Description

一种实现浏览器中光标定位的方法及装置 技术领域
本发明涉及电子产品技术领域，特别涉及一种实现浏览器中光标定位的方法及装置。
 背景技术
目前几乎所有电视都是通过遥控器来控制操作浏览器，一方面，由于遥控器灵敏度低，使用遥控器来控制浏览器的操作极其不便；另一方面，遥控器将光标移动到链接点时需要进行多次按键才能操作浏览器，定位非常不准。现有技术中的电视机领域还公开了其他几种移动光标来控制浏览器的方式，例如通过无线鼠标来控制浏览器、通过将手机连接到电视上来控制浏览器、在遥控器上安装触控板来控制浏览器、通过晃动遥控器来控制浏览器、通过手势识别方式来控制浏览器等。但是这些方式都存在或多或少的不足；
1、通过无线鼠标来控制浏览器：使用无线鼠标在浏览器中移动光标虽然方便，但当退出浏览器时，又需用户使用遥控器进行操作，这样让用户使用多个设备操控电视，背离了简单易用、让用户轻松娱乐的原则；
2、通过将手机连接到电视上来控制浏览器：通过传屏将电视画面传到手机，用户在手机上操控电视，但是这种方式在网络环境差的情况下反应迟缓；并且有的手机屏幕较小，网页链接在手机屏幕上显得密密麻麻，不能准确点击链接；
3、在遥控器上安装触控板来控制浏览器：由于安装的触控板面积有限，在电视这样的大屏上移动光标需要多次滑动才能移动到目标链接区域，并且需要微调才能准确移到目标链接，操作较为繁琐；
4、通过动感应遥控器来控制浏览器：动感应遥控器也被称为“空鼠”，“空鼠”可使得光标能够随着遥控器的晃动而改变位置，但存在定位不准确的问题；
5、通过手势识别方式来控制浏览器：这种方式对于动作的规范性和操作距离都有要求，而且当有多人同时在做手势时，电视识别会受到很大的干扰，并且手势识别同样存在定位不准确的问题。
 技术问题
通过以上的分析，发现目前电视领域中的控制浏览器的方式都普遍存在定位不精准问题，并且上述的3、4、5都需要在原有的硬件上增加其他元器件才能实现，增加了生产成本。
技术解决方案
为了解决现有技术中控制浏览器中出现的定位不准确的问题，本发明提供了一种实现浏览器中光标定位的方法及装置。所述技术方案如下：

S3-3：判断Sa与Sb的差值是否小于预设长度，是则执行S3-5，否则执行S3-4；
S3-4：判断βb与βa的差值是否大于预设角度，是则执行S3-5，否则执行S3-6；
S3-5：将光标定位到夹角最小的链接点（a），执行链接点，返回S0；
S3-6：将光标定位到距离最短的链接点（b），执行链接点，返回S0。

 本发明的实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
实施例一
本发明实施例一提供了一种实现浏览器中光标定位的方法，如图1所示，包括：
S0：接收用户按键信息；
在本实施例中，当浏览器被用户打开后，开始执行S0；
S1：判断光标是否在浏览页面上，是则执行S2，否则返回S0；
S2：检测按键的类型，如为方向键则执行S3，如为确认键则执行S4，如为其他键则返回步骤S0；
具体的，本实施例中的方向键包括上键、下键、左键、右键；
S3：根据当前光标位置在浏览页面上设置第一扫描区域，根据方向键扫描第一扫描区域内的所有链接点，并根据用户的操作将光标定位到符合要求的链接点上，执行链接点，返回S0；
S4：根据当前光标位置在浏览页面上设置第二扫描区域，扫描第二扫描区域内的所有链接点，并将光标定位到距离当前光标位置最近的链接点上，执行链接点，返回S0。
如图2所示，本实施例的方法中所述S1与S2之间包括：
S1’：判断按键的类型是否为调用键，是则执行S1’’，否则执行S2；
本实施例中的调用键可以为快捷键（如确定键长按）或浏览页面上的调用键；
S1’’：通过自动识别浏览页面的每个主体区域，生成网页结构的缩略图，调出所述缩略图，当接收到用户对所述缩略图中的区域进行选择的信息时，将光标移动到与选择的所述缩略图中的区域对应的主体区域中，返回S0；
在本实施例中，一个浏览页面上可以有多个主体区域，当用户同时打开多个浏览页面时，通过S1’和S1’’将光标移动到某个浏览页面中具体的一个主体区域中，S3和S4中直接在主体区域中设置扫描区域，能更加准确的实现定位光标；
本实施例中的S4之前包括：S4’：判断光标是否已定位链接点，是则执行链接点，返回S0；否则执行S4。
在本实施例中，执行链接点即网页发生跳转，执行完链接点后可返回S0，进行下一次光标定位的操作。
在本实施例中， S3和S4中还包括：将光标定位标志置位；S4’具体为：判断光标定位标志位是否置位，是则光标已定位链接点，否则光标未定位链接点；
具体的，在本实施例中，结合具体的示例图来说明本实施例的实现方法，参照图3，为本实施例中通过自动识别浏览页面的每个主体区域，生成网页结构的缩略图，其中S101为浏览器页面，S102为生成的缩略图，此缩略图可由快捷键（如确定键长按）调出，也可在使用触控板遥控器等方式时点击S103（调用按钮）调出，用户选择缩略图中区域即可将光标移入浏览页面中对应区域中。这样可以有效减少用户将光标移到目标链接所需要的操作。
其中，S3的具体实现方案如图4所示，以光标当前位置为坐标原点O，生成一个坐标系，直线L1和L2互相垂直，分别与x轴成45°角和-45°角。L1和L2将光标所在的主体区域划分为四个区域Q1、Q2、Q3、Q4，与方向键中的右键、上键、左键、下键一一对应，例如Q1对应右键、Q2对应上键、Q3对应左键、Q4对应下键，当用户点击右键、上键、左键、下键时，将在Q1、Q2、Q3、Q4中扫描出来的所有链接点作为判断对象，即认为用户通过光标定位的目的链接点在这些链接点之中。例如，用户点击右键时，从图4中所示的区域Q1中扫描出所有链接点（用圆点标识），从所有链接点中找出与x轴夹角最小的a点和与原点O距离最近的b点，选取a点还是b点作为目标链接点的原则结合图5进行说明；
参见图5，S3的具体实现流程包括：
S3-1：根据当前光标位置设置所述第一扫描区域，根据方向键扫描所述第一扫描区域中的所有链接点；
S3-2：找出以光标当前位置为坐标原点且与x轴夹角最小的链接点（a）和离坐标原点距离最短的链接点（b）；将链接点与坐标原点之间的距离记为S，链接点与x轴的夹角记为β；
在本实施例中，设a点与原点距离为Sa，与x轴的夹角为βa；b点与原点距离为Sb（图5中虚线部分），与x轴的夹角为βb；
S3-3：判断Sa与Sb的差值是否小于预设长度，是则执行S3-5，否则执行S3-4；
S3-4：判断βb与βa的差值是否大于预设角度，是则执行S3-5，否则执行S3-6；
S3-5：将光标定位到夹角最小的链接点（a），执行链接点，返回S0；
S3-6：将光标定位到距离最短的链接点（b），执行链接点，返回S0。
在本实施例中，若Sa-Sb<预设长度，即a点与原点距离与b点与原点距离的差值在预设长度内，即a点与b点相差不远则选择a点；或者，即使两者与原点的距离的差值超出预设长度，但βb-βa>预设角度，即a点与x轴夹角比b点与x轴夹角小许多，仍然选择a点，其中预设长度和预设角度的具体数值都需要在实现时通过测试选定最佳数值。其他情况则选取b点坐位目标链接点，即若Sa-Sb≥预设长度并且βb-βa≤预设角度，则将光标定位到距离最短的链接点（b）。
其中，S4的实现过程如图6所示，将用户当前光标位置作为原点O，当用户点击确定键时，当前光标不在任何链接之上的情况下，在图6中正方形区域P中扫描出链接点（用圆点标识），其中c点离原点的距离Sc（图6中虚线部分）最小，则将光标移到c点之上。其中，正方形边长需要在实现时通过测试选定最佳数值。
在本实施例中，可将实现本实施例方法的程序设置在传统遥控器中或手机上的遥控器软件中进行工作，当用户通过传统遥控器或者手机遥控器软件打开浏览器后，自动定位链接功能立即开启（即开始执行S0）。若用户点击调用键或快捷键（如确定键长按）时，则自动识别浏览页面的每个主体区域并生成网页结构的缩略图，然后调出浏览页面主体区域的缩略图，用户选择要进入的主体区域，系统将光标移动到用户选择的主体区域中。若用户在实现光标定位过程中，如使用方向右键，则根据如图4所示的Q1区域中链接分布情况，判断用户意图，然后将光标定位到分析出来的符合用户意图的链接点上。
若用户使用触控遥控器、传屏、动作识别等方式操纵电视，若用户点击附图3所示的S103按钮，则调出网页缩略图供用户点选，将光标定位到用户选择的主体区域中。若用户做点击动作（等同于按确定键），则扫描图6所示P2区域中的所有链接，并将光标定位到与原点距离Sc最小的c点。
本发明实施例的方法自动定位光标，无论用户使用什么样的工具操控电视，只要能够向电视发送方向键、确定键，本发明都可自动将光标移到最近的、符合用户意向的链接点。这样的方式对操控电视的工具要求放宽，并且本发明解决了定位不准确问题，实现了智能电视浏览器操作方式的简单化、人性化，具有广阔的应用前景和实用价值。
