技术领域
本发明涉及终端控制领域，具体涉及一种终端界面内容的缩放控制方法及 装置。
背景技术
现有移动终端界面对于某些内容的展示， 例如网页或者图片， 常常由于其 展现对象的内容过大而超过了终端屏幕显示区域， 需要缩小展现对象，在观察 细节的时候需要放大展现对象。 目前，对于展现对象的缩放操作方法主要有两 种， 第一种是通过调用界面上的菜单进行操作，其缺点是需要键盘或者触摸屏 多次点击操作才能完成， 操作繁瑣， 效率不高， 同时界面菜单本身的设置也会 影响到展现的内容，此外也不容易以某精确点位为中心进行缩放控制； 第二种 是通过多点触摸屏进行操作， 即在触摸屏上滑动指头， 例如拇指和食指， 当两 个指头分离运动时放大内容， 当两个指头靠近运动时则缩小内容，该方式需要 多个指头的参与， 操作不便， 效率不高， 且无法以精确点位为中心进行缩放， 缺少了操作的精确度。
发明内容
本发明的第一目的是提出一种高效的终端界面内容的缩放控制方法。 本发明的第二目的是提出一种高效的终端界面内容的缩放控制装置。 为实现上述第一目的，本发明提供了一种终端界面内容的缩放控制方法及 装置， 包括： 感测终端在两个时刻间的位移； 根据位移对终端的界面内容进行 缩放控制。
为实现上述第二目的， 本发明提供了一种终端界面内容的缩放控制装置， 包括： 终端的位移探测单元， 用于感测终端在两个时刻间的位移； 终端的缩放 控制单元， 用于根据位移对终端的界面内容进行缩放控制。
本发明各个实施例中，通过感测终端在两点间的位移， 并根据该位移控制 界面内容的缩放， 操作简单方便， 不繁瑣， 提高缩放的效率。
附图说明
附图用来提供对本发明的进一步理解， 并且构成说明书的一部分， 与本发 明的实施例一并用于解释本发明， 并不构成对本发明的限制。 在附图中：
图 1为本发明的终端界面内容的缩放控制方法的实施例一流程图； 图 2为本发明的终端界面内容的缩放控制方法的实施例二流程图； 图 3为本发明的终端界面内容的缩放控制装置的实施例一结构图； 图 4为本发明的终端界面内容的缩放控制装置的实施例二结构图。
具体实施方式
以下结合附图对本发明的优选实施例进行说明，应当理解，此处所描述的 优选实施例仅用于说明和解释本发明 , 并不用于限定本发明。
方法实施例
图 1为本发明的终端界面内容的缩放控制方法的实施例一流程图。 如图 1 所示， 本实施例包括：
步骤 102: 感测终端在两个时刻间的位移；
步骤 104: 根据位移对终端的界面内容进行缩放控制；
本实施例通过感测终端在两点间的位移，并根据该位移控制界面内容的缩 放， 操作简单方便， 不繁瑣， 提高缩放的效率。
图 2为本发明的终端界面内容的缩放控制方法的实施例二流程图。 如图 2 所示， 本实施例包括：
步骤 201： 进入到终端内的浏览器或者图片查看器等类似内容查看程序， 浏览网页或者查看图片；
步骤 202: 激活终端的位移探测单元（详见图 3及图 4的解释说明）， 使 其进入待机状态， 准备开始工作；
步骤 203 : 判断触摸屏是否被点击 （即触摸信息）， 并在确定有点击时执 行步骤 204， 否则继续执行步骤 203;
步骤 204: 根据触摸信息确定在终端的界面内容上的选择点 , 即触摸点； 在确定选择点的同时触发位移探测单元开始工作（此时记为运动起始时刻， 即 为点击触摸屏的时刻， 当然， 具体操作时， 该用于开始探测位移的运动起始时 刻可以与该选择点的确定时刻独立 ,如可以先触摸终端界面以确定探测起始时 间， 也可以感测终端的运动， 将开始运动时作为探测起始时间， 省去为了确定 该探测起始时间的操作 )；
具体操作时，位移探测单元可以实时感测终端在运动起始时刻与各运动持 续时刻及运动停止时刻间的位移，也就是持续计算起始时刻与运动停止时刻前 (包括运动停止时刻 )之间的位移（相应地， 步骤 205不断地对界面内容进行 缩小或放大）， 或者感测终端在运动起始时刻与运动停止时刻间的位移， 也就 是仅计算两个点， 即起始时刻与运动停止时刻的位移（相应地， 步骤 205只在 运动停止时刻对界面内容进行缩小或放大）；
该位移探测单元可以为加速度传感器、 超声波探测器或摄像头中的任一 种； 以下对各种位移探测单元进行具体解释： 对于以加速度测量为基础的位移 探测单元， 考虑到用户在查看界面内容时的使用习惯， 即屏幕面向用户且移动 的方向为远离或靠近用户，可以设置加速度传感器的某一敏感轴平行于垂直于 屏幕的方向 （该方案考虑了用户的使用习惯， 为优选方案）， 这样该加速度传 感器在工作时，通过运算去除重力分量带来的影响，从而计算得到除重力以外 的外力所引起的在垂直于屏幕方向上的位移； 具体如下：
加速度传感器可以是三轴微机械加速度传感器（可以根据需要选择其他类 型的加速度传感器， 如两轴微机械加速度传感器， 此处不应解释为限定）， 在 静止状态下， 终端在空中的姿态为某一方向，通过三轴微机械加速度传感器三 轴输出的加速度值，分别计算出三轴与重力之间的夹角 若安装方向与 垂直于屏幕的方向平行的敏感轴（简称位移敏感轴） 的角度为 ）， 即为终端 在空中的初始姿态角度， 若终端在静止及移动的过程中， 没有旋转， 也就是终 端在静止及移动的过程中其姿态角度不变， 则在各移动时刻，位移敏感轴上的 加速度输出量减去重力加速度在角度 上的余弦分量后的值， 即为用于计算在 位移敏感轴方向上位移的加速度 (加速度与位移的关系为二次积分 ,具体操作 时可以采用各种逼近算法， 详见下一段的解释说明）；
如若考虑终端在移动过程中会发生旋转的情况 ,也就是终端在移动的过程 中其姿态角度发生改变的情况 ,可以利用陀螺仪（如三轴微机械陀螺仪等各种 陀螺仪）来计算动态姿态角度， 终端在空中的初始姿态角度如上段， 由加速度 传感器确定， 在运动过程中， 由三轴加速度陀螺仪输出角速度 在采样时间 点 （各位移时刻） 上的角速度值， 假设其初始角速度值为 ，采样时间是 TW ..Tn, 对应个点的角速度值分别为《。， ，··· ， 各个点的旋转设为 ，W... , 三者关系具体如公式（1 )及（2)所示：
Figure imgf000005_0001
若 =0， 即初始旋转速度为零， 也就是用户保持终端在静止时不旋转， 依据 上述公式可以分别算出在各个轴上（加速度传感器的敏感轴） 的旋转的角度， 得到终端在任一时刻于空中的姿态角度，通过重力加速度和各姿态角度，求得 终端在任意时刻重力加速度在加速度传感器的各敏感轴的重力分量（可以设置 加速度传感器的各个敏感轴和陀螺仪的各敏感轴重合）， 这样， 三轴微机械加 速度传感器的各个敏感轴的加速度输出量减去对应的重力分量即可得其他外 力在各敏感轴方向上作用在终端上的加速度" (此处以在位移敏感轴上的加速 度及位移为例进行说明）， 具体如下； 假设终端初速度值为 e。， 采样时间是 Τ0,Ί ,Τ2 .Τη, 对应各时间点的加速度值分别为"。， ^，…""， 各时间点的速 度设为 。，^ .. " , 则可以用如下公式表示对应关系：
0=C0+r0* 0 (3 )
νη = ν0 + ^^Τ Τ^+α2(Τ2_Τ^+,^αη^Τη Τη_^^ η≥ 1 (4) 对应各个时间位的位移可以有不同的逼近方式， 如：
τ s„ -τη_λ)
Figure imgf000005_0002
η> 1 (6)
具体操作时可以设置 c。的值为 0,即用户在按下屏幕的时候终端的移动速度为 0; 本领域技术人员可以理解， 加速度传感器的敏感轴的方向可以任意设置， 不限于平行于垂直于屏幕的方向；也可以由加速度传感器上多个敏感轴上的位 移来控制界面内容的缩放；
对于超声波探测器，具体操作时可以安装在终端面板和屏幕的同侧，通过 发射超声波， 当在不同时刻碰到参照物（如人脸）以后获得不同时刻终端与参 照物（如人脸， 需要指出的是， 为了保证计算精度， 各个时刻碰到的参照物需 是同一参照物）之间位移， 通过超声波探测器自有性质， 可以实时输出反射波 和入射波之间的时间差，从而得到起始时刻与运动停止时刻前（包括运动停止 时刻）之间的位移， 具体操作时， 考虑到人手在操作终端过程中， 位移不可能 发生突变， 若出现超声波发生突变的情况， 可以设置停止计算位移；
对于摄像头，通过实时摄像跟踪目标物的图像在运动起始时刻与运动操作 时刻（该运动操作时刻可以包括终端停止运动前的各持续运动时刻）间的缩放 比例 （例如人脸或眼睛等）， 并根据各缩放比例与距离的预设对应关系计算得 到终端在运动起始时刻与运动操作时刻间的位移 ,或者根据终端的摄像头感测 目标物的图像在运动起始时刻与运动操作时刻间的缩放比例直接对终端的界 面内容进行缩放控制；
具体如：假设在运动起始时刻，摄像头锁定脸部几个特殊点位，例如眼睛， 鼻子或嘴巴等， 并分别计算各个特殊点位的轮廊的像素点位大小或者轮廊面 积， 当终端或者锁定物体运动时，通过实时监测特殊点位的大小或者轮廊面积 等， 求得一个比例因子， 从而推断出位移大小比例因子， 从而进行终端界面内 容缩放； 具体操作时， 还可以设置当特殊点位完全丢失， 以丢失之前最后比例 因子停止缩放， 或者当某些特殊点位丢失， 以剩下特殊点位进行计算；
步骤 205: 位移探测单元将测定的位移发送给传送单元（详见图 3及图 4 的解释说明， 如操作系统）， 再由该传送单元分发给缩放控制单元（如浏览器 或者图片查看器等）进行界面内容的缩放控制， 同时， 在实现以选择点为中心 进行缩放时 , 触摸屏将选择点的信息经该传送单元发送至缩放控制单元；
具体地： 缩放控制单元根据位移及在终端的界面内容上的选择点，对终端 的界面内容以选择点为中心进行缩放控制；缩放控制单元根据位移的方向控制 对终端的界面内容进行缩小或放大操作，并根据位移的值控制缩小或放大终端 的界面内容的比例； 如， 面向人脸运动时放大或者缩小， 可以根据实际需要设 置， 还可以设置控制开关选择两种不同的控制方式， 一种是面向人脸放大， 一 种是面向人脸方向缩小； 位移值控制缩放的比例可以根据实际需要设置，如运 动 1cm以内不进行缩放， 运动 1cm到 5cm以内每增力口 lcm缩放比例为 5%, 当超过 5cm缩放比例为 10%; 步骤 206: 判断是否为运动终止时刻； 并在判定为运动终止时刻时通知位 移探测单元停止工作， 停止界面内容的缩放， 结束操作， 以及在判定不是为运 动终止时刻时， 执行步骤 204;
具体操作时，运动起始时刻与运动终止时刻的获取方式可以自由设定，如 初始点击触摸屏时确定为运动起始时刻 ,当实时缩放到一定阶段达到用户满意 的缩放效果时，用户手指抬离触摸屏的时刻设定为运动终止时刻或者在点击后 用户直接离开触摸屏， 以用户再次点击的时刻为运动终止时刻。
本领域技术人员可以理解，对终端的界面内容以选择点为中心进行缩放控 制实现了以精确点为中心进行缩放， 为优选方案；根据位移的方向控制对终端 的界面内容进行缩小或放大操作为优选方案，实际操作时还可以设置在某个位 移值内进行缩小的操作，在另一个位移值内进行放大的操作；根据位移的值进 行缩放的比例控制也为优选技术方案，具体操作时，还可以用预设的比例值进 行缩放；实时感测终端在运动起始时刻与各运动持续时刻及运动停止时刻间的 位移， 并实时的进行界面内容的缩放也为优选的方案，便于用户实时确知是否 达到缩放目的；将选择点的确定时间作为位移探测的时间也为优选方案；此外， 本方案的核心在于根据位移控制界面内容的缩放，故可以不限定在终端移动时 进行感测位移， 也就是说， 感测位移不建立在确定具体感测时间的基础上， 可 以在任意时刻进行位移感测 , 进而进行界面缩放控制。
本实施例通过在带有触摸屏的终端上增加位移探测单元，实现了终端能实 时感知自身在两时刻间运动位移大小， 并通过该位移实现缩放控制，且还实现 了在移动的同时以触摸屏的接触点位为中心点进行对象内容的缩放，本实施例 中的方法操作简单， 快捷， 能更精确的控制缩放比例， 具有更好的人机体验效 果。
