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的一部分实施例，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。

WiFi属于短距离无线传输技术，电子设备100通过WiFi模块170可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图1示出了WiFi模块170，但是可以理解的是，其并不属于电子设备100的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
蓝牙是一种短距离无线通讯技术。利用蓝牙技术，能够有效地简化掌上电脑、笔记本电脑和手机等移动通信终端设备之间的通信，也能够成功地简化以上这些设备与因特网(Internet)之间的通信，电子设备100通过蓝牙模块180使电子设备100与因特网之间的数据传输变得更加迅速高效，为无线通信拓宽道路。蓝牙技术是能够实现语音和数据无线传输的开放性方案。然图1示出了WiFi模块170，但是可以理解的是，其并不属于电子设备100 的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。

以下以电子设备100为例说明选择文本的方法。
图2为本发明实施例提供的便携式电子设备100的外部结构示意图。在本实施例中，电子设备100可以包括触敏显示单元130、加速度传感器151、音量控制按键132、开关按键133、麦克风162、扬声器161、外部接口197、耳机插孔163。所述触敏显示单元130可以显示用户界面200中的一个或多个图形300，接收用户的触摸输入，通过使用触敏显示单元130作为操作电子设备100的主输入或控制装置，可以减少电子设备100上的物理输入或控制装置的数量。在本实施例中，触敏显示单元可以被称为“菜单按钮”。在一些其他实施例中，“菜单按钮”可以是物理按钮或其他物理输入或控制装置。所述加速度传感器151用于获取用户在触敏显示单元上的触摸动作在Z轴的重力加速度。通过压下并保持所述开关按键在被压下状态达预定时间间隔，可以实现打开或关闭电子设备100的电源。通过压下所述开关按键并在预定时间间隔之前释放，可以实现锁定电子设备100。在其他实施例中，还可以通过麦克风162接收用于激活一些功能的语音输入。
图3为本发明实施例提供的显示文本选择区的示意图。文本选择区301可以在触敏显示单元130上表示为由第一端点302a和第二端点302b限定范围的，位于第一端点和第二端点之间的文本。本领域技术人员可以理解的，选择的文本区301可以包含图3中示出的文本的任何部分，并且在图3中选 择的文本仅仅是一个示例。此外，第一端点302a可以和第一标志杆303a关联，第二端点302b可以和第二标志杆303b关联。第一标志杆303a和第二标志杆303b可以分别用于指示第一端点302a和第二端点302b的位置。由于标志杆比端点容易被操作选取，当用户希望移动第一端点302a或第二端点302b中的一个或全部至新的位置时，可以通过移动与端点关联的标志杆至新的位置以实现移动端点至新的位置。在一些实施例中，标志杆303a和303b可以是其他形状、大小和颜色。本实施例中只是一种示例方式。
图4为本发明实施例提供的选择文本的方法流程图。
方法400可在具有触敏显示单元和多个应用程序(包括文本应用程序)的一种便携式电子设备(例如，图1或图2中的电子设备100)上被执行。在一些实施例中，方法400中的一些操作可以被组合，和/或一些操作的次序可以改变。
如下所述，方法400提供了一种更高效的方式来快速地选择文本。该方法帮助用户通过较少的操作步骤实现选择文本。简化了选择文本的操作步骤，改进了用户体验。
便携式电子设备当检测到作用于触敏表面的关节触摸手势(401)。
例如：步骤401具体可包括步骤4011～4013。
便携式电子设备当检测到作用于触敏表面的触摸动作(4011)；判断所述触摸动作是否是关节触摸动作(4012)；检测由所述关节触摸动作组成的关节触摸手势(4013)。
当检测到作用于所述触敏表面的关节触摸手势后，判断是否存在与所述关节触摸手势的轨迹关联的应用功能(402)。
当判断存在与所述关节触摸手势的轨迹关联的应用功能时，执行所述应用功能(403)。
当判断不存在与所述关节触摸手势的轨迹关联的应用功能时，识别所述显示器显示的用户界面是否是文本应用界面(404)。
示例性的，所述文本应用界面可以显示网页浏览，电子邮件，记事本，即时消息，博客应用等。
如果所述显示器显示的用户界面是文本应用界面，判断所述关节触摸手势的轨迹是否与预设轨迹匹配(405)。
如果所述关节触摸手势的轨迹与预设轨迹匹配，则响应所述关节触摸手势，在所述文本应用界面上显示文本选择区(406)。
当触敏显示单元接收到作用于触敏表面的触摸动作后，将触摸信息传递给处理器。所述触摸信息可以包括触点坐标、触敏显示单元的网格电容值、触摸动作中的一种或多种信号。所述触摸动作可以包括按下、移动以及抬起等动作。
在一些实施例中，可以基于所述网格电容信息以及所述触摸动作产生的Z轴方向加速度信号判断所述触摸动作是否是关节触摸动作(4012)。所述触敏表面网格电容信息包括网格电容值以及非零电容值的网格个数。
当所述网格电容值满足第一预设电容值范围，非零电容值的网格个数小于预设值，且所述Z轴方向加速度信号在第一预设加速度范围时，可以判断所述触摸动作是关节触摸动作。当所述网格电容值满足第二预设电容值范围，非零电容值的网格个数大于或等于预设值，且所述Z轴方向加速度信号在第二预设加速度范围时，可以判断所述触摸动作是手指触摸动作。
例如，当触敏显示单元的网格电容值指示最大电容值满足第一预设电容值范围(比如小于或等于0.42pF)，分布有非零电容值的网格个数小于7，在预设时间内，Z轴方向加速度信号在第一预设加速度范围(比如，在5ms内,加速度信号大于3g)时，可以判断该触摸动作为关节触摸动作。当触敏显示单元的网格电容值指示最大电容值满足第二预设电容值范围(比如大于0.42pF、小于或等于0.46pF)，分布有非零电容值的网格个数大于或等于7，且在预设时间内，Z轴方向加速度信号在第二预设加速度范围(比如，在5ms内，加速度信号小于2g，g为重力加速度)时，可以判断该触摸动作为手指触摸动作。可以理解的是，本发明实施例中的关节触摸动作并非一定由手指关节触发，也可以是其他物体以很快的速度敲击触敏显示单元130，只要满足上述关节触摸动作的判断条件均可称为本发明实施例的关节触摸动作。
触摸手势可以由触摸动作组成。例如，点击手势由按下和抬起两个触摸 动作组成；滑动手势由按下、移动和抬起三个触摸动作组成。当判断所述触摸动作是关节触摸动作后，可以检测由所述关节触摸动作组成的关节触摸手势(4013)。例如：关节点击手势由按下和抬起两个关节触摸动作组成；关节滑动手势由按下、移动和抬起三个关节触摸动作组成。
在一些实施例中，通过查找存储在存储器120中的关节触摸手势的轨迹与应用功能的关联关系，判断是否存在与所述关节触摸手势的轨迹关联的应用功能(402)。所述关节触摸手势可以通过不同的关节触摸动作组成。例如，关节点击手势由按下和抬起两个关节触摸动作组成，关节滑动手势由按下、移动和抬起三个关节触摸动作组成。在按下至抬起之间的移动轨迹为所述关节触摸手势的轨迹。用户可以预先设置多种关节触摸手势的轨迹与应用功能的关联关系，并将所述关节触摸手势的轨迹与应用功能的关联关系保存在存储器120中。
例如，用户可以预先设置关节触摸手势的轨迹“C”与照相应用功能的关联关系，且将所述关节触摸手势的轨迹“C”与照相应用功能的关联关系保存在存储器120中。当检测到作用于触敏表面的轨迹为“C”的关节触摸手势，通过查找所述存储在存储器120中的关节触摸手势的轨迹与应用功能的关联关系，可以判断得知所述关节触摸手势的轨迹“C”与照相应用功能关联。
在一些实施例中，当检测到在触敏显示单元的区A有按下的关节触摸动作，按下后在触敏显示单元上移动至区B，在区B有抬起的关节触摸动作。上述关节在区A按下，移动至区B后抬起的关节触摸事件，为关节触摸手势。例如：通过触点坐标信息可以判断所述触摸动作的位置(例如，区A或区B)。所述关节触摸手势可以由关节触摸动作组成。例如，关节点击手势由按下和抬起两个关节触摸动作组成；关节滑动手势由按下、移动和抬起三个关节触摸动作组成。所述区A为关节触摸手势与触敏显示单元的开始接触区；所述区B为关节触摸手势与触敏显示单元的结束接触区。由区A移动至区B的移动轨迹即为触摸手势的轨迹。电子设备将检测到的关节触摸手势的轨迹与预设轨迹做比较，判断所述关节触摸手势的轨迹是否与预设轨迹匹配(405)。所述预设轨迹信息可以是电子设备出厂预置的，也可以是用户预设的。所述 预设轨迹信息可以保存在存储器中(例如，图1中的存储器120)。
示例性的，以预设轨迹为直线为例，所述直线可以为横线、竖线或者斜线，(例如：“—”、“|”、“/”或“\”)。需要说明的是，所述预设轨迹可以为其他形式的轨迹，可以根据具体设计需求做适应性调整。本发明实施例中以预设轨迹为直线示例，并不构成对本发明方案的限制。
图5为本发明实施例关节触摸手势的轨迹为横线(例如“—”)的示例性用户界面。例如：一开始检测到的关节触摸位置在区A(区A为开始接触区)和随后检测到关节触摸位置移至区B(区B为结束接触区)，关节触摸手势的轨迹为由区A移动至区B的轨迹，如图虚线所示的横线轨迹，箭头方向为关节触摸手势由区A至区B的移动方向。电子设备将所检测到的横线轨迹与预设的直线轨迹做比较，判断所述横线轨迹与预设轨迹匹配。
在一些实施例中，如果判断所述关节触摸手势的轨迹与预设轨迹匹配，则响应所述关节触摸手势，在所述文本应用界面上显示文本选择区(406)。所述文本选择区位于第一端点和第二端点之间，所述第一端点位于所述文本应用界面中第一位置处，所述第二端点位于所述文本应用界面中第二位置处。例如：当判断所述关节触摸手势的轨迹与预设轨迹匹配后，在所述关节触摸手势与触敏显示单元的开始接触区A的位置插入第一端点，在所述关节触摸手势与触敏显示单元的结束接触区B的位置插入第二端点；第一端点的插入位置为第一位置，所述第一位置可以是显示器显示的文本应用界面中最接近所述区A的形心的文本字或词的开始或结尾；第二端点的插入位置为第二位置，所述第二位置可以是显示器显示的文本应用界面中最接近所述区B的形心的文本字或词的开始或结尾；位于所述文本应用界面中第一端点和第二端点之间的文本区域即为所述文本选择区。

在一些实施例中，可以基于所述网格电容信息以及所述触摸动作产生的Z轴方向加速度信号判断所述触摸动作是否是关节触摸动作；所述触敏表面网格电容信息包括网格电容值以及非零电容值的网格个数。
当所述网格电容值满足第一预设电容值范围，非零电容值的网格个数小于预设值，且所述Z轴方向加速度信号在第一预设加速度范围时，可以判断所述触摸动作是关节触摸动作。当所述网格电容值满足第二预设电容值范围，非零电容值的网格个数大于或等于预设值，且所述Z轴方向加速度信号在第二预设加速度范围时，可以判断所述触摸动作是手指触摸动作。
例如，当触敏显示单元的网格电容值指示最大电容值满足第一预设电容值范围(比如小于或等于0.42pF)，分布有非零电容值的网格个数小于7，在预设时间内，Z轴方向加速度信号在第一预设加速度范围(比如，在5ms内,加速度信号大于3g)时，可以判断该触摸动作为关节触摸动作。当触敏显示单元的网格电容值指示最大电容值满足第二预设电容值范围(比如大于0.42pF、小于或等于0.46pF)，分布有非零电容值的网格个数大于或等于7，且在预设时间内，Z轴方向加速度信号在第二预设加速度范围(比如，在5ms内，加速度信号小于2g，g为重力加速度)时，可以判断该触摸动作为手指触摸动作。可以理解的是，本发明实施例中的关节触摸动作并非一定由手指关节触发，也可以是其他物体以很快的速度敲击触敏显示单元130，只要满足上述关节触摸动作的判断条件均可称为本发明实施例的关节触摸动作。

在一些实施例中，当检测到在触敏显示单元的区A有按下的关节触摸动作，按下后在触敏显示单元上移动至区B，在区B有抬起的关节触摸动作。上述关节在区A按下，移动至区B后抬起的关节触摸事件，为关节触摸手势。例如：通过触点坐标信息可以判断所述触摸动作的位置(例如，区A或区B)。所述关节触摸手势可以由关节触摸动作组成。例如，关节点击手势由按下和抬起两个关节触摸动作组成；关节滑动手势由按下、移动和抬起三个关节触摸动作组成。所述区A为关节触摸手势与触敏显示单元的开始接触区；所述区B为关节触摸手势与触敏显示单元的结束接触区。由区A移动至区B的移动轨迹即为触摸手势的轨迹。电子设备将检测到的关节触摸手势的轨迹与预设轨迹做比较，判断所述关节触摸手势的轨迹是否与预设轨迹匹配。所述预设轨迹信息可以是电子设备出厂预置的，也可以是用户预设的。所述预设轨迹信息可以保存在存储器中(例如，图1中的存储器120)。
所述在所述文本应用界面上显示文本选择区，具体为当判断所述关节触摸手势的轨迹与预设轨迹匹配后，在所述文本应用界面上显示文本选择区。所述文本选择区位于第一端点和第二端点之间，所述第一端点位于所述文本应用界面中第一位置处，所述第二端点位于所述文本应用界面中第二位置处。例如：当判断所述关节触摸手势的轨迹与预设轨迹匹配后，在所述关节触摸手势与触敏显示单元的开始接触区A的位置插入第一端点，在所述关节触摸手势与触敏显示单元的结束接触区B的位置插入第二端点。第一端点的插入 位置为第一位置，所述第一位置可以是显示器显示的文本应用界面中最接近所述区A的形心的文本字或词的开始或结尾。第二端点的插入位置为第二位置，所述第二位置可以是显示器显示的文本应用界面中最接近所述区B的形心的文本字或词的开始或结尾。位于所述文本应用界面中第一端点和第二端点之间的文本区域即为所述文本选择区。
