Description

一种控制方法及装置 技术领域
本文涉及但不限于通信领域，具体涉及一种控制方法及装置。
背景技术
智能手表的基本功能是提供时间显示，但是目前智能手表的表盘显示方向都是固定的，使得相关技术的智能手表存在以下缺陷：
第一、当佩戴者自己查看智能手表时，由于智能手表带在手上，需要调整手臂使表盘显示方向能更好的供人观看，而这需要手臂一直保持一种姿势，时间长了会引起酸痛。
第二、在给除佩戴者以外的其他人查看智能手表时，相对他人来说表盘是反方向的不便于观看，为了便于他人观看，需要佩戴者调整手臂并且观看者需要侧身才能实现。
第三、智能手表可佩带在左手或者右手，为了使佩戴者查看方便，就需要调整手表电源(power)键的方向，这对于不同习惯的佩戴者会带来一定的麻烦。
第四、当佩戴者将智能手表取下查看时，需要竖立着查看，而有时候放在桌面上观看时最好是利用表带做支撑横立着观看。
因此，相关技术的智能手表采取的固定表盘显示方向给用户查看带来一定的不便。
另外，手机是方形的，只需要调整两个方向利用重力传感器比较容易识别，而手表需要实现表盘360度的旋转。同时，当手机平躺着的时候，重力传感器会失去作用，而手表是戴在手上的，一般观看的时候是平躺着的，所以在手表上使用重力传感器调整表盘显示方向是不可行的。

在阅读并理解了附图和详细描述后，可以明白其它方面。
附图说明
图1为实施例一中的控制方法的流程图；
图2和图3为实施例二中的坐标示意图；
图4为实施例三中的控制装置的结构示意图一；
图5为实施例三中的控制装置的结构示意图二。
具体实施方式
下面将结合附图和具体实施例对本发明实施例的技术方案进行详细说明。需要说明的是，在不冲突的情况下，本文中实施例及实施例中的特征可以相互任意组合。
实施例一
如图1所示，本实施例提供一种控制方法，应用于终端设备，所述方法包括：
步骤S11：当终端设备检测到预设的触发条件时，检测所述终端设备上的接触点；
步骤S12：根据所述接触点的作用位置调整所述终端设备的显示界面的旋转角度。
可选地，步骤S12具体可以通过以下方式实现：

可选地，在本实施例中，根据检测到的接触点的作用位置计算得出所述接触点的移动方向和移动角度可以通过以下方式实现：获取所述接触点的作用位置的起点坐标、终点坐标以及所述显示界面的中心点坐标；根据所述起点坐标、终点坐标以及中心点坐标计算得出所述接触点的移动方向和移动角 度。
可选地，在本实施例中，终端设备检测到预设的触发条件包括：终端设备检测到的压力的压力值满足预设条件并且满足预设条件的压力的持续时间大于或等于预设时间阈值；其中，预设条件为所述压力的压力值大于或等于预设的压力阈值。
以智能手表为例，如果用户需要调节手表的显示界面的旋转角度，可以通过持续一定时间和力度的压力触发进入界面旋转角度的调节状态。例如，用户以一定的力度持续按压3秒可以触发界面调整模式。当触发进入界面旋转角度的调节状态后，需要检测用户作用于手表的接触点，根据这个接触点作用的位置和角度确定手表的显示界面如何旋转。
此外，终端设备检测到预设的触发条件还可以包括：所述终端设备接收到预定的语音信息。
上述技术方案可以使得终端设备的显示界面旋转任意角度。以智能手表为例，可以使得对于任何查看方向，表盘都能调整到一个最佳的方位供用户查看，这样就不需要佩戴者自己查看或者给他人查看时刻意调整保持手臂的姿势以便更好观看手表，提高了用户的体验度。
此外，上述技术方案通过采用一种压力感应屏来改变目前触摸屏的交互方式(轻触和长按)。由于智能手表设计的按键不如手机多，所以交互时没有手机方便。而压力传感屏会给用户的交互体验带来一种新的方便交互方式。在不改变手表的外观下新增一种交互方式，可以实现在查看手表的任何时候都可以调整手表表盘的显示方向，而不需要增加其他按键或者进入特定的设置界面，提高用户体验。
实施例二
下面以智能手表为例进一步说明本发明实施例的技术方案。
本实施例中，智能手表设置有压力传感器，能够识别用户的手或者其他接触的东西的按压力的大小，并将这种有一定压力的操作与普通轻触操作区分开。
智能手表的表盘旋转需要特定的触发机制，避免误操作，同时操作尽可 能简单方便。如果在观看时我们觉得表盘方位不太适合，那么我们希望立刻能调整，而不是进入特定的界面设置。可以通过手指(或者其它物体东西)用力按压屏幕，当屏幕下的压力传感器检测到压力值大于某一设定的值，并持续一定的时间(防止碰撞造成的误操作)，如果手指还接触屏幕，那么就会触发转动表盘显示方向的功能。这时手指不能离开，要保持接触但是可以放松，当手指离开屏幕时系统就会关掉这个功能，恢复原样。
当设备收到满足触发机制的事件响应时，即压力传感器检测到压力值大于某一设定的值并持续一定的时间，软件系统会在显示界面做一些提示用户系统进入旋转表盘显示方向的显示(如显示区域变的小一些)。此时用户手指不能离开屏幕，如离开就会退出这种操作模式。但是用户手指可以放松为轻触，然后用户可以顺时针或者逆时针移动手指，系统根据手指的实时位置计算手指移动的方向和角度，然后调整表盘显示方向，即表盘也会跟着手指移动的方向旋转。表盘的旋转角度相比手指移动的角度，可快可慢，可以通过实验找到一个最佳比率，也可以通过设置由用户自己调节。当用户通过移动手指使表盘显示旋转到理想的方向，放开手指就会退出旋转表盘显示模式，表盘显示也会恢复原样。
在本实施例中，智能手表可以采用压感屏，在触摸屏和液晶显示器(LCD，Liquid Crystal Display)的中间加入可以检测用力按下的传感器，传感器的信号可以传输到智能手表的主板和中央处理器进行处理，智能手表的软件侧可以收到用力按压的事件响应以及坐标信息等。
软件侧的底层系统实时监听压力传感器的压力大小，当压力值大于某个设定的值并保持一段时间，同时触摸屏能监测到有触摸，满足触发响应的条件，那么底层系统将事件上报给上层系统。上层系统做出相应的响应，如表盘显示区变小等，告知用户系统进入表盘显示方向调整模式。只要用户手不离开屏幕就不会退出这种模式，用户可以朝两个方向：顺时针和逆时针，移动手指。在移动的过程中系统可以根据触摸位置来判断手指移动的方向和角度，那么表盘显示以同样的方向和角度调节。
下面针对手指移动的方向和角速度的计算做进一步的说明：
如图2和图3所示，假设手表圆心的坐标为O(X0，Y0)，手指的上一个 接触点坐标为A(X1，Y1)，手指当前的接触点坐标为B(X2，Y2)。那么向量
Figure PCTCN2016074469-appb-000001
从A点移动到B点，旋转的夹角θ可以通过向量的数量积来计算：
Figure PCTCN2016074469-appb-000002
不管是逆时针还是顺时针，可以通过向量的向量积来判断。
将向量
Figure PCTCN2016074469-appb-000003
和
Figure PCTCN2016074469-appb-000004
扩展到三维空间向量为
Figure PCTCN2016074469-appb-000005
Figure PCTCN2016074469-appb-000006
那么两个向量的向量积为：
Figure PCTCN2016074469-appb-000007
由于向量
Figure PCTCN2016074469-appb-000008
的方向与
Figure PCTCN2016074469-appb-000009
和
Figure PCTCN2016074469-appb-000010
符合右手规则，所以当(X1-X0)*(Y2-Y0)-(Y1-Y0)*(X2-X0)为正时为逆时针方向，为负则为正时针方向。
如果出现极限情况，例如手指滑动的太快，检测到的两点间移动的角度大于180度，那么系统会认为与向反方向滑动至一个小于180度的地方产生的效果是一样的。如果正好等于180度，那么可以根据两点的坐标不相等来与0度区分。
上面的压感设备可以使用压感屏，也可以使用其他类似红外、生物电等传感器实现的压力感应技术。触发机制还可以采用语音识别，或者特定的设置界面。
实施例三
