具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
图1为一个实施例中终端的内部结构示意图。如图1所示，该终端包括通过系统总线连接的处理器、存储器和显示屏。其中，该处理器用于提供计算和控制能力，支撑整个终端的运行。存储器用于存储数据、程序、和/或指令代码等，存储器上存储至少一个计算机程序，该计算机程序可被处理器执行，以实现本申请实施例中提供的适用于终端的模式切换方法。存储器可包括磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)等非易失性存储介质，或随机存储记忆体(Random-Access-Memory，RAM)等。例如，在一个实施例中，存储器包括非易失性存储介质及内存储器。非易失性存储介质存储有操作系统、数据库和计算机程序。该数据库中存储有用于实现以上各个实施例所提供的一种模式切换方法相关的数据，比如可存储加速度验证特征、生物验证特征等。该计算机程序可被处理器所执行，以用于实现本申请各个实施例所提供的一种模式切换方法。内存储器为非易失性存储介质中的操作系统、数据库和计算机程序提供高速缓存的运行环境。显示屏可以是触摸屏，比如为电容屏或电子屏，用于显示终端的界面信息。该终端可以是手机、平板电脑或者个人数字助理或穿戴式设备等。
本领域技术人员可以理解，图1中示出的结构，仅仅是与本申请方案相关的部分结构的框图，并不构成对本申请方案所应用于其上的终端的限定，具体的终端可以包括比图中所示更多或更少的部件，或者组合某些部件，或者具有不同的部件布置。如该终端还包括通过系统总线连接的传感器，传感器可以是加速度传感器、陀螺仪中的一种及以上，用于对终端的姿态信息进行检测，比如可用于检测终端的位置数据、转动角度等。
本申请所提供的模式切换方法可以应用于支持不同用户使用的同一终端，且可以在不同用户模式间进行切换，不同的用户(用户A、用户B)对应于不同的用户模式，即一个用户对应一种用户模式(用户A对应于一种用户模式、用户B对应于另一种用户模式)。
图2为一个实施例中模式切换方法的流程图。本实施例中的模式切换方法，以运行于图1中的终端上为例进行描述。如图2所示，模式切换方法包括步骤202至步骤208。
步骤202，当处于主用户模式时，检测第一切换信号。所述第一切换信号包括终端的姿态变化信号。
主用户模式和次用户模式是一组相对的概念，二者的区别在于主用户模式具有比次用户模式更高的终端资源控制和访问权限(即终端使用权限)。
一般来说，终端处于主用户模式时，对终端上存储的数据拥有最高的设置和访问控制权限，可以使用终端的所有资源等。终端处于次用户模式时，允许查看部分信息 资料，使用终端的部分功能，而不允许使用短信、安装未知应用等。例如，次用户模式可以是现有的访客模式，主用户模式则是非访客模式。
需要说明的是，主次用户模式的数量和权限划分不限于此。用户还可以自行配置两种不同权限的用户模式，其中权限高的模式即为主用户模式，权限较低的模式即为次用户模式。
第一切换信号包括终端姿态变化信号，终端姿态变化信号用于表征终端的移动和转动等动作，终端的姿态变化包括终端上下左右移动、翻转、翻转和移动的组合等细节性动作。
终端姿态变化信号可包括转动姿态变化信号，通过陀螺仪(Gyro-sensor，又叫角速度传感器)可检测终端的转动情况并生成相应的转动姿态变化信号。终端上的陀螺仪芯片具体可以包括微机电陀螺仪(MEMS Gyroscope)、激光陀螺仪(Ring Laser Gyroscope，RLS)等。图3为一个实施例中终端姿态变化示意图。如图3所示，终端可以是手机320，通过用户手指340使手机320沿箭头340方向翻转(向右翻转)。手机320内置的陀螺仪芯片(图中未示出)检测手机320的翻转动作以产生相应的手机转动姿态变化信号。
终端姿态变化信号可以包括移动姿态变化信号，通过加速度传感器检测终端的上下左右移动情况以生成相应的移动姿态变化信号。结合图3，通过用户手指340使手机320沿箭头360方向平移，此时手机320内置的加速度传感器(图中未示出)可以检测到手机320的移动动作并产生相应的手机移动姿态变化信号。
重新结合图2，步骤204，根据第一切换信号从主用户模式切换至次用户模式；主用户模式具有比次用户模式更高的终端使用权限。
终端使用权限可以包括使用隐私应用的权限、使用金融应用的权限、下载删除文件的权限以及使用数据网络的权限。其中，隐私应用可以包括短信应用，微信、微博这类社交应用以及相册应用等；金融应用可以包括银行应用、支付宝等；下载删除文件的权限包括删除全部或部分文件，以及下载大小超过一定阈值的文件等。
从主用户模式切换至次用户模式的过程包括终端权限的降低，例如，本来再主用户模式下所具有的开启金融应用的权限，在切换至次用户模式后，终端不再具有该权限。具体过程包括通过终端上的处理器将第一切换信号与预设的姿态密码相匹配。若匹配成功，则从主用户模式切换至次用户模式，若不成功，则不切换。
步骤206，当检测到包括生物特征信号的第二切换信号时，根据第二切换信号切换回主用户模式。
第二切换信号包括生物特征信号，生物特征信号基于生物特征识别技术而产生的用于识别身份的信号，所谓生物特征识别技术是利用人的生理特征或行为特征，来进 行个人身份的鉴定。生物特征信号的类型可包括指纹特征、声纹特征、面部特征、虹膜特征、静脉分布特征中的至少一种。
从次用户模式切换至主用户模式的过程包括终端权限的提高，例如，本来在次用户模式下不具有开启金融应用的权限，在切换至主用户模式后，终端具有开启权限。具体过程包括通过终端上的处理器将第二切换信号与预设的生物密码相匹配。若匹配成功，则从次用户模式切换至主用户模式，若不成功，则不切换。
本实施例中的模式切换方法，通过验证终端的终端姿态变化而退出主用户模式进入次用户模式，再根据生物特征识别技术退出次用户模式进入主用户模式。从而采用隐蔽性较强的验证方式进入次用户模式，保证切换过程不易被他人察觉；再配合采用识别准确率高的生物验证方式进入主用户模式，保证了主用户模式的隐私数据不易泄露。
具体地，本实施例中的模式切换方法可以使得用户出借手机时，只需将手机以特定的规则移动和/或翻转即可切换为访客模式，避免借手机的人感觉受到他人猜疑防备，并且后续通过指纹、虹膜等生物验证才能退出访客模式，避免借手机的人碰巧移动翻转手机而退出访客模式，进而导致用户的隐私泄露。
进一步地，本申请的模式切换方法可以应用于支持多个用户使用的同一终端，且可以在多个用户模式间进行切换，不同的用户可分为主用户和次用户两类，多个主用户(用户A1、用户A2)对应不同的主用户模式，多个次用户(用户B1、用户B2)对应不同的次用户模式。
在一个实施例中，根据第一切换信号从主用户模式切换至次用户模式的步骤，包括：将所述第一切换信号与预设的至少两个姿态密码相匹配；确定与第一切换信号相匹配的姿态密码所对应的次用户模式；从主用户模式切换至所述对应的次用户模式。
具体地，次用户模式的数量不限，一个终端上可以有至少两个次用户模式，每个次用户模式配置有对应的姿态密码，当第一切换信号与某个次用户模式的姿态密码相匹配时，选择进入该次用户模式，而不进入其他不匹配的次用户模式。
具体过程包括：终端获取第一切换信号，将第一切换信号与预设的至少两个姿态密码相比较后，确定与第一切换信号相匹配的姿态密码所对应的次用户模式，并从当前的主用户模式切换至所述相对应的次用户模式。例如，预先将表征终端上下摇动两次的姿态信息设置为第一次用户模式的姿态密码，将表征终端左右晃动两次的姿态信息设置为第二次用户模式的姿态密码。于是，终端上下摇动和左右摇动将分别进入第一、第二次用户模式。
本实施例提供的模式切换方法，通过为不同的次用户模式配置不同的姿态密码，简化了选择进入多个次用户模式中的某一个次用户模式的操作步骤，提高了用户体验。
在一个实施例中，将第一切换信号与预设的至少两个姿态密码相匹配步骤，包括：获取第一切换信号对应的输入姿态密码；利用最大匹配算法将至少两个姿态密码分别与输入姿态密码进行校验。
具体过程包括：终端获取第一切换信号，解析第一切换信号，获取第一切换信号对应的输入姿态密码，该输入姿态密码可以是根据当前用户输入操作生成的字符串序列，将输入姿态密码与终端内至少两个预先保存的用户姿态密码利用最大匹配算法进行校验。其中，最大匹配算法主要包括正向最大匹配算法、逆向最大匹配算法、双向匹配算法等。其主要原理都是切分出单字串，然后和词库进行比对，如果是一个词就记录下来，否则通过增加或者减少一个单字，继续比较，一直还剩下一个单字则终止。当存在与输入姿态密码相同或相似度满足阈值的用户姿态密码时，标识输入第一切换信号的用户具备切换模式的权限，并确定出与该用户姿态密码对应的次用户模式，且从当前的主用户模式切换至相对应的次用户模式。
在一个实施例中，根据第二切换信号切换回主用户模式的步骤，包括：
检测第二切换信号的生物特征类型；生物特征类型包括指纹、声纹、面部、虹膜、静脉分布类型中的至少一种。
根据生物特征类型，确定与第二切换信号对应的主用户模式。
从次用户模式切换回对应的主用户模式。
具体地，主用户模式的数量不限，一个终端上可以包括至少两个主用户模式，不同主用户模式配置的生物特征密码类型不同。
具体过程包括：终端获取第二切换信号，检测第二切换信号的生物特征类型，将第二切换信号与相同生物特征类型的生物密码相匹配，若匹配成功，则进入该生物密码对应的主用户模式，若失败，则不进入主用户模式。例如当指纹特征验证通过时，进入第一主用户模式，声纹特征验证通过时，进入第二主用户模式，第一、第二主用户模式是不同的用户模式。
本实施例提供的模式切换方法，通过不同类型的生物特征验证，进入不同的主用户模式，从而简化了选择切换回多个主用户模式中的某一个主用户模式的操作步骤，提高了用户体验。
在一个实施例中，当处于主用户模式时，检测第一切换信号的步骤，包括：当处于主用户模式时，通过外界的可穿戴设备检测第一切换信号，以及接收检测到的第一切换信号。
终端处于主用户模式时，通过与终端连接的可穿戴设备检测第一切换信号，终端进而接收检测到的第一切换信号并判断第一切换信号是否包括特定的终端姿态变化特征。终端可以包括手机，外界的可穿戴设备可以包括与手机连接的耳机、智能手表、 智能手环等。此时，检测第一切换信号的设备改为耳机手表或手环等，手机则是用于接收检测到的第一切换信号。如图4所示，2.4GHz无线耳机420与手机440无线连接，用户头部460运动导致耳机420上下左右移动以及倾斜，此时，耳机420上配置的陀螺仪装置和加速度传感器(图中未示出)检测到耳机420的姿态变化信号，接着通过无线传输方式将该信号传输至手机440，手机440进而对第一切换信号是否包括特定的终端姿态变化特征进行检测。
本实施例提供的模式切换方法，通过验证与终端连接的可穿戴设备的姿态变化，控制终端从主用户模式切换至次用户模式，从而提高了验证过程的隐蔽性。
图5为一个实施例中根据第一切换信号从主用户模式切换至次用户模式的流程图。如图5所示，根据第一切换信号从主用户模式切换至次用户模式包括步骤502至步骤508。
步骤502，分析第一切换信号对应的角速度变化特征；角速度变化特征包括角速度方向变化特征或角速度大小变化特征。
在其中一个实施例中，控制终端内部的陀螺仪生成第一切换信号，第一切换信号携带角速度变化特征。具体过程如下：通过终端的处理器接收手机陀螺仪产生的第一切换信号，分析第一切换信号，获得角速度的方向和大小变化特征。如检测到终端旋转了360度，或者，检测到终端先顺时针旋转50度再逆时针旋转50度。另一方面，可以通过手机陀螺仪检测终端旋转的速度。如终端是否在1s内旋转了180度；进一步结合时间信息，可以检测终端是否在旋转了90度后，暂停一端时间，接着再继续旋转90度。
步骤504，判断角速度变化特征与验证特征之间的偏差是否大于偏差阈值。
若是，则执行步骤506，从主用户模式切换至次用户模式。否则，执行步骤508，不从主用户模式切换至次用户模式。
验证特征是一个预设的数据，该数据可以预存在终端的非易失性存储器中，也可以预存在系统服务器上。通过将验证特征预存在服务器上可以在更换手机后，将服务器上备份的验证特征直接导入新手机中，避免要重新设置验证特征的繁琐步骤。验证特征可以在终端上进行初始设置或者修改，或者从服务器获取更新后的验证特征以替代原先存储的验证特征。
验证特征可以是一个或多个预设的旋转角度数据，还可以包括旋转角度大小和旋转方向的组合数据，还可以包括旋转角度、旋转方向和时间的组合数据。该数据的设置可以是用户通过触控操作输入某个数字，还可以是输出显示多个数值供用户选择，接收用户选择指令后，确定选择的数值作为预设的验证数据。如验证特征包括表征终端旋转90度的数据。
判断偏差的方式可以包括，首先对角速度变化在时间上进行积分计算以获得终端旋转的角度，若当前终端旋转的角度小于预设的角度，则判定偏差为负值；若当前终端旋转的角度大于预设的角度，则判定偏差为正值。
偏差阈值代表当前检测到的终端的旋转角度变化与预设的旋转角度之间的偏差允许范围。例如，验证特征中预设的角度为90度，由于偏差阈值为-10度，则只要用户将终端旋转角度超过80度，判定大于偏差阈值，允许从主用户模式切换至次用户模式。若增大偏差阈值为0度，则终端旋转角度超过90度时，才判定大于偏差阈值。理论而言，偏差阈值不可以超过验证特征中预设的角度。由此可见，若预设的偏差阈值越小，则终端从主用户模式切换至次用户模式的过程越敏感，但误触发的几率也更大。若预设的偏差阈值越大，则从主用户切换至次用户模式的要求更严格，误触的几率越小。偏差阈值可以是通过在实验室进行大量实验计算以获得的适用于大多数人的数值范围，也可以用户根据自身需要自行设置。
从主用户模式切换至次用户模式的过程包括终端权限等级的降低，例如，切换后一些原本可在主用户模式下打开的应用，在次用户模式下将无法打开，具体的权限内容可参照前文，在此不再赘述。
本实施例中的模式切换方法，通过设置一定的偏差阈值，避免用户在旋转过程中人为预估角度失误，无法及时切换至次用户模式，导致隐私泄露。
在一个实施例中，还包括设置所述验证特征的步骤，包括：
接收验证设置指令，进入设置状态；在设置状态下，根据因终端的终端姿态变化所产生的姿态变化信号生成验证特征。接受结束指令，根据结束指令退出设置状态。
验证设置指令可以根据用户在触控屏上的触控操作产生，还可以根据特定条件自动生成。特定条件可以是用户处于终端初始化设置阶段，此时自动生成验证设置指令，进入设置状态。验证指令可以在终端上生成，还可以是从外界接收。
在其中一个实施例中，记录设置状态的开启时长；当开启时长到达预设时间时，自动生成结束指令。
结束指令可根据用户操作生成，还可以设置状态开启一段时间后自动生成结束指令，以避免终端长时间处于设置状态。
终端所处的设置状态通过终端接收验证设置指令而开启，以及，通过终端接收结束指令而结束。在设置状态下，终端上显示相应的界面或根据语音信息等方式提示用户当前处于设置状态下，用户在此状态下可对终端进行旋转、平移等操作。在设置状态结束后，处理器分析终端旋转所产生的最大旋转角度，将该最大旋转角度设置为验证特征。另一方面，分析终端平移所产生的最大位移，并将该最大位移设置为验证特征。该验证特征为旋转和平移的组合。还可以是用户在多个设置状态下对终端进行旋 转操作，处理器分析各个设置状态下的最大旋转角度，获取平均最大旋转角度，并将其设置为验证特征。
例如，在设置状态下，用户将终端进行多个方向的旋转操作。重新结合图3，例如，用户以终端的较长边为轴线旋转(沿箭头340方向)，接着以终端的较短边为轴线旋转(沿箭头380)，检测旋转产生的两个最大旋转角度和对应的两个旋转方向，将两个最大旋转角度和两个旋转方向都设置为验证特征。
本实施例中的模式切换方法，通过将设置状态下产生的姿态变化信号作为验证特征，从而简化了设置验证特征的步骤。
在一个实施例中，模式切换方法还包括步骤602至步骤604.
步骤602，检测终端的屏幕状态，所述屏幕状态包括灭屏状态和亮屏状态；
屏幕状态包括灭屏状态和亮屏状态。具体地，可以通过Power Manager Service检测屏幕是否被点亮的方式，确定终端处于亮屏状态或熄屏状态。当power接收到亮灭屏调用后，会先进行设置手机wakefullness状态，之后发送亮灭屏广播通知其他应用手机处于亮屏还是灭屏状态。
检测到终端处于灭屏状态时，进而检测终端所处的用户模式。终端灭屏状态时所处的用户模式，可根据最近一次灭屏时终端所处的用户模式来决定。例如，若最近一次灭屏时，终端处于主用户模式下，则灭屏状态下的终端处于主用户模式；若最近一次灭屏时，终端处在次用户模式下，则灭屏状态下的终端处于次用户模式。在另一个例子中，还可以设置为，无论最近一次灭屏时，终端处于主或次用户模式，灭屏后的终端都会处于主用户模式下。
步骤604，在灭屏状态下，根据所述第一切换信号，由灭屏姿态切换至亮屏姿态并解除屏幕锁定。
在灭屏状态下，检测第一切换信号，当接收到第一切换信号时，控制屏幕点亮。
一般情况下，点亮后的屏幕处于锁屏状态。锁屏状态是指当用户输入正确的解锁信息后、终端上的屏幕才能被成功解锁的状态。
本实施例中，第一、第二切换信号不仅可作为终端主、次用户模式间的切换触发信号，还可作为锁屏状态下的解锁信息。在接收到第一、第二切换信号后，锁屏状态被自动解除。
在一个实施例中，所述由灭屏姿态切换至亮屏姿态并解除屏幕锁定步骤之前，所述方法还包括：根据最近一次灭屏时终端所处的用户模式获取所述用户模式；当所述用户模式为主用户模式时，接收并检测所述第一切换信号；根据所述第一切换信号将所述用户模式切换至所述次用户模式。
解除锁屏状态的步骤可以设置在切换至次用户模式步骤后进行，因为若还未切换 至次用户模式(如访客模式)就解锁的话，容易暴露用户隐私。可以理解的是，在解除锁屏状态之前还有一个模式检测步骤，即检测当前的用户模式是否已切换至次用户模式，若接收到第一切换信号以及检测到用户模式为次用户模式，则终端自动解除锁屏状态。
本实施例提供的模式切换方法，考虑到次用户模式具备的权限较低，为简化解锁操作，在次用户模式下终端的解锁信息可以简单化。即根据终端的姿态变化将终端从主用户模式切换至次用户模式的同时，还可以根据该姿态变化实现自动解锁屏幕。极大程度上简化了用户操作。
具体地，当手机处于锁屏状态时，有人来借手机，此时手机主人可以将手机以预设的方式翻转两周，此时手机即切换至访客模式并完成屏幕解锁。从而既保护了用户隐私又简化用户操作。
在其中一个实施例中，所述方法包括：获取所述主用户模式下加载的桌面主题信息；从所述主用户模式切换至所述次用户模式后，控制所述次用户模式下加载所述桌面主题信息。
具体地，手机处于亮屏状态，有人来借手机，此时手机主人通过输入第一切换信号，如将手机以预设的方式翻转两周，此时手机即切换至访客模式。切换前后，手机桌面主题保持一致，从而既保护了用户隐私又保证切换过程不易被他人察觉避免尴尬。
应该理解的是，虽然图1-6的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图1-6中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
图7为一个实施例的模式切换装置的结构框图。如图7所示，模式切换装置700包括：
第一检测模块701，用于当处于主用户模式时，检测第一切换信号。第一切换信号包括终端的终端姿态变化信号。
第二检测模块702，用于检测包括生物特征信号的第二切换信号。
处理模块703，用于根据第一切换信号从主用户模式切换至次用户模式。主用户模式具有比次用户模式更高的终端使用权限。处理模块703还用于当检测到第二切换信号时根据第二切换信号切换回主用户模式。
本实施例中的模式切换装置700，处理器703通过接收第一检测模块701的第一切 换信号而退出主用户模式进入次用户模式，处理器703再通过接收第二检测模块703的第二切换信号退出次用户模式进入主用户模式。本申请采用隐蔽性较强的验证方式进入次用户模式，保证切换过程不易被他人察觉。再配合采用识别准确率高的验证方式进入主用户模式，保证了主用户模式的隐私数据不易泄露。
具体地，本实施例中的模式切换装置700可以使得用户出借手机时，只需将手机以特定的规则移动翻转即可切换为访客模式，避免借手机的人感觉受到他人猜疑防备，并且后续采用指纹验证才能退出访客模式，避免借手机的人碰巧翻转手机导致退出访客模式，进而导致用户的隐私泄露。
在一个实施例中，处理模块包括：
比较单元，用于将第一切换信号与预设的至少两个姿态密码相匹配。
选择单元，用于确定与第一切换信号相匹配的姿态密码所对应的次用户模式。
切换单元，用于从主用户模式切换至所述对应的次用户模式。

在一个实施例中，处理模块包括：
类型识别单元，用于检测第二切换信号的生物特征类型；生物特征类型包括指纹、声纹、面部、虹膜、静脉分布类型中的至少一种。
选择单元，用于根据生物特征类型，确定与第二切换信号对应的主用户模式
切换单元，从次用户模式切换回对应的主用户模式。
本实施例中的模式切换装置，通过不同类型的生物特征验证，进入不同的主用户模式，从而简化了选择切换回多个主用户模式中的某一个主用户模式的操作步骤，提高了用户体验。
在一个实施例中，处理模块还用于当处于主用户模式时，通过外界的可穿戴设备检测第一切换信号，以及接收检测到的所述第一切换信号
本实施例中的模式切换装置，通过验证与终端连接的可穿戴设备的姿态变化，控制终端从主用户模式切换至次用户模式，从而提高了验证过程的隐蔽性。
在一个实施例中，处理模块，包括：
分析单元，用于分析第一切换信号对应的角速度变化特征。角速度变化特征包括角速度方向变化特征或角速度大小变化特征。
判断单元，用于判断角速度变化特征与预设的验证特征之间的偏差是否大于设定的偏差阈值。若是，则从主用户模式切换至次用户模式。否则，不从主用户模式切换至次用户模式。
本实施例中的模式切换装置，通过设置一定的偏差阈值，避免用户在旋转过程中 人为预估角度失误，无法及时切换至次用户模式，导致隐私泄露。
在一个实施例中，处理模块，包括：
启动单元，用于接收验证设置指令，进入设置状态。
生成单元，在设置状态下，根据因终端的终端姿态变化所产生的状态变化信号生成验证特征。
退出模块，用于接收结束指令，退出所述设置状态。
本实施例中的通过将设置状态下产生的姿态变化信号作为验证特征，从而简化了设置验证特征的过程。
