为使本发明的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本发明进一步详细说明。
需要说明的是，本发明实施例中所有使用“第一”和“第二”的表述均是为了区分两个相同名称非相同的实体或者非相同的参量，可见“第一”“第二”仅为了表述的方便，不应理解为对本发明实施例的限定，后续实施例对此不再一一说明。
本发明实施例提出的模式切换方法和装置，可应用于触摸屏、电子白板等触摸输入设备。在用户利用触摸输入设备中安装的编辑软件编辑数据对象时，可以通过触控手势分别实现书写、选择、擦除等多种功能，以及实现书写、选择、擦除等多种功能之间的快速切换，操作便捷、响应迅速、使用方便。上述编辑软件支持触摸设备输入，一般是电子白板或终端的触屏，且支持常用的触控手势的输入操作，如图片缩放等。
图1显示了本发明实施例所述的模式切换方法流程。如前所述，本发明实施例所述的模式切换方法可以应用于触摸屏、电子白板等触摸输入设备。如图1所示，本发明实施例所述的模式切换方法包括以下步骤：
步骤101：检测用户输入的触控信息。
在本发明的实施例中，触控信息是指用户通过手指在触摸输入设备上进行交互时，系统发给软件的触控信息，可以包括：触控点的位置、以及触控时间。上述触控信息还可以包括触控点的宽、高以及压力等信息。
步骤102：对上述触控信息进行处理得到手势操作信息。
在本发明的实施例中，上述手势操作信息可以包括：触控点的类型、触控点的位置、触控点位置间距以及触控点时间间距等信息。
步骤103：确定所述手势操作信息是否符合预先设定的至少一个触控条件之一。
在本发明的实施例中，上述触控条件包括如下判定条件之一或其任意组合：单指书写判定条件、两指选择判定条件以及五指擦除判定条件。
步骤104：在所述手势操作信息符合预先设定的一个触控条件时，根据所述触控信息符合的触控条件进行模式切换。
在本发明的实施例中，上述根据所述触控信息符合的触控条件进行 模式切换可以包括：
在符合单指书写判定条件时，调用书写功能，进入书写操作模式；
在符合两指选择判定条件时，调用选择功能，进入选择操作模式；
在符合五指擦除判定条件时，调用擦除功能，进入擦除操作模式。
在本发明的一些实施例中，上述方法可以进一步包括：
在进入书写操作模式后，退出选择功能，退出擦除功能；
在进入选择操作模式后，退出书写功能，退出擦除功能；或者
在进入擦除操作模式后，退出书写功能，退出选择功能。
在本发明的另一些实施例中，上述方法还可以进一步包括：若所述触控信息不符合预先设定的任意一个触控条件时，则可以返回上述步骤101重新检测用户输入的触控信息。
需要说明的是，虽然在对图1所示实施例中步骤104的描述中，依次对单指书写判定条件、两指选择判定条件、五指擦除判定条件的判断进行了描述，但是，上述描述仅为示例性说明，本发明的实施例并不对上述三个判定条件的判断顺序进行限定。
下面将进一步结合附图详细说明上述图1所示实施例各个步骤的具体实现方法。
在上述步骤102中，依据检测到的用户输入的触控信息(包括触控点的位置以及触控时间等信号)，可以通过处理得到触控点的类型，触控点的位置及触控点位置间距以及触控点时间间距等手势操作信息。
其中，根据触控信息中触控点的位置可以确定触控点的个数，通常，该触控点的个数可以是1～5中的任意数值。进一步，根据触控点的个数，可以将触控点类型分为单指触控点、两指触控点、三指触控点、四指触控点、五指触控点等。
上述触控点位置间距是指一个触控点与其距离该触控点位置最近的另一个触控点之间的间距。上述触控点位置间距可以根据触控信息中触控点的位置确定。
上述触控点时间间距是指落下最早的触控点与落下最晚的触控点之间的时间差，即检测获取的第一个触控点与最后一个触控点之间的时间差值。上述触控点时间间距可以根据触控信息中触控点的时间确定。
在得到手势操作信息之后，则可进一步判断上述操作信息是否符合 预先设定的至少一个触控条件之一。
图2为本发明实施例的单指书写判定条件的判断流程示意图。
在本发明的实施例中，上述单指书写判定条件包括：
条件一：触控点的个数为一个，即为单指触控点；
条件二：单指触控点的位置不在任何两指选择手势区域范围之内；
条件三：单指触控点的位置不在任何五指擦除手势区域范围之内。
上述三个条件同时满足，则判定为符合单指书写判定条件，可进入书写操作模式，在书写操作模式下，可通过单指触控进行书写操作。
如此，如图2所示，上述单指书写判定条件的判断方法包括如下步骤：
步骤201：判断手势信息中的触控点的类型是否为单指触控点，如果是，则执行步骤202；否则，退出本流程；
步骤202：判断手势信息中的触控点的位置是否位于任何两指选择手势区域范围之内或者任何五指擦除手势区域范围之内，如果是，则退出本流程；否则，执行步骤203；
步骤203：判定上述手势信息符合单指书写判定条件。
图3为本发明实施例的两指选择判定条件的判断流程示意图。
在本发明的实施例中，上述两指选择判断条件包括：
条件一：触控点的个数为两个，即为两指触控点；
条件二：两指触控点的位置不在任何单指书写手势区域范围之内；
条件三：两指触控点的位置不在任何五指擦除手势区域范围之内；
条件四：两指触控点的位置间距大于预先设定的选择位置间距，例如，该选择位置间距为40像素；
条件五：两指触控点的时间间距小于或等于预先设定的选择时间间距，例如，该选择时间间距为320毫秒；
条件六：两指触控点落在同一个对象上。
上述六个条件同时满足，则判定为符合两指选择判定条件，可进入选择操作模式，在选择操作模式下，可通过两指触控对同一对象进行选定、拖拽等操作。
如此，如图3所示，上述两指选择判定条件的判断方法包括如下步骤：
步骤301：判断手势信息中的触控点的类型是否为两指触控点，如果是，则执行步骤302；否则，退出本流程；
步骤302：判断手势信息中的触控点的位置是否位于任何单指书写手势区域范围之内或者任何五指擦除手势区域范围之内，如果是，则退出本流程；否则，执行步骤303；
步骤303：判断手势信息中的触控点位置间距是否大于预先设定的选择位置间距，如果是，则执行步骤304；否则，退出本流程；
步骤304：判断手势信息中的触控点时间间距是否小于或等于预先设定的选择时间间距，如果是，则执行步骤305；否则，退出本流程；
步骤305：判断手势信息中的触控点的位置是否均落在同一个对象上，如果是，则执行步骤306；否则，退出本流程；
步骤306：判定上述手势信息符合两指选择判定条件。
图4为本发明实施例的五指擦除判定条件的判断流程示意图。
在本发明的实施例中，上述五指擦除判定条件包括：
条件一：触控点的个数为五个，即为五指触控点；
条件二：五指触控点的位置不在任何单指书写手势区域范围之内；
条件三：五指触控点的位置不在任何两指选择手势区域范围之内；
条件四：五指触控点的位置间距(五个触控点中任意一个触控点与距离其最近的触控点之间的间距)小于或等于擦除位置间距，例如，该擦除位置间距为120像素；
条件五：五指触控点的时间间距(检测到的第一个触控点与第五个触控点之间的时间差值)小于或等于擦除时间间距，例如，该擦除时间间距为400毫秒。
上述五个条件同时满足，则判定为符合五指擦除判定条件，可进入擦除操作模式，在擦除操作模式下，可通过五指触控对操作对象进行擦除操作。
如此，如图4所示，上述五指擦除判定条件的判断方法包括如下步骤：
步骤401：判断手势信息中的触控点的类型是否为五指触控点，如果是，则执行步骤402；否则，退出本流程；
步骤402：判断手势信息中的触控点的位置是否位于任何单指书写手 势区域范围之内或者任何两指选择手势区域范围之内，如果是，则退出本流程；否则，执行步骤403；
步骤403：判断手势信息中的所有触控点位置间距是否均小于或等于预先设定的擦除位置间距，如果是，则执行步骤404；否则，退出本流程；
步骤404：判断手势信息中的触控点时间间距是否小于或等于预先设定的擦除时间间距，如果是，则执行步骤405；否则，退出本流程；
步骤405：判定上述手势信息符合五指擦除判定条件。
另外，在本发明的实施例中，为避免对同一对象的不同位置同时进行擦除而引发操作对象数据错误的问题，对于五指擦除判定条件，可另行增加判定条件六：没有另外一个五指擦除手势正在进行。即，规定同一时间、同一对象仅执行一项擦除操作，以保证操作对象数据的正确性。然而，条件六不作为判断五指擦除判定条件必须满足的条件，也可以对同一对象的不同位置同时进行擦除操作。
需要说明的是，上述图2、3和4显示的是上述各个判定条件分别判断的情形，在本发明的实施例中，也可以结合在一起进行判断，例如，首先确定手势信息中的触控点的类型那种类型，如果是单指触控点，则继续执行步骤202；如果是两指触控点，则继续执行步骤302；如果是五指触控点，则继续执行步骤402。
需要说明的是，在本发明的实施例中，上述的单指书写手势区域范围、两指选择手势区域范围、五指删除手势区域范围，均是可以通过具体操作模式动态确定的。
具体来说，进入书写操作模式后，根据书写操作范围，动态确定出单指书写手势区域范围。例如，根据书写习惯，将包括单指触控点的一定区域范围，确定为单指书写手势区域范围。
进入选择操作模式后，根据选择操作范围，动态确定出两指选择手势区域范围。例如，将由两指拖拽操作的起点到终点所确定的圆形或矩形等具有一定范围的区域，确定为两指选择手势区域范围。
进入五指擦除模式后，根据擦除操作范围，动态确定出五指擦除手势区域范围。例如，将由五指触控点所确定的圆形等具有一定范围的区域，确定为五指擦除手势区域范围。可以理解为，将五指触控点所确定 出的五指擦除手势区域范围作为橡皮擦，用于对操作对象的任意位置进行擦除操作。
图5显示了本发明实施例的同一触摸输入设备上多个手势区域的示例。如图5所示，根据本发明实施例所述的方法，在同一触摸输入设备501上，可同时划分出单指书写手势区域范围502、两指选择手势区域范围503、五指擦除手势区域范围504等多个操作区域，即，在同一个触摸输入设备上，可同时进行书写、选择、擦除等多种操作。而且，这些操作仅在其本次动态确定出的手势区域范围之内执行相应的操作，书写、选择、擦除等功能互斥。例如，在单指书写手势区域范围502之内仅可执行书写操作，不可执行选择、擦除等其他操作；在两指选择手势区域范围503之内仅可执行选择操作，不可执行书写、擦除等其他操作；而在五指擦除手势区域范围504之内仅可执行擦除操作，不可执行书写、选择等其他操作。
根据本发明实施例所述的方法，可分别实现手写、选择、擦除等多种功能，以及可以实现手写、选择、擦除等多种功能之间的快速切换。具体的说，在书写操作模式下，根据实时输入的触控信息，若判断符合两指选择判定条件，则退出书写操作模式，切换进入选择操作模式，若判断符合五指擦除判定条件，则退出书写操作模式，切换进入擦除操作模式；在选择操作模式下，根据实时输入的触控信息，若判断符合单指书写判定条件，则退出选择操作模式，切换进入书写操作模式，若判断符合五指擦除判定条件，则退出选择操作模式，切换进入擦除操作模式；在擦除操作模式下，根据实时输入的触控信息，若判断符合单指书写判定条件，则退出擦除操作模式，切换进入书写操作模式，若判断符合两指选择判定条件，则退出擦除操作模式，切换进入选择操作模式。如此，无需另外点击功能按钮进行功能切换，即可通过相应的触控手势实现手写、选择、擦除等多种功能之间的快速切换，操作简便，响应速度快，使用极为便利。
本发明的实施例还提供了一种模式切换装置，其内部结构如图6所示，主要包括：
触控信息获取模块601、触控信息处理模块602、模式确定模块603 以及模式切换模块604。
其中，上述触控信息获取模块601用于检测用户输入的触控信息。
上述触控信息处理模块602用于对上述触控信息进行处理得到手势操作信息。
上述模式确定模块603用于确定所述手势操作信息是否符合预先设定的至少一个触控条件之一。
在本发明的实施例中，上述触控条件包括如下判定条件之一或其任意组合：单指书写判定条件、两指选择判定条件以及五指擦除判定条件。
上述模式切换模块604用于在所述手势操作信息符合预先设定的一个触控条件时，根据所述触控信息符合的触控条件进行模式切换。
例如，在符合单指书写判定条件时，上述模式切换模块604将调用书写功能，进入书写操作模式；在符合两指选择判定条件时，上述模式切换模块604将调用选择功能，进入选择操作模式；而在符合五指擦除判定条件时，上述模式切换模块604将调用擦除功能，进入擦除操作模式。
基于同一方面构思，本发明实施例还提供了一种电子设备，其结构如图7所示，包括存储器701、处理器702；存储器701和处理器702通过总线连接；存储器上存储有可在处理器上运行的计算机程序703，所述处理器执行所述程序时实现如上述任意一实施例所述的模式切换方法。
上述实施例的电子设备用于实现前述实施例中相应的方法，并且具有相应的方法实施例的有益效果，在此不再赘述。
基于同一方面构思，本发明实施例还提供了一种计算机可读存储介质，其上存储有计算机指令，在处理器执行上述计算机指令时实现如上述任意一实施例所述的模式切换方法。
本发明实施例的模式切换方法和装置，通过对输入的触控信息进行处理及判断，若符合单指书写判定条件，则进入单指书写操作模式，若符合两指选择判定条件，则进入两指选择操作模式，若符合五指擦除判定条件，则进入五指擦除操作模式。通过对实时输入的触控信息进行处理及判断，以执行相应的操作，可实现书写、选择、擦除等多种功能之间的快速切换，而无需通过操作功能按钮进行功能切换，操作方便，响 应迅速，用户使用极为方便。例如，用户在触摸输入设备上进行单指书写时，不必等待两指选择、五指擦除手势的识别结果，可快速进入书写操作模式；同时，使用两指选择或是五指擦除功能时，无需通过点击相关功能按钮等方式进行切换，从而无需打断手写过程，可通过两指选择、五指擦除的触控手势方式，快速切换至相应功能，实现交互目的。
上述实施例的装置用于实现前述实施例中相应的方法，并且具有相应的方法实施例的有益效果，在此不再赘述。
所属领域的普通技术人员应当理解：以上任何实施例的讨论仅为示例性的，并非旨在暗示本公开的范围(包括权利要求)被限于这些例子；在本发明的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本发明的不同方面的许多其它变化，为了简明它们没有在细节中提供。
另外，为简化说明和讨论，并且为了不会使本发明难以理解，在所提供的附图中可以示出或可以不示出与集成电路(IC)芯片和其它部件的公知的电源/接地连接。此外，可以以框图的形式示出装置，以便避免使本发明难以理解，并且这也考虑了以下事实，即关于这些框图装置的实施方式的细节是高度取决于将要实施本发明的平台的(即，这些细节应当完全处于本领域技术人员的理解范围内)。在阐述了具体细节(例如，电路)以描述本发明的示例性实施例的情况下，对本领域技术人员来说显而易见的是，可以在没有这些具体细节的情况下或者这些具体细节有变化的情况下实施本发明。因此，这些描述应被认为是说明性的而不是限制性的。
尽管已经结合了本发明的具体实施例对本发明进行了描述，但是根据前面的描述，这些实施例的很多替换、修改和变型对本领域普通技术人员来说将是显而易见的。例如，其它存储器架构(例如，动态RAM(DRAM))可以使用所讨论的实施例。
本发明的实施例旨在涵盖落入所附权利要求的宽泛范围之内的所有这样的替换、修改和变型。因此，凡在本发明的精神和原则之内，所做的任何省略、修改、等同替换、改进等，均应包含在本发明的保护范围之内。
