Description

一种基于触摸屏的按键判定方法和装置
技术领域
本发明涉及互联网技术领域, 尤其涉及一种基于触摸屏的按键判定 方法和装置。 发明背景
随着电子产品技术的发展和人们的对电子产品便携的需求, 电子产 品越来越趋于小型化, 例如: 掌上电脑、 PDA ( Personal Digital Assistant, 个人数字助理)和手机等手持电子产品。 由于电子产品的小型化, 其显 示屏幕也随之小型化, 因此越来越多的电子产品采用触摸屏以节约电子 产品的面积。
触摸屏向用户提供虚拟键盘, 通过用户点压虚拟键盘上对应的按键 而进行输入, 通常用户在一次点击操作中包括以下动作: 按下, 移动和 抬起, 或按下和抬起。 终端在执行动作时, 根据用户点击位置的坐标, 判定需要执行的功能。 由于每一个按键区域面积有限, 用户点击时, 由 于轻微移动会造成按下点和抬起点的坐标值是不同的, 且按下点和抬起 点可能分别属于不同的按键区域, 此时终端无法获知用户所要输入的按 键。 现有技术中提供了以下两种方法:
方法一、 触摸展划线输入法
该方案中, 用户在触摸屏上的划线终点作为有效点来确定被输入的 按键, 当使用者由于各种原因未能准确点击待输入按键时, 只需向输入 按键的方向划线, 直至划线终点进入待输入按键的有效范围, 即可正确 输入, 从而有效避免了错误点击时必须抬笔, 删除错误输入后重新输入 的麻烦, 大大减少了错误输入的可能, 有效的提高了输入速度。 方法二、 根据使用频率调整按键区域大小的方法。
该方案中, 根据按键使用次数的高频率, 低频率信息动态调整按键 的有效区域, 放大高频率按键的有效区域同时在争议的区域默认为使用 次数高频率的按键有效, 当触摸屏幕按键进行输入时, 确定触摸屏按键 的输入是否是有效输入, 提高触摸屏按键的输入效率。
在实现本申请的过程中, 发明人发现现有技术至少存在如下问题: 对于划线输入法, 以使用者在触摸屏上的划线终点作为确定按键的 唯一判定条件, 仅通过抬起点坐标判断用户行为, 可能会因为触笔抬起 时的移动造成对用户行为的误判。 对于根据使用频率调整按键区域大 小, 由于根据频率调整按键区域,会影响用户点击不常用按键的准确率, 如杲多个频率相近的按键排列在一起, 会使此方案方法无效。 发明内容

下面将结合本发明中的附图, 对本发明的技术方案进行清楚、 完整 地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的 实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出创造 性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
如图 1所示, 为本发明实施例提供的一种基于触摸屏的按键判定方 法, 具体包括以下步骤:
步驟 101、 检测等待按压操作; 步骤 102、 当检测到按压操作时, 获取当前按压点的位置信息和扩 展信息, 直至检测到该次按压操作停止为止;
步驟 103、 根据该次按压操作中按压点的位置信息和扩展信息判断 该次按压操作对应的按键;
步骤 104、 根据该次按压操作对应的按键进行输入。
其中, 对于每一个按压点, 位置信息是用于标识当前按压点在触摸 屏中的位置, 优选地, 以触摸屏中的某一点为原点建立坐标系, 以当前 按压点在该坐标系中的对应坐标标识该按压点的位置信息, 当然也可以 为其他用于标识位置的信息, 此处不做限制。 扩展信息是与当前按压点 的位置信息对应的相关信息, 用于与位置信息配合判断该次按压操作对 应的按键, 可以是与该位置信息对应的按键的判定区域, 或与位置信息 对应的按压点的时间信息等, 或者这些的结合。 进一步地, 获取到多个 按压点各自的位置信息和扩展信息后, 还可以对多组位置信息和扩展信 息进行统计处理, 获得其他判断按压操作所需的信息, 例如: 根据按压 点的位置信息获取对应的按键后, 对对应同一按键的按压点进行计数, 得到对应同一按键的按压点数, 以及对应同一按键的按压点中时序上的 第一的按压点和最后一个按压点获得该按压操作在该按键的持续时间。 上述扩展信息仅为本发明实施例中优选的实施方式, 凡是用来判断按压 操作对应的按键的信息均属于本发明的保护范围, 例如: 连续按压的按 键之间的关联关系, 如经判断, 第一个按压操作对应的按键为 "s" , 则 第二按压操作对应的按键可以为 "a" , 不可以为 "w" 等。
以下结合具体应用场景, 对本发明的技术方案进行详细阐述。 其中, 扩展信息为 "按键的判定区域" 和 "时间信息", 且根据按压点的位置 信息判断与按压点对应的按键时, 信息的获取过程与判断过程并行执 行。 如图 2所示, 为本发明实施例提供的一种基于触摸屏的按键判定方 法, 具体包括以下步骤:
其中, 以图 3所示的触摸屏虚拟键盘为例进行说明, 当然触摸屏虚 拟键盘的具体表现形式不应视为对本发明保护范围的限制, 此外本发明 的保护范围并不限于触摸展的虚拟键盘, 也同样适用于触摸屏中其他的 按压操作, 如: 点击文件夹等。 此时, 按键的判决区域与该按键的区域 相同, 如图 4所示, 其中阴影表示的区域为按键的判决区域。
步骤 201、 终端检测到按压操作, 获取第一个按压点的位置信息。 例如: 当用户在键盘上字母键 d区域内按下, 该按压点 1的位置如 图 5所示, 不妨以坐标表示, 设此时按压点 1的位置为 ( 150, 100 )。
步骤 202、 终端记录该按压点的位置信息和时间信息, 并根据该位 置信息所属的显示区域判断第一个按压点对应的按键。
例如:基于步骤 201中的假设,根据按压点 1的位置信息( 150, 100 ) 确定该按压点所属的显示区域为按键 d的显示区域, 进一步判断第一个 按压点对应的按键为按键 do
步骤 203、 获取第一个按压点对应的按键的显示区域, 并根据该显 示区域动态获取与第一个按压点对应的按键的判定区域。
具体地, 当判断第一个按压点对应的按键为 d时, 获取按键 d的显 示区域, 并根据该显示区域进行放大, 例如: 进行按比例动态放大。 优 选的, 将该显示区域扩大到按键的显示区域的 1.1倍, 得到判定区域。 此时周围按键的判定区域相应缩小。 需要说明的是, 仅判定区域发生变 化, 按键的显示区域保持不变。 其中, 判定区域是动态变化的, 当按压 点的位置离开当前的判定区域时, 该判定区域失效, 再根据按压点的后 续位置重新动态获取对应的判定区域。
例如: 当用户的按压点 1为位于按键 d所在的按键区域, 如图 6所 示, 此时按键 d的判定区域为由虚线勾勒的矩形所表示的覆盖范围, 此 时按键 r的判定区域也相应的缩小, 如右斜的阴影所示。
当然, 也可以为其他调整方式, 例如: 对按键的显示区域按照指定 的放大范围进行方法,如将按键的显示区域的宽度左右各增加 5微米等。 具体的调整范围不应视为对本发明保护范围的限制。
优选地, 终端根据该判定区域判断该按压点所属按键, 并通过屏幕 显示按键提示, 以使用户感知当前所按的按键。 具体地, 通过显示一些 辅助提示信息, 方便用户知道按下的按键, 例如: 以按键高亮, 按键反 色, 按键放大, 气泡提示等方式显示提示信息。 如图 7所示, 将按键反 色或气泡提示为例进行说明。
步骤 204、 获取后续按压点的位置信息, 并结合最新获取的判定区 域进行判断。
当用户进行按压时, 系统会连续不断发送当前按压点信息, 由于触 笔或者手指的微小移动会造成按下点坐标的变化, 因此按压点通常不只 单一的一个点, 而是由许多点组成。
本发明实施例中以后续按压点为第二按压点, 最新获取的判定区域 为根据第一按压点获取的判定区域为例进行说明。 具体地, 若第二个按 压点的位置信息在由第一按压点获取的判定区域内, 则判定第二个按压 点对应的按键与第一个按压点对应的按键相同; 否则, 根据第二个按压 点的位置信息所属的显示区域重新判断第二个按压点对应的按键。
步骤 205、 判断按压动作是否完成, 即按压点是否被抬起。
如果按压点没有被抬起, 则转到步骤 204;
如果按压点被抬起, 转到步骤 206。
步驟 206、 终端根据按压点的位置信息, 时间信息, 以及根据各个 位置信息获取的对应的按键判断该次按压操作对应的按键。 终端将接收到的一系列按压点的信息列表, 具体格式如表 1所示。 表 1、 信息列表
Figure imgf000014_0001
个位置信息对应的按键判断该次按压操作对应的按键具体包括以下步 骤:
步骤 2061、 对于所获取的对应的每一个按键, 根据对应的位置信息 获取与该按键对应的按压点数, 并根据按时序对应的最后一个按压点的 按压时间和第一个按压点的按压时间获取与该按键对应的按压的持续 时间。
步骤 2062、 根据所获取的每一个按键的按压点数和持续时间, 按照 预设的规则判断该次按压操作对应的按键。
需要说明的是, 步骤 206之前(即步骤 201至步骤 205 ), 也可以不 在位置信息获取的同时, 根据已获取的按压点的位置信息判断对应的按 键, 而是当该次按压操作完毕后, 再根据该次按压操作的所有按压点信 息进行按压点对应按键的判断和该次按压操作对应按键的判断。 此时, 步骤 206包括以下步骤: ( 1 )根据该次操作中产生的多个按压点各自的 位置信息和对应的时间信息分别判断与各个按压点对应的按键和对应 的按压时间; (2 )对于所对应的每一个按键, 根据对应的位置信息获取 与该按键对应的按压点数, 并根据按时序对应的最后一个按压点的按压 时间和第一个按压点的按压时间获取与该按键对应的按压的持续时间; ( 3 )根据所获取的每一个按键的按压点数和持续时间, 按照预设的规 则判断该次按压操作对应的按键。 其中, 按压点对应的按键包括以下两种情况:
( 1 ) 多个按压点对应同一按键。
例如: 如图 8所示, 按压点 1、 2、 3、 4和 5的位置仍然处于按键 d 的判定区域内, 其对应的按键均为按键 d。
( 2 ) 多个按压点对应不同的按键。
例如: 如图 9所示, 按压点 1、 2、 3和 4的位置属于按键 d的判定 区域, 对应的按键为按键 d, 而按压点 5的位置已经不属于按键 d的判 定区域, 此时对按压点 5按照上述方法确定判定区域, 如图 10所示, 按压点 5的位置属于按键 f的判定区域, 对应的按键为 f。 以下分别针对上述两种情况, 按照判决准则判断按压点所对应的按 键。
1、 多个按压点对应同一个按键。
此时, 所对应的该同一按键为该次按压操作对应的按键。
如图 11所示, 图中所示的按压点从左到右一次为按压点 1至 6, 对 于按压点 1至 6 (其中, 在按压点 6时用户停止按压 ), 由于按压点 1至 6对应的按键均按键 d, 因此将用户的行为判定为按下按键 d„
2、 多个按压点对应不同的按键。
此时判定准则为: 当最后一个按键对应的按压点数达到点数门限, 和 /或最后一个按键对应的持续时间达到时间门限,则确定该次按压操作 对应的按键为最后一个按键; 否则, 根据倒数第二个按键对应的按压点 数和按压点的持续时间进行判断; 具体为: 当倒数第二个按键对应的按 压点数为未达到点数门限且倒数第二个按键对应的持续时间未达到时 间门限, 则确定该次按压操作对应的按键为对应的最后一个按键, 否则 确定该次按压操作对应的按键为对应的倒数第二个按键。 以下以表 2所示的优选的判定准则为例进行判断。
表 2、 判定准则
Figure imgf000016_0001
由表 2可知:
( 1 )如果最后一个按键停留时间大于等于 20微秒(时间视具体平 台需要调整), 或者按压点数大于等于 3 个则判定终端被按下的是最后 一个按键。
( 2 )如杲最后一个按键停留时间小于 20微秒(时间视具体平台需 要调整), 并且坐标点小于 3个, 贝' J :
A、 如果前一个按键停留时间大于等于 20微秒(时间视具体平台需 要调整 ), 或者坐标点大于等于 3个则判定终端被按下的是前一个按键。
B、 如果前一个按键停留时间小于 20微秒(时间视具体平台需要调 整 ), 并且坐标点小于 3个则判定终端被按下的是最有一个按键。
例如: 如图 12所示, 用户在按压过程移动了按压点 , 按压点的轨迹 跨越了按键 s、 按键 d、 按键 f三个按键的显示区域。 此时, 如图 13所 示, 用户所按压的位置在按压点 1-6时, 系统提示按下按键为按键 s, 在按压点为 7-h时, 系统提示按下的按键为 d, 在按压点 i-k时, 系统提 示按下的按键为 f, 则当用户抬起按压点时只需要判断最后两个按键, 即按压点 7-h和 i-k的时间关系即可。
上述图 13中的按压点的信息列表如表 3所示。
表 3、 按压点的信息列表
Figure imgf000017_0001
根据表 3中的信息按照在不同按键中的持续时间以及按压点数情况 进行信息整合, 得到如表 4所示的整合后信息。
表 4、 按压点整合信息
Figure imgf000017_0002
s 6 38 坐标 7-坐标 1
忽略不参与 判断
d 11 94 坐标 i-坐标 7 f 3 10 坐标 k-坐标 i 根据上述的判决准则, 结合表 4可知, 判定结果为终端按下的按键 为 D。
需要说明的是, 判定准则根据不同机型, 不同系统, 均有差别, 具 体判定形式的改变不应视为对本发明保护范围的限制, 例如: 对于屏幕 较大的终端, 按压点数以 5为分界点进行判定。
步骤 207、 根据返回的信息执行相应操作。
具体地, 如果返回了有效的按键信息则执行按键相应的输入动作, 如果没有返回有效的按键信息则不执行相应的输入动作。
以图 3为例, 当确定该次按压操作对应的按键为字符或标点按键, 则输入对应字符或标点符号。 当确定为字符或标点以外的其它按键, 例 如, 当按键为 Space键时, 输入空格键; 当确定按键为 Backspace键时, 删除前一个字符; 当按键为 Enter键时, 执行换行操作。
需要说明的是, 上述本发明实施例是以扩展信息为 "按键的判定区 域" 和 "时间信息" 为例进行说明。 本发明实施例中的扩展信息还可以 为 "按键的判定区域" 或 "时间信息"。 其中, 若扩展信息为按键的判 定区域时, 上述步骤 205之后, 可直接判定根据最后一个按压点的位置 信息所确定的对应按键为该次按压操作对应的按键。 若扩展信息为按压 点的时间信息时, 上述按键的判定区域与按键的显示区域相同, 即直接 根据按压点的位置信息和时间信息判断所属的按键。 由于扩展信息为按 键的判定区域或按压点的时间信息时的具体判定步骤与本发明实施例 类似, 此处不再赘述。

否则, 根据倒数第二个按键对应的按压点数和按压点的持续时间进 行判断; 具体为: 当倒数第二个按键对应的按压点数为未达到点数门限 且倒数第二个按键对应的持续时间未达到时间门限, 则确定该次按压操 作对应的按键为对应的最后一个按键, 否则确定该次按压操作对应的按 键为对应的倒数第二个按键。
