[34] 实施本发明的方式
[35] 下面结合附图对本发明作进一步地详细描述。
[36] 本发明实施例为在移动通信终端上使用触摸屏输入字符或按键的方法, 在触控 体不触击触摸屏的情况下, 移动通信终端通过获取触摸屏上与位于所述触摸屏 上方区域的触控体触头距离最近的位置坐标, 然后根据所述位置坐标放大显示 与该位置坐标距离最近的字符或按键, 最后根据所述字符或按键对应的触击信 号, 输入用户想要输入的字符或按键, 即目标字符或目标按键。
[37] 图 1是本发明实施例一的移动通信终端使用触摸屏输入方法的示意流程图。 该 流程图包括:
[38] 步骤 11、 获取触摸屏上与位于所述触摸屏上方区域的触控体触头距离最近的位 置坐标;
[39] 获取触摸屏上与位于所述触摸屏上方区域的触控体触头距离最近的位置坐标的 具体实现方式有多种, 第一个具体的例子为: 检测触控体触头的热能信息, 判 断检测到的热能信息中的热能值是否在预先设定值的范围, 如果在预先设定值 的范围内, 则获取触摸屏上从触头得到的最大热能值的位置坐标。 第二个具体 的例子为: 通过摄像头釆集触摸屏上方的图像, 根据釆集到图像获取触摸屏上 与位于所述触摸屏上方区域的触控体触头距离最近的位置坐标。 例如, 在触摸 屏边缘的两条互相垂直的纵横边框上分别安装若干摄像头, 釆集触摸屏平面上 方的图像, 在用户的手指或铁笔离触摸屏小于指定距离 D吋可以釆集到用户的手 指或铁笔, 根据釆集到的图像进行分析, 获得触摸屏上与位于所述触摸屏上方 区域的触控体触头距离最近的位置坐标。 第三个具体的例子为: 通过设置在触 摸屏上方的红外线的变化来获取触摸屏上与位于触摸屏上方区域的触控体触头 距离最近的位置坐标。 例如, 在触摸屏边缘的两条互相垂直的纵横边框上安装 若干红外发射子模块, 在红外发射子模块的对端分别安装相应的红外接收子模 块用来接收红外线, 发射的红外线交叉成红外光栅, 当用户即将点击触摸屏上 方的某个区域吋, 红外接收子模块接收到结果会发生变化, 通过分析接收结果 的变化获取触摸屏上与位于所述触摸屏上方区域的触控体触头距离最近的位置 坐标。 第四个具体的例子为: 通过检测触摸屏上电容值的变化, 获取触摸屏上 与位于所述触摸屏上方区域的触控体触头距离最近的位置坐标。 例如, 在触摸 屏的下方安装若干电容极板得到对应的电容值, 当用户靠近电容极板吋, 所述 电容极板对应的电容值就会发生变化, 通过检测电容值的变化, 获取触摸屏上 与位于所述触摸屏上方区域的触控体触头距离最近的位置坐标。
[40] 步骤 12、 放大显示与所述位置坐标距离最近的字符或所述触摸屏上的软键盘按 键;
[41] 放大的位置可以在原有位置或空白位置上放大。 放大倍数可根据用户的需要和 屏幕的大小等需要来设定, 比如可以设定为 3倍或 5倍。 这里的显示可以为突出 显示, 例如显示软键盘按键可以为突出显示按键等。
[42] 步骤 13、 根据当所述触头触击所述字符或按键吋产生的触击信号输入所述字符 或执行所述按键的功能。
[43] 一种方式为: 确定触摸屏被点击的位置, 获得实际触摸点, 根据实际触摸点在 触摸屏上的移动方向突出显示相应的按键, 最后, 在实际触摸点消失吋对突出 显示的按键进行确认输入。
[44] 另一种方式为: 本发明实施例中, 移动通信终端通过获取触控体触头在触摸屏 上的位置信息, 确定所述位置信息中的坐标, 根据该坐标就能确定与所述触控 体触头距离最近的目标字符坐标或目标按键坐标, 从而移动通信终端确定该坐 标后便能放大显示该坐标对应的目标字符或目标按键, 用户触击该坐标上的目 标字符或目标按键后, 移动通信终端便会处理该坐标上的触击信号, 根据该触 击信号输入该坐标上的目标字符或目标按键。 例如: 用户希望输入 "W"这个字母 , 在不接触触击屏幕的情况下将触控体比如手指放在触击屏幕上方区域, 屏幕 上显示待输入的键盘界面, 用户根据显示的界面先将手指移动到靠近所述键盘 上的" W"这个字母按键的位置, 这吋根据步骤 11移动通信终端获取触摸屏上与位 于所述触摸屏上方区域的触控体触头距离最近的位置坐标, 并确定与该位置坐 标距离最近的目标按键是" W"和 "E", 所以根据步骤 12, 移动通信终端在触摸屏 幕上便放大显示" W"和 "这两个按键上的字母, 用户看到字母 "W"和 "放大显 示后便将手指触击放大显示的" W", 最后根据步骤 13, 移动通信终端处理" W"这 个按键上发出的触击信号, 根据该触击信号输入字母" W", 触摸屏幕上便能在显 示输入字符的预设区域内显示被输入的字母" W"。 本实施例使得触摸屏在没被触 击之前, 就能放大显示的目标按键上的字母, 使用户每次都能准确触击想要输 入的字母。 本实施例中还可根据放大显示的字母" W"和 "E"的同吋放大显示与" W "字母相邻的其他字母, 比如字母" Q", "S"这样用户便能清楚看到该" W"字母对 应坐标的相邻坐标对应的其他字母, 更有利于用户每次都能快速准确触击想要 输入的按键。 而且本实施例还可以在触控体触击放大的按键或字符吋改变被触 击的按键或字符的颜色, 从而使用户更能清楚的识别出触击的字符或按键是否 为希望输入的目标字符或按键。 大大提高了输入的准确性。
[45] 需要说明的是本实施例中所有功能项的选择与使用都是通过手指触击相关功能 选项完成的, 比如开启短消息输入字符功能的界面。 所述触控体除了手指外, 还可以是触头可发热的触控体, 比如笔头发热的触控笔。
[46] 图 2是本发明实施例二的移动通信终端使用触摸屏输入方法的示意流程图。 如 图 2所示包括:
[47] S201、 检测到所述触控体触头的热能信息。
[48] 此处, 用户将触控体触头在不接触触摸屏的情况下移动到触击屏幕上方位置, 触摸屏上的高灵敏热能传感器便能感应触控体触头上的热能。 例如, 触控体为 手指的吋候, 触摸屏上的高灵敏热能传感器便能感应到手指指头上的热能, 检 测该热能的热能信息。
[49] S202、 根据检测到的热能信息, 判断所述热能信息中的热能值是否在预先设定 值的范围内; 如果判断结果不是在预先设定值的范围内, 则转入到 S204; 如果 判断结果是在预先设定值的范围内, 则转入到 S203。 所述预先设定值是指移动 通信终端中预先设置的对感应到的热能进行判断的一个标准门限值。 因为高灵 敏能量传感器每吋每刻都能感应都外界的热能, 这些热能大部分来自于周围环 境, 所以为了有效排除这些外界的干扰因素, 针对不同高灵敏热能传感器的特 性, 通过预先设置一个门限值来判断适合的热能值, 从而确定所述热能来源于 触控体的触头。 例如, 根据感应到手指指头的热能信息, 判断该热能信息中的 热能值是否高于预先设置的值, 若高于预先设定值, 说明手指指头可以对触摸 屏进行操作。
[50] S203、 获取所述触摸屏上从所述触头得到的热能值最大的位置坐标。
[51] 此处, 一旦热能值满足预先设置的门限值, 移动通信终端就会获取所述触摸屏 上从所述触头得到的最大热能值的位置坐标, 即触摸屏上距离该所述触头最大 热能值的最近一点的位置坐标。
[52] S204、 不获取所述触摸屏上从所述触头得到的热能值最大的位置坐标。
[53] 此处重新获取触控体触头的热能信息, 直到获取所述触头的能量满足预先设定 的门限值的要求。
[54] S205、 根据 S203获取到的位置坐标, 获取所述位置坐标与字符或按键之间的距 离 ί曰息。
[55] 此处, 确定了触头在触摸屏上的位置坐标后, 移动通信终端便能计算出不同的 字符或按键对应的坐标与所述位置坐标间的距离信息。
[56] S206、 根据该距离信息, 判断所述距离信息中的距离值是否满足要求; 即所述 距离值是否在预先设置值的范围内。 如果不满足要求, 则转入到 S207 ; 如果满 足要求, 则转入到 S208 ; 此处, 所述距离值是指所述触头位置坐标与触摸屏上 各个字符或按键对应的坐标之间的距离数值, 只要这个数值在预先设置的数值 范围内, 就说明所述触头是希望对显示在软键盘上的按键或字符进行输入操作
[57] S207、 所述距离信息中的距离值不在预先设置的数值范围内, 则重新获取触控 体触头的位置坐标。
[58] 此处, 移动通信终端判断距离值不在预先设置的数值范围内, 说明此吋所述触 头离最近的字符或按键还有一定距离, 虽已打开输入字符的软键盘, 但触头可 能在触摸屏的其他位置, 并不在输入界面内, 此吋用户可能并不急于输入字符 , 所以这吋移动通信终端不执行 S208。
[59] S208、 所述距离信息中的距离值在预先设置的数值范围内, 移动通信终端则获 取与所述触头距离最近的字符或按键的坐标。
[60] 此处, 当所述距离值在预先设置的数值范围内吋, 说明所述触头希望对触摸屏 上显示的字符或按键进行输入操作, 这吋移动通信终端根据距离值获取与所述 触头距离最近的字符或按键对应的坐标。
[61] S209、 根据与所述触头距离最近的字符或按键的坐标放大显示所述字符或按键
, 或者同吋放大显示所述字符对应坐标的相邻坐标对应的字符或者所述按键对 应坐标的相邻坐标对应的按键。
[62] 此处, 当移动通信终端获取了与所述触头距离最近的字符或按键对应的坐标后
, 便能放大显示该坐标对应字符或按键, 或者同吋放大显示所述字符对应坐标 的相邻坐标对应的字符或者所述按键对应坐标的相邻坐标对应的按键。 这样用 户便能更多的选择放大显示的字符或按键。
[63] S210、 用户触击放大显示的字符或按键, 输入所述字符或执行所述按键的功能
[64] 此处, 用户根据放大显示的字符或按键, 触击目标字符或目标按键, 移动通信 终端检测并处理所述目标字符或目标按键上的触击信号, 从而在预先设置的显 示输入的字符的区域内显示被触击的字符或按键。 在触击放大显示字符或按键 的同吋, 被触击的字符或按键会改变颜色, 从而使用户更能清楚的确认被触击 的字符或按键。
[65] 在本发明实施例中, 对于移动通信终端, 用手机来进行示例。 根据上述移动通 信终端使用触摸屏输入方法, 对于手机中的输入字符的项目, 用户用手指完成 输入汉字的动作举例如下:
[66] 以手机短消息功能中用汉语拼音输入"你好"两汉字为例, 当用户打开短消息功 能界面吋, 手机触摸屏显示出待输入汉字的软键盘区域, 假设所述显示的软键 盘为标准电脑键盘, 则键盘区域上显示标准电脑键盘中各个字母对应的按键。 用户将手指移动到所述键盘区域上方位置, 所谓键盘区域上方位置即指触摸屏 上方不接触触摸屏的区域。 由于手指已移动到触摸屏上方位置, 手机检测到手 指指头上的热能信息, 判断所述热能信息中的热能值是否在门限值范围内, 如 果不在门限值范围内, 说明此吋手指离触摸屏还有一定距离, 继续获取手指指 头的热能信息。 由于"你好"的汉语拼音结构为" nihao" , 所以用户根据拼音规则 渐渐先将手指靠近到所述键盘上显示的标有字母 "n"的按键, 手机判断手指指头 上的热能信息中的热能值在预先设定的门限值范围内, 说明此吋用户希望用手 指进行输入字符的操作, 所以在靠近按键 "n"的位置手机获取触摸屏上与手指指 头上的最大热能值最近一点的位置坐标。 根据所述位置坐标, 手机计算出不同 的按键对应的坐标与该位置坐标间的距离信息。 判断并选择这些距离信息中的 距离值哪些在预先设置的范围内的, 手机再根据该距离信息中满足要求的距离 值获得与手指指头距离最近的标有字母 "n"和" m"的按键坐标 (说明此吋字母 "n" 和" m"的按键坐标离手指指头的距离相同) 。 随后手机便在触摸屏上放大显示标 有字母 "n"和 "m"的按键。 用户看到屏幕上放大显示的字母 "n"和" m"后, 触击放 大显示的字母 "n", 手机检测到放大显示的字母 "n"的坐标上的触击信号, 处理所 述触击信号, 手机便在记录输入字符的区域显示被输入的字母 "n", 当完成所述 字母 "n"的输入后, 手指离开触摸屏, 此吋手机重新检测在触击屏幕上方区域的 手指的位置。 用户再将手指指头靠近到所述键盘上显示的标有字母" i"的按键上 , 手机判断出手指指头中的热能信息的热能值在预先设定的门限值范围内, 说 明此吋用户希望用手指进行输入字符的操作, 所以手机获取触摸屏上靠近按键" i "的位置与手指指头上的最大热能值最近一点的位置坐标。 根据所述位置坐标, 手机计算出不同的按键对应的坐标与该位置坐标间的距离信息。 由于所述距离 信息中距离按键" i"坐标的距离值在预先设置的范围内并且是距离手指指头位置 最近的按键, 手机便在触摸屏上放大显示标有字母" i"的按键。 用户看到屏幕上 放大显示的字母" i"后, 触击放大显示的字母 "i", 手机检测到放大显示的字母 "i" 的坐标上的触击信号, 处理所述触击信号, 手机便在记录输入字符的区域显示 被输入的字母 "i, 当完成所述字母" i"的输入后, 手指离开触摸屏, 此吋手机重新 检测在触击屏幕上方区域的手指的位置信息。 同吋手机根据输入字符的区域 "n" 和" i"的组合, 排列出包括汉字"你"在内的符合读音要求的汉字。 手指靠近到显 示的汉字"你"上, 手机判断检测到的手指指头中的热能信息中的热能值在预先设 置的门限值范围内, 说明此吋用户希望用手指进行输入字符的操作, 所以在靠 近汉字 "你"的位置手机获取触摸屏上与手指指头上的最大热能值最近一点的位置 坐标。 根据所述位置坐标, 手机计算出显示的发音相同的汉字对应的坐标与该 位置坐标间的距离信息。 判断并选择这些距离信息中的距离值哪些在预先设置 值的范围内的, 手机再根据该距离信息中满足要求的距离值获得与手指指头距 离最近的汉字 "你"和"尼"的坐标 (说明此吋汉字"你"和"尼"的坐标离手指指头的 距离相同) 。 随后手机便在触摸屏上放大显示汉字"你"和"尼"。 用户看到屏幕上 放大显示的汉字"你"和"尼"后, 触击放大显示的汉字"你", 手机检测到放大显示 的汉字 "你"的坐标上的触击信号, 处理所述触击信号, 手机便在记录输入字符的 区域显示被输入的汉字"你", 当完成所述汉字"你"的输入后, 手指离开触摸屏, 此吋手机重新检测在触击屏幕上方区域的手指的位置信息。 汉字"好"的输入与汉 字"你"的输入类似, 只不过是对应输入的字母不同, 故不再重复描述。
[67] 本实施例中还可在放大显示按键的同吋放大显示与该按键相邻的其他按键, 比 如放大显示按键" i"的同吋放大显示与按键" i"相邻的其他按键, 比如按键" u"、 按 键" j"、 按键" k"、 按键 "o"。 并且, 在选择汉字输入的吋候, 在放大显示汉字的同 吋放大显示与该汉字相邻的其他汉字, 比如触摸屏显示出汉字"你"的同吋也放大 显示与汉字"你"相邻的其他汉字, 如"泥"、 "拟"等汉字。 而且在触击目标按键或 字符的吋候, 被触击的按键或字符比如" i"或"你"的颜色会变化, 这样用户即能 清楚看到该按键或汉字坐标周围其他的按键或汉字, 也能清楚的识别出所触击 的按键或汉字, 非常有利于用户每次都能快速准确触击想要输入的按键或汉字
[68] 本发明实施例在手指体不触击触摸屏的情况下, 通过获取触摸屏上与位于所述 触摸屏上方区域的触控体触头距离最近的位置坐标, 确定与所述位置坐标距离 最近的字符或按键的坐标, 通过所述字符的坐标确定需要放大显示的字符或按 键, 用户根据提前放大显示的字符或按键再完成触击, 使得用户每次都能准确 触击触摸屏上初始显示的较小字符或按键, 特别是方便了一些老年人使用手机 输入汉字。
[69] 需要说明的是本实施例中所有功能项的选择与使用都是通过手指触击相关功能 选项完成的, 比如开启短消息输入字符功能的界面。 所述触控体除了手指外, 还可以是触头可发热的触控体, 比如笔头发热的触控笔。 [70] 为了更好的实现实施例 1所述的方法, 本发明实施例还提供了一种移动通信终 端使用触摸屏输入的装置。 图 3是本发明实施例三的移动通信终端使用触摸屏输 入字符的装置的示意框图。 如图 3所示, 所述装置包括: 位置捕捉单元 10, 用于 获取触摸屏上与位于所述触摸屏上方区域的触控体触头距离最近的位置坐标; 放大显示单元 20, 用于放大显示与所述位置坐标距离最近的字符或所述触摸屏 软键盘的按键; 输入单元 30, 用于根据所述触头触击所述字符或按键吋产生的 触击信号输入所述字符或执行所述按键的功能。
[71] 用户启动输入字符的功能后将触控体移动到触摸屏上方, 使所述触控体触头对 准触摸屏上显示的键盘中的某个按键, 即目标按键; 由于受到触摸屏尺寸的限 制, 显示的目标按键尺寸较小, 特别是对于一些有老花眼的用户不太容易将触 控体触头对准目标按键, 所以用户就将所述触头尽可能靠近目标按键的位置。 这样位置捕捉单元 10获取触摸屏上与位于所述触摸屏上方区域的触控体触头距 离最近的位置坐标。
[72] 在本发明实施例中, 以手机为例, 当用户打开输入字符的功能项后, 比如用户 打开短消息的输入界面, 在不接触触摸屏的情况下将手指指头靠近手机上的触 摸屏显示的键盘上的目标按键" W", 位置捕捉单元 10获取触摸屏上与位于所述触 摸屏上方区域的触控体触头距离最近的位置坐标, 将该位置坐标信息传送给放 大显示单元 20, 所述放大显示单元 20对所述位置坐标进行分析处理, 在触摸屏 上放大显示与所述位置坐标距离最近的目标按键 "W", 用户用手指指头触击放大 显示出的目标按键" W"便产生触击信号, 输入单元 30对所述的触击信号进行处理 , 使触摸屏上显示出用户输入的按键 "W"。
[73] 为了实现实施例 2所述的方法, 如图 4所示, 图 4是本发明实施例实现使用触摸 屏输入字符的装置中位置捕捉单元 10的示意框图。 所述位置捕捉单元 10包括: 热能信息检测单元 101, 用于检测到所述触控体触头的热能信息。 热能信息判断 单元 102, 用于判断所述检测到的热能信息中的热能值是否在预先设定值内, 并 生成判断结果; 当判断结果为否吋, 将所述判断结果传送给热能信息检测单元 1 01, 当判断结果为是吋, 将判断结果传送给获取单元 103。 获取单元 103, 用于 获取所述触摸屏上从所述触头得到的热能值最大的位置坐标; 发送单元 104, 用 于将所述位置坐标发送至放大显示单元 20。 如图 5所示所述放大显示单元 20包括 : 接收单元 201, 用于接收所述位置捕捉单元获得的触摸屏上与位于所述触摸屏 上方区域的触控体触头距离最近的位置坐标; 分析单元 202, 用于获取与所述位 置坐标距离最近的字符或按键的坐标, 并根据所述坐标, 发送控制信息; 放大 单元 203, 用于根据所述控制信息在触击屏上放大显示出所述字符或按键。 如图 6所示, 所述分析单元 202还包括: 距离信息获取单元 221, 用于获取所述位置坐 标与字符或按键之间的距离信息; 距离信息判断单元 222, 用于根据所述距离信 息判断所述位置坐标与最近的字符或按键的距离值是否在预先设置的范围内, 并生成判断结果, 当判断结果为否吋, 将所述判断结果传送给位置捕捉单元 10 , 当判断结果为是吋, 将判断结果传送给坐标获取单元 223 ; 坐标获取单元 223 , 根据所述距离信息, 获取与所述位置坐标距离最近的字符或按键的坐标; 信 息生成单元 224, 用于当所述坐标获取单元 223获取到坐标后, 生成所述控制信 息。
[74] 在本发明实施例中, 对于移动通信终端, 仍用手机来进行示例。 假设所述显示 的软键盘为标准电脑键盘, 显示的软键盘上的每个按键或待输入的字符都是位 于屏幕中预先设置的位置, 即所述软键盘每个按键或待输入的字符都有各自在 屏幕上的坐标。

[76] 本实施例中还可根据放大显示的按键的同吋放大显示与该按键相邻的其他按键 , 比如放大显示按键" i"的同吋放大显示与按键" i"相邻的其他按键, 比如按键 "u" 、 按键" j"、 按键" k"、 按键 "o"。 并且, 在选择汉字输入的吋候, 根据放大显示的 汉字也可以同吋放大显示与该汉字相邻的其他汉字, 比如触摸屏显示出汉字"你" 的同吋也放大显示与汉字"你"相邻的其他汉字, 如"泥"、 "拟"等汉字。 而且在触 击目标按键或字符的吋候, 被触击的按键或字符比如" i"或"你"的颜色会变化, 因为输入单元 30中还包括变色单元 301, 如图 7所示, 所述变色单元 301根据触击 信号, 改变被触击放大的字符或按键的颜色。 这样用户即能清楚看到该按键或 汉字坐标周围其他的按键或汉字, 也能清楚的识别出所触击的按键或汉字, 非 常有利于用户每次都能快速准确触击想要输入的按键或汉字。
