联系信息输入方法及系统
技术领域
本发明属于字符输入及图像处理技术领域, 涉及一种字符输入方法, 尤其涉 及一种基于光学字符识别技术的联系信息输入方法; 同时, 本发明还涉及一种联 系信息输入系统。 背景技术
近年来, 随着手机、 PDA、 掌上游戏机、 导航仪等电子设备的日益普及, 作 为和这些电子设备进行人机交互的各种手段,字符输入法是其中最基本也是最常 用的手段。
目前常用的字符输入法主要有两类: 一类是键盘输入法, 利用智能设备自带 的键盘, 用户通过一次或多次敲击键盘的按钮, 来输入期望输入的字符。 比如 Nok ia公司生成的 S40 , S60系列手机, Moto的 Q系列手机中所采用的键盘字符 输入法。 图 1是一个手机键盘输入法的一个实例。 这类方法的优点是: 用户可以 利用拇指进行单手输入操作,每次按键都能给用户明确的反馈, 通过定义键盘按 键的组合可以实现各种语言的输入。 缺点是: 用户输入一个字符需要多次击键, 并且用户需要学习才能知道一个字符对应的按键组合才能输入该字符 ,比如利用 拼音来输入一个中文字符;而且输入不同类型的字符时,用户需要切换输入模式。
另一类是触摸屏输入法,这类输入法通过点击智能设备触摸屏上的虚拟键盘 实现文字输入, 或者直接在触摸屏上用触笔书写期望输入字符, 输入法将用户书 写的笔迹识别转换成字符来实现文字输入(图 2是基于 Windows Mob i le触摸屏 虚拟键盘输入法的一个实例 )。 虚拟按键文字输入与前述的键盘输入法优缺点相 似; 手写输入法的优点是用户无须学习字符的按键组合, 直接在触摸屏上书写该 字符即可实现字符输入, 其缺点是输入速度比较慢; 一般需要双手操作, 一手持 握设备, 另一只手执触笔书写字符; 书写比较潦草时容易识别错误, 将进一步降 低输入速度; 输入不同类型的字符时, 用户同样需要切换输入模式。 随着智能设备的功能越来越丰富, 在原来具备的拨打电话, 发送短信 /邮件 等功能的基础上, 更多的网絡功能添加到了智能设备上, 比如访问搜索引擎, 网 络地图, 网络博客等等。 而人们在日常的生活当中经常会遇到带特定联系信息的 印刷品 ,比如名片上的电话, ema i 1,手机号;书籍报刊杂志广告上的电话, ema i 1 , 网址, 地址等等。 当人们对这些印刷品传递的内容感兴趣时, 便会通过智能设备 中的应用程序来访问这些联系信息。 比如拨打电话, 发送邮件, 访问网站, 查找 地图位置等等。这时便需要将这些联系信息逐个字符的输入到应用程序的编辑框 (如电话拨号盘, 如图 3; ema i l收件人, 如图 4 ; 浏览器地址栏, 如图 5; 地图 搜索地址栏, 如图 6; 等等), 对于比较长的信息比如 URL和地址信息, 经常时 多种类型的字符混排 (比如中文和数字, 英文和数字等等), 输入时还需要经常 切换输入模式;而且在输入过程中注意力还要不断在智能设备输入法和印刷文字 内容之间反复切换。 总之这个过程是一个麻烦而且耗时的过程。 发明内容

其中, 拍摄预览界面中设定的定位标识用以指定拍摄的联系信息。 所述定位 标识可以为定位框、 划线 (但划线、 双划线、 多划线), 或者用符号标记始末位 置。
优选地,本方法还可以包括通过一定位标识调节模块调节定位标识形状的步 骤; 用户根据拟输入文本的范围、通过所述定位标识调节模块调节定位标识的位 置或 /和形状。
较佳地, 当电子设备的显示单元为触摸显示单元时, 用户可以根据拟输入文 本的范围、 通过在所述触摸显示单元上发起触摸动作, 输入定位标识的位置或 / 和形状; 所述定位标识调节模块获取上述触摸动作,根据该触摸动作设定定位标 识的位置或 /和形状。
步骤 A、 步骤 B的顺序可互换。
【步骤 C】利用光学字符识别技术分析识别图像中位于预览界面中定位标识 附近的文字内容, 然后提取出符合当前编辑框内容属性的联系信息字符串。
若当前编辑框的内容属性为电话号码,则选择识别出的联系信息字符串中全 为数字的字符串, 或者还包括电话号码中可能包含的符号; 电话号码中可能包含 的符号包括: '+' , "- " , ' (, , '), , '*,, ' Χ ' , "ext. " ;
