将预设阈值设置为初始距离D（0）的百分比，例如预设阈值设置为80% D（0），当D（x）<80% D（0）时，判定用户希望复制或剪切文字；或将预设阈值设置为一个范围，例如预设阈值设置为60% ~80%D（0），当60% D（0）<D（x）<80% D（0）时，判定用户希望复制或剪切文字；或将预设阈值设置为一固定距离，例如1字符宽度，当D（x）<1字符宽度时，判定用户希望对文字进行文字处理操作。
步骤S103，当两个触点的最终坐标的间距小于预设阈值时，触发文字处理提示菜单。
文字处理提示菜单可包括复制/剪切选择框、搜索选择框、文字保存选择框、字体缩放选择框等，根据用户选择的内容进行相应的文字处理操作。
本实施例在用智能设备进行文字处理操作时，利用多点触控技术分析用户手势，根据触摸屏的触点状况，获得用户文字编辑操作意图，使文字处理操作更加方便、响应更加迅速。
如图2所示，图2为本发明触摸屏智能设备文字处理方法的第二实施例的流程图。本实施例以复制/剪切操作为例，此时，文字处理提示菜单显示为复制/剪切选择框。
步骤S201，当检测到触摸屏触点的数量为两个时，保存两个触点的初始坐标；
步骤S202，当检测到两个触点消失时，判断两个触点的最终坐标的间距是否小于预设阈值；
步骤S203，当两个触点的最终坐标的间距小于预设阈值时，显示复制/剪切选择框；
步骤S204，接收用户选择的复制或剪切指令，复制或剪切两个触点的初始坐标之间的文字。
复制/剪切选择框可包括“复制”选项、“剪切”选项和“取消”选项。当用户选择“复制”选项时，智能设备保存两个触点的初始坐标之间的文字到系统的粘贴板上；当用户选择“剪切”选项时，智能设备保存两个触点的初始坐标之间的文字到系统的粘贴板上，并删除原坐标上的文字；当用户选择“取消”选项时，智能设备不作任何操作。
本实施例在用智能设备进行复制/剪切操作时，利用多点触控技术分析用户手势，根据触摸屏的触点状况，获得用户文字编辑操作意图，使复制/剪切操作更加方便、响应更加迅速。
如图3所示，图3为本发明触摸屏智能设备文字处理方法的第三实施例的流程图。本实施例以图2所示实施例为基础，包括：
步骤S301，当检测到触摸屏触点的数量为两个时，保存两个触点的初始坐标；
步骤S302，当检测到两个触点消失时，判断两个触点的最终坐标的间距是否小于预设阈值；
步骤S303，当两个触点的最终坐标的间距小于预设阈值时，显示复制/剪切选择框。
步骤S304，接收用户选择的复制或剪切指令，复制或剪切两个触点的初始坐标之间的文字。
步骤S305，当在文字编辑区检测到单个触点时，保存单个触点坐标，显示粘贴选择框；
本实施例的智能设备在检测到一手指落到文字编辑框内，产生一个触点，弹出粘贴选择框。
步骤S306，接收用户选择的粘贴指令，将两个触点的初始坐标之间的文字粘贴至单个触点坐标。
粘贴选择框包括“粘贴”选项、“取消”选项和“结束”选项。当用户选择“粘贴”选项时，将之前复制或剪切的文字粘贴到单个触点坐标；当用户选择“取消”选项时，不进行如何操作；当用户选择“结束”选项时，清除保存的文字和触点坐标。本实施例通过手指触点操作，使智能设备上的粘贴操作更加简单。
如图4所示，图4为本发明触摸屏智能设备文字处理方法的第四实施例的流程图。本实施例以图1所示实施例为基础，包括：
步骤S401，当检测到触摸屏触点的数量为两个时，保存两个触点的初始坐标；
步骤S402，当检测到两个触点消失时，判断两个触点的最终坐标的间距是否小于预设阈值；
步骤S403，当两个触点的最终坐标的间距小于预设阈值时，触发文字处理提示菜单。
步骤S404，当两个触点的间距增大时，判定用户取消操作，清除保存的两个触点的初始坐标。
本实施例中，当用户在收拢两指间距时，认为选择的文字范围不是自己想要的，可让两指向外划开，智能设备在检测到两触点距离增大，即判定用户取消操作，清除两触点的初始坐标。本实施例通过触点的聚拢或分离，可轻松实现文字选择或取消选择，操作更加方便，系统响应速度更快。
如图5所示，图5为本发明触摸屏智能设备文字处理方法的第五实施例的流程图。本实施例以图1所示实施例为基础，包括：
步骤S501，当检测到触摸屏触点的数量为两个时，保存两个触点的初始坐标；
步骤S502，当两个触点的间距缩小时，两个触点的初始坐标之间的文字向两个触点的中间位置聚拢；
本实施例在用户收拢手指时，触点间的文字向中间收拢，在显示界面上给人一种文字被手指捏起的视觉效果，提高了用户视觉体验。
步骤S503，当检测到两个触点消失时，判断两个触点的最终坐标的间距是否小于预设阈值；
步骤S504，当两个触点的最终坐标的间距小于预设阈值时，触发文字处理提示菜单；
步骤S505，当两个触点的间距增大时，两个触点的初始坐标之间的文字向两个触点的两端分开。
当触点向外分离时，触点间的文字随触点向外分开，在显示界面上给人一种文字被手指放下的视觉效果，进一步提高了用户视觉体验。
如图6所示，图6为本发明触摸屏智能设备文字处理方法中判断触点间距缩放情况的步骤流程图，包括以下步骤：
步骤S601，启动定时器，根据定时器中预设的检测频率，检测两个触点的间距；
本实施例的移动终端对触摸屏的触点坐标进行定时检测，并计算两个触点的间距，例如，将预设的检测频率设置为每20毫秒检测一次。
步骤S602，在当前检测的距离小于前一次检测的距离时，判定两个触点的间距缩小；
假设当前检测的距离为D（x），前一次检测的距离为D（x-1），当D（x）< D（x-1）时，说明两触点间的距离在缩小。
步骤S603，在当前检测的距离大于前一次检测的距离时，判定两个触点的间距增大。
当D（x）>D（x-1）时，说明两触点间的距离在缩小。
本实施例利用多点触控技术分析用户手势，根据实时监测触点间距，获得用户文字编辑操作意图，使复制/剪切操作更加方便、响应更加迅速。
