这里将详细地对示例性实施例进行说明, 其示例表示在附图中。下面的描述涉及附图时, 除非另有表示, 不同附图中的相同数字表示相同或相似的要素。 以下示例性实施例中所描述 的实施方式并不代表与本发明相一致的所有实施方式。 相反, 它们仅是与如所附权利要求书 中所详述的、 本发明的一些方面相一致的装置和方法的例子。 图 1是根据一示例性实施例示出的一种输入方法的流程图, 如图 1所示, 该输入方法可 以用于包含触摸屏的电子设备中, 该输入方法包括如下步骤:
在步骤 101中, 接收作用于触摸屏上的点击信号;
在步骤 102中, 根据点击信号确定目标手指的落点位置;
在步骤 103中, 根据目标手指的初始位置与落点位置之间的位移、 位于初始位置上的目 标手指所对应的基本键的基本键位以及基本键位与目标手指所对应的其它键的其它键位在触 摸屏上的相对位置, 确定目标手指在落点位置时所对应的目标键位;
在步骤 104中, 输入与目标键位对应的目标字符。
综上所述, 本实施例提供的输入方法, 通过在接收到点击信号之后, 根据点击信号确定 目标手指的落点位置, 根据目标手指的初始位置和落点位置之间的位移、 位于初始位置上的 目标手指所对应的基本键的基本键位以及基本键与目标手指所对应的其它键的其它键位在触 摸屏上的相对位置, 确定目标手指在落点位置时对应的目标键位, 进而输入与目标键位对应 的目标字符; 解决了相关技术中输入准确率较低以及输入速度慢的问题; 达到了即使用户手 放置的位置与用户正常使用时的放置位置有所偏差, 但是由于目标键位是根据目标手指的初 始位置和落点位置之间的位移来确定, 所以电子设备仍然可以准确的输入用户需要的字符, 达到了提高输入准确率的效果; 同时, 由于目标键位是根据目标手指的初始位置和落点位置 之间的位移来确定, 所以用户可以根据自己在物理键盘中的盲打习惯在触摸屏上进行输入, 而不需要査看触摸屏上的虚拟键盘, 进而达到了提高输入速度的效果。 图 2A是根据另一示例性实施例示出的一种输入方法的流程图, 如图 2A所示, 该输入方 法可以用于包含触摸屏的电子设备中, 该输入方法包括如下步骤:
在步骤 201中, 获取用户手掌以自然舒适状态触摸触摸屏时手掌根部与不同手指之间的 相对位置关系;
当用户首次在电子设备上请求输入时, 为了后续步骤的执行, 电子设备可以请求获取用 户手掌以自然舒适状态触摸触摸屏时手掌根部与不同手指之间的相对位置关系。
在实际实现时, 当用户首次在电子设备上请求输入时, 电子设备可以显示一个用于提示 用户将手掌以自然舒适状态触摸触摸屏的显示界面, 用户在査看到电子设备显示的显示界面 之后, 将手掌以图 2B所示自然舒适状态触摸触摸屏, 此时电子设备可以相应的接收到用户手 掌以自然舒适状态触摸触摸屏时的触摸信号。 其中, 触摸信号包括用户手掌的手掌根部和手 掌中的 5根手指分别施加的信号。 在电子信号接收到触摸信号之后, 电子设备可以将触摸信 号中的各个信号的接收位置的相对位置关系确定为手掌的手掌根部和 5根手指的相对位置关 系, 详细请参考图 2C。
为了区分不同用户将手掌以自然舒适状态触摸触摸屏时手掌根部和不同手指之间的相对 位置关系, 电子设备可以获取手掌根部的掌纹和每根手指的指纹, 进而使用获取到的掌纹来 标识手掌根部, 使用获取到的指纹来标识不同手指。 在实际实现时, 当电子设备获取手掌根 部的掌纹时, 由于手掌皮肤的最外层也即掌纹的一层是不导电的, 而手掌里面的皮下层是导 电的, 所以当用户手掌落在电子设备的触摸屏上时, 电子设备可以通过给手掌皮肤带电, 检 测出掌纹的纹路, 进而通过测量掌纹引起的极小的电导率变化来获取手掌根部的掌纹, 本实 施例在此不再赘述。 类似的, 电子设备可以采用相同的获取方法来获取每根手指的指纹, 比 如, 电子设备可以获取图 2D所示的手指指纹。
在步骤 202中, 获取用户手掌以完全舒展状态触摸触摸屏时手掌根部与不同手指之间的 相对位置关系;
类似的, 当用户首次在电子设备上请求输入时, 为了后续步骤的执行, 电子设备还可以 获取用户手掌以完全舒展状态触摸触摸屏时手掌根部与不同手指之间的相对位置关系。
在实际实现时, 电子设备可以采用与步骤 201类似的获取方法来获取用户手掌以完全舒 展状态触摸触摸屏时手掌根部与不同手指之间的相对位置关系, 只是与步骤 201不同的是, 用户将把手掌以完全舒展的状态来触摸触摸屏, 详细示意图请参考图 2E。
需要说明的是, 本实施例只是以先执行步骤 201后执行步骤 202为例, 在实际实现时, 电子设备还可以同时执行步骤 201和步骤 202, 也可以先执行步骤 202后执行步骤 201, 本实 施例对其具体执行顺序并不做限定。
在步骤 203中, 接收作用于触摸屏上的触摸信号;
当用户需要在电子设备中请求输入时, 用户可以将手掌放置在电子设备的触摸屏上, 然 后通过手指在触摸屏上点击的方式来实现输入, 所以电子设备可以相应的接收到手掌作用于 触摸屏上的触摸信号。
在步骤 204中, 根据触摸信号确定目标手掌中的每根手指在触摸屏上的初始位置; 在电子设备接收到触摸信号之后, 电子设备可以根据触摸信号确定用户手掌中的每根手 指在触摸屏上的初始位置, 也即电子设备可以根据触摸信号确定目标手掌中的每根手指在触 摸屏上的初始位置。 其中, 目标手掌是点击触摸屏的目标手指所在的手掌, 比如, 当用户使 用左手中的手指点击触摸屏时, 目标手掌为左手掌; 当用户使用右手中的手指点击触摸屏时, 目标手掌为右手掌。
在实际实现时, 电子设备根据触摸信号确定目标手掌中的每根手指在触摸屏上的初始位 置的确定方式可以包括如下方式中的任一种:
第一种: 如果自然位置关系中使用掌纹标识手掌根部且使用指纹标识不同手指, 根据触 摸信号获取手掌根部的掌纹并确定掌纹在触摸屏上的起始位置; 获取与掌纹对应的自然位置 关系;根据掌纹在触摸屏上的起始位置和自然位置关系确定每根手指在触摸屏上的初始位置; 如果自然位置关系中使用掌纹标识手掌根部且使用指纹标识不同手指, 则电子设备在接 收到触摸信号之后, 电子设备可以获取手掌根部的掌纹, 并将接收到触摸信号时手掌根部的 落点位置作为手掌根部在触摸屏上所对应的起始位置。 由于用户手掌自然放置时, 同一用户 的用户手掌的手掌根部与每根手指之间的相对位置是基本不变的, 所以电子设备在获取到手 掌根部的掌纹以及手掌根部在触摸屏上所对应的起始位置之后, 电子设备可以获取与掌纹对 应的自然位置关系, 进而通过査询自然位置关系的方式来确定每根手指在触摸屏上的初始位 置。 其中, 自然位置关系是目标手掌以自然舒适状态触摸触摸屏时手掌根部与不同手指之间 的相对位置关系。
第二种: 如果自然位置关系和 /或极限位置关系中使用指纹标识不同手指, 在接收到触摸 信号之后, 根据触摸信号获取不同指纹; 根据不同指纹识别每根手指, 并根据触摸信号中每 个指纹的位置确定每根手指在触摸屏上的初始位置。
如果自然位置关系、 极限位置关系或者两者中都使用指纹来标识不同手指, 比如自然位 置关系中使用指纹来标识不同手指, 则在电子设备接收到触摸信号之后, 电子设备可以获取 施加触摸信号的不同手指的指纹以及每个指纹的位置, 通过获取到的指纹以及自然位置关系 中的指纹来识别不同手指, 进而将每个指纹的位置确定为每根手指在触摸屏上的位置。
在步骤 205中, 将每根手指在触摸屏上的初始位置构建为手指所对应的基本键的基本键 位; 在电子设备确定目标手掌中的每根手指的初始位置之后, 电子设备可以将每根手指的初 始位置构建为每根手指所对应的基本键的基本键位。 其中, 每根手指所对应的基本键是指用 户手掌以自然舒适状态触摸触摸屏时, 手掌中的每根手指所对应的默认字符的按键。
在实际实现时, 与用户在物理键盘中进行输入类似, 当用户手掌以自然舒适状态触摸触 摸屏时, 用户的左手从小指到拇指依次对应的基本键是 A'、 ' S 'Ό 和 '空格'; 右 手从小指到拇指依次对应的基本键是 :'、 Ί Κ'、 和 '空格', 所以在电子设备确定 每根手指的初始位置之后, 电子设备可以将每根手指的初始位置构建为每根手指所对应的基 本键的基本键位。 比如, 将左手小指在触摸屏上的初始位置构建为 'Α' 在触摸屏上的基本键 位, 将左手无名指在触摸屏上的初始位置构建为 在触摸屏上的基本键位; 具体请参考图 2F。
当然, 在实际实现时, 用户还可以通过设置项来为每根手指选择一个按键, 进而将手指 的初始位置构建为用户选择的按键在触摸屏上的键位位置, 本实施例对其具体构建方式并不 做限定。
在步骤 206中, 在接收到触摸信号之后, 获取手掌根部的掌纹;
在电子设备接收到触摸信号之后, 当自然位置关系和极限位置关系中使用掌纹标识手掌 根部时, 为了后续步骤的执行, 电子设备可以获取目标手掌的手掌根部的掌纹。
需要说明的是, 本实施例只是以步骤 206在步骤 204之后执行为例, 在实际实现时, 电 子设备可以同时执行步骤 206和步骤 204, 也可以先执行步骤 206再执行步骤 204, 本实施例 对其具体执行顺序并不做限定。
在步骤 207中, 根据所述手掌根部的掌纹检测是否已存储所述掌纹对应的自然位置关系 和所述极限位置关系, 若检测结果为未存储, 则执行步骤 208, 若检测结果为已存储, 则执 行步骤 209 ;
在电子设备获取到手掌根部的掌纹之后, 电子设备可以根据手掌根部的掌纹检测电子设 备中是否已存储自然位置关系和极限位置关系。 其中, 自然位置关系是目标手掌以自然舒适 状态触摸触摸屏时手掌根部与不同手指之间的相对位置关系; 极限位置关系是目标手掌以完 全舒展状态触摸触摸屏时手掌根部与不同手指之间的相对位置关系。
在实际实现时, 由于不同用户的手掌以自然舒适状态触摸触摸屏时手掌根部与不同手指 之间的相对位置关系以及手掌以完全舒展状态触摸触摸屏时手掌根部与不同手指之间的相对 位置关系都会有所不同, 并且区分不同用户的一种方法是通过用户掌纹来区分, 所以在电子 设备获取到手掌根部的掌纹之后, 电子设备可以检测是否已经存储有与获取到的手掌根部的 掌纹相匹配的用户手掌以自然舒适状态触摸触摸屏时手掌根部与不同手指之间的相对位置关 系以及手掌以完全舒展状态触摸触摸屏时手掌根部与不同手指之间的相对位置关系。
在步骤 208中, 获取所述自然位置关系和所述极限位置关系;
如果电子设备的检测结果为未存储自然位置关系和极限位置关系, 则说明该用户首次在 电子设备上进行输入, 所以此时电子设备可以获取自然位置关系和极限位置关系。 其中, 电 子设备获取自然位置关系的步骤可以包括:
第一, 接收作用于第一界面中的第一触摸信号, 第一界面用于提示用户将目标手掌以自 然舒适状态触摸触摸屏;
当电子设备检测到未存储自然位置关系和极限位置关系时,电子设备可以显示第一界面。 其中第一界面用于提示用于将目标手掌以自然舒适状态触摸触摸屏。
第二, 根据第一触摸信号确定目标手掌以自然舒适状态触摸触摸屏时手掌根部与不同手 指之间的相对位置关系, 将根据第一触摸信号确定的相对位置关系作为自然位置关系。
在电子设备接收到第一触摸信号之后, 电子设备根据第一触摸信号确定目标手掌以自然 舒适状态触摸触摸屏时手掌根部与不同手指之间的相对位置关系, 将根据第一触摸信号确定 的相对位置关系作为自然位置关系。
需要说明的是, 电子设备获取自然位置关系的获取方式与步骤 201中电子设备获取用户 手掌以自然舒适状态触摸触摸屏时手掌根部和不同手指之间的位置关系的获取方式类似, 详 细技术细节请参考步骤 201, 本步骤在此不再赘述。
电子设备获取极限位置关系的步骤可以包括:
第一, 接收作用于第二界面中的第二触摸信号, 第二界面用于提示用户将目标手掌以完 全舒展状态触摸触摸屏;
当电子设备检测到未存储自然位置关系和极限位置关系时,电子设备可以显示第二界面。 其中第二界面用于提示用于将目标手掌以完全舒展状态触摸触摸屏。
第二, 根据第二触摸信号确定目标手掌以完全舒展状态触摸触摸屏时手掌根部与不同手 指之间的相对位置关系, 将根据第二触摸信号确定的相对位置关系作为极限位置关系。
在电子设备接收到第二触摸信号之后, 电子设备根据第二触摸信号确定目标手掌以完全 舒展状态触摸触摸屏时手掌根部与不同手指之间的相对位置关系, 将根据第二触摸信号确定 的相对位置关系作为极限位置关系。
需要说明的一点是, 电子设备获取极限位置关系的获取方式与步骤 202中电子设备获取 用户手掌以完全舒展状态触摸触摸屏时手掌根部和不同手指之间的位置关系的获取方式类 似, 详细技术细节请参考步骤 202, 本步骤在此不再赘述。
需要说明的另一点是, 由于在电子设备获取自然位置关系和极限位置关系时, 用户手掌 会脱离触摸屏, 并且当用户再次用手掌触摸触摸屏进而请求输入时, 用户手掌中的各个手指 在触摸屏上的位置已经不再是步骤 204中获取到的初始位置, 所以, 电子设备在获取到自然 位置关系和极限位置关系后将再次执行步骤 204, 本实施例在此不再赘述。
在步骤 209中, 根据每根手指所对应的基本键的基本键位与每根手指所对应的其它键的 其它键位之间的预定排序方式、 目标手掌的手掌根部与不同手指之间的自然位置关系、 目标 手掌的手掌根部与不同手指之间的极限位置关系, 构建每根手指所对应的基本键位和其它键 位之间的相对位置;
与用户在物理键盘中输入类似是, 用户每根手指都会对应输入几个固定的字符, 比如左 手食指可以输入 '、 ' g V、 'h 'τ ' t '4' 和 5 ', 并且各个字符之间的排序方 式固定, 所以每根手指都对应几个按照预定排序方式排序的不同键位, 详细示意图请参考图 2G。 所以, 电子设备可以根据每根手指所对应的基本键的基本键位与每根手指所对应的其它 键的其它键位之间的预定排序方式、 目标手掌的手掌根部与不同手指之间的自然位置关系、 目标手掌的手掌根部与不同手指之间的极限位置关系, 构建每根手指所对应的基本键位和其 它键位之间的相对位置。
在实际实现时, 电子设备可以将极限位置关系中, 每根手指所能达到的最远位置构建为 该手指对应的各个键中距离基本键的基本键位最远的按键的键位位置。 比如, 根据图 2G可以 知道, 字符 ' 5 ' 对应的按键的位置与食指所对应的基本键 ' 在触摸屏上的基本键位的距 离最远, 所以电子设备可以将极限位置关系中食指所能达到的最远距离设置为字符 ' 5 ' 所对 应的键位, 并按照食指所对应的其它键位与 ' f ' 和 ' 5 ' 之间的预定排序方式继续构建, 进 而确定每根手指所对应的各个键位在触摸屏上的相对位置。
在步骤 210中, 接收作用于触摸屏上的点击信号;
当用户点击触摸屏上的某一区域时, 电子设备可以接收作用于触摸屏上的点击信号。 在步骤 211中, 根据点击信号确定目标手指的落点位置;
电子设备可以根据接收到的点击信号确定目标手指的落点位置。 在实际实现时, 电子设 备可以将接收点击信号的位置确定为目标手指的落点位置。 目标手指是指施加点击信号的手 指。
在步骤 212中, 根据目标手指的初始位置与落点位置之间的位移、 位于初始位置上的目 标手指所对应的基本键的基本键位以及基本键位与目标手指所对应的其它键的其它键位在触 摸屏上的相对位置, 确定目标手指在落点位置时所对应的目标键位;
电子设备确定目标键位的步骤可以包括:
第一, 在接收到点击信号后, 获取目标手指的指纹;
在电子设备接收到点击信号之后, 电子设备可以获取施加点击信号的目标手指的指纹。 其中, 电子设备获取目标手指的指纹的获取方式与步骤 201中电子设备获取手掌掌纹的获取 方式类似, 详细技术细节请参考步骤 201, 本步骤在此不再赘述。
第二, 根据目标手指的指纹査询目标手指的初始位置;
由于在步骤 204中, 电子设备已经确定目标手掌中的每根手指的初始位置, 所以在电子 设备确定目标手指的指纹之后,电子设备可以根据目标手指的指纹査询目标手指的初始位置。
在实际实现时, 电子设备根据目标手指的指纹査询目标手指的初始位置的査询方式可以 包括如下方式中的任一种:
第一种: 根据目标手指的指纹获取自然位置关系, 根据手掌根部的掌纹在触摸屏上的起 始位置和自然位置关系确定目标手指的指纹的初始位置。
由于自然位置关系中可以使用指纹来标识不同手指, 所以在电子设备获取到目标手指的 指纹之后电子设备可以获取自然位置关系, 并在査找到自然位置关系之后, 通过査询自然位 置关系的方式査询手掌根部在起始位置时目标手指在触摸屏上的初始位置。
第二种: 根据目标手指的指纹直接査询目标手指的初始位置。
与电子设备确定目标手掌中的每根手指的初始位置的第二种确定方式对应的是, 电子设 备在获取到目标手指的指纹之后, 电子设备可以直接査询与目标手指的指纹相对应的初始位 置。
第三, 计算目标手指的初始位置和落点位置之间的位移;
第四, 根据位移、 目标手指所对应的基本键的基本键位以及基本键位与目标手指所对应 的其它键的其它键位在触摸屏上的相对位置,确定目标手指在落点位置时所对应的目标键位。
由于目标手指在初始位置时所对应的基本键的基本键位已经确定, 且目标手指所对应的 基本键的基本键位与其它键的其它键位在触摸屏上的相对位置也已经确定, 所以在电子设备 获取到位移之后, 电子设备可以确定目标手指在落点位置时所对应的目标键位。
在步骤 213中, 输入与目标键位对应的目标字符。
在电子设备确定目标键位之后, 电子设备即可输入与目标键位对应的目标字符。 比如, 电子设备确定的目标键位为 所在的键位, 则电子设备可以输入目标字符 '。
综上所述, 本实施例提供的输入方法, 通过在接收到点击信号之后, 根据点击信号确定 目标手指的落点位置, 根据目标手指的初始位置和落点位置之间的位移、 位于初始位置上的 目标手指所对应的基本键的基本键位以及基本键与目标手指所对应的其它键的其它键位在触 摸屏上的相对位置, 确定目标手指在落点位置时对应的目标键位, 进而输入与目标键位对应 的目标字符; 解决了相关技术中输入准确率较低以及输入速度慢的问题; 达到了即使用户手 放置的位置与用户正常使用时的放置位置有所偏差, 但是由于目标键位是根据目标手指的初 始位置和落点位置之间的位移来确定, 所以电子设备仍然可以准确的输入用户需要的字符, 达到了提高输入准确率的效果; 同时, 由于目标键位是根据目标手指的初始位置和落点位置 之间的位移来确定, 所以用户可以根据自己在物理键盘中的盲打习惯在触摸屏上进行输入, 而不需要査看触摸屏上的虚拟键盘, 进而达到了提高输入速度的效果。
同时, 本实施例在构建每根手指所对应的各个键的键位在触摸屏上的相对位置之前, 先 检测电子设备中是否已经存储有自然位置关系和极限位置关系, 从而在检测结果为未存储自 然位置关系和极限位置关系时, 先获取自然位置关系和极限位置关系, 然后在用户再次请求 输入时再进行构建, 避免了当请求输入的用户发生变化时, 电子设备无法构建每根手指所对 应的各个键的键位在触摸屏上的相对位置, 电子设备无法确定目标手指的落点位置所对应的 目标键位也即无法输入目标字符的问题。 需要说明的是, 请参考图 2H, 为了避免用户在施加触摸信号之后施加点击信号之前, 用 户手掌在触摸屏上的位置发生偏移, 从而导致用户施加点击信号时目标手指的初始位置已经 不再是用户施加触摸信号时目标手指的位置, 电子设备根据目标手指的初始位置确定的目标 键位已经不再是用户实际请求点击的目标键位, 也即电子设备最终输入的目标字符不是用户 实际请求输入的字符的问题, 在电子设备执行步骤 212之前, 电子设备可以执行如下步骤: 在步骤 214中, 获取目标手掌的手掌根部在触摸屏上的当前位置;
为了后续步骤的执行, 电子设备可以获取目标手掌的手掌根部在触摸屏上的当前位置。 在实际实现时, 电子设备可以检测目标手掌的掌纹在触摸屏上的落点位置, 并将检测得到的 落点位置作为目标手掌的手掌根部在触摸屏上的当前位置。
在步骤 215中, 检测手掌根部的当前位置是否与电子设备接收到触摸信号时目标手掌的 手掌根部的起始位置匹配;
为了判断手掌根部的位置是否发生变化, 电子设备可以检测手掌根部的当前位置是否与 电子设备接收到触摸信号时目标手掌的手掌根部的起始位置匹配。
相应的, 在步骤 212中, 电子设备用于在检测结果为匹配时, 执行根据目标手指的初始 位置与落点位置之间的位移、 位于初始位置上的目标手指所对应的基本键的基本键位以及基 本键位与目标手指所对应的其它键的其它键位在触摸屏上的相对位置, 确定目标手指在落点 位置时所对应的目标键位的步骤。
如果电子设备的检测结果为匹配, 则说明手掌根部的位置未发生变化, 也即目标手指的 初始位置未发生变化, 此时, 电子设备可以直接执行步骤 212;
而如果电子设备的检测结果为不匹配, 则说明手掌根部的位置已经发生变化, 此时为了 避免电子设备确定的目标键位不是用户实际需要点击的键位, 也即电子设备实际输入的目标 字符不是用户实际想要输入的字符的问题, 电子设备将重新进入步骤 204, 重新确定目标手 指的初始位置, 本实施例在此不再赘述。 下述为本公开装置实施例, 可以用于执行本公开方法实施例。 对于本公开装置实施例中 未披露的细节, 请参照本公开方法实施例。
